It's easy. I don't have any code close at hand, but it's pretty straightforward -- stick the validation URL in an attribute you can access then use that. Just remember to have your authenticity certificate as part of the post data so Rails doesn't suspect a forgery. Marnen's right, you shouldn't rely completely on client-side validation, but I typically do as much validation as possible on the client to avoid beating up the server and/or spoiling the client experience, then validate everything completely on the server to prevent attacks or mis-entries on the part of people who have disabled js. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
