DJANGO REST框架：使用Generics Apiview I＆＃x27; M无法设置权限（Permissions.Py不适合个人用户）

Question

我希望管理员用户能够访问每个用户详细信息和非ADMIN用户仅访问其自己的详细信息，但是而不是此非ADMIN用户在实现此过程时显示与管理用户相同的每个用户的完整列表。当我分享了我的Views.py，Permissions.py和Models.py时。

我不确定问题是否在persions..py.py或models.py中，因为我是Django的新手。

我正在使用Postman进行API测试，这对管理员用户来说很好，但是对于单个用户而言，它无法正常工作。

views.py


class UserListCreateAPIView(generics.ListCreateAPIView):
    permission_classes = [IsStaffOrTargetUser]
    queryset = User.objects.all()
    serializer_class = UserSerializer


class UserRetrtieveUpdateDestroyAPIView(generics.RetrieveUpdateDestroyAPIView):
    permission_classes = [IsStaffOrTargetUser]
    queryset = User.objects.all()
    
    serializer_class = UserSerializer

permissions.py

class IsStaffOrTargetUser(BasePermission):
    def has_permission(self, request, view):
        # allow user to list all users if logged in user is staff
        return request.user or request.user.is_staff
 
    def has_object_permission(self, request, view, obj):
        # allow logged in user to view own details, allows staff to view all records
        return request.user.is_staff or obj == request.user

models.py

class User(AbstractBaseUser):
    email = models.EmailField(verbose_name='Email',max_length=255,unique=True)
    name = models.CharField(max_length=200)
    contact_number= models.IntegerField()
    gender = models.IntegerField(choices=GENDER_CHOICES)
    address= models.CharField(max_length=100)
    state=models.CharField(max_length=100)
    city=models.CharField(max_length=100)
    country=models.CharField(max_length=100)
    pincode= models.IntegerField()
    dob = models.DateField(null= True)


    # is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    objects = UserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['name','contact_number','gender','address','state','city','country','pincode','dob']

    def __str__(self):
        return self.email

    def has_perm(self, perm, obj=None):
        "Does the user have a specific permission?"
        # Simplest possible answer: Yes, always
        return self.is_admin

    def has_module_perms(self, app_label):
        "Does the user have permissions to view the app `app_label`?"
        # Simplest possible answer: Yes, always
        return True

    @property
    def is_staff(self):
        "Is the user a member of staff?"
        # Simplest possible answer: All admins are staff
        return self.is_admin
