If you try to run style 2 without X and Y having been created you will get "NameError: uninitialized constant X". The difference between class and module in Ruby is fairly minimal (and mainly used for inferring a difference in usage to the reader) Cheers, Andy -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

ok as far as controllers are concerned in a RoR app would either of those style matter as far as name spacing?

But if you have this: class Admin::FooController end without declaring Admin first you''ll get an error. What I tend to do is this: module Admin class BaseController def some_admin_method ... end end end Because you need to declare Admin before you can just randomly start using it. Then I do this when declaring a subclass: class PagesController < Admin::BaseController ... end Cheers, Andy -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
