我有一个名为＆＃34;用户＆＃34;的模型。这个JSON是用户之一。好的，所以＆＃34;三＆＃34;中的对象他们自己的模型称为＆＃34; Time＆＃34;。我想通过他们的id选择其中一个，然后更新它。我怎么能这样做？我正在使用猫鼬。显然，Time.findOne（）不起作用，因为该集合是＆＃34;用户＆＃34; 包含＆＃34;时间＆＃34;。

 yourUserModel.findById(userId, function(err,user) {  
          var i;
            if(err || user === null){
            return;
            }
           var stats = user.stats;

           for(i =0; i<stats.three.three.length; i=i+1) {
              if(stats.three[i]._id === yourId) { //id of object to be updated
                  stats.three[i].status = 1; //updating
    }

    }
user.stats = stats;
user.save();
            });
