[issue3315] Importing Django model in an HG hook causes catastrophe

[Nick Jennings]

New submission from Nick Jennings <nick at silverbucket.net>:

See my original post here: http://stackoverflow.com/questions/9620997/using-
a-django-model-from-a-mercurial-python-hook

Basically, when I try to import a Django model in my mercurial hook, I get a 
ton of errors, heres the top of my mercurial hook file:

#!/usr/bin/env python
import sys
path = '/opt'
if path not in sys.path:
    sys.path.append(path)

from django.core.management import setup_environ
from mysite import settings
setup_environ(settings)

from mysite.myapp.models import Build
import datetime



Now, when it executes, I get the following error:
