This works for the top level but what is need is to remove some attributes from a related item say user has one access_card and access_card have some long text details as one of its attribute.

i want to remove that attribute from final result. Is is possible with the method mentioned in link?

Answer 1

Assuming you have a "code" field on access card, you can try something like that:

$users = Users::with('access_card')->get();
$subset = $users->map(function ($user) {
    return collect(
        [
            'id' => $user->id,
            'email' => $user->email,
            'access_card' => $user->access_card->code,
        ]);
});

dd($subset);

Answer 2

User::with(['access_card' => function($query){
    $query->select('code');
} ])->select('id', 'email')->get();

Assumig you want user id and email with an access card and only the card_code
