Class yii\behaviors\BlameableBehavior

BlameableBehavior automatically fills the specified attributes with the current user ID.

To use BlameableBehavior, insert the following code to your ActiveRecord class:

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.

Because attribute values will be set automatically by this behavior, they are usually not user input and should therefore not be validated, i.e. created_by and updated_by should not appear in the rules() method of the model.

If your attribute names are different, you may configure the $createdByAttribute and $updatedByAttribute properties like the following:

public function behaviors()
{
    return [
        [
            'class' => BlameableBehavior::className(),
            'createdByAttribute' => 'author_id',
            'updatedByAttribute' => 'updater_id',
        ],
    ];
}
