Hartl の RoR チュートリアルの第 7 章を完了しました。すべての Spec テストに合格し、アプリは localhost で期待どおりに実行されます。しかし、アプリは Heroku でクラッシュしました。ログは意味がありません。Heroku の警告メッセージで示唆されているように、Ruby のバージョンを明示的に 1.9.3 に設定しましたが、違いはありませんでした。Heroku で実行する
Ruby -v は 1.9.3 を提供し、ログは 1.9.1 を示唆しています
これがログを投稿する正しい方法かどうかはわかりませんが、以下は Heroku ログのダンプです。

言うまでもなく、完全な初心者であるため、ログはほとんど意味がありませんが、第 7 章まではすべて正常に機能していました。したがって、どこかで私の学生のエラーに違いありませんが、エラーと Google 検索をデバッグする方法がわかりません。 「堅い」ものは何も与えないでください。
アドバイスをいただければ幸いです。

以下は、私のリポジトリへのリンクと User クラスの詳細を提供します。

以下は私の User クラスです。私はこれを見ましたが、明らかに間違っているものは何も見られませんでした:
class User < ActiveRecord::Base
attr_accessible :name, :email, :password, :password_confirmation
has_secure_password
before_save { |user| user.email = user.email.downcase }
validates :name, presence: true, length: { maximum: 50 }
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :email, presence: true, format: {with: VALID_EMAIL_REGEX },
uniqueness: { case_sensitive: false }
validates :password, presence: true, length: { minimum: 6 }
validates :password_confirmation, presence: true
after_validation { self.errors.messages.delete(:password_digest) }
end
