scaffolding通过提供列出、显示、创建、更新和销毁类的对象的标准化动作，快速地使一个Activerecord类上线。
Scaffolding quickly put an Active Record class online by providing standardized actions for listing, showing, creating, updating, and destroying objects of the class.
如果你添加了一个进程扩展到工具菜单或者一个对象的动作菜单，他们会按照你创建时候的次序列在标准菜单之后出现。
If you add process extensions to either the Tools menu or an object's Action menu, they are listed after standard menu commands in the order they were created.
创建该视图需要的唯一信息是角色名，我用标准的input元素进行采集，并将该值递交给Create动作方法。
The only information required to create a new view is a name, which I gather using a standard input element and submit the value to the create action method.
