Mongodb Update Multiple Document, Insert if not Exist

Question

If upsert:true is set then mongodb insert new document if exist. My below query working fine for single document. Unique Index:- {fid:1,uniqueid:1,atype:1,ftype:1}

db.Notification.updateMany(
  {fid : 103,uniqueid:1001,atype:1,ftype:6}
  ,{ $set: { epoch: 1548484978658,actionbyuserid: 110, title: 'Good Morning To All'}}
  ,{upsert:true}
);

But when execute below query it is not inserting new documents for not matched documents;

db.Notification.updateMany(
 {fid : {$in:[101,102,103]},uniqueid:1001,atype:1,ftype:6}
  ,{ $set: { epoch: 1548484978658,actionbyuserid: 110, title: 'Good Morning To All'}}
,{upsert:true}
)

Is there other to check and insert not found documents ?

Answer 1

You can use bulkWrite operation

Array you want to update with

const array = [101, 102, 103]

Query for bulk update

Model.bulkWrite(
  array.map((val) => 
    ({
      updateOne: {
        filter: { _id: val, uniqueid: 1001, atype: 1, ftype: 6 },
        update: { $set: { epoch: 1548484978658, actionbyuserid: 110, title: 'Good Morning To All'} },
        upsert: true
      }
    })
  )
})
