-   against the scenarios declared in [[yii\base\Model::scenarios()]]. These attributes are the active attributes.
-2. Determine which rules should be applied by checking the current [[yii\base\Model::scenario|scenario]]
-   against the rules declared in [[yii\base\Model::rules()]]. These rules are the active rules.
