Herokuがdevise、rolify、punditを使ってRailsアプリケーションを正しくデプロイすることができません。

Question

自分のビュー/コントローラで非常に基本的な使い方とともに、私が追加した空白のRailsアプリケーションを作成しています。私の開発環境（Cloud 9）ではうまくいきます。

しかし、私がHerokuにデプロイすると、すべてがうまくいったと書かれていますが、一般的な「残念ですが、何かが間違っていました。

だから私は行って、チェックしたログを、私は、これは重要なラインであることを賭けることをいとわないだろう：

2016-04-05T22:58:08.451507+00:00 app[web.1]: ActionView::Template::Error (undefined method `has_role?' for nil:NilClass): 

この私には私には新しい宝石が正しくインストールされていないことを示しています。ここで

heroku run bundle update 
heroku run bundle install 
heroku run rake db:migrate 
heroku run rails generate devise:install 
heroku run rails generate pundit:install 

は役立ちます場合は、完全なログです：私は明らかにHerokuのコマンドを試してみました。

何がいいですか？

Answer 1

current_userはゼロです。あなたがログインしていることを確認し、その電話をかける前にcurrent_userの存在を確認してください。
