This simple Django utility allows you to utilize the 12factor <http://www.12factor.net/backing-services>_ inspired CACHE_URL environment variable to configure your Django application.

This was built with inspiration from rdegges' django-heroku-memcacheify <https://github.com/rdegges/django-heroku-memcacheify>_ as a way to use CACHE_URL in apps that aren't necessarily hosted on Heroku.

The internals borrow heavily from kennethreitz's dj-database-url <https://github.com/kennethreitz/dj-database-url>_.

Usage

Configure your cache in settings.py from CACHE_URL::

import django_cache_url
CACHES = {'default': django_cache_url.config()}

Defaults to local memory cache if CACHE_URL isn't set.

Parse an arbitrary Cache URL::

CACHES = {'default': django_cache_url.parse('memcache://...')}

Supported Caches

Support currently exists for:

All cache urls support optional cache arguments by using a query string, e.g.: 'memcached://HOST:PORT?key_prefix=site1'. See the Django cache arguments documentation_.

.. [#memcache] To specify multiple instances, separate the the HOST:PORT``` pair by commas, e.g:'memcached://HOST1:PORT1,HOST2:PORT2``
