Django: AppRegistryNotReady()

by

If you are using your django project applications in standalone scripts, in other words, without using manage.py – you need to manually call django.setup() first – it would configure the logging and, what is important – populate apps registry.

Quote from Initialization process docs:

setup()

This function is called automatically:

  • When running an HTTP server via Django’s WSGI support.

  • When invoking a
    management command.

It must be called explicitly in other cases, for
instance in plain Python scripts.

In your case, you need to call setup() manually:

if __name__ == '__main__':
    print "Starting Rango population script..."
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tangle.settings')

    import django
    django.setup()

    populate()

Also, this problem is described in detail in Troubleshooting section.
