And thanks for the links by the way. But looking at the second link they show:
class Customer < ActiveRecord::Base has_many :orders, :dependent => :destroy end class Order < ActiveRecord::Base belongs_to :customer end How is that any different than my association for Person and Address (which you said was wrong)? class Person < ActiveRecord::Base has_many :addresses, :dependent => :destroy end class Address < ActiveRecord::Base belongs_to :product end It looks the same as it does in the doc, unless I'm missing something?
