title: concat two fields activerecord
body: <p>I'm so used to oracle where you can simply </p>
  
  <pre><code>concat(field1, ' ', field2)
  </code></pre>
  
  <p>but if I'm using activerecord to find the field1 and field2, and I need a space in between, how do I accomplish this?</p>
  
  <p>Cheers for all your help </p>
