Django Lazy Admin Pagination

django-lazy-admin-pagination is a Django package designed to provide lazy-loading pagination for Django's admin interface. It enhances user experience by loading total counts asynchronously and updating pagination dynamically, improving performance on large datasets.

Features

• Lazy-loaded total count: Avoids counting total records during initial page load, improving performance.
• Dynamic pagination controls: Updated via AJAX to reflect the correct number of pages.
• Compatible with Django's standard admin interface.

Installation

Step 1: Install the Package

You can install the package directly from GitHub or PyPI:

Install from GitHub:

pip install git+https://github.com/anish5256/django-lazy-admin-pagination.git

Step 2: Add to INSTALLED_APPS

Add django_lazy_admin_pagination to the INSTALLED_APPS list in your Django project's settings.py file:

INSTALLED_APPS = [
    ...,
    'django_admin_lazy_count',
]

Usage

Step 1: Import and Use LazyLoadPaginationMixin

In your admin.py, modify your model admin class to include LazyLoadPaginationMixin.

from django.contrib import admin
from django_admin_lazy_count.main import LazyLoadPaginationMixin
from .models import YourModel

@admin.register(YourModel)
class YourModelAdmin(LazyLoadPaginationMixin, admin.ModelAdmin):
    list_per_page = 100  # Customize the number of items per page as needed

Example Project Setup

Here's an example admin.py configuration for a Django project using the package:

# admin.py
from django.contrib import admin
from django_lazy_admin_pagination.main import LazyLoadPaginationMixin
from .models import Product

@admin.register(Product)
class ProductAdmin(LazyLoadPaginationMixin, admin.ModelAdmin):
    list_display = ('name', 'price', 'stock')
    search_fields = ('name', 'description')
    list_filter = ('category',)
    list_per_page = 50

Explanation of the Code

• LazyLoadPaginationMixin: This mixin adds lazy-loading pagination functionality to the admin class.
• list_per_page: Specifies the number of items displayed per page. Adjust this value as needed.

How It Works

1. Initial Load: The page loads with basic pagination controls, including "Previous" and "Next" buttons, while showing "Count is loading..."
2. AJAX Call: A JavaScript function makes an AJAX call to fetch the total count and updates the pagination controls once the data is received.
3. Dynamic Update: The pagination controls are updated to reflect the total number of pages, and the count is displayed in the admin search form.
