Yii Сменить пароль администратора

Я нашел метод, я не знаю, правильный ли ответ в методе или нет.
Я обнаружил, что проблема возникает во время проверки.поэтому создал другую модель под названием пароль изменения для этой операции, проверяйте только три атрибута, которые я указал в правилах.
И это прекрасно сработало.
