Angular Redirect when url has no parameters - angularjs

When user lost password, an email is sent to his account with an URL. I want the page that controls a reset password only loads if the url has a parameter. Im using Angular.
For example:
if user goes to http://example.com/reset_password/A232Ddade
loads the reset_password/reset_password.html page normally
but
if user goes to http://example.com/reset_password/
redirect to http://example.com/index.html
Another thing to consider is that before rendering the page, I will use the parameter to find the user that will change the password.
To make this happens I have to use some initialize function, read the parameter and if it is present use it or if it is not present redirect to index page? like
//At the top of the controller
var init = function () {
//check if there is query in url
//and redirect if not
};
//and fire it after definition
init();
Or Can I use the ui-router module?
Thanks.

It's look like standard usage of $routeProvider
app.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/reset_password/:param', {templateUrl: 'pageToReset.html', controller: ResetLogicCtrl}).
when('/reset_password/', {templateUrl: 'index.html', controller: IndexCtrl}).
otherwise({redirectTo: '/'});
}]);

You can do that with Resolve, on your route. Take the param and get the user with it, if there is no user, or if param is falsy value, redirect to wherever you want. That way your controller gets the needed data or it redirects.

$location.path or $location.url doesn't trigger the ngRoute controller

I have a route defines as follows:
$routeProvider.
when('/projects/', {
controller: 'ProjectCtrl',
controllerAs: 'project_ctrl',
templateUrl: '/static/app/partials/project.html'
}).
After the login finishes I need the user to land on this link, hence in my controller I am using this:
vm.login = function(form) {
if (form.$valid) {
loginService.login(vm.loginFormData.username, vm.loginFormData.password);
loginService.setUpUser()
$location.url("/projects");
}
}
But unfortunately the controller associated with this view is not triggered, that is ProjectCtrl is not triggered. However when I click on the navigation link which uses in the dom, it works fine. Can someone please guide me here, may I am missing something conceptual.
Hence the larger question is how do I redirect a user in the controller using some APIs which also complies with ngRoute based controllers.
Try removing the last / in url so it matches $location.url("/projects");
$routeProvider.
when('/projects', {

Angularjs route not calling the corresponding route's controller/view

I have an Angulrjs application and in the app.js I have the following config like below:
.config(function ($routeProvider, $locationProvider, $httpProvider) {
$routeProvider
.otherwise({
redirectTo: '/'
});
I am using ng-route and in my app.js run function I call a backend API which redirects me to a login page and once I enter my credentials it calls back the UI on the following address
http://hostname.company.net/?token=24OzjW%2FKZVfkiV%2Bku22T0ag%3D%3D
Now the page is blank instead of routing to the /. I have mapped the / with MainController but the controller and view is not getting mapped. If I print the $location.path the value is /.
Even if I reload the screen, the page is blank. Only when I remove the ?token=... and hit refresh I am getting the screen.
If I change the url to anything else, then it is working fine. If the route is a valid url, then corresponding controllers/view is called else MainController/MainView is getting called.
My config entry for handling the / is like below:
$routeProvider
.when('/', {
templateUrl: 'app/main/main.html',
controller: 'MainCtrl',
resolve: {
message: function (authService) {
return authService.authenticateUser();
}
}
});
Please let me know where I am going wrong or how to proceed as I am completely clueless on this bug.

Angularjs routing with variable appended

Basically, this is a social sort of application that I am working on.
So, for this app to work, the '/home' state shows a list of users. The 'friends/X' (X being user id) shows the profile of that user.
So, here is my app with the ng controller in the element:
ng-click="profile({{friend.id}})"
This hooks up and sends a function call to my controller "HomeController" which is currently in "/home". My problem is, how do I open a new state and pass a variable, the friend.id in this case to the state?
Thank you :)
EDIT:
Basically I want to know how a function "profile" can capture the id, then call the new state and send it the variable id of friend.id
EDIT 2:
Basically, in the profile function which is in the "HomeController" it will accept a ID as a perameter, so for example "1", and it will use the value it received and send the application to a NEW state for example now the new state is going to be "ProfileController" and it will be "/home/profile" or something like that, and it will pass along the "1" into the url, like so: "/home/profile/1".
If you want to do this inside a function, you should use the $location service to change the URL. Then the route will update, and the profile controller can take over.
<a ng-click="profile(friend.id)">{{friend.name}}</a>
... And in the controller:
$scope.profile = function(id) {
$location.url('/home/profile/' + id);
};
However, unless you need to do something with the click before changing the route, you can probably just do it with an href:
<a ng-href="#/home/profile/{{friend.id}}">{{friend.name}}</a>
If you stick to this method and leave it to the routing mechanism to choose the right controller, then your user will be able to copy/bookmark/jump to that URL directly, and use the back/forward buttons in the browser.
Use the $routeProvider service to tell AngularJS which controller to use based on the URL. For example (this should go in your module's .config):
$routeProvider
.when('/home/profile/:friendId', {
templateUrl: 'profile.html',
controller: 'ProfileController'
})
...etc
Then you can use $routeParams in ProfileController to get the current friendId parameter.

AngularJS: Checking if user is on a specific route that uses params

If I have a route as such:
$routeProvider.when('/event/:id', { templateUrl: 'view/event-details.html', controller: 'EventDetailCtrl'});
Is there a way to check if the user is on the /event/:id route
Is using if ($location.path().indexOf('/event/') !== -1) a safe way to check if the user is on this route?
Of course there is. Either you can use a console.log in controller or another way you can use an ng-init in the template URL to call any function. So if the template is loaded then it will call the function and hence you get to know that the user is on that route :)
I'm not sure to fully understand what you want to achieve. Your $routeProvider relays your incoming request to a particular controller. It is inside the controller you can fully access the tokens parsed by your $routeProvider.
Declare $routeParams in your controller to access the tokens of your matched route.
$routeProvider
.when('/event/:id', { templateUrl: 'view/event-details.html', controller: 'EventDetailCtrl'});
In your controller:
.controller('EventDetailCtrl', function($scope, $routeParams) {
$scope.id = $routeParams.id;
})

Check if user is logged in before template load

I use angularjs with ui-router library. Lets say I have some routes for admin and some routes for user. If admin or user is logged in I want to show some page for them (admin.html for admin and user.html for user, for example), otherwise login.html
On the backend I have a special url, like /auth/status/, which gives me information about the user (if he's logged and which role he has)
There are some situations I can't figure out how to handle:
I go to '/' url. The application loads. I have a run method for my app module. But how can I check if the user is logged in, when it happens asynchronously? Well, I have this and it works somehow, but I'm not sure if this is a good solution:
app.config(['$stateProvider', '$routeProvider',
function($stateProvider, $routeProvider) {
$stateProvider
.state('admin', {
abstract: true,
url: '/',
templateUrl: 'templates/admin.html'
})
.state('admin.desktop', {
url: 'desktop',
templateUrl: 'templates/desktop.html'
});
}]);
app.run([
'$http',
'$rootScope',
'$location',
'$state',
'userRoles',
function($http, $rootScope, $location, $state, userRoles) {
var DEFAULT_ADMIN_STATE = 'admin.desktop';
var promise = $http.get('/auth/status/');
promise.then(function(response) {
$rootScope.isLogged = response.data.logged;
$rootScope.userRole = userRoles[response.data.role];
if (!$rootScope.isLogged) {
$state.transitionTo('login');
} else {
switch (response.data.role) {
case 'admin': $state.transitionTo(DEFAULT_ADMIN_STATE); break;
}
}
}, function(response) {
$location.path('/login');
});
}]);
Though I don't understand: if I go to / url I should get an error because it's abstract. Instead when $http.get request is resolved (I put 2 seconds sleep in backend to check that) I transition to admin.desktop state. I'm confused what happens in which order: state loads template or app.run function with some ajax requests...
The main question is, when I go to /#/desktop how can I first check if user is logged (send a request to /admin/auth/ and check what it returns) and only then decide what to do (transition to login or desktop state)?
I found Delaying AngularJS route change until model loaded to prevent flicker this, but again still a little fuzzy for me. Resolve property seems like a solution when I want to load a list of entities and then show the template. But I want to have some "before" function for ALL states which just checks if user is logged and has a correspond role (one moment: I do not want to use /admin/entites or /user/entities urls, want to have just /entitites. As I get it several states may have the same url). So basically it looks like if I go to /someurl I want to run method wait until it gets ajax response and after that transition to some state. Instead the state corresponding to /someurl load a template...
Also I found an article about authentication in angular but author uses cookies which is not async thing
Update: when I use cookies for checking if user is logged and I go to /#/desktop I still have it rendered, and $state.transitionTo doesn't work..
You should check it before page load:
I cannot write full example now, but in common you should do like this:
.run([ ..., function(....) {
$scope.$on('$routeChangeStart', function(next, current) {
... check cookie here ...
});
}]);
