RAILS:"会话包含其类定义不可用的对象."

Question

Session contains objects whose class definition isn\'t available.
Remember to require the classes for all objects kept in the session

我正在尝试将http://github.com/binarylogic/authlogic集成 到我的rails应用程序中进行身份验证.我完成了文档中提到的所有步骤.现在,当我点击控制器时,我似乎得到了这个错误.看起来我错过了一些明显的东西.

Answer 1

浏览器cookie？你要告诉所有登录用户吗？:-)

帮助我的是https://gist.github.com/1504625.基本上,更改单个字符config/initializers/secret_token.rb,重新启动服务器并进行设置.

Answer 2

你是如何存储会话的？看起来它正在尝试加载一个旧会话(你在authlogic之前使用的是什么？或者另一个不再存在的类).

删除所有旧会话(如果您在cookie中存储会话,浏览器cookie)可能会解决问题.
