title: Dynamically Adding Columns to a DBIx::Class ResultSet
body: <p>I have a <code>DBIx::Class</code> object representing an eBay auction. The underlying table has a description column which contains a lot of data. The description column is almost never used, so it's not included in the <code>DBIx::Class</code> column list for that table.  That way, most queries don't fetch the auction description data.</p>
  
  <p>I do, however, have one script that needs this column.  In this one case, I want to access the contents of the description column as I would any other column:</p>
  
  <pre><code>$auction-&gt;description
  </code></pre>
  
  <p>How can I accomplish this without forcing all other queries to fetch the description column?</p>
