Laravel - 基于关系的事件

Question

我有以下型号。

1. Shipment
2. ShipmentPiece

Shipment可以有多个ShipmentPiece个实例。 ShipmentPiece属于Shipment。

当我将新creating附加到saving时，是否存在模型事件（与ShipmentPiece或Shipment相同）？

例如，当我这样做时：

$shipment->shipmentPieces()->save($shipmentPiece);

或

$shipment->shipmentPieces()->saveMany([$piece1, $piece2]);

我想在Shipment类中的boot类中运行一些逻辑。
