This method was only used in the Rails tests and not by other methods in
the Rails simulator. Because it's a no-doc'd class it should be safe to
remove without deprecation.
When the path info is read from the socket it's encoded as ASCII 8BIT.
The unescape method changes the encoding to UTF8 but it should maintain
the encoding of the string that's passed in.
This causes parameters to be force encoded to UTF8 when we don't
actually know what the encoding of the parameter should be.
In order to fully support the same interface as `Hash#delete`, we need
to pass the block through to the underlying method, not just the key.
This used to work correctly, but it regressed when
`ActionController::Parameters` stopped inheriting from `Hash` in 5.0.
Follow up of 03d3f036.
Some of `respond_to?` were replaced to `respond_to_missing?` in 03d3f036.
But the visibility is still public. It should be private.
We are talking about a list of parameters even so we need to use plural.
Even if we were talking about the instance of the Parameters object we
would have to use the capital and monospaced font.
Previously it was raising an error because it may be unsafe to use those
methods in a unpermitted parameter. Now we delegate to to_h that already
raise an error when the Parameters instance is not permitted.
This also fix a bug when using `#to_query` in a hash that contains a
`ActionController::Parameters` instance and was returning the name of the
class in the string.
Now methods that implicit convert objects to a hash will be able to work
without requiring the users to change their implementation.
This method will return a Hash instead of a HashWithIndefirentAccess
to mimic the same implementation of HashWithIndefirentAccess#to_hash.
Before we returned either an empty hash or only the always permitted
parameters (:controller and :action by default).
The previous behavior was dangerous because in order to get the
attributes users usually fallback to use to_unsafe_h that could
potentially introduce security issues.
The to_unsafe_h API is also not good since Parameters is a object that
quacks like a Hash but not in all cases since to_h would return an empty
hash and users were forced to check if to_unsafe_h is defined or if the
instance is a ActionController::Parameters in order to work with it.
This end up coupling a lot of libraries and parts of the application
with something that is from the controller layer.
The current check for whether to add an optional format to the path
is very lax and will match things like `:format_id` where there are
nested resources, e.g:
resources :formats do
resources :items
end
Fix this by using a more restrictive regex pattern that looks for
the patterns `(.:format)`, `.:format` or `/` at the end of the path.
Note that we need to allow for multiple closing parenthesis since
the route may be of this form:
get "/books(/:action(.:format))", controller: "books"
This probably isn't what's intended since it means that the default
index action route doesn't support a format but we have a test for
it so we need to allow it.
Fixes#28517.
Effectively treat nil values as "auto", e.g. whatever a form helper
chooses to interpret it as.
But treat an explicitly assigned false value as disabling.
I came up against this while dealing with a misconfigured server. The
browser was setting the Origin header to "https://example.com", but the
Rails app returned "http://example.com" from request.base_url (because
it was failing to detect that HTTPS was used).
This caused verify_authenticity_token to fail, but the message in the
log was "Can't verify CSRF token", which is confusing because the
failure had nothing to do with the CSRF token sent in the request. This
made it very hard to identify the issue, so hopefully this will make it
more obvious for the next person.
In Rails 4.2, `ActionController::Metal` controllers did not include the
default headers from `ActionDispatch::Response`. However, through e16afe6, and a
general shift towards having `ActionController::Metal` objects contain
`ActionDispatch::Response` objects (instead of just returning an array
of status, headers, and body), this behavior was lost. This PR helps to
restore the original behavior by having `ActionController::Metal`
controllers generate Response objects without the default headers, while
`ActionController::Base` now overrides the factory method to make sure
its version does have the default headers.
In the context of controller parameters, reverse_merge is commonly used
to provide defaults for user input. Having an alias to reverse_merge
called with_defaults feels more idiomatic for Rails.
Sometimes we want to use rack_test partially instead of selenium for test speed:
```ruby
class ApplicationSystemTestCase < ActionDispatch::SystemTestCase
driven_by :selenium, using: :chrome, screen_size: [1400, 1400], options: {url: "http://chrome:4444/wd/hub"}
end
class WithJavaScriptTest < ApplicationSystemTestCase
end
class WithoutJavaScriptTest < ApplicationSystemTestCase
driven_by :rack_test
end
```
In the abobe case, `WithoutJavaScriptTest` uses selenium because
`SystemTestCase` calls superclass' driver on `#initialize` (`self.class.superclass.driver.use`).
Using `class_attribute` can handle inherited `driven_by`.
