I make a mini poll system. To each question choices are related via
FK. In admin I use Inline choices. Each choice has "correct" field
(Boolean). When saving a poll I need to check if there is minimum 1
choice with "correct" selected. Which function in admin I must use, to
do that validation?

Try something like that:
poll = get_object_or_404(Poll, pk=poll_id)
try:
selected_choice = poll.choice_set.get(pk=request.POST['choice'])
correct = selected_choice.correct
if correct:
do something
except (KeyError, Choice.DoesNotExist):
return render_to_response('youtemplate', {
'poll': poll,
'error_message': "Please select a choice",
})
