I'm trying to get getObj() function will be more general and could work
with any type, not only User like in my code. I was thinking in return a
interface instead a defined struct, but I can't fit this idea to my code,
please could someone give me a hand with this?
Thanks in advance

type User struct {
     FirstName string `bson:"first_name"`
     LastName string `bson:"last_name"`}

type Mbase struct {
     coll *mgo.Collection
     sess *mgo.Session}

func (b *Mbase) getObj(attr string, val string) (res *User, err error) {
     err = b.coll.Find(bson.M{attr: val}).One(&res)
     if err != nil {
         return
     }
     err = nil
     return}

    Doesn't feel like the helper is doing much good, though. Find+One
    itself is already generic. I'd also consider using bson.D{{attr, val}}
    instead of bson.M if that's all you need.

    Hi Juan,

    I put together a simple package that you might find useful:
