Angular UI-Router $urlRouterProvider .when not working when I click <a ui-sref=“…”>

Question

I have .when('/center', '/center/question') in my angular web app.

When I type '/center' in my browser it will redirect to '/center/question' as I expect but when I click the <a ui-sref="center" href="#/center"></a> , it won't redirect and just stay on the url '/center' .

There is no error in my console and I don't know why.

I see one similar issue here Angular UI-Router $urlRouterProvider .when not working anymore .I try the answer but it still don't work for me.

Here is my coffeescript code:

whenConfig = ['$urlRouterProvider', ($urlRouterProvider) ->
  # default url config

  $urlRouterProvider
  .otherwise '/center'
  .when '/center', '/center/question'
]

stateConfig = ['$stateProvider', ($stateProvider) ->
  # nested url config

  capitalize = (s)->
    s[0].toUpperCase() + s[1..]

  mainConfig = ({
    name: name
    url: "/#{name}"
    templateUrl: "templates/#{name}.html"
    controller: "#{capitalize name}Ctrl"
  } for name in ['center', 'keywordList', 'keywordConfig', 'log', 'stat'])

  centerConfig = ({
    name: "center.#{name}"
    url: "/#{name}?page"
    templateUrl: "templates/center/#{name}.html"
    controller: "Center#{capitalize name}Ctrl"
  resolve:
    thead: (CenterService) ->
      CenterService.getThead @self.name
    data: (CenterService, $stateParams) ->
      CenterService.fetchItems @self.name, $stateParams.page
  } for name in ['question', 'answer', 'comment', 'article'])

  for singleConfig in mainConfig
    $stateProvider.state singleConfig

  for childConfig in centerConfig
    $stateProvider.state childConfig
]

app.config whenConfig
app.config stateConfig

Answer 1

There is a new working plunker (extending the Angular UI-Router $urlRouterProvider .when not working *anymore* ) , which should be working with the version 0.2.13+

Previous solution

Until version 0.2.12- we could use $urlRouterProvider.when() , suggested in documenation (small cite) :

How to: Set up a default/index child state

...
if you want the 'parent.index' url to be non-empty, then set up a redirect in your module.config using $urlRouterProvider:

 $urlRouterProvider.when('/home', '/home/index');

So this was solution shown in the Q & A mentioned above:

var whenConfig = ['$urlRouterProvider', function($urlRouterProvider) {

    $urlRouterProvider
      .when('/app/list', ['$state', 'myService', function ($state, myService) {
            $state.go('app.list.detail', {id: myService.Params.id});
    }])
    .otherwise('/app');
}];
...
app.config(whenConfig) 

Now - we cannot.

UI-Router "FIX" in 0.2.13

It is due to "FIX" (which I am simply not sure about) , mentioned in the release 0.2.13

Bug Fixes
$state:
- ...
- Avoid re-synchronizing from url after .transitionTo ( b267ecd3 , closes #1573 )

And here is the new code added in the urlRouter.js :

if (lastPushedUrl && $location.url() === lastPushedUrl)
 // this line stops the corrent .when to work
 return lastPushedUrl = undefined;

lastPushedUrl = undefined;

This piece of code is optimizing/fixing some other issue ... but also, turning off the .when() functionality

SOLUTION

As already mentioned, this brand new plunker shows the way with version 0.2.13+. We just have to listen to state change, and if the state is "app.list" we can go to its detail with some id...

var onChangeConfig = ['$rootScope', '$state',
 function ($rootScope, $state) {

  $rootScope.$on('$stateChangeStart', function (event, toState) {    
    if (toState.name === "app.list") { 
      event.preventDefault();
      $state.go('app.list.detail', {id: 2});
    }
  });

}]

Answer 2

You can do this in your controller too. I think it is cleaner than listening to state changes.

Example:

.controller 'YourControllerName', ($scope, $state) ->
    $state.go "center.question" if $state.is "center"
