How to avoid form validation after SlotSet event

Rasa Open Source
1

Hello,

I would like to know if it is possible to avoid the form validation when a slot is being defined in a custom action through SlotSet(‘slot_name’, value). I don’t know if this is very clear, so here’s a concrete example:

#rules.yml
version: "2.0"

rules:

- rule: just a test
  steps:
  - intent: test
  - action: action_check
  - action: info_form
  - active_loop: null

#domain.yml
session_config:
  session_expiration_time: 60
  carry_over_slots_to_new_session: true
intents:
- hi
- test
- give_slot_2:
    use_entities:
    - slot_2
entities:
- slot_1
- slot_2
slots:
  slot_1:
    type: any
    influence_conversation: false
  slot_2:
    type: any
    influence_conversation: false
responses:
  utter_ask_slot_2:
  - text: What's the slot_2 ?
  utter_bye:
  - text: bye
actions:
- validate_info_form
- action_check
forms:
  info_form:
    slot_2:
    - entity: slot_2
      intent: give_slot_2
      type: from_entity
    slot_1:
    - entity: slot_1
      type: from_entity

#actions.py
from typing import Any, Text, Dict, List, Union

from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher
from rasa_sdk.forms import FormAction
from rasa_sdk.events import SlotSet


class ValidateInfoForm(Action):
    def name(self) -> Text:
        return "validate_info_form"

    def run(self, dispatcher, tracker, domain):
        required_slots = ["slot_1", "slot_2"]

        for slot_name in required_slots:
            if tracker.slots.get(slot_name) is None:
                print("This line is printed twice :(")
                return []

        # All slots are filled.
        return [SlotSet("requested_slot", None)]


class Check(Action):
    def name(self) -> Text:
        return "action_check"

    def run(self, dispatcher, tracker, domain):
       return [SlotSet("slot_1", "abcde")]

This code leads to the following conversation:

This line is printed twice :(
This line is printed twice :(

The first call to the run() method of the ValidateInfoForm class is made because SlotSet(“slot_1”, “abcde”) is returned in the Check class. Then, it is called again because of the line “- action: info_form” in my rule. Well, at least that’s what I understood, I could be wrong,

So, is there a way to set the slot “slot_1” in my Check class without triggering the validation ?

Thank’s in advance

Can I ask why you would want to skip validation?
