Zend Framework 2: Populate ajax table (DataTable) - ajax

Question

Below is snippet of table-ajax.js file from DataTable module.
My question is what will be Ajax url instead of table_ajax.php if I use IndexAction{} in my Controller. I want to display data from database.
var handleRecords = function () {
var grid = new Datatable();
grid.init({
src: $("#datatable_ajax"),
onSuccess: function (grid) {
},
onError: function (grid) {
},
onDataLoad: function(grid) {
},
loadingMessage: 'Loading...',
dataTable: {
"bStateSave": true, // save datatable state(pagination, sort, etc) in cookie.
"lengthMenu": [
[10, 20, 50, 100, 150, -1],
[10, 20, 50, 100, 150, "All"] // change per page values here
],
"pageLength": 10, // default record count per page
"ajax": {
"url": "table_ajax.php", // ajax source
},
"order": [
[1, "asc"]
]// set first column as a default sort by asc
}
});

Firstly you'll need to add a strategy to your viewmanager so you can return json. This is done within your module.config like so:
'view_manager' => array(
...
'strategies' => array(
'ViewJsonStrategy'
),
...
),
I'll just assume you have this DataTableModule imported via your Autoloader. So you can extend or implement the "table_ajax.php" within your controller and override/add a return value as a zf2 JsonModel.
In your Action within your Controller that extends/implements ajax_table.php
...
return new JsonModel($whateverTheResultIs);
...
Now that you have a controller that returns your JSON you'll require to set up a route. This is pretty straight forward it only links to your controller action and since you defined a strategy in your Viewmanager ZF2 does the rest of the pesky ajax stuff for you.
Edit: Rather then extending the table_ajax.php in your controller it probably is a good idea to write a Service which retrieves the information from table_ajax.php.
