<p><code>dump_object</code> dumps the hash returned by <code>get_columns</code>. If the result source includes virtual columns defined with <code>resultset_attributes</code>, they get dumped as well. Then populating from fixtures fails because the virtual columns don't exist in the table.</p>
<p>This change dumps only columns defined in <code>columns_info</code>, effectively excluding the virtual columns.</p>
<p>See t/lib/DBICTest/Schema3.pm for an example of a virtual column.</p>
<p>I'm not sure this in the best (or correct) way to exclude virtual columns, or even if defining virtual columns this way is correct. But this fixes an issue I encountered in an existing database and passes all other tests as well.</p>
<p>Two commits. The first is a failing test. The second is the fix.</p>
