Yii2: BlameableBehavior updates createdByAttribute on every update

[jmisel]

What steps will reproduce the problem?

In model I add behaviors to set actual user on insert:

public function behaviors()
{
    return [
            [
                'class' => BlameableBehavior::className(),
                'createdByAttribute' => 'fk_creator',
                'updatedByAttribute' => false,
                'attributes' => [
                    ActiveRecord::EVENT_BEFORE_VALIDATE => ['fk_creator']
                ]
            ],
                 ];
}

What is the expected result?

Set actual user to fk_creator at insert, not at update.

What do you get instead?

Refresh fk_creator at every update.

See details from attributes property:

List of attributes that are to be automatically filled with the value specified via $value. The array keys are the ActiveRecord events upon which the attributes are to be updated, and the array values are the corresponding attribute(s) to be updated. You can use a string to represent a single attribute, or an array to represent a list of attributes. For example,

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

In your case, you define when before validate, the attribute fk_creator should be updated. When should be something like

'attributes' => [
     ActiveRecord::EVENT_BEFORE_INSERT => ['fk_creator']
]

@marcelodeandrade Quote from api:

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.

So, fk_creator should only be filled at insert, not at update.

[marcelodeandrade]

You are overrind the default behavior from BlameableBehavior when set the attributes. Change to

'attributes' => [
     ActiveRecord::EVENT_BEFORE_INSERT => ['fk_creator']
]
