Question

我使用has_perm方法通过id获取用户时遇到问题。应该返回true，因为我使用

添加了

usr.user_permissions.add（p）

我刷新用户对象再次通过id获得，但仍然返回false。即使出现在管理员中也是如此。如果有人知道别的东西。在这里，我保留了部分设置，用户模型和使用的代码示例

class User(AbstractUser):

name = models.CharField(max_length=50)

email = models.EmailField(
    verbose_name='email address',
    max_length=255,
    unique=True,
)

USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['username']

def __str__(self):

************************代码示例*********************

url = reverse_lazy('user:list', kwargs={'id': self.kwargs['user']})
user_obj = User.objects.get(id =self.kwargs['user'])
perm = Permission.objects.get(id =self.kwargs['perm'])

if user_obj.has_perm(perm):
    print("removed")
    user_obj.user_permissions.remove(perm)
else:
    print("add")
    user_obj.user_permissions.add(perm)
success_message = "User perm changed"
return HttpResponseRedirect(url)

Django has_perm始终为false
