NameError：未定義のローカル変数またはメソッド `config 'for main：Object

Question

Railsが新しく、私のアプリは本番環境でうまく動作しました。しかし、私は最近、Herokuのドメイン名を更新し、今私は以下のエラーが表示されます。私は "config.assets.initialize_on_precompile = false"をいくつかの同様の検索で推奨されているように追加しようとしましたが、これはトリックを行っていません。これを引き起こしていることに関するアイデアはありますか？ここで

Answer 1

：

config.action_mailer.delivery_method = :smtp 
config.action_mailer.smtp_settings = { 
    # ... 
} 

が

Rails.application.configure do 
    # ... 
end 

01の内側に行く必要があります

ブロックのように、configはそこにしか存在しません。
