Rails - Sep 2005 - Table relationships with single table inheritance

Hi,

How do I relate a table to another when one of the models uses single table
inheritance? Will this even work? This is the specific problem I am having:

There''s an "Address" model with "ShippingAddress"
and "BillingAddress" as
subclasses. It looks like this:

class Address < ActiveRecord::Base
End

class ShippingAddress < Address
   has_one :order
End

Class BillingAddress < Address
End


On the Order side:

class order < ActiveRecord::Base
  belongs_to :ShippingAddress??? Or shipping_address??
End
