私は3つの主要なモデルを持っています。質問表モデルまたは質問セットには、一連の質問が含まれています。すべてのユーザー応答は answer に保存されます。
ここで、すべての質問の回答をアンケート セットに保存するフォームセットを生成する必要があります。どうすればdjangoでそれを行うことができますか. これまでのところ、特定のアンケートから一度に 1 つの質問を表示し、回答を保存することでそれを行うことができました。私の問題は、質問タイプに基づいて2つの異なるモデルフォーム（MultipleChoiceAnswerForm、DescriptiveChoiceAnswerForm）を使用し、フォームタイプに基づいてそれらを検証することです。フォームセットでどのように使用できますか。
私はジャンゴの初心者で、どんな助けも大歓迎です。
私のコード:
