引用对象的猫鼬搜索属性

Question

我有两个对象

第一：

const Order = {
     orderNumber: String,
     deliveryInfo: [
          {
            type: Schema.Types.ObjectId,
            ref: 'Transit',
          },
        ],
     }

秒：

 const Transit = {
     order: {
          type: Schema.Types.ObjectId,
          ref: 'Order',
        }
 }

mongoose 中是否可以通过Transit 模型查询特定订单号？

类似的东西

const query = {}
query['order.orderNumber'] = '9999'

TransitModal.find(query)

由于某种原因，我没有得到任何结果。

如果查询变成如下形状

    query.order = {
      orderNumber: 1,
    };

出现以下错误

Answer 1

TransitModal.aggregate(
  [
    { "$lookup": {
      "from": ItemOrders.collection.name,
      "localField": "order",
      "foreignField": "_id",
      "as": "order"
    }},
    { "$unwind": "$order" },
    { "$match": { "order.orderNumber" : '9999' } } },
  ],
  function(err, result) {
    // do something
  }
)

Answer 2

试试这个：

TransitModal.find({}).populate('order').exec((err, transits) => {
  transits= transits.filter((transit) =>{
    return transit.order.orderNumber === '9999' ; 
  });
});
