Full documentation on read the docs.

Requirements

• Python 2.6+
• Django 1.4.5+

Installation

Install using pip:

pip install django-filter

Or clone the repo and add to your PYTHONPATH:

git clone git@github.com:alex/django-filter.git

Usage

Django-filter can be used for generating interfaces similar to the Django admin's list_filter interface. It has an API very similar to Django's ModelForms. For example, if you had a Product model you could have a filterset for it with the code:

import django_filters

class ProductFilter(django_filters.FilterSet):
    class Meta:
        model = Product
        fields = ['name', 'price', 'manufacturer']

And then in your view you could do:

def product_list(request):
    filter = ProductFilter(request.GET, queryset=Product.objects.all())
    return render_to_response('my_app/template.html', {'filter': filter})

Django-filters additionally supports specifying FilterSet fields using a dictionary to specify filters with lookup types:

import django_filters

class ProductFilter(django_filters.FilterSet):
    class Meta:
        model = Product
        fields = {'name': ['exact', 'icontains'],
                  'price': ['exact', 'gte', 'lte'],
                 }

The filters will be available as 'name', 'name__icontains', 'price', 'price__gte', and 'price__lte' in the above example.
