$resource transformResponse not working

Question

Got a simplified $resource example here (adapted from Angular site):

angular.module('project', ['mongolab']);

function ListCtrl($scope, Project) {
  $scope.projects = Project.test();
}

angular.module('mongolab', ['ngResource']).
factory('Project', function ($resource) {
  var url, dfParams, actions;

  url = 'https://api.mongolab.com/api/1/databases' + '/angularjs/collections/projects/:id';
  dfParams = {
    apiKey: '4f847ad3e4b08a2eed5f3b54'
  };

  actions = {
    test: {
      method: 'GET',
      isArray: true,
      transformResponse: function (response) {
        // line is never getting called
        console.log('transforming');
        return response;
      }
  };

  var Project = $resource(url, dfParams, actions);
  return Project;
});

The question is that the line console.log('transforming') is never getting called. Why is that? Everything else works fine.

Answer 1

This functionality is only available in the 1.1.2 or later versions of AngularJs. It is not available in the 1.1.1 or earlier versions of AngularJs.

Answer 2

Response transformation callback is not exposed in $resource service. It lives inside the underlying $http service.

So you have two choices:

• Use "low-level" $http instead of $resource abstraction,
• Create some kind of wrapper around your resource, which would transform the response the way you want.
