How to change the slot question if validation fails?

ayadi · April 29, 2022, 11:06am

Hello there! I am using Rasa 3.0 and I was wondering is there any possible method to change the question of a slot during a form so for example, the bot will ask the user for his email " Can you give me your email address" and if the user types something else so that the slot is not filled the bot will keep asking for his email in the same way I want to change the question on the second try for example “Sorry, that’s not a valid email address. Can you please try again!”

Hi!

You can use FormValidationAction

Please, look this github example

github.com

RasaHQ/rasa-2.x-form-examples/blob/main/05-validation/actions/actions.py#L8

    
      
          from typing import Text, List, Any, Dict
          
          
from rasa_sdk import Tracker, FormValidationAction
          from rasa_sdk.executor import CollectingDispatcher
          from rasa_sdk.types import DomainDict
          
          

          
class ValidateNameForm(FormValidationAction):
              def name(self) -> Text:
                  return "validate_name_form"
          
          
    def validate_first_name(
                  self,
                  slot_value: Any,
                  dispatcher: CollectingDispatcher,
                  tracker: Tracker,
                  domain: DomainDict,
              ) -> Dict[Text, Any]:

Hello, thanks for your reply I used the form validation but the bot will send the message like this “Sorry, that’s not a valid email address. Can you please try again! Can you give me your email address” I just want to send the first message only
