angularjs how to avoid access to a just visited route - angularjs

Question

Put the case I've got a route like
.config(function (CONFIG,$routeProvider) {
$routeProvider
.when('/', {
templateUrl: CONFIG.site.path_views + '/index/index.html',
controller: 'IndexCtrl'
})
.when('/contestant/create', {
templateUrl: CONFIG.site.path_views + '/contestant/create.html',
controller: 'ContestantCreateCtrl'
})
.when('/contestant/thanks', {
templateUrl: CONFIG.site.path_views + '/contestant/thanks.html',
controller: 'ContestantThanksCtrl'
})
.when('/product', {
templateUrl: CONFIG.site.path_views + '/product/index.html',
controller: 'ProductCtrl'
})
.when('/prize', {
templateUrl: CONFIG.site.path_views + '/prize/index.html',
controller: 'PrizeCtrl'
})
.otherwise({
redirectTo: '/'
});
})
I'd like to deny access or simply redirect the user
to /contestant/create if he/she has filled in the form
but I don't find a way :(

app.run( function(VisitedRoutes) {
VisitedRoutes.init();
};
app.factory('VisitedRoutes', function($rootScope,$location) {
var routes = [];
return {
add : function(){
routes.push($location.path());
},
all:function(){
return _.uniq(routes);
},
hasRoute:function(value){
return _.indexOf(this.all(), value)
},
init:function(){
var that = this;
$rootScope.$on('$routeChangeSuccess', function (scope, next, current) {
that.add();
});
}
}
});
app.controller('ContestantCreateCtrl',function($scope,$location,VisitedRoutes) {
if(VisitedRoutes.hasRoute('/contestant/thanks') !== -1){
$location.path('/');
}
});
