Question

我正在尝试在heroku上加载一个应用程序（catarse），但是我有以下问题：应用程序确实部署了，虽然有一些警告，但是当我尝试访问应用程序时，我得到的只是一个空页面。

我做错了什么？

这里是我从heroku日志中得到的：

Answer 1

所有错误都在日志中。

2015-07-21T08：36：36.601314 + 00:00 app [web.1]：E， [2015-07-21T08：36：36.601197＃7]错误 - ：应用程序错误：丢失设置为{生产'环境的secret_token和secret_key_base 这些值在config/secrets.yml（RuntimeError）
中

您应该在config / secrets.yml文件中添加以下行：

production: secret_key_base: <%= ENV["SECRET_KEY_BASE"] %> （小心缩进）

另外，请确保在您的环境变量中（在您的应用程序的heroku仪表板上可见 - > gt;设置 - ＆gt;显示配置变量），变量SECRET_KEY_BASE存在。

你应该在这里找到一些关于如何使用Heroku管理秘密令牌的好信息：http://daniel.fone.net.nz/blog/2013/05/20/a-better-way-to-manage-the-rails-secret-token/

应用程序在heroku上部署，但只生成空白页面
