How to update a nested object in array that is in the array of object in mongoose-CodePudding

I have Locations collection in MongoDB that includes two documents. Each one of them has it's own array of confirmed bookings as objects with Ids. How can I update the object that has _id: c1? Is it possible to do that in a single query?


[{
_id :63233022222222,
title :"Ravenholm",
price: 180,
capacity: 2,
confirmedBookings: [
 {
  _id : r1,
  start: 1663207200000,
  finish: 1663210799999
 },
 {
  _id: r2,
  start: 1663322400000,
  finish: 1663329599999
 }
]
},
{
_id :6323301111111111,
title :"City 17",
price: 360,
capacity: 4,
confirmedBookings: [
 {
  _id : c1,
  start: 1663207200000,
  finish: 1663210799999
 },
 {
  _id: c2,
  start: 1663322400000,
  finish: 1663329599999
 }
]
}]

You can use elemMatch to find the element inside array, then update it's value.

return await documentName.findOneAndUpdate({ confirmedBookings: { $elemMatch: { _id: "c1"} } }, {"confirmedBookings.$._id" : newValue})

Write your schema's name to documentName.

Also, write your value to search as $elemMatch: {_id: "c1"} . The newValue is the new value you want to update.

I hope, this helps you. Good luck.

You should be able to query and update the specific object with:

const updated = await Model.findOneAndUpdate(
  { 'confirmedBookings._id': c1 },
  {
    'confirmedBookings.$.start': 'new-start',
    'confirmedBookings.$.finish': 'new-finish',
  },
  { new: true }
);
