Mean JS stack, create a factory that handles two different paths

Question

I am using the MEAN JS framework and pretty much everything that came with it. However, I am trying to add a custom query when a user goes to a specific path (url). This is the code that came with MEAN JS: (in modules/articles/client/services)

'use strict';

//Articles service used for communicating with the articles REST endpoints
angular.module('articles').factory('Articles', ['$resource',
  function ($resource) {
    return $resource('api/articles/:articleId', {
      articleId: '@_id'
    }, {
      update: {
        method: 'PUT'
      }
    });
  }
]);

And this takes care of all the functions defined in the controller, which are: create, update, find, findOne, remove. Now I am trying to add another function, $scope.findByCategory = function (category) {...} in the controller. But in order for it to communicate with the server, I need to add the path to the services.

How do I do that? How do I edit my service (or factory) so it takes care for all the functions that I define in my controller. ( I have already set up the routes in the server side.) Said in other words, I want to combine the above code and the below code into one piece in my client service. Note: the only thing changing is the path.

//Articles service used for communicating with the articles REST endpoints
angular.module('articles').factory('Articles', ['$resource',
  function ($resource) {
    return $resource('api/articles/category', {
      articleId: '@_id'
    }, {
      update: {
        method: 'PUT'
      }
    });
  }
]);

There are multiple way to do it, you could do another factory called Category or you can use the same returning an object like this:

angular.module('articles').factory('Articles', ['$resource',
    function($resource) {
        return {
            articles: $resource('api/articles/:articleId', {
                articleId: '@_id'
            }, {
                update: {
                    method: 'PUT'
                }
            }),
            categories: $resource('api/articles/:articleId/category', {
                articleId: '@_id'
            }, {
                update: {
                    method: 'PUT'
                }
            })
        };
    };
]);

You will call them from a controller with for example Articles.articles.get() and Articles.categories.get()

And probably you want to change the category route to api/articles/:articleId/category so it get categories for the articleId
