From 7dcd0d7d967c613f4e447ba6330e1f616b93c1a3 Mon Sep 17 00:00:00 2001 From: David Heinemeier Hansson Date: Fri, 29 Feb 2008 18:09:23 +0000 Subject: Added that requests with JavaScript as the priority mime type in the accept header and no format extension in the parameters will be treated as though their format was :js when it comes to determining which template to render. This makes it possible for JS requests to automatically render action.js.rjs files without an explicit respond_to block [DHH] git-svn-id: http://svn-commit.rubyonrails.org/rails/trunk@8956 5ecf4fe2-1ee6-0310-87b1-e25e094e27de --- actionpack/lib/action_view/base.rb | 23 +++++++++++++++++++++-- 1 file changed, 21 insertions(+), 2 deletions(-) (limited to 'actionpack/lib') diff --git a/actionpack/lib/action_view/base.rb b/actionpack/lib/action_view/base.rb index 9217d5ae0c..f5346bd480 100644 --- a/actionpack/lib/action_view/base.rb +++ b/actionpack/lib/action_view/base.rb @@ -344,10 +344,29 @@ If you are rendering a subtemplate, you must now use controller-like partial syn end # symbolized version of the :format parameter of the request, or :html by default. + # + # EXCEPTION: If the :format parameter is not set, the Accept header will be examined for + # whether it contains the JavaScript mime type as its first priority.
