Hi Rick, Thanks for looking at the links and thanks for the clarifications. I missed your Color class association so that part is fine. Looking at the Customer - Order association you placed here.. Customer --> Has Many --> Orders Orders --> Belongs to --> Customer That's a correct association... Now look at yours: Person --> Has Many --> Addresses Address --> Belongs to --> (PRODUCT)? Notice there's no correct association here... Anytime you you have a name_id in any of your tables, rails automatically knows it's a foreign key once you apply the association. Person has many addresses Address belongs to person Product has many addresses Address belongs to product That sound about right? Class Person has_many :addresses, :dependent => :destroy end Class Address belongs_to :person belongs_to :product end Class Product has_many :addresses end -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
