  • Fix rake routes not showing the right format when nesting multiple routes.

    See #18373.

    Ravil Bayramgalin

  • Add ability to override default form builder for a controller.

    class AdminController < ApplicationController
  default_form_builder AdminFormBuilder
end

    Kevin McPhillips

  • For actions with no corresponding templates, render head :no_content instead of raising an error. This allows for slimmer API controller methods that simply work, without needing further instructions.

    See #19036.

    Stephen Bussey

  • Provide friendlier access to request variants.

    request.variant = :phone
request.variant.phone?  # true
request.variant.tablet? # false

request.variant = [:phone, :tablet]
request.variant.phone?                  # true
request.variant.desktop?                # false
request.variant.any?(:phone, :desktop)  # true
request.variant.any?(:desktop, :watch)  # false

    George Claghorn

  • Fix regression where a gzip file response would have a Content-type, even when it was a 304 status code.

    See #19271.

    Kohei Suzuki

  • Fix handling of empty X_FORWARDED_HOST header in raw_host_with_port.

    Previously, an empty X_FORWARDED_HOST header would cause Actiondispatch::Http:URL.raw_host_with_port to return nil, causing Actiondispatch::Http:URL.host to raise a NoMethodError.

    Adam Forsyth

  • Drop request class from RouteSet constructor.

    If you would like to use a custom request class, please subclass and implement the request_class method.

    tenderlove@ruby-lang.org

  • Fallback to ENV['RAILS_RELATIVE_URL_ROOT'] in url_for.

    Fixed an issue where the RAILS_RELATIVE_URL_ROOT environment variable is not prepended to the path when url_for is called. If SCRIPT_NAME (used by Rack) is set, it takes precedence.

    Fixes #5122.

    Yasyf Mohamedali

  • Partitioning of routes is now done when the routes are being drawn. This helps to decrease the time spent filtering the routes during the first request.

    Guo Xiang Tan

  • Fix regression in functional tests. Responses should have default headers assigned.

    See #18423.

    Jeremy Kemper, Yves Senn

  • Deprecate AbstractController#skip_action_callback in favor of individual skip_callback methods (which can be made to raise an error if no callback was removed).

    Iain Beeston

  • Alias the ActionDispatch::Request#uuid method to ActionDispatch::Request#request_id. Due to implementation, config.log_tags = [:request_id] also works in substitute for config.log_tags = [:uuid].

    David Ilizarov

  • Change filter on /rails/info/routes to use an actual path regexp from rails and not approximate javascript version. Oniguruma supports much more extensive list of features than javascript regexp engine.

    Fixes #18402.

    Ravil Bayramgalin

  • Non-string authenticity tokens do not raise NoMethodError when decoding the masked token.

    Ville Lautanala

  • Add http_cache_forever to Action Controller, so we can cache a response that never gets expired.

    arthurnn

  • ActionController#translate supports symbols as shortcuts. When shortcut is given it also lookups without action name.

    Max Melentiev

  • Expand ActionController::ConditionalGet#fresh_when and stale? to also accept a collection of records as the first argument, so that the following code can be written in a shorter form.

    # Before
def index
  @articles = Article.all
  fresh_when(etag: @articles, last_modified: @articles.maximum(:updated_at))
end

# After
def index
  @articles = Article.all
  fresh_when(@articles)
end

    claudiob

  • Explicitly ignored wildcard verbs when searching for HEAD routes before fallback

    Fixes an issue where a mounted rack app at root would intercept the HEAD request causing an incorrect behavior during the fall back to GET requests.

    Example:

    draw do
    get '/home' => 'test#index'
    mount rack_app, at: '/'
end
head '/home'
assert_response :success

    In this case, a HEAD request runs through the routes the first time and fails to match anything. Then, it runs through the list with the fallback and matches get '/home'. The original behavior would match the rack app in the first pass.

    Terence Sun

  • Migrating xhr methods to keyword arguments syntax in ActionController::TestCase and ActionDispatch::Integration

    Old syntax:

    xhr :get, :create, params: { id: 1 }

    New syntax example:

    get :create, params: { id: 1 }, xhr: true

    Kir Shatrov

  • Migrating to keyword arguments syntax in ActionController::TestCase and ActionDispatch::Integration HTTP request methods.

    Example:

    post :create, params: { y: x }, session: { a: 'b' }
get :view, params: { id: 1 }
get :view, params: { id: 1 }, format: :json

    Kir Shatrov

  • Preserve default url options when generating URLs.

    Fixes an issue that would cause default_url_options to be lost when generating URLs with fewer positional arguments than parameters in the route definition.

    Tekin Suleyman

  • Deprecate *_via_redirect integration test methods.

    Use follow_redirect! manually after the request call for the same behavior.

    Aditya Kapoor

  • Add ActionController::Renderer to render arbitrary templates outside controller actions.

    Its functionality is accessible through class methods render and renderer of ActionController::Base.

    Ravil Bayramgalin

  • Support :assigns option when rendering with controllers/mailers.

    Ravil Bayramgalin

  • Default headers, removed in controller actions, are no longer reapplied on the test response.

    Jonas Baumann

  • Deprecate all *_filter callbacks in favor of *_action callbacks.

    Rafael Mendonça França

  • Allow you to pass prepend: false to protect_from_forgery to have the verification callback appended instead of prepended to the chain. This allows you to let the verification step depend on prior callbacks.

    Example:

    class ApplicationController < ActionController::Base
  before_action :authenticate
  protect_from_forgery prepend: false, unless: -> { @authenticated_by.oauth? }

  private
    def authenticate
      if oauth_request?
        # authenticate with oauth
        @authenticated_by = 'oauth'.inquiry
      else
        # authenticate with cookies
        @authenticated_by = 'cookie'.inquiry
      end
    end
end

    Josef Šimánek

  • Remove ActionController::HideActions.

    Ravil Bayramgalin

  • Remove respond_to/respond_with placeholder methods, this functionality has been extracted to the responders gem.

    Carlos Antonio da Silva

  • Remove deprecated assertion files.

    Rafael Mendonça França

  • Remove deprecated usage of string keys in URL helpers.

    Rafael Mendonça França

  • Remove deprecated only_path option on *_path helpers.

    Rafael Mendonça França

  • Remove deprecated NamedRouteCollection#helpers.

    Rafael Mendonça França

  • Remove deprecated support to define routes with :to option that doesn't contain #.

    Rafael Mendonça França

  • Remove deprecated ActionDispatch::Response#to_ary.

    Rafael Mendonça França

  • Remove deprecated ActionDispatch::Request#deep_munge.

    Rafael Mendonça França

  • Remove deprecated ActionDispatch::Http::Parameters#symbolized_path_parameters.

    Rafael Mendonça França

  • Remove deprecated option use_route in controller tests.

    Rafael Mendonça França

  • Ensure append_info_to_payload is called even if an exception is raised.

    Fixes an issue where when an exception is raised in the request the additional payload data is not available.

    See:

    Dieter Komendera, Margus Pärt

  • Correctly rely on the response's status code to handle calls to head.

    Robin Dupret

  • Using head method returns empty response_body instead of returning a single space " ".

    The old behavior was added as a workaround for a bug in an early version of Safari, where the HTTP headers are not returned correctly if the response body has a 0-length. This is been fixed since and the workaround is no longer necessary.

    Fixes #18253.

    Prathamesh Sonpatki

  • Fix how polymorphic routes works with objects that implement to_model.

    Travis Grathwell

  • Stop converting empty arrays in params to nil.

    This behaviour was introduced in response to CVE-2012-2660, CVE-2012-2694 and CVE-2013-0155

    ActiveRecord now issues a safe query when passing an empty array into a where clause, so there is no longer a need to defend against this type of input (any nils are still stripped from the array).

    Chris Sinjakli

  • Fixed usage of optional scopes in url helpers.

    Alex Robbin

  • Fixed handling of positional url helper arguments when format: false.

    Fixes #17819.
