I have a project with laravel and datatable using yajrabox, it stuck in relationship sort

```
<?php

namespace App\DataTables;
use DB;
use App\Models\Kabupaten;
use Yajra\DataTables\Html\Button;
use Yajra\DataTables\Html\Column;
use Yajra\DataTables\Html\Editor\Editor;
use Yajra\DataTables\Html\Editor\Fields;
use Yajra\DataTables\Services\DataTable;

class KabupatenDataTable extends DataTable
{
    /**
     * Build DataTable class.
     *
     * @param mixed $query Results from query() method.
     * @return \Yajra\DataTables\DataTableAbstract
     */
    public function dataTable($query)
    {
        return datatables()
            ->eloquent($query)
            ->addIndexColumn()

                 ->addColumn('kordinat', function(Kabupaten $kabupaten) {
                return $kabupaten->koordinat_bujur.",".$kabupaten->koordinat_lintang;
                 })
                //  ->addColumn( 'action', function($data){ // $data is data od current row in table 
                //     return view( 'kabupaten.action', [ 'data' => $data ] );
                // } );
            ->addColumn('action', 'kabupaten.action');
    }

    /**

     */
    public function query(Kabupaten $model)
    {
        // return $model->newQuery()->with('provinsi');
        return  Kabupaten::with('provinsi')->select('kabupaten.*','provinsi.provinsi');
    }

    /**
     * Optional method if you want to use html builder.

    public function html()

        return $this->builder()
                    ->setTableId('kabupaten-table')

                    ->parameters([
                        'buttons' => ['excel'],
                    ])
                    ->buttons(
                        Button::make('create'),
                        Button::make('export'),
                        Button::make('print'),
                        Button::make('reset'),
                        Button::make('reload')
                    );
    }

    /**
     * Get columns.
     *
     * @return array
     */
    protected function getColumns()
    {
        return [

            Column::make('DT_RowIndex')->title('No')->orderable(false)->searchable(false),
            Column::make('provinsi.provinsi'),
            Column::make('status'),
            Column::make('kabupaten')->title('Nama kabupaten'),
            Column::make('ketinggian'),
            Column::make('kordinat')
            ->exportable(false)
            ->printable(false),
            // Column::make('keterangan'),
            Column::computed('action')
            ->exportable(false)
            ->printable(false),
        ];
    }

    /**
     * Get filename for export.
     *
     * @return string
     */
    protected function filename()
    {
        return 'Kabupaten_' . date('YmdHis');
    }
}

```

this is my kabupaten datatable class

```
<form id="delete_form" method="POST"> 
    @csrf
 @method('DELETE')</form>
 <a type="button" href="{{route('adm.kabupaten.show', ['id' => $id])}}" class="btn btn-just-icon btn-round btn-sm btn-info" data-toggle="tooltip" data-placement="bottom" title="detail">
     <i class="fa fa-eye"></i>
 </a>
 <a href="{{route('adm.kabupaten.edit', ['id' => $id])}}" class="btn btn-just-icon btn-round btn-sm btn-primary" data-toggle="tooltip" data-placement="bottom" title="ubah">
     <i class="fa fa-edit"></i>
 </a>
 <a href="#" data-url="{{ route('adm.kabupaten.destroy', $id) }}" class="btn btn-just-icon btn-round btn-sm btn-danger" onclick="return deleteConfirm(this);">
     <i class="fa fa-trash"></i>
 </a>

<script>
 $(function() {
     $('[data-toggle="tooltip"]').tooltip();
 })
</script>

```

and this is my action column.

provinsi model

```
public function kabupaten()
    {
        return $this->hasMany(Kabupaten::class);
    }

```

and kabupaten model

```
public function provinsi()
    {
        return $this->belongsTo(Provinsi::class);
    }

```

my question are why $id in **kabupaten.action** return provinsi.id instead of kabupaten.id

and i have try

```
return  Kabupaten::with('provinsi')->select('kabupaten.*','provinsi.provinsi');

```

The $id return kabupaten.id but when I try to sort column, it said column provinsi.provinsi not found because the yajra not join my query.

If there anything wrong with my code.

Thanks
