如何更新MongoDB中

Question

一个数组的多个项目，这是我的文档模式：

{ 
     "_id": "599345434a6caf2d9d2e2b67", 
     "total": 870, 
     "product_info": [ 
      { 
       "product_id": "597de6e76dbf1a0004b98eb5", 
       "mrp": 20, 
       "quantity": 1, 
       "name": "bottle", 
       "product_status": 1 
      }, 
      {

       "quantity": 1, 
       "name": "all out", 
       "product_status": 1 
      }, 
      { 
       "product_id": "597deb196dbf1a0004b98ebd", 
       "mrp": 150, 
       "quantity": 1, 
       "name": "neem extract",

      } 
     ],

     "address_id": "NA", 
     "payment_type": 1, 
     "address_type": 1, 
     "start_date": "2017-08-15T18:53:38.976Z", 
     "last_update_date": "2017-08-15T19:02:27.245Z", 
     "order_status": 1, 
     "delivery_status": 1, 
     "payment_status": 1, 
     "delivery_date": "NA", 
     "payment_date": "NA" 
    } 

我的查询

我会送的product_id我需要更新和product_status的名单列表，我需要改变为如

var product_ids=["597de6e76dbf1a0004b98eb5","597dea7d6dbf1a0004b98ebb"]; 
var product_status=[2,3]; 

所以，我怎么可以更新的内部产品的详细信息，其ID在product_ids阵列中的所有产品只是product_status。

Answer 1

这应该为你工作：

var bhupendra = localdb.collection('bhupendra'); 

var product_ids=["597de6e76dbf1a0004b98eb5","597dea7d6dbf1a0004b98ebb"]; 
var product_status=[2,3]; 

for (var i = 0; i < product_ids.length; i++) { 
    bhupendra.update({_id: "599345434a6caf2d9d2e2b67", "product_info.product_id": product_ids[i]}, { $set: { "product_info.$.product_status" : product_status[i] } }); 
}
