Fixing multipart POST in Rails

Our API is REST based, and so we need all the REST verbs to work. Unfortunately Rails doesn't work correctly with multipart PUT submits. The fix is very simple, and it's a one line change in the file actionpack/lib/action_controller/cgi_ext/raw_post_data_fix.rb:

--- actionpack/lib/action_controller/cgi_ext/raw_post_data_fix.rb       (revision 4380)
+++ actionpack/lib/action_controller/cgi_ext/raw_post_data_fix.rb       (working copy)
@@ -15,7 +15,7 @@
         method = :get
       end

-      if method == :post && (boundary = multipart_form_boundary)
+      if ((method == :post) || (method == :put)) && (boundary = multipart_form_boundary)
         @multipart = true
         @params = read_multipart(boundary, Integer(env_table['CONTENT_LENGTH']))
       else

The only change is adding the :put method to the if that makes the params into multiparams.

I'm posting this as a bug with the patch and the related tests to the Rail trac. Hopefuly it'll be included in a coming release of Rails.
