 When the `validate()` method is called, it does the following steps to perform validation:
 
-1. Determine which attributes should be validated by checking the current [[yii\base\Model::scenario|scenario]]
-   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.

 According to the above validation steps, an attribute will be validated if and only if it is
 an active attribute declared in `scenarios()` and is associated with one or multiple active rules
 declared in `rules()`.
