The Loadmodel Controller Method: Which Table Will Be Searched?

[KeepLearning]

Version 0.5

 

Loading a Single Model

 

The following two examples work together. The second calls the first. I believe the purpose is to retrieve a record from a table. And I believe each occurrence of $id represents the primary key value of the particular record we want.

 

My question is, how do these functions know which table to search in? 

 

page 136:

 

public function loadModel($id) {

$model = Page::model()->findByPk($id);

if ($model===null) {

throw new CHttpException(404, 'The requested page

does not exist.');

}

 

Page 139:

public function actionView($id){

$this->render('view',array(

'model'=>$this->loadModel($id),

));

}

They know what database table to search in because of the model type. The Page model is linked to the page table.
