I'm having trouble with this model: class Person < AR::B belongs_to :shipping_address, :class_name => 'Address' belongs_to :billing_address, :class_name => 'Address' end
class Address < AR::B end The problem is that I want Address to be a Value Object (as in DDD), and if I do this: p = Person.create :shipping_address => Address.new(...) and later I change the address: p.shipping_address = Address.new(...) p.save the first address object doesn't get deleted from the DB. It becomes an orphan. I can inverse the association and use a has_one but then I have to put two foreign keys in the address table... and that could be a problem because there are other models that have addresses. Another option could be to model both associations as composed_of but then I have to put all of the address table columns on the people table, and repeat this on the other models that have addresses too. How can I solve this? Any suggestions?
