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]

Great gist, thanks.
I don't understand the "if request.POST.get('post'):" condition. Where does the 'post' POST parameter come from. I use this gist without this condition like that:

def delete_selected(modeladmin, request, queryset):
    if not modeladmin.has_delete_permission(request, queryset=queryset):
        raise PermissionDenied
    for obj in queryset:
        obj.delete()

delete_selected.short_description = "Delete selected objects"

Thanks for the answers.

@boehlke your code has an error:
has_delete_permission can not pass queryset argument, otherwise it will raise TypeError

https://docs.djangoproject.com/en/1.7/ref/contrib/admin/#django.contrib.admin.ModelAdmin.has_delete_permission

@boehike Look at the django.contrib.admin.actions.delete_selected. The 'post' parameter is set in the confirmation page (that confirms the deletion of related objects)

you are not overriding, you are creating a custom method and replacing the default function.
Overriding will keep all functionality of default function and only changed the part you wanted to change.
This one for example will remove the intermediate step of warning (this action will delete
and will replace specific short description should be Delete selected <> to a generic delete selected objects

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), `
