foreach Yii2 -> Getting unknown property - eager loading?

Question

Yii

Hello!
I implement eager loading from the DB
Controller:

$query = Product::find()->where(['category_id' => $id])->with('size');
        $pages = new Pagination(['totalCount' => $query->count(), 'pageSize' => 3, 'forcePageParam' => false, 'pageSizeParam' => false]);
        $products = $query->offset($pages->offset)->limit($pages->limit)->all();
        return $this->render('view', compact('products', 'pages', 'category'));

Product Model

public function getSize(){
        return $this->hasMany(Size::className(), ['product_id' => 'id']);
    }

Model Size

public function getProducts(){
        return $this->hasMany(Product::className(), ['id' => 'product_id']);
    }

view

<?php
foreach($products as $product) {
    echo "<h2>Название : " . $product->name . "</h2>";
    echo "<ul>";
    foreach($product->size as $sizes) {  // no query executed here
        echo "<li>" . $sizes->$size_p . "</li>";
    }
    echo "</ul>";
}
?>

Gives an error messageGetting unknown property: app\models\Size::

var_dump $product to studio. If everything is correct, then you will have your access model by the size key directly in the object.
