私は、ユーザー、コメント、記事の3つのエンティティを持っています。ユーザーはコメント/記事を作成できます。埋め込みフォームPHP/Symfonyで検証を実行するにはどうすればよいですか？
私の記事コントローラには、コメントフォームを返すと思われるcommentActionというメソッドがあります。私は、このコントローラを記事ショーテンプレートで呼んでいます。それは動作しますが、フォームを検証しようとすると問題が発生します。
ユーザーを記事の表示ページに戻して、コメントフォームのエラーが表示されるようにしたいとします。
2つの問題：フォームには私たちがコメントを取る動作をし、showActionに戻ることはありません。また、何らかの理由で検証エラーが表示されることはありませんでした。
私はフォワーダを組み込んでいました（とにかくうまく動作しないようです）。誰かが私にこれを得る正しい方法を教えてもらえますか？
ありがとうございます！
P.S.私はSymfonで新しくなっていますので、あなたが私に知らせるなら、私がそれを感謝するベストプラクティスに違反しているかどうか私に警告することができます:)。
