Using DjangoModels without a server running

Dear all,
I need to import some xml into my webapp (called ltb1) – it’s a one-off thing so I want to do it outside
the webapp, but still making use of all the models I’ve defined in it..
So I created a new package in my djangostack/projects/ltb1 which contains a new module ‘import_xml’.
I should be able to access the DB through the django models, so to parse the xml and feed the results
into the DB accordingly.
(Essentially, I wanted to manually load whatever usually gets loaded with ‘manage.py’):

import sys, os,  ltb1.settings
from django.core.management import setup_environ
setup_environ(ltb1.settings)

from ltb1.ltbapp.models import MyModel

It seems to work till the ‘setup_env….’ but then it fails when I try to import my models. Here’s the result:

Traceback (most recent call last):
