有使用了官方文档的这种方法，也不对,不应该是删除他的中间关系表吗

生成的sql竟然是操作user的这个表

当前版本使用的是gorm.io/gorm v1.23.8

@jinzhu 能看下这个问题吗？我发现这个确实是个bug

If you think there is a bug, please create a PR to describe it in the playground.
If you think this is an obvious bug, you should at least provide the simplest reproducible code snippet in your question.
You just copied some code, even the model defined and updated are not the same. No one wants or has the energy to guess what's wrong with you.
