I retrieve some datas from a server using rest
ServiceController
Info.controller('ServiceController', function ServiceController(
$scope, $http, $routeParams, manageDatas) {
$scope.serviceId = $routeParams.serviceId;
$scope.serviceName = $routeParams.serviceName ;
var paramsService = {
serviceId : $scope.serviceId,
serviceName : $scope.serviceName
};
$scope.loading = true;
var response = $http({
url : 'rest/service',
params : paramsService,
method : 'GET'
});
response.success(function(service) {
$scope.service = service;
$scope.loading = false;
manageDatas.setArrayData($scope.service.languageList); // service which allow to pass an array in LanguageController
});
});
LanguageController
LanguageController.controller('LanguageController', function ServiceByLanguageController(
$scope, $http, $routeParams, $timeout , manageDatas , $route) {
$scope.listLanguage = manageDatas.getDatas(); // retrieve the array passed in ServiceController by a service
// always null
});
The problem is the $http.success method in ServiceController is always executed AFTER LanguageController(verified by breakpoints) so the array $scope.listLanguage is always empty because i don t pass datas....
How can i make the languageController be executed after all the treatments in serviceController finish ?
Thank you very much

Answer 1

Alternatively, you can broadcast event in response.success(function(service) {...}, say, using $rootScope, and let LanguageController listen to this event and then do assignment $scope.listLanguage = ...

Answer 2

Just after a brief look, I would say that part or all of your ServicesController logic should be in a service and not a controller. You seem to have such a service in manageDatas. Just put all the code that actually loads and writes data to the service inside the service.
