需要从处理已删除模型的事件中删除SerializesModels特性.

The SerializesModels trait needs to be removed from events that deal with deleted models.

SerializesModels是一个特征，它仅在序列化事件(或作业)时存储模型的ID，而在未序列化事件时从数据库中重新获取模型.

SerializesModels is a trait that only stores the id of the model when the event (or job) is serialized, and refetches the model from the database when the event is unserialized.

这允许排队的进程在运行时从数据库中获取新模型，因此它们不会使用过时的信息运行，但是当您从数据库中删除该行时，这将是不可靠的.

This allows queued processes to get a fresh model from the database when they run so they are not running with outdated information, but this would not be reliable when you're deleting that row from the database.
