ui-router nested states, basic understanding - angularjs

Question

I'm trying to create a nested state config. When I go with the simple non-nested it works, but when I attempt to do it in a nested fashion it fails.
Below is the working code: (Notice the last state 'new')
app.config(
function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/home',
templateUrl: '/views/home.html',
controller: 'MainCtrl',
resolve: {
qstnrPromise: ['qstnrs', function(qstnrs) {
return qstnrs.getAll();
}]
}
})
.state('questionnaires', {
url: '/questionnaires/{id}',
templateUrl: '/views/questionnaire.html',
controller: 'QuestionsCtrl',
resolve: {
questionnaire: ['$stateParams', 'qstnrs', function($stateParams, qstnrs){
return qstnrs.get($stateParams.id);
}]
}
})
.state('new', {
url: '/questionnaires/{id}/new',
template: '<h3> testy </h3>'
});
//$urlRouterProvider.otherwise('home');
$urlRouterProvider.otherwise(function($injector, $location){
$injector.invoke(['$state', function($state) {
$state.go('home');
}]);
});
});
If I attempt to change it with the following, it fails. The URL on browser changes but I don't receive the template.
.state('questionnaires.new', {
url: '/new',
template: '<h3>New question</h3>'
});
Have I understood states incorrectly? Or where have I gone wrong?

Answer 1

Try changing your new state to:
.state('new', {
url: '/new',
parent: 'questionnaires',
template: '<h3>New question</h3>'
})
See if that works for you.

Answer 2

You can make the questionnaires state abstract.
$stateProvider
.state('questionnaires', {
abstract: true,
url: '/questionnaires',
})
.state('questionnaires.new', {
// url will become '/questionnaires/new'
url: '/new'
//...more
})
But in this case you will need to add one additional nested state in order to implement the functionality you need for the $stateParams.id.
