我在设置新的rails项目时遇到问题。它在开发模式下工作正常但在生产中崩溃。这就是我的意思。
我只有一个带有rails的单一方法的控制器
rails g controller Products list
到目前为止一切顺利。当我输入http://localhost:3000/products/list时，我从视图中获取默认消息。
当我将RAILS_ENV更改为生产时重新启动服务器并重新加载页面时出现错误We're sorry, but something went wrong.
以下是production.log的内容

看起来您的config/secrets.yml没有生产环境的条目（或条目配置错误）。
production:
secret_key_base: 527dacc0390e10df59278f1a18aa8ad14e429fa6ce522e5fb3b7ac358007dff4
请勿使用此处发布的密钥。您可以使用rake任务生成一个新任务并将其粘贴到config/secrets.yml文件
bundle exec rake secrets
