title: Best way to display a loading spinner in Django?
body: <p>What is the best way to display a loading spinner in Django during a relatively lengthy server-side processing task?  Is this something that JS/jQuery should handle?</p>
  
  <p>If so, how do I get the button click that starts the server-side processing to initiate the spinner?</p>
  
  <p>Django novice here, so I appreciate any input.  Thanks!</p>
