Update deeply nested array in mongodb

Question

I am trying to update field value in mongoose.

{
    \"_id\" : ObjectId(\"5b62c772efedb6bd3f0c983a\"),
    \"projectID\" : ObjectId(\"0000000050e62416d0d758         


        

Answer 1

You can try with arrayFilters in mongodb

var mongoose = require('mongoose')


Temp.update(
  { "_id" : mongoose.Types.ObjectId("5b62c772efedb6bd3f0c983a") },
  { "$set": {
    "inspection_data.$[e1].locationAspects.$[e2].comments.$[e3].images.$[e4].title": "TableFan"
  }},
  { "arrayFilters": [
    { "e1._id": mongoose.Types.ObjectId("5b62c772fa02622a18655e7b") },
    { "e2._id": mongoose.Types.ObjectId("5b62c772fa02622a18655e80") },
    { "e3._id": mongoose.Types.ObjectId("5b62c772fa02622a18655e81") },
    { "e4.id": "1" }
  ]}
)

Note: You have to cast _id to ObjectId
