Versioning and stability policy
-------------------------------

Django-Filter is a mature and stable package. It uses a two-part CalVer
versioning scheme, such as ``21.1``. 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 versions <https://devguide.python.org/versions/#supported-versions>`_
* `List of supported Django versions <https://www.djangoproject.com/download/#supported-versions>`_

Support for Python and Django versions will be dropped when they reach
end-of-life. Support for Python versions will be 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')
