Displaying json data on datatables with laravel resources - laravel

Question

I have some data i have stored in my table and i have cast to array and accessing it in my resource like this
<?php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Auth;
class JobRequests extends JsonResource
{
public $preserveKeys = true;
/**
* Transform the resource into an array.
*
* #param \Illuminate\Http\Request $request
* #return array|\Illuminate\Contracts\Support\Arrayable|\JsonSerializable
*/
public function toArray($request)
{
$data = DB::select('select order_data from orders where id=9');
return [
'email' => json_decode($data[0]->order_data)->personal_data->email,
'telephone_number' => json_decode($data[0]->order_data)->personal_data->telephone_number,
'car_registration' => json_decode($data[0]->order_data)->personal_data->car_registration,
'postal_code' => json_decode($data[0]->order_data)->personal_data->postal_address
/**
'commission' => function(){
$final_price = 700;
return (int)$final_price;
}
*/
];
}
}
My data looks like this
{
"personal_data": {
"email": "info#info.com",
"telephone_number": "0999",
"postal_address": "LON",
"car_registration": "GB BHG"
},
"inperson_diagnostic": {
"diagnostic_inspection": "67.30",
"car_wont_start_inspection": "67.30",
"plugin_diagnostic_inspection": "67.30"
},
"tyres": {
"front_wheels": 1,
"rear_wheels": 1,
"wheel_width": 45,
"wheel_profile": 1,
"wheel_rim": 1,
"speed_rating": "w",
"final_price": 90
},
"servicing_and_mot": {
"mot_with_collection_delivery": 75,
"major_service": 304.52,
"full_service": 203.45,
"interim_service": "149.70",
"vehicle_health_check": 50
},
"inspection_services": {
"premium_prepurchase_inspection": 146.38,
"standard_prepurchase_inspection": 104,
"basic_prepurchase_inspection": 86.44
},
"repairs": {
"ABS wheel speed sensor replacement": 964,
"ABS pump replacement": 712,
"Brake pedal switch replacement": 568,
"Air conditioning regas (R1234yf Gas ONLY)": 469
}
}
This is the function i am trying to fetch data with
//Fetch Job Requests
public function jrData(Request $request)
{
//$data = DB::select('select order_data from orders where id=9');
$jobRequest = new JobRequests($request);
$object_json = $jobRequest->toJson();
$object_array = (array)$object_json;
return Datatables::of($object_array)
->addIndexColumn()
->addColumn('action', function($row){
$btn = 'View';
return $btn;
})
->rawColumns(['action'])
->make(true);
}
and this is my blade page
<script>
$(function() {
$('#users-table').DataTable({
processing: true,
serverSide: true,
ajax: '{!! url('jrData') !!}',
columns: [
{ data: 'id', name: 'id' },
{ data: 'email', name: 'email' },
{ data: 'telephone_number', name: 'telephone_number' },
{ data: 'car_registration', name: 'car_registration' },
{ data: 'postal_code', name: 'postal_code' },
{data: 'action', name: 'action', orderable: false, searchable: false}
]
});
});
</script>
This is the data returned by my jrData
{"draw":0,"recordsTotal":1,"recordsFiltered":1,"data":[{"0":"{\"email\":\"info#info.com\",\"telephone_number\":\"0900\",\"car_registration\":\"KGB BHG\",\"postal_code\":\"00200\"}","action":"<a href=\"view_job_request\/\" class=\"edit btn btn-info btn-sm m-2\">View<\/a>","DT_RowIndex":1}],"input":[]}
I get this error on my blade file
DataTables warning: table id=users-table - Requested unknown parameter
'id' for row 0. For more information about this error, please see

How can i display the data in the datatables?

Answer 1

Ok here is an example:
You have
$data = DB::select('select order_data from orders where id=9');
This really isn't going to give you the data you need.
Try doing this:
$data = YourModel::where('id',$id)->first();
$id is a dynamic id so you can run this to grab anything instead of being static. I'm guessing you are doing a post to get the data, so if you send that through it would be $request->id so you just set it to $id = $request->id; now you're fully dynamic in your eloquent.
