Exception inside application: 'module' object is not callable

My django-channels app works fine using manage.py runserver but when I am trying to run through daphne it is showing me the following error on running daphne -b 0.0.0.0 -p 8000 djangoProject.asgi:stream

Here is my asgi.py

#djangoProject/asgi.py
import os

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
from django.core.asgi import get_asgi_application
import stream.routing

django_asgi_app = get_asgi_application()

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "djangoProject.settings")
application = ProtocolTypeRouter({
  "http": django_asgi_app,
  "websocket": AuthMiddlewareStack(
        URLRouter(
            stream.routing.websocket_urlpatterns
        )
    ),
})

Here is the stream.routing:

# chat/routing.py
from django.urls import re_path

from .consumers import StreamConsumer, PercentageConsumer

websocket_urlpatterns = [
    re_path(r'ws/live/', StreamConsumer.as_asgi()),
    re_path(r'ws/percentage/', PercentageConsumer.as_asgi()),
]

Settings.py relevent code

    'django.contrib.contenttypes',
    'django.contrib.sessions',

        'BACKEND': 'channels_redis.core.RedisChannelLayer',
        'CONFIG': {

    },
}

So the application is asgi:application no?

[sohambhardwaj]

I am so sorry dude. Closing this.

[KensingtonOscupant]

Sorry to bring this up again, I haven't connected the dots yet. Where is the asgi:application supposed to go?

[carltongibson]

Does this not work: daphne -b 0.0.0.0 -p 8000 djangoProject.asgi:application ?

i.e. It's the application variable inside the djangoProject/asgi.py file that is the ASGI application that Daphne needs to run.

got it, thanks!
