🚀 ¿Qué resuelve este paquete?
-----------------------------

[](#-qué-resuelve-este-paquete)

Yii2 ofrece `loadMultiple` y `validateMultiple`, pero no resuelve el *problema real*:

- Reconstruir N modelos dinámicos enviados por POST
- Detectar elementos eliminados en el frontend
- Crear automáticamente nuevos registros
- Evitar índices rotos y conflictos de ID
- Validación y guardado masivo sencillo

Con una sola línea:

```
$modelos = ModelHelper::createMultiple(MyModel::class, $modelosIniciales);
```

📦 Instalación (Composer)
------------------------

[](#-instalación-composer)

```
composer require jiuly256/yii2-modelhelper
```

🔧 Uso básico en controlador
---------------------------

[](#-uso-básico-en-controlador)

```
use jiuly256\modelhelper\ModelHelper;
use yii\base\Model;
use yii\helpers\ArrayHelper;

public function actionMultiple($id)
{
    $modelos = MyModel::findAll(['parent_id' => $id]);

    if (empty($modelos)) {
        $modelos = [new MyModel(['parent_id' => $id])];
    }

    if (Yii::$app->request->isPost) {
        $oldIDs = ArrayHelper::map($modelos, 'id', 'id');
        $modelos = ModelHelper::createMultiple(MyModel::class, $modelos);
        Model::loadMultiple($modelos, Yii::$app->request->post());

        $newIDs = ArrayHelper::map($modelos, 'id', 'id');
        $deletedIDs = array_diff($oldIDs, $newIDs);

        if ($deletedIDs) {
            MyModel::deleteAll(['id' => $deletedIDs]);
        }

        if (Model::validateMultiple($modelos)) {
            foreach ($modelos as $m) {
                $m->parent_id = $id;
                $m->save(false);
            }
            return $this->redirect(['view', 'id' => $id]);
        }
    }

    return $this->render('multiple', [
        'modelos' => $modelos
    ]);
}
```
