How Can I Set Global Validation Rule - YII2

Question

I have started with YII2 just today. i have installed it successfully and also created required Model, Controllers & views in that using CRUD.

Now my question is as below:

I want to create one Global Validator Rule which we can use in throughout the Models in system.

What i have tried so far:

For that i have created one new model file(FormValidator) in common folder and generate one custom rule method in it.

common/model/FormValidator.php

namespace common\models;

use Yii;
use yii\base\Model;

class FormValidator extends \yii\db\ActiveRecord {

}

then i tried to extend this model file to my frontend model file. but its not working.

frontend/model/Customerprofile.php

namespace frontend\models;

use Yii;
use common\models\FormValidator;    

class Customerprofile extends FormValidator{

}

It's throw below error message:

PHP Fatal Error – yii\base\ErrorException

Class 'common\models\FormValidator' not found

I don't know what i have missing in all these process, if anyone of you help me out from this, would be much appreciated!

Thanks in Advance.

如果要为模型扩展某个主类，则只需扩展CActiveRecord，然后您的模型将扩展此主类。
