laravel datatables search in addColumn - laravel

Question

I use laravel/datatables to list data.
I manipulated my datalist with addColumn function.
However I am not able to use search in view for added columns.
Because search is working according to database rows.
Datatables works fine but in the view search area is not working. Because there isnt any fullname row in database table.
Here you can find my codes (I want to search for fullname but I can't)
Order Model
public function getFullname()
{
return json_decode($this->getAttribute('delivery_adress'))->fullname;
}
OrderController.php
if ($request->ajax()) {
return datatables()->of(Order::query())
->addColumn('fullname', function (Order $order) {
return $order->getFullname();
})->addColumn('city', function (Order $order) {
return $order->getCity();
})->addColumn('product_id', function (Order $order) {
return $order->product->title;
})->make(true);
}
Orders Blade / Datatables code
"pageLength": 10,
processing: true,
serverSide: true,
ajax: 'orders',
columns: [
{ data: 'id', name: 'id'},
{ data: 'fullname', name: 'fullname', defaultContent: '-' , orderable: false },
{ data: 'city', name: 'city', defaultContent: '-', orderable: false },
{ data: 'product_id', name: 'product_id', className: 'd-none d-sm-table-cell', defaultContent: '-' },
{ data: 'totalPrice', name: 'totalPrice', className: 'd-none d-sm-table-cell', defaultContent: '-' },
],
edit:
Finally, I found solution
{data: 'added_column', name: 'actual_column_name'}

Make sure to have relationship into Order model like this:
public function user()
{
return $this->belongsTo('App\User');
}
Try to update like this :
...
->addColumn('fullname', function (Order $order) {
return $order->user->fullname;
})
...
