django channel set up routing -

-



i'm learning how setup websocket connection django-channel, i've got setup in routing.py 

from channels import route gallery import socket sock  channel_routing = [    # wire websocket channels our consumers:    route("websocket.connect", sock.ws_connect, path=r"^/render-status/$"),    route("websocket.receive", sock.ws_receive, , path=r"^/render-status/$"), ]

and following javascript 

// when we're using https, use wss too. var ws_scheme = window.location.protocol == "https:" ? "wss" : "ws"; var ws_path = ws_scheme + '://' + window.location.host + '/render-status/'; console.log("connecting " + ws_path) var socket = new reconnectingwebsocket(ws_path); socket.onmessage = function(message) {    console.log("got message: " + message.data);    var data = json.parse(message.data);    // if action started, add new item table    if (data.action == "started") {     }    // if action completed, update status    else if (data.action == "completed"){     } };  var message = {    action: "incomplete",    job_name: "10", }; socket.send(json.stringify(message));

tried out , there's failure in connecting (from console)

colorpicker2.js:565 connecting ws://127.0.0.1:8000/render-status/ reconnecting-websocket.min.js:1 uncaught domexception: failed execute 'send' on 'websocket': still in connecting state.     @ a.send (http://127.0.0.1:8000/static/js/reconnecting-websocket.min.js:1:2611)     @ htmldocument.<anonymous> (http://127.0.0.1:8000/static/js/colorpicker2.js:584:11)     @ k (http://127.0.0.1:8000/static/js/jquery.js:15:16962)     @ object.firewith [as resolvewith] (http://127.0.0.1:8000/static/js/jquery.js:15:17720)     @ function.ready (http://127.0.0.1:8000/static/js/jquery.js:15:12435)     @ htmldocument.d (http://127.0.0.1:8000/static/js/jquery.js:15:9840) send @ reconnecting-websocket.min.js:1 (anonymous) @ colorpicker2.js:584 k @ jquery.js:15 firewith @ jquery.js:15 ready @ jquery.js:15 d @ jquery.js:15 reconnecting-websocket.min.js:1 websocket connection 'ws://127.0.0.1:8000/render-status/' failed: error during websocket handshake: unexpected response code: 404 open @ reconnecting-websocket.min.js:1 @ reconnecting-websocket.min.js:1 (anonymous) @ colorpicker2.js:566 k @ jquery.js:15 firewith @ jquery.js:15 ready @ jquery.js:15 d @ jquery.js:15 22reconnecting-websocket.min.js:1 websocket connection 'ws://127.0.0.1:8000/render-status/' failed: error during websocket handshake: unexpected response code: 404 open @ reconnecting-websocket.min.js:1 (anonymous) @ reconnecting-websocket.min.js:1

i've checked documentation https://channels.readthedocs.io/en/stable/routing.html sure how set path.

your routing correct, sending message soon, while socket still trying connect. use onopen callback ensure message sent after connection established:

socket.onopen = function() {     var message = {         action: "incomplete",         job_name: "10",     };     socket.send(json.stringify(message)); }
