Django - show loading message during long processing

Question

How can I show a please wait loading message from a django view?

I have a Django view that takes significant time to perform calculations on a large dataset

Another thing you could do is add a javascript function that displays a loading image before it actually calls the Django View.

function showLoaderOnClick(url) {
      showLoader();
      window.location=url;
  }
function showLoader(){
      $('body').append('
Loading...
');
  }

And then in your template you can do:

This will take some time...

Here's a quick default loadingDiv : https://stackoverflow.com/a/41730965/13476073 Note that this requires jQuery.
