Learning what DJANGO_SETTINGS_MODULE is for

I wonder which is what of the followin开发者_StackOverflowg:

os.environ['DJANGO_SETTINGS_MODULE'] = 'conf.settings'

os.environ[u'DJANGO_SETTINGS_MODULE'] = u'conf'

can you explain?

This defines the settings file name in case of production use.

In case of deployment you can use a separate settings file let us say *production_settings.py* which imports from the main settings file settings.py. You could define some separate settings for deployment like SITE_ID, DEBUG etc.

So in your deployment .wsgi file DJANGO_SETTINGS_MODULE environment variable can be defined to use the separate settings file.

os.environ['DJANGO_SETTINGS_MODULE'] = 'conf.production_settings'
