MongoDB：查找数组中对象的查询

Question

我的目标是使用我的node.js服务器查询mongodb，以便获取所有尊重模式中数组中约束的对象。

这是我的架构

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var config = require('../../config.js');

module.exports = mongoose.model(config.DATA_TYPE.ROOM, new Schema({
    name: String,
    guide: String,
    leader: String,
    partecipants_counter : { type: Number, default: 0},
    event_counter : { type: Number, default: 0},
    creation: { type: Date, default: Date.now},
    partecipants: [],
    events : [ {
            id : Number,
            data: String,
            user: String
            } ]
}));

我想做一个像：

这样的查询

SELECT events FROM room WHERE events.id > myInput

我开始编写查询但缺少events.id > lastEventId条件：

getLastEventsById: function(roomId,lastEventId,callback){
        Room.findById(roomId,{name: 0, __v: 0, guide: 0, leader: 0, creation: 0, partecipants_counter: 0, partecipants: 0},callback);
    }

只是为了更好的理解，这就是它现在的工作方式我的代码（我想删除我的for循环）：

getLastEventsFromId: function(roomId,lastEventId,callback){
        this.getAllEvents(roomId,function(err,data){
                var events_to_send = [];
                for(var i = lastEventId ; i < data.event_counter; i++) events_to_send.push(data.events[i]);
                callback(err,events_to_send);
        });
    },
getAllEvents: function(roomId,callback){
        Room.findById(roomId,{name: 0, __v: 0, guide: 0, leader: 0, creation: 0, partecipants_counter: 0, partecipants: 0},callback);
    }
