THx for the help! I've solved it in the following way:
1) Appended to User model
has_one :most_recent_status, :class_name => 'Status', :order =>
"created_at desc"
2) In users_controller wrote:
def index
hobo_index do |wants|
wants.xml {
render :xml => @users.to_xml ( :include =>
[:most_recent_status, :messages ])
}
wants.html { }
end
end
