Render and Redirect

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.

Render

The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.

// 提高性能
// 让rails server只处理动态请求，不必浪费资源处理静态文件请求
// rails server处理静态文件的性能完全不能和nginx,apache之类的比。

分为三步：

• 同步gems mirror
  安装rubygems-mirror 原来的rubygems-mirror好像有问题，所以使用@huacnlee改过的gem
  按照README.md说明配置.mirrorrc

  # 国内最好用taobao的源,rubygems经常被墙

  - from: http://ruby.taobao.org
  to: /data/rubygems
