From ed88a601f7b37de0f89b64249aaeed884faed836 Mon Sep 17 00:00:00 2001 From: Prem Sichanugrist Date: Fri, 28 Feb 2014 19:39:22 -0500 Subject: [PATCH] Do note remove `Content-Type` when `render :body` `render :body` should just not set the `Content-Type` header. By removing the header, it breaks the compatibility with other parts. After this commit, `render :body` will returns `text/html` content type, sets by default from `ActionDispatch::Response`, and it will preserve the overridden content type if you override it. Fixes #14197, #14238 This partially reverts commit 3047376870d4a7adc7ff15c3cb4852e073c8f1da. --- .../metal/rack_delegation.rb | 4 +-- .../lib/action_controller/metal/rendering.rb | 4 +-- .../lib/action_dispatch/http/response.rb | 13 +-------- .../controller/new_base/render_body_test.rb | 29 ++++++++----------- actionpack/test/dispatch/response_test.rb | 8 ----- .../action_view/helpers/rendering_helper.rb | 5 ++-- actionview/lib/action_view/rendering.rb | 5 ---- guides/source/layouts_and_rendering.md | 7 +++-- 8 files changed, 24 insertions(+), 51 deletions(-) diff --git a/actionpack/lib/action_controller/metal/rack_delegation.rb b/actionpack/lib/action_controller/metal/rack_delegation.rb index e1bee9e60c..bdf6e88699 100644 --- a/actionpack/lib/action_controller/metal/rack_delegation.rb +++ b/actionpack/lib/action_controller/metal/rack_delegation.rb @@ -5,8 +5,8 @@ module ActionController module RackDelegation extend ActiveSupport::Concern - delegate :headers, :status=, :location=, :content_type=, :no_content_type=, - :status, :location, :content_type, :no_content_type, :to => "@_response" + delegate :headers, :status=, :location=, :content_type=, + :status, :location, :content_type, :to => "@_response" def dispatch(action, request) set_response!(request) diff --git a/actionpack/lib/action_controller/metal/rendering.rb b/actionpack/lib/action_controller/metal/rendering.rb index 3c4ef596c7..93e7d6954c 100644 --- a/actionpack/lib/action_controller/metal/rendering.rb +++ b/actionpack/lib/action_controller/metal/rendering.rb @@ -45,9 +45,7 @@ module ActionController def _process_format(format, options = {}) super - if options[:body] - self.headers.delete "Content-Type" - elsif options[:plain] + if options[:plain] self.content_type = Mime::TEXT else self.content_type ||= format.to_s diff --git a/actionpack/lib/action_dispatch/http/response.rb b/actionpack/lib/action_dispatch/http/response.rb index f14ca1ea44..2c6bcf7b7b 100644 --- a/actionpack/lib/action_dispatch/http/response.rb +++ b/actionpack/lib/action_dispatch/http/response.rb @@ -63,8 +63,6 @@ module ActionDispatch # :nodoc: # content you're giving them, so we need to send that along. attr_accessor :charset - attr_accessor :no_content_type # :nodoc: - CONTENT_TYPE = "Content-Type".freeze SET_COOKIE = "Set-Cookie".freeze LOCATION = "Location".freeze @@ -305,17 +303,8 @@ module ActionDispatch # :nodoc: !@sending_file && @charset != false end - def remove_content_type!
