json - Angularjs $resource and $http synchronous call? -

i want write 2 services 1 $http.get method , 1 $resource

this service should receive json object , looks this, @ moment code direct in controller , not in service:

 var csvpromise= $http.get(base_url + 'datasource/1').success(function(data) {      $scope.data4=json.stringify(data);  }); 

the problem is, want save received data in $scope.data4 , want use data after $http.get call value empty.

direct after call there , object needs value:

new myobject($scope.data4)  

so myobject must wait long until data has arrived.

or can make synchronous call $http or $resource ?

how can ? have found many examples promise , .then nothing has worked me.

edit: have written service didn`t work:

 var test=angular.module('myapp.getcsv', ['ngresource']);  test.factory('getcsv',function($log, $http,$q, $resource){      return {          getdata: function (id) {              var csvpromise= $http.get(base_url +'datasource/'+id)                  .success(function(data) {                  return data;              });                  return csvpromise;          }      }  }); 

and in controller call this:

 getcsv.getdata(1).then(function(thedata){          $scope.data4=json.stringify(thedata);          new myobject( $scope.data4); }); 

but did not work. thought if $http.get receives data then function called.

i don't believe can synchronous calls. said, have @ least 2 options:

1) pass in data using $routeprovider resolve feature. documentation:

an optional map of dependencies should injected controller. if of these dependencies promises, router wait them resolved or 1 rejected before controller instantiated. if promises resolved successfully, values of resolved promises injected

an example on how use this:

$routeprovider   .when('/your/path', {     templateurl: '/app/yourtemplate.html',     controller: 'yourcontroller',     resolve: {       data: ['$route', '$http', function($route, $http) {         return $http.get(base_url +'datasource/1');       }]     }   }) 

and in controller:

app.controller('yourcontroller', ['$scope', 'data', function($scope, data) {   $scope.data4 = json.stringufy(data);   var yourobj = new myobject($scope.data4); }]); 

2) second option use promises , instantiate new myobject($scope.data4) once promise completes.
