MongoDB：嵌套数组更新问题

Question

我正在使用平均堆栈在网格中显示以下数组。

嵌套数组：

{  
   "_id":"1",
   "appDomain":[  
      {  
         "appDomainName":"XYZ",
         "dashboard":[

经过长时间的挣扎，我想通了。请看下面的答案。

    var data2 = {};
     AppDomain.update(
      {_id:1,'appDomain.appDomainName':  req.params.appDomainName,'dashboard.$.envName':{$nin:[req.params.envName]}},
            {$push: {'appDomain.$.dashboard.0.envDetails':{'envDetails':[data2]}}},
            function(err, model) {
                console.log(err);
            }
        );
