Print output to webpage Django

Question

I currently have a long running script which produces various output. What I want to do is have this script run when a button on my webapp is pressed, and for the output to be displayed in real time in a text area on the webpage. I was wondering the simplest way to achieve this using Django.

If you are talking about real time output then you need to use AJAX.

To set off the script, in the webpage you can have a button that sends an AJAX request.

function ajax_call_model(data_JSON_Request, object_id){
    $(function jQuery_AJAX_model(){
        $.ajax({
          type: 'GET',
          url: '/ajax_request/',
          data: something,
          datatype: "json",
          success: function(data) {
            $("#output_id").html(data);
          },//success
          error: function() {alert("failed...");}
        });//.ajax
      });//jQuery_AJAX
    };//ajax_call

In views you will have something like this:

def ajax_request(request):
    something = request.GET.get('something', '')# Receives from AJAX
    output = #Does something with the request
    jsonDump = json.dumps(str(output))

    return HttpResponse(jsonDump, content_type='application/json')
