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

Answer 1

a more straightforward approach is to generate a wait page with your gif etc. and then use the javascript

window.location.href = 'insert results view here';

to switch to the results view which starts your lengthy calculation. The page wont change until the calculation is finished. When it finishes, then the results page will be rendered.
