This code snippet demonstrates how to create custom actions in Django Admin to perform bulk updates on selected records. Specifically, it includes actions to mark users as active or inactive by updating the is_active field. These actions are integrated into the admin dropdown menu, allowing for efficient management of multiple records at once.

admin.py

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .models import Account
from django.utils.translation import ngettext
from django.contrib import messages


class UserAdmin(admin.ModelAdmin):
    actions = ('mark_as_active', 'mark_as_inactive')  # Add your actions here
    list_display = (
        "username",
        "email",
        full_name,
        "is_active",
    )
    list_filter = (
        "is_staff",
        "is_superuser",
    )

    def mark_as_active(self, request, queryset):
        updated = queryset.update(is_active=True)  # Bulk update
        self.message_user(
            request, 
            ngettext(
                '%d User was successfully marked as Active.',
                '%d Users were successfully marked as Active.',
                updated,
            ) % updated,
            messages.SUCCESS
        )

    def mark_as_inactive(self, request, queryset):
        updated = queryset.update(is_active=False)  # Bulk update
        self.message_user(
            request, 
            ngettext(
                '%d User was successfully marked as Inactive.',
                '%d Users were successfully marked as Inactive.',
                updated,
            ) % updated,
            messages.SUCCESS
        )

admin.site.register(Account, AccountAdminConfig)
