A helper for organizing Django project settings by relying on well established programming patterns.
Project description
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.
Quickstart
Install django-configurations:
pip install django-configurations
Then subclass the included configurations.Settings class in your project’s settings.py or any other module you’re using to store the settings constants, e.g.:
from configurations import Settings
class MySiteSettings(Settings):
DEBUG = True
Set the DJANGO_CONFIGURATION environment variable to the name of the class you just created, e.g. in bash:
export DJANGO_CONFIGURATION=MySettings
and the DJANGO_SETTINGS_MODULE environment variable to the module import path as usual, e.g. in bash:
export DJANGO_SETTINGS_MODULE=mysite.settings
To enable Django to use your configuration you now have to modify your manage.py or wsgi.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:
#!/usr/bin/env python
import os
import sys
if __name__ == "__main__":
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
os.environ.setdefault('DJANGO_', 'MySettings')
from configurations.management import execute_from_command_line
execute_from_command_line(sys.argv)
Notice in line 9 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.:
import os
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
os.environ.setdefault('DJANGO_CONFIGURATION', 'MySettings')
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.
That’s it! You can now use your project with manage.py and your favorite WSGI enabled server.
