How to remove _ID from results?

[ekanna]

Hi all,

Is there any easy way to remove the _ID from results?

Thanks koti

At present i am using below functions to remove _ID from the retrieved array:

function myArr (arr){
var x = arr.length; var z = []; for(var y=0; y<x; y++){ z[y] = myObj(arr[y]); }
return z; }

function myObj (obj){
var s = Object.keys(obj).slice(1); var i = 0; var j = s.length; var o = {}; for (i=0; i<j; i++){ o[s[i]] = obj[s[i]]; }
return o; }

But looking for a better way todo this. As it may not the optimal way to do. I am looking for some in built options available in Mongous to remove _ID from the result array.

Oh my! This is a javascript issue. I am very pleased to tell you that you can delete any property/attribute from any object in javascript simply by...

var obj = { hello: "world", nice: "to see you" }; delete obj.nice;

And now the object is

{hello:"world"}

So all you have to do is:

delete obj['_id'];

fyi. I don't like _id either, but it is how Mongo keeps tabs on things - go read MongoDB's documentation on IDs for more information. Also, this was a javascript question, not an issue with mongous (or MongoDB) - so please make sure you ask any next questions in the appropriate location.

Enjoy Mongous!
