django-adminfilters

A collection of FieldListFilters for object list filtering in the django administrator.

Multiple selection filters allow filtering on one or more filter values. The following multiple selection filters are available:

• UnionFieldListFilter: filters results matching ANY of the filter values. Similar to the Union operation on sets.
• IntersectionFieldListFilter: filters results maching ALL of the filter values. Similar to the Intersection operation on sets.

How to use

Import the filter and add it as a FieldListFilter implementation to the list_filter attribute of a ModelAdmin as described in the Django Documentation <https://docs.djangoproject.com/en/1.4/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_filter>_.

::

from extraadminfilters.filters import UnionFieldListFilter

class CountryAdmin(admin.ModelAdmin):
    list_filter = (
        ('continent', UnionFieldListFilter),
        'languages'
    )
