Yii implements querying a piece of data based on id

Yii implements the method of querying a piece of data based on id as follows:

1. Model layer

public function selectone($ag_id=''){
        return $this->findBySql("SELECT * FROM agency where ag_id=$ag_id")->asArray()->one();
    }

(Recommended tutorial: yii framework)

2. Controller layer

$ag_id = $_GET['ag_id'];
$data = $model -> selectone($ag_id);

3. View layer

./index.php?r=about/agency&ag_id=<?php echo $value[&#39;ag_id&#39;] ?>
