From 7611fa6d469cef9accabe6bb5e7e95914756322a Mon Sep 17 00:00:00 2001 From: David Heinemeier Hansson Date: Sat, 2 Dec 2006 23:07:04 +0000 Subject: Added Request#format to return the format used for the request as a mime type. If no format is specified, the first Request#accepts type is used. This means you can stop using respond_to for anything else than responses [DHH] git-svn-id: http://svn-commit.rubyonrails.org/rails/trunk@5664 5ecf4fe2-1ee6-0310-87b1-e25e094e27de --- actionpack/lib/action_controller/mime_type.rb | 4 ++++ actionpack/lib/action_controller/request.rb | 10 ++++++++++ 2 files changed, 14 insertions(+) (limited to 'actionpack/lib/action_controller') diff --git a/actionpack/lib/action_controller/mime_type.rb b/actionpack/lib/action_controller/mime_type.rb index e57339b3aa..9c4fe63ab0 100644 --- a/actionpack/lib/action_controller/mime_type.rb +++ b/actionpack/lib/action_controller/mime_type.rb @@ -48,6 +48,10 @@ module Mime LOOKUP[string] end + def lookup_by_extension(extension) + EXTENSION_LOOKUP[extension] + end + def register(string, symbol, mime_type_synonyms = [], extension_synonyms = []) Mime.send :const_set, symbol.to_s.upcase, Type.new(string, symbol, mime_type_synonyms) diff --git a/actionpack/lib/action_controller/request.rb b/actionpack/lib/action_controller/request.rb index 98d28d24b8..8c21adb8df 100755 --- a/actionpack/lib/action_controller/request.rb +++ b/actionpack/lib/action_controller/request.rb @@ -83,6 +83,16 @@ module ActionController end end + # Returns the Mime type for the format used in the request.
