In my model, if I have a field, that contains the id to another table, twice 
(like, primary associate and a secondary associate) I am specifying this as

class Customer < ActiveRecord::Base
    belongs_to: associate :foreign_key => "associatekey1"
    belongs_to: associate :foreign_key => "associatekey2"
end

This doesn't work -- but my question is how SHOULD the syntax for specifying 
this look? Thanks, Ike
