title: 'Tag' object has no attribute 'count'
body: <p>I keep getting this error when I go to the development server that the 'Tag' object has no attribute 'count'.  I don't understand why the error comes up in line 117 when tag.count didn't generate any errors when used in the previous lines of code?  Thanks!</p>
  
  <p>Here's the error message:</p>
