Ruby On Rails各版本需注意

1.4ruby script/server -p port  使用指定的端口启动ruby on rails网站服务

2.为"/"创建路由需要在默认路由下,如在rails2.3中

 

?

1 2 3

map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format' map.root :controller => "home"

否则将报错如:

Routing Error

No route matches "/product" with {:method=>:get}
