Yii2 RegularExpressionValidator

Всем привет, пытаюсь прикрутить валидатор http://www.yiiframework.com/doc-2.0/yii-validators-regularexpressionvalidator.html

Пишу

$validator = new RegularExpressionValidator();

$validator->pattern = '/[^а-яА-Я.,!()0-9 ]/u';

Получаю

Почему ?

class SModelForm extends Model

{

    public $s1;

    public $s2;

    public $s3;

    public $s4;

    public $s5;

    public $s6;


	public function rules() {

        return [

    		[['s1', 's2', 's3', 's4', 's5', 's6'], 'match', 'pattern' => '/^\d+(?:\.\d+)?$/', 'message'=>'Only numerical values allowed'],

		];

    }

}

This is passed as an array and each of these (in this case only one) is processed using

        foreach ($this->getActiveValidators() as $validator) {

            $validator->validateAttributes($this, $attributeNames);

        }

No idea how to use it standalone as you intend to use.

Thanks for your reply, this works

$validator = new \yii\validators\RegularExpressionValidator(['pattern' => '/[^а-яА-Я.,!()0-9 ]/u']);

$validator->not = true;

// etc.
