rails--rails/actionpack/CHANGELOG.md

• Add ActionController::Renderer to render arbitrary templates outside controller actions.

  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

  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.
