缺少 1 个必需的位置参数：'request' django restframework

Question

我正在使用路由器创建 url，现在我想为我的 api 创建 url，但问题是，我收到错误

createuser() missing 1 required positional argument: 'request'missing 1 required positional argument: 'request'

我在 UserAuthAPIView class 中的所有方法都遇到了同样的错误，我已经阅读了关于 Whosebug 的解决方案，但它们在我的情况下不起作用。

我在 UserAuthAPIView class 中有很多方法，我想为所有这些方法创建 url。

例如

127.0.0.1:8000/api
127.0.0.1:8000/api/createuser
127.0.0.1:8000/api/login
127.0.0.1:8000/api/<pk>/viewuser

urls.py

from django.conf.urls import url
from UserAPI.api import views
from  UserAPI.api.views import UserAuthAPIView

urlpatterns = [
    url(r'^$', UserAuthAPIView.as_view({'get': 'list'}), name='user-list'),
    url(r'createuser/$', views.UserAuthAPIView.createuser, name='user-create'),
    #url(r'userlogin/$', views.UserAuthAPIView.userlogin, name='user-login'),
]

views.py

class UserAuthAPIView(ModelViewSet):
    queryset = UserModel.objects.all()
    serializer_class = ListViewSerializer

    def get_object(self, queryset=None):
        return self.request.user

    @action(methods=['post'], detail=False, permission_classes=[AllowAny], serializer_class=UserSerializer)
    def createuser(self, request, *args, **kwargs):
        data = request.data
        serializer = UserSerializer(data=data)
        if serializer.is_valid():
            serializer.save()
        return Response({ "status" : "user created successfully"}, status=HTTP_201_CREATED)

Answer 1

路由器在视图集上执行一些操作，特别是添加从 http 动词到相关函数的映射。

您需要为您的操作做类似的事情：

urlpatterns = [
    url(r'^$', UserAuthAPIView.as_view({'get': 'list'}), name='user-list'),
    url(r'createuser/$', views.UserAuthAPIView.as_view({'post': 'createuser'}), name='user-create'),
]

Answer 2

您在 url 中以错误的方式调用了 Viewset。你需要这样做：

router = routers.DefaultRouter()
router.register(r'auth', UserAuthAPIView)

urlpatterns = [
    url(r'^', include(router.urls)),
]

或

urlpatterns = [
    url(r'createuser/$', UserAuthAPIView.as_view({'post':'createuser'}),
]
