Hello.

I’m clear that in order to retrieve first and last names from de objetct telegram.user of telegram.message i need to customize channel.py , return in get_metadata() values extracted from the message of Telegram writting in the tracker record metadata field.

But…, anyone have an example of doing that?

Thanks.

I did this in my channel.py in rasa\core\channels\channel.py

def get_metadata(self, request: Request) -> Optional[Dict[Text, Any]]:
        metadata=request.json#transfers the request to a python dictonary and make it readable in python
        
        print("Metadata: ",str(metadata))
        print("Type Metadaten: ",type(metadata))
        print("User ID:", metadata["message"]["from"]["id"])
        return metadata

In my actions.py I did this

class ActionGetSenderId(Action):

def name(self):
    return "action_get_sender_id"

def run(self, dispatcher, tracker, domain):
    input_data=tracker.latest_message
    print(input_data["metadata"]["message"]["from"])
    
    user_info=input_data["metadata"]["message"]["from"]
    user_name=input_data["metadata"]["message"]["from"]["first_name"]
    
    str_greet_name="Your name is "+user_name
    dispatcher.utter_message(text=str_greet_name)

And like always you need to add you action to your domain and story…

Since I overwrote get_metadata it transvers the metadata to the telegram.py in my channels.

Hi! I Can’t find rasa\core\channels\channel.py It’s not in python directory

It’s not in Python’s directory… Found it in the virtual enviroment I created. ( using anaconda package enviroment)
