Ok, I'll try to elaborate. again java is foreign to me although I've
spent all day trying to learn some.
Here's the code:
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>
def run_DHM(request) is straight forward then it falls apart.
$.getJSON("/run_DHM/", function(data) {
// do something with result
console.log(data.result);
});
I presume that '$.getJSON("/run_DHM/", function(data)' somehow runs
the run_DHM function? How can it even find the function since it lives
in view.py? '// do something with result'???? I want to send another
page to the client with the results but do I do this here? If not,
what do I do here? What does 'console.log(data.result);' do? Why does
def run_DHM(request) return a HttpResponse? I have a template I want
it to return so shouldn't I use render_to_response? Obviously, I am
not getting how the javascript works so I have no idea how to set this
up. I was hoping there was a pythonic solution :).
I hope this explains my utter confusion sufficiently.
