django-configurations eases Django project configuration by relying
on the composability of Python classes. It extends the notion of
Django’s module based settings loading with well established
object oriented programming patterns.

Check out the documentation_ for more complete examples.

Quickstart

Install django-configurations:

… code-block:: console

$ python -m pip install django-configurations

or, alternatively, if you want to use URL-based values:

… code-block:: console

$ python -m pip install django-configurations[cache,database,email,search]

Then subclass the included configurations.Configuration class in your
project’s settings.py or any other module you’re using to store the
settings constants, e.g.:

… code-block:: python

# mysite/settings.py

from configurations import Configuration

class Dev(Configuration):
    DEBUG = True

Set the DJANGO_CONFIGURATION environment variable to the name of the class
you just created, e.g. in bash:

… code-block:: console

$ export DJANGO_CONFIGURATION=Dev

and the DJANGO_SETTINGS_MODULE environment variable to the module
import path as usual, e.g. in bash:

… code-block:: console

$ export DJANGO_SETTINGS_MODULE=mysite.settings

Alternatively supply the --configuration option when using Django
management commands along the lines of Django’s default --settings
command line option, e.g.

… code-block:: console

$ python -m manage runserver --settings=mysite.settings --configuration=Dev

To enable Django to use your configuration you now have to modify your
manage.py, wsgi.py or asgi.py script to use django-configurations’s versions
of the appropriate starter functions, e.g. a typical manage.py using
django-configurations would look like this:

… code-block:: python

#!/usr/bin/env python

import os
import sys

if __name__ == "__main__":
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
    os.environ.setdefault('DJANGO_CONFIGURATION', 'Dev')

    from configurations.management import execute_from_command_line

    execute_from_command_line(sys.argv)

Notice in line 10 we don’t use the common tool
django.core.management.execute_from_command_line but instead
configurations.management.execute_from_command_line.

The same applies to your wsgi.py file, e.g.:

… code-block:: python

import os

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
os.environ.setdefault('DJANGO_CONFIGURATION', 'Dev')

from configurations.wsgi import get_wsgi_application

application = get_wsgi_application()

Here we don’t use the default django.core.wsgi.get_wsgi_application
function but instead configurations.wsgi.get_wsgi_application.

Or if you are not serving your app via WSGI but ASGI instead, you need to modify your asgi.py file too.:

… code-block:: python

import os

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
os.environ.setdefault('DJANGO_CONFIGURATION', 'Dev')

from configurations.asgi import get_asgi_application

application = get_asgi_application()

That’s it! You can now use your project with manage.py and your favorite
WSGI/ASGI enabled server.
