Select relationship and "virtual" title attribute

Hello, I have a Customer model with a first_name and last_name field. A virtual field full_name which represents the concat of these 2 fields. In another resource, which has an belongsTo Customer relationship, I'd like a select based on full_name.

Forms\Components\Select::make('customer_id')
    ->searchable()
    ->relationship(
        name: 'customer',
        titleAttribute: 'email' # working well with email, but I would like to filter by full_name instead of email
    ),

Forms\Components\Select::make('customer_id')
    ->searchable()
    ->relationship(
        name: 'customer',
        titleAttribute: 'email' # working well with email, but I would like to filter by full_name instead of email
    ),

And what happens when you use full_name as the titleAttribute?

In Customer model

public function fullName(): Attribute
{
    return new Attribute(
        get: fn () => "{$this->first_name} {$this->last_name}"
    );
}

public function fullName(): Attribute
{
    return new Attribute(
        get: fn () => "{$this->first_name} {$this->last_name}"
    );
}

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'customers.full_name' in 'field list'

select
  `customers`.`full_name`,
  `customers`.`id`
from
  `customers`
where
  `customers`.`deleted_at` is null
order by
  `customers`.`full_name` asc

select
  `customers`.`full_name`,
  `customers`.`id`
from
  `customers`
where
  `customers`.`deleted_at` is null
order by
  `customers`.`full_name` asc

My engine is mariadb, even if I modify the query with something like ->addSelect(DB::raw("CONCAT(customers.first_name, ' ', customers.last_name) as full_name") , the engine doesn't allow to filter on this...

you could create a virtual column

$table->string('full_name')->virtualAs('concat(first_name, \' \', last_name)');

$table->string('full_name')->virtualAs('concat(first_name, \' \', last_name)');

nice idea, it can solve my issue, but I'm curious if there is a way to solve that without a schema change thanks a lot, I mark as solved!

I think the third param lets you modify the query and you could add the second where clause
