getRelation() public méthode

A relation is defined by a getter method which returns an ActiveQueryInterface object. It can be declared in either the Active Record class itself or one of its behaviors.
public getRelation ( string $name, boolean $throwException = true ) : yii\db\ActiveQueryInterface | ActiveQuery
$name string the relation name, e.g. `orders` for a relation defined via `getOrders()` method (case-sensitive).
$throwException boolean whether to throw exception if the relation does not exist.
Résultat yii\db\ActiveQueryInterface | ActiveQuery the relational query object. If the relation does not exist and `$throwException` is `false`, `null` will be returned.
 /**
