我是Ruby的新手,并且一直关注着"Ruby On Rails 3 Tutorial - Learn Ruby by Example - Michael Hartl"一书.我目前在第3章讨论静态页面.
在本章中,我在提示符中输入了以下命令:rails generate controller Pages home contact一切正常.
然后这本书指引我http://localhost:3000/pages/home.当我将浏览器指向那里时,我收到以下错误.
ActiveRecord::ConnectionNotEstablished ActiveRecord::ConnectionNotEstablished Rails.root: /home/ralph/railsprojects/sample_app Application Trace | Framework Trace | Full Trace
路由和控制器erb似乎没有任何错误.这是数据库相关的错误吗？有任何想法吗？
谢谢,DMAT
