在哪里放置资源的特定逻辑 [英] where to place resource specific logic

问题描述

您可以帮我请考虑在何处放置资源（服务）在AngularJS具体的业务逻辑。我觉得这应该是伟大的创造超过我的一些资源模特般的抽象，但我不知道怎么样。

Can you help me please to consider where to place resource (service) specific business logic in AngularJS. I feel it should be great to create some model-like abstraction over my resource, but I'm not sure how.

API调用：

> GET /customers/1
< {"first_name": "John", "last_name": "Doe", "created_at": '1342915200'}

资源（以CoffeScript）：

Resource (in CoffeScript):

services = angular.module('billing.services', ['ngResource'])
services.factory('CustomerService', ['$resource', ($resource) ->
  $resource('http://virtualmaster.apiary.io/customers/:id', {}, {
    all: {method: 'GET', params: {}},
    find: {method: 'GET', params: {}, isArray: true}
  })
])

我想要做的是这样的：

I'd like to do something like:

c = CustomerService.get(1)
c.full_name()
=> "John Doe"

c.months_since_creation()
=> '1 month'

非常感谢您的任何想法。

推荐答案

逻辑，需要在域对象的实例要调用的最好的地方将是一个此域对象的原型。

The best place for logic that needs to be invoked on an instance of a domain object would be a prototype of this domain object.

您可以写类似的规定：

services.factory('CustomerService', ['$resource', function($resource) {

    var CustomerService = $resource('http://virtualmaster.apiary.io/customers/:id', {}, {
        all: {
            method: 'GET',
            params: {}
        }
        //more custom resources methods go here....
    });

    CustomerService.prototype.fullName = function(){
       return this.first_name + ' ' + this.last_name;
    };

    //more prototype methods go here....

    return CustomerService;    

}]);
