javascript - angularjs $resource class-level callbacks, or post-processing -


i have $resource api return data needs cleaned before going presentation layer. specifically, it's .net returning date objects in lovely '/date(...)/' format.

i don't want have write callback every time call .query() or .get(). there way extend resource callback gets called upon rest methods update instance's properties, or adding sort of $watch gets fired when date property changes? happen every instance of $resource.

angular.module('myappservices', ['ngresource'])     .factory('participant', ['$resource', function ($resource) {         var res = $resource('api/url/participants/:id', { id: '@id' });          // doesn't work, kinda this?         res.prototype.$watch(this.fieldname, function(newval, oldval) {             if (needscleaning(newval.fieldname) {                 this.fieldname = cleanupfield(newval);             }         };     });

ah-ha, found way around , leave here. in version 1.1.2 added support passing $http.config options $resource. naturally, cdn i'm using doesn't have recent enough version of angular-resource.js, switching cdns solved that.

i used transformresponse option modify data comes back.

angular.module('myappservices', ['ngresource'])     .factory('participant', ['$resource', '$http', function ($resource, $http) {         var res = $resource('api/url/participants/:id', { id: '@id' }, {         save: {             method: 'post',             transformresponse: $http.defaults.transformresponse.concat([                 function (data, headersgetter) {                     data.fieldname = yourdateparsingfunction(data.fieldname);                      return data;                 }             ])         }     });

i'm adding transformer on $httpprovider's transformresponse, deserialization, etc.
