Inaccuracy? Edit Entity attributes

The setAttributes() method is needed in order to set the data as it is. That is, so that mutations are not applied.

If you want a fullname attribute that is essentially a derivative of firstName and lastName , you can add a getter.

PHP Code:

public function getFullName(): string
{
    return $this->firstName . ' ' . $this->lastName;
}

$user->fullName // return fullname
