Hello there,

I have an empty Asset model which only contains 3 attr\_accessor  
attributes (:uploaded\_data, :title, :description), which I can fill  
just fine using form\_for etc, but when trying to do it restfully, the /  
assets/new.xml just returns an empty

\<?xml version="1.0" encoding="UTF-8"?\>

Is there a way to serialize / @asset.to\_xml including the  
uploaded\_data/title/description attributes?

format.xml { render :xml =\> @asset.to\_xml(:only =\>  
[:uploaded\_data, :title, :description]) } returns the same as  
above… :-/

Thanks,  
-Jörg
