DJ-Config-URL

Deprecation warning

dj-config-url is no longer maintained. I strongly recommend https://github.com/joke2k/django-environ.

This simple Django utility allows you to utilize 12factor inspired environment variables to configure your Django application.

This project has been forked from kennethreitz' dj-database-url and is fully compatible with it, so you can use this utility as a drop-in replacement.

Supported configuration

Support currently exists for the following database engines: PostgreSQL, PostGIS, MySQL, MySQL (GIS) and SQLite.

You can also configure your CACHES configuration for the backends supported by the Django core: Database, dummy, file based, local memory as well as both Memcached backends.

Installation

Installation is simple:

$ pip install dj-config-url

Usage

Configure your database in settings.py from DATABASE_URL:

DATABASES = {'default': dj_config_url.config()}

Parse an arbitrary Database URL:

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

Configure your cache backend:

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

Use a custom cache backend class:

CACHES = {'default': dj_config_url.parse('memcache://127.0.0.1:123?password=s3cr3t', 'redis_cache.cache.RedisCache')}

Database examples

Engine	Django Backend	URL
PostgreSQL	django.db.backends.postgresql_psycopg2	postgres://USER:PASSWORD@HOST:PORT/NAME
PostGIS	django.contrib.gis.db.backends.postgis	postgis://USER:PASSWORD@HOST:PORT/NAME
MySQL	django.db.backends.mysql	mysql://USER:PASSWORD@HOST:PORT/NAME
MySQL (GIS)	django.contrib.gis.db.backends.mysql	mysqlgis://USER:PASSWORD@HOST:PORT/NAME
SQLite	django.db.backends.sqlite3	sqlite:///PATH [1]

[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.

Cache examples

Backend	Django Backend	URL
Database	django.core.cache.backends.db.DatabaseCache	dbcache://table_name
Dummy	django.core.cache.backends.dummy.DummyCache	dummycache://
File based	django.core.cache.backends.filebased.FileBasedCache	filecache:///path/to/cache
Local Memory	django.core.cache.backends.locmem.LocMemCache	locmemcache://[optional name]
Memcached	django.core.cache.backends.memcached.MemcachedCache	memcache://IP:PORT[,IP:PORT, ...]
PyLibMC	django.core.cache.backends.memcached.PyLibMCCache	pymemcache://IP:PORT[,IP:PORT, ...]

You may specify options for the cache backends as query parameters in the url, e.g.:

CACHES = {
    'default': dj_config_url.parse('filecache:///var/tmp/django_cache?timeout=60&max_entries=1000&cull_frequency=2'),
}

This will be equivalent of writing this in your settings.py:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.filebased.FileBasedCache',
        'LOCATION': '/var/tmp/django_cache',
        'TIMEOUT': 60,
        'OPTIONS': {
            'MAX_ENTRIES': 1000,
            'CULL_FREQUENCY': 2,
        }
    }
}
