I have a virtual attribute ''tags'' , and defined a setter method for it tags=(val). My setter method is not called while creating a Article. I copied my rails 3.2.11 code in rails 4, it was perfectly working in former. I want to know who can i use setter method for virtual attribute in rails 4. Or is it a bug in rails 4. I raised this as a issue in rails<https://github.com/rails/rails/issues/10282>project -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
