It seems like hasOne() must be provided by classes using this trait. How about adding it as abstract method to this trait?

    /**

    public function onAssignOperator($event)

The parameter $event is not used and could be removed.

    {
        $identity = Yii::$app->user->identity;
        if (empty($identity)) {
            return null;

$behaviors was never initialized. Although not strictly required by PHP, it is generally a good practice to add $behaviors = array(); before regardless.

                'class' => BlameableBehavior::class,

        return [];
    }
