I have an <ng-view></ng-view> that is filled with a partial html file when a button is clicked i.e Sign In
myApp.js
var myApp = angular.module("myApp", ['ngRoute']);
//Define Routing for app
myApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/signin', {
templateUrl: 'signin.ejs'
}).
when('/signup', {
templateUrl: 'signup.ejs'
}).
when('/myAccount', {
templateUrl: 'myAccount.ejs'
}).
otherwise({
//home page
});
}]);
What I want to know is, how can fill this ng-view based on data that is sent by the server. For example, if the server renders the index.html with data {page: '/signin'} how can I let Angular know that I want to to populate the ng-view with 'signin.ejs'??
Any help is appreciated. Thank you!!
EDIT:
I have someone logged in to the site and on a page I provide a "switch account" button. So what I want to do is, when that is clicked, post to the server /logout route so the session can be cleared, and then change the page to the signin page (partial html file) and populate the username field with the account that they are switching to
Your ejs needs to be rendered by nodejs so you need to apply your the routing there.
You need to come up with a way to identify the route path like '/partials/:filename'
app.route('/partials/:filename').get(funcs.partials);
Then you handle the request and render your ejs or plain you just send(html) and you use the path module to locate and manipulate the url string.
exports.partials = function(req, res, next, filename) {
res.render(filename, vars);
};
Then your angular is like, though signin is probably not the best example.
$routeProvider.
when('/signin', {
templateUrl: '/partials/signin'
})

I need some help.I am facing some issues. I could not get the pages after refreshing again using Angular.js. I am explaining my code below.
route.js:
var app=angular.module('demo',['ui.router']);
app.run(function($rootScope, $state) {
$rootScope.$state = $state;
});
compliance.config(function($stateProvider, $urlRouterProvider,$locationProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider
.state('/', {
url: '/',
templateUrl: 'View/demo1.html',
controller: 'demoController'
})
.state('demo2', {
url: '/demo2',
templateUrl: 'View/demo2.html',
controller: 'demo2Controller'
})
$locationProvider.html5Mode({
enabled: true,
requireBase: true
});
});
index.html:
<div ui-view></div>
demo1.html:
demoController.js:
$scope.goToAuditDetailPage=function(){
$state.go('demo2',{}, { reload: true });
}
Here when user will open the link http://localhost/NABH/ the demo1.html page will come and inside that page there is one click event, when user will click on that link the demo2.html page is coming and the URL is http://localhost/NABH/demo2. But In this case when user will refreshing that link http://localhost/NABH/demo2 again this The requested URL /NABH/demo2 was not found on this server. error is coming. Here I need after refreshing also that page should work as per expected.Please help.
You are using html5mode with your routes, therefore the browser changes the routes of your app as they are come from the server, when ever the user press on the refresh button, the browser sends a request with your client route, and your server doesn't aware of it.
One of the simplest solution is to make the server "answer" to all the routes with your client app, in that way, the request with your client rout with be answered with index.html shell (as it answered when you navigate to /), and the client app will check the current route and render the proper page (it's done automatically).
I have the following routing config
myApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'partials/list.html',
controller: 'contactListCtrl'
}).
when('/new', {
templateUrl: 'app/partials/form.html',
controller: 'contactAddCtrl'
}).
otherwise({
redirectTo: '/'
});
}]);
my home page('/') simply loads a number of contacts and its contactListCtrl is like
myApp.controller('contactListCtrl', function($scope, $http) {
$http.get("list")
.then(function(response) {
$scope.contact_list = response.data;
});
});
So when I load the home page on browser, it loads the template and then send another request ('/list') to server to get the contacts (json). so the browser sends 2 requests to the server.
Is this normal in AngularJS development to send 2 requests simultaneously to get template along with data? Is there any work around to send only 1 request to get both template and data ?
If I need send 2 requests in this case and suppose I have to load 5 templates in home page then I have to send another 5 requests to bind data (from database) to each template ?
You can use resolve in the route, that ill load the data and than load your template. You can check here for solution http://odetocode.com/blogs/scott/archive/2014/05/20/using-resolve-in-angularjs-routes.aspx
I'm using Ionic framework to build a hybrid mobile application and I have html5Mode set to true, Ui-Router, and gulp to provide me with livereload, sass compiling, css and javascript minifying.
The problem is whenever I navigate to a state directly from the index, everything works fine, requests are being made to my server, but when I refresh that same state, I get Cannot GET error.
I am treating my Ionic application as a separate thing from my Express.JS app.
Here's some code:
States
$stateProvider
.state('faculties', {
url: '/',
templateUrl: 'views/main/main.html',
controller: 'MainCtrl as main'
})
.state('faculty', {
url: 'faculties/:faculty',
templateUrl: 'views/faculty/faculty.html',
controller: 'FacultyCtrl as v'
})
So, if I opened the page and clicked on the button that takes me to the 'faculty' state, It's all good. But if I refresh that page, it's giving me that Cannot GET error.
Here's the code from the 'faculty' state controller:
app.controller('FacultyCtrl', function ($http, $stateParams, appConfig) {
var v = this;
var api = appConfig.api;
v.faculty = {};
$http.get( api + '/faculties/' + $stateParams.faculty)
.then( res => {
v.faculty = res.data;
}).catch( error => {
console.log(error);
});
});
The problem you are having is that you do not route all possible urls to the same index.html
When you first load the page, say, the URL being http://example.com/, your web server will serve the static file index.html from your root. When changing the route, your URL ends up as (for example) http://example.com/some_page. This works because the URL is "faked", there is no such file on the server. When refreshing (or going to that URL directly), that URL is requested from the server, which fails (since, as before, that file/folder does not exist).
What you need to do is route all requests (excluding API and whatnot) to the same static index.html, this is standard behavior of all single-page apps:
The routing is done clientside.
I am stuck with this strange behaviour. None of the Google hits seem to return any mention of a similar case so I am assuming that I am doing something seriously wrong.
My interceptor does react on the 401 status and redirects to the appropriate route but at the same time it renders the previous route too. So I have a very ugly flash of one template then the other. I am simply trying to test my authentication: if authenticated then render the table, otherwise render the login form. It does redirect to the login form but still flashes the table template for a fraction of a second.
angular.module('Basal', ['ngRoute', 'Basal.users'])
.config(function($routeProvider, $locationProvider, $httpProvider) {
$locationProvider.html5Mode(true);
$httpProvider.interceptors.push('authInterceptor');
$routeProvider.
when('/', {
templateUrl: '/tpl/table.html',
controller: 'MainCtrl'
}).
when('/login', {
templateUrl: '/tpl/login-form.html',
controller: 'MainCtrl'
}).
otherwise({
redirectTo: '/'
});
});
angular.module('Basal.users', [])
.controller('MainCtrl', function($scope, getJson) {
getJson.fetch(function (d){
$scope.computers = d;
});
})
.factory('getJson', function($http, $location) {
return {
fetch: function (c) {
$http.get("/json")
.success(function(data) {
console.log("getJson: Success!");
c(data);
})
.error(function() {
console.log("getJson: Failure!");
});
}
}
})
.factory('authInterceptor', function($q, $location) {
return {
'responseError': function(response) {
if (response.status === 401) {
$location.path('/login');
}
return $q.reject(response);
}
}
});
Now, when I hit '/' on the browser Angular does two requests on the background: one is to fetch the table template and insert it in to the view and the other is to get the JSON data.
On the server side I put session restriction only on the data request! The template is just a static file. To put restriction on the template I need to drag it through the server routing and this is not, I believe, how Angular does things. But if I do create server side route for the template and put session restriction on it then double rendering disappears.
I am confused about how this works. Fetching the template and fetching the data is done asynchronously in parallel. So while JSON request triggers 401 and redirects to the login template, the original table template is still going through and being rendered empty. Hence I get all the ugly double rendering. This is a race of some kind. How do I stop it? Maybe my interceptor is wrong? Isn't the Angular interceptor supposed to stop any further processing?
As a related issue, the otherwise function on the $routeProvider does not work either. If I put a non-existent URL, I get 404 from the server but Angular routing does not catch it. Is this how it is supposed to be? If a URL change happens in Angular and then I hit reload on the browser, I get an ugly 404 instead of a nice redirect. Am I supposed to handle 404 in an interceptor too? Then what is the point of otherwise?
Thanks.
I am at a total loss with what's wrong with how I've setup my nested views. What am I doing wrong???
app.config(function ($stateProvider, $urlRouterProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$stateProvider
.state('main', {
url: '/',
template: '<div><h1>Hello World</h1><div ui-view></div></div>',
controller: 'MainCtrl'
})
.state('main.test', {
template: '<div><h2>I\'m here!</h2></div>',
url: '/here'
});
});
What happens is I go to / and it shows me "Hello World", and then I go to /here and it shows me a blank page. I'm not sure what I'm doing wrong...
You need to omit the preceding / in url:
.state('main.test', {
template: '<div><h2>I\'m here!</h2></div>',
url: 'here'
});
debugging
when clicking on this anchor ui-router navigates to this location: http://localhost:8000//here
<a ui-sref="main.test">test</a>
In your application you can easily check the url of a state
app.run(function($state){
var href = $state.href('main.test');
console.log(href); # '//here'
});
Be sure to set the server to support html5mode
$location documantation
Server side
Using this mode requires URL rewriting on server side, basically you have to rewrite all your links to entry point of your
application (e.g. index.html)
