Question

I ve got a collection users that look like this :

{
_id: myid,
name : 'blabla',
ia : {
       [0]-> 'an id',
       [1]-> 'a second id'
      }
}

And i want to have only my first id of ia, so i tried something like that :

User.find({ _id: id, ia :{ key : indexia} }, ['ia']).populate('ia').run(rendu);

where id= myid, and indexia=0.

If i don t put that part : ” ia :{ key : indexia}” i get all my ia… but i want only one.

Hope i was clear.
Thanks

Thanks for your help
It worker like that:

User.find({ _id: id }).only('ia').slice('ia', indexia, 1).populate('ia').run(rendu);

The only(‘ia’) don t work, but not a big deal.
