我已经创建了一个自定义的 Django 管理页面。我有两种类型的用户可以访问管理页面(员工用户和 super 用户)。 super 用户可以查看所有用户并可以更改他们的设置。他还可以添加或删除用户。员工用户只能看到他们的设置并且可以更改其中的一些设置。我目前有一个问题，员工用户可以看到 web 应用程序的所有用户，并可以添加或删除他们。我限制员工用户查看某些设置但无法更改。
我不知道如何限制员工用户只能看到他们的设置。
这是我的代码: 管理员.py

对于如何添加此功能的任何帮助或说明，我将不胜感激。
请您参考如下方法:
可以在admin类中设置 super 用户只有增删权限。
class UserAdmin(BaseUserAdmin):
...
def has_add_permission(self, request, obj=None):
return request.user.is_superuser
def has_delete_permission(self, request, obj=None):
return request.user.is_superuser
请注意，通过在管理界面中不向任何组或用户授予添加或删除权限也可以实现上述目的。
下面将只允许用户更改所有用户，如果他们是 super 用户。否则他们将只能更改自己的用户。
def has_change_permission(self, request, obj=None):
return request.user.is_superuser or (obj and obj.id == request.user.id)
如果您希望他们能够看到只有他们的用户可见的用户列表页面，您可以修改 get_queryset
def get_queryset(self, request):
qs = super().get_queryset(request)
user = request.user
return qs if user.is_superuser else qs.filter(id=user.id)
