Dj Database Url

Use Database URLs in your Django Application.


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

The dj_database_url.config method returns a Django database connection dictionary, populated with all the data specified in your URL. There is also a conn_max_age argument to easily enable Django's connection pool.

If you'd rather not use an environment variable, you can pass a URL in directly instead to dj_database_url.parse.

Supported Databases

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


Installation is simple:

$ pip install dj-database-url


Configure your database in from DATABASE_URL:

import dj_database_url

DATABASES['default'] = dj_database_url.config(conn_max_age=600)

Provide a default:

DATABASES['default'] = dj_database_url.config(default='postgres://...')

Parse an arbitrary Database URL:

DATABASES['default'] = dj_database_url.parse('postgres://...', conn_max_age=600)

The conn_max_age attribute is the lifetime of a database connection in seconds and is available in Django 1.6+. If you do not set a value, it will default to 0 which is Django's historical behavior of using a new database connection on each request. Use None for unlimited persistent connections.

URL schema

Engine Django Backend URL
PostgreSQL django.db.backends.postgresql [1] postgres://USER:[email protected]:PORT/NAME [2]
PostGIS django.contrib.gis.db.backends.postgis postgis://USER:[email protected]:PORT/NAME
MSSQL sql_server.pyodbc mssql://USER:[email protected]:PORT/NAME
MySQL django.db.backends.mysql mysql://USER:[email protected]:PORT/NAME
MySQL (GIS) django.contrib.gis.db.backends.mysql mysqlgis://USER:[email protected]:PORT/NAME
SQLite django.db.backends.sqlite3 sqlite:///PATH [3]
SpatiaLite django.contrib.gis.db.backends.spatialite spatialite:///PATH [3]
Oracle oracle://USER:[email protected]:PORT/NAME [4]
Oracle (GIS) oraclegis://USER:[email protected]:PORT/NAME
Redshift django_redshift_backend redshift://USER:[email protected]:PORT/NAME
[1] The django.db.backends.postgresql backend is named django.db.backends.postgresql_psycopg2 in older releases. For backwards compatibility, the old name still works in newer versions. (The new name does not work in older versions).
[2] With PostgreSQL, you can also use unix domain socket paths with percent encoding: postgres://%2Fvar%2Flib%2Fpostgresql/dbname.
[3] (1, 2) 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.
[4] Note that when connecting to Oracle the URL isn't in the form you may know from using other Oracle tools (like SQLPlus) i.e. user and password are separated by : not by /. Also you can omit HOST and PORT and provide a full DSN string or TNS name in NAME part.
