Question

私は新しいですStackoverflow &レール、こんにちは！

私は周りを見てきたし、一緒にすべてを得ることはできません。

私は4つの異なるフィールドを持つ新しいクライアントを追加できるダッシュボードを作成しています。次に、ユーザーが8つの異なるフィールドを持つプロジェクトを特定のクライアントに追加できるようにします。しかし、私はクライアントにプロジェクトを追加し、それを表示するのに苦労しています。コードを公開しました：https://github.com/JackStovell/revenue-dashboard。

&にコードをリッピングしてください。どこに間違っているのか教えてください。調整することができます！ここで

おかげ
