AngularJS: Creating Objects that map to REST Resources (ORM-Style)

Question

I\'m pretty new to AngularJS, but I\'m pretty unclear on how to tie it up to my Server\'s REST Api backend.

For example, say I have an \"image\" resource that I get by G

One more example of helper for ngResource. This relies on fact that the vast majority of services is something like that:

http://host/api/posts
http://host/api/posts/123
http://host/api/posts/123/comments
http://host/api/posts/123/comments/456

So, the task is to make a helper that create AngularJS resource objects that maps on such services. Here it is:

'use strict';

var api = angular.module('api', ['ngResource']);

// RESTful API helper
api.addService = function (serviceNameComponents) {
    var serviceName = "";
    var resource = "/api"; // Root for REST services
    var params = {};

    serviceNameComponents.forEach(function (serviceNameComponent) {
        serviceName += serviceNameComponent;

        var lowerCaseServiceNameComponent = serviceNameComponent.toLowerCase();
        var collection = lowerCaseServiceNameComponent + 's';
        var id = lowerCaseServiceNameComponent + 'Id';

        resource += "/" + collection + "/:" + id;
        params[id] = '@' + id;
    });

    this.factory(serviceName, ['$resource',
        function ($resource) {
            return $resource(resource, {}, {
                    query: {
                        method: 'GET',
                        params: params,
                        isArray: true
                    },
                    save: {
                        method: 'POST',
                    },
                    update: {
                        method: 'PUT',
                        params: params,
                    },
                    remove: {
                        method: 'DELETE',
                        params: params,
                    }
                }
            );
        }
    ]);
}

So, to use it simply call this helper

api.addService(["Post"]);
api.addService(["Post", "Comment"]);

And then you can use Post and PostComment in code with needed params like :post_id
