The model definition must come in an application - the error you're seeing there is that it tries to take the __name__ model_module - which should be something like project.appname.models for project\appname\models.py - and get the app name, appname. In the interactive console, the module's __name__ is '__main__' - so it fails.

To get around this, you'll need to specify the app_label yourself in the Meta class;

>>> from django.db import models
>>> class Poll(models.Model):
...     question = models.CharField(max_length=200)
...     pub_date = models.DateTimeField('date published')
...     class Meta:
...         app_label = 'test'

For explanation of why you can do that, look at that file mentioned in the traceback, D:\Python25\lib\site-packages\django\db\models\base.py:

    if getattr(meta, 'app_label', None) is None:
       # Figure out the app_label by looking one level up.
       # For 'django.contrib.sites.models', this would be 'sites'.
       model_module = sys.modules[new_class.__module__]
       kwargs = {"app_label": model_module.__name__.split('.')[-2]}
   else:
       kwargs = {}

(Where meta is the Meta class, see just above in that file.)
