I have two models Club and users. users are regular authenticated users and some of them might create a club. A club can also have members (essentially users) and there are attributes and models that apply to member but not to users. Here is what I have right now.

Hi ruby community, It has been months after much experimenting RubyOnRail but it wasn''t chosen for my Enterprise project. Recently, I heard some of my friends argue that RubyOnRail is Enterprise-class framework which perform much better than PHP.

Hey everyone! I have a problem that''s been making me a little nuts. I would like to use RoR for a upcoming project, but if I can''t get past this hiccup I''m afraid I''ll have to use PHP or Java.
