var app = angular.module("app", ["ngRoute"]);

app.config(function ($routeProvider) {
    $routeProvider
        .when('/',
        {
            templateUrl: "app.html",
            controller: "ViewCtrl",
            resolve: {
                loadData: viewCtrl.loadData
            }
        })
});

app.controller("AppCtrl", function ($rootScope) {
    //event on route, depends on root scope
    $rootScope.$on("$routeChangeError", function (event, current, previous, rejection) {
        console.log(event);
        console.log(current);
        console.log(previous);
        console.log(rejection);
    })
});

var viewCtrl = app.controller("ViewCtrl", function ($scope, $route) {
    console.log($route);
    $scope.model = {
        message: "I'm a great app!"
    }
});

viewCtrl.loadData = function ($q, $timeout) {
    var defer = $q.defer();
    $timeout(function () {
        defer.reject("Your network is down");
    }, 500);
    return defer.promise;
