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 def

Answer 1

As explained by @arogachev, the viaTable uses two separate queries, which renders any intermediate orderBy obsolete

You could replace the viaTable with an innerJoin as follows, in a similar solution to @MartinM

public function getAdvantages()
{
   return $this->hasMany(AdvantageModel::class, ['pha.product' => 'id'])
       ->innerJoin('product_has_advantage pha', 'pha.advantage = advantage.id')
       ->andWhere(['pha.important' => 1])
       ->orderBy(['pha.sort' => SORT_ASC]);
}

By adjusting the result of hasMany, you are adjusting the query for the target class - AdvantageModel::find(); product_has_advantage can be joined via the advantage identity

The second parameter of hasMany, link, can be viewed as [ query.column => $this->attribute ], which you can now support via the joined product_has_advantage and its product identity

---

Note, when using viaTable, the link parameter can be viewed as if the intermediate query is complete and we are starting from there; [ query.column => viaTable.column ] hence ['id', 'advantage'] in your question
