Custom Slot extraction and validation fails using custom actions

Rasa Open Source
3

Hi, thank you so much for responding to my topic. Indeed I’ve noticed those two mistakes but somehow it didn’t fix my other issue, so I did more documentation reading and research and found out that the custom slot extract actions are always run on the background to keep the slots updated.

Here’s the action server log after fixing the two mistakes (I added a print in all methods for debugging):

I later found someone with the same issue, NoxDv on Github suggested to add a conditional statement in each extract method if tracker.slots[“requested_slot”] == “model” and it worked :+1:.

Here is the extract method for model after adding that conditional statement:

async def extract_model(
         self,
         dispatcher:CollectingDispatcher,
         tracker: Tracker,
         domain: DomainDict,
     ) -> Dict[Text, Any]:

     print("Extract model")
    print(tracker.slots["requested_slot"] == "model")
    if tracker.slots["requested_slot"] == "model":
        text_of_last_user_message = tracker.latest_message.get("text")
        model= text_of_last_user_message
    
        if model not in models:
            print(model)
            
            print(tracker.get_slot("model"))
            return {"model": None}
           
        print(tracker.get_slot("model"))
        return  {"model": model}
        
    print(tracker.get_slot("model")) 
    return {"model": tracker.get_slot("model")}

Thank you all for the help!
