Usage

$user = new App\Models\User;
$user->setForename('Andrew');
$user->setSurname('Dyer');

var_dump($user->present()->name); // Andrew Dyer

View Presenter

All presenters must be an instance of Anddye\ViewPresenters\PresenterInterface and ideally should extend Anddye\ViewPresenters\AbstractPresenter - which will implement the required interface by default.

namespace App\Presenters;

use Anddye\ViewPresenters\Presenter;
use App\Models\User;

class UserPresenter extends Presenter
{
    protected User $user;

    public function __construct(User $user)
    {
        $this->user = $user;
    }

    public function defaultAttributes(): array
    {
        $data = [];
        $data['id'] = $this->user->getId();
        $data['forename'] = $this->user->getForename();
        $data['surname'] = $this->user->getSurname();

        return $data;
    }

    public function name(): string
    {
        return $this->user->getForename() . ' ' . $this->user->getSurname();
    }
}

Use presenters

Models can use the Anddye\ViewPresenters\UsesPresentersTrait trait to access the present() method. Presenter types must be defined in a $presenters property. By default the default type will be used when this method is called. Custom types can be defined and used by passing the key as an argument to the present() method.

namespace App\Models;

use Anddye\ViewPresenters\HasPresenters;
use App\Presenters\UserPresenter;
use App\Presenters\UserSubscriptionPresenter;

class User
{
    use HasPresenters;

    protected int $id;
    protected string $forename;
    protected string $surname;
    protected array $presenters = [
        'default' => UserPresenter::class,
        'subscription' => UserSubscriptionPresenter::class
        // ...
    ];

    // ...

}

// ...

$data = $user->present('subscription')->defaultAttributes;
