* ```php
* use yii\behaviors\BlameableBehavior;
*
* public function behaviors()
* {
* return [
* BlameableBehavior::className(),
* ];
* }
* ```
*
* By default, BlameableBehavior will fill the `created_by` and `updated_by` attributes with the current user ID
* when the associated AR object is being inserted; it will fill the `updated_by` attribute
* with the current user ID when the AR object is being updated. If your attribute names are different, you may configure
* the [[createdByAttribute]] and [[updatedByAttribute]] properties like the following:
*
* ```php
* public function behaviors()
* {
* return [
* [
* 'class' => BlameableBehavior::className(),
* 'createdByAttribute' => 'author_id',
* 'updatedByAttribute' => 'updater_id',
* ],
* ];
* }
