Rasa表单操作无法获取值

问题描述 投票:0回答:1

我一直在和rasa一起工作,还有一些我仍然不太了解的formAction,我今天的问题是为什么?我的formAction被激活,但它不存储任何slotvalue,如果我使用不正确?这是我的代码:

class HotelForm(FormAction):
  def name(self):
    # type: () -> Text
    return "formaejemplo"

  @staticmethod
  def required_slots(tracker):
    return ["tipo_habitacion"]

  def slot_mappings(self):
    return {'tipo_habitacion':[self.from_entity(entity='tipo_habitacion',intent=['gethabitacion','peticion_habitacion'])]}

  @staticmethod
  def habitaciones_db():
    return ["individual","doble","suite","suite doble"]

  def submit(self, dispatcher, tracker, domain):
    dispatcher.utter_template('utter_listo', tracker)
    return []


  def validate(self,dispatcher: CollectingDispatcher,tracker: Tracker,domain: Dict[Text, Any]) -> List[Dict]:
    slot_values = self.extract_other_slots(dispatcher, tracker, domain)
    print('slot values:',slot_values)
    slot_to_fill = tracker.get_slot(REQUESTED_SLOT)
    if slot_to_fill:
        print('slot values:',slot_values)
        slot_values.update(self.extract_requested_slot(dispatcher,tracker, domain))

    if not slot_values:
        try:
            return super().validate(dispatcher, tracker, domain)
        except ActionExecutionRejection as e:
            # could not extract entity
            dispatcher.utter_message(
                "Sorry, I could not parse the value correctly. \n"
                "Please double check your entry otherwise I will ask you this forever"
            )
            return []

    for slot, value in slot_values.items():
      print('Slot: ',slot)
      print('valor: ',values)
      if slot == 'tipo_habitacion':
        if value.lower() not in self.habitaciones_db():
          dispatcher.utter_template('utter_wrong_tipo_habitacion', tracker)
          # validation failed, set slot to None
          slot_values[slot] = None     

    # validation succeed, set the slots values to the extracted values
    return [SlotSet(slot, value) for slot, value in slot_values.items()]

当我在控制台上打印值(slotvalues)时,它总是为空。

当你第一次使用print('slot values:',slot_values)时,它只收集了额外的插槽(所需插槽的实体,它没有要求,但无论如何都要拾取)。您不应该拥有任何这些,因为您只有一个必需的插槽。

至于你第二次print('slot values:',slot_values),你在slot_values.update(self.extract_requested_slot(dispatcher,tracker, domain))之前做的,所以它和以前完全一样。更新发生后尝试打印它。如果您没有遇到if not slot_values逻辑,那么如果您在更新后移动它,它应该正确打印。

当你做这些线时它是否正确打印?

      print('Slot: ',slot)
      print('valor: ',values)
