私はopenweathermap APIからデータにアクセスして情報を取得して情報を表示する簡単なレールアプリケーションを配備しようとしています。ローカルでは検索結果を見ることができましたが、Herokuにデプロイした後、APIからデータを取得しようとするたびにエラーが発生します。ログには、herokuにAPI railsアプリケーションをデプロイ中にエラーが発生しました
と表示されます。ActionView :: Template :: Error（Nil：NilClassの場合、未定義のメソッド[]]： 2017-03-28T23：13：39.240642 + 00：00 app [web.1] ：[9630d05d-78ea-4e76-9c22-17a05ce56b42] 1：[ "名前"]％>ワット<% = @のため
予測、<% = @ [ "SYS"] [ "国"]ワット％>
など。
しかし、私は本当に知りません修正すること
