CakePHP中配置AppModel避免中文乱码

<?php
/* Customer Model parent class */
class AppModel extends Model {
    public $actsAs = array('Containable');
    public function beforeFind(){
        $this->query('set names utf8');
    }
    public function beforeSave(){
        $this->query('set names utf8');
        return true;
    }
}
?>
