dj-config-url 0.1.0

Use configuration URLs in your Django Application.

Latest Version: 0.1.1

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,
        }
    }
}
