title: Trying to return AREL not Array in Rails
body: <p>I have two models: Products and Tags through a products_tags join in a HABTM relationship.</p>
  
  <p>I am currently defining my controller index as:</p>
  
  <pre><code>@stats = Product.all(:include =&gt; :tags).uniq
  </code></pre>
  
  <p>which returns an array. How can I return an Active Rel object? I tried added scoped, however received a no method error. </p>
  
  <p>I need to find and list a unique list of tags, and be able to view what product each specif tag belongs to. </p>
