Are these two below the same thing?
1. module X module Y class Z
2. class X::Y::Z
Providing class Z has already been created with style 1, yes.
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)

ok as far as controllers are concerned in a RoR app would either of those style matter as far as name spacing?
Nope, won’t matter a jot.
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

OK, that is what I thought, thanks.
