>From the RDoc:
to_xml is controlled with :only, :except, :skip_instruct, :skip_types
and :dasherize. The :only and :except options are the same as for the
attributes method. To not have the column type included in the XML
output, set :skip_types to true.
While that works great when you want to remove some attributes,
sometimes you simply want to add one attribute, creating a builder
template for that seems like an overkill to me.
Can you explain what you mean by using :methods=>[:user_id]?
Would it be bad to add another method to to_xml, such as #add?
One could do:
render :xml => @photo.to_xml( :except
=>[:id, :filename, :updated_at, :height, :width], :add => {:user_id =>
@photo.user.id})
What do you think?
