I’m trying to get django channels running with daphne but I always end up with this
x8/backback/mysite » daphne mysite.asgi:application 1 ↵

I have
Django==3.1.7
daphne==3.0.1
channels==3.0.3
I successfully finished the channels setup from their site https://channels.readthedocs.io/en/stable/tutorial/part_1.html
But in the end it doesn’t work with daphne when I try a simple:
daphne mysite.asgi:application
or
daphne -p 8001 mysite.asgi:application
This is my current asgi.py
import os
import django
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
from django.core.asgi import get_asgi_application
import chat.routing
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
django.setup()
application = ProtocolTypeRouter({
"http": get_asgi_application(),
"websocket": AuthMiddlewareStack(
URLRouter(
chat.routing.websocket_urlpatterns
)
),
})
Before runserver I also tried :
export DJANGO_SETTINGS_MODULE=mysite.settings
While doing the channels tutorial, they ask us to make sure that the channel layer can communicate with Redis (part 2 of the turorial)
$ python3 manage.py shell
>>> import channels.layers
>>> channel_layer = channels.layers.get_channel_layer()
>>> from asgiref.sync import async_to_sync
>>> async_to_sync(channel_layer.send)('test_channel', {'type': 'hello'})
>>> async_to_sync(channel_layer.receive)('test_channel')
{'type': 'hello'}
If I use the python3 shell directly instead of python3 manage.py shell I get a similar error to the one I get now while trying to run daphne. I guess there is a connection, maybe, but I can't figure out where and why. I've spent days on this, doing and redoing, please help ~
