You should have a model and table that agree with each other (User and users or RegisterUser and register_users). RegisterUsers sounds a strange name for a model and table though. Usually a table maps to something in the real world (such as users). If you have a table called register_users then does each row represent a RegisterUser (whatever that is)? There need not be a controller with the same name however, so I am guessing that maybe the controller should be called register_users as that is what it does. Only you know what your app is supposed to be doing though. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
