I know what polymorphism is but none of the examples made sense until I saw yours! In my case, I have an item that has an owner, but the owner can be of differing types (Employee, Department, etc.). Thanks! Holy crap - your blog post was the first to make sense to me! I know what polymorphism is but none of the examples made sense until I saw yours!

I was wondering how to delete a message from say a BuyerProfile object? e.g. bp = BuyerProfile.find :first bp.messages.count # outputs 2 bp.messages.first.destroy Destroy should delete the first message, but it won't do so. Any reason wjy? Great post. I was wondering how to delete a message from say a BuyerProfile object?
