Django Official Tutorial Part 1 index out of bound error

Question

I started learning Django recently and am having a strange problem with the tutorial. Everything was going fine until I started playing with the interactive shell and then I got an error whenever I tried to call all the objects in one of the tables.

I am using Django 1.1, Python 2.5 on MacOs X.

For those unfamiliar with the tutorial you are making a website to manage Polls. You have the following code in the model:

from django.db import models
import datetime

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
    def __unicode__(self):
        return self.question
    def was_published_today(self):
        return self.pub_date.date() == datetime.date.today()
    was_published_today.short_description = 'Published today?'

class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice = models.CharField(max_length=200)
    votes = models.IntegerField()
    def __unicode__(self):
        return self.choice

After creating the model you add a poll item and then add some choices to it. Everything was fine until I tried to see all the objects in the choices table or tried to see all the choices in a particular poll. Then I got an error. Heres an example series of commands in the interactive shell. Please note that the count of the choices is correct (I have experimented a bit after running into the error so the count is a bit high.)

>>> from mysite.polls.models import Poll, Choice
>>> Poll.objects.all()
[<Poll: What's up>, <Poll: Yups>]
>>> Choice.objects.count()
10
>>> Choice.objects.all()

Thanks!

Answer 1

The problem seemed to be that the database was not synchronized with the models. Resetting the database worked fine. Thanks to Alasdair for the suggestion.
