名前が示すように、分類されたデータベースである「分類済み」と呼ばれるdjangoモデルがあります。分類済みの各インスタンスには、複数の画像が添付されます。そのため、「ClassifiedImage」という名前の別のモデルを作成し、外部キーを介して「分類済み」モデルに関連付けました。Django ジェネリック更新ビューを利用して「分類済み」モデルを更新したいのですが、ジェネリック ビューは 1 つのモデルとフォーム インスタンスしか受け入れません (以下を参照してください *)。しかし、現在、一般的なビューでは、分類されたモデルを更新できるが、その特定のインスタンスの画像を編集できない 1 つのフォーム (この場合は「classifiedForm)」のみを表示できます。外部キー。
