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

Supported databases
-------------------

Support currently exists for PostgreSQL, PostGIS, MySQL, MySQL (GIS) and SQLite.

Installation
------------

Installation is simple::

    $ pip install dj-database-url

Usage
-----

Configure your database in ``settings.py`` from ``DATABASE_URL``
(``default`` is optional)::

    DATABASES = {'default': dj_database_url.config(default='postgres://...')}

Parse an arbitrary Database URL::

    DATABASES = {'default': dj_database_url.parse('postgres://...')}

.. [1] SQLite connects to file based databases. The same URL format is used, omitting
       the hostname, and using the "file" portion as the filename of the database.
       This has the effect of four slashes being present for an absolute file path:
       ``sqlite:////full/path/to/your/database/file.sqlite``.
