将Rails应用程序部署到Heroku会导致崩溃

时间：2014-07-23 07:20:02

标签： heroku ruby-on-rails-4

这个答案似乎已经以各种方式得到了解答，但没有一个似乎符合我的确切问题。我正在使用RailsApps https://github.com/RailsApps/rails-devise-pundit

中的应用

该应用程序在我当地的Ubuntu 14.04计算机上运行良好，但当我将其部署到Heroku时，我收到了一个“应用程序错误”。在页面上我的应用程序应该已经启动。我跑了＆＃39; heroku日志＆＃39;但无法确定究竟是什么问题。下面是我的日志以及我的Gem文件。任何帮助将不胜感激。谢谢。

这是我的日志

这才是真正导致错误的原因

/app/config/initializers/devise.rb:13

如果您仍然在13中使用此代码

 config.mailer_sender = 'no-reply@' + Rails.application.secrets.domain_name

然后原因是Rails.application.secrets.domain_name是零。在Heroku上你必须通过环境变量设置秘密，并在生产部分的erb parsed secrets.yml中读取它们

e.g
#secrets.yml

 development:  

   domain_name: example.com

production:
   domain_name: <%= ENV['DOMAIN_NAME'] %>
