Like `format.any`, you can do the same with variants.
It works for both inline:
respond_to do |format|
format.html.any { render text: "any" }
format.html.phone { render text: "phone" }
end
and block syntax:
respond_to do |format|
format.html do |variant|
variant.any(:tablet, :phablet){ render text: "any" }
variant.phone { render text: "phone" }
end
end

TLDR: always return an object that responds to the query methods from
request.format, and do not touch Mime::Type[] lookup to avoid bugs.
---
Long version:
The initial issue was about being able to do checks like
request.format.html? for request with an unknown format, where
request.format would be nil.
This is where the issue came from at first in #7837 and #8085
(merged in cba05887dc3b56a46a9fe2779b6b228880b49622), but the
implementation went down the path of adding this to the mime type
lookup logic.
This unfortunately introduced subtle bugs, for instance in the merged
commit a test related to send_file had to be changed to accomodate the
introduction of the NullType.
Later another bug was found in #13064, related to the content-type being
shown as #<Mime::NullType:...> for templates with localized extensions
but no format included. This one was fixed in #13133, merged in
43962d6ec50f918c9970bd3cd4b6ee5c7f7426ed.
Besides that, custom handlers were not receiving the proper template
formats anymore when passing through the rendering process, because of
the NullType addition. That was found while migrating an application
from 3.2 to 4.0 that uses the Markerb gem (a custom handler that
generates both text and html emails from a markdown template).
---
This changes the implementation moving away from returning this null
object from the mime lookup, and still fixes the initial issue where
request.format.zomg? would raise an exception for unknown formats due to
request.format being nil.

AC::Parameters#fetch was refactored in 7171111 to prevent self mutation, but
in doing so it hardcodes logic #convert_hashes_to_parameters is supposed to
encapsulate.
Better leave the delegation, and add a way to avoid mutating self in there.

In most cases, when setting variant specific code, you're not sharing any code
within format.
Inline syntax can vastly simplify defining variants in those situations:
respond_to do |format|
format.js { render "trash" }
format.html do |variant|
variant.phone { redirect_to progress_path }
variant.none { render "trash" }
end
end
Becomes:
respond_to do |format|
format.js { render "trash" }
format.html.phone { redirect_to progress_path }
format.html.none { render "trash" }
end

@responses hash needs to be initialized with mime types that we get from
Collector#collect_mimes_from_class_level. Mime::Type class as key and nil as
value. This need to happen before content negotiation. Before that, it was
looping though mime types and executing mime-type-generated method inside
collector (see
AbstractController::Collector#generate_method_for_mime). That approach resulted
in 2 unnecessary method calls for each mime type
collected by Collector#collect_mimes_from_class_level.
Now hash is initialized in place, without usage of Collector#custom method.

By default, variants in the templates will be picked up if a variant is set
and there's a match. The format will be:
app/views/projects/show.html.erb
app/views/projects/show.html+tablet.erb
app/views/projects/show.html+phone.erb
If request.variant = :tablet is set, we'll automatically be rendering the
html+tablet template.
In the controller, we can also tailer to the variants with this syntax:
class ProjectsController < ActionController::Base
def show
respond_to do |format|
format.html do |html|
@stars = @project.stars
html.tablet { @notifications = @project.notifications }
html.phone { @chat_heads = @project.chat_heads }
end
format.js
format.atom
end
end
end
The variant itself is nil by default, but can be set in before filters, like
so:
class ApplicationController < ActionController::Base
before_action do
if request.user_agent =~ /iPad/
request.variant = :tablet
end
end
end
This is modeled loosely on custom mime types, but it's specifically not
intended to be used together. If you're going to make a custom mime type,
you don't need a variant. Variants are for variations on a single mime
types.

This PR fixes #13064 regression bug introduced by the #8085
Now in _process_format when the format is a Mime::NullType nothing is written in self.content_type.
In this way the method Response#assign_default_content_type_and_charset can
write the the default mime_type.

Change ActionController::Parameters#require behavior when value is empty
|
| | |
| | |
| | |
| | |
| | | |
When the value for the required key is empty an ActionController::ParameterMissing is raised which gets caught by ActionController::Base and turned into a 400 Bad Request reply with a message in the body saying the key is missing, which is misleading.
With these changes, ActionController::EmptyParameter will be raised which ActionController::Base will catch and turn into a 400 Bad Request reply with a message in the body saying the key value is empty.
