javascript - mongoose 怎么插入嵌套数组？

Answer 1

If I understand your idea correctly, FYI:

1. The ref of Mongoose schema is mainly used to facilitate the association between multiple collections in queries: populate;

2. When inserting data, you need to handle the insertion logic yourself, insert different collections separately, and keep the ObjectId of the ref in different collections consistent

For reference.
