Aggregation in Golang mgo for Mongodb

Question

Anybody knows what’s the equivalent of aggregate command we use in mongodb shell for golang mgo/bson?

Something like that:

aggregate([{$match:{my_id:Obje         


        

Answer 1

Assuming that c is your Collection:

pipe := c.Pipe([]bson.M{{"$match": bson.M{"name":"John"}}})
resp := []bson.M{}
err := pipe.All(&resp)
if err != nil {
  //handle error
}
fmt.Println(resp) // simple print proving it's working
