服务器崩溃，我重新启动，现在Devise坏了？

我在一个封闭的博客和讨论网络应用程序上工作，一切都很好;设计，康康，登录，一切正常。当我为实现跟随其他用户的用户/关系模型进行调整时，服务器崩溃了。这是运行服务器的控制台出现的问题。希望它并没有表明我是一个多么糟糕的编码器。我不知道这个粘贴有多少是相关的，但实际的崩溃是在最底层。

Abort trap

所以我喜欢＆＃34;嗯，这很奇怪，＆＃34;并重新启动服务器，但现在一切都坏了。行为人似乎是Devise。如果不是'current_user不是未定义的本地变量或方法，那么我的导航栏（bootstrap ftw）中的Devise实现也会被破坏。不管错误是什么，我网站上的每一页都被破坏了，而且这一切似乎都与设计有关。

我正在做这个项目以熟悉Rails，我非常喜欢它，但我还是新手，我不知道wtf刚刚发生过。救命？我可以粘贴你们可能要求的任何其他代码。

如果您的开发机器尝试重新创建数据库

rake db:drop
rake db:create

答案 1 :(得分：0)

你可能有一个损坏的宝石。尝试

bundle exec gem uninstall <devise gem name>

无论你使用什么版本的Devise。然后再次运行bundle install。这应该卸载并重新安装Devise gem。

如果这不起作用，您可以尝试将存储库克隆到新目录的强力方法。
