possible to get updated/created doc on upsert?

[ralyodio]

I was expecting the 2nd argument to the callback to be the newly created or updated doc, but there is no 2nd argument:

I'm coming from nedb which supposedly has same API so this is probably wrong:

db.things.update({ hash: data.hash }, data, { upsert: true })
    .then((err, numReplaced, doc) => {
      if (numReplaced) {
        return console.log('replaced %s docs', numReplaced);
      }

         // how do i get num of docs updated and also the new docs?
      console.log(doc);
    })
    .catch(err => {
      return console.error(err, data);
    });

But I want to get number of docs replaced (if upserted) and also the new doc regardless of update or insert happened.

Any updates on this?

First as you use promises and mongojs does not support promises out of the box I guess you opened this issue in the wrong repository (did you mean the official mongodb driver?)

Mongodb does not support getting (updated, upserted) documents as a result of the update operation but returns a WriteResult (https://docs.mongodb.com/manual/reference/method/db.collection.update/)

The write result you'll receive in a callback as second argument looks somehow like this { n: 1, nModified: 0, upserted: [ { index: 0, _id: abeabeabeabeabeabeabeabe } ], ok: 1 }

You can use the _id value of the upserted array to query the documents after updating the db.
