title: Rails Radio Button for Two Boolean DB Attributes
body: <p>I have an <code>Attendance</code> model that has two <code>Boolean</code> database attributes (<code>:late</code> and <code>:absent</code>) and they both have <code>:default =&gt; false</code>.</p>
  
  <p>I am trying to make a form that simply has 2 radio buttons.  One for late and one for absent.  Of course, the user can select only one of the two.</p>
  
  <p>I've tried so many variations but can't get anything to work.</p>
  
  <p>Can anyone lend me a hand?  I know I could do collection select pretty easily but radio buttons will help the user experience.  Also, I need to keep with the db schema for a bunch of reasons...</p>
  
  <p>Thanks a million!!!</p>
