Solidity and Etheruem:使用工厂模式处理事件

我正处于学习坚固性和安全帽的初级阶段。我找到了一个似乎相当不错的教程,我能够从下面的示例中获得代码: https://dev.to/dabit3/building-scalable-full-stack-apps-on-ethereum-with-polygon-2cfb .假设我想扩展这个示例,并在其中添加工厂模式功能。如果一个方法是通过工厂方法调用的,我如何确保事件通过工厂方法传播出去?在这种情况下,我将如何处理示例中的事件。js文件?

/* Places an item for sale on the marketplace */
