Original Question
I'm developing a mobile app using the Ionic Framework and AngularJS and I am having issues with controllers not reloading once they have been initialised.
One of the state transitions (from 'app.postbox-details'
to 'app.audit-questions'
) should pass a parameter to the 'app.audit-questions'
controller but this controller does not update itself with the new parameter because it isn't reloading.
Code Example
app.js file - config
angular.module('sf-maintenance', ['ionic', 'starter.controllers', 'starter.services', 'ngCordova'])
.config(function ($stateProvider, $urlRouterProvider, $httpProvider) {
$stateProvider
.state('home', {
url: '/home',
templateUrl: 'templates/home.html',
controller: 'HomeCtrl',
})
.state('app', { //app state being the side-menu
url: '/app',
abstract: true, //means that this state will never be activated directly, users will always go to a child state instead.
templateUrl: 'templates/side-menu.html',
controller: 'MenuCtrl'
})
.state('app.postbox-details', {
url: '/postbox-details',
views: {
'menuContent': {
templateUrl: 'templates/postbox-details.html',
controller: 'PostboxDetailsCtrl'
}
}
})
.state('app.audit-questions', {
url: '/audit-questions/:postboxGuid',
views: {
'menuContent': {
templateUrl: 'templates/audit-questions.html',
controller: 'AuditCtrl'
}
}
})
$urlRouterProvider.otherwise('/home');
});
controller.js file (left out the code that isn't relevant)
angular.module('starter.controllers', [])
.controller('HomeCtrl', function ($scope) {
})
.controller('MenuCtrl', function ($scope) {
})
.controller('PostboxDetailsCtrl', function ($scope, $ionicLoading, $ionicPopup, $cordovaBarcodeScanner, $state, DataService) {
$scope.postboxGuid = DataService.getNewGUID();
//Rest of the controller functions are below
})
.controller('AuditCtrl', function ($scope, $ionicSlideBoxDelegate, $stateParams, DataService) {
$scope.auditDetails = {
postboxGuid: $stateParams.postboxGuid
};
});
View - navigation code
The view code to perform the navigations all use <a>
tags:
- From the home view to the postbox-details view:
<a class="button button-block button-dark icon-right ion-chevron-right" href="#/app/postbox-details">New inspection</a>
- From the postbox-details view to audit-questions view:
<a class="button button-block button-dark icon-right ion-chevron-right" ng-click="saveFormData()" ng-href="#/app/audit-questions/{{postboxGuid}}">New audit</a>
So does anybody know how to get controllers to reload once it has been initialised or if I am going about this problem the wrong way could you guide me to a method that will work?
Updated Information
I recently saw a related question and the response by @Radim Köhler pointed to the answer in this question which provides good information on why it may not be a good idea to use cache:false
on a view because of performance.
I thought I would share this because in some situations you may benefit more performance-wise by using one of Ionic's built-in view life cycle events to run code without having to disable the view from being cached.
