静态文件使用Django渠道服务问题

我想我的手在这个例子中的WebSockets Django的，https://github.com/jacobian/channels-example因为我有打算用它我生产中的应用，以及其在Heroku的托管，并使用白噪声存在。因此，克隆上述例子后，我做了一些调整使用白噪声，但现在通过任何浏览器到应用程序第一次访问（铬或FF）的静态文件不加载，当我再次刷新加载静态文件，并在第三次加载它再次熄灭等。这里是我的设置文件：静态文件使用Django渠道服务问题

      'level': 'DEBUG', 
     }, 
    }, 
} 

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

这里是我做了修改routing.py其他文件：

from channels.staticfiles import StaticFilesConsumer 
from . import consumers 

channel_routing = { 
    # This makes Django serve static files from settings.STATIC_URL, similar 
    # to django.views.static.serve. This isn't ideal (not exactly production 
    # quality) but it works for a minimal example. 
    # 'http.request': StaticFilesConsumer(), 

    # Wire up websocket channels to our consumers: 
    'websocket.connect': consumers.ws_connect, 
    'websocket.receive': consumers.ws_receive, 
    'websocket.disconnect': consumers.ws_disconnect, 
}

Procfile是：

web: daphne chat.asgi:channel_layer --port $PORT --bind 0.0.0.0 -v2 
worker: python manage.py runworker -v2

我还没有尝试过在Heroku上好像现在，只需在本地主机上我观察到了这种行为，从而didnt甚至集成与原始应用程序的解决方案。我用heroku本地在本地运行应用程序。

我在做什么错？而在Procfile生产中提及的过程准备在Heroku？

尝试升级你的Django渠道1.0.3和3.3.0白噪声你提到的是使用过时的版本，其中添加到允许达芙妮服务与白噪声静态内容的一些bug修复的例子。或者你可以利用在S3存储服务的静态内容这是为Django的静态内容的首选方法。
