laravelログファイル（Laravel 5.4）からエラーのあるルートを見つける方法

Question

laravel.logファイルのおかげで、問題のあるソースコード行と変数を見つけることができます。

しかし、時には完全なルートが必要です。特定のルートインスタンスでエラーが発生するため、エラーを生成できません。

サンプルエラーログは以下のとおりです。しかし、ルートインスタンスについては何も言わない。どうすれば入手できますか？

Answer 1

あなたが見ているエラーが（見つからない）ビュー内の変数posts_recommendsの使用に関連しています。

my_site/storage/framework/views/ef89cba27180cabe.php（キャッシュされたバージョンのビュー）を調べて、影響を受けるビューを確認することができます。これにより、修正する必要のある実際のビューファイルがわかります。

レンダリングしようとしているビューに関連しているので、このエラーを修正する正確なルートを知る必要はありません。
