Update $state variable in 1 module from another

https://plnkr.co/edit/PWuKuVw9Dn9UJy6l8hZv?p=preview
I have 3 modules, routerApp, tickers and tags. Basically trying to rebuild my app out of smaller mini-apps.
The routerApp template contains the 2 directives for the other modules.
Expected
When you login, then click on the Count button in the tickers.component, I want to send the counter var into the tags.component $scope via $state.go.
Result
Nothing happens. No $state/variable update in the tags.component
Plnkr app.js code:
// TICKERS app module
var tickers = angular.module('tickers', ['ui.router'])
tickers.config(function($stateProvider) {
const tickers = {
name: 'tickers',
url: '/tickers',
parent: 'dashboard',
templateUrl: 'tickers-list.html',
bindToController: true,
controllerAs: 'tik',
controller: function() {
}
}
$stateProvider
.state(tickers);
})
tickers.component('tickersModule', {
templateUrl: 'tickers-list.html',
controller: function($scope, $state) {
console.log('Tickers init')
$scope.counter = 0;
$scope.increase = function() {
$scope.counter++;
console.log('increase', $scope.counter)
$state.go('dashboard.tags', { counter: $scope.counter });
}
}
})
// TAGS app module
var tags = angular.module('tags', ['ui.router'])
tags.config(function($stateProvider) {
const tags = {
name: 'tags',
url: '/tags?counter',
parent: 'dashboard',
params: {
counter: 0
},
templateUrl: 'tags-list.html',
bindToController: true,
controllerAs: 'tags',
controller: function($state) {
}
}
$stateProvider
.state(tags);
})
tags.component('tagsModule', {
templateUrl: 'tags-list.html',
controller: function($scope, $state) {
// Expecting this to update:
console.log('Tags init', $state)
$scope.counter = $state.params.counter;
}
})
// MAIN ROUTERAPP module
var routerApp = angular.module('routerApp', ['ui.router', 'tickers', 'tags']);
routerApp.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/login');
const login = {
name: 'login',
url: '/login',
templateUrl: 'login.html',
bindToController: true,
controllerAs: 'l',
controller: function($state) {
this.login = function() {
$state.go('dashboard', {})
}
}
}
const dashboard = {
name: 'dashboard',
url: '/dashboard',
templateUrl: 'dashboard.html',
controller: function() {
}
}
$stateProvider
.state(login)
.state(dashboard);
})
dashboard.html
<div class="jumbotron text-center">
<h1>The Dashboard</h1>
</div>
<div class="row">
<tickers-module></tickers-module>
<tags-module></tags-module>
</div>
The function in the tickers component that is trying to update the $state of the tags component:
$scope.increase = function() {
$scope.counter++;
console.log('increase', $scope.counter)
$state.go('dashboard.tags', { counter: $scope.counter });
}
Also tried: $state.go('tags', { counter: $scope.counter });
Finally the tags.component.
Note that here I'm not seeing the $scope.counter update nor the controller for the component getting refreshed due to a state change.
tags.component('tagsModule', {
templateUrl: 'tags-list.html',
controller: function($scope, $state) {
console.log('Tags init', $state)
$scope.counter = $state.params.counter;
}
})
Is the way I am architecting this going to work? What am I missing?
Update: Added some $rootScope events to watch for $state changes, hope this helps:
This is after clicking the login button and going from the login state to the dashboard state, but still nothing for clicking on the Count button.

So, it looks like you're properly passing the parameters in your $state.go call.
I think the issue here is that you're not properly handling the state parameters you're passing from the tickers component to the tags component.
Try injecting $stateParams into your tags component and pull the parameters off that object, for example (in your tags controller):
$scope.counter = $stateParams.counter;

Figured it out!
https://plnkr.co/edit/CvJLXKYh8Yf5npNa2mUh?p=preview
My problem was that in the $state object tags, I was using the same template as the tags.component.
Instead I needed to change it to something like <p>{{ counter }}</p>
var tags = angular.module('tags', ['ui.router'])
tags.config(function($stateProvider) {
const tags = {
name: 'tags',
url: '/tags',
parent: 'dashboard',
params: {
counter: 0
},
template: '<p>{{ counter }}</p>',
bindToController: true,
controller: function($scope, $state) {
console.log('tags state object', $state)
$scope.counter = $state.params.counter;
}
}
$stateProvider
.state(tags);
})
tags.component('tagsModule', {
templateUrl: 'tags-module-template.html',
controller: function($scope, $state) {
}
})
Then in my tags-module.template.html I needed to add a <div ui-view></div>
<div class="jumbotron text-center">
<h2>Tags list</h2>
<div ui-view></div> // <- here and this is where the $state object updates
{{ counter }}
</div>

Implementing a navbar nested view in angular ui router

Am new to the angular js.
Am implementing a nested ui view but the problem is when checking the current state of a page it returns many objects such that i cant use $state.current to set the ng-show
I would like the navbar shown and hidden in some states.
I have tried
The main index.html page
<html>......
<body ng-app="myapp">
<nav ng-controller="headerCtrl" ng-show="shownav()" >
//here is the navbar code..The shownav is defined on the headerCtrl
</nav>
<div ui-view> </div>
//Angular js, controllers and services links
</body>
</html>
The app.js code
var app = angular.module('myApp', ['ui.router']);
app.controller('headerCtrl',function($scope, $state) {
$scope.shownavbar = function(){
var state = $state.current;
if(state ==='login' ){
return false;
}else{
return true;
}
}
app.config(function($stateProvider, $urlRouterProvider, $httpProvider){
$stateProvider
.state('login', {
url:'/login',
templateUrl: 'templates/index/login/login.html',
controller: 'loginCtrl'
})
.state('dash', {
url: '/dash',
templateUrl:'templates/layout/dashboard.html',
abstract:true
})
.state('dash.call',{
url: '/call',
templateUrl: 'templates/index/calls/calls.html',
controller: 'callCtrl'
})
.state('dash.profile', {
url: '/profile',
templateUrl: 'templates/index/account/profile/profile.html',
controller: 'profileCtrl'
})
});
I would like the navbar hidden for some states like when a user is on the login state
At the headerctrl i have also tried
$scope.shownavbar = function(){
var state = $state.current;
$log.info(state);
}
This returns in the console:
angular.js:13708 Object {name: "", url: "^", views: null, abstract: true}
angular.js:13708 Object {name: "", url: "^", views: null, abstract: true}
angular.js:13708 Object {url: "/login", templateUrl: "templates/index/login/login.html", controller: "loginCtrl", name: "login"}
angular.js:13708 Object {url: "/login", templateUrl: "templates/index/login/login.html", controller: "loginCtrl", name: "login"}
angular.js:13708 Object {url: "/login", templateUrl: "templates/index/login/login.html", controller: "loginCtrl", name: "login"}
WHAT COULD BE THE PROBLEM

I can think in two ways to solve this.
First solution
EDITED
inside your run() put a function to see when the state is changing and hide or show the navbar.
myApp.run(function ($rootScope, $state) {
$rootScope.navbar = false;
$rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {
if (toState.name === 'login') {//toState variable see the state you're going
$rootScope.navbar = false;
} else {
$rootScope.navbar = true;
}
});
});
and change in your ng-show="navbar"
Second solution
the second solution i can think is you use multiple views.
$stateProvider
.state('login', {
url: '/',
views: {
'navbar': {
templateUrl: null,
controller: null
},
'body': {
templateUrl: "views/login.html",
controller: 'LoginController'
}
}
})
.state('home', {
url: '/home',
views: {
'navbar': {
templateUrl: "views/navbar.html",
controller: null
},
'body': {
templateUrl: "views/inicio.html",
controller: null
}
}
});
and in your html views put something similar to this:
<div ui-view="navbar"></div>
<div ui-view="body"></div>

How to load login page as first page

I am using ionic framework. I am trying to load login page as first page but cant see its just getting an empty page.
My code looks like
app.js:
app.config(function ($stateProvider, $urlRouterProvider) {
$stateProvider
.state('app', {
url: "/app",
abstract: true,
templateUrl: "templates/menu.html",
controller: 'AppCtrl'
})
and controller:
.controller('AppCtrl', function ($scope, $state, $ionicModal) {
$ionicModal.fromTemplateUrl('templates/login.html', function(modal) {
$scope.loginModal = modal;
},
{
scope: $scope,
animation: 'slide-in-up',
focusFirstInput: true
}
);
//Be sure to cleanup the modal by removing it from the DOM
$scope.$on('$destroy', function() {
$scope.loginModal.remove();
});
.controller('LoginCtrl', function ($scope, $state, AuthenticationService) {
$scope.message = "";
$scope.user = {
username: null,
password: null
};
$scope.login = function () {
AuthenticationService.login($scope.user);
};
$scope.$on('event:auth-loginRequired', function (e, rejection) {
console.log('handling login required');
$scope.loginModal.show();
});
$scope.$on('event:auth-loginConfirmed', function () {
$scope.username = null;
$scope.password = null;
$scope.loginModal.hide();
});
But still cant see it.
my app looks like
https://github.com/keithdmoore/ionic-http-auth but without the home page.
Thnx!

try to change your app.config section.
app.config(function ($stateProvider) {
$stateProvider.otherwise({ redirectTo: '/login' });
$stateProvider
.state('app', {
url: "/app",
abstract: true,
templateUrl: "templates/menu.html",
controller: 'AppCtrl'
}).state('login', {
url: "/login",
templateUrl: "login.html page url",
controller: 'login controller'
}));
don't need to write any code appcontroller'. Whenever you run the application the url path is should be empty. So this line $stateProvider.otherwise({ redirectTo: '/login' }); helps to open the login screen.

Trying to use nested views in angularjs with ui-router get a blank page

My setup
app/learning/learning.js
angular.module('meanApp')
.config(function($stateProvider) {
$stateProvider
.state('learning',{
templateUrl: 'app/learning/learning.html',
url: '/learning',
controller: 'LearnCtrl',
views: {
'list': {
templateUrl: 'app/learning/learning.list.html',
controller: function($scope){ }
},
'magic': {
templateUrl: 'app/learning/learning.magic.html',
controller: function($scope){ }
}
}
});
});
app/learning/learning.html
<h1>Learning</h1>
<div ui-view="list"></div>
<div ui-view="magic"></div>
app/learning/learning.list.html
<p>A list</p>
app/learning/learning.magic.html
<h2>Magic</h2>
when I navigate to /learning I get a blank page, I'm not sure what I'm doing wrong so any help would be greatly appreciated.

You shouldn't load the base template inside state when there are nested ui-view,
Define the base template inside views.
Route Code
angular.module('meanApp')
.config(function($stateProvider) {
$stateProvider
.state('learning',{
url: '/learning',
views: {
'': {
templateUrl: 'app/learning/learning.html',
controller: 'LearnCtrl'
},
'list#learning': { //you missed state name here
templateUrl: 'app/learning/learning.list.html',
controller: function($scope){ }
},
'magic#learning': { //you missed state name here
templateUrl: 'app/learning/learning.magic.html',
controller: function($scope){ }
}
}
});
});
This could Help you, Thanks.

The problem was that I was trying to load the base template inside state and I missed out the state name as Pankaj said, so the solution is...
angular.module('meanApp')
.config(function($stateProvider) {
$stateProvider
.state('learning',{
url: '/learning',
views: {
'': {
templateUrl: 'app/learning/learning.html',
controller: 'LearnCtrl'
},
'list#learning': { //you missed state name here
templateUrl: 'app/learning/learning.list.html',
controller: function($scope){ }
},
'magic#learning': { //you missed state name here
templateUrl: 'app/learning/learning.magic.html',
controller: function($scope){ }
}
}
});
});

AngularJS : angular-ui-router always redirects to $urlRouterProvider.otherwise location

I'm trying to create an SPA where you have to be logged in to access almost everything. So naturally, the default screen you see is the login screen. However, after a user has logged in, no matter what the ui-sref is, ui-router redirects to the login page (even when the user is authenticated). Here is my ui-router code:
(function () {
'use strict';
angular
.module('app', ['ui.router', 'satellizer'])
.config(function ($stateProvider, $urlRouterProvider, $authProvider, $httpProvider, $provide) {
$httpProvider.interceptors.push(['$q', '$injector', function($q, $injector){
return {
responseError: function (rejection) {
var $state = $injector.get('$state');
var rejectionReasons = ['token_not_provided', 'token_expired', 'token_absent', 'token_invalid'];
angular.forEach(rejectionReasons, function (value, key) {
if (rejection.data.error === value) {
localStorage.removeItem('user');
$state.go('auth');
}
});
return $q.reject(rejection);
},
response: function(response) {
var authorization = response.headers('authorization');
if(authorization !== null) {
authorization = authorization.substr(7).trim();
//console.log(authorization);
var $auth = $injector.get('$auth');
$auth.setToken(authorization);
}
return response;
}
}
}]);
$authProvider.loginUrl = 'mingdaograder/api/authenticate';
$stateProvider
.state('users', {
url: '/users',
templateUrl: 'views/userView.html',
controller: 'UserController as user'
})
.state('subjects', {
url: '/users/:user_id/subjects',
templateUrl: 'views/subjectsView.html',
controller: 'SubjectsCtrl as subjectsCtrl'
})
.state('subject', {
url: '/users/:user_id/subjects/:subject_id',
templateUrl: 'views/subjectView.html',
controller: 'SubjectCtrl as subjectCtrl'
})
.state('auth', {
url: '/auth',
templateUrl: 'views/authView.html',
controller: 'AuthController as auth'
});
//.state('otherwise', {
// url: '*path',
// templateUrl: 'views/authView.html',
// controller: 'AuthController as auth'
//});
//$urlRouterProvider.otherwise('/auth');
$urlRouterProvider.otherwise(function($injector, $location) {
console.log("Could not find " + $location);
$location.path('/auth');
});
})
.run(function ($rootScope, $state, $log) {
$rootScope.$on('$stateChangeStart', function (event, toState) {
console.log(toState.name);
var user = JSON.parse(localStorage.getItem('user'));
if (user) {
$rootScope.authenticated = true;
$rootScope.currentUser = user;
}
}
);
}
);
})();
Anytime I try to use $state.go(any state name here) or even type the address into the address bar, I am always redirected to the auth state. On the console the message is "Could not find http://localhost/#/" for every single route. I can type in http://localhost/#/users/5/subjects and I get the same message.
Here is one of my controllers doing a redirect:
(function () {
'use strict';
angular
.module('app')
.controller('AuthController', AuthController);
function AuthController($auth, $state, $http, $rootScope, $log) {
var vm = this;
vm.loginError = false;
vm.loginErrorText;
vm.login = function () {
var credentials = {
username: vm.username,
password: vm.password
};
$auth.login(credentials).then(function () {
return $http.get('api/authenticate/user');
}, function (error) {
vm.loginError = true;
vm.loginErrorText = error.data.error;
}).then(function (response) {
var user = JSON.stringify(response.data.user);
localStorage.setItem('user', user);
$rootScope.authenticated = true;
$rootScope.currentUser = response.data.user;
//$log.info('From AuthCtrl: ' + $rootScope.currentUser.id);
$state.go('subjects', {user_id:$rootScope.currentUser.id});
});
}
}
})();
Any ideas what I'm doing wrong? Thanks a lot for your time.
Update: Ok, I haven't found a way to fix it but I think I may have found a possible cause. It seems to only happen for the routes with parameters. For example, if I go to the users state, whose path is /users, there is no redirect. However, if I go to the subjects state, whose path is /users/:user_id/subjects, it does redirect. It's like the Url matching service can't recognize that /users/5/subjects matches /users/:user_id/subjects, so redirects. Any ideas how to work around this?

I found I didn't have a '/' at the beginning of my initial state url. Every time I navigated to the state, the missing '/' seemed to push it into the stateProvider.otherwise.
state1: 'opportunity'
state1Url : '/opportunity/' <== added initial forward slash to make it work.
state2: 'opportunity.create'
state2Url : 'create/'

The first path to be recognised will be the selected as the current location. This means that the order of your route definitions is crucially important. In your case you only have a single catch-all otherwise route definition and since all routes match this then all routes are directed to your login page ignoring any other route definitions you may have, including all your stateProvider state definitions.
One way to fix this is to remove the urlRouterProvider route definition altogether and instead use the *path syntax provided by ui-router to create an alternative otherwise state (which must be defined last for the same reasons given above).
Therefore your code might look something like this:
$stateProvider
.state('auth', {
url: '/auth',
templateUrl: 'views/authView.html',
controller: 'AuthController as auth'
})
.state('users', {
url: '/users',
templateUrl: 'views/userView.html',
controller: 'UserController as user'
})
.state('subjects', {
url: '/users/:user_id/subjects',
templateUrl: 'views/subjectsView.html',
controller: 'SubjectsCtrl as subjectsCtrl'
})
.state('subject', {
url: '/users/:user_id/subjects/:subject_id',
templateUrl: 'views/subjectView.html',
controller: 'SubjectCtrl as subjectCtrl'
})
.state("otherwise", {
url: "*path",
templateUrl: 'views/authView.html',
controller: 'AuthController as auth'
});

From experience, this is either due to the / missing at either the beginning or the end of the url route property definition.
Make sure for parent routes to add the initial forward slash to your routes.
.state('checkers', {
url: '/checkers/',
templateUrl: 'checkers.html',
controller: 'CheckersController',
title: 'Checker',
})
