I have a long process wherein my application communicates with a server, saves a model based on the server's response, and restarts its communication. I'd like to present the user with a loading page which updates whenever a model is saved. For example:
Working on request 1...
Saving model 1...
Working on request 2...
Saving model 2...
Finished task.

I've read through this(jango - show loading message during long processing) and its links; the first suggestion would not work, and the second requires threading, caching, etc. I've also read through the documentation for Signals.
Let's say the model which is saved is ModelAfterResponse. My view might look like this:
@receiver(post_save, sender=ModelAfterResponse)
def loading_page(sender, instance, created, **kwargs):
model_name = kwargs['instance'].name
return render(request, 'name/javascript_template.html', {"name": name}, content_type="application/x-javascript")
And the javascript_template.html might look like this:
<script>
$('#some_loading_page_specific_div').innerHTML = "Working on " + {{ name }}
</script>
This is just quick mock-code—but do I have the gist of it? When I decorate a function as above, and do something simple like return HttpResponse(":D"), nothing happens—everything continues running and :D is nowhere to be found.
I believe I'm on the right track. Is there a simple way to accomplish what I'm looking for?
