Paginator for PostgreSQL

Use this paginator to make admin pages load more quickly for large tables when using PostgreSQL. It uses the reltuples statistic instead of counting the rows when there is no where clause. To use this code, add the following in your admin: `class BigTableAdmin(admin.ModelAdmin): paginator = LargeTablePaginator def get_changelist(self, request, **kwargs): return LargeTableChangeList `

Digg-like paginator, updated

Ellipsis paginator decorator with first and last two items

Use this template tag to get a paginator showing the first and last two pages w/ adjacent pages using ellipsis. The `page` parameter is a page of a `Paginator` (typically the first but you can use whichever you want). In case of 50 pages, while being on the 40th, it'll give you the following iterable of `int`s (with `settings.PAGINATOR_ADJACENT_PAGES = 2`): `(1, 2,    38, 39, 40, 41, 42,    49, 50) ` You get the idea.

Simple Paginate

This function wraps boilerplate code to get the current page in a view, obtaining the page number from some URL query string variable, e.g., ?page=2 The interface is inspired by the interface of Paginator. The implementation follows an example given in Django documentation.

Digg-like pagination

My take on digg-like pagination. Save the code as 'templatetags/pagination_nav.py' in one of your apps. It relies on a 'pagination_nav.html' template. Here is a base template: {% if pages %} <div class="bottom-pagination-nav"> {% if previous_url %}<a href="{{ previous_url }}">{% else %}<span>{% endif %}&laquo; Previous{% if previous_url %}</a>{% else %}</span>{% endif %} {% for group in pages %} {% for page in group %} {% if page.current %}<span>{{ page.number }}</span>{% else %}<a href="{{ page.url }}">{{ page.number }}</a>{% endif %} {% endfor %} {% if not forloop.last %}<span>...</span>{% endif %} {% endfor %} {% if next_url %}<a href="{{ next_url }}">{% else %}<span>{% endif %}Next &raquo;{% if next_url %}</a>{% else %}</span>{% endif %} </div> {% endif %}

Pagination/Filtering Alphabetically

This allows you to create an alphabetical filter for a list of objects; e.g. `Browse by title: A-G H-N O-Z`. See [this entry](http://developer.yahoo.com/ypatterns/pattern.php?pattern=alphafilterlinks) in Yahoo's design pattern library for more info. NamePaginator works like Django's Paginator. You pass in a list of objects and how many you want per letter range ("page"). Then, it will dynamically generate the "pages" so that there are approximately `per_page` objects per page. By dynamically generating the letter ranges, you avoid having too many objects in some letter ranges and too few in some. If your list is heavy on one end of the letter range, there will be more pages for that range. It splits the pages on letter boundaries, so not all the pages will have exactly `per_page` objects. However, it will decide to overflow or underflow depending on which is closer to `per_page`. **NamePaginator Arguments**: `object_list`: A list, dictionary, QuerySet, or something similar. `on`: If you specified a QuerySet, this is the field it will paginate on. In the example below, we're paginating a list of Contact objects, but the `Contact.email` string is what will be used in filtering. `per_page`: How many items you want per page. **Examples:** >>> paginator = NamePaginator(Contacts.objects.all(), \ ... on="email", per_page=10) >>> paginator.num_pages 4 >>> paginator.pages [A, B-R, S-T, U-Z] >>> paginator.count 36 >>> page = paginator.page(2) >>> page 'B-R' >>> page.start_letter 'B' >>> page.end_letter 'R' >>> page.number 2 >>> page.count 8 In your view, you have something like: contact_list = Contacts.objects.all() paginator = NamePaginator(contact_list, \ on="first_name", per_page=25) try: page = int(request.GET.get('page', '1')) except ValueError: page = 1 try: page = paginator.page(page) except (InvalidPage): page = paginator.page(paginator.num_pages) return render_to_response('list.html', {"page": page}) In your template, have something like: {% for object in page.object_list %} ... {% endfor %} <div class="pagination"> Browse by title: {% for p in page.paginator.pages %} {% if p == page %} <span class="selected">{{ page }}</span> {% else %} <a href="?page={{ page.number }}"> {{ page }} </a> {% endif %} {% endfor %} </div> It currently only supports paginating on alphabets (not alphanumeric) and will throw an exception if any of the strings it is paginating on are blank. You can fix either of those shortcomings pretty easily, though.

yet another digg style paginator

put this code into your application's `__init__.py` it adds a mixin to the `Paginator` class that implements a digg style pagination. the mixin has just one method called `digg_page_range` that takes the current page object as the parameter. this method is an iterator which yields page numbers with `None` values representing gaps. this iterator is similar to the original paginator's method `page_range` and it can be used in your code to emit the needed markup.

Stateful paginator, digg style

**This code will throw deprecation warnings in newer Django checkouts - see the http://www.djangosnippets.org/snippets/773/ for an improved version that should work with the recent trunk.** objects = MyModel.objects.all() paginator = DiggPaginator(objects, 10, body=6, padding=2, page=7) return render_to_response('template.html', {'paginator': paginator} {% if paginator.has_next %}{# pagelink paginator.next #}{% endif %} {% for page in paginator.page_range %} {% if not page %} ... {% else %}{# pagelink page #} {% endif %} {% endfor %} http://blog.elsdoerfer.name/2008/03/06/yet-another-paginator-digg-style/
