How to fix AttributeError: 'ASGIRequest' object has no attribute 'accept' error?

Question

Django

Please help me figure out the error. Created a web application with django. I connected web sockets according to the instructions ( https://alex-oleshkevich.medium.com/websockets-in-... ).
When the web application starts, it connects to web sockets using js ( ws://localhost/websocket/ ). Actually, an error occurs during the websocket.accept event:

Internal Server Error: /websocket/
Traceback (most recent call last):
  File "/home/pi/microwire/venv/lib/python3.7/site-packages/asgiref/sync.py", line 458, in thread_handler
    raise exc_info[1]

    response = await get_response(request)

  File "./app/views.py", line 76, in websocket
    await socket.accept()

websocket = path

urlpatterns = [
    websocket('websocket/', views.websocket),
    path('', views.index)
