Is it possible to pass only templateUrl in $routeProvider.when() - angularjs

Can we do something like this?
GuitarApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/list', {
templateUrl: 'partials/list.html',
<!-- no controller here -->
}).
when('/details/:guitarID', {
templateUrl: 'partials/details.html',
controller: 'DetailsController'
}).
otherwise({
redirectTo: '/list'
});
}]);
Beacause the controller that needed there is already added in tag of HTML, beacause other portion of HTML also want to make of that controller.

Specifying the controller in $routeProvider is completely optional. Just be sure your HTML specifies it. And be sure that you don't have it in both places!
As comments mentioned, refer to best practices on what is 'best' to do.

otherwise redirectTo does not work

trying to set the default route when it fails but for some reason it does not work with my SPA.
here is the current code
app.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'templates/index.html',
controller: 'IndexCtrl'
})
.otherwise({
redirectTo: '/'
});
});
also tried to change otherwise to
.otherwise({
redirecTo: function(){
return '/'
}
});
on the other hand if I put template url within otherwise it works
.otherwise({
templateUrl: 'templates/index.html',
controller: 'IndexCtrl'
});
really don't understand why it behaves differently !?
I edited one of my ng-Route tests to essentially have the same setup as your when('/') and otherwise methods, but mine is working just fine:
https://codepen.io/tcraw/pen/vRpOXz
The only thing I can think of at this point is that perhaps your templateUrl is incorrect...
Do you have another view to test in the templates directory? (e.g. templates/otherView.html)

Controllers and how they should be implemented in Angular?

Sorry if this seems like a stupid or simple question but I am a little confused, I have been looking up many different kinds of tutorials for Angular to understand the concept and how to create an application.
The issue is how to you attach a Controller to the Page, I have seen two methods:
Add the controller script to the page
Display Controller inside the app.js where the Website Routing is.
Here is what I have at the moment please let me know if there is any issues in this code:
var app = angular.module('myApp', [
'ngRoute'
]);
app.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'partials/home.html',
controller: 'homeController'
}).
when('/login', {
templateUrl: 'partials/login.html',
controller: ''
}).
when('/signup', {
templateUrl: 'partials/signup.html',
controller: ''
}).
when('/dashboard', {
templateUrl: 'partials/dashboard.html',
controller: ''
}).
otherwise({
redirectTo: '/404',
templateUrl: 'partials/404.html'
});
}]);
app.controller('homeController', ['$scope', function($scope) {
$scope.message = "This is the Home Page";
}]);
Again I am really new to Angular.
Updated to single Controller file:
app.js:
var app = angular.module('myApp', [
'ngRoute'
]);
app.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'partials/home.html',
controller: 'controllers/homeController.js'
}).
when('/login', {
templateUrl: 'partials/login.html',
controller: ''
}).
when('/signup', {
templateUrl: 'partials/signup.html',
controller: ''
}).
when('/dashboard', {
templateUrl: 'partials/dashboard.html',
controller: ''
}).
otherwise({
redirectTo: '/404',
templateUrl: 'partials/404.html'
});
}]);
controller file:
app.controller('homeController', ['$scope', function($scope) {
$scope.message = "This is the Home Page";
}]);
Nope, your code is fine. I generally use two different files app.js for all the routing options and a controller.js file for the different controllers. A single file seems a bit too cluttered to me.
A single file per controller works but I see for most usercases it turns out just a few lines of code per page for me, but you can if you have extensive codes in each controller
I create a Controller for every model in my database: e.g: ProjectController.js, PeopleController.js, etc. And I use app.js just for routing and general controllers like header, footer, etc.
There isn't a strict way to do it, you have to decide it based on your architecture design. But i can give you a tip: Never define your controllers in your .html file because it makes it awful and less readable.
That's a purely organizational choice. As long as the browser has the code of the controller available, it doesn't matter.
But unless you're creating a tiny demo, having all the controllers defined in a single JavaScript file will quickly become unmanageable: the file will be too large, you'll search for the controllers constantly, and everyone in the team will modify the same file, leading to conflicts, etc.
The simple rule is: one JS file per AngularJS component.
If you're concerned about two many JS files having to be loaded by the HTML page in production, then make sure to learn using gulp or grunt, and to generate a single minified JS file from all the small JS files used during development.
EDIT:
the controller attribute of the route is not supposed to be the path of a JS file. It's supposed to be the name of a controller. It should thus stay exactly as it was in the first, working example.
You need to understand how the browser works: if the HTML contains two <script> elements, it works the same way as if it had a single one with the code of the two scripts concatenated. So splitting the code in two files doesn't change the way the code is written.
Change your route specification to the following code:
app.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'partials/home.html',
controller: 'homeController' //change here
//controller should be the name of the controller,
//not the file containing the controller function
}).
when('/login', {
templateUrl: 'partials/login.html',
controller: ''
}).
when('/signup', {
templateUrl: 'partials/signup.html',
controller: ''
}).
when('/dashboard', {
templateUrl: 'partials/dashboard.html',
controller: ''
}).
otherwise({
redirectTo: '/404',
templateUrl: 'partials/404.html'
});
}]);

AngularJS: $routeProvider with multiple variables in URL

So I'm playing around with learning angular and trying to make a project issue tracker, only I'm having problems with ngRoute and routing.
What I'd ideally like is a system whereby (say) issuetrack.com/projectX returns a view of all the issues for projectX, and issuetrack.com/projectX/XYZ returns a view of the specific issue with the related ID (XYZ).
I've setup my config as such:
tracker.config(['$routeProvider', '$locationProvider',
function($routeProvider, $locationProvider) {
$routeProvider.
when('/', {
templateUrl: 'static/partials/index_partial.html',
}).
when('/dashboard', {
templateUrl: 'static/partials/dashboard.html',
controller: 'DashboardController'
}).
when('/404', {
templateUrl: 'static/partials/fourOHNOfour.html',
}).
when('/:project', {
templateUrl: 'static/partials/project.html',
controller: 'ProjectController'
}).
when('/:project/:issue', {
templateUrl: 'static/partials/issue.html',
controller: 'IssueController'
}).
otherwise({
redirectTo: '/404'
});
$locationProvider.html5Mode(true);
}]);
But every time I visit (say) localhost:8080/example/1 the page just hangs and becomes unresponsive. localhost:8080/example works completely fine though.
Is what I've done the right way to go about it, or is there another way my googling hasn't been able to find?
Thanks!
Fixed! After several hours...
All you need is:
<base href="/" />
In the head of the index page where the ng-view is.

It it possible to use ngroute to pull different html pages (not partials)?

Hopefully I can explain this properly. On the Angular tutorial, you can use partials doing this:
phonecatApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/phones', {
templateUrl: 'partials/phone-list.html',
controller: 'PhoneListCtrl'
}).
when('/phones/:phoneId', {
templateUrl: 'partials/phone-detail.html',
controller: 'PhoneDetailCtrl'
}).
otherwise({
redirectTo: '/phones'
});
}]);
We've all done it and it works great, but for the first time I'm using a different login.html page that doesn't have anything in common with the rest of the pages. Is there a way I can use ngRoute to setup the controller and just load the entire login.html page instead of pointing it at a partial?

AngularJS nested routing

I'm working a fairly simple AngularJS project with some deep route nesting to select from a nested data structure:
angular.module('doccat', []).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/', { templateUrl: 'partials/detail.html', controller: DocDetailCtrl }).
when('/:p0', { templateUrl: 'partials/detail.html', controller: DocDetailCtrl }).
when('/:p0/:p1', { templateUrl: 'partials/detail.html', controller: DocDetailCtrl }).
when('/:p0/:p1/:p2', { templateUrl: 'partials/detail.html', controller: DocDetailCtrl }).
when('/:p0/:p1/:p2/:p3', { templateUrl: 'partials/detail.html', controller: DocDetailCtrl }).
when('/:p0/:p1/:p2/:p3/:p4', { templateUrl: 'partials/detail.html', controller: DocDetailCtrl }).
otherwise({ redirectTo: '/' });
}]);
function DocDetailCtrl($scope, $routeParams) {
var path = [];
if ($routeParams.p0) path.push($routeParams.p0);
if ($routeParams.p1) path.push($routeParams.p1);
if ($routeParams.p2) path.push($routeParams.p2);
if ($routeParams.p3) path.push($routeParams.p3);
if ($routeParams.p4) path.push($routeParams.p4);
// do stuff with path
}
This has up to 5 layers in the path, which should be plenty for my purposes, so it is good enough for now. However, the underlying data could be nested arbitrarily deep, which would require arbitrary routing.
I think the ideal for this would be a route that says 'all the rest of the path goes to any array of parameters', but it doesn't look like there is a way to do anything like that in AngularJS. Just for the sake of completeness, does anyone know of a way to do this?
Check $routeProvider in the doc
angularjs $routeProvider.
Especially, in the definition of 'when', you can read: "path can contain named groups starting with a star (*name). All characters are eagerly stored in $routeParams under the given name when the route matches." So you just need to make sure the route matches and you'll get plenty parameters stored in $routeParams.
I hope it helps.
