Re: Getting channels 2 to work

That code would be for Channels 1. Channels 2 is an entirely different import set - make sure you are using tutorials or answers specifically for 2.

Hello Everyone,

I am still having an issue with Channels that was never really solved in an earlier Stackoverflow question...

Why does :

from channels.asgi import get_channel_layer

result in :

from channels.asgi import get_channel_layer  ImportError: No module named asgi

I am using Django (2.03), Channels (2.02) and Python(3.5.1) within a virtual environment.  I also installed asgi_redis.

Hi John,

The ProtocolTypeRouter currently does this for you automatically as long as you don't specify a `http` handler. Otherwise, the ASGI application that runs Django's view system is channels.http.AsgiHandler

Hi Andrew,

first of all thanks for your reply. With your answer and the information from your blog I was able to get my asgi application running. 

Now I want to route all http traffic to django's viewsystem back as i dont need channel's http handling. On your blog you posted this snippet

application = ProtocolTypeRouter({

    "http": URLRouter([

        url("^", DjangoViewSystem),

    ]),

But how should the DjangoViewSystem class look like? There is no such file included.

Hi John,

It's not in an end-user-useable state quite yet, so apologies for it being hard to install. Crucially, the docs on ASGI_APPLICATION aren't written yet as I'm still working on authentication stuff!

A brief guide is:

 - Make an asgi.py as specified in http://channels.readthedocs.io/en/2.0/deploying.html

 - Make a channels.routing.ProtocolTypeRouter in your project's routing.py and configure this as needed (you'll have to read the code for now)

 - Point ASGI_APPLICATION to that root router.

I'll have a lot more docs and stuff coming soon as I start prepping Channels 2 for a beta release, which will include routing and setup examples.

Hi everyone,

I am stuck getting the new channels 2 to a working state. I installed django==2.0rc1,  and channels==2.0.x, daphne==2.0.x, asgiref==2.0.x from the git repo

channels is enabled inside the settings.py. I also created the asgi.py file in the direcotry of the wsgi.py file acording to the docs. But still i get this error

    raise ImproperlyConfigured("Cannot find ASGI_APPLICATION setting.")

django.core.exceptions.ImproperlyConfigured: Cannot find ASGI_APPLICATION setting.

So it seems that ASGI_APPLICATION has to be specified. So after adding the following line:

ASGI_APPLICATION='mytestproject.asgi.application'

and starting ./manage.py runserver it now complains again. So which value is supposed to be there?

      raise ImproperlyConfigured("Cannot find %r in ASGI_APPLICATION module %s" % (name, path))

django.core.exceptions.ImproperlyConfigured: Cannot find 'application' in ASGI_APPLICATION module mytestproject.asgi

I need to stick to version 2 as i want to try out asgigram (https://github.com/andrewgodwin/asgigram).

Thanks
