I want my Django app 'popinion1' to communicate via textmessage with a local machine.

pip freeze :

asgi-redis==1.4.3

asgiref==2.3.2

async-timeout==3.0.1

autobahn==18.12.1

channels==2.1.3

daphne==2.2.4

Django==2.1.3

redis==2.10.6

Twisted==18.9.0

When I do "manage.py runserver" there seems to be a connection or at least no errors

However as soon as I refresh the browser in terminal I get:

• ERROR - ws_protocol - [Failure instance: Traceback: class'ValueError'>: No route found for path 'input/' [lots of lines]
  ending with: WebSocket DISCONNECT /input/ [127.0.0.1:50506]

with "/input/" being my app.
Firefox inspector reports:

Firefox can't establish connection to Server with ws://127.0.0.1:8000

/input/ being my app.

my routing.py is

from django.conf.urls import url

from channels.routing import ProtocolTypeRouter, URLRouter

from channels.auth import AuthMiddlewareStack

from channels.security.websocket import AllowedHostsOriginValidator, OriginValidator

from input.consumers import ChatConsumer





print('ChatConsumer: ', ChatConsumer.name)



application = ProtocolTypeRouter({

    'websocket': AllowedHostsOriginValidator(

        AuthMiddlewareStack(

            URLRouter(

                [

                    url(r'^input/(?P<username>[w.@+-]+)/$', ChatConsumer),

                ]

            )

        )

    )

})

the javascript in the html template:

<script>



    console.log(window.location)

    var loc = window.location

    var wsStart = 'ws://'

    if (loc.protocol == 'https:'){

        wsStart = 'wss://'

    }

    var endpoint = wsStart + loc.host + loc.pathname

    var socket = new WebSocket(endpoint)





    socket.onmessage = function(e){

        console.log("message", e)

    }

    socket.onopen= function(e){

        console.log("open", e)

    }

    socket.onerror= function(e){

        console.log("error", e)

    }

    socket.onclose= function(e){

        console.log("close", e)

    }

</script>

my consumers.py

import asyncio

import json

from django.contrib.auth import get_user_model

from channels.consumer import AsyncConsumer

from channels.db import database_sync_to_async

from .models import Thread, ChatMessage



from asgiref.sync import async_to_sync



class ChatConsumer(AsyncConsumer):

    name = 'ChatConsumer'



    async def websocket_connect(self, event):

        print('connected! ', event)

        await self.send({

            "type": "websocket.accept"

        })



    async def websocket_receive(self, event):

        print('receive! ', event)





    async def websocket_disconnect(self, event):

        print('disconnected! ', event)

CHANNEL_LAYERS in settings.py

CHANNEL_LAYERS = {

    'default': {

        'BACKEND': 'asgi_redis.core.RedisChannelLayer',

        'CONFIG': {

            'hosts': [('localhost', 6379)],

        },

        #'ROUTING': 'popinion_project.routing.channel_routing',

    }

}

so is it a wrong address in the routing.py? What's also weird is the last import of "ChatConsumer" in routing.py. It's "unresolved reference" but the print statement works.

print('ChatConsumer: ', ChatConsumer.name)

I'm following this tutorial

I'd be happy to know how to get the websocket to connect. Hopefully provided all necessary information. Thanks in advance
