Ask for missing entities

Hi Team,

Is there any way to query for missing entities in user queries other than creating separate stories for a case with entity and for a case without entity

What I am looking for is an option to define certain entities as mandatory entities. If that entity is not present in user query then RASA has to query user for that entity with a predefined question.

With the above things the NLU database will have following fields (4 and 5 are enhancement requests)

  1. Intent name
  2. Entity Name
  3. Entity value
  4. Mandatory/optional
  5. Predefined question to ask the user if a mandatory entity is missing

Thanks and Regards Ashwin

Use Form field for mandatory entities in custom action
