Mixing
Websocket disconnect with Channels in Django
1
I'm beginner with Django. I would like to use websockets with Channels. In this way I'm following this tutorial to create a simple chat.
I show you my files.
chat/consumers.py
from channels.generic.websocket import WebsocketConsumer
import json
class ChatConsumer(WebsocketConsumer):
def connect(self):
self.accept()
def disconnect(self, close_code):
pass
def receive(self, text_data):
text_data_json = json.loads(text_data)
message = text_data_json['message']
self.send(text_data=json.dumps({
'message': message
}))
My template file room.html :
<!-- chat/templates/chat/room.html -->
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>Chat Room</title>
</head>
<body>
<textarea id="chat-log" cols="100" rows="20"></textarea><br/>
<input id="chat-message-input" type="text" size="100"/><br/>
<input id="chat-message-submit" type="button" value="Send"/>
</body>
<script>
var roomName = {{ room_name_json }};
var chatSocket = new WebSocket(
'ws://' + window.location.host +
'/ws/chat/' + roomName + '/');
chatSocket.onmessage = function(e) {
var data = JSON.parse(e.data);
var message = data['message'];
document.querySelector('#chat-log').value += (message + 'n');
};
chatSocket.onclose = function(e) {
console.error('Chat socket closed unexpectedly');
};
document.querySelector('#chat-message-input').focus();
document.querySelector('#chat-message-input').onkeyup = function(e) {
if (e.keyCode === 13) { // enter, return
document.querySelector('#chat-message-submit').click();
}
};
document.querySelector('#chat-message-submit').onclick = function(e) {
var messageInputDom = document.querySelector('#chat-message-input');
var message = messageInputDom.value;
chatSocket.send(JSON.stringify({
'message': message
}));
messageInputDom.value = '';
};
</script>
</html>
Root routing configuration :
# mysite/routing.py
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
import chat.routing
application = ProtocolTypeRouter({
# (http->django views is added by default)
'websocket': AuthMiddlewareStack(
URLRouter(
chat.routing.websocket_urlpatterns
)
),
})
And my routing.py file :
# chat/routing.py
from django.conf.urls import url
from . import consumers
websocket_urlpatterns = [
url(r'^ws/chat/(?P<room_name>[^/]+)/$', consumers.ChatConsumer),
]
When I run my ASGI server and I arrive on the page http://127.0.0.1:8000/chat/Test/, I'm getting the following message error :
HTTP GET /chat/Test/ 200 [0.00, 127.0.0.1:2807]

]
WebSocket DISCONNECT /ws/chat/Test/ [127.0.0.1:2814]
Would you have an idea of the problem ? :)
This question is similar, but no answer has been provided.
Thank you !
EDIT
I notice a strange thing, if I put wrong code in my file routing.py, the server doesn't notice it. It is like it doesn't read this file. For example if I turn the routing.py file like this :
# chat/routing.py
from django.conf.urls import url
from . import consumers
websocket_urlpatterns = [
url(r'^ws/chat/(?P<room_name>[^/]+)/$', consumers.ChatConsumer),ezvzev
]
The server doesn't display any error message.
