Override delete_selected in Django admin

gistfile1.py

from django.core.exceptions import PermissionDenied
from django.contrib import admin
from django.contrib.admin.actions import delete_selected as delete_selected_


def delete_selected(modeladmin, request, queryset):
    if not modeladmin.has_delete_permission(request):
        raise PermissionDenied
    if request.POST.get('post'):
        for obj in queryset:
            obj.delete()
    else:
        return delete_selected_(modeladmin, request, queryset)
delete_selected.short_description = "Delete selected objects"


class MyModelAdmin(admin.ModelAdmin):
    actions = [delete_selected]

How to override that in Django 2?

Hi,

I have got the problem with my exercise where I have to block ability superuser to delete other superuser and himself.

admin.py
`def delete_selected(modeladmin, request, queryset):
    if not modeladmin.has_delete_permission(request):
        raise PermissionDenied
    if request.POST.get('post'):
        for obj in queryset:
            if not obj.is_superuser:
                obj.delete()
    else:
        return delete_selected_(modeladmin, request, queryset)
delete_selected.short_description = "Delete selected objects"

and url.py

path("admin/auth/user/",delete_selected), `
