私はlaravel 5.2バージョンとPHP 7.1を使用しています。以下に示すように、列の存在を確認するコードがあるlaravelプロジェクトからファイルを移行しようとしています-
if (!Schema::hasColumn('table1', 'column1')) {
// Add column1
}
私はコードが完全に問題ないことを知っており、これは同じコードをセットアップしている間にすでに数回機能しています。しかし、今私は別のマシンでこれを試していますが、エラーで失敗します -
[ErrorException]
未定義のプロパティ: stdClass::$column_name
コードから hasColumn チェックを削除すると、このエラーを取り除くことができますが、これはコード全体に記述したものであり、移行を実行するためだけにすべての移行を変更することはできません。
これに関するヘルプは大歓迎です。
スタックトレース：
