## Rails 4.0.0 (unreleased) ##
* `BestStandardsSupport` no longer duplicates `X-UA-Compatible` values on
each request to prevent header size from blowing up.
*Edward Anderson*
* 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.
Fix #7979
*André Arko*, *Steve Klabnik*, *Alexey Gaziev*
* Do not append second slash to `root_url` when using `trailing_slash: true`
Fix #8700
Example:
# before
root_url # => http://test.host//
# after
root_url # => 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.
Fix #8661.
*Yves Senn*
* Added `Mime::NullType` class. This allows to use html?, xml?, json?..etc when
the `format` of `request` is unknown, without raise 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 %>
All the topics on this project
<%= render project.topics %>
<% end %>
# and
<%= cache_unless condition, project do %>
All the topics on this project
<%= render project.topics %>
<% end %>
*Stephen Ausman + Fabrizio Regini + Angelo Capilleri*
* Add filter capability to ActionController logs for redirect locations:
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.
#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.
Fix #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`.
Fix #7976.
*Joost Baaij*
* Fix input name when `multiple: true` and `:index` are set.
Before:
check_box("post", "comment_ids", { multiple: true, index: "foo" }, 1)
#=>
After:
check_box("post", "comment_ids", { multiple: true, index: "foo" }, 1)
#=>
Fix #8108.
*Daniel Fox, Grant Hutchins & Trace Wax*
* `BestStandardsSupport` middleware now appends it's `X-UA-Compatible` value to app's
returned value if any.
Fix #8086.
*Nikita Afanasenko*
* `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
Fix #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
Fix #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*
* Remove `rack-cache` dependency from Action Pack and declare it on Gemfile
*Guillermo Iguaran*
* Rename internal variables on `ActionController::TemplateAssertions` to prevent
naming collisions. `@partials`, `@templates` and `@layouts` are now prefixed with an underscore.
Fix #7459.
*Yves Senn*
* `resource` and `resources` don'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-.css and aliases phone/index.css to phone.css.
config.assets.precompile = [ 'phone.css' ]
# Precompiles phone/index-.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.
Fix #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. As side effect the autoloading of unloaded classes objects
saved as values in session isn't supported anymore when mem_cache session store is
used, this can have an impact in apps only when config.cache_classes is false.
*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 <%= @user.name %>
<% end %>
# => ""
*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
when you are going to reference this asset from external host. *Prem Sichanugrist*
* Default responder will now always use your overridden block in `respond_with` to render your response. *Prem Sichanugrist*
* Allow `value_method` and `text_method` arguments from `collection_select` and
`options_from_collection_for_select` to 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_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:
The label/check_box pairs can be customized with a block.
*Carlos Antonio da Silva + Rafael Mendonça França*
* Add `collection_radio_buttons` form helper, similar to `collection_select`:
Example:
collection_radio_buttons :post, :author_id, Author.all, :id, :name
# Outputs something like:
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`
attribute to the hidden field as well. *Carlos Antonio da Silva*
* Turn off verbose mode of rack-cache, we still have X-Rack-Cache to
check that info. Closes #5245. *Santiago Pastorino*
* `label` form helper accepts `for: nil` to not generate the attribute. *Carlos Antonio da Silva*
* Add `:format` option to `number_to_percentage`. *Rodrigo Flores*
* Add `config.action_view.logger` to configure logger for Action View. *Rafael Mendonça França*
* Deprecated `ActionController::Integration` in favour of `ActionDispatch::Integration`.
* Deprecated `ActionController::IntegrationTest` in favour of `ActionDispatch::IntegrationTest`.
* Deprecated `ActionController::PerformanceTest` in favour of `ActionDispatch::PerformanceTest`.
* Deprecated `ActionController::AbstractRequest` in favour of `ActionDispatch::Request`.
* Deprecated `ActionController::Request` in favour of `ActionDispatch::Request`.
