title: Rails: read integer from tinyint
body: <p>I have a RoR + MySQL setup. In the database there is a Tinyint field <em>t</em>. When I read the value of <em>t</em> from Rails I get <em>true</em> or <em>false</em> because a Tinyint field is interpreted by Rails as boolean. So far so good. </p>
  
  <p>How do I read this field <em>t</em> as an actual integer from Rails?</p>
