Generating XML for a model

rubyonrails-talk

Hi yet again!

I'm currently using an erb template to generate XML for a model (say /persons.xml), because I need custom tags added to the XML I have to generate it from zero.

I tried using person.to_xml but that returns a whole XML document.

Is there an easier way to insert custom values in a model's XML generation? I could redefine the to_xml method but it'd be the same work of having to include all the other values.

Could I define kind of like a virtual column for the model that gets picked up by to_xml?

Thanks!

yes. See the :only, :except and :methods options to to_xml, or the
block form of to_xml
