How to correctly set a selection through a linked table in Yii2?

Question

Yii

Let's say we have three tables:

• user - users
  
• currency - selected currency of each user
  
• user_currency - link table
  

user_currency binds the user and currency tables with a foreign key
How do I set a currency selection for the User model in Yii2?

public function getCurrency() {
 ...
}

Is it just like that?

public function getCurrency() {
        $userCurrencyModel = UserCurrency::find()->where(['user_id' => $this->id])->one();
        return $userCurrencyModel->currency;
    }

Answer 1

public function getCurrency() {
    return $this->hasMany(Currency::className(), ['id' => 'currency_id'])
      ->viaTable('user_currency', ['user_id' => 'id']);
}
