use GeoSocio\EntityUtils\ParameterBag;

class User {

    $params = new ParameterBag($data);
    $this->id = $params->getInt('id');
    $this->first = $params->getString('first');

}

创建Trait

将 trait 包含到实体中以添加一个在持久化时添加的 'created' 字段。

use GeoSocio\EntityUtils\CreatedTrait;

class User {

  use CreatedTrait;

}
