If you want to use asynchronous method you need to use callback function by  promise  here is example   var Regions    resource  mocks regions json      scope regions   Regions query     scope regions  promise then function  result         scope regions   result

You could also do   Regions query     function response         scope regions   response         Do stuff that depends on  scope regions here

If you re looking to get promise in resource call  you should use      Regions query    q then function              Update    the promise syntax is changed in current versions which reads  Regions query    promise then function              Those who have downvoted don t know what it was and who first added this promise to resource object  I used this feature in late 2012 - yes 2012
