python manage.py syncdb doesn't pull from models.py

I'm not getting a python manage.py syncdb to create tables for my models; this is apparently because an exception is thrown on attempted import of my models and I am somewhat puzzled by the exception:

Importing models as unadorned django.db.models does not help. The models.py is in the same directory as I'm trying to import from; it doesn't seem to behave any differently when I add the current directory to my PYTHONPATH.

What is going on in this error message, and what do I need to do to help it?

The basic structure of the models.py is:

from django.db import models

example_choice = (
    (0, u'first choice'),
    (1, u'second choice'),
    )

[more such choices]

class architecture(models.Model):                                                 
    name = models.TextField(null = True, blank = True)

[more such classes, with more fields and some interconnections but no more sophisticated syntax]

You must have an application package (e.g. myapp) and models must be within it (myapp/models.py) Then you can import myapp.models or from myapp import models.

The error is because django tries to find the appname as the package that contains the models module (the path to the models module must at least have 2 levels of depth).

Besides, the app must be declared within INSTALLED_APPS

Models should be contained within an app, not within the project directly.
