Yii get Model as parameter

I am trying to modify 1 controller to work with 2 models. This is what I have done with loadModel function in my controller

public function loadModel($id, $_model)
{
    if (isset($_model)){
        $model=$_model::model()->findByPk($id); // syntax error, unexpected "::"
        if($model===null)
            throw new CHttpException(404,'The requested page does not exist.');
        return $model;
    } else {
        $model=Foods::model()->findByPk($id);
        if($model===null)
            throw new CHttpException(404,'The requested page does not exist.');
        return $model;
    }
}

As you can see I want to create optional parameter for this function where second parameter will be the Model. Can you help me to achieve this?

Solution

  • You can't use string as class name to call static method. Just instantiate model and call findByPk:

    if (isset($_model)){
    $model = new $_model;
    $model= $model->findByPk($id);
