Ruby on Rails

Hi,

I'm having trouble with a simple users-messages setup, where users can
send messages to other users. Here's my class definition:

class Message < ActiveRecord::Base
belongs_to :from_user, :class_name => 'User'
belongs_to :to_user, :class_name => 'User'
end

class User < ActiveRecord::Base
def messages(with_user_id)
Message.where("from_user_id = :id AND to_user_id = :with_user_id
OR to_user_id = :id AND from_user_id = :with_user_id",
{ :id => id, :with_user_id => with_user_id })
.includes(:from_user, :to_user)
.order("created_at DESC")
end
end

When I do some_user.messages(another_user.id), I want to retrieve the
conversation that some_user has with another_user. I do get back an
array of Messages, but it doesn't include the eager loading of
from_user and to_user. What am I doing wrong? Am I forced to use
joins?

Thanks,
J
