Mongoose overwrite the document rather that `$set` fields

Question

Say, i have a document:

{
  _id: \'some_mongodb_id\',
  name: \'john doe\',
  phone: \'+12345678901\',
}

I want to update this document:

Answer 1

You can pass upsert option, and it will replace document:

var collection = db.collection('test');
collection.findOneAndUpdate(
  {'_id': 'some_mongodb_id'},
  {name: 'Dan smith Only'},
  {upsert: true},
  function (err, doc) {
    console.log(doc);
  }
);

But the problem here - is that doc in callback is found document but not updated. Hence you need perform something like this:

var collection = db.collection('test');
collection.update(
  {'_id': 'some_mongodb_id'},
  {name: 'Dan smith Only'},
  {upsert: true},
  function (err, doc) {
    collection.findOne({'_id': 'some_mongodb_id'}, function (err, doc) {
        console.log(doc);
    });
  }
);
