You are not returning the HttpResponse object from please_wait(). But anyway,
doesn't work that way. At least with django.
What you can do is render a normal html with the message "Please wait",
then perform an ajax call to start the calculations and finally return
a json response
to display the result in the client-side.
Roughly:
def please_wait(request):
# ... setup context or something
return render_to_response("please_wait.html")
def run_DHM(request)
# ... perform calculations and collect the result in a dict
data = {"result": something}
return HttpResponse(json.dumps(data), mimetype="application/json")
# using jquery in your html
<script type="text/javascript">
$.getJSON("/run_DHM/", function(data) {
// do something with result
console.log(data.result);
});
</script>
