应用程序使用Devise gem在Heroku上给出应用程序错误

我正在使用设计gem，我在让我的应用程序在heroku上工作时遇到了问题。 我不确定这是数据库的问题还是设计自己。 在安装设备之前它工作正常。 我在下面放了一个heroku日志。

Answer 1

如本回答所述 ，您需要做的就是在初始化程序目录（ config/initializers/devise.rb ）中创建一个文件，然后将一个密钥放入您选择的密钥中：

 config.secret_key = 'some1234keyq23' 

确保你不只是复制这个密钥，请提出你自己的，如果使用公共项目，不要包含它，因为它应该是一个秘密。
