django-configurator 1.1.0

Supports using class based settings for Django and supports various setting object types with validation. This is a port of the original django-configurations project.

django-configurator 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. This is a port of the django-configurations project which is no longer supported. To replace django-configurations with this project, search and replace all occurrences of “configurations” with “dj_configurator” in your project that you were using django-configurations.

Check out the documentation for more complete examples.

Quickstart

Install django-configurator:

$ python -m pip install django-configurator

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

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

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

# mysite/settings.py

from dj_configurator 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:

$ export DJANGO_CONFIGURATION=Dev

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

$ 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.

$ 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-configurator’s versions of the appropriate starter functions, e.g. a typical manage.py using django-configurator would look like this:

#!/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 dj_configurator.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 dj_configurator.management.execute_from_command_line.

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

import os

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

from dj_configurator.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 dj_configurator.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.:

import os

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

from dj_configurator.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.
