SlotSet vs retrun{slot_name: value}

Hello everyone,

I would like to ask, what is the difference between the return[SlotSet(slot_name, value)] and the return{"slot_name":value}?

I was taking them as similar but I am not sure if this is correct.

@EvanMath Nice question.

return[SlotSet(slot_name, value)]

This means: set slots to extracted values Ref:


This means: validation method, to validate the slots, where you want to return {<slot_name>, value} if validation succeeds else print an error message and return {<slot_name>, None}. Ref: Forms

I hope this will clear your doubt and solve your topic post. Good Luck!

Hey @nik202 , thnks again for your reply. So in this case

the slot is already been set and we just say it’s ok to use this value otherwise change it to β€œNone” and print an error message? This command it could follow the SlotSet.

@EvanMath this I guess you can used for validation; please check the suggested link, what you asked I suggested you the same.

For example:

 if slot_value.lower() in self.cuisine_db():
            # validation succeeded, set the value of the "cuisine" slot to value
            return {"cuisine": slot_value}
            # validation failed, set this slot to None so that the
            # user will be asked for the slot again
            return {"cuisine": None}

I have gone through all these links. I think we are saying the same thing here. Anyway, thank you.

@EvanMath Your are welcome :handshake:, please close this thread as a solution for others and Good Luck!
