Question

我正在尝试使用https://github.com/arneb/django-messages并按照以下说明进行操作

pip install django-messages

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'rest_framework',
    'rest_framework.authtoken',
    'oauth2_provider',
    'api',
    'localflavor',
    'django_localflavor_us',
    'django_countries',
    'haystack',
    'django_messages',

]


urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', include('api.urls')),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
    url(r'^messages/', include('django_messages.urls')),
]

当我登录django shell并尝试以下

时

In [1]: from django_messages.models import Message

In [2]: Message.objects.all()
Out[2]: <QuerySet []>

它工作正常，我可以导入消息模型，但当我尝试在管理员注册它时，它说的是以下错误

from django.contrib import admin
from django_messages.models import Message
admin.site.register(Message)

错误：

问题是什么以及如何解决？
