Try to add here:

has_one :list_with_celebs, :class_name => "List", :include => :celebs


end

class List < ActiveRecord::Base
belongs_to :user
has_many :celebs
end

class Celeb < ActiveRecord::Base
belongs_to :list
end

I want to load a user's list, and include the celebs that belong to it. I tried the following:

@user = current_user

... @list = user.list.joins(:celebs)
... @list = user.list(:include => :celebs)
... @list = user.list.includes(:celebs)

@user.list_with_celebs

HTH,

Peter
