not recieved the data in laravel datatable - php

Question

I am trying to fetch data using datatable in laravel. My
view is :
<script type="text/javascript">
var oTable;
$(document).ready(function () {
oTable = $('#data').DataTable({
"processing": true,
"serverSide": true,
"order": [],
"columns":[
{"data":"start_date"},
{"data":"end_date"},
{"data":"client_id"},
{"data":"created_at"},
{"data":"actions"}
],
"ajax": "{{ url('contract') }}" + ((typeof $('#data').attr('data-id') != "undefined") ? "/" + $('#id').val() + "/" + $('#data').attr('data-id') : "/data")
});
});
function deleteClient(id){
}
</script>
public function data(Datatables $datatables)
{
$contObj = new Contract;
$conttt = $contObj->get()
->map(function ($conttt) {
return [
'id' => $conttt->id,
'start_date' => $conttt->start_date,
'end_date' => $conttt->end_date,
'client_id' => $conttt->user_id,
'created_at' => $conttt->created_at
];
});
return $datatables->collection($conttt)
->addColumn('actions', '#if(Sentinel::inRole(\'admin\'))
<a href="{{ url(\'contract/\' . $id . \'/edit\' ) }}" title="{{ trans(\'table.edit\') }}">
<i class="fa fa-fw fa-pencil text-warning "></i> </a>
#endif
<a href="{{ url(\'contract/\' . $id . \'/show\' ) }}" title="{{ trans(\'table.details\') }}" >
<i class="fa fa-fw fa-eye text-primary"></i> </a>
')
->removeColumn('id')
->rawColumns(['actions'])->make();
}
but when I am getting this data as :
"data":[{"start_date":null,"end_date":null,"client_id":"3","created_at":{"date":"2018-08-07 10:13:46.000000","timezone_type":"3","timezone":"UTC"},"actions":" <a href=\"http:\/\/billing.mj.milesweb.cloud\/files\/public\/contract\/1\/edit\" title=\"Edit\">\n <i class=\"fa fa-fw fa-pencil text-warning \"><\/i> <\/a>\n <a href=\"http:\/\/billing.mj.milesweb.cloud\/files\/public\/contract\/1\/show\" title=\"Show\" >\n <i class=\"fa fa-fw fa-eye text-primary\"><\/i> <\/a>\n "}
When I see this data in datatable then I see in field created_at the data shown there is [object Object] while in json it is OK. Please help me to show the proper data in datatable

Answer 1

It's because created_at is a Carbon object and you need a string. For 'created_at', try returning the following:
\Carbon\Carbon::createFromFormat('Y-m-d H:i:s', $conttt->created_at)->format('m/d/y h:i A')

Answer 2

By default created_at and updated_at are the carbon class object. You need to convert it into your own format:
$conttt = $contObj->get()
->map(function ($conttt) {
return [
'id' => $conttt->id,
'start_date' => $conttt->start_date,
'end_date' => $conttt->end_date,
'client_id' => $conttt->user_id,
'created_at' => $conttt->created_at->format('d-m-Y')
];
});
You also can write this code into Your model class. For that you need to user Laravel mutators.
Good Luck!!!

Answer 3

you can editColoumn in datatable like this:
return Datatables::of($conttt)
->editColumn('created_at', function($conttt) {
return $conttt->created_at->format('d M Y H:i:s');
})
->make(true);

Answer 4

try it
1)
$contObj = new Contract;
$conttt = $contObj->get()
->map(function ($conttt) {
return [
'id' => $conttt->id,
'start_date' => $conttt->start_date,
'end_date' => $conttt->end_date,
'client_id' => $conttt->user_id,
'created_at' => date('Y-m-d h:s:i', strtotime($conttt->created_at))
];
});
2)
$contObj = Contract::all();
