Can behaviors fill in values before validation?

Yii 2.0
1

I am using TimestampBehavior and BlameableBehavior to set the usual created_at, created_by, etc attributes.
In my rules I use the unique validator where I combine an attribute with the created_by.
The problem I am facing is that created_by is populated after the validation thus validation passes when it should not.
Is there some easy-automated method the behaviors to kick-in before validation or I need to “customize” it (for instance on before validate force-call the behaviors expected to fill in values)?

Solved,

as per the AttributeBehavior can specify on which even the values should be populated.

'attributes' => [
    ActiveRecord::EVENT_BEFORE_INSERT => 'attribute1',
    ActiveRecord::EVENT_BEFORE_UPDATE => 'attribute2',
],

In the blameable instance that would be

[
    'class' => BlameableBehavior::class,
    'attributes' => [
        self::EVENT_BEFORE_VALIDATE => ['created_by', 'updated_by']
    ],
],

Solution is perfect.

But created_by, updated_by should not be part of validation process as long this values are not coming from user input.
