Thank you both for your help - I got it fixed with a little help from Isaackearse on the Rails IRC channel.
The reason it was playing up was because I had some posts in the db that weren't associated to any users - once they were deleted everything works as expected :) Thanks again to everyone for their help :D -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
