Update array with multiple conditions in mongodb

Question

I have this document:

{
    \"_id\" : ObjectId(\"5b673f525ef92ec6ef16504e\"),
    \"events\" : [ 
        {
            \"name\" : \"Winner\",
            \"         


        

Answer 1

When there are multiple conditions to match inside an array then the .Dot notation doesn't work with update query.

You need to use $elemMatch to match exact two fields inside an array

db.getCollection('test').updateOne(
  {
    "_id": ObjectId("5b673f525ef92ec6ef16504e"),
    "events": { "$elemMatch": { "name": "Winner", "map": 2 }}
  },
  {
    "$push": { "events.$.something": { "something": "test" }}
  }
)
