class User
has_many :comments
end
class Comment
belongs_to :user
named_scope :recent, :order => 'comments.created_at DESC'
named_scope :limit, lambda { |limit| {:limit => limit}}
named_scope :by_unique_users
end
what would I put in the :by_unique_users so that I can do Comment.recent.by_unique_users.limit(3), and only get one comment per user
