Here is the whole list what I did. I think it works for you because I am working on 1.4.2 and document is created for 1.4.
The Issue tracker does not have option to select 1.4.2 in version list.
django.get_version()
'1.4.2'

I think you have a mistake in your polls/models.py file. Does it look like the tutorial instructs?
from django.db import models class Poll(models.Model): question = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') class Choice(models.Model): poll = models.ForeignKey(Poll) choice = models.CharField(max_length=200) votes = models.IntegerField()
Please use the support channels in the link above if you have problems.

Here is my rerun of the interactive shell commands and model is enclosed. Since I have proceeded to tutorial 3 but it is not different from your model. See enclosed file (model.py: https://code.djangoproject.com/attachment/ticket/19311/models.py) for the model reference.

Your Choice model uses question
rather than poll
as a foreign key to Poll.
I think you must have made a mistake somewhere.
