node.js - 如何在 MongoDB 中引用集合内的文档

Question

帖子集合中的文档示例

{
    postId: '232323',
    byUser: 'userid1',
    post: 'This is my first post',
        commentsOnPost: [
            {
                commentId: '232323_8888',
                byUser: 'userid2',
            comment: 'Congrats',
                repliesOnPost: [
                    {
                        replyId: '232323_8888_66666',
                        byUser: 'userid1',
                    reply: 'Thanks',
                        likesOnReplyBy: ['userid1', 'userid5', 'userid3'],

                    },
                    {
                        replyId: '232323_8888_55555',
                        byUser: 'user2',
                    reply: 'Welcome',
                        likesOnReplyBy: ['userid6', 'userid8', 'userid9'],

                    }
                ]
            }
        ]
}

我想以这种方式查询这篇文章，以便无论用户标识来自哪里，我都想从匹配的用户标识集合中替换它。

[
 {
  userid:userid1,
  displayName:'Bob',
  profilePic:'https://example.com/bob_profile.png'
 },

 {
  userid:userid2,
  displayName:'Lorish',
  profilePic:'https://example.com/lorish_profile.png'
 }

.
.
.
.

]

这可能是这样的查询吗？或者我是否需要在插入文档时进行引用。我不想通过执行多次循环来一一替换用户标识。
