This mailing list (rubyonrails-core) is intended for discussion about development of the framework itself, not usage of it.
For support issues or usage questions like this one that are not issues with Rails itself, please post to the rubyonrails-talk mailing list ( http://groups.google.com/group/rubyonrails-talk) or somewhere like StackOverflow using the `ruby-on-rails` tag ( http://stackoverflow.com/questions/tagged/ruby-on-rails). You can also drop in to the #rubyonrails channel on irc.freenode.net for realtime help. You'll be more likely to get a quick answer using one of those options.
