Localhost：3000申し訳ありませんが、何かが間違っていました

Question

私はHerokuに私のレールのウェブサイトを配備して、うまくいきました。それでは、問題はlocalhost：3000で自分のウェブサイトを開くことができないことです。それは私が何をするか分からないと恐怖は、最悪のそれを作るだろう、コンソールログをレールこれは私が$からもらったログです

We're sorry, but something went wrong. 

If you are the application owner check the logs for more information. 

を示しました。どんな助けもありがとう！

config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly: 

    * development - set it to false 
    * test - set it to false (unless you use a tool that preloads your test environment) 
    * production - set it to true

問題は、データベースを構成していないことです。

データベースが構成されていません。利用可能：["default"、 "development"、 "test"、 "production"]（ActiveRecord :: AdapterNotSpecified）

database.ymlファイルで設定してください。 Cofiguring a database - Rails guides
