Yii2 ActiveRecord getting new relation after eager loading

I have a project in Yii2 where I have two models in a one-to-one relation.

The two models are Plan and Subscription, and each has a getSubscription and getPlan method respectively.

I am eager loading a large group of them by using with:

$plans = Plan::find()->with('subscription')->all();

However, I am modifying some of the Plans subscription_id with:

$plan->subscription_id = 5;
$plan->save();

The problem is that now $plan->subscription contains the original Subscription, and not the Subscription with the new id.

Is there a way to make Yii2 grab the new Subscription, only after the id has been updated (and not lazy load all of the Subscriptions)?

If I do not misunderstand, you can do as this

<?php

use yii\db\ActiveRecord;

class Plan extends ActiveRecord
{
    public function init()
    {
        $this->on(self::EVENT_AFTER_UPDATE, [$this, 'afterUpdateHandler']);
    }

    /**
     * @param \yii\db\AfterSaveEvent $event
     */
    public function afterUpdateHandler($event)
    {
        if (isset($event->changedAttributes['subscription_id']))
        {
            $this->subscription = NULL;
        }
    }

    // ...
}

?>

Next time you call $plan->subscription, the subscription your Plan associated with will be retrofitted.

Instead of implementing it as an event handler, you could also rewrite the afterSave method.
