actionUpdate on Multi Model form

How can I update through a multimodel form in Yii?

If my create action is

public function actionCreate()
{
    $model = new Model;
    $model2 = new Model2;
    $model3 = new Model3;

Normally in update action I will use

public function actionUpdate($id) 
{
    $mode开发者_Python百科l = $this->loadModel($id, 'Model');

But how to I handle the others models (Model2 and Model3). I want to be able to update all models at the same time.

Did you update your "loadModel" method to use different models, something like:

public function myLoadModel($id, $m='Model')
{
    $model=$m::model()->findByPk((int)$id);
    if($model===null)
        throw new CHttpException(404,'The requested page does not exist.');
    return $model;
}

And use that for your update functions.

I had the same problem. This is how I solved it:

public function loadModel($id)
{
    $model=Model::model()->with('model2', 'model3',...)->findByPk((int)$id);
    if($model===null)
        throw new CHttpException(404,'Page not found.');
    return $model;
}

Hope it to help you.
