title: Rails select random record
body: <p>I don't know if I'm just looking in the wrong places here or what, but does active record have a method for retrieving a random object?</p>
  
  <p>Something like?</p>
  
  <pre><code>@user = User.random
  </code></pre>
  
  <p>Or... well since that method doesn't exist is there some amazing "Rails Way" of doing this, I always seem to be to verbose. I'm using mysql as well.</p>
