Everything is great, but what about --settings=?

When you use the --settings option, all that Django does is to set the DJANGO_SETTINGS_MODULE environment variable for you (https://github.com/django/django/blob/master/django/core/management/base.py#L42-43)

So this:

./manage.py import_content --settings=project.build_settings

is identical to:

DJANGO_SETTINGS_MODULE=project.build_settings ./manage.py import_content

In other words you can still use that ability to switch between modules. If you use a settings class with the same DJANGO_CONFIGURATION name in each of your settings modules, you should be fine.

That said, I admit this is less than optimal, as you ideally should also be able to set the DJANGO_CONFIGURATION environment variable like the DJANGO_SETTINGS_MODULE variable as a command line option, e.g.:

./manage.py import_content --settings=project.build_settings --configuration=Prod

I'm not completely sure if that use case is the one you're looking for, being able to switch between different settings classes in one module (project/build_settings.py). In my opinion though that should be the goal: having a central settings file that may or may not import setting classes from other modules (for easier code organization) that stores different settings classes (depennding on environments such as Prod, Dev, Test etc) that you can switch between by simply setting the DJANGO_CONFIGURATION environment variable. That's at least how I use it.

I'd be open to adding the ability to also have an optional --configuration command line option for all management commands to set that environment variable like --settings sets DJANGO_SETTINGS_MODULE. What do you think?

Thanks. With django-configurations, I plan to have only one settings file. i.e. I won't need to have projects/build_settings.py, projects/celery_settings.py, etc. anymore. Everything can go inside projects/settings.py as Build, Celery, etc.

So for me, --configuration=Build would suit me just fine.

Thanks!
