## Rails 5.0.0.beta2 (February 01, 2016) ##
* Add `-g` and `-c` (short for _grep_ and _controller_ respectively) options
to `bin/rake routes`. These options return the url `name`, `verb` and
`path` field that match the pattern or match a specific controller.
Deprecate `CONTROLLER` env variable in `bin/rake routes`.
See #18902.
*Anton Davydov* & *Vipul A M*
* Response etags to always be weak: Prefixes 'W/' to value returned by
`ActionDispatch::Http::Cache::Response#etag=`, such that etags set in
`fresh_when` and `stale?` are weak.
Fixes #17556.
*Abhishek Yadav*
* Provide the name of HTTP Status code in assertions.
*Sean Collins*
* More explicit error message when running `rake routes`. `CONTROLLER` argument
can now be supplied in different ways:
`Rails::WelcomeController`, `Rails::Welcome`, `rails/welcome`.
Fixes #22918.
*Edouard Chin*
* Allow `ActionController::Parameters` instances as an argument to URL
helper methods. An `ArgumentError` will be raised if the passed parameters
are not secure.
Fixes #22832.
*Prathamesh Sonpatki*
* Add option for per-form CSRF tokens.
*Greg Ose & Ben Toews*
* Add tests and documentation for `ActionController::Renderers::use_renderers`.
*Benjamin Fleischer*
* Fix `ActionController::Parameters#convert_parameters_to_hashes` to return filtered
or unfiltered values based on from where it is called, `to_h` or `to_unsafe_h`
respectively.
Fixes #22841.
*Prathamesh Sonpatki*
* Add `ActionController::Parameters#include?`
*Justin Coyne*
## Rails 5.0.0.beta1 (December 18, 2015) ##
* Deprecate `redirect_to :back` in favor of `redirect_back`, which accepts a
required `fallback_location` argument, thus eliminating the possibility of a
`RedirectBackError`.
*Derek Prior*
* Add `redirect_back` method to `ActionController::Redirecting` to provide a
way to safely redirect to the `HTTP_REFERER` if it is present, falling back
to a provided redirect otherwise.
*Derek Prior*
* `ActionController::TestCase` will be moved to it's own gem in Rails 5.1
With the speed improvements made to `ActionDispatch::IntegrationTest` we no
longer need to keep two separate code bases for testing controllers. In
Rails 5.1 `ActionController::TestCase` will be deprecated and moved into a
gem outside of Rails source.
This is a documentation deprecation so that going forward so new tests will use
`ActionDispatch::IntegrationTest` instead of `ActionController::TestCase`.
*Eileen M. Uchitelle*
* Add a `response_format` option to `ActionDispatch::DebugExceptions`
to configure the format of the response when errors occur in
development mode.
If `response_format` is `:default` the debug info will be rendered
in an HTML page. In the other hand, if the provided value is `:api`
the debug info will be rendered in the original response format.
*Jorge Bejar*
* Change the `protect_from_forgery` prepend default to `false`.
Per this comment
https://github.com/rails/rails/pull/18334#issuecomment-69234050 we want
`protect_from_forgery` to default to `prepend: false`.
`protect_from_forgery` will now be inserted into the callback chain at the
point it is called in your application. This is useful for cases where you
want to `protect_from_forgery` after you perform required authentication
callbacks or other callbacks that are required to run after forgery protection.
If you want `protect_from_forgery` callbacks to always run first, regardless of
position they are called in your application then you can add `prepend: true`
to your `protect_from_forgery` call.
Example:
```ruby
protect_from_forgery prepend: true
```
*Eileen M. Uchitelle*
* In url_for, never append a question mark to the URL when the query string
is empty anyway. (It used to do that when called like `url_for(controller:
'x', action: 'y', q: {})`.)
*Paul Grayson*
* Catch invalid UTF-8 querystring values and respond with BadRequest
Check querystring params for invalid UTF-8 characters, and raise an
ActionController::BadRequest error if present. Previously these strings
would typically trigger errors further down the stack.
*Grey Baker*
* Parse RSS/ATOM responses as XML, not HTML.
*Alexander Kaupanin*
* Show helpful message in `BadRequest` exceptions due to invalid path
parameter encodings.
Fixes #21923.
*Agis Anastasopoulos*
* Add the ability of returning arbitrary headers to `ActionDispatch::Static`.
Now ActionDispatch::Static can accept HTTP headers so that developers
will have control of returning arbitrary headers like
'Access-Control-Allow-Origin' when a response is delivered. They can be
configured with `#config`:
Example:
config.public_file_server.headers = {
"Cache-Control" => "public, max-age=60",
"Access-Control-Allow-Origin" => "http://rubyonrails.org"
}
*Yuki Nishijima*
* Allow multiple `root` routes in same scope level. Example:
Example:
root 'blog#show', constraints: ->(req) { Hostname.blog_site?(req.host) }
root 'landing#show'
*Rafael Sales*
* Fix regression in mounted engine named routes generation for app deployed to
a subdirectory. `relative_url_root` was prepended to the path twice (e.g.
"/subdir/subdir/engine_path" instead of "/subdir/engine_path")
Fixes #20920. Fixes #21459.
*Matthew Erhard*
* `ActionDispatch::Response#new` no longer applies default headers. If you want
default headers applied to the response object, then call
`ActionDispatch::Response.create`. This change only impacts people who are
directly constructing an `ActionDispatch::Response` object.
* Accessing mime types via constants like `Mime::HTML` is deprecated. Please
change code like this:
Mime::HTML
To this:
Mime[:html]
This change is so that Rails will not manage a list of constants, and fixes
an issue where if a type isn't registered you could possibly get the wrong
object.
`Mime[:html]` is available in older versions of Rails, too, so you can
safely change libraries and plugins and maintain compatibility with
multiple versions of Rails.
* `url_for` does not modify its arguments when generating polymorphic URLs.
*Bernerd Schaefer*
* Make it easier to opt in to `config.force_ssl` and `config.ssl_options` by
making them less dangerous to try and easier to disable.
SSL redirect:
* Move `:host` and `:port` options within `redirect: { … }`. Deprecate.
* Introduce `:status` and `:body` to customize the redirect response.
The 301 permanent default makes it difficult to test the redirect and
back out of it since browsers remember the 301. Test with a 302 or 307
instead, then switch to 301 once you're confident that all is well.
HTTP Strict Transport Security (HSTS):
* Shorter max-age. Shorten the default max-age from 1 year to 180 days,
the low end for https://www.ssllabs.com/ssltest/ grading and greater
than the 18-week minimum to qualify for browser preload lists.
* Disabling HSTS. Setting `hsts: false` now sets `hsts { expires: 0 }`
instead of omitting the header. Omitting does nothing to disable HSTS
since browsers hang on to your previous settings until they expire.
Sending `{ hsts: { expires: 0 }}` flushes out old browser settings and
actually disables HSTS:
http://tools.ietf.org/html/rfc6797#section-6.1.1
* HSTS Preload. Introduce `preload: true` to set the `preload` flag,
indicating that your site may be included in browser preload lists,
including Chrome, Firefox, Safari, IE11, and Edge. Submit your site:
https://hstspreload.appspot.com
*Jeremy Daer*
* Update `ActionController::TestSession#fetch` to behave more like
`ActionDispatch::Request::Session#fetch` when using non-string keys.
*Jeremy Friesen*
* Using strings or symbols for middleware class names is deprecated. Convert
things like this:
middleware.use "Foo::Bar"
to this:
middleware.use Foo::Bar
* `ActionController::TestSession` now accepts a default value as well as
a block for generating a default value based off the key provided.
This fixes calls to `session#fetch` in `ApplicationController` instances that
take more two arguments or a block from raising `ArgumentError: wrong
number of arguments (2 for 1)` when performing controller tests.
*Matthew Gerrior*
* Fix `ActionController::Parameters#fetch` overwriting `KeyError` returned by
default block.
*Jonas Schuber Erlandsson*, *Roque Pinel*
* `ActionController::Parameters` no longer inherits from
`HashWithIndifferentAccess`
Inheriting from `HashWithIndifferentAccess` allowed users to call any
enumerable methods on `Parameters` object, resulting in a risk of losing the
`permitted?` status or even getting back a pure `Hash` object instead of
a `Parameters` object with proper sanitization.
By not inheriting from `HashWithIndifferentAccess`, we are able to make
sure that all methods that are defined in `Parameters` object will return
a proper `Parameters` object with a correct `permitted?` flag.
*Prem Sichanugrist*
* Replaced `ActiveSupport::Concurrency::Latch` with `Concurrent::CountDownLatch`
from the concurrent-ruby gem.
*Jerry D'Antonio*
* Add ability to filter parameters based on parent keys.
# matches {credit_card: {code: "xxxx"}}
# doesn't match {file: { code: "xxxx"}}
config.filter_parameters += [ "credit_card.code" ]
See #13897.
*Guillaume Malette*
* Deprecate passing first parameter as `Hash` and default status code for `head` method.
*Mehmet Emin İNAÇ*
* Adds`Rack::Utils::ParameterTypeError` and `Rack::Utils::InvalidParameterError`
to the rescue_responses hash in `ExceptionWrapper` (Rack recommends
integrators serve 400s for both of these).
*Grey Baker*
* Add support for API only apps.
`ActionController::API` is added as a replacement of
`ActionController::Base` for this kind of applications.
*Santiago Pastorino*, *Jorge Bejar*
* Remove `assigns` and `assert_template`. Both methods have been extracted
into a gem at https://github.com/rails/rails-controller-testing.
See #18950.
*Alan Guo Xiang Tan*
* `FileHandler` and `Static` middleware initializers accept `index` argument
to configure the directory index file name. Defaults to `index` (as in
`index.html`).
See #20017.
*Eliot Sykes*
* Deprecate `:nothing` option for `render` method.
*Mehmet Emin İNAÇ*
* 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*
* Allow `Bearer` as token-keyword in `Authorization-Header`.
Additionally to `Token`, the keyword `Bearer` is acceptable as a keyword
for the auth-token. The `Bearer` keyword is described in the original
OAuth RFC and used in libraries like Angular-JWT.
See #19094.
*Peter Schröder*
* 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 a shortcut is given it also performs the lookup without the 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 #14903.
*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 behavior 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*
