如何从令牌中检索用户 ID？

Question

有一个Plan具有用户字段的模型，我想用用户的令牌填充用户字段，以便用户无法发送用户id为另一个用户创建模型，而只是为自己发送发布请求，这是我的模型：class Plan(models.Model):"""Plan object"""user = models.ForeignKey(    settings.AUTH_USER_MODEL,    on_delete=models.CASCADE)我的观点是：class PlanViewSets(viewsets.ModelViewSet):"""A viewset for non-admin user see list and admin can curd plan model"""model = Planqueryset = Plan.objects.all().order_by('-id')serializer_class = serializers.PlanSerializerpermission_classes = (IsAuthenticated,)authentication_classes = (TokenAuthentication,)def get_queryset(self):    """retrieve plan just for its own user who is authenticated already"""    return self.queryset.filter(user=self.request.user)如何Plan只为用户创建而不user通过请求正文获取字段？

你想要的是perform_create方法：

class PlanViewSets(viewsets.ModelViewSet):

    """A viewset for non-admin user see list and admin can curd plan model"""

    model = Plan

    queryset = Plan.objects.all().order_by('-id')

    serializer_class = serializers.PlanSerializer

    permission_classes = (IsAuthenticated,)

    authentication_classes = (TokenAuthentication,)

    def get_queryset(self):

        """retrieve plan just for its own user who is authenticated already"""

        return self.queryset.filter(user=self.request.user)

    def perform_create(self, serializer):

        serializer.save(user=self.request.user)
