How can I extend the $http service in angular?

Question

Unfortunately, we're stuck running 1.2.26 (will upgrade to 1.2.28 when it's gemified).

In the meantime, how can I patch (heh) $http so that the short-hand patch method is available? I'm pretty new to the whole service/factory/module thing. I've done hours of searching and can't seem to figure it out.

myApp.factory('patchedHTTP', function($http, BasicService) {
  // $http['patch'] = function(url, data, config) {
  //   return $http(angular.extend(config || {}, {
  //     method: 'patch',
  //     url: url,
  //     data: data
  //   }));
  // };
  var extended = angular.extend(BasicService, {});
  extended.createShortMethodsWithData('patch');
  return extended;
});

Above is the best I've got... and it doesn't do anything XD

You can do this with an angular decorator.

A service decorator intercepts the creation of a service, allowing it to override or modify the behaviour of the service. The object returned by the decorator may be the original service, or a new service object which replaces or wraps and delegates to the original service. For more information you can check angular documentation.

Example:

var app = angular.module('app');
app.decorator('$http', function ($delegate) {
  // NOTE: $delegate is the original service

  $delegate.patch = function () {
    // do the implementation here
  };

  return $delegate;
});

// usage
app.controller('SomeController', function($http) {
    $http.patch();
});

You can keep this decorator until you upgrade to some newer version and than just safely delete it.
