Django Filter

Django-filter is a reusable Django application allowing users to declaratively add dynamic QuerySet filtering from URL parameters.

Full documentation on read the docs.

Requirements

Python: 3.4, 3.5, 3.6, 3.7
Django: 1.11, 2.0, 2.1, 2.2
DRF: 3.8+

From Version 2.0 Django Filter is Python 3 only. If you need to support Python 2.7 use the version 1.1 release.

Installation

Install using pip:

pip install django-filter

Then add 'django_filters' to your INSTALLED_APPS.

INSTALLED_APPS = [
    ...
    'django_filters',
]

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})

Usage with Django REST Framework

Django-filter provides a custom FilterSet and filter backend for use with Django REST Framework.

To use this adjust your import to use django_filters.rest_framework.FilterSet.

from django_filters import rest_framework as filters

class ProductFilter(filters.FilterSet):
    class Meta:
        model = Product
        fields = ('category', 'in_stock')
