django channels on heroku hosting












1














Since I cant use redis I used the other channel layer that is
InMemoryChannelLayer



WSGI_APPLICATION = 'django_analytics.wsgi.application'

ASGI_APPLICATION = "django_analytics.routings.application"

CHANNEL_LAYERS = {

    "default": {

        "BACKEND": "channels.layers.InMemoryChannelLayer",

        "CONFIG": {

        },

    },

}


I deployed it, on heroku but I am getting error




(index):9 WebSocket connection to
'wss://mkmnim.herokuapp.com/ws/chat/page/' failed: Error during
WebSocket handshake: Unexpected response code: 404




I got it working at my local server but I am not able to do the same in hosting it online,Also will I have to do something related to daphne ?
Initially I used redis and ran redis server locally but while hosting redis setup was paid so I choose InMemoryChannelLayer
(channels without channel layer or any other free hosting)



so what should I do ?



django_analytics.routings.py



from channels.auth import AuthMiddlewareStack

from channels.routing import ProtocolTypeRouter, URLRouter

from view_analytics import routing



application = ProtocolTypeRouter({

    # Empty for now (http->django views is added by default)

    'websocket': AuthMiddlewareStack(

        URLRouter(

            routing.websocket_urlpatterns

        )

    ),

})


view_analytics.routings.py



from django.conf.urls import url



from . import consumers



websocket_urlpatterns = [

    url(r'^ws/chat/room/$', consumers.ChatConsumer),

    url(r'^ws/chat/page/$', consumers.PageConsumer),



]

    chatSocket.onmessage = function(e) {

        const data = JSON.parse(e.data);

        const message = data['message'];

        console.log("message is"+ message)

    };



    chatSocket.onclose = function(e) {

    };

  • Please clarify few details first. If this works in local then it will also works in heroku and it's nothing to do with InMemoryChannelLayer. Can you hard refresh your local browser and try to access the page in local server address?

Dulmage-Mendelsohn matrix decomposition in Python

Image
0 Matlab has a function called dmperm that computes the so-called Dulmage–Mendelsohn decomposition of a n x n matrix. From wikipedia, the Dulmage–Mendelsohn is a partition of the vertices of a bipartite graph into subsets, with the property that two adjacent vertices belong to the same subset if and only if they are paired with each other in a perfect matching of the graph. Looking both on scipy and numpy, I could not find this function, nor some similar version. Is it possible to implement it using basic linear algebra operations? Any idea if this is implemented in some Python package? python matlab linear-algebra graph-theory matrix-decomposition share | improve this question
