• Introducing Variants

  We often want to render different html/json/xml templates for phones, tablets, and desktop browsers. Variants make it easy.

  The request variant is a specialization of the request format, like :tablet, :phone, or :desktop.

  You can set the variant in a before_action:

  request.variant = :tablet if request.user_agent =~ /iPad/
  

  Respond to variants in the action just like you respond to formats:

  respond_to do |format|
    format.html do |html|
      html.tablet # renders app/views/projects/show.html+tablet.erb
      html.phone { extra_setup; render ... }
    end
  end
  

  Provide separate templates for each format and variant:

  app/views/projects/show.html.erb
  app/views/projects/show.html+tablet.erb
  app/views/projects/show.html+phone.erb
  

  Łukasz Strzałkowski

• Fix header Content-Type: #<Mime::NullType:...> in localized template.

  When localized template has no format in the template name, the response now has the default and correct content-type.

  Fixes #13064.

  Angelo Capilleri

• Try to escape each part of a url correctly when using a redirect route.

  Fixes #13110.

  Andrew White

• Better error message for typos in assert_response argument.

  When the response type argument to assert_response is not a known response type, assert_response now throws an ArgumentError with a clear message. This is intended to help debug typos in the response type.

  Victor Costan

• Fix formatting for rake routes when a section is shorter than a header.

  Sıtkı Bağdat

• Take a hash with options inside array in #url_for.

  Example:

  url_for [:new, :admin, :post, { param: 'value' }]
  # => http://example.com/admin/posts/new?param=value
  

  Andrey Ognevsky

• Add session#fetch method

  fetch behaves similarly to Hash#fetch, with the exception that the returned value is always saved into the session.

  It returns a value from the hash for the given key. If the key can’t be found, there are several options:

  • With no other arguments, it will raise an KeyError exception.
  • If a default value is given, then that will be returned.
  • If the optional code block is specified, then that will be run and its result returned.

  Damien Mathieu

• Don't let strong parameters mutate the given hash via fetch

  Create a new instance if the given parameter is a Hash instead of passing it to the convert_hashes_to_parameters method since it is overriding its default value.

  Brendon Murphy, Doug Cole

• Add params option to button_to form helper, which renders the given hash as hidden form fields.

  Andy Waite

• Make assets helpers work in the controllers like it works in the views.

  Example:

  # config/application.rb
  config.asset_host = 'http://mycdn.com'
  
  ActionController::Base.helpers.asset_path('fallback.png')
  # => http://mycdn.com/assets/fallback.png
  

  Fixes #10051.

  Tima Maslyuchenko

• Respect SCRIPT_NAME when using redirect with a relative path

  Example:

  # application routes.rb
  mount BlogEngine => '/blog'
  
  # engine routes.rb
  get '/admin' => redirect('admin/dashboard')
  

  This now redirects to the path /blog/admin/dashboard, whereas before it would've generated an invalid url because there would be no slash between the host name and the path. It also allows redirects to work where the application is deployed to a subdirectory of a website.

  Fixes #7977.

  Andrew White

• Fixing repond_with working directly on the options hash This fixes an issue where the respond_with worked directly with the given options hash, so that if a user relied on it after calling respond_with, the hash wouldn't be the same.

  Fixes #12029.

  bluehotdog

• Fix ActionDispatch::RemoteIp::GetIp#calculate_ip to only check for spoofing attacks if both HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR are set.

  Fixes #10844.

  Tamir Duberstein

• Strong parameters should permit nested number as key.

  Fixes #12293.

  kennyj

• Fix regex used to detect URI schemes in redirect_to to be consistent with RFC 3986.

  Derek Prior

• Fix incorrect assert_redirected_to failure message for protocol-relative URLs.

  Derek Prior

• Fix an issue where router can't recognize downcased url encoding path.

  Fixes #12269.

  kennyj

• Fix custom flash type definition. Misusage of the _flash_types class variable caused an error when reloading controllers with custom flash types.

  Fixes #12057.

  Ricardo de Cillo

• Do not break params filtering on nil values.

  Fixes #12149.

  Vasiliy Ermolovich

• Development mode exceptions are rendered in text format in case of XHR request.

  Kir Shatrov

• Fix an issue where :if and :unless controller action procs were being run before checking for the correct action in the :only and :unless options.

  Fixes #11799.

  Nicholas Jakobsen

• Fix an issue where assert_dom_equal and assert_dom_not_equal were ignoring the passed failure message argument.

  Fixes #11751.

  Ryan McGeary

• Allow REMOTE_ADDR, HTTP_HOST and HTTP_USER_AGENT to be overridden from the environment passed into ActionDispatch::TestRequest.new.

  Fixes #11590.

  Andrew White

• Fix an issue where Journey was failing to clear the named routes hash when the routes were reloaded and since it doesn't overwrite existing routes then if a route changed but wasn't renamed it kept the old definition. This was being masked by the optimised url helpers so it only became apparent when passing an options hash to the url helper.

  Andrew White

• Skip routes pointing to a redirect or mounted application when generating urls using an options hash as they aren't relevant and generate incorrect urls.

  Fixes #8018.

  Andrew White

• Move MissingHelperError out of the ClassMethods module.

  Yves Senn

• Fix an issue where rails raise exception about missing helper where it should throw LoadError. When helper file exists and only loaded file from this helper does not exist rails should throw LoadError instead of MissingHelperError.

  Piotr Niełacny

• Fix ActionDispatch::ParamsParser#parse_formatted_parameters to rewind body input stream on parsing json params.

  Fixes #11345.

  Yuri Bol, Paul Nikitochkin

• Ignore spaces around delimiter in Set-Cookie header.

  Yamagishi Kazutoshi

• Remove deprecated Rails application fallback for integration testing, set ActionDispatch.test_app instead.

  Carlos Antonio da Silva

• Remove deprecated page_cache_extension config.

  Francesco Rodriguez

• Remove deprecated constants from Action Controller:

  ActionController::AbstractRequest  => ActionDispatch::Request
  ActionController::Request          => ActionDispatch::Request
  ActionController::AbstractResponse => ActionDispatch::Response
  ActionController::Response         => ActionDispatch::Response
  ActionController::Routing          => ActionDispatch::Routing
  ActionController::Integration      => ActionDispatch::Integration
  ActionController::IntegrationTest  => ActionDispatch::IntegrationTest
  

  Carlos Antonio da Silva

• Fix Mime::Type.parse when bad accepts header is looked up. Previously it was setting request.formats with an array containing a nil value, which raised an error when setting the controller formats.

  Fixes #10965.

  Becker

• Merge :action from routing scope and assign endpoint if both :controller and :action are present. The endpoint assignment only occurs if there is no :to present in the options hash so should only affect routes using the shorthand syntax (i.e. endpoint is inferred from the path).

  Fixes #9856.

  Yves Senn, Andrew White

• Action View extracted from Action Pack.

  Piotr Sarnacki, Łukasz Strzałkowski

• Fix removing trailing slash for mounted apps.

  Fixes #3215.
