Getting the value of a $resource call in AngularJS controller

Question

I'm using AngularJS and I've made a $resource call to fetch a single value (e.g. the fetch gets me 14).

The following is in my controller:

var MaxCount = $resource('/maxquestion/fetch', null, 
{
    getMaxQuestionCount: {method: 'GET', isArray: false}
});
$scope.maxQuestionCount = MaxCount.getMaxQuestionCount();

Now I'm trying to use $scope.maxQuestionCount in the controller, doing $scope.maxQuestionCount[0] gives me 1 and $scope.maxQuestionCount[1] gives me 4

console.log($scope.maxQuestionCount) me [object Object] console.dir($scope.maxQuestionCount) me There are no child objects

I'm confused. How to access the value 14?

There is really not much point in using $resource for data structures like those. The thing is that $resource works great for RESTful endpoint where all the HTTP verbs are used. To make this easy AngualarJS extends incoming objects with convenience methods ($save, $delete etc.). If you return primitives there is no room for extension and one of the major benefits of $resource is gone.

In short: if you are just after fetching data $resource is an overkill IMO, stick with the $http instead. The $http service, although considered to be lower-level as compared to $resource is very convenient and easy to use. Taking your example, you could write:

$http.get('/maxquestion/fetch').success(function(result){
  console.log(result);
});

Refer to the documentation for more examples: http://docs.angularjs.org/api/ng.$http

Thanks for the comment. I'll surely take that into consideration and rewrite the code I've written. Thanks for the heads up.

Thanks a lot! Really appreciate it. I've changed it to $http and it works now. Awesome
