Hi, A call to to_xml(:only => [:field], :include => :association]) will filter the association result too(the resulting association will only have :field). Is there a way around this? I want to specify different filters for the main object and the association. -- M.

Marcelo Unfortunately like you mentioned when you use the :only options it will filter through all the associations as well. You can get around this by passing a proc to_xml that appends the associations to the builder. For example we will take the ever so popular example of a User having many Posts. class User has_many :posts end class Post belongs_to :user end user = User.first posts = user.posts post_proc = lambda do |options| options[:builder] << posts.to_xml(:skip_instruct => true) end user.to_xml(:only => :first_name, :procs => post_proc) Make sure you have the :skip_instruct => true option when you are creating the xml for your associations so it does not add the XML declaration <?xml version="1.0 ... > Cheers. -- Robert Z.
