Is there any documentation for hash\_for\_\*\_url arguments?

What does this function do?

It returns a hash that makes up the pieces of the url necessary for  
url\_for and the one expires\_page that wants a hash.

The arguments are whatever you’d pass to “url\_for”… that is…

\<%=h news\_post\_path(:id =\> 1).inspect %\>  
\<%=h hash\_for\_news\_post\_path(:id =\> 1).inspect %\>

“/news/1”  
{:category=\>“News”, :use\_route=\>:news\_post, :only\_path=\>true,  
:controller=\>“articles”, :action=\>“post”, :id=\>1}
