Article urls in @articles.to_xml

Rails
1

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:

    firm.to_xml :methods => [ :calculated_earnings, :real_earnings ]

    … normal attributes

    passed a modified version of the options hash that was given to to_xml.

    proc = Proc.new { |options| options[:builder].tag!(‘abc’, ‘def’) }
    firm.to_xml :procs => [ proc ]

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 :frowning:
