ActiveRecord where and order on via-table

Question

I have three database table:

product (id, name)

product_has_adv (product,advantage,sort,important)

advantage (id, text)

In ProductModel I defined this:

public function getAdvantages()
    {
        return $this->hasMany(AdvantageModel::className(), ['id' => 'advantage'])
            ->viaTable('product_has_advantage', ['product' => 'id']);
    }

I get the advantages without any problems.

But now I need to add a where product_has_advantage.important = 1 clausel and also sort the advantages by the sort-columen in the product_has_advantage-table.

How and where I have to realize it?

Answer 1

public function getAdvantages()
{
    return $this
        ->hasMany(AdvantageModel::className(), ['id' => 'advantage'])
        ->viaTable('product_has_advantage', ['product' => 'id'])
        ->andWhere(['important' => 1])
        ->orderBy(['sort' => SORT_DESC]);
}
