separate http requests between channels routing and "classic django routing

[Kevin Tewouda]

Hello,

i am developing an application (a REST one) which have to serve some sse events to a web application. I saw in the latest documentation how to create an SSE consumer, but now when i create an http routing for consumers, i can't serve the others requests using the "classic django view system". So my question is how can i separate the sse routing from the other http requests to have all of this working properly.

Thanks in advance for your suggestions.

Best regards

You can just use channels.http.AsgiHandler as the consumer/ASGI app to hand off to Django views. It's mentioned in the last paragraph here: http://channels.readthedocs.io/en/latest/topics/routing.html#protocoltyperouter

Thanks Andrew
i found the mistake myself, my routing file was like this

http_urlpatterns = [
    path('stream', ServerSentEventsConsumer),
    path('', AsgiHandler)
]

I think that the second route will match all the default routes, but like it is mentionned in the tutorial, we have to use a regex path. So i change it to this and it works nice!

http_urlpatterns = [
    path('stream', ServerSentEventsConsumer),
    re_path(r'', AsgiHandler)
]

I think there should be a warning in the tutorial to take particular attention with the path method introduced in django 2.

Thanks again.

Ah, yes, there is a bug with URLRouter and path() where it will auto-add a $ to the regex it generates as it doesn't think the right-hand side is an include. This is likely something I need to patch in Django itself, but until then I suggest using re_path in any case where you want to match just a prefix.
