.updateOne on MongoDB not working in Node.js

Question

I have the following code:

connection((db) => {
            db.collection(\'orders\')
                .updateOne(
                    { \"_id\": req.body         


        

Answer 1

Tough @Spraw's answer is right for some cases, but sometimes it doesn't work. I think the convenient answer is updateOne({_id: new ObjectID(req.body._id)}, {$set: {"name": req.body.name}}, callback).

the _id in mongodb is a BSON object and should be instantiated.

Answer 2

This might happen if the collection schema is missing the field that is to be updated. If the schema is not strict (i.e, isStrict: false), check the update operator. In some cases, the new update value can be same as existing value. In this case, mongoose returns

{ n: 1, nModified: 0, ok: 1 }
