Setting a child or grandchild state as the default index state using ui-router: A step-by-step guide

My current project involves using Angular with ui-router. I'm looking to achieve a specific functionality where various links, such as:

/
/contacts
/contacts/:id

should all display the same content as the link /contacts/:id, but with a default :id parameter. Additionally, I want the URL to remain unchanged and not switch to /contacts/:id.

While there is documentation on the ui-router wiki that addresses this issue, it does not provide a demo for initializing grandchild or deeper descendant states.

How to: Set up a default/index child state

I've experimented with different state settings without success. Could it be that I am implementing it incorrectly? Feel free to take a look at my sample page:

Answer №1

Resolved this issue using the .when() method. Check out an example at: ui-router-test.

$urlRouterProvider
    .when('/', ['$state', function ($state) {
        $state.transitionTo('contacts.detail', {contactId: 1}, {location: false});
    }])
    .when('/contacts', ['$state', function ($state) {
        $state.transitionTo('contacts.detail', {contactId: 1}, {location: false});
    }])
    .otherwise('/');

$stateProvider
.state("home", {
    url: "/"
})
.state('contacts', {
    url: '/contacts',
    template: 'Contacts: <div ui-view></div>'
})
.state('contacts.detail', {
    url: '/:contactId',
    template: '<p class="lead">Contact ID is {{$stateParams.contactId}}</p>'
});
