RoR 4没有正确推送到heroku

Question

编码有点新，只是把我的网站推到了heroku。我以前做过没有任何问题，但现在它给了我“我们很抱歉，但出了点问题。”每当我尝试去现场时。 我运行了heroku logs --tail，这就是它给我的东西。

稍后我会看到这个

我从未见过这个错误，我很困惑。让我知道我应该在这里发布什么。这是我的git中心页面https://github.com/Thefoodie/PupPics

Answer 1

错误

ActionView::MissingTemplate (Missing template pages/opening, application/opening with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :build er, :raw, :ruby, :jbuilder, :coffee]}. Searched in:

这是标准view is missing错误 - 基本上意味着/views/pages/opening.html.erb文件尚未上传：

1. 确保您有/views/pages/opening.html.erb
的文件

2. 确保您已添加＆amp;将文件提交给git：

   • git add .
   • git commit -a -m "Opening"
   • git push heroku master

Exception Notification

你可以使用名为exception notification的优秀宝石：

  

Exception Notification gem提供了一组发送通知程序   Rack / Rails应用程序中发生错误时的通知

如果您这样安装，您将能够直接收到错误消息到您的电子邮件收件箱。以下是您设置的方式：

#GemFile
gem "exception_notification", "~> 4.0.1"

#config/environments/production.rb
Whatever::Application.config.middleware.use ExceptionNotification::Rack,
  :email => {
    :email_prefix => "[Whatever] ",
    :sender_address => %{"notifier" <notifier@your_domain.com>},
    :exception_recipients => %w{you@domain.com}
}

然后，您需要收到电子邮件，最好使用第三方SMTP平台，例如SendGrid或Mandrill：

#config/environments/production.rb
ActionMailer::Base.smtp_settings = {
  :address        => "smtp.sendgrid.net",
  :port           => "25",
  :authentication => :plain,
  :user_name      => ENV['SENDGRID_USERNAME'],
  :password       => ENV['SENDGRID_PASSWORD'],
  :domain         => ENV['SENDGRID_DOMAIN']
}
