Django send full QuerySet in Channels

Question

I am using Django Channels to build a game. It's a super simple multiplayer chance game. After user clicks a button the game starts and the server receives the data via Channels. I do the necessary calculations, database updates etc. Now I want to send data back to the browser. I do a filter query from the database and I would like to send the whole query back. I know I could take out the necessary data one by one and send them separately but I feel like there's a better way but I just can't figure it out.

When I would send the QuerySet like in views.py I get a TypeError: Object of type QuerySet is not JSON serializable.

Sending the query using list() also gives me an error ValueError: The QuerySet value for an exact lookup must be limited to one result using slicing.

Is there a way I could send the whole QuerySet with Channels?

consumer.py

async def send_message(self, event):
        room_name = event['room_name']

        roomObj = cbr.objects.filter(room_name=room_name)
        cbObj = cb.objects.filter(room=roomObj)

        #cbObj is what I would like to send 

        await self.send(text_data=json.dumps({
            'cb': cbObj
            # Gives TypeError
        }))
