DO NOT USE has_delete_permission() override as it is not being called on every object when you perform delete action from changelist.

不要使用has_delete_permission（）覆盖，因为当您从更改列表执行删除操作时，不会在每个对象上调用它。

Use signals to do it. Add this to any models.py

使用信号来做到这一点。将其添加到任何models.py中

from django.db.models.signals import pre_delete
from django.dispatch.dispatcher import receiver
from django.contrib.auth.models import User
from django.core.exceptions import PermissionDenied

@receiver(pre_delete, sender=User)
def delete_user(sender, instance, **kwargs):
    if instance.is_superuser:
        raise PermissionDenied

The only drawback of this method is that nobody will be able to delete any super user. You will have to set users attribute "is_superuser" to False before you can delete it.

这种方法的唯一缺点是没有人能够删除任何超级用户。在删除之前，您必须将用户属性“is_superuser”设置为False。

You can try to override UserAdmin so that it won't allow deleting as documented here:

您可以尝试覆盖UserAdmin，以便它不允许删除，如下所示：

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User

class MyUserAdmin(UserAdmin):

    def has_delete_permission(self, request, obj=None):
       if obj is None:
           return True
       else:
           return not obj.is_superuser

admin.site.unregister(User)
admin.site.register(User, MyUserAdmin)
