Channels with django signals
Hi everyone, I am trying to send a channels message from a django signal. The problem ist that the signal function is not async. So I tried to use the AsyncToSync wrapper. But it seems this is not possible as the signal handler is run by a thread and has no event loop. ... self.main_event_loop = asyncio.get_event_loop() File "/usr/lib/python3.5/asyncio/events.py", line 632, in get_event_loop return get_event_loop_policy().get_event_loop() File "/usr/lib/python3.5/asyncio/events.py", line 578, in get_event_loop % threading.current_thread().name) RuntimeError: There is no current event loop in thread 'Thread-2'. So I tried to create the AsyncToSync inside the app.py as this gets executed by the main thread. By passing this instance I tried to execute the wrapper inside the signal handler. But this also doesn't work and the website is stuck loading. How can I get around this issue? -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Getting channels 2 to work
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.
John

Getting channels 2 to work
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
