Infinite Pagination for Django

This is a very simple helper for Django 1.4 that does one thing: efficiently paginates large object collections on systems where using standard Django Paginator is impractical because of significant count(*) query overhead (i.e. PostgreSQL).

Under the hood it uses a single query to retrieve objects for the current page and check for availability of a successive page.

The InfinitePaginator is a replacement for Django django.core.paginator.Paginator.

Quick Start

Include django-infinite-pagination in your requirements file (or pip install django-infinite-pagination) and add infinite_pagination to INSTALLED APPS.

Then set the paginator_class attribute of your ListView-based view to InfinitePaginator and specify paginate_by attribute::

class ArticleListView(ListView):
    model = Article
    paginate_by = 10
    paginator_class = InfinitePaginator

To display pagination links in a template load the infinite_pagination template tags and put {% paginate %} in the place you would like the pagination links to show up::

{% load infinite_pagination %}

{% for object in object_list %}
    {{ object }}
{% endfor %}

{% paginate %}

A generic pagination/infinite_pagination.html template that works well with Twitter Bootstrap stylesheet is provided by this application. Adjust it to your requirements.

Paginating in Templates

Sometimes application views cannot be modified and the pagination can only be done at the template level. The autopaginate template tag is provided as a last resort of applying pagination to object lists inside templates::

{% load infinite_pagination %}

{% autopaginate object_list per_page=10 as paginated_list %}

{% for object in paginated_list %}
    {{ object }}
{% endfor %}

{% paginate %}

The autopaginate tag takes a queryset and a number of items per page as input and returns a page slice for displaying in a template. Current page number is retrieved from template context or page request GET params. It can also be specified as an optional tag param::

{% autopaginate object_list per_page=10 page=2 as paginated_list %}

The tag also sets paginator and page_obj template context variables for the paginate tag that uses them to render navigation links.
