The challenge in Angular ui-router is that although the nested state URL changes, the template fails to load

Currently, I am faced with an issue while using ui-router for nested states & views. Whenever I click on the link, the URL transitions to the substate URL correctly, but unfortunately, the associated template fails to load.

For instance, when the URL changes to the substate project/settings, the respective template project.settings.html does not seem to be loading as expected.

To demonstrate this problem, you can view the SSCCE provided through Plunkr

Below is the snippet of my code:

app.js

myApp.config(function ($stateProvider, $urlRouterProvider){
             $stateProvider
                  .state('project', {
                         url: "/project",
                         views:{
                         "content":{templateUrl: "partials/project.html"},
                         "header":{templateUrl: "partials/header"}
                         }
                       })

                  .state('project.settings', {
                          url: "/settings",
                          views:{
                           "content":{templateUrl: "partials/project.settings.html"},
                           "header":{templateUrl: "partials/header"}
                          }
                         }) 
            $urlRouterProvider.otherwise("/")                   
   }); 

    /* checking if the user is authenticated or not*/


 myApp.run(function($rootScope,$location,$cookieStore,validateCookie,$state) {
      $rootScope.$on('$stateChangeStart',function(event,toState,toParams,fromState){
         if($cookieStore.get('user')){
            validateCookie.authService(function(result,error){
              if(!result){
                 $location.path("/");
              }else{
                $state.go('project.settings');
              }
            });   
         }
         else{
            $location.path("/"); 
         }
        });
    });

index.html

                <div ng-controller="userController">
                    <div ui-view="header"></div>
                    <div class="container" ui-view="content"></div>
                </div>

project.html

            <div ng-controller="userController">
                <div class="details">
                    <a ui-sref=".settings" class="btn btn-primary">Settings</a>
                </div>
            </div>

project.settings.html

        <h1>Project Setting - State test</h1>

Answer №1

In order to properly utilize your nested project.settings state, you must specifically reference the view in the higher state by adding an '@' suffix, as shown below:

.state('project.settings', {
        url: "/settings",
        views:{
              "content@":{templateUrl: "partials/project.settings.html"},
              "header@":{templateUrl: "partials/header"}
        }
 }) 

To learn more details about this concept, please visit https://github.com/angular-ui/ui-router/wiki/Multiple-Named-Views#view-names---relative-vs-absolute-names

Answer №2

To begin, modify the file name project.settings.html in templateurl and change it to projectSettings.html (without the dot).

   .state('project.settings', {
         url: "/settings",
          views:{
               "content":{templateUrl: "partials/projectSettings.html"},
               "header":{templateUrl: "partials/header"}
           }
    }) 

Add two div elements in the project template to display the sub pages (header and projectSettings)

Please note: Any content within these divs will be replaced by the loaded page.

project.html

     <div ng-controller="userController">
        <div class="details">
            <a ui-sref=".settings" class="btn btn-primary">Settings</a>
        </div>
        <div ui-view="header">( Project Page header will be replaced with projectSettings header )</div>
        <div class="container" ui-view="content">( Project Page content will be replaced with projectSettings Content )</div>

    </div>

Answer №4

When implementing nested views with UI-router, don't forget to insert the ui-view tag in the parent page's HTML and define unique named views for each one.

Answer №5

I encountered a similar issue and found a solution; simply open the project.html file (the parent page) and surround everything within <ui-view>

Here's what needs to be replaced:

<div ng-controller="userController">
  <div class="details">
    <a ui-sref=".settings" class="btn btn-primary">Settings</a>
  </div>
</div>

Replace it with this:

<ui-view>
 <div ng-controller="userController">
   <div class="details">
     <a ui-sref=".settings" class="btn btn-primary">Settings</a>
   </div>
 </div>
</ui-view>

Once you make this change, everything should work smoothly ;)

Answer №6

Incorporate the ui-sref="project.settings" syntax to create a hyperlink within the project.html file.
