I want to change library for database from github.com/mongodb/mongo-go-driver/mongo to github.com/globalsign/mgo, my problem is I dont know how convert this code for new library :

import "github.com/mongodb/mongo-go-driver/mongo/options"
res, err := s.totals().UpdateOne(ctx,
 bson.M"contract_id": cID, "date": date,
 bson.M"$inc": bson.M"value": value,
 options.Update().SetUpsert(true),
 )

My current code :

collection := s.totals()
err := collection.Update(
 bson.M"contract_id": contractID, "date": date,
 bson.M"$inc": bson.M"value": value,
 //options.Update().SetUpsert(true),
)

How i can convert this options.Update().SetUpsert(true) for use in new library ?

  Mgo is deprecated. The MongoDB "official" Go driver was created due to that project being abandoned.

  I would carefully consider using a fork, of a fork, of a fork, of an unmaintained project.

  @JimB The official MongoDB Go driver is still in a pre-release state, although it's getting close to a stable 1.0.

Simply use the Collection.Upsert() method instead of Collection.Update():

info, err := collection.Upsert(
 bson.M"contract_id": contractID, "date": date,
 bson.M"$inc": bson.M"value": value,
)

Quoting from the doc of Collection.Upsert():

Upsert finds a single document matching the provided selector document and modifies it according to the update document. If no document matching the selector is found, the update document is applied to the selector document and the result is inserted in the collection.
