I am reading RESTful Web Services, where it is advised as a good  
practice to connect resources.

Is there a way to include article urls in @articles.to\_xml ?

Thank you!

I wondered though whether there was a builtin way in AR::Base#to\_xml  
to generate something like this:

`AGH877` 234.45 ...

AFAIK you have to code that customization yourself. (Of course a model  
does not know it has a URL so that’s fine.)

As far as I know, simple ways to do it are (from the Rdoc  
documentation):

- Including any methods on the object(s) being called, using :methods:

- Calling any Proc‘s on the object(s), uinge :procs. The Proc‘s are  
passed a modified version of the options hash that was given to to\_xml.

standard rails restful stuff uses a predictable URL scheme, so this  
isn’t really needed. Also, routing uses the current request context,  
and that’d have to be passed into #to\_xml somehow. You could do that  
now using the :procs option.

Ah, yes, I have right now this same problem. I’m afraid the only way to  
do it is creating your own RXML template ☹
