python - 覆盖 django rest 泛型 CreateAPIView 中的创建方法

Question

我的 Django 应用程序的 views.py 如下，

class MemberCreate(generics.CreateAPIView):
    queryset = members.objects.all()
    serializer_class = MemberSerializer
    permission_classes = (permissions.IsAdminUser,)

    def create(self, serializer):
        ''' I wanted to do some stuff with serializer.data here '''
        pass 

在上面，如果我覆盖 create 函数，返回失败并出现以下错误，即使我不做任何事情并且只是写通过它也会失败，

AssertionError: Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'NoneType'>`

Answer 1

返回应该是 instanceof Response .您可以返回parent类回复，在您的 stuff 之后

def create(self, request, *args, **kwargs):
    ''' I wanted to do some stuff with serializer.data here '''
    return super(MemberCreate, self).create(request, *args, **kwargs)

否则，如果您不想要父响应，则只需返回 Response实例

def create(self, request, *args, **kwargs):
    ''' I wanted to do some stuff with serializer.data here '''
    return Response(status=204)
