Hi, I wonder if anyone has any suggestions for solving the following issue. I just upgraded from rails 3.2.x to 4.0.3 The following was working in 3.2.x def show @question = Question.find(params[:id]) session[:question_id] = @question.id @pictures = @question.pictures Now however, I get the error: uninitialized constant Question::Picture (for the line @pictures @question.pictures) I have a join table "pictures_questions" and as I said this was working prior to the upgrade. Any ideas? Thanks, Dave -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
