我如何走铁路资源的绝对道路?
原标题:How do I get the absolute path of a resource in Rails 3?

我希望获得资源的全部绝对道路,包括铁路3域名。

实例:我尝试过一条通向主页的道路:

url_for( :controller =>  home , :action =>  index  )

以及

root_path

但两者都只给我:/,但我希望: http://www.example.com/

The answer should also work on my dev server 以及 return: http://localhost:3000/

最佳回答

使用<代码>root_url。 <代码>_url 最终展期时,全文见URL,例如http:// localhost:3000/projects/1/topets/2

问题回答

瑞安的答复完全正确。

但是,如果你真的需要使用<代码>url_for 某天,仅添加<代码>:只添加_path =>不实,以备选择,并因此而使你具有绝对性;]

If you want the resouce url (instead of only the root url). You have to use resoure_name_url(@resource_instance)

例:

resource_url(@resource_instance)

或者如果您有(例如)用户资源:

user_url(@user)
