Requirements

  • Python 2.7, 3.3, 3.4, 3.5
  • Django 1.8, 1.9, 1.10
  • DRF 3.3 (Django 1.8 only), 3.4

Installation

Install using pip:

pip install django-filter

Or clone the repo and add to your PYTHONPATH:

git clone git@github.com:carltongibson/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(request, '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.
