I'm struggling with something that must be very common pattern, and
want to do it the correct rails/ruby way but am a bit dense !
I have users - an admin user, registered users and a guest user (using
For many of linked associations I want the admin to be able to list or
edit all instances, the registered user only their own one and guest
none at all.
So somehow I want to over ride or extend the associations, or find, so
that the condition is captured in one place and my controller/view
code isn't littered with these same if, else blocks...e.g something
I've tried using the Association extensions so I can simply call
@theme = User.current.theme.find_theme
class User < ActiveRecord::Base
has_one :theme do
But no joy, this gives method missing. If I change the association to
has_many however, it does work - but this is obviously not then
correct with the model.
Do extensions only work for has_many ?
Any advice on best place or pattern to encapsulate this kind of
situation much appreciated.
