• Escape format, negative_format and units options of number helpers

    Fixes: CVE-2014-0081

Rails 4.0.2 (December 02, 2013)

  • Ensure simple_format escapes its html attributes. This fixes CVE-2013-6416

  • Deep Munge the parameters for GET and POST Fixes CVE-2013-6417

  • Stop using i18n's built in HTML error handling. Fixes: CVE-2013-4491

  • Escape the unit value provided to number_to_currency Fixes CVE-2013-6415

  • Only use valid mime type symbols as cache keys CVE-2013-6414

Rails 4.0.1 (November 01, 2013)

  • Respect SCRIPT_NAMEwhen using redirectwith 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.

    Joel Cogen

  • 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.

Rails 4.0.0 (June 25, 2013)

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

    Fixes #9856

    Yves Senn, Andrew White

  • Use a case insensitive URI Regexp for asset_path.

    This fix a problem where the same asset path using different case are generating different URIs.

    Before:

    image_tag("HTTP://google.com")
    # => "<img alt=\"Google\" src=\"/assets/HTTP://google.com\" />"
    image_tag("http://google.com")
    # => "<img alt=\"Google\" src=\"http://google.com\" />"
    

    After:

    Bryan Ricker

  • Add support for passing custom url options other than :host and custom status and flash options to force_ssl.

    Andrew White

  • The force_sslcommand 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

  • Element of the collection for options_from_collection_for_selecthelper can optionally contain html attributes as the last element of the array as options_for_selecthelper.

    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_fieldthe []is not appended. Fixes #9830.

    Ryan McGeary

  • Add block support for the mail_tohelper, similar to the link_tohelper.

    Sam Pohlenz

  • Automatically configure cookie-based sessions to be encrypted if secret_key_baseis set, falling back to signed if only secret_tokenis set. Automatically upgrade existing signed cookie-based sessions from Rails 3.x to be encrypted if both secret_key_baseand secret_tokenare set, or signed with the new key generator if only secret_tokenis set. This leaves only the config.session_store :cookie_storeoption and removes the two new options introduced in 4.0.0.beta1: encrypted_cookie_storeand 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 nilresulted in no layout which differed from the layout nilbehavior. To get the "no layout" behavior just return falseinstead of nilfor layout.

    Chris Nicola

  • Create UpgradeLegacySignedCookieJarto transparently upgrade existing signed cookies generated by Rails 3.x to avoid invalidating them when upgrading to Rails 4.x.

    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_

  • 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][]" ...>

    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#newraise more meaningful exception message.

    Thierry Zires

  • Fix respond_tonot 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_altmethod 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_namethus 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_templatecan 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_forwith array HTML option. It would embed array as string instead of joining it like content_tagdoes:

    content_tag(:td, class: ["foo", "bar"]){}
    # => <td class="foo bar"></td>
    

    Before:

    content_tag_for(:td, item, class: ["foo", "bar"])
    # => <td class="item [&quot;foo&quot;, &quot;bar&quot;]" id="item_1"></td>
    

    After:

    content_tag_for(:td, item, class: ["foo", "bar"])
    # => <td class="item foo bar" id="item_1"></td>

  • Fix CSRF protection and current_url?helper to work with HEAD requests now that ActionDispatch::Headhas been removed in favor of Rack::Head.

    Michiel Sikkes

  • Change asset_pathto not include SCRIPT_NAMEwhen 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_fordirectly. 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 :selectedto be set on date_selecttag helper.

    Jamis Buck

  • image_submit_tagwill set altattribute 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 :objector :collectionwould 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_urlwhen using trailing_slash: trueFixes #8700.

    Before:

    Matt Venables

  • Prevent raising EOFErroron 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_ifand cache_unlessfor conditional fragment caching:

    <% end %>
    
    # and
    
    <%= cache_unless condition, project do %>
      <b>All the topics on this project</b>
      <%= render project.topics %>
    <% end %>

  • 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

  • assert_templateis no more passing with what ever string that matches with the template name.

    Before when we have a template /layout/hello.html.erb, assert_templatewas 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.

    Arun Agrawal + Guillermo Iguaran

  • Support multiple etags in If-None-Match header. Travis Warlick

  • Allow to configure how unverified request will be handled using :withoption in protect_from_forgerymethod.

    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

    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#cachecalls (originally spiked in the cache_digestsplugin) 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::RecordIdentifierin 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_idand dom_classdirectly, in favor of ActionView::RecordIdentifier.dom_idand dom_class. RecordIdentifierwill be removed from ActionController::Basein Rails 4.1.

    Piotr Sarnacki

  • Fix ActionView::RecordIdentifierto work as a singleton. Piotr Sarnacki

  • Deprecate Template#mime_type, it will be removed in Rails 4.1 in favor of #type. Piotr Sarnacki

  • Fix select_tagwhen option_tagsis 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]

    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_functionand 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.

    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

    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'

  • Make possible to use a block in button_toif 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.

  • Removed old text helper apis from highlight, excerptand 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_within favor of data: { disable_with: "Text" }option from submit_tag, button_tagand button_to helpers.

    Carlos Galdino + Rafael Mendonça França

  • Remove :mouseoveroption from image_taghelper. Rafael Mendonça França

  • The selectmethod (select tag) forces :include_blankif requiredis true and display sizeis one and multipleis not true. Angelo Capilleri

  • Copy literal route constraints to defaults so that url generation know about them. The copied constraints are :protocol, :subdomain, :domain, :hostand :port.

    Andrew White

  • respond_toand respond_withnow raise ActionController::UnknownFormatinstead of directly returning head 406. The exception is rescued and converted to 406 in the exception handling middleware. Steven Soroka

  • Allows assert_redirected_toto match against a regular expression. Andy Lindeman

  • Add backtrace to development routing error page. Richard Schneeman

  • Replace include_secondsboolean argument with include_seconds: trueoption in distance_of_time_in_wordsand 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/javascriptinstead of application/json. omjokine

  • Allow to lazy load default_form_builderby passing a Stringinstead of a constant. Piotr Sarnacki

  • Session arguments passed to processcalls 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

  • In the routes DSL the :viaoption of matchis now mandatory.

    For routes that respond to one single verb it is recommended to use the more specific macros get, post, etc. instead. You can still map all HTTP verbs to one action with match, but it has to be explictly configured using :via => :all.

    José Valim and Yehuda Katz

  • Add indexmethod 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_formsto 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 trueor explicitly pass authenticity_token: true in form options.

  • Added ActionDispatch::SSLmiddleware that when included force all the requests to be under HTTPS protocol. Rafael Mendonça França

  • Add include_hiddenoption to select tag. With include_hidden: falseselect with multiple attribute doesn't generate hidden input with blank value. Vasiliy Ermolovich

  • Removed default sizeoption from the text_field, search_field, telephone_field, url_field, email_fieldhelpers. Philip Arndt

  • Removed default colsand rowsoptions from the text_areahelper. Philip Arndt

  • Adds support for layouts when rendering a partial with a given collection. serabe

  • Allows the route helper rootto 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_sslin development. This is a change of behavior - use a :ifcondition 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 patchmethod, and understand :patchin the existing places where a verb is configured, like :via.

    • New method patchavailable in functional tests.

    • If :patchis the default verb for updates, edits are tunneled as PATCH rather than as PUT, and routing acts accordingly.

    • New method patch_via_redirectavailable in integration tests.

    dlee

  • expires_inaccepts a must_revalidateflag. If true, “must-revalidate” is added to the Cache-Control header. fxn

  • Add date_fieldand date_field_taghelpers which render an input[type="date"]tag Olek Janiszewski

  • Adds image_url, javascript_url, stylesheet_url, audio_url, video_url, and font_urlto assets tag helper. These URL helpers will return the full path to your assets. This is useful when you are going to reference this asset from external host. Prem Sichanugrist

  • Default responder will now always use your overridden block in respond_withto render your response. Prem Sichanugrist

  • Allow value_methodand text_methodarguments from collection_selectand options_from_collection_for_selectto receive an object that responds to :call, such as a proc, to evaluate the option in the current element context. This works the same way with collection_radio_buttonsand collection_check_boxes.

    Carlos Antonio da Silva + Rafael Mendonça França

  • Add collection_check_boxesform 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_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 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

  • Add collection_radio_buttonsform helper, similar to collection_select: Example:

    collection_radio_buttons :post, :author_id, Author.all, :id, :name
    # Outputs something like:
    <input id="post_author_id_1" name="post[author_id]" type="radio" value="1" />
    <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>

    The label/radio_button pairs can be customized with a block.
