我可以在变量设置中使用动态模型吗？

Question

I have this code

 $this->loadModel($model);
 $this->Task->id = $id;
 $this->Task->save($this->data[$model]);

How can I setup the "Task" model so I can make it dynamic because this doesn't work:

 $this->loadModel($model);
 $this->$model->id = $id;
 $this->$model->save($this->data[$model]);

I also tried this with no luck:

 $this->loadModel($model);
 $this->currentModel = $model;
 $this->currentModel->id = $id;
 $this->currentModel->save($this->data[$model]);

try this one...

<?php

// THE DYNAMIC MODEL
App::Import('Model', $model);
$this->DynamicModel = new $model;

// USAGE EXAMPLE

function getModelColumns($model){
App::Import('Model', $model);
$this->DynamicModel = new $model;
print_r($this->DynamicModel->getColumnTypes());exit();
}
