When looking at comments which will be made on different types (say post, picture, article) I see a lot of advice towards using polymorphic associations for this. Ryan Bates has a good railscast on it:
http://railscasts.com/episodes/154-polymorphic-association-revised However, I'm not sure I see why this is such a good idea in this case. Would it not make more sense to have multiple comment types: PostComment < Comment PictureComment < Comment etc. Now we have the same amount of comment rows and we maintain referential integrity, although we do now have more tables.. Can someone point me in the direction of why polymorphic associations are the way to go rather than using inheritance and multiple tables in the db? Does it make much difference? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
