python - Django Rest API - 无法发出 PUT 或 DELETE 请求

Question

我有一个 django Rest API，想通过 Flutter 或 Postman 发出一个 put 请求。最终发生的事情是，当我发出 put 请求时，它会返回一个响应（看起来它已更改，打印出来），但实际上它从未真正更改过。这是我的代码！

class UserProfileView(viewsets.ModelViewSet):
queryset = UserProfile.objects.all()
serializer_class = UserProfileSerializer

class AssignmentView(viewsets.ModelViewSet):
queryset = Assignment.objects.all()
serializer_class = AssignmentSerializer

filter_backends = (
    django_filters.rest_framework.DjangoFilterBackend,
    rest_framework.filters.OrderingFilter, 
)
filter_fields = ['studyplan']

class UserAssignmentView(AssignmentView):
http_method_names = ['get', 'post', 'put', 'delete']
def get_queryset(self):
    return Assignment.objects.filter(canview__user=self.request.user)

def put(self, request, format=None):
    return Response({'received data': request.data})

def delete(self, request, format=None):
    return Response({'received data': request.data})


class StudyplanView(viewsets.ModelViewSet):
queryset = Studyplan.objects.all()
serializer_class = StudyplanSerializer

class UserStudyplanView(StudyplanView):
def get_queryset(self):
    return Studyplan.objects.filter(canview__user=self.request.user)

问题是您覆盖了两个put和delete方法，并且在它们内部什么都不做。尝试super()在其中调用方法：

class UserAssignmentView(AssignmentView):
    http_method_names = ['get', 'post', 'put', 'delete']
    def get_queryset(self):
        return Assignment.objects.filter(canview__user=self.request.user)

    def put(self, request, format=None):
        super().partial_update(request, format)
        return Response({'received data': request.data})

    def delete(self, request, format=None):
        super().destroy(request, format)
        return Response({'received data': request.data})
