Versioning and stability policy
-------------------------------
Django-Filter is a mature and stable package. It uses a two-part CalVer
versioning scheme, such as ``21.1.1``. The first number is the year. The second
is the release number within that year.
On an on-going basis, Django-Filter aims to support all current Django
versions, the matching current Python versions, and the latest version of
Django REST Framework.
Please see:
* `Status of supported Python branches <https://devguide.python.org/#status-of-python-branches>`_
* `List of supported Django versions <https://www.djangoproject.com/download/#support-versions>`_
Support for Python and Django versions will be dropped when they reach
end-of-life. Support for Python versions will dropped when they reach
end-of-life, even when still supported by a current version of Django.
Other breaking changes are rare. Where required, every effort will be made to
apply a "Year plus two" deprecation period. For example, a change initially
introduced in ``23.x`` would offer a fallback where feasible and finally be
removed in ``25.1``. Where fallbacks are not feasible, breaking changes without
deprecation will be called out in the release notes.
Installation
------------
Install using pip:
.. code-block:: sh
pip install django-filter
Then add ``'django_filters'`` to your ``INSTALLED_APPS``.
.. code-block:: python
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:
.. code-block:: python
import django_filters
class ProductFilter(django_filters.FilterSet):
class Meta:
model = Product
fields = ['name', 'price', 'manufacturer']
And then in your view you could do:
.. code-block:: python
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``.
.. code-block:: python
from django_filters import rest_framework as filters
class ProductFilter(filters.FilterSet):
class Meta:
model = Product
fields = ('category', 'in_stock')
