class ChatConsumer(WebsocketConsumer):
    def connect(self):
        self.user = self.scope["user"]
        self.group_name = f"user_{self.user.id}_group"
        print("my group: ", self.group_name)
        self.accept()
        async_to_sync(self.channel_layer.group_add(self.group_name, self.channel_name))

    def disconnect(self, close_code):
         async_to_sync(self.channel_layer.group_discard(self.group_name, self.channel_name))

    def receive(self, text_data):
        self.chat_id = self.scope["url_route"]["kwargs"]["chat_id"]
        data = json.loads(text_data)

        message_content = data["message"]
        recipient_user_id = data["recipient_user_id"]

        recipient = User.objects.get(id=recipient_user_id)
        message = Message.objects.create(
            chat_id=self.chat_id, owner=self.user, content=message_content
        )
        message.recipients.add(recipient)
 
        recipient_group_name = f"user_{recipient_user_id}_group"
        async_to_sync(
            self.channel_layer.group_send(
                recipient_group_name,
                {
                    "type": "chat_message",
                    "message": message_content,
                    "owner": self.user.id,
                },
            )
        )

    def chat_message(self, event):
        message = event["message"]
        owner = event["owner"]

        self.send(
            text_data=json.dumps(
                {
                    "message": message,
                    "owner": owner,
                }
            )
        )
