Mongoose：查找和更新多个嵌套文档

Question

My Documents are as follows.

{
    "order_id" : "1",
    "payment_status" : false,
    "items" : [
        {
            "item_id" : 1,
            "payment_status" : false,
        },
        {
            "item_id" : 2,
            "payment_status" : false,
        },
        {
            "item_id" : 3,
            "payment_status" : false,
        },
    ]
}

I need to update the fields payment_status for {"order_id":1} and {"item_id" : 1} and {"item_id" : 3} . Also, I need to update the same in bulk for matching conditions. Is this possible in mongoose?

You want to be using $arrayFilters like so:

db.collection.updateMany({
  "order_id": "1"
},
{
  "$set": {
    "items.$[item].payment_status": true
  }
},
{
  arrayFilters: [
    {
      "item.item_id": {
        $in: [
          1,
          3
        ]
      }
    }
  ]
})
