在猫鼬中映射多对多关系的最佳方法是什么

Question

I am building an immunization tracker. There are 2 models:

1. patient
2. vaccine

Each patient should have a set of vaccines which can be modified.

Answer 1

Based on Mongo Blog for relationships best way of representing sql many to many is to keep relation ship array in the parent model (one-to-many approach with reference id) and use that array to for both way data joining.
