Why is the rbac button highlighted in the role?

Question

Yii

I have the system role, but it's not possible to hide the button for my role

<?php if(!Yii::$app->user->can('system') or !Yii::$app->user->can('shop')):?>
    <?= Html::a('Создать заказ', ['create'], ['class' => 'btn btn-success']) ?>
       	<?php endif; ?>

So that I do not paint every role

<?php if(!Yii::$app->user->can('system') or !Yii::$app->user->can('shop')):?>
    <?= Html::a('Создать заказ', ['create'], ['class' => 'btn btn-success']) ?>
       	<?php endif; ?>

Answer 1

2 identical pieces of code?
create a rule for rbac "createOrder" and connect it to the shop and system roles.
