Django IndexError at / list index out of range

I was having problems migrating and when it finally worked this appeared on the home page. Some of the other pages work, and it seems to just be the home page.

Error Messages:

IndexError: list index out of range

I think its on the views.py so here's that code as well.

def racing_stats(request, race_id=None):
drivers = Driver.objects.all().order_by('lap_time')
races = Race.objects.all()
for racer in drivers:
    driver_controller.update_race_time(racer)

if race_id:
    ra = Race.objects.get(rac_id=race_id)
else:
    ra = races[0]

buttons = []
for r in races:
    buttons.append((r.rac_id, r.race_name))
context = {
    'drivers': drivers,
    'active_race': ra,
    'buttons': buttons
}
return render(request, 'racing/racing_stats.html', context)


def race_list(request):
races = Race.objects.all()

context = {
    'races': races,
}

return render(request, 'racing/races.html', context)


def race_detail(request, pk):
    race_ds = get_object_or_404(Race, pk=pk)
    print(race_ds)
    return render(request, 'racing/race_detail.html', 
    {'race_detail': race_ds})
