When should you use django-admin.py versus manage.py?

Background:

When I run the django-admin.py loaddata example.json I get this error. "ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined." I understand the problem. It needs the DJANGO_SETTINGS_MODULE to be able to access the database to do this import. I've had this problem before and I've managed to side step it thus far.

In reading the docs, I discovered that the manage.py is a wrapper for django-admin.py; it puts the project on the sys.path and sets the DJANGO_SETTINGS_MODULE environment. Woot! Whoa! I know how to fix my problem.

Soo... Why do the Django documentation code examples use django-admin.py instead of manage.py when demonstrating subcommands such as loaddata and dumpdata?

If your DJANGO_SETTINGS_MODULE environment variable is set, you can use django-admin.py from any working directory, whereas you need to be in the project directory to use ./manage.py (or have it in your path).

Use virtualenv, and have DJANGO_SETTINGS_MODULE set by bin/activate, and then you can use django-admin.py.

Well, because these scripts are the same in priciple, with the differences, you already mentioned. The Django docs also mention

django-admin.py <subcommand> [options]
manage.py <subcommand> [options]

side by side. Usually you use django-admin.py to start a new project or application and manage.py to do the rest.
