I have a service to get User data. The returned data shall be used in a controller.

My problem is, that I can't access the data from db.find inside the getUsers() function.

Service

 app.service('userService', function(){

 this.getUsers = function() {

      var users;

     //neDB find all Users in DB
     db.find({}, function (err, data) {
       queryReturn(data);
     });

     function queryReturn(data) {
       console.log(JSON.stringify(data));
       return data;
     }
   };
});

Controller

app.controller("mainCtrl", function ($scope, userService) {

    $scope.users = '';
    $scope.users = userService.getUsers();
    console.log("Users " + $scope.users);

});

Can anyone give help out with this?

EDIT:

I changed the code in the Service and now I get all the data I want when calling getUsers(). BUT how can I access this data in my controller? It always returns: undefined..

need to return a promise in the getUsers method, its async – reptilicus Jan 20 '16 at 19:39
I don't see that db is declared anywhere. – Daniel Nalbach Jan 20 '16 at 19:40
You said Angular but you seem to be using mongo too, can you explain better what are you using? angular+meteor maybe? mean.io? – Javier Conde Jan 20 '16 at 19:44
I changed the Service and its working now within the Service. But how can I access the data in my controller? @DanielNalbach I left out the DB declation. This is not the problem. I use angular with neDB. – MarcJohnson Jan 21 '16 at 08:50
