I am using Yajra's DataTables server side processing. I can see the JSON data but the table is not being populated.
I managed to get DataTables working with client side processing, but as I will eventually have > 50,000 rows of data, I decided to try and implement server side processing by downloading Yajra's DataTables for Laravel 5.8.
When I call my route, I see the data in a JSON format, but I am not seeing the table at all. It says "draw: 0", so I guess there is an issue with drawing the table?
I have tried various solutions mentioned on stack overflow and the official DataTables website, however none seem to work for me. E.g.
- DataTables json is not processed (in Laravel)
- jQuery Datatables - Table not populated for Ajax response
- https://datatables.net/forums/discussion/45444/populate-table-body-with-ajax
The JSON data that I see when I call my route is as follows:
{
"draw": 0,
"recordsTotal": 3,
"recordsFiltered": 3,
"data": [
{
"id": "1",
"customerNr": "98764",
"orderNr": "23478",
"pallet_id": "66788",
"status_id": "2",
"created_by": "Sara",
"created_at": "04 Jul 2019",
"updated_at": "2019-07-09 07:23:20"
},
{
"id": "2",
"customerNr": "99999",
"orderNr": "22222",
"pallet_id": "22335",
"status_id": "1",
"created_by": "Sophie",
"created_at": "04 Jul 2019",
"updated_at": "2019-07-04 08:26:28"
},
{
"id": "3",
"customerNr": "54657",
"orderNr": "89856",
"pallet_id": "11228",
"status_id": "1",
"created_by": "Markus",
"created_at": "08 Jul 2019",
"updated_at": "2019-07-08 06:59:42"
},
],
"input": []
}
Here are the relevant files from my Laravel project:
web.php:
Route::get('returned-shipment', ['uses'=>'ReturnedShipmentController@index', 'as'=>'returned-shipment.index']);
ReturnedShipmentController:
public function index(
{
return DataTables::of(ReturnedShipment::all())->make();
}
index.blade.php:
<div class="row">
<div id="tbl" class="col-sm-12">
<table id="overview" class="cell-border display">

<th>Zustand</th>

<tfoot class="tbl-bottom">

</table>
</div>
</div>
<script>
$(document).ready(function () {
var startingStatus = 'angelegt';
var table = $('#overview').DataTable({

'</select>'
},
initComplete: function () {
/**

*/
this.api().columns([3]).every(function () {
var column = this;
var select = $('<select><option value="">alle</option></select>')
.appendTo($(column.header()))
.on('change', function () {
var val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
column
.search(val ? '^' + val + '$' : '', true, false)
.draw();
});
/**

*/
$(select).click(function (e) {
e.stopPropagation();
});
/**
* Once an option in the drop-down next to status has been selected, you can read the text in
* the drop-down
*/
column.data().unique().sort().each(function (d, j) {
if (startingStatus === d) {
select.append('<option SELECTED value="' + d + '">' + d + '</option>')
} else {
select.append('<option value="' + d + '">' + d + '</option>')
}
});
/**
* When drop-down is clicked on, search field is cleared. Otherwise search field must be
* manually cleared before using the drop-down.
*/
$(select).on('click', function () {
table.search(" ").draw();
});
});
}
});
});
</script>
I am expecting to see the table being populated with the data.
If I need to provide any more code or explain something further, please don't hesitate to ask. I am quite new to Laravel and DataTables, so I would greatly appreciate your help.
Thanks in advance! :)
I have checked your current code and checked your JSON. Your JSON file seems to be invalid.

This is the correct format. The comma after the last object in your data array needs to be removed. Can you confirm this solves your issue? I got datatables working without this comma.
