我正在开发一个基本的Django DRF API . 我一直在使用带有显式网址的基于类的视图 . 现在我正在尝试使用非常普通的DRF ViewSets路由器（用于自动生成URL） .
任何人都可以帮我指出正确的方向吗？我在DRF 3.8和Django 2.0上
项目urls.py：
from django.conf.urls import url, include
urlpatterns = [
url(r'^userprofile/', include('UserProfile.urls', namespace='UserProfile')),
]
App：UserProfile / urls.py：
from django.conf.urls import include
from django.urls import path
from rest_framework.routers import DefaultRouter
from UserProfile import views
app_name = 'UserProfile'
router = DefaultRouter()
router.register('humans', views.HumanViewSet,)
urlpatterns = [path('', include(router.urls))]
App：UserProfile / views.py
from rest_framework import viewsets
from UserProfile.models import Human
from UserProfile.serializers import HumanSerializer
class HumanViewSet(viewsets.ReadOnlyModelViewSet):
serializer_class = HumanSerializer
queryset = Human.objects.all()
我收到一个错误：
__init__() missing 2 required positional arguments: 'app_name' and 'app_module'
