Hi ! During some tests with Role Entities, I figure out my slot mapping doesn’t work like I tought. Currently, it work because my slots names and my entities names are the same. But I tried to change one and it is not fill now. My test is with the same intent, it trigger the FormAction action_get_top_users which the beginning is : class ActionGetTopUsers(FormAction): def name(self) -> Text: return "action_get_top_users" @staticmethod def required_slots(tracker: Tracker) -> List[Text]: """A list of required slots that the form has to fill""" return ["moment", "application"] def slot_mappings(self) -> Dict[Text, Any]: return {"moment": self.from_entity(entity="moment", intent=["moment_added", "top_users"]), "application": self.from_entity(entity="application", intent=["application_added", "top_users"]), "site": self.from_entity(entity="city-site", intent=["city_added", "top_users"])} If i had site to my requested slot (just by adding it in the list of required_slot), the debug is 2020-05-25 15:07:45 **DEBUG** rasa_sdk.forms - Activated the form 'action_get_top_users' 2020-05-25 15:07:45 **DEBUG** rasa_sdk.forms - Validating pre-filled required slots: {'moment': 'hier', 'application': 'skype'} 2020-05-25 15:07:45 **DEBUG** rasa_sdk.forms - Validating user input '{'intent': {'name': 'top_users', 'confidence': 0.9999955296516411}, 'entities': [{'entity': 'application', 'start': 14, 'end': 19, 'value': 'skype', 'extractor': 'DIETClassifier'}, {'entity': 'moment', 'start': 20, 'end': 24, 'value': 'hier', 'extractor': 'DIETClassifier'}, {'entity': 'city-site', 'start': 27, 'end': 32, 'value': 'Porto', 'extractor': 'DIETClassifier'}], 'intent_ranking': [{'name': 'top_users', 'confidence': 0.9999955296516411}, {'name': 'mood_unhappy_return_question', 'confidence': 2.146076894860016e-06}, {'name': 'goodbye', 'confidence': 5.99835573211749e-07}, {'name': 'temperature', 'confidence': 5.354330596674117e-07}, {'name': 'mood_great_return_question', 'confidence': 3.627311855325388e-07}, {'name': 'bot_challenge', 'confidence': 2.8670544338638143e-07}, {'name': 'greet', 'confidence': 1.801675466595043e-07}, {'name': 'deny', 'confidence': 1.6207697228765017e-07}, {'name': 'reseau_action', 'confidence': 1.442294745856998e-07}, {'name': 'weather', 'confidence': 8.303375409468572e-08}], 'text': 'qui a utilisé skype hier à Porto ?'}' 2020-05-25 15:07:45 **DEBUG** rasa_sdk.forms - Extracted 'hier' for extra slot 'moment'. 2020-05-25 15:07:45 **DEBUG** rasa_sdk.forms - Extracted 'skype' for extra slot 'application'. 2020-05-25 15:07:45 **DEBUG** rasa_sdk.forms - Extracted 'Porto' for extra slot 'site'. 2020-05-25 15:07:45 **…

The custom slot mappings only work for requested slots, see the example in de docs . If you want to see how this is implemented you can also check the get_mappings_for_slot function.

Okay thank you, but in fact I don’t see in the documentation that Slot Mapping only works for requested Slot, I think it should be interesting to precise it. So now, I only need to find how to set not requested slot !

I agree that it is somewhat unclear but the first sentence of the comment in the code example states: “A dictionary to map required slots to…”

ow I’m sorry, this is true ^^" Read better would avoid me some trouble

To set a slot that has not been requested you could try to hook into the request_next_slot: def request_next_slot(self, dispatcher, tracker, domain): next_slot = super().request_next_slot(dispatcher, tracker, domain) # All required slots have been filled if not next_slot: # Check whether the 'site' slot has been filled if not tracker.get_slot('site'): # Set the slot return [SlotSet('site', 'foobar')] return next_slot My use of the function is a little different so I’m not 100% sure if the code above will work directly for your usecase.

@flythe globally, your code is good, i can have optional slot, but when I have one, I need to do an other input to launch my action. Thank you, I keep looking for a solution.

If a slot is not requested, slot mapping doesn't work
