У меня есть базовое c Django приложение, которое я частично копирую из документов Django Rest Framework.
Проблема, с которой я столкнулся, заключалась в реализации обобщенного c на основе класса views Я получаю странную ошибку.
TypeError: as_view() takes 1 positional argument but 2 were given
Трассировка стека указывает на мой файл api/urls.py
и эту строку, где я определяю шаблоны URL:
path('', include(router.urls)),
Проект основан на api
со вторым приложением users
.
Единственное место, в котором реализован as_view()
, находится в users/urls.py
следующим образом:
from django.urls import path
from rest_framework.urlpatterns import format_suffix_patterns
from users import views
urlpatterns = [
path('users/', views.UserList.as_view()),
path('users/<int:pk>', views.UserDetail.as_view()),
]
urlpatterns = format_suffix_patterns(urlpatterns)
Какие аргументы должны быть там или что я неправильно настроил, что вызывает эту проблему?
views.py
from users.models import User
from users.serializers import UserSerializer
from rest_framework import generics
class UserList(generics.ListCreateAPIView):
"""
List all users or create a new user
"""
queryset = User.objects.all()
serializer_class = UserSerializer
@classmethod
def get_extra_actions(cls):
return []
class UserDetail(generics.RetrieveUpdateDestroyAPIView):
queryset = User.objects.all()
serializer_class = UserSerializer
api/urls.py
from django.contrib import admin
from django.urls import path, include
from rest_framework import routers
from users import views
router = routers.DefaultRouter()
router.register(r'users', views.UserList)
router.register(r'users', views.UserDetail)
urlpatterns = [
path('', include(router.urls)),
path('', include('users.urls')),
path('admin/', admin.site.urls),
path('api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]
