如何在两个集合之间创建关系

Question

我有两个猫鼬模型：user.js和note.js，以及两个集合notes和users。用户将能够保存他们的笔记。我不知道如何在藏品之间建立关系。我希望能够识别笔记和创建笔记的用户，我应该如何做到这一点？

const userSchema = new Schema(
{
username: {
type: String,
required: [true, "Please enter a username"],
unique: true,
},
password: {
type: String,
required: [true, "Please enter a password"],
minLength: [8, "The minimum password length is 8"],
},
},
{ timestamps: true }
);

note.js

const noteSchema = new Schema({
title: {
type: String,
},
text: {
type: String,
},
});
