Can Rasa put values in 'to' and 'from' of a duckling output type interva to slots automatically?

How to handle this kind of situation? [{'start': 0, 'end': 17, 'text': 'today 3 am to 4am', 'value': {'to': '2021-09-17T05:00:00.000-07:00', 'from': '2021-09-17T03:00:00.000-07:00'}, 'confidence': 1.0, 'additional_info': {'values': [{'to': {'value': '2021-09-17T05:00:00.000-07:00', 'grain': 'hour'}, 'from': {'value': '2021-09-17T03:00:00.000-07:00', 'grain': 'hour'}, 'type': 'interval'}], 'to': {'value': '2021-09-17T05:00:00.000-07:00', 'grain': 'hour'}, 'from': {'value': '2021-09-17T03:00:00.000-07:00', 'grain': 'hour'}, 'type': 'interval'}, 'entity': 'time', 'extractor': 'DucklingEntityExtractor'}]

Is it possible to handle using role in DIETclassifier? or someother way that I can put the values in “to” and “from” into respective slots?

@athulvingt Heya! Please see this concept on the doc : Forms whilst using roles.

3

that “role” can only be used with DIETClassifier, Righr? Is it possible to use with Duckling?

@athulvingt Bro, honestly that’s a trick question you asked :thinking: I not tried, but give it a try please. Make sure you prove good examples for the same.

I wrote a separate code to handle this, purely duckling

@athulvingt Nice, If you got time please do share your code and solution with us and close this thread :slight_smile:

the solution is depended on use case. This is how i coded

def convert_time(time_str):
    date_time = time_str[:19]
    time_str = datetime.datetime.strptime(date_time, "%Y-%m-%dT%H:%M:%S")
    return time_str

def process_time(entity,tracker):
    checkin = tracker.get_slot("checkin")
    checkout = tracker.get_slot('checkout')
    entry_t= tracker.get_slot('entry_t')
    exit_t= tracker.get_slot('exit_t')
    if entity['entity'] == 'time':
        if isinstance(entity['value'],str):
            time_ = entity['value']
            if not checkin:
                checkin = time_
            elif checkin and not entry_t:
                checkin = checkin[:11] + time_[11:19]
                entry_t = time_[11:19]
            else:
                checkout = checkin[:11] + time_[11:19]
                exit_t = time_[11:19]
        if isinstance(entity['value'], dict):
            to_ = entity['value']['to']
            from_ = entity['value']['from']
            if not checkin :
                checkin, checkout, entry_t, exit_t = to_ , from_, to_[11:19],from_[11:19]
            else:
                checkin, entry_t = checkin[:11] + to_[11:19], to_[11:19]
                checkout, exit_t = checkin[:11] + from_[11:19], from_[11:19]
    return {"checkin": checkin, "entry_t": entry_t, "checkout":checkout, "exit_t":exit_t}

class ValidateAttractionBookingForm(FormValidationAction):
    def name(self) -> Text:
        return "validate_attraction_booking_form"
      ( ........)

  async def validate(self, dispatcher, tracker, domain):
        slots: Dict[Text, Any] = tracker.slots_to_validate()
        entity_list = tracker.latest_message['entities']
        for entity in entity_list:
            if entity['extractor'] == 'DucklingEntityExtractor':
                time_slot = process_time(entity,tracker)
                for i in time_slot :
                    slots[i] = time_slot[i]
      ( ........)
    return [SlotSet(slot, value) for slot, value in slots.items()]

@athulvingt mark above post as solution for other and thanks a lot for sharing your code with us :slight_smile:
