title: How to access sphinx_select in search results?
body: <p>I'm using thinking sphinx, with the sphinx_select parameter to create a dynamic field, like so:</p>
  
  <pre><code>@subjects = Subject.search(sphinx_select: "*, petals &lt; 1 or color = 2 as my_attribute")
  </code></pre>
  
  <p>Is there any way to access <code>custom_attribute</code> in the search results? For example:</p>
  
  <pre><code>@subjects.each do |s|
      s.my_attribute
  end
  </code></pre>
  
  <p>Returns</p>
  
  <pre><code>undefined method `my_attribute' for #&lt;Subject:0x007fb25cdcdb18&gt;
  </code></pre>
