resources - Changing the URL/IP of angularjs ngresource in ionic -

i use user selected ip address change rest url more 1 time, may have serval server ip addresses, after factory file loaded after app start, ip addresses ($rootscope.baseurl) cannot changed.

is there anyway can change path again?

p.s. console.log("$rootscope.baseurl") can output value, after return part, not working.

controller:

$scope.authenticateuser = function(){       $rootscope.$broadcast('ipchanged', $scope.user.ip); } 

factory:

.factory( 'models', function ($rootscope, $resource, constants) {          $rootscope.$on('ipchanged', function(event, data) {             $rootscope.baseurl = "http://" + data + "/rest"             console.log("$rootscope.baseurl")         });       return{             appmaster_user_session: $resource($rootscope.baseurl + '/user/session',                 {                     app_name: constants.api.appname                 },                 {                     'post': {method:'post'},                     'put': {method: 'put'}                 }             ), 

you can make service configurable using provider recipe.

myapp.provider('models', function modelsprovider() {   var apiurl = 'http://www.deafault.com';    this.apiurl = function(value) {     apiurl = value;   };    this.$get = [function modelsfactory() {     return {         appmaster_user_session: $resource(apiurl  + '/user/session',             {                 app_name: constants.api.appname             },             {                 'post': {method:'post'},                 'put': {method: 'put'}             }         )      }   }]; }); 

you need set apiurl in config section of module.

if want different url each time make resource contain function recieves apiurl.

myapp.provider('models', function modelsprovider() {    this.$get = [function modelsfactory() {     return {         getsessionresource: function(apiurl) {           return $resource(apiurl  + '/user/session',             {                 app_name: constants.api.appname             },             {                 'post': {method:'post'},                 'put': {method: 'put'}             }         )      }   }]; });
