The problem is that I need to insert a value in the classification_id of the join model Categorization. The table for the join model is automatically enhanced, so when I create a new Company in the categorizations table the attributes company_id and category_id are setted. I want to set also the attribute classification_id of the join table so I think I can do it only in a before_save callback and not in the company form. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
