Python Django: models in root giving error

Iam newbie to Python and Django. I have following "models.py" file .

from django.db import models
from django.contrib.auth.models import User

class Greeting(models.Model):
  author = models.ForeignKey(User, null=True, blank=True)
  content = models.TextField()
  date = mode开发者_如何学JAVAls.DateTimeField(auto_now_add=True)

1- When I run following command:

from models import Greeting

It gives following error:

IndexError: list index out of range

But when i run above

from guestbook.models import Greeting

it gives no error.

Can some one guide me how can I run "models.py" file (without any error), which exists in root folder(not in "guestbook" application folder)

Thanks in advance

You shouldn't. You are fighting the basic project/application model of Django which underlies the entire system. You will continue to have nothing but problems and issues if you continue down this path.

Create an application and put the models.py in that application's subdirectory.

Edit: I don't mean to sound too harsh but one of the most important things I've learned about Django and Rails is "Don't fight the system".
