内容

config.action_mailer.delivery_method = :smtp 
config.action_mailer.smtp_settings = { 
    :address    => "localhost", 
    :port     => 25, 
    :domain    => 'mydomain.com', 
    :openssl_verify_mode => 'none', 
    :tls     => false, 
    :enable_starttls_auto => false 

}

谁能告诉我如何去解决此问题？当我对任何文件进行更改时，是否需要重新启动passenger或nginx或我的rails应用程序？错误消息太隐秘，无法知道在哪里寻找问题。谢谢你的帮助！ :)

答

您正试图访问您的应用程序的配置对象超出正确的上下文。尝试包装你这样的代码：

AppName::Application.configure do 
    config.action_mailer.delivery_method = :smtp 
    # etc ... 
end

或用AppName::Application.config替换每个config。
