在我安装设计并创建用户模型之后.我rake db:migrate,然后我rake routes.然后我得到一个错误,"未定义的方法`devise_for'为#".可能导致此错误的原因是什么？
我使用rails generate devise user创建了一个模型用户,然后rake db:migrate然后rake路由.一旦我这样做,我知道我的家庭索引中的错误是一个动作控制器异常.他说:
undefined method `devise_for' for #< ActionDispatch::Routing::Mapper:0x105371120>
我的完整痕迹是:

actionpack (3.0.3) …我最近开始创建一个网站,用户可以加入群组并能够与群组互动.到目前为止,我已经为用户使用了设计,但我现在想知道我用什么来创建用户配置文件甚至组配置文件.这是我的第一个rails应用程序,我只需要一些关于从哪里开始的指导？我需要什么工具？这样做的最佳方式是什么？
