Creating GeoDjango model in shell does not work

Description (last modified by Alex)

When you start the shell (python shell) and paste the following code (pasted from

from django.contrib.gis.db import models

class Zipcode(models.Model):
    code = models.CharField(max_length=5)
    poly = models.PolygonField()
    objects = models.GeoManager()

then you receive the following error 'list index out of range'

line 49: kwargs = {"app_label": model_module.__name__.split('.')[-2]}

the model_module refers to: <module '__main__' from '/Library/Python/2.5/site-packages/IPython/FakeModule.pyc'>

This happens with Postgresql 8.4, postgis 1.5.1, OSX 10.5, python 2.5.2

This is not an issue specific to GeoDjango -- same results when the import is from django.db import models and there's no PolygonField or GeoManager. Declaring Django models like this at the shell is not the proper way to define models, as they expect to be a part of an application namespace (hence why it's barfing when trying to figure out the app_label).

If what you really want are dynamic models, then I suggest checking out the existing materials on the subject.
