I have a script that imports a models.py from an app, but it will not import! I don't believe I am supposed to manually create an "export DJANGO..." environment variable...I'm doing something else wrong.
Traceback (most recent call last): File "parse.py", line 8, in ? from butterfly.flower.models import Channel, Item File "/home/user/shri/butterfly/flower/models.py", line 1, in ? from django.db import models File "/usr/lib/python2.4/site-packages/django/db/__init__.py", line 10, in ? if not settings.DATABASE_ENGINE: File "/usr/lib/python2.4/site-packages/django/utils/functional.py", line 269, in __getattr__ self._setup() File "/usr/lib/python2.4/site-packages/django/conf/__init__.py", line 38, in _setup raise ImportError("Settings cannot be imported, because environment variable %s is undefined." % ENVIRONMENT_VARIABLE) ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.

Manually or otherwise, you are supposed to ensure that variable is in the environment before you import a Django models file -- not sure what the causes are for your disbelief, but, whatever they may be, that disbelief is ill-founded.
You need to properly import your settings file. If you don't import the django environment variables first, your import will fail as you've noticed. You need to code something like:
import os # Set the DJANGO_SETTINGS_MODULE environment variable. os.environ['DJANGO_SETTINGS_MODULE'] = "myproject.settings" #do your stuff
