Poking around books & blogs about association proxies, and experimenting, but I can't seem to come across the right combination for this one particular task.
I'm assuming there's a way to get the "user_type" attribute from within the UserFilter using the belongs_to association?
class PrivilegedUser < ActiveRecord::Base
# has an attribute named user_type
class UserFilter < ActiveRecord::Base
x = self.privileged_user.user_type <------ ???
The example above gives me undefined method errors.
