List filters in admin interface
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|

|
||||
Prior to Django 1.4, the Django admin app allowed specifying change list

filters by specifying a field lookup (including spanning relations), and
|
||||
not custom filters. This has been rectified with a simple API previously

known as "FilterSpec" which was used internally. For more details, see the

documentation for :attr:`~django.contrib.admin.ModelAdmin.list_filter`.
