Hi Dear
( I use Google Translator ) 
I'm Korea devoleper,
please help,

I am developing two projects.
I saw the tutorial and created chat features for both projects.
The code for both projects is the same.  
But one of them is a problem.


[A user] creates a chat room and enters [B user].
Chatting is good so far.
However, if [B user] creates a room for another room_name
You can not chat in both rooms.

It does not pass from receive in consumers.py to chat_message.
( Chatting alone will be done immediately after [B user] creates a room. 
  The chat_room of [A user], [B user] Only two or three chats are available.)


Emphasize again, one of the projects works normally. 

 
I have not been able to fix it for a few days.......
Please help me.....ㅜ_ㅜ

Thank you.
Good day.

Could you share your repository? We need more details to determine what’s wrong. 

On a side note, I made a functional chat app with Django channels here: https://www.github.com/dibs-devs/chatter

Good luck!

What version of channels are you using?
How do you determine the channel _name for each chat rooms?

Could you share some code?

Viewed and produced basic tutorials

I'd like to show you if there's anything special about the code
It is 100% identical to the tutorial code



<!-- chat/templates/chat/index.html -->
<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8"/>
    <title>Chat Rooms</title>
</head>
<body>
    What chat room would you like to enter?<br/>
    <input id="room-name-input" type="text" size="100"/><br/>
    <input id="room-name-submit" type="button" value="Enter"/>

    <script>
        document.querySelector('#room-name-input').focus();
        document.querySelector('#room-name-input').onkeyup = function(e) {
            if (e.keyCode === 13) {  // enter, return
                document.querySelector('#room-name-submit').click();
            }
        };

        document.querySelector('#room-name-submit').onclick = function(e) {
            var roomName = document.querySelector('#room-name-input').value;
            window.location.pathname = '/chat/' + roomName + '/';
        };
    </script>
</body>
</html>



html that specifies room_name.
The same thing happens to any room_name

Is any error produced on your development server? Please post the code in your consumers.py file.

The development server does not display an error.
This is the same as normal operation.
However, the information is not sent to chat_message.


# chat/consumers.py
from channels.generic.websocket import AsyncWebsocketConsumer
import json

class ChatConsumer(AsyncWebsocketConsumer):
    async def connect(self):
        self.room_name = self.scope['url_route']['kwargs']['room_name']
        self.room_group_name = 'chat_%s' % self.room_name

        # Join room group
        await self.channel_layer.group_add(
            self.room_group_name,
            self.channel_name
        )

        await self.accept()

    async def disconnect(self, close_code):
        # Leave room group
        await self.channel_layer.group_discard(
            self.room_group_name,
            self.channel_name
        )

    # Receive message from WebSocket
    async def receive(self, text_data):
        text_data_json = json.loads(text_data)
        message = text_data_json['message']

        # Send message to room group
        await self.channel_layer.group_send(
            self.room_group_name,
            {
                'type': 'chat_message',
                'message': message
            }
        )

    # Receive message from room group
    async def chat_message(self, event):
        message = event['message']

        # Send message to WebSocket
        await self.send(text_data=json.dumps({
            'message': message
        }))



Thank you for your help.
