我得到“详细信息”：“未找到。” 当我访问此链接 localhost:8000/portal/finalyears/1/members/2 但当我使用以下链接时，它会显示详细信息： localhost:8000/portal/finalyears/1/members/1

我的 urls.py 文件包含：

    path('finalyears/<int:pk>/members/<int:id>', MemberDetailView.as_view(), name='Members_Detail'),

模型“成员”如下所示：

class Member(models.Model):
    finalyear = models.ForeignKey(to=FYP, on_delete=models.CASCADE)
    Student_Id = models.ForeignKey(to=Student, on_delete=models.CASCADE)
    Leader_FYP = models.BooleanField(default=False)

    class Meta:
        verbose_name_plural = 'Members'

    def __str__(self):
        return '{}'.format(self.finalyear)

API.py 包含：

class MemberDetailView(generics.RetrieveUpdateDestroyAPIView):
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]
    # lookup_field = "member_pk"

    def get_queryset(self):
        fyp = self.kwargs['pk']
        member = self.kwargs['id']
        return Member.objects.filter(finalyear=fyp,  id=member)

    serializer_class = MemberSerializer

我可以通过以下代码打印数据

from PortalAPI.serializers import MemberSerializer
from PortalAPI.models import Member

for a in Member.objects.filter(finalyear=1, id=2):
...     MemberSerializer(a).data
