Django Rest API-無法發出PUT或DELETE請求

Question

我有django Rest API，想通過Flutter或Postman發出放置請求。 最終發生的事情是，當我發出放置請求時，它返回一個響應（看起來好像已更改，已打印出），但實際上它從未真正更改過。 這是我的代碼！

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)

問題是您同時覆蓋了put和delete方法，並且在其中不執行任何操作。 嘗試在其中調用super()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})
