AngularJS: Exploring the Power of Restangular Library

Currently, I am exploring the wonderful Restangular library and encountering an issue while attempting to fetch JSON objects and bind them to the $scope object.

Within my Factory script, I have a function that returns a list of blogs using the Restangular.getList() method.

angular.module("ecmaworld").factory("Authenticate", function(Restangular) {
// Testing Function
var Blogs = Restangular.all("blogs");
return {
    blogs: function() {
        Blogs.getList().then(function(blogs) {
            return blogs;
        }, function(error) {
            console.log(error);
        });
    }
};});

The above Factory method is responsible for returning the blog posts. To utilize this function in one of my controller scripts, I call it like so:

angular.module("ecmaworld").controller("LoginController", function($scope, Authenticate) {

//Testing function
$scope.getBlogs = function() {
    $scope.blogs = Authenticate.blogs();
};
});

Despite receiving the JSON objects in the http response when invoking the API method, I face difficulty in displaying the blog posts using the "data-ng-repeat" directive in the VIEW section. I would greatly appreciate any assistance as I navigate through this Angular learning curve.

Thank you.

The function retrieveBlogs() should respond with a promise...

retrieveBlogs: function() {
    return BlogPosts.fetchList("blogs").then(function(blogs) {
        return blogs;
    }, function(error) {
        console.log(error);
    });
}

After that, store the result in the scope property once the promise is fulfilled...

$scope.loadBlogs = function() {
    fetchContent.retrieveBlogs().then(function (blogs) {
        $scope.blogs = blogs;
    });
};
