xml : why is the Model ID field missing

Sorry if I'm missing something here but I've simply created a respond_to
block with an xml type in it so that user can go to www.foo.com/foos.xml
and get xml back. Works fine but I need the foo_id in there and I don't
see it!

How can I force it's inclusion or can you think of a reason why it might
not be there - all the other fields for the record seem to be there as
far as I can see?


   Can you paste the code? Is there id in generated xml?


You can also override the to_xml method in the model. http://api.rubyonrails.org/classes/ActiveRecord/XmlSerialization.html
