User hierarchy

I'm trying to figure out how to have a two level user relationship.

Photographers have clients. Clients have one photographer. Both are Users.

So I've got a User model that looks like this:

Just had to swap the foreign keys

has_many :client_associations,     :foreign_key => 'photographer_id',     :class_name => 'Association',     :dependent => :destroy

  has_many :clients, :through => :client_associations

  has_one :photographer_association,     :foreign_key => 'client_id',     :class_name => 'Association',     :dependent => :destroy

  has_one :photographer, :through => :photographer_association
