title: Rails Checkbox boolean values not passing to database
body: <p>Can't seem to get the checkbox to pass true to my database</p>
  
  <p>this is the middle part of my devise sign-up form.</p>
  
  <pre><code>      &lt;div class="form-group"&gt;
      &lt;%= check_box_tag :admin, checked = true %&gt;
      &lt;%= label_tag :admin %&gt;
    &lt;/div&gt;
  </code></pre>
  
  <p>I've set the admin field to default to false in my schema.rb when Null</p>
  
  <p>I don't know where else to start.</p>
  
  <p>If you guys need any screenshots of controllers, etc. </p>
  
  <p>Please comment :)</p>
