Here's an example of:
In your Photo class you can define a method 'user_id':
class Photo
def user_id
user.id
end
end
Then get to_xml to include it when serializing with a :methods =>
[:user_id] option.
My opinion is that the :methods way should work for you quite well
(there's no need for the proposed :add option). Otherwise, Builder
templates is the way to go if you're going after something more
complicated.
