Question

I have three database table:

product (id, name)

product_has_adv (product,advantage,sort,important)

advantage (id, text)

In ProductModel I def

Answer 1

Using viaTable methods with relations will cause two separate queries, but if you don't need link() method you can use innerJoin in the following way to sort by product_has_advantage table:

public function getAdvantages()
{
    $query = AdvantageModel::find();
    $query->multiple = true;
    $query->innerJoin('product_has_advantage','product_has_advantage.advantage = advantage.id');
    $query->andWhere(['product_has_advantage.product' => $this->id, 'product_has_advantage.important' => 1]);
    $query->orderBy(['product_has_advantage.sort' => SORT_DESC]);
    return $query;
}

Note than $query->multiple = true allows you to use this method as Yii2 hasMany relation.
