Description

request.is_ajax() is deprecated

This means we have to recreate the functionality ourselves if we want to check for an AJAX request. Luckily, the Django developers tell us exactly what we need to do.

We have to recreate the logic from the request.is_ajax() method ourselves, which is only 1 line of code:

request.headers.get('x-requested-with') == 'XMLHttpRequest'

Now we can edit the view to include this check

def ajax_view(request):
  if request.headers.get('x-requested-with') == 'XMLHttpRequest':
    # Get requested data and create data dictionary
    return JsonResponse(data))
