How to create compund index with mgo

[melvin davis]

Hi,

I have something like this :- 

UsersDocument= mgo.Index{

  Key:        []string{"emailid", "purpose"},

  Unique:     true,

  DropDups:   true,

  Background: true,

  Sparse:     true,

}

But I want it to be compund index unique. How can I implement the same?

Thanks in advance...

I think this one has already generated a compound unique index.

index = mgo.Index{

Key:    []string{"xxx", "Name"},

Unique: true,

}

err = col.EnsureIndex(index)

Have you checked this on any mongo UI?
