子类中的 Yii 模型行为继承 AR 模型类

Question

我已经实现了一个 crypt 行为类，它可以附加到 AR 模型上，这样，附加的属性将以加密的形式存储并以解密的字符串形式检索。

class User extends CActiveRecord 
{
    public function behaviors()
    {
        return array(
            'crypt' => array(
            // this assumes that the behavior is in the folder: protected/behaviors/
            'class' => 'application.behaviors.CryptBehavior',
            // this sets that the attributes to be encrypted/decrypted are encryptedfieldname of the model
            'attributes' => array('password'),
            'useAESMySql' => true
           )
        );
    }
}

这工作正常。我也有我的自定义类Myuser，它扩展了User 模型来编写我的自定义函数，这样如果我对我的user 表进行一些更改并重新生成模型，我就不会丢失我自己的函数。

如果我将我的 behavior 函数移动到 MyUser 类，行为不会得到附加并且无法按预期工作。

class MyUser extends User 
{
    public function behaviors()
    {
        return array(
            'crypt' => array(
            // this assumes that the behavior is in the folder: protected/behaviors/
            'class' => 'application.behaviors.CryptBehavior',
            // this sets that the attributes to be encrypted/decrypted are encryptedfieldname of the model
            'attributes' => array('password'),
            'useAESMySql' => true
           )
        );
    }

    public function customfn1()
    {
         //some code goes here...
    }
}

这是有效的解决方案。我需要测试所有场景。感谢@bool.dev 提供的功能。

class MyUser extends User 
{
    public static function model($className=__CLASS__)
    {
       return parent::model($className);
    }

    public function behaviors()
    {
        return array(
            'crypt' => array(
            // this assumes that the behavior is in the folder: protected/behaviors/
            'class' => 'application.behaviors.CryptBehavior',
           // this sets that the attributes to be encrypted/decrypted are encryptedfieldname of the model
            'attributes' => array('password'),
           'useAESMySql' => true
          )
       );
    }

   public static function getUserByID($id)
   {
      //validation of $id goes here..

      return MyUser::model()->findByPk($id);
   }
}

在我的控制器中

$userModel = MyUser::getUserByID(1);

在我看来

$userModel->password; //gives me the decrypted password; for easy understanding, i used password field here....

您还必须将类的static model 函数添加到子类中。就这么多应该可以工作：

public static function model($className=__CLASS__)
{
    return parent::model($className);
}
