Replace a Document

Example

The following example performs the following on the haikus collection:

• Matches a document in which the title is "Record of a Shriveled Datum"

• Replaces the matched document with a new document

coll := client.Database("insertDB").Collection("haikus")
filter := bson.D{{"title", "Record of a Shriveled Datum"}}
replacement := bson.D{{"title", "Dodging Greys"}, {"text", "When there're no matches, no longer need to panic. You can use upsert"}}
result, err := coll.ReplaceOne(context.TODO(), filter, replacement)
if err != nil {
	panic(err)
}
