django - Django カスタムフォームセットを保存する方法

Question

次のカスタム フォームセットを作成しましたが、私の人生では、フォームを保存する方法がわかりません。私は Django ドキュメントを検索し、広範な検索を行いましたが、解決策は 1 つもありません。うさぎの穴がたくさんありますが、肉はありません;-) 誰かが私を正しい方向に向けることができますか?

        if formset.is_valid():

            formset.save()

            return HttpResponseRedirect(reverse('games_game_list'))

        else:

            formset = TeamStatFormSet(group_slug=group_slug, team_id=team_id, game_id=game_id)

        return render_to_response(template_name, {'formset': formset,})
