modifying $route templateUrl based on locale - angularjs

I want to modify the templateUrl of a route definition, and make it dependant on the locale of the user.
E.g. '/views/en/faq.html' for English and '/views/fr/faq.html' for French users.
I have the locale stored in the cookie LOCALE, but how can I access that cookie value in the templateUrl function, as $cookies is not available yet while running the config function?

U can use angular translate service. This does this automatically.
Link https://github.com/angular-translate/angular-translate

In your case make two state, and put in tamplateurl '/views/fr/faq.html' for frach and for '/views/en/faq.html' for English
$stateProvider
.state('enFaq', {
url: "/Faq",
templateUrl: "/views/en/faq.html"
})
.state('frFaq', {
url: "/Faq",
templateUrl: "/views/fr/faq.html"
})
});
Acccording your condition you can hide one state
like
<a ui-sref="frFaq" ng-if="location=='fr'">Faq</a>
<a ui-sref="enFaq" ng-if="location='en'">Faq</a>

passing parameters in nested views with ui-router

I am running into trouble understanding how you can correctly pass parameters using AngularJS.
This is the code I was trying to use in my app.js file for the nested views, however, the nest state never properly renders.
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('news', {
url: '/news',
templateUrl: 'templates/news.html',
controller: 'NewsCtrl'
})
.state('news.id', {
url: '/news/:id',
templateUrl: 'templates/news.id.html',
controller: 'NewsCtrl'
});
// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/news');
})
It will try and change the url to #/news/news/:id versus just #/news/:id.
And if I try and change the path to just be the #/news/:id, then the pages do not render correctly.
What is the best approach to achieve these nested views with parameters?
According to ui-route wiki:
When using url routing together with nested states the default
behavior is for child states to append their url to the urls of each
of its parent states.
If you want to have absolute url matching, then you need to prefix
your url string with a special symbol '^'.
So in your case, you should try
.state('news.id', {
url: '^/news/:id',
templateUrl: 'templates/news.id.html',
controller: 'NewsCtrl'
});

AngularJS - Default view in <ui-view> element

Is there any problem putting default code inside of a <ui-view> element. It appears to work, but I can't find anything saying one way or another if it's okay to use or not.
My current usage is I want the "default" view to be a list of items. Upon clicking one of those items, it switches to an "editor" child state, which replaces the <ui-view> content with the editor child.
Are there any gotchas I should be aware of before continuing with this approach?
Here is an example of what I'm looking at:
routes.js:
.config(($stateProvider) => {
$stateProvider
.state('admin', {
url: '/admin',
templateUrl: 'admin.html'
})
.state('admin.items', {
url: '/admin/items',
templateUrl: 'admin.items.html'
})
});
admin.html:
<ui-view>Default Stuff Here</ui-view>
items.html:
<p ng-repeat="item in items">{{item}}</p>
Now, I know I can do:
.state('admin.default', {
url: '',
templateUrl: 'admin.default.html'
});
And then put that would show in ui-view. However, that needlessly adds a new state and template file, when it seems to work just fine putting the would-be contents of admin.default.html directly into the ui-view of admin.html.
In my case, I'm not talking about a completely stateless option using otherwise(), I'm talking about a defined parent state with a default child state.
We generally do not put anything inside <ui-view></ui-view>, instead we create a default state and use that.
routerApp.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/home');
$stateProvider
.state('home', {
url: '/home',
templateUrl: 'home.html'
})
.state('about', {
// we'll get to this in a bit
});
});
Here the default one is /home, like that you can create a default one.
First, As said in the other answer, we never give any data within the ui-view.. But while dealing with the ui-router, you should give all the specific states in .config()
app.config(function($stateProvider,$urlRouterProvider){
$stateProvider
.state('home',{
url : '/home',
controller: 'homeCtrl',
templateUrl : 'home.html'
}).state('login',{
url : '/login',
controller: 'loginCtrl',
templateUrl : 'login.html'
});
//AND HERE YOU PROVIDE THE DEFAULT PLACE WHERE THE USER IS TO BE REDIRECTED
//IN CASE OF IMPROPER URL
$urlRouterProvider.otherwise('/login');
});
Secondly, If you want to use the <ui-view></ui-view> to hold some data, you certainly can put some data within them.. But make sure that from the state you define, It should not supply any template or templateUrl. So the data within the <ui-view></ui-view> stays as it is.
And third.. Why to keep a default state..
in case you are defining a state admin in your config(), and then in your admin.routes.js file you can define a state as follows..
.state('admin.login',{
url:'',
controller:'loginCtrl',
templateUrl:'admin.login.html'
});
So in case the url is YOURURL/admin It will directly open the login page by default.. so there is no chance of redundancy...

Angular UI router dynamically inject URL to html

I am trying to build a simple app, which goes the following way:
I have 2 menu items in the navbar: home and contact.
The home should be a unique URL only once from the server, at initialisation, read from a QR code (i got this covered, that is no problem to me) and the contact should always be the same.
I got the contact done in the following way:
$stateProvider.state('contact', {
url: '/contact',
templateUrl: 'src/views/contact.html',
controller: 'contactController'
})
The problem is with the home, which should keep the unique URL received by the server. How should i write the state for that one?
.state('home', {
url: '/:uid',
templateUrl: 'src/views/home.html',
})
Also, the home should keep it's unique url generated by the server after refresh and while navigating from contact to home.
In the HTML i would have something like
<a ui-sref="home({uid: --some dynamic uid?--})">Home</a>
this is the part which also requires help.
Set the home state to
.state('home', {
url: /{uid},
templateUrl: 'src/views/home.html',
})
and you could grab the parameters by injecting $stateParams into the controller. $stateParams.uid would return the parameters and store that in local storage or cookies.
Check this link out
https://github.com/angular-ui/ui-router/wiki/URL-Routing#stateparams-service
UPDATE:
for example, this is the sample controller that is attached to the home page
app.controller('homeCtrl', function($stateParams) {
var id = $stateParams.uid; //this is how you retrieve the uid
});
by going to your home page e.g. http://www.example.com/abcd12345, the above $stateParams.uid would return abcd12345
Now to set the url. simply use ui-sref instead of href on the <a> tag. ui-router will automatically generate href for you.
e.g.
<a ui-sref="home({uid:'abcd12345'})">Home</a>
You have to create a custom provider and inject it into the config.
eg:- .config($stateProvider, $urlRouterProvider,yourprovider) .
I am not sure about this. But please check this way too..

Angularjs ui-router - pass extras 'unplanned' parameters

I have this simple state :
.state('search', {
url: '/search',
templateUrl: 'views/search.html',
controller: 'search'
})
And I would like to pass any extra unplanned parameters to the controller when using search state or /search route :
ui-sref="search({foo:1, bar:2})"
// would call '#/search?foo=1&bar2',
// match the state and pass foo and bar to the controller (through $stateParams)
When I try this, it matches the otherwise of the router instead. :(
I've read a lot of solutions that imply to declare each parameter in the state:
.state('search', {
url: '/search?param1&param2&param3?...',
})
But I cannot do this as far as the parameters list is not really defined and changes all the time depending on searched content.
Is there a way to achieve this ? Or am I wrong somewhere ?
Thx.
EDIT : When I try to call directly this url : #/search?foo=1, the state search matches but the foo parameter never goes to $stateParams which is empty. I don't know how to get it in.
.state('search', {
params: ['param1','param2','param3'],
templateUrl: '...',
controller: '...'
});
ui-sref="search({param1:1, param2:2})"

How to switch to a ui-router state conditionally?

I am writing a CRUD app with AngularJS + UI Router.
I want to be able to parse the current location in the browser URL and determine if a ui-router state should be applicable for the current url.
In these sample routes, is there some way to do the if and unless clauses?
(url in browser address bar is http://example.com/notes/1/edit_me)
$stateProvider.state("root", {
url: "",
unless: $location.matches(/\edit_me/)
})
$stateProvider.state("edit", {
url: "/edit",
if: $location.matches(/\edit_me/)
//
})
UPDATE 1
The reason I want to do the above:
Say I am at http://example.com/notes. The routes is
$stateProvider.state("root", {
url: "",
})
However, with the same above ui.route state, when I am at url http://example.com/notes/edit, the root is now "/notes/edit" instead of "/notes"
UPDATE 2
#adam, more explanation of what I am trying to accomplish:
I will try to explain: in your code, for your home state, the (ui.router's) url is / (aka hash syntax #!/)
However, the URL in browser address bar looks like http://example.com/notes/ in one case and http://example.com/notes/edit in another case. (note that the URLs do not contain any #! portion since we have just navigated to the page)
Now the home's / is going to match in both cases of above URL.
But since the second URL ends in notes/edit, I want that the home for this URL should be #!/edit, and not #!/.
Basically I am trying to mix server-side rendered pages (/notes and /notes/edit are rendered by server, not AngularJS)
and client side routing so that no matter which URL we are at, the client can figure out which (ui.router) route applies to the current URL.
Make sense?
Sorry i don't really understand your needs but here's an example of use of ui-router:
$stateProvider
.state('home', {
url: '/',
templateUrl: 'app/main/index.html',
controller: 'MainCtrl'
})
$stateProvider
.state('edit', {
url: '/edit',
templateUrl: 'app/edit/edit.html',
controller: 'EditCtrl'
})
$stateProvider
.state('edit.note', {
url: '/note',
templateUrl: 'app/edit/note.html',
controller: 'NoteCtrl'
});
$urlRouterProvider.otherwise('/');
i'm not sure if a copy paste will work, but try to adapt it with your case. Hope it will help.
Edit:
I'm afraid that i can't help you more than that. The design of your app with rendered page without angular sounds really special.
Have you tried the example i provide you? If yes, hav you simply format the url by addind
" #!/ " where you need it.
For example:
$stateProvider
.state('edit', {
url: '#!/edit', //or something like, url:'/#!/edit'
templateUrl: 'app/edit/edit.html',
controller: 'EditCtrl'
});
