应用程序内部异常：找不到路径 'ws/chat/room/2/'

Question

Django 频道问题。请帮助。

路由.py

websocket_urlpatterns = [
    url(r'ws/chat/room/(?P<room_id>\d+)/$', ChatConsumer.as_asgi()),]

room.html

var chatSocket = new WebSocket(
            'ws://' + window.location.host +
            '/ws/chat/room/{{ room.id }}/'
        );

项目名称/urls.py

    path('chat/', include('chat.urls', namespace='chat')),

聊天/urls.py

    path('room/<int:room_id>/', views.room, name='room'),
    path('room/<int:room_id>/send_message/', views.send_message, name='send_message'),

websocket.url =

ws://127.0.0.1:8000/ws/chat/room/2/

Exception inside application: No route found for path 'ws/chat/room/2'.

多次更改 re_path，要求 chatgpt 编写新的 html 模板（我更喜欢 Django，然后是 JS）。
