channels_presence.models.Presence runtimeError

Question

这是我第一次用Django实现Websockets，我正在努力做到这一点。

每次尝试运行服务器时，我都会收到这个错误：RuntimeError: Model class channels_presence.models.Presence doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

我的settings.py：

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'votemanager',
'roommanager',
'rest_framework',
'multiselectfield',
'django_filters',
'channels',
]

CHANNEL_LAYERS = {
"default": {
    "BACKEND": "channels.layers.InMemoryChannelLayer"
}
}

有人能帮我吗？

Answer 1

将channel_presense添加到INSTALLED_APPS中，以便Django能够识别channel_present应用程序，然后可以使用channels_presence.models.Presence
