Hello, I am new to Ruby on rails and this is therefore probably trivial. Lets say I have 3 tables - users[id,name, age, ...], interests[id,name,description, ...], and finally a table user_interests[id,user_id,interest_id] to link a user to a set of interests.

Instead of having it highlight the bad fields when you enter in a record that fails validation, is there a way to make it do an action? I''m looking for something like this: validates_uniqueness_of :user_id,:url => {:controller => "headline", :action => "index"} so that on failing the uniqueness check, it would go to the headline controller. --
