/** |
|
* BlameableBehavior automatically fills the specified attributes with the current user ID. |
|
* |
|
* To use BlameableBehavior, simply insert the following code to your ActiveRecord class: |
|
* |
|
* ```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 [[attributes]] property like the following: |
|
* |
|
* ```php |
|
* public function behaviors() |
|
* { |
|
* return [ |
|
* [ |
|
* 'class' => BlameableBehavior::className(), |
|
* 'attributes' => [ |
|
* ActiveRecord::EVENT_BEFORE_INSERT => 'author_id', |
|
* ActiveRecord::EVENT_BEFORE_UPDATE => 'updater_id', |
|
* ], |
|
* ], |
|
* ]; |
|
* } |
|
* ``` |
