edit: Based on the answer by #actor2019 I want to update my question to better explain the problem:
Using Angular UI-Router(v0.0.2), I've setup the app to properly navigate between main "pages"/state, while inheriting the base state.
Index.html:
<div ui-view></div>
base.html:
<!-- Header -->
<div>
<!-- Header markup -->
<!-- Search View -->
<div ui-view="search"></div>
</div>
<!-- Page Content view -->
<div ui-view></div>
The issue is here in the app.js file. When I add the views parameter to the base state, everything stops working(100% blank page). Without that parameter, the page renders correctly, but I have no search view.
app.js:
$urlRouterProvider.otherwise('/');
//
// Now set up the states
$stateProvider
.state('base', {
abstract: true,
templateUrl: 'views/base.html',
views: {
"search": {
templateUrl: "views/search.html"
}
}
})
.state('base.home', {
url: "/",
templateUrl: "views/home.html"
})
.state('base.page2', {
url: "/page2",
templateUrl: "views/page2.html"
});
How do I add views to this parent 'base' state?
UPDATE:
The problem with #actor2019's answer here is that the search view gets reinitialized when the state changes. I'd like the views off the base level to persist through state changes.
The first obvious mistake:
You can't specify controller and template on the state while your using views. They are mutually exclusive...
This is because when there is no "views" but a controller and template on the state, UI-Router automatically creates the "views" property and pulls those properties to an "empty" view...
.state('base', {
abstract: true,
templateUrl: 'views/base.html', //Can't do this
views: { // when this is there.
"search": {
templateUrl: "views/search.html"
}
}
})
Instead do:
.state('base', {
abstract: true,
views: {
"": {
templateUrl: 'views/base.html'
},
"search": {
templateUrl: "views/search.html"
}
}
})
Second problem:
How views targeting works with nested views etc. is not very logical, it may work well if you restrict your self to one view in one view all the way down, but ones you start working with multiple named views it all gets confusing... Add unnamed views on top and many people gets lost...
The way views work in UI-Router is the worst part of UI-Router...
Given you example I am not even entirely sure of the way to target the search view from your abstract parent state... Might be:
.state('base', {
abstract: true,
views: {
"": {
templateUrl: 'views/base.html'
},
"search#base": {
templateUrl: "views/search.html"
}
}
})
If it can even be made to work... Alternatively you can move the search view out of base.html, but I guess you added it in there for a reason.
The whole view concept is the biggest reason why I ended up writing https://github.com/dotJEM/angular-routing instead.
The Child state should be home.search instead of header.search. In your case, you may want to write some abstract state to hold the layout,
base.html
<div class="row-fluid">
<div class="header">
<div class="span3" ui-view="logo"></div>
<div class="span9" ui-view="menu"></div>
</div>
</div>
<div class="row-fluid">
<div class="content">
<div class="span2" ui-view="sidebar"></div>
<div class="span10" ui-view="entry"></div>
</div>
</div>
in app.js
$stateProvider
.state('base',{
abstract:true,
url:'/',
templateUrl: viewBase+'base.html'
})
.state('base.main',{
url:'',
views:{
"logo":{
templateUrl:viewBase+'main/logo.html'
},
"menu":{
templateUrl:viewBase+'main/menu.html'
},
"sidebar":{
templateUrl:viewBase+'main/sidebar.html'
},
"entry":{
templateUrl: viewBase+'main/entry.html'
}
}})
According to the ui-router documentation, when the application is in a particular state—when a state is "active"—all of its ancestor states are implicitly active as well. So, for example, when the "contacts.list" state is active, the "contacts" state is implicitly active as well, because it's the parent state to "contacts.list". Child states will load their templates into their parent's ui-view. I'd reccomend looking over the section of their documentation entitled Nested States & Views to gain a fuller understanding of how to do this.
In the code you have provided us here, the parent state of the search template is home, while
.state('header.search', {
templateUrl: "views/search.html",
controller: "SearchCtrl"
})
implies that the parent state of the search template should be header in order for the view to get loaded correctly. So, I believe the following changes to your app.js will fix your issue.
app.js
$stateProvider
.state('home', {
url: "/",
views: {
'': {
templateUrl: "views/mainContent.html",
controller: "MainCtrl"
},
'header': {
templateUrl: "views/header.html"
},
'footer': {
templateUrl: "views/footer.html"
},
}
})
.state('home.search', {
views: {
'search': {
templateUrl: "views/search.html",
controller: "SearchCtrl"
}
})
.state('anotherPage', {
url: "/anotherPage",
templateUrl: "views/anotherPage.html"
});
This works for me.
$stateProvider
.state('base', {
abstract: true,
url:'/',
templateUrl: 'views/base.html'
})
.state('base.home', {
url: "",
views: {
"search#base": {
templateUrl: "views/searchOfHome.html"
}
//content#base, contentOfHome.html
}
})
.state('base.page2', {
url: "page2",
views: {
"search#base": {
templateUrl: "views/searchOfPage2.html"
}
//content#base, contentOfPage2.html
});
If 'base' is the root state, you don't need the '#base'

I'm trying to build from scratch a very simple angular app using ui-router.
Every page will have the same appearance, and will have the following 4 sections (vertically, from top to bottom):
HEADER (common to all pages)
HORIZONTAL MENU (common to all pages)
CONTENT (this is the only content that will change)
FOOTER (common to all pages)
My index.html has <div ui-view></div> inside the <body> tag.
I also have a simple html file (portal.html) that contains the structure of every page:
<div ui-view="header"></div>
<div ui-view="menu"></div>
<div ui-view="content"></div>
<div ui-view="footer"></div>
I've have created a parent state, where I set the common sections to every page:
$stateProvider
.state('portal', {
url: '/portal',
templateUrl: 'app/main/portal.html',
views: {
header: {
templateUrl: 'app/main/section/header.html'
},
menu: {
templateUrl: 'app/main/section/menu.html'
},
footer: {
templateUrl: 'app/main/section/footer.html'
}
}
});
And some child states (one for each menu option - page), where I set the variable content to every page:
$stateProvider
.state('portal.home', {
url: '/home',
views: {
'content#portal': {
controller: 'HomeCtrl as homeVM',
templateUrl: 'app/portal/home.html'
}
},
resolve: { /* whatever */ }
})
// ... and so on ...
.state('portal.contactUs', {
url: '/contact-us',
views: {
'content#portal': {
controller: 'ContactUsCtrl as contactUsVM',
templateUrl: 'app/portal/contactUs.html'
}
},
resolve: { /* whatever */ }
});
But this won't display anything on screen... Am I missing something here?
I finally found a solution. What actually helped me was this StackOverflow post, that is quite similar to mine, and specially the plunker example shown there.
The mistake was in the state configuration object passed to the $stateProvider.state(). The parent state should be set the following way:
$stateProvider
.state('portal', {
url: '/portal',
views: {
'#': {
templateUrl: 'app/main/portal.html'
},
'header#portal': {
templateUrl: 'app/main/public/header.html'
},
'menu#portal': {
templateUrl: 'app/main/public/menu.html'
},
'footer#portal': {
templateUrl: 'app/main/public/footer.html'
}
}
});
I have this classic ionic view refresh problem:
.state('app', {
url: '/app',
abstract: true,
templateUrl: 'templates/menu.html',
controller: 'AppCtrl'
})
.state('app.menu', {
url: "/menu",
views: {
'menuContent': {
templateUrl: "templates/headmenu.html"
}
}
})
.state('app.menu.media', {
url: "/media/:MediaType",
views: {
'media-tab': {
templateUrl: "templates/tabs/media.html",
controller: "MediaCtrl"
}
}
}).state('app.settings', {
url: "/settings",
views: {
'settingsContent': {
templateUrl: "templates/settings.html",
controller: "SettingsCtrl"
}
}
})
The app start from 'app.menu.media' state, I click on 'settings', the view is loaded, but the problem occurs when I try going back to 'app.menu.media' state, the view is not refreshed (I still have the 'settings' view)
One of the solutions suggested by other devs is using ui-sref-opts="{reload: true, notify: true}" inside a <a ui-sref="app.menu.media" ...> ..</a> tag, but it's not smooth, the users feel like if the app freezes for a short time, and the same goes for the javascript solution: $state.go('app.menu.media', {}, {reload: true});
I know that the controller is not loaded when it is in the same state, but in this example we have different controllers: "MediaCtrl" and "SettingsCtrl", so why we have this problem? Is there any clean solution to fix this problem?
Edit:
This problem occurs even if I'm disabling the cache: $ionicConfigProvider.views.maxCache(0);
After Debuging the app, I found that the problem was not related to cache, but it doesn't mean that enabling the views cache will not affect the app, disabling the cache was important for my case.
So the problem was related to the fact that I was using the same state "app" for both 'media' and 'settings' views, with different view names: "settingsContent" for "app.settings" and "menuContent" for "app.menu". So I had to add these two Ion-nav-views to the template Url linked to the "app" state, which is "menu.html", juste like this:
<ion-nav-view name="menuContent"></ion-nav-view>
<ion-nav-view name="settingsContent"></ion-nav-view>
So when I go back to "app.menu.media" state, the view is indeed loaded, but the "settings" view is still there, and it is hiding my new requested view "media"!
So what I did to fix this issue is to use the same Ion View name:
.state('app.menu', {
url: "/menu",
views: {
'THESAMENAME': {
templateUrl: "templates/headmenu.html"
}
}...
....
.state('app.settings', {
url: "/settings",
views: {
'THESAMENAME': {
templateUrl: "templates/settings.html",
controller: "SettingsCtrl"
}
}
And inside menu.html, I deleted the two previous lines, and replaced theme with:
<ion-nav-view name="THESAMENAME"></ion-nav-view>
I hope this could help someone
I'm working on upgrading a project I found to the latest version of Angular and preparing it for Angular 2 conversion etc. So, I'm using some nested views in Angular using ui-router, and I can only get the nested views to display if they are explicitly included in the index page as ng-template files.
index.jade
script(type="text/ng-template", id="404")
include partials/404
script(type="text/ng-template", id="home")
include partials/home
script(type="text/ng-template", id="private/layout")
include partials/private/layout
script(type="text/ng-template", id="private/home")
include partials/private/home
script(type="text/ng-template", id="private/nested")
include partials/private/nested
script(type="text/ng-template", id="private/nestedAdmin")
include partials/private/nestedAdmin
app.routes.js
(function() {
'use strict';
angular
.module('app.routes', [
'ui.router'
])
.config(function($stateProvider, $urlRouterProvider, $locationProvider) {
var access = routingConfig.accessLevels;
// Public routes
$stateProvider
.state('public', {
abstract: true,
template: "<ui-view/>",
data: {
access: access.public
}
})
.state('public.home', {
url: '/',
templateUrl: 'home'
})
.state('public.404', {
url: '/404',
templateUrl: '404'
});
// Regular user routes
$stateProvider
.state('user', {
abstract: true,
template: "<ui-view/>",
data: {
access: access.user
}
})
.state('user.profile', {
url: '/profile',
templateUrl: 'profile',
controller: 'profileController',
controllerAs: 'vm'
})
.state('user.private', {
abstract: true,
url: '/private',
templateUrl: 'private/layout'
})
.state('user.private.home', {
url: '/',
templateUrl: 'private/home'
})
.state('user.private.nested', {
url: '/nested',
templateUrl: 'private/nested'
})
.state('user.private.admin', {
url: '/admin',
templateUrl: 'private/nestedAdmin',
data: {
access: access.admin
}
});
});
})();
I wanted to remove the whole ng-template part as I felt this would not be efficient when scaling the app up, so I removed the ng-template scripts from the index page. When I do this, the first layer of nested routes work, so routes such as public.home work okay. The problem comes with the second layer of nested views, so now routes such as user.private.home and user.private.nested do not work and aren't displayed.
Here is the generated HTML with and without the ng-templates scripts:
WITH ng-templates scripts
<div data-ui-view="" class="col-md-6 col-md-pull-4 ng-scope">
<p class="ng-scope">Only visible to users</p>
</div>
WITHOUT ng-templates
<div data-ui-view="data-ui-view" class="col-md-6 col-md-pull-4 ng-scope"></div>
Any ideas?
Found my own answer here: https://github.com/angular-ui/ui-router/issues/247
Turns out it's an issue with Jade/ui-router, I'm not sure which. The solution is to either include ui-view using pure HTML <div ui-view></div> or by placing doctype html at the top of your partial file.
It was a confusing issue because the nested templates worked fine when injected into $templateCache using ng-template as shown in my post.
I am creating a web app to help students in science, history and math. When you first land on the site I have a home/landing page. When you click get started I route to /exam/instructions. Each of my steps instructions, math and science our templates that I load into the ui-view="exam-detail". Currently the whole ui-view loads when I navigate to and from instructions through sciences. Ideally I simply want an area for pagination and an area for the subject matter and only want the ui-view="exam-detail" to update with the correct template.
I have not used UI-Router at all and any assistance would be greatly appreciated.

There is a working plunker
There is a similar Q & A in fact, with working plunker:
Angular UI Router - Nested States with multiple layouts
Solution here, is to move the static view from child to parent. It won't be reloaded for each child (view is reloaded only if parent state is changed). We will use absolute naming (see included links for more details)
So this is the code adjustment
.state('exam', {
url: '/exam/:step',
abstract: true,
// the root view and the static pagination view
// will be defined here, so we need views : {}
views: {
'':{
templateUrl: 'app/state-exam/exam.html',
controller: 'ExamController',
controllerAs: 'examController',
},
// absolute naming targets the view defined above
'exam-pagination#exam':{
templateUrl: 'app/state-exam/exam-pagination.html'
},
}
})
.state('exam.instructions', {
url: '/instructions',
views: {
// 'exam-pagination':{}, // defined in parent
'exam-detail' : {
templateUrl: 'app/state-exam/exam-instructions.html'
}
}
})
.state('exam.math', {
url: '/math',
views: {
// 'exam-pagination':{}, // defined in parent
'exam-detail' : {
templateUrl: 'app/state-exam/exam-math.html'
}
}
});

Angular UI router nested views
Angular-UI Router: Nested Views Not Working
The working example is here
I have a fairly simple todo app using angular.js for which I am using the ui-router library. I looked through the ui-router example on github (https://github.com/angular-ui/ui-router/tree/master/sample) but was unable to figure out what I am doing wrong. In my app I have a sidebar navigation view (with the list of things todo) and a content view (which displays the todo item's details when clicked). The problem I have is that when I navigate to /todo/exampleItem the content view updates and the navigation panel is reloaded as well. This doesn't effect the functionality of the app but I would like to avoid the navigation panel flickering each time you click on an item.
Here is my code to handle the state changes:
app.config(function ($stateProvider) {
$stateProvider
.state('todo', {
url: "/todo",
views: {
"navPanel": {
templateUrl: "./navPanel.html",
controller: 'PanelController'
}
}
})
.state('todo/:item', {
url: "/todo/:item",
views: {
"PanelView": {
templateUrl: "./navPanel.html",
controller: 'PanelController'
},
"ContentView": {
templateUrl: "./content.html",
controller: 'ContentController'
}
}
})
});
In my index.html my views are set up as follows:
<div class="column" data-ui-view="PanelView"></div>
<div class="column" data-ui-view="ContentView"></div>
Is there some way I can stop the navPanel view from being reloaded each time a new item is clicked?
