grab followers from mongoose schema - angularjs

Question

Basically I have a User schema. Within the schema I have the following item which contains the id's of all users. The user follows inside an array.
followers: [{
type: String,
required: false,
unique: false
}],
My question is: how do I get all the results from the followers array only so I can run a ng-repeat with them?
This is what I have tried.
Get Followers controller:
(function(){
angular.module('Scrimbox')
.controller('GetFollowingController'
, ['$scope', '$http', 'User', '$routeParams', '$location'
, function( $scope, $http, User, $routeParams, $location){
$scope.following = function(){
//Empty object to send to server
var request = {};
//get follower id
var FollowerId = $routeParams.id;
//bundle into the object to send to server
var request = {
follower: FollowerId
};
//send to server
$http.post('api/social/getfollowing', request)
.success(function(response){
console.log(response);
$scope.following = response.following;
}).error(function(error){
console.log(error);
});
};
$scope.following();
}]);
}());
getfollowing on the server:
var mongoose = require('mongoose');
var User = require('../../models/UserModel');
module.exports.getfollowing = function(req, res){
var thefollower = req.body.follower;
User.findOne({ _id: thefollower }).populate('_following').exec(function (err, user) {
if (err) {
console.log(err);
res.json(err);
} else {
console.log(user);
res.jsonp(user);
}
})
};
Called using:
app.post('/api/social/getfollowing', getfollowingController.getfollowing);
This is the response I get from the server:
But how do I only get all the ids from the following array?
Then how do I use them for a ng-repeat?

Answer 1

ok i did get this thanks for the responses.
i had to query the mongoDB for the user then create a variable for the followee's ID's then run a forEach Loop over all the IDs
var mongoose = require('mongoose'),
User = require('../../models/UserModel'),
async = require('async');
module.exports.getfollowing = function(req, res){
//grab the Users ID from the body
var thefollower = req.body.follower;
//create empty array that i want to populate with the followee's ID and Avatar url
var obj = [];
//query mongo for the user
User.findOne({ _id: thefollower }, function (err, user) {
if (err) {
console.log(err);
res.json(err);
} else {
//grab the following element of the users mongo schema -- should return all the followee's ID's -- tested works
var following = user.following;
//iritate throught all the followee's
async.forEach(following, function(item, callback) {
//current followee
var user = item;
//query mongo for the followee
User.findOne({_id: user}, function(err, followee, callback){
//get followee's ID and Avatar url
var id = followee._id;
var avatar = followee.avatar;
//add the followee's ID and Avatar url to the obj array
obj.push({
id: id,
avatar: avatar
});
});
//see if this worked - returns empty
console.log(obj);
callback();
}, function(err) {
//see if this worked - returns empty
console.log(obj);
//respond to the client - returns empty
res.json(obj);
});
}
});
};
