angularjs - Can I manage dynamic controllers based on $stateParams? -

-

i'm working ui-router. know of set dynamic templateurl i'd manage dynamic controller.

here i'm looking for:

$stateprovider.state('town.building', {     url: "/building?id",     templateurl: function ($stateparams) { // working dynamic templateurl         if ($stateparams.hasownproperty('id')) {             switch (number($stateparams.id)) {             case 1:                 return "views/factory.html";             /* case 2, case 3, etc. */             default:                 return null;             }         }         return null;     },     controller: function ($stateparams) { // dynamic controller ?         if ($stateparams.hasownproperty('id')) {             switch (number($stateparams.id)) {             case 1:                 return "myfirstcontroller";             /* case 2, case 3, etc. */             default:                 return "defaultcontroller";             }         }         return null;     } });

is possible ? going wrong way ?

this do: 

$stateprovider      .state('intermediary-state', {               url:     '/',               onenter: ['$stateparams', '$state',                 function ($stateparams, $state) {                   if ($stateparams.id === '1') {                     $state.go('somewhere');                   } else {                     $state.go('somewhere-else');                   }                 }]             })      .state('somewhere', {               url:     '/somewhere',               controller: 'somewherectrl'             })      .state('somewhere-else', {               url:     '/somewhere-else',               controller: 'somewhereelsectrl'             });

the logic behind i'm using intermediary state grabs stateparams, evaluates , redirects accordingly.

this being said, i'm not sure why need controllers dynamic based on stateparams. seems code smell me well, , better option depend on underlying service.

for example might have different "home" state/controller logged in user versus guest user, , authenticationservice responsible of logic.

$stateprovider      .state('intermediary-state', {               url:     '/',               onenter: ['authenticationservice', '$state',                 function (authenticationservice, $state) {                   if (authenticationservice.isloggedin()) {                     $state.go('home-user');                   } else {                     $state.go('home-guest');                   }                 }]             })
