title: Django Form is Always Invalid with ChoiceField - Select a Valid Choice
body: <p>I recently added a ChoiceField to my form but now it always returns invalid; I verified this with a 'print(form.is_valid())'. All fields are displayed properly in my template and values are always being passing so I can't fathom why the form is returned as invalid.</p>

  <p>This is online database so I use the modelform  to create the item and the form to search through and pull the results. Therefore, I need both to work. </p>
  
  <p>EDIT:</p>
  
  <p>I discovered it was selecting an invalid choice. Ideas how to fix this?</p>
