Ruby on Rails

Hi guys

I am not sure if it is actually possible what I am trying to do, but
Im sure you can help me with it.
Let me start with my models:

class User < ActiveRecord::Base
has_many :wall_posts, :class_name => "Post", :foreign_key =>
"wall_id", :order => 'created_at DESC'
has_many :invites, :class_name => "Invite", :foreign_key =>
"contact_id", :order => 'created_at DESC'
end

Now what I want is to combine this to a sort of stream (facebook
style). This works fine if I do it with an array as in:

def stream
stream = wall_posts + invites
end

but in my view I am using a little bit of javascript and ajax to make
an 'endless' page. So of course I am using limit and offset. This
works fine on SQL queries but not for the arrays. So obviously it is
then not possible to write user.stream.limit(6).offset(6) because its
already an array..

i tried different joins on posts but i cant really get it to work
properly. I have to mix them into a stream so that they arrange
properly chronologically.

Thank you for your help, I appreciate it.

Kind regards
Stefano
