Mongoose retrieving data without _id field

Question

I would like to retrieve some data from a Mongoose setting in my Node.js application. I noticed that no matter what I write as field selection, I always get the _id

Answer 1

_id must be specifically excluded. For example,

Transaction.find({username : user.username}, { '_id': 0, 'uniqueId' :1, 'timeout': 1, 'confirmation_link': 1, 'item_name': 1}, function(err, txs){
  console.log("user : " + user.username + " with txs: " + txs);
  callback(txs);
});
