getting error running django

Using Django Mystery Errors
1

I’m not able to run python manage.py runserver. I was able to run python manage.py migrate successfully. I even changed ASGI_APPLICATION = "MyProject.asgi.application" to ASGI_APPLICATION = "routing.application" which didn’t work. Here is the error I get

I think this has to do with the Django-Channels library I installed/imported.

I think it has something to do with my StopConsumers import statement in consumers.py

import json
from channels.exceptions import StopConsumer
from channels.generic.websocket import AsyncJsonWebsocketConsumer
import base64


# Channel consumer for both chat room group

class ChatConsumer(AsyncJsonWebsocketConsumer):
    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_layer)
        
    # 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 re(self, event):
        message = event['message']
        
        # send message to websocket
        await self.send(text_data=json.dumps({'message': message}))
        
        
# Channel Consumer that consumed events for uploading/receiving image files in the message room

class UploadImageConsumer(AsyncJsonWebsocketConsumer):
    async def connect(self):
        await self.accept()
        

    async def disconnect(self, close_code):
        raise StopConsumer()
    
    
    async def receive(self, bytes_data=None, text_data=None):
        if bytes_data:          
            # Handles image file chunks (binary data)
            
            with open('image.jpg', 'rb') as f:
                fcontent = f.read()
            await self.send(base64.b64encode(fcontent).decode('utf-8'))
        elif text_data:
            # Handles metadata (text data)
            
            await self.send(text_data=json.dumps({'message': text_data}))
            
            
    async def send_image(self, event):
        image_data = event['image_text']
        await self.send(bytes_data=image_data)
5

Did you create a routing.py? What is the content of that?

6

What directory is your asgi.py and wsgi.py files in?

7

So both asgi.py and wsgi.py files are both inside my MyProject folder, that is the same folder as my settings.py

8

Yes here is my routing.py

from django.urls import re_path

from . import consumers

websocket_urlpatterns = [
    re_path(r'ws/arborchat/(?P<room_name>\w+)/$', consumers.ChatConsumer.as_asgi)
]

Probably doesn’t help that I have two apps in my project, arborfindr, a separate app. I have another app, arborchat, which is my chat server app

9

Here is my edited consumers.py, I removed StopConsumer import for Channels

import json
from channels.consumer import AsyncConsumer

from channels.generic.websocket import AsyncJsonWebsocketConsumer
import base64


# Channel consumer for both chat room group

class ChatConsumer(AsyncJsonWebsocketConsumer):
    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_layer)
        
    # 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 re(self, event):
        message = event['message']
        
        # send message to websocket
        await self.send(text_data=json.dumps({'message': message}))
        
        
# Channel Consumer that consumed events for uploading/receiving image files in the message room

class UploadImageConsumer(AsyncJsonWebsocketConsumer):
    async def connect(self):
        await self.accept()
        

    async def disconnect(self, close_code):

        async def receive(self, bytes_data=None, text_data=None):
            if bytes_data:
            # Handles image file chunks (binary data)
            
                with open('image.jpg', 'rb') as f:
                    fcontent = f.read()
                await self.send(base64.b64encode(fcontent).decode('utf-8'))
            elif text_data:
                # Handles metadata (text data)
            
                await self.send(text_data=json.dumps({'message': text_data}))
            
            
    async def send_image(self, event):
        image_data = event['image_text']
        await self.send(bytes_data=image_data)
        ```

Apparently this library is outdated. But still getting the same error

This

is the actual error message.

If you can post asgi.py file also! Also, when does the error appear? On server run? On you refresh the webpage? Automatically after serve run?

12

Here is asgi.py

"""
ASGI config for MyProject project.

It exposes the ASGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/4.2/howto/deployment/asgi/

import os

import arborchat.routing
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.security.websocket import AllowedHostsOriginValidator
from django.core.asgi import get_asgi_application
from arborchat.routing import websocket_urlpatterns
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'MyProject.settings')

django_asgi_app = get_asgi_application()

application = ProtocolTypeRouter(
{
    "http": django_asgi_app,
    "websocket": AllowedHostsOriginValidator(
        AuthMiddlewareStack(URLRouter(websocket_urlpatterns))
    ),
}
)

So there is apparently no module arborchat and no reference to websocket_urlpattern

13

The error occurs when I run python manage.py runserver. So server run

14

Change it to "http":get_asgi_application(),

15

I changed it. But there are still errors in asgi.py with module name arborchat and websocket_urlpattern

16

I think old

was fixed then.

Post the new error message.
