Issue with handling conditional slot logic and validations in the same action in Rasa 2.0

@SamS Thanks for the reply! I posted an question here and here and it was (eventually) responded to but didn’t really help me with an example. i’ve pasted it here if it helps. The main thing I need help with is how to code the action.py so that it asks sequential questions and then takes in any text input:

I’ve been having difficulty coming up with a custom action to fill slots with open ended texts (after reading all the documentation and looking at the working examples on github). Below is my code. I’d really like some help. Here, I want the bot to ask two questions in order (and I would like it to do it in custom actions).

  1. Would you like to talk about your sleep?
  2. How would you describe your sleep?

I want the second question to capture any text, no matter how long, and return it in a variable that I can dump in a spreadsheet later. I’m really confused how I ask both questions in the action.py file.

The form is triggered by this intent in the NLU

- intent: sleep_log
  examples: |
    - I'd like to log my sleep

The domain of the form is:

responses:
  utter_confirm_sleep:
  - text: Do you want to talk about how you slept?

forms:
  sleep_form:
    sleep_confirm:
      - type: from_intent
        intent: affirm
        value: True
      - type: from_intent
        intent: deny
        value: False
      - type: from_intent
        intent: inform
        value: True

And, STORIES:

- story: sleep happy path
  steps:
  - intent: sleep_log
  - action: utter_confirm_sleep
  - intent: affirm
  - action: sleep_form
  - active_loop: sleep_form

ACTIONS

class ValidateSleep(FormValidationAction):
    print ("sleep form triggered")
    def name(self) -> Text:
        print ('validation run sleep')
        return "validate_sleep_form"

    
    async def validate_sleep_confirm(
        self,
        value: Text,
        dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any],
    ) -> Dict[Text, Any]:
        if value:
            print ('true value of sleep confirmed')
            return {"sleep_confirm": True}
        else:
            print ('false value sleep confirmed')
            return {"sleep_confirm": False }
    
    async def required_slots(
        self,
        slots_mapped_in_domain: List[Text],
        dispatcher: "CollectingDispatcher",
        tracker: "Tracker",
        domain: "DomainDict",
    ) -> Optional[List[Text]]:
        required_slots = slots_mapped_in_domain + ["sleep_description"]
        print ('required slot triggered')
        return required_slots

    async def extract_sleep_description(
        self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict
    ) -> Dict[Text, Any]:
        text_of_last_user_message = tracker.latest_message.get("text")
        sleep_description = "slept" in text_of_last_user_message
        dispatcher.utter_message(text="please describe your sleep")

        return {"sleep_description": sleep_description}

Please let me know how I can make this question any more clear. I’m new but eager to learn how to do this. Thank you!!
