I tried to use `added?` but it seems that if the returned value is `false`, it adds the consulted attribute to the errors' hash and sets its value to an empty array. This produces an error (at least in my case) `RuntimeError: can't add a new key into hash during iteration`. Do you know the why of this behaviour?
