Angularjs $resource not working with an array returned from a REST API

I am trying to learn angularjs, and have hit a block in trying to databind to an array returned from a Rest API. I have a simple azure api returning an array of person objects. Service url is http://testv1.cloudapp.net/test.svc/persons.

My controller code looks like:

angular.module("ToDoApp", ["ngResource"]);
function TodoCtrl($scope, $resource) {
$scope.svc = $resource('http://testv1.cloudapp.net/test.svc/persons', {
    callback: 'JSON_CALLBACK'
}, {
    get: {
        method: 'JSONP',
        isArray: true
    }
});
$scope.items = $scope.svc.get();
$scope.msg = "Hello World";
}

My html looks like:

<html>
<head></head>
<body>
<div ng-app="ToDoApp">
    <div ng-controller="TodoCtrl">
         <h1>{{msg}}</h1>

        <table class="table table-striped table-condensed table-hover">
            <thead>
                <th>Email</th>
                <th>First Name</th>
                <th>Last Name</th>
            </thead>
            <tbody>
                <tr ng-repeat="item in items">
                    <td>{{item.Email}}</td>
                    <td>{{item.FirstName}}</td>
                    <td>{{item.LastName}}</td>
                </tr>
            </tbody>
        </table>
    </div>
</div>
</body>
</html>

Question: The table in above html is not displaying any data. I can see the call to the api in Firebug, and can also see the JSON response from the api. What am I doing incorrectly that is causing the databinding to the REST api not work?

PS:JSFiddle demonstrating this issue is at: http://jsfiddle.net/jbliss1234/FBLFK/4/

In order to handle arrays with the $resource service, it's suggested that you use the query method. As you can see below, the query method is built to handle arrays.

{ 'get':    {method:'GET'},
  'save':   {method:'POST'},
  'query':  {method:'GET', isArray:true},
  'remove': {method:'DELETE'},
  'delete': {method:'DELETE'} };

The code you should use in order to return this array to your scope is

angular.module("ToDoApp", ["ngResource"]);

function TodoCtrl($scope, $resource) {
    var svc = $resource('http://testv1.cloudapp.net/test.svc/persons');
    $scope.items = svc.query();
    $scope.msg = "Hello World";
}

This assumes that your REST API is working and will return an array.

For further reading head to the docs

http://docs.angularjs.org/api/ngResource.$resource

Just wanted to cross-post my adaptation of a solution Aleksander gave on another stackoverflow question: http://stackoverflow.com/a/16387288/626810:

methodName: {method:'GET', url: "/some/location/returning/array", transformResponse: function (data) {return {list: angular.fromJson(data)} }}

So when I call this function:

var tempData = ResourceName.methodName(function(){
  console.log(tempData.list); // list will be the array in the expected format
});

Obviously this a little bulky if you need to GET arrays in multiple methods / resources, but it seems to work.

Use isArray param, if you have nested objects:

angular.module('privilegeService', ['ngResource']).
factory('Privilege', function ($resource) {
    return $resource('api/users/:userId/privileges', 
                     {userId: '@id'}, 
                     {'query':  {method:'GET', isArray:false}});
});

Than you can use container.object.property notation to access objects and its properties.

Not sure if we are having the same problem with json and REST, but this post solved my problem: array of strings not rendered correctly through angular resource

The array you get back from the server isn't a clean array, but has some extra properties. That makes ng-repeat not show anything when you iterate over it using in.

You need a special iterator to go over the array from the server, which will ignore those extra properties. So extract the array data through forEach first, like this:

$scope.items = []
var response = $scope.svc.get();
angular.forEach(response, function(item) {
  $scope.items.push(item);
});

Then you can do

<tr ng-repeat="item in items">

I don't see any response from http://testv1.cloudapp.net/test.svc/persons Are you sure that the response is in JSONP, but not in regular JSON format? May be you need to add callback to the REST service.
