Hello, I have a User model as illustrated below:

class User < ActiveRecord
  belongs_to :college
  belongs_to :class_level
end

I want to ALWAYS join with those other two tables returning one simplified User object. How do I accomplish this in my User model. I'm aware that I can do this in another model:

class Foo < ActiveRecord
  has_many :users, :include => [:college, :class_level]
end

But I want to do this in my User model, so Foo.users will either be eager loaded OR be joined already. Is there a way to create an initialize this in the User model?
