Noam, check out the registration cogbin. It goes:
class UniqueUsername(validators.FancyValidator):
"Validator to confirm that a given user_name is unique."
messages = {'notUnique': 'That user name is already being used.'}
def _to_python(self, value, state):
if not register_model.user_name_is_unique(value):
raise validators.Invalid(self.message('notUnique', state),
value, state)
return value
and then do the rest in the model.
