Controller being called twice in Ionic (AngularJS)

问题

In my angular project the user accepts a EULA then get automatically redirected to their dashboard, however, on this redirect the DashboardController seems to be being called twice, the DashboardController is being called on the route itself, I have checked to see if I have accidently called it again in the template but I havn't. Below is my route & controller. It doesn't appear to matter if I access the URL directly or via the redirect on the EULA controller, I get the same result.

The routes

.config(function($httpProvider, $stateProvider, $urlRouterProvider) {

    $httpProvider.interceptors.push('httpRequestInterceptor');

    $urlRouterProvider.otherwise('/');

    $stateProvider

    .state('login', {
        url: '/',
        templateUrl: 'templates/login.html',
        data: {
            requireLogin: false
        }
    })
    .state('eula', {
        url: '/eula',
        templateUrl: 'templates/eula.html',
        data: {
            requireLogin: true
        }
    })
    .state('dashboard', {
        url: '/groups',
        templateUrl: 'templates/dashboard.html',
        data: {
            requireLogin: true
        }
    })
});

The controller:

App.controller('DashboardController', ['$scope', 'RequestService', '$state', '$rootScope', function($scope, RequestService, $state, $rootScope){

alert('test');

}]);

Any ideas?

If you are using ui-router you don't have to use ng-controller. You have used it in your dashboard.html, another is generated by ui-router - that's why it is hit twice.

Ok so after a long time debugging and check stuff out, I found out that it was an issue relating to the Nav Bar in ionic, essentially, I was calling <ui-view></ui-view> & <ion-nav-view></ion-nav-view> on the same page, so basically doubling up on my views which in turn was calling the controller twice.

I know this has been answered already as well, but I wanted to add my fix for the exact same problem.

My controllers were also being called twice, but in my case I had to comment out the ng-controller settings in various files:

My config function in the main app.js

.config(function($stateProvider, $urlRouterProvider) {
    $stateProvider
        .state('splash', {
            url: "/",
            templateUrl: "app/splash/splash.html"
            // controller: 'SplashCtrl'
        })

Since I was already calling it in the markup:

<ion-view view-title="TickerTags" ng-controller="SplashCtrl as splash">
    <ion-content class="splash">

The controller key inside of my Directives

angular
    .module('tagsPanelDirective', [])
    .controller('TagsPanelCtrl', TagsPanelCtrl)
    .directive('tagsPanel', tagsPanel);

function tagsPanel() {
    var directive = {
        templateUrl: "app/tags/tagsPanel.html",
        restrict: "E",
        replace: true,
        bindToController: true,
        // controller: 'TagsPanelCtrl as tagsPanel',
        link: link,
        scope: false
    };
    return directive;
    function link(scope, element, attrs) {}
}

Again since I was already calling it from within the template markup:

<section class="tags-panel" ng-controller="TagsPanelCtrl as tagsPanel">
