List index out of range on the Django App while running the development server

I just got a new job working for a website and I am trying to get a development server working on my work computer. I've copied all the configurations and what not and I am still getting errors.

When I try to display the front page I get

list index out of range

The exception is being raised

python2.6/site-packages/Django-1.3-py2.6.egg/django/db/models/query.py in __getitem__, line 190

Here is the traceback information.

Exception Type: IndexError at /
Exception Value: list index out of range

Here is some of the code I've got that is adding to the error

class ScheduleManager(models.Manager):
    def get_current_schedule(self, when):
        results = self.filter(start_date__lte=when, end_date__gte=when).order_by('-start_date')
        #try:
        #if(results[0]):
        return results[0]
        #else:
           # return "null"
        #
        #except IndexError:
            #raise self.model.DoesNotExist

    def get_current_schedule_or_404(self, when):
        try:
            return self.get_current_schedule(when)
        except self.model.DoesNotExist:
            raise Http404

I am still not to familiar with python so any suggestions of where to fiddle around with the code would be great. I have a feeling it has something to do with database not being populated with data, but I added in stuff and I still get the error.

Thanks for any help you may give.

If you need more info just let me know.

The traceback tells you what the problem is. The homepage is trying to display the top Schedule - but you don't have any in your database. You need to create some.

Have you tried running it locally in different ways?

I have seen my Django code react differently in different server environs (e.g. mod_wsgi vs gunicorn vs manage.py runserver vs werkzeug... etc). It won't hurt to try a few different codepaths in that respect.

Also, a good sanity check are management commands like manage.py validate and manage.py shell -- I lean on the latter quite a bit when building doctests (which if you're new to python, you'll find out about doctests very soon I would wager).

Best of luck.
