Hi, I want to insert slot value without using `return[SlotSet(' ',..)]`. How can I do that between the code? Is there something like **`tracker.set_slot()`** ---

you should do it with returning events as you mentioned ---

yeah I know it is in good practice but for setting that slot value I have to create a new custom action which don’t have any other work except setting slot value. That’s why I am searching for new method to setting slot. ---

Resolved!!! `tracker.slots[update_slot] = None` Checked with print slot is set but having an issue that it does not save slot in stories, stories have old slot values. Will try to resolve later. ---

@Ghostvv Yeah that’s the another and popular method but there are some people who need to fix the slots using `tracker.slots[]` method because they want to update slot in the middle of **custom\_action**. I am trying to help those people. P.S. Resolved my issue by using **SlotSet** method. Saw other posts so trying to help them. ---

Thank you for your response, when I am trying to update slots in middle of functions I got the above issue, now issue is resolved when I replace the return step as follows - return[SlotSet(’ ',…)]. Thank You. ---

so, when you update `tracker.slots`, you change the local copy of tracker, that is passed to the custom action, in order to notify `rasa_core` that the slot has changed, you need to return `SlotSet` event ---

@abhishakskilrock need to store some information as slots which are not actually part of required\_slots for my form. That’s why i was trying to update those slots using tracker.slots[‘slot\_name’]=slot\_value . I was doing it inside a slot validation method that needs to return the value of that particular slot. So, i can’t return anything but that slot inside that validation method. As you said i can see those slots being set just after using tracker.slots(). But if i call tracker.get\_slot() for those slots from a different method than it shows that the slots were not set. How did you resolve this? P.S : i can’t return SlotSet() event as the validation method should only return the particular slot the validation method was created for. Here is my code: ```auto def validate_bank_account_number( self, value: Text, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any], ) -> Dict[Text, Any]: """Validate cuisine value.""" intent_found=tracker.get_intent_of_latest_message() #print(intent_found) if intent_found=="last_two_transaction": #raise ActionExecutionRejection(self.name(),f"Failed to extract slot with action {self.name()}",deactivate_form=True) #raise ActionExecutionRejection(self.name(),f"Failed to extract slot with action {self.name()}") #return self._deactivate() #dispatcher.utter_message(template="utter_wrong_bank_account_number") FollowupAction(name="validate_last_two_transaction_form") list_valid=["জিরো","ওয়ান","টু","থ্রি","ফোর","ফাইভ","সিক্স","সেভেন","এইট","নাইন"] dict_word_to_digit={"জিরো":'0',"ওয়ান":'1',"টু":'2',"থ্রি":'3',"ফোর":'4',"ফাইভ":'5',"সিক্স":'6',"সেভেন":'7',"এইট":'8',"নাইন":'9'} print("i am from bank account section and my value is ",value) if type(value)==str: if len(value.split())==13: return {"bank_account_number": value} if type(value)!=list: dispatcher.utter_message(template="utter_wrong_bank_account_number") return {"bank_account_number": None} if len(value)!=3: dispatcher.utter_message(template="utter_wrong_bank_account_number") return {"bank_account_number": None} else: if len(value[0].split())!=13 and len(value[1].split())!=13 and len(value[2].split())!=13: dispatcher.utter_message(template="utter_wrong_bank_account_number") return {"bank_account_number": None} else: get_value=value[2] bank_id='' for i in get_value.split(): bank_id=bank_id+dict_word_to_digit[i] show_df=pd.read_csv('/home/zaowad/Desktop/rasa/bank_bot_v6/actions/demo_dataset.csv') try: val_collection=list(show_df[show_df['Bank ID']==int(bank_id)].values[0]) except: dispatcher.utter_message(template="utter_wrong_bank_account_number") return {"bank_account_number": None} print(bank_id) print(val_collection) tracker.slots["temp_name"]=val_collection[3] tracker.slots["temp_date_of_birth"]=val_collection[2] tracker.slots["temp_ballance"]=val_collection[4] tracker.slots["temp_transaction"]= val_collection[5] print(tracker.get_slot("temp_name")) print(tracker.get_slot("temp_date_of_birth")) print(tracker.get_slot("temp_ballance")) print(tracker.get_slot("temp_transaction")) return {"bank_account_number": bank_id} ``` ---

I know it’s a bit late, However, you can try something ```auto return [SlotSet("temp_name", val_collection[3]), SlotSet(["temp_date_of_birth", val_collection[2]), SlotSet("temp_ballance", val_collection[4]), SlotSet("temp_transaction", val_collection[5]), SlotSet("bank_account_number", bank_id), ] ``` should work. try ---

Hello, I have the same problem, that is, I want to save the slot value without returning it. How do you finally solve this problem? Looking forward to your reply, thank you very much!
