如何在 MongoDB 中引用集合内的文档

如何解决如何在 MongoDB 中引用集合内的文档

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',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 ID 出现在哪里，我都想从匹配的用户 ID 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？或者我需要在插入文档时做参考吗？ 我不想通过执行多次循环来一一替换 userid。

预期产出
