このコードは、別のオブジェクトの実体/レコードに実際の参照の代わりにnull値を送信し、なぜ私が理解することはできません。これは私の備品を発生させながら、私は私のコンソールで取得メッセージです。symfonyの教義フィクス予期しないNULL値
私はなぜnullという値を代わりに実際の値にするのか知っていますか？ところで、データのループで問題を探すのに時間を費やさないでください。大丈夫だよ。私はこのコードをデータ配列とループなしでテストしましたが、問題は単一エントリで全く同じでした。これは予期しないヌル値です。

あなたは 'getFkCarMark'を呼び出しますが、実際のセッターは決して呼び出しません。したがって、nullのままです。 – Oldskool
