* 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 additonal
payload data is not available.
See:
* #14903
* https://github.com/roidrage/lograge/issues/37
*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.
*Andrew White*, *Tatiana Soukiassian*
