In addition if A has_one C then you can say A has_one b through C and then you can say @a.b, or if A belongs_to C then you use delegate so that again you can say @a.b. There is no advantage at run time to these but they may make your code simpler. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
