Django suit admin inline pagination
When you have a lot of inline objects, pagination will be a good way to make page of item lighter. You can implement it by yourself. Also keep in mind for Django 1.5 and Django 1.6 implementations differ.
Also currently this code doesn’t support multiple inlines per page, but it can be easy implemented.
Consider this code as a proof of concept, not final code.
Usage:
- Copy tabular_paginated.html to one of your template directories under admin/edit_inline/ path
- Use PaginationInline class as base class for your TabularInline
After you setup classes it should look like this:
You need to remove
visibility:hidden
from
.form-horizontal .suit-tab
Template file:
templates/admin/edit_inline/tabular_paginated.html
{% load i18n suit_list %} {% include 'admin/edit_inline/tabular.html' %} {% block after_inline %} <div class="suit-tab suit-tab-relations"> {% with inline_admin_formset.formset.cl as cl %} {% if cl.paginator %} {% pagination cl %} {% endif %} {% endwith %} </div> {# Following javaScript is required if you have tabs, otherwise you can remove this JS code #} <script type="text/javascript"> (function ($) { Suit.$('.pagination li a').on('click', function () { if (document.location.hash) { $(this).attr('href', $(this).attr('href') + '#' + document.location.hash.substr(1)); } }); }(Suit.$)); </script> {% endblock %}
