Hello, I have the following class hierarchy Attachment < Image < SpecialImage . An Attachment should be a plain attachment (anything should be allowed) where an Image should be an image (obviously ;) ). SpecialImage is a special Image with additional metadata. I modeled this using single table inheritance, and am now wondering about the correct usage of has_attachment in the models. Should I call has_attachment in all the three model classes? If so, then with what parameters? Or should I modify self.attachement_options (the attachment_fu options hash) in the subclasses? Thanks for your help, Gormo -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
