Rasa Open Source
1

I have 2 slots, patient_name and confirm_patient_name, i have validation of slot confirm_patient_name if user input everthing except “ya”, will reset value of patient_name (not confirm_patient_name). how do i do this?

    def validate_confirm_patient_name(
        self,
        slot_value: Any,
        dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: DomainDict,
    ) -> Dict[Text, Any]:
        if slot_value == "ya":
            '''dispatcher.utter_message(text=f"user confirm YA")'''
            return {"confirm_patient_name":True}
        else:
            '''dispatcher.utter_message(text=f"user confirm TIDAK")'''

            return {"confirm_patient_name":None}

i changing return like this but its not work as expected, im totally lost here

return {"patient_name":None}

Hi @wiraadmaja could you please share your domain.yml file, to double-check your slots section as well as the slot mappings? Please confirm rasa version too.

Yes you can!

 return {"confirm_patient_name": None, "patient_name": None}

Look at this example:

async def validate_password(value, dispatcher, tracker, domain):
    if not tracker.get_slot('loggedin'):
        username = tracker.get_slot('username')
        password = value

        db = DatabaseConnection()
        count = db.query(f'SELECT COUNT(*) FROM user_info WHERE Username = {username} AND Password = {password}')

        if count == 1:
             dispatcher.utter_message(f'You are now logged in as {username}.')
            return {'password': 'secret', 'loggedin': True}
        else:
            dispatcher.utter_message(f'Sorry, you entered an incorrect password for {username}.')
            return {'password': None, 'loggedin': False}

    else: # Already logged in
        username = tracker.get_slot('username').title()
        dispatcher.utter_message(f'You are already logged in as {username}.')
        return {'username': username, 'password': 'secret', 'loggedin': True}

On top of that, I noticed this in your domain:

The form is not asking to fill confirm_patient_name, so validate_confirm_patient_name() shouldn’t even run.

I’m already tell the return with other slot is not works, also validate_confirm_patient_name is works, i just dont give you complete actions.py, here the full complete (and still cannot reset slot patient_name inside validate_confirm_patient_name

complete actions.py :

return {"confirm_patient_name": None, "patient_name": None}

nope its also not work, its still not reset patient_name slot, also fyi my validate_confirm_patient_name is works, im using custom extract in actions.py, i tried to give the full code and full debug before but auto filter spam hide it

@wiraadmaja Is it correct to assume that confirm_patient_name is a dynamic slot you’re adding to the form only if patient_name is filled? According to the docs on dynamic form behaviour, you should have:

a) the extract_confirm_patient_name method in your FormValidationAction

b) override required_slots to include confirm_patient_name if patient_name is filled

Otherwise, it could be easier to add confirm_patient_name slot to form required_slots in the domain, with a from_intent slot mapping and use validate_confirm_patient_name method in your FormValidationAction.
