我有一个视图，它在向端点发送POST请求时创建一个post。

class PostViewSet(viewsets.ModelViewSet):
          serializer_class = PostSerializer
          queryset = Post.objects.all()
          permission_classes = [IsAuthorOrReadOnly]
          def create(self, request, *args, **kwargs):
               serializer = self.get_serializer(data=request.data)
                user = request.user
                if serializer.is_valid():
                     serializer.save(author=user)
                     return Response(data=serializer.data, status=status.HTTP_201_CREATED)
                return Response(errors=serializer.errors, status=status.HTTP_400_BAD_REQUEST)
