Not able to modify DataBase with django

Question

I am new to django. Want to create tables in the Database of my project, so I searched the tutorial. models.py:

from django.db import models

class Blah(models.Model):
    first = models.IntegerField()
    second = models.IntegerField()

Script to write data into db:

from django.conf import settings

settings.configure()
from core.models import Blah
b = Blah(first = 1, second = 2) 
b.save()

When I am trying to launch the script with django 1.9, it gives me the error:

C:\Python27\Scripts\reports>to_db.py
Traceback (most recent call last):
  File "C:\Python27\Scripts\reports\to_db.py", line 4, in <module>
    from core.models import Blah
  File "C:\Python27\Scripts\reports\core\models.py", line 5, in <module>
    class Blah(models.Model):
  File "C:\Python27\lib\site-packages\django\db\models\base.py", line 94, in __new__
    app_config = apps.get_containing_app_config(module)
  File "C:\Python27\lib\site-packages\django\apps\registry.py", line 239, in get_containing_app_config
    self.check_apps_ready()
  File "C:\Python27\lib\site-packages\django\apps\registry.py", line 124, in check_apps_ready
    raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

I have already added the app to INSTALLED_APPS and I am able to do the exact same commands with "manage.py shell", but not with the script.

What am I missing here?

Thanks

If you do need to script against Django (and the ORM), you'll want to use the shell admin command , passing your script as input to it. Related question
