Using Django models in external python script

Question

I was very confused today.

I was trying to use my django app models in my python script.

here is my approach

import os, sys

sys.path.append("/var/www/cloudloon/horizon")
os.environ["DJANGO_SETTINGS_MODULE"] = "openstack_dashboard.settings"
from django.contrib.auth.models import User

I was confused why its giving me

ImportError: Could not import settings 'openstack_dashboard.settings' (Is it on sys.path?): cannot import name auth

Upon checking I created a a file called creds that includes

export PYTHONPATH=$PYTHONPATH:/var/www/cloudloon/horizon/; 
export DJANGO_SETTINGS_MODULE=openstack_dashboard.settings; django-admin.py shell;

and from terminal window where creds file is located, I do

source creds

and from that django-admin.py shell, I could import any of my django app models without any errors.

Why it doesn't work in my python script?

I am done with Django, What I need to do is to create a python-daemon script that will access my django app models.

I am working with in Ubuntu 12.04 that has django 1.5

As I looking for solutions, I did this:

import os, sys

sys.path.append("/var/www/cloudloon/horizon")
sys.path.append("/var/www/cloudloon/horizon/openstack_dashboard")
# os.environ["DJANGO_SETTINGS_MODULE"] = "settings"
os.environ.setdefault("DJANGO_SETTINGS_MODULE",
                          "openstack_dashboard.settings")

print os.environ["DJANGO_SETTINGS_MODULE"]
for s in sys.path:
    print s

from django.contrib.auth.models import User

heres the output: http://paste.openstack.org/show/48787/

as you can see, the directory where settings.py is located are present on my sys.path, however, It was still unable to import openstack_dashboard.settings.

Thanks everyone.

My solution (inspired by http://blog.gabrielsaldana.org/using-django-models-in-external-python-scripts/):

import os
import sys
sys.path.append( os.path.join(os.path.dirname(__file__), 'MyDjangoProject'))
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "MyDjangoProject.settings")
import django
from django.conf import settings
django.setup()

from myapp.models import MyModel
for s in MyModel.objects.all():
    print(s)
