How to send signals to consumer in django? - django

Question

I'm developing WebSocket programs in Django. I want to receive the request from the client(ReactJS) and send signals to WebSocket consumer, and then WebSocket consumer sends messages to the client.
How to solve such a problem?
I tried as following.
urls.py
urlpatterns = [
url(r'^updatesignal/$',updatesignal),
url(r'^stopsignal/$',stopsignal),
]
views.py
#api_view(['POST'])
def updatesignal(request):
print("update")
consumers.isconnected = 1
return Response("update signal")
#api_view(['POST'])
def stopsignal(request):
print("stop signal")
consumers.isconnected = 0
return Response("stop signal")
consumers.py
from channels.generic.websocket import AsyncWebsocketConsumer
import json
import asyncio
isconnected = 0
class ChatConsumer(AsyncWebsocketConsumer):
async def connect(self):
print("connect")
await self.accept()
while isconnected == 1:
await asyncio.sleep(2)
print("true")
# obj = # do_something (Ex: constantly query DB...)
await self.send(text_data=json.dumps({
'message': "aaa"
}))
async def disconnect(self, close_code):
# Leave room group
pass
async def receive(self, text_data):
# Receive message from WebSocket
.....
But WebSocket consumer is fired after 10 seconds after receiving update signal request. How to solve this problem?
