Django URL Filter provides a safe way to filter data via human-friendly URLs.

Overview

The main goal of Django URL Filter is to provide an easy URL interface for filtering data. It allows the user to safely filter by model attributes and also allows to specify the lookup type for each filter (very much like Django's filtering system in ORM).

For example the following will retrieve all items where the id is 5 and title contains "foo"::

example.com/listview/?id=5&title__contains=foo

In addition to basic lookup types, Django URL Filter allows to use more sophisticated lookups such as in or year. For example::

example.com/listview/?id__in=1,2,3&created__year=2013

Requirements

Installing

Easiest way to install this library is by using pip::

$ pip install django-url-filter

Usage Example

To make example short, it demonstrates Django URL Filter integration with Django REST Framework but it can be used without DRF (see below).

::

from url_filter.integrations.drf import DjangoFilterBackend

class UserViewSet(ModelViewSet): queryset = User.objects.all() serializer_class = UserSerializer filter_backends = [DjangoFilterBackend] filter_fields = ['username', 'email']

Alternatively filterset can be manually created and used directly to filter querysets::

from django.http import QueryDict from url_filter.filtersets import ModelFilterSet

class UserFilterSet(ModelFilterSet): class Meta(object): model = User

query = QueryDict('emailcontains=gmail&joinedgt=2015-01-01') fs = UserFilterSet(data=query, queryset=User.objects.all()) filtered_users = fs.filter()

Above will automatically allow the use of all of the Django URL Filter features. Some possibilities::

# get user with id 5
example.com/users/?id=5

# get user with id either 5, 10 or 15
example.com/users/?id__in=5,10,15

# get user with id between 5 and 10
example.com/users/?id__range=5,10

# get user with username "foo"
example.com/users/?username=foo

# get user with username containing case insensitive "foo"
example.com/users/?username__icontains=foo

# get user where username does NOT contain "foo"
example.com/users/?username__icontains!=foo

# get user who joined in 2015 as per user profile
example.com/users/?profile__joined__year=2015

# get user who joined in between 2010 and 2015 as per user profile
example.com/users/?profile__joined__range=2010-01-01,2015-12-31

# get user who joined in after 2010 as per user profile
example.com/users/?profile__joined__gt=2010-01-01
