Take a look at a more recent post from Mark R J: http://www.ruby-forum.com/topic/168650 He shows how you can use validates_presence_of with assocations when building a new object. ie u.books.build(:title => 'The Comedy of Errors', :author => u) where u is an unsaved User object (used as an author). I can't remember your example exactly, but that might work for you with your current validations. The way the (online) docs are worded, though, suggests that the AR-people intended it to be used more for foreign key fields than the associations based on them. The callback before_destroy I mentioned was just a thought about how you might stop an olive oil source from being 'destroyed' ('delete' won't invoke callbacks) if it happens to be the only source for an olive oil object. Anyway, you have a bunch of validations and callbacks to use to achieve whatever you need to do. -- Daniel Bush -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
