Angular ui-router variable in nested view - javascript

I'm currently working on an app where I have multiple nested views, they sort of look like this:
- ui-view
- ui-view="header"
- ui-view="nav"
- ui-view="body"
My states are defined as follows:
.state('index', {
url: '', // default route
templateUrl: 'welcome.html'
})
.state('app', {
abstract: true,
templateUrl: 'app.template.html' // This template contains the 3 different ui-views
})
// I'm using a different state here so I can set the navigation and header by default
.state('in-app', {
parent: 'app',
abstract: true,
views: {
'nav#app': { '...' },
'header#app': { '...' }
}
})
// In-app routes
.state('dashboard', {
parent: 'in-app',
url: '/app/dashboard'
views: {
'body#app': { '...' }
}
})
.state('users', {
parent: 'in-app',
url: '/app/users'
views: {
'body#app': { '...' }
}
})
.state('settings', {
parent: 'in-app',
url: '/app/settings'
views: {
'body#app': { '...' }
}
})
At the moment this works great, but for the in-app routes I would like to define a title that is displayed in the header#app view.
What would be the best way to do this? At the moment I can only think of either setting a variable on the $rootScope, or sending out an event. But for both of those I would need a controller.
Is there a way I could do this directly from my routes config?

The sample applicaiton of the UI-Router, uses this code:
ui-router / sample / app / app.js
.run(
[ '$rootScope', '$state', '$stateParams',
function ($rootScope, $state, $stateParams) {
// It's very handy to add references to $state and $stateParams to the $rootScope
// so that you can access them from any scope within your applications.For example,
// <li ng-class="{ active: $state.includes('contacts.list') }"> will set the <li>
// to active whenever 'contacts.list' or one of its decendents is active.
$rootScope.$state = $state;
$rootScope.$stateParams = $stateParams;
}])
And that means, that with data : {} feature:
Attach Custom Data to State Objects
You can attach custom data to the state object (we recommend using a data property to avoid conflicts).
// Example shows an object-based state and a string-based state
var contacts = {
name: 'contacts',
templateUrl: 'contacts.html',
data: {
customData1: 5,
customData2: "blue"
}
}
we can do this:
.state('in-app', {
parent: 'app',
abstract: true,
views: {
'nav#app': { '...' },
'header#app': { '...' }
}
data: { title : "my title" },
})
And use it in some template like:
<div>{{$state.current.data.title}}</div>
Some summary.
We can place state and params into $rootScope, so we can access it without any controller anyhwere.
We can declare some more custom stuff via data and use it as a title ... anyhwere

ui router nested views condtions

is it possible to create a nested views in ui router with conditions?
The conditions is assigned to the user roles.
For example I have two types of users: admin and user.
If user is opening the setting page then ui router is adding only this view which is assign to his role.
Here is example of my config code
var app = angular.module('myApp', ['ui.router']);
app.config(function ($stateProvider, $urlRouterProvider){
$stateProvider
.state('home', {
url: '/home',
templateUrl: '/home.html',
controller: 'homeController'
})
.state('settings', {
url: '/settings',
data: {
roles: ['admin', 'moderator', 'user']
},
views:{
'':{
templateUrl:'/settings.html',
},
'piView#settings':{
data: {
roles: ['user']
},
templateUrl:'/personalInformation.html'
},
'permissionsView#settings':{//load this view if user is administrator
//I need some condition for this
data: {
roles: ['admin']
},
templateUrl: '/permissionsView.html'
}
},
controller: 'settingsController'
});
$urlRouterProvider.otherwise( function($injector) {
var $state = $injector.get("$state");
$state.go('/home');
});
});
The view will be injected for each user (admin or anonymous). But we can manage which view. The best vay would be to use templateProvider.
Based on this Q & A:
Confusing $locationChangeSuccess and $stateChangeStart
I used the plunker from above source and adjusted it a bit
So, let's have these two targets (inside of index.html)
<div ui-view="onlyForAdmin"></div>
<div ui-view=""></div>
And a state public, which for Admin will reveal even content of the onlyForAdmin, with settings like this:
.state('public', {
url: "/public",
data: { isPublic: true },
views: {
'#' : {
templateUrl: 'tpl.html',
data: { isPublic: true },
},
'onlyForAdmin#' : {
templateProvider: ['$templateRequest','userService',
function($templateRequest,userService)
{
if(userService.isAdmin())
{
return $templateRequest("justForAdmin.html");
}
return ""; // other than admin will see nothing
}
]
}
}
})
the content of the justForAdmin.html (e.g. <h2>just for admin</h2>) will be injected only of some authorization service will find user as admin...

Accessing child state parameters in parent in Angular UI-Router

I have the following state configuration. How can I get id parameters in index state # view so that it could be accessible by both, left and detail views controllers? Now if I try to access it via $state.params.id it is undefined, but if I console.log($state) I can see the parameter in my console. I only need the parameter if available on first load of left view.
$stateProvider
.state('index', {
url: '/',
views: {
'#' : {
template: '/**/'
resolve: {
params: function ($state) {
return $state.params.id;
}
}
},
'left#index' : {
template: '/**/',
controller: 'AppController',
controllerAs: 'app'
},
'main#index' : {
template: '/**/'
}
})
.state('index.detail', {
url: '/:id',
views: {
'detail#index' : {
template: '/**/',
controller: 'DetailController',
controllerAs: 'detail',
}
}
});

Sub-views in Angular UI router and Controller inheritance?

I have a view state like this, with 3 views:
(function() {
'use strict';
angular.module('pb.tracker').config(function($stateProvider) {
$stateProvider.state('tracker', {
url: '/tracker',
controller: 'TrackerController as tracker',
data: {
pageTitle: 'Parcel Tracker',
access: 'public',
bodyClass: 'tracker'
},
resolve: {
HistoryResolve: function($log, MockDataFactory) {
return MockDataFactory.query({
filename: 'trackingdata'
});
}
},
views: {
'': {
templateUrl: 'modules/tracker/templates/tracker.html'
},
'controls#tracker': {
templateUrl: 'modules/tracker/templates/tracker-controls.html'
},
'content#tracker': {
templateUrl: 'modules/tracker/templates/tracker-details.html'
}
}
});
});
})();
I want to use the controller TrackerController for all the views in the state. I thought they would simple inherit the parent one.
But so far, even a simple log does not show in the console. The controller is
(function() {
'use strict';
angular.module('pb.tracker').controller('TrackerController', function($log, HistoryResolve) {
var _this = this;
// _this.packageHistory = HistoryResolve;
$log.debug('foo');
});
})();
So, my console should read "foo" regardless, yes? Nothing in the console. No errors. The works fine, the views load the templates. I am only stuck on the controller. I've never run into this.
UPDATE
OK, I am trying to define a parent state, and assign the controller to that. However, what I have below is no yielding nothing at all in the browser...
(function() {
'use strict';
angular.module('pb.tracker').config(function($stateProvider) {
$stateProvider.state('tracker', {
url: '/tracker',
abstract: true,
controller: 'TrackerController as tracker',
data: {
pageTitle: 'Parcel Tracker',
access: 'public',
bodyClass: 'tracker'
},
resolve: {
HistoryResolve: function($log, MockDataFactory) {
return MockDataFactory.query({
filename: 'trackingdata'
});
}
}
})
.state('tracker.details', {
url: '/tracker/details',
views: {
'': {
templateUrl: 'modules/tracker/templates/tracker.html'
},
'controls#tracker': {
templateUrl: 'modules/tracker/templates/tracker-controls.html'
},
'content#tracker': {
templateUrl: 'modules/tracker/templates/tracker-details.html'
}
}
});
});
})();
When you define named views (using the views property, aka "named views"), the template properties of the state are overriden by each named view. From the documentation:
If you define a views object, your state's templateUrl, template and templateProvider will be ignored. So in the case that you need a parent layout of these views, you can define an abstract state that contains a template, and a child state under the layout state that contains the 'views' object.
Note that a template is always paired with a controller. So since it doesn't use the template properties, there's no need for it to instantiate the controller. You have two choices:
Use specify the controller for each view. This will instantiate a controller for each named view, probably not what you want.
Create a parent state to this state, which is abstract and uses the controller. Note that your state above doesn't have a child/parent relationship, it's just one state w/some named views.

AngularJS UI Router data persists when navigating from grand-child to parent

I am having weird issue probably caching issue while navigating from grand-child(/dashboard/1/production) to parent(/dashboard).
Following are few screenshots:
The selections i.e Delphi-UI and production shouldn't persists.
Following is my snippet of application config:
$stateProvider
.state('root', {
url: '/',
views: {
'header': {
templateUrl: 'ngapp/templates/header.html'
}
}
})
// dashboard routes
.state('root.dashboard', {
url: 'dashboard',
views: {
'content#' : {
templateUrl: 'ngapp/home/templates/dashboard.html',
controller: 'DashboardCtrl',
controllerAs: 'vm'
}
}
})
.state('root.dashboard.app', {
url: '/{id:int}',
views: {
'body#root.dashboard' : {
templateUrl: 'ngapp/home/templates/dashboard-body.html',
controller: 'DashboardBodyCtrl'
}
}
})
.state('root.dashboard.app.env', {
url: '/:name',
views: {
'body#root.dashboard' : {
templateUrl: 'ngapp/home/templates/env-content.html',
controller: 'EnvContentCtrl'
}
}
});
And DashboardCtrl is:
controllers.controller('DashboardCtrl', ['$scope', '$http', '$state', '$timeout', 'appsFactory', function($scope, $http, $state, $timeout, appsFactory) {
$scope.envs = [];
$scope.deps = [];
$scope.envBtnText = $scope.appBtnText = "Choose here";
$scope.headerTitle = "Environment Configuration And Management";
$scope.appStatus = {
isopen: false
};
$scope.envStatus = {
isopen: false
};
appsFactory.list(function(data) {
$scope.apps = data;
});
}]);
Full controller code : http://goo.gl/BWtiU5
Project hosted here : https://github.com/budhrg/atlantis-dashboard
Also, navigating back to Atlantis UI(dashboard) doesn't reset data like
$scope.envs, $scope.deps, $scope.envBtnText and $scope.appBtnText.
What might be issue here? Am I missing anything?
Nested States & Views
When the application is in a particular state—when a state is "active"—all of its ancestor states are implicitly active as well. Below, when the "contacts.list" state is active, the "contacts" state is implicitly active as well, because it's the parent state to "contacts.list".
Your controller isn't getting re-instantiated (expected). There are a couple ways to handle this.

Angular UI-Router passing data between states with go function does not work

I just started learning angularjs and I am using angular-ui-router. I am trying to send data from one state to another using $state.go but I have no success. Here is what I have so far:
I have not included the html intentionally because I assumed it was not needed if it is needed please tell me and I will add it.
I have configured my states as below:
$stateProvider
.state('public', {
abstract: true,
templateUrl: 'App/scripts/main/views/PublicContentParent.html'
})
.state('public.login', {
url: '/login',
templateUrl: 'App/scripts/login/views/login.html',
controller: 'loginCtrl'
})
$stateProvider
.state('private', {
abstract: true,
templateUrl: 'App/scripts/main/views/PrivateContentParent.html'
})
.state('private.visits', {
url: '/visits',
views: {
'main': {
controller: 'visitsListCtrl',
templateUrl: 'App/scripts/visits/views/VisitsList.html'
}
}
});
When my LoginController is invoked it will execute the below code:
loginModule.controller('loginCtrl', ['$state', function ($scope, $state) {
$state.go('private.visits', { name : "Object"});
}]);
When the private.visits page is active, I am trying to print the $stateParams:
visitsModule.controller('visitsListCtrl', ['$stateParams',
function ($stateParams) {
console.log($stateParams);
}]);
As things state $stateParams is an empty object. I expected it to to contain the object I passed in loginCtrl.
EDIT
It seems that if private.visits url has this url format '/visits/:name' and I also add the property params: ["name"] I get access to the object I send from the public.login state.
The side effect is that the parameters are added to the url which is logical.
I tried doing the same thing with a child state with no url, and in this case it seems that I do not have access to the params I passed from public.login.
How do I send data in child states?
What you have to do is to define the name param in the private.visits state like:
$stateProvider
.state('public', {
abstract: true,
templateUrl: 'App/scripts/main/views/PublicContentParent.html'
})
.state('public.login', {
url: '/login',
templateUrl: 'App/scripts/login/views/login.html',
controller: 'loginCtrl'
})
$stateProvider
.state('private', {
abstract: true,
templateUrl: 'App/scripts/main/views/PrivateContentParent.html'
})
.state('private.visits', {
// NOTE!
// Previously, we were only passing params as an array
// now we are sending it as an object. If you
// send this as an array it will throw an error
// stating id.match is not a function, so we updated
// this code. For further explanation please visit this
// url http://stackoverflow.com/a/26204095/1132354
params: {'name': null},
url: '/visits',
views: {
'main': {
controller: 'visitsListCtrl',
templateUrl: 'App/scripts/visits/views/VisitsList.html',
resolve: {
name: ['$stateParams', function($stateParams) {
return $stateParams.name;
}]
}
}
}
});
And then in the controller access to the name:
visitsModule.controller('visitsListCtrl', ['name',
function (name) {
console.log(name);
}]);
Hope it help you!
When you say:
$state.go('private.visits', { name : "Object"});
You're not passing data to the private.visits state, but rather you're setting a parameter to the private.visits state, which doesn't even support parameters as you have not defined parameters for it in the state config. If you want to share data between states use a service, or if your states have a parent-child relationship then the child state will have access to the parent states data. Seeing as how you don't want the data to sow up in your URLs, I would use a service (getters/setters) to achieve this.
