I want to fetch the entities that are parsed and set the values of the entity in the slot. In the documentation, it is mentioned that I can use ‘get_latest_entity_values’ under Dialogue state tracker for fetching the entities that are parsed. Please help me with the parameter that I have to pass to make the get_latest_entity_values call and how to make the call

@JiteshGaikwad I am updating the slot using slotset function but the slot is not updating def run(self, dispatcher, tracker, domain): key = tracker.latest_message.intent["name"] l_confidence = tracker.latest_message.intent["confidence"] logger.info(key) logger.info(l_confidence) logger.info(tracker.get_slot("number")) logger.info(tracker.get_slot("so")) [SlotSet("so", key)] logger.info(tracker.get_slot("so")) return Output: 2019-01-30 13:57:24 INFO bot - material_list 2019-01-30 13:57:24 INFO bot - 0.9565813541412354 2019-01-30 13:57:24 INFO bot - 765678 2019-01-30 13:57:24 INFO bot - None 2019-01-30 13:57:24 INFO bot - None

Hey, You have to return the slot set function for it to work: return [SlotSet("so", key)]

@srikar_1996 thank you :slight_smile:

@srikar_1996 slot value is reflecting in the console but not reflecting in parse continue call story: story_material_list material_list{“number” : “number”} action_test action_test2 console op: Bot loaded.

Can you post a snap of the function? Not sure what is wrong.

class ActionTest(Action): def name(self): return 'action_test' def run(self, dispatcher, tracker, domain): key = tracker.latest_message.intent["name"] l_confidence = tracker.latest_message.intent["confidence"] logger.info(key) logger.info(l_confidence) logger.info(tracker.get_slot("number")) logger.info(tracker.get_slot("so")) logger.info(type(key)) return [SlotSet("so", key)] class ActionTest2(Action): def name(self): return 'action_test2' def run(self, dispatcher, tracker, domain): key = tracker.latest_message.intent["name"] l_confidence = tracker.latest_message.intent["confidence"] logger.info(key) logger.info(l_confidence) logger.info(tracker.get_slot("number")) logger.info(tracker.get_slot("so")) return []

What about action_test2? It should reflect in the second action. The parse output you posted is for the action_test right, and it is returning the slot value so it should be available from for the subsequent actions. Actually, can you try accessing it in the next story and see if the value is still there?

1. http://172.16.0.195:5030/conversations/8/parse {"query":"Materials against so 9514443459"} op: { "next_action": "action_test", "tracker": { "events": null, "latest_event_time": 1548840717.5628903, "latest_message": { "entities": [ . . . . ], "text": "Materials against so 9514443459" }, "paused": false, "sender_id": "8", "slots": { "number": 9514443459, "so": null } } 2. http://172.16.0.195:5030/conversations/8/continue {"executed_action":"action_test"} { "next_action": "action_test2", "tracker": { "events": null, "latest_event_time": 1548840795.7925394, "latest_message": { "entities": [ . . . ], "text": "Materials against so 9514443459" }, "paused": false, "sender_id": "8", "slots": { "number": 9514443459, "so": null } } } 3. http://172.16.0.195:5030/conversations/8/continue {"executed_action":"action_test2"} op: { "next_action": "action_listen", "tracker": { "events": null, "latest_event_time": 1548840915.2218843, "latest_message": { "entities": [ { "additional_info": { "type": "value", "value": 9514443459 }, "confidence": 1, "end": 31, "entity": "number", "extractor": "ner_duckling_http", "start": 21, "text": "9514443459", "value": 9514443459 } ], . . . "text": "Materials against so 9514443459" }, "paused": false, "sender_id": "8", "slots": { "number": 9514443459, "so": null } } }

Oh, that’s strange. I’m not sure why the value isn’t being passed in the response. Anyway, can you try accessing the value in the next story and see?
