title: Mongoid Scope order by syntax please
body: <p>I'm using the latest mongoid...</p>
  
  <p>How do I do the mongoid equivalent of this active record named_scope:</p>
  
  <pre><code>class Comment
    include Mongoid::Document
    include Mongoid::Timestamps
  
    embedded_in :post
  
    field :body, :type =&gt; String
  
    named_scope :recent, :limit =&gt; 100, :order =&gt; 'created_at DESC'
  ...
  end
  </code></pre>
