Django: Как добавить в базу данных с помощью цикла corectly?

Я пытаюсь сохранить в базе данных все бои для данной группы (каждый с каждым) одновременно из формы, взяв количество раундов для каждого из боев, пока что функция ничего не добавляет в базу данных. Я не уверен, можно ли ее добавить в цикле типа такого, следуя списку пар: [(1, 2), (1, 3), (1, 4), (1, 5), (2, 3), (2, 4), (2, 5), (3, 4), (3, 5), (4, 5)] и обращаться к индексам элементов списка при создании объектов боев для сохранения

def add_fights(request, group_id):
    group = Group.objects.get(pk=group_id)
    tournament = group.tournament
    participants = group.participants.all()
    participants_ids = participants.values('id')
    only_ids_ls = [i.get('id', 0) for i in participants_ids]
    participants_pairs = list(itertools.combinations(only_ids_ls, 2))
    group.fighters_one = [p[0] for p in participants_pairs]
    group.fighters_two = [p[1] for p in participants_pairs]
    print(participants_pairs)
    if request.user.is_authenticated:
        form = AddGroupForm(request.POST)
        if request.method == "POST" and form.is_valid():
            rounds = form.cleaned_data['rounds']
            obj = form.save(commit=False)
            if obj:
                for p in participants_pairs:
                    obj.group = group
                    obj.rounds = rounds
                    obj.tournament = tournament
                    obj.fighter_one = group.participants.get(id=p[0])
                    obj.fighter_two =group.participants.get(id=p[1])
                    obj.save()
                    print("obj")
                    print(obj)
                    group.fights.create(group=group, rounds=rounds, tournament=tournament, fighter_one=obj.fighter_one, fighter_two=obj.fighter_two)
                    return HttpResponseRedirect(reverse("tournaments:tournament_details", args=[group_id]))
        else:
            form = AddFightsForm
            return (
                render(request, "add_fights.html", context={
                    'form': form,
                    'group_id': group_id,
