I'm absolutely obsessed with it: Error - unable to switch to an abstract state

Hey there! Currently, I'm working on an app using the IONIC Framework and running into some issues with user validation errors. Below, you'll find a snippet of the logic I've implemented:

app.js:

angular.module('skulApp', ['ionic', 'ionic-material', 'ionMdInput', 'ngCordova'])
.run(function($ionicPlatform, $rootScope, $state, AUTH_EVENTS, _Auth_Service, sqliteService){

$ionicPlatform.ready(function(){
if (window.cordova && window.cordova.plugins.Keyboard)
        cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

    if (window.StatusBar)
        StatusBar.styleDefault();

    sqliteService.preloadDataBase(true);
});

$rootScope.$on('$stateChangeStart', function(event, next, nextParams, fromState) {
    if ('data' in next && 'authorizedRoles' in next.data) {
        var authorizedRoles = next.data.authorizedRoles;
        if (!_Auth_Service.isAuthorized(authorizedRoles)) {
            event.preventDefault();
            $state.go($state.current, nextParams, {reload: true});
            $rootScope.$broadcast(AUTH_EVENTS.notAuthorized);
        }
    }

    if (!_Auth_Service.isAuthenticated()) {
        if (next.name !== 'login') {
            event.preventDefault();
            $state.go('login');
        }
    }
});
})

app.config.js:

.config(function($stateProvider, $urlRouterProvider, $ionicConfigProvider, USER_ROLES) {

$stateProvider
.state('main', {
    url: '/',
    abstract: true,
    templateUrl: 'templates/main.html'
})

.state('login', {
    url: '/login',
    templateUrl: 'templates/login.html',
    controller: 'LoginCtrl'
})

.state('main.dashboard', {
    url: 'main/dashboard',
    views: {
        'menuContent': {
            templateUrl: 'templates/dashboard.html',
            controller: 'DashboardCtrl'
        },
        'fabContent': {
            template: '<button id="fab-profile" class="button button-fab button-fab-bottom-right button-energized-900" ui-sref="main.edit"><i class="icon ion-edit"></i></button>',
            controller: function($timeout) {
                $timeout(function() {
                    document.getElementById('fab-profile').classList.toggle('on');
                }, 800);
            }
        }
    },
    data: {
        authorizedRoles: [
            USER_ROLES.admin, 
            USER_ROLES.teacher, 
            USER_ROLES.father
        ]
    }
})

.state('main.edit', {
    url: 'main/edit',
    views: {
        'menuContent': {
            templateUrl: 'templates/edit.html',
            controller: 'EditCtrl'
        },
        'fabContent': {
            template: ''
        }
    }
    });

    $urlRouterProvider.otherwise(function($injector, $location){
        var $state = $injector.get("$state");
        $state.go('main.dashboard');
    });
    });

The error that's popping up is:

Error: Cannot transition to abstract state '[object Object]'
    at Object.transitionTo (ionic.bundle.js:40332)
    at Object.go (ionic.bundle.js:40262)
    at app.js:52
    at Scope.$broadcast (ionic.bundle.js:23003)
    at Object.transitionTo (ionic.bundle.js:40395)
    at Object.go (ionic.bundle.js:40262)
    at app.config.js:210
    at check (ionic.bundle.js:39247)
    at update (ionic.bundle.js:39259)
    at Scope.$broadcast (ionic.bundle.js:23003)

The specific line causing trouble in app.js is:

$state.go($state.current, nextParams, {reload: true});

Note that I haven't included services, constants, controllers, policies, etc., but if you feel like it's necessary, please let me know and I'll update the question accordingly. Any help would be greatly appreciated!

Answer №1

I believe the issue lies with your implementation of the $stateChangeStart function.

If certain conditions are met within the initial if statements, the following line may disrupt the intended route to /main/dashboard:

$state.go($state.current, nextParams, {reload: true});

This could potentially keep the state at the root level /.

Answer №2

When you open your browser on '/', the only state that matches is the abstract one. If no match is found, it doesn't get executed.

To redirect to your dashboard, use this instead of otherwise:

$urlRouterProvider.when('/', '/main/dashboard');
