single table inheritance , how to alias the id key name ?

rubyonrails-talk
#1

I have a model class Person < ActiveRecord::Base
and 2 classes inheriting from it
class User < Person and class Contact < Person

obviously the id is person.id
but is there anyway to use user.id and contact.id or should I
always use person.id ???

thanks for your suggestions

Your question doesn't really make a huge amount of sent. If foo is an instance of person, user, contact (or any other AR model for that matter) the foo.id gives you the primary key
