问题描述
我想在后端添加相关模型时调用一个函数. 这可以通过使用数据透视模型来实现，但在这种情况下，必须有一些数据透视，否则将不会触发数据透视事件.
I want to call a function when a related model is added in the backend. This can be achieved by using a pivot model but in that case there must be some pivot data, otherwise the pivot model events are not fired.
我不需要任何数据，只需要监听关系添加事件.
I dont need any pivot data but just to listen for the relation added event.
推荐答案
