関連するすべてのレコードを一度に保存

Question

関連するレコードをcakephp3に保存することはできますが、コードを見ると1回の保存呼び出しですべてのレコードが一度に保存されることはありません。 すべてのレコードを一度に保存しようとすると問題が発生しました。 GuardianとUsersテーブルがどのように処理されているかを見ると、個別に保存されます。 コードは動作し、レコードを保存しますが、ガーディアンテーブルでエラーが発生したため、1回の保存呼び出しですべてを一度に保存することは問題でした。

Guardians have a 1 to many relationship with students 
Students and Users have a 1 to 1 
Students to subjects and availabilityFotStudents both have a many to many

あなたはTranactionalデータを保存することができます。複数の保存方法を実行できる場所。保存メソッドが失敗した場合、保存されるデータはありません。それはあなたが言及した "1セーブコール"のように機能します
