I made a patch for a bug that I found in AR: https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/5125-collection_singular_ids-method-raises-an-exception-when-primary_key-is-string-rails-3 I''m looking for some people to review it. It is a very simple patch with tests included. I hope you can find time for it. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
