Comments on: Multi Model Forms & Validations in Ruby on Rails http://jimneath.org/2008/09/06/multi-model-forms-validations-in-ruby-on-rails/ Ruby on Rails, Javascript, CSS and Standards Tue, 06 Jan 2009 02:28:06 +0000 http://wordpress.org/?v=2.7 hourly 1 By: Pepe Gonzales http://jimneath.org/2008/09/06/multi-model-forms-validations-in-ruby-on-rails/comment-page-1/#comment-714 Pepe Gonzales Thu, 06 Nov 2008 19:45:44 +0000 http://jimneath.org/?p=55#comment-714 Question... If all the save! calls are wrapped with a transaction, is running valid? on all models necessary? I thought that if, for example, @dog isn't valid, the save! call will throw an exception, and the whole transaction will be undone (ie. @person and @cat will be destroyed). Am I wrong? Question…

Glad I'm not the only one drinking the kool aid.

It's a technique written by Ryan Bates. You can go check it 'em up too. There’s also another way in the Advanced Rails Recipe book for handling multiple-model in one form.

I don't see any alternative to update_attributes that doesn't save the record... Is there a nice way to do the same thing for the update method as well as create?

I didn't actually know you could do half the stuff proposed in the these comments, so thanks guys. I'll update the article later on today so reflect everything you chaps have said.
