  • Fix ActionDispatch::Assertions::ResponseAssertions#assert_redirected_to does not show user-supplied message.

    Issue: when assert_redirected_tofails due to the response redirect not matching the expected redirect the user-supplied message (second parameter) is not shown. This message is only shown if the response is not a redirect.

    Alexey Chernenkov

Rails 3.2.14 (Jul 22, 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

  • Always escape the result of link_to_unlessmethod.


    link_to_unless(true, '<b>Showing</b>', 'github.com')
    # => "<b>Showing</b>"


    link_to_unless(true, '<b>Showing</b>', 'github.com')
    # => "&lt;b&gt;Showing&lt;/b&gt;"


  • 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.


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


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

    David Celis + Rafael Mendonça França

  • 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

  • Fix assets loading performance in 3.2.13.

    Issue #8756 uses Sprockets for resolving files that already exist on disk, for those files their extensions don't need to be rewritten.

    Fixes #9803.

    Fred Wu

  • Fix ActionController#action_missingnot being called. Fixes #9799.

    Janko Luin

  • ActionView::Helpers::NumberHelper#number_to_humanreturns the number unaltered when the units hash does not contain the needed key, e.g. when the number provided is less than the largest key provided.

Rails 3.2.13 (Mar 18, 2013)

  • Fix incorrectly appended square brackets to a multiple select box if an explicit name has been given and it already ends with "[]".


    select(:category, [], {}, multiple: true, name: "post[category][]")
    # => <select name="post[category][][]" ...>

    Backport #9616.

    Olek Janiszewski

  • 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. Backport #9361.

    Yves Senn

  • Fix a bug in content_tag_forthat prevents it for work without a block.


  • Clear url helper methods when routes are reloaded by removing the methods explicitly rather than just clearing the module because it didn't work properly and could be the source of a memory leak.

    Andrew White

  • Fix a bug in ActionDispatch::Request#raw_postthat caused env['rack.input']to be read but not rewound.

    Matt Venables

  • More descriptive error messages when calling render :partial with an invalid :layoutargument.

Rails 3.2.10 (Jan 2, 2013)

  • No changes.

Rails 3.2.9 (Nov 12, 2012)

  • Clear url helpers when reloading routes.

    Santiago Pastorino

  • Revert the shorthand routes scoped with :moduleoption fix This added a regression since it is changing the URL mapping. This makes the stable release backward compatible.

    Rafael Mendonça França

  • Revert the assert_templatefix to not pass with ever string that matches the template name. This added a regression since people were relying on this buggy behavior. This will introduce back #3849 but this stable release will be backward compatible. Fixes #8068.

    Rafael Mendonça França

  • Revert the rename of internal variable on ActionController::TemplateAssertions to prevent naming collisions. This added a regression related with shoulda-matchers, since it is expecting the instance variable @layouts. This will introduce back #7459 but this stable release will be backward compatible. Fixes #8068.

    Rafael Mendonça França

  • Accept :remote as symbolic option for link_tohelper. Riley Lynch

  • Warn when the :localsoption is passed to assert_templateoutside of a view test case Fix #3415

    Yves Senn

  • Rename internal variables on ActionController::TemplateAssertions to prevent naming collisions. @partials, @templates and @layouts are now prefixed with an underscore. Fix #7459

    Yves Senn

  • resourceand resourcesdon't modify the passed options hash Fix #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_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.


  • Handle ActionDispatch::Http::UploadedFilelike Rack::Test::UploadedFile, don't call to_param on it. Since Rack::Test::UploadedFileisn't API compatible this is needed to test file uploads that rely on tempfilebeing available.

    Tim Vandecasteele

  • Respect config.digest = falsefor asset_path

    Previously, the asset_pathinternals only respected the :digestoption, but ignored the global config setting. This meant that config.digest = falsecould not be used in conjunction with config.compile = falsethis corrects the behavior.

    Peter Wagenet

  • Fix #7646, the log now displays the correct status code when an exception is raised.

    Yves Senn

  • Fix handling of date selects when using both disabled and discard options. Fixes #7431.

    Vasiliy Ermolovich

  • Fix select_tag when option_tags is nil. Fixes #7404.

    Sandeep Ravichandran

  • javascript_include_tag :allwill now not include application.jsif the file does not exists. Prem Sichanugrist

  • Support cookie jar options (e.g., domain :all) for all session stores. Fixes GH#3047, GH#2483.

    Ravil Bayramgalin

  • Performance Improvement to send_file: Avoid having to pass an open file handle as the response body. Rack::Sendfile will usually intercept the response and just uses the path directly, so no reason to open the file. This performance improvement also resolves an issue with jRuby encodings, and is the reason for the backport, see issue #6844.

    Jeremy Kemper & Erich Menge

Rails 3.2.8 (Aug 9, 2012)

  • There is an XSS vulnerability in the strip_tags helper in Ruby on Rails, the helper doesn't correctly handle malformed html. As a result an attacker can execute arbitrary javascript through the use of specially crafted malformed html.

    Marek from Nethemba (www.nethemba.com) & Santiago Pastorino

  • When a "prompt" value is supplied to the select_taghelper, the "prompt" value is not escaped. If untrusted data is not escaped, and is supplied as the prompt value, there is a potential for XSS attacks. Vulnerable code will look something like this: select_tag("name", options, :prompt => UNTRUSTED_INPUT)

    Santiago Pastorino

  • Reverted the deprecation of :confirm. Rafael Mendonça França

  • Reverted the deprecation of :disable_with. Rafael Mendonça França

Rails 3.2.6 (Jun 12, 2012)

  • nil is removed from array parameter values


  • Deprecate :confirmin favor of ':data => { :confirm => "Text" }'option for button_to, button_tag, image_submit_tag, link_toand submit_taghelpers.

    Carlos Galdino

    Carlos Galdino + Rafael Mendonça França

  • Deprecate :mouseoveroption for image_taghelper. Rafael Mendonça França

  • Deprecate button_to_functionand link_to_function helpers. Rafael Mendonça França

  • Don't break Haml with textarea newline fix. GH #393, #4000, #5190, #5191

  • Fix the redirect when it receive blocks with arity of 1. Closes #5677

  • Strip [nil] from parameters hash. Thanks to Ben Murphy for reporting this! CVE-2012-2660

Rails 3.2.3 (March 30, 2012)

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

  • Fix #5632, render :inline set the proper rendered format. Santiago Pastorino

  • Fix textarea rendering when using plugins like HAML. Such plugins encode the first newline character in the content. This issue was introduced in github.com/rails/rails/pull/5191 James Coleman

  • Remove the leading n added by textarea on assert_select. Santiago Pastorino

  • Add config.action_view.embed_authenticity_token_in_remote_forms (defaults to true) which allows to set if authenticity token will be included by default in remote forms. If you change it to false, you can still force authenticity token by passing :authenticity_token => true in form options Piotr Sarnacki

  • Do not include the authenticity token in forms where remote: true as ajax forms use the meta-tag value DHH

  • Turn off verbose mode of rack-cache, we still have X-Rack-Cache to check that info. Closes #5245. Santiago Pastorino

  • Fix #5238, rendered_format is not set when template is not rendered. Piotr Sarnacki

  • Upgrade rack-cache to 1.2. José Valim

  • ActionController::SessionManagement is deprecated. Santiago Pastorino

  • Since the router holds references to many parts of the system like engines, controllers and the application itself, inspecting the route set can actually be really slow, therefore we default alias inspect to to_s. José Valim

  • Add a new line after the textarea opening tag. Closes #393 Rafael Mendonça França

  • Always pass a respond block from to responder. We should let the responder to decide what to do with the given overridden response block, and not short circuit it. sikachu

  • Fixes layout rendering regression from 3.2.2. José Valim

Rails 3.2.2 (March 1, 2012)

  • Format lookup for partials is derived from the format in which the template is being rendered. Closes #5025 part 2 Santiago Pastorino

  • Use the right format when a partial is missing. Closes #5025. Santiago Pastorino

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

  • check_box helper with :disabled => true will generate a disabled hidden field to conform with the HTML convention where disabled fields are not submitted with the form. This is a behavior change, previously the hidden tag had a value of the disabled checkbox. Tadas Tamosauskas

Rails 3.2.1 (January 26, 2012)

  • Documentation improvements.

  • Allow form.selectto accept ranges (regression). Jeremy Walker

  • datetime_selectworks with -/+ infinity dates. Joe Van Dyk

Rails 3.2.0 (January 20, 2012)

  • Setting config.assets.logger to false turn off Sprockets logger Guillermo Iguaran

  • Add config.action_dispatch.default_charsetto configure default charset for ActionDispatch::Response. Carlos Antonio da Silva

  • Deprecate setting default charset at controller level, use the new config.action_dispatch.default_charsetinstead. Carlos Antonio da Silva

  • Deprecate ActionController::UnknownAction in favour of AbstractController::ActionNotFound. Carlos Antonio da Silva

  • Deprecate ActionController::DoubleRenderError in favour of AbstractController::DoubleRenderError. Carlos Antonio da Silva

  • Deprecate method_missing handling for not found actions, use action_missing instead. Carlos Antonio da Silva

  • Deprecate ActionController#rescue_action, ActionController#initialize_template_class, and ActionController#assign_shortcuts. These methods were not being used internally anymore and are going to be removed in Rails 4. Carlos Antonio da Silva

  • Add config.assets.logger to configure Sprockets logger Rafael França

  • Use a BodyProxy instead of including a Module that responds to close. Closes #4441 if Active Record is disabled assets are delivered correctly Santiago Pastorino

  • Rails initialization with initialize_on_precompile = false should set assets_dir Santiago Pastorino

  • Add font_path helper method Santiago Pastorino

  • Depends on rack ~> 1.4.0 Santiago Pastorino

  • Add :gzip option to caches_page. The default option can be configured globally using page_cache_compression Andrey Sitnik

  • 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. José Valim

  • Add button_tagsupport to ActionView::Helpers::FormBuilder.

    This support mimics the default behavior of submit_tag.


    <%= 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 ISO8601-style dates such as '2011-08-01'. Lennart Fridén and Kim Persson

  • 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 DHH

  • Deprecated implied layout lookup in controllers whose parent had a explicit layout set:

    class ApplicationController
      layout "application"
    class PostsController < ApplicationController

    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. José Valim

  • Rails will now use your default layout (such as “layouts/application”) when you specify a layout with :onlyand :except condition, and those conditions fail. Prem Sichanugrist

    For example, consider this snippet:

    class CarsController
      layout 'single_car', :only => :show

    Rails will use 'layouts/single_car' when a request comes in :showaction, and use 'layouts/application' (or 'layouts/cars', if exists) when a request comes in for any other actions.

  • form_for with :asoption uses "#{action}_#{as}" as css class and id:


    form_for(@user, :as => 'client') # => "<form class="client_new">..."


    form_for(@user, :as => 'client') # => "<form class="new_client">..."

    Vasiliy Ermolovich

  • Allow rescue responses to be configured through a railtie as in config.action_dispatch.rescue_responses. Please look at ActiveRecord::Railtie for an example José Valim

  • Allow fresh_when/stale? to take a record instead of an options hash DHH

  • Assets should use the request protocol by default or default to relative if no request is available Jonathan del Strother

  • Log “Filter chain halted as CALLBACKNAME rendered or redirected” every time a before callback halts José Valim

  • 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 generate HTML id. Vasiliy Ermolovich


    <%= form_for(@offer, :namespace => 'namespace') do |f| %>
      <%= f.label :version, 'Version' %>:
      <%= f.text_field :version %>
    <% end %>
  • Refactor ActionDispatch::ShowExceptions. The controller is responsible for choosing to show exceptions when consider_all_requests_localis false.

    It's possible to override show_detailed_exceptions?in controllers to specify which requests should provide debugging information on errors. The default value is now false, meaning local requests in production will no longer show the detailed exceptions page unless show_detailed_exceptions?is overridden and set to request.local?.

  • Responders now return 204 No Content for API requests without a response body (as in the new scaffold) José Valim

  • 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 DHH

  • Limit the number of options for select_year to 1000.

    Pass the :max_years_allowed option to set your own limit.

    Libo Cannici

  • Passing formats or handlers to render :template and friends is deprecated. For example: Nick Sutterer & José Valim

    render :template => "foo.html.erb"

    Instead, you can provide :handlers and :formats directly as option: render :template => “foo”, :formats => [:html, :js], :handlers => :erb

  • Changed log level of warning for missing CSRF token from :debug to :warn. Mike Dillon

  • content_tag_for and div_for can now take the collection of records. It will also yield the record as the first argument if you set a receiving argument in your block Prem Sichanugrist

    So instead of having to do this:

    @items.each do |item|
      content_tag_for(:li, item) do
         Title: <%= item.title %>

    You can now do this:

    content_tag_for(:li, @items) do |item|
      Title: <%= item.title %>
  • send_file now guess the mime type Esad Hajdarevic

  • Mime type entries for PDF, ZIP and other formats were added Esad Hajdarevic

  • Generate hidden input before select with :multiple option set to true. This is useful when you rely on the fact that when no options is set, the state of select will be sent to rails application. Without hidden field nothing is sent according to HTML spec Bogdan Gusiev

  • Refactor ActionController::TestCase cookies Andrew White

    Assigning cookies for test cases should now use cookies[], e.g:

    cookies[:email] = 'user@example.com'
    get :index
    assert_equal 'user@example.com', cookies[:email]

    To clear the cookies, use clear, e.g:

    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.

  • 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.

Please check 3-1-stable for previous changes.
