ASGI_APPLICATION not working with Django Channels

Question

I followed the tutorial in the channels documentation but when I start the server python3 manage.py runserver it gives me this :

Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).
October 17, 2022 - 00:13:21
Django version 4.1.2, using settings 'config.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

when I expected for it to give me this :

Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).
October 17, 2022 - 00:13:21
Django version 4.1.2, using settings 'config.settings'
Starting ASGI/Channels version 3.0.5 development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

settings.py

INSTALLED_APPS = [
    'channels',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    ...
]

ASGI_APPLICATION = 'config.asgi.application'

asgi.py

import os
from django.core.asgi import get_asgi_application
from channels.routing import ProtocolTypeRouter

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'config.settings')

application = ProtocolTypeRouter({
    'http': get_asgi_application(),
})

It doesn’t give any errors even when I change the ASGI_APPLICATION = 'config.asgi.application to ASGI_APPLICATION = ''.

Answer 1

This could be due to the fact that the Django and channels versions you have used are not compatible
Try : channels==3.0.4 and django==4.0.0

Answer 2

Use version of python that support by channels, you will found it at pypi channels page

Answer 3

I had the same problem, and found that there was a new release of Channels. Since the project’s Pipfile did not specify a version, it was automatically upgraded.

Maybe you had the same issue, your question was asked 2 days after Channels v4.0 release.

Downgrading to v3.0.5 again solved the problem until I can properly upgrade.

Answer 4

Had the same with django=4.1.4, channels=4.0.0

My solution:

install channels with daphne (i did not remove or did anything to previously installed channels; operating in the same venv)

python -m pip install -U channels["daphne"]

put daphne in INSTALLED APPS, do not put channels there:

INSTALLED_APPS = ( "daphne", "django.contrib.auth",...

in settings.py add ASGI_APPLICATION:

ASGI_APPLICATION = "myproject.asgi.application"

Answer 5

At the first:

pip install daphne
pip install channels

And then update setting.py:

INSTALLED_APPS = [
    'daphne',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

Just this.
