Form deactivation inside validate function

Hi @mac_71128,

I am currently using this to deactivate a form:

def validate(self, dispatcher, tracker, domain):
    # type: (CollectingDispatcher, Tracker, Dict[Text, Any]) -> List[Dict]
    """Extract and validate value of requested slot.

    If nothing was extracted reject execution of the form action.
    Subclass this method to add custom validation and rejection logic
    """

    slot_to_fill = tracker.get_slot(REQUESTED_SLOT)

    reset = self._check_reset_form_action_on_intent(tracker=tracker, dispatcher=dispatcher)
    if reset:
        return self.deactivate()

Where self._check_reset_form_action_on_intent(tracker=tracker, dispatcher=dispatcher) is implemented like this:

def _check_reset_form_action_on_intent(self, tracker: Tracker, dispatcher):
    """

    :param tracker:
    :param dispatcher:
    :return:
    """
    last_intent = tracker.latest_message['intent'].get('name')
    if last_intent == 'reset_dialogue':
        dispatcher.utter_message('Okay, gern. Was kann ich sonst für Sie tun?')
        return True
    else:
        return False

Of course there won’t be any need of using such a method - you can return the deactivate statement right out of validate, if that suits your case.

Did that help you?

Regards
