n.name = \"chat room\";
n.save(function(){
    //console.log(THE OBJECT ID that I just saved);
});

I want to console.log the ob

Answer 1

Mongo sends the complete document as a callbackobject so you can simply get it from there only.

for example

n.save(function(err,room){
  var newRoomId = room._id;
  });

Answer 2

you can get objectid in mongoosejs after you new some model.

i'm using this code work in mongoose 4, you can try it in other version

var n = new Chat();
var _id = n._id;

or

n.save((function (_id) {
  return function () {
    console.log(_id);
    // your save callback code in here
  };
})(n._id));
