Angular UI Router - Dynamic states get double slashes when navigated to with ui-sref

I'm creating a CMS system so I want the states to be dynamically created. Since you can't make http requests within the config phase I decided to add my routes in the .run() function as described here: http://blog.brunoscopelliti.com/how-to-defer-route-definition-in-an-angularjs-web-app

Now when I display a list of links in my navigation partial using the ui-sref directive the url that is appended has 2 forward slashes instead of one. The controller and everything is called accordingly but I can't seem to get rid of the double slashes. Any ideas?

Here is the relevant code:

app.js

var $stateProviderReference;

angular.module('app', [
    'ui.router',                // Angular UI Routing
    'ngStorage',                // Angular Storage (local, cookies, session)
    'ngAnimate',                // Angular Animation
    'angular-loading-bar',      // Angular Loading Bar
    'restangular',              // Restangular
    'angular.assets.injector',  // Custom assets injector
])
.config(function($stateProvider, $urlRouterProvider, RestangularProvider, $httpProvider, cfpLoadingBarProvider){

    // Save a reference of our stateProvider
    $stateProviderReference = $stateProvider;

    // Irrelevant configuration

    // States (routes)
    $stateProvider

        /*
         |
         | Frontend
         |
         */
        .state('frontend', {
            url: '/',
            views: {
                '': { 
                    templateUrl: 'app/views/frontend/templates/default/bootstrap.html',
                    controller: 'FrontendCtrl'
                },
                '[email protected]': {
                    templateUrl: 'app/views/frontend/templates/default/partials/navigation.html',
                    controller: 'NavCtrl',
                    resolve: {
                        pages: function(PageService){
                            return PageService.all();
                        }
                    }
                },
                '[email protected]': {
                    templateUrl: 'app/views/frontend/templates/default/partials/footer.html',
                    controller: 'FooterCtrl'
                },
                '[email protected]': {
                    templateUrl: 'app/views/frontend/pages/page.html',
                    controller: 'PageCtrl'
                }
            }
        });

.run(function($rootScope, $location, $state, $stateParams, AuthService, CSRF_TOKEN, PageService){

    // Retrieve all the pages
    PageService.all().then(function(pages){

    // Loop through all the pages
    angular.forEach(pages, function(page){

        // If this is not the homepage
        if( page.routeName !== 'frontend' )
        {
            // Add a state to our stateProvider
            $stateProviderReference.state(page.routeName, {
                // Set the desired url
                url: page.url,
                // Views that we are populating
                views: {
                    // Override the page view partial
                    '[email protected]': {
                        templateUrl: 'app/views/frontend/pages/page.html',
                        controller: 'PageCtrl'
                    }
                }
            });
        }

    });

});

navigation.html partial

<ul class="nav navbar-nav">
    <li ng-repeat="page in pages">
        <a ng-class="{'active': isActive({{page.routeName}})}" ui-sref="{{ page.routeName }}">{{ page.title }}</a>
    </li>
</ul>

Page data being retrieved from the db is formatted like this:

{
    id: 1,
    routeName 'frontend.home',
    title: 'Homepage',
    url: '/home',
    metaData: {
        tags: "some random tags",
        desc: "some random description"
    },
    content: "Html goes here",
    deletable: 'yes' // or 'no'
}

So everything seems to work except for the double slashes. When I click on the link generated for the above sample code it will send me to the following url:

http://localhost/CMSv2/public/#//home

instead of

http://localhost/CMSv2/public/#/home

I have tried removing the forward slash from the routeName property and then it does not append the double slashes but the controller can't be reached anymore and everything seems to break.

The issue comes from the fact, that if there are states parent - child their url is parent.url + child.url:

  • parent: .state('frontend', { url: '/',...
  • child: { routeName 'frontend.home', url: '/home',..
  • result: '/' + '/home' === '//home'

But again there is a nice solution built into the ui-router:

small cite:

If you want to have absolute url matching, then you need to prefix your url string with a special symbol '^'.

$stateProvider
  .state('contacts', {
     url: '/contacts',
     ...
  })
  .state('contacts.list', {
     url: '^/list',
     ...
  });

SOLUTION: (very easy in this case)

Instead of this url def:

{
    id: 1,
    routeName 'frontend.home',
    title: 'Homepage',
    url: '/home',
    ...

We just will path this url: '^/home',:

{
    id: 1,
    routeName 'frontend.home',
    title: 'Homepage',
    url: '^/home',
    ...
Answer

Since your home-state is derived from the frontend-state, the additional slash is added from the frontend-url. To remove the extra initial slash, set the frontend-state to "abstract" and clear the url like so:

.state('frontend', {
    abstract: true,
    url: '',
    templateUrl: 'yourTemplate.html'
})

This better corresponds to your structure as well, since the frontend-state url is never used.
