DatabaseError: no such column

I installed the django-ratings package via pip and followed your installation instructions. I added an anonymous rating field like so:

from djangoratings.fields import AnonymousRatingField

class Foo(models.Model):
    name = models.CharField(max_length=200)
    rating = AnonymousRatingField(range=5)

Then I synced the db:

$ python manage.py syncdb
Creating tables ...
Installing custom SQL ...
Installing indexes ...
Installed 0 object(s) from 0 fixture(s)

However, when trying to open the admin view for my Foo model, I get this error:
