.module("blog", ['firebase'])
// .controller("SampleCtrl", function($scope, $firebaseArray) {
// var ref = new Firebase("https://eventables.firebaseio.com/blog");
// var syncBlog = $firebaseObject(ref);
// syncBlog.$bindTo($scope, "data");
// })
.controller("BlogCtrl", function($scope, $firebaseArray) {
console.log("i rock oOO");
var ref = new Firebase("https://eventables.firebaseio.com/blog");
// create a synchronized array
$scope.blogPosts = $firebaseArray(ref);
// add new items to the array
// the message is automatically added to our Firebase database!
$scope.addPost = function() {
$scope.blogPosts.$add({
postTitle: $scope.newPostTitle,
postContent: $scope.newPostContent,
createdOn: Date.now(),
comments: [],
