Ruby on rails 在Rails中调用资源。AngularJS+；Rails教程

我正在尝试使用ng资源来显示书名索引。这是AngulaRails的第11章，到目前为止，这是非常艰难的

我知道我的问题与尝试使用coffeescript控制器中的资源有关，因为当我使用特定url向我们发送$http“get”请求时，一切正常。以下是我的代码的所有部分：

1.javscripts/application.js

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/sstephenson/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
//= require bootstrap.min
//= require angular.min
//= require angular-resource

//= require angular-application

//= require_self
//= require_tree ./angular

AngulaRails = angular.module("AngulaRails", ["ngResource"]);

2序列化程序：

class BookSerializer < ActiveModel::Serializer
  attributes :id, :title, :author

end

4 javascripts/angular-application.js

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/sstephenson/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
//= require bootstrap.min
//= require angular.min
//= require angular-resource

//= require angular-application

//= require_self
//= require_tree ./angular

AngulaRails = angular.module("AngulaRails", ["ngResource"]);

5我试图查看的索引的索引控制器：

  # GET /books
  def index
    @books = Book.all

    respond_to do |format|
      format.html {   }
      format.json { render json: @books, root: false, each_serializer: BookSerializer }
    end
  end

6我试图使用的资源的工厂。在本例中，我调用索引的查询：

AngulaRails.factory "Book", ($resource) ->
  $resource("/books/:id")
  {
  'get':    {method: 'GET'},
  'save':   {method: 'POST'},
  'query':  {method: 'GET', isArray: true},
  'remove': {method: 'DELETE'},
  'delete': {method: 'DELETE'}
  }

7最后但并非最不重要的是，此应用程序的coffescript控制器：

AngulaRails.controller "BooksController", ($scope,  Book) ->
  $scope.getBooks = () ->
    $scope.books = Book.query()

当我尝试运行此操作时，console.log会给我一个错误提示：

---

错误：Book.query不是函数

工厂声明有问题。它将返回此对象：

  {
  'get':    {method: 'GET'},
  'save':   {method: 'POST'},
  'query':  {method: 'GET', isArray: true},
  'remove': {method: 'DELETE'},
  'delete': {method: 'DELETE'}
  }

。。。其

query

属性是对象，而不是函数。。。因此出现了错误。这可能就是你的意思

($resource) ->
  $resource("/books/:id", {}, 
  {
  'get':    {method: 'GET'},
  'save':   {method: 'POST'},
  'query':  {method: 'GET', isArray: true},
  'remove': {method: 'DELETE'},
  'delete': {method: 'DELETE'}
  })

你的工厂申报单确实有问题。您不需要将操作分配包括到“GET”、“POST”等请求类型，因为这是默认设置

唯一可能出现的问题是默认情况下显示给

POST

请求的更新操作。但是，对于更新数据记录而言，

PUT

请求可能更合理。因此，我包括了

{update:{method:“PUT”}

，它覆盖了默认值

信贷：安格拉雷的书。 这项工作：

  AngulaRails.factory "Book", ($resource) ->
    $resource("/books/:id", {id: "@id"}, {update: {method: "PUT"}})

但是，如果要显式地包含它，请注意正确设置括号

AngulaRails.factory "Book", ($resource) ->
  $resource("/books/:id", {id: "@id"},
  {
   get:    {method: 'GET'},
   save:   {method: 'POST'},
   query:  {method: 'GET', isArray: true},
   remove: {method: 'DELETE'},
   delete: {method: 'DELETE'}
   update: {method: "PUT"}
  })

主要的问题是，我有另一家工厂在建，在我的资产管道中紧跟着这家工厂，所以rails使用了它并超越了这家工厂。摇摇头

但是是的，这个散列不是必需的：

{
  'get':    {method: 'GET'},
  'save':   {method: 'POST'},
  'query':  {method: 'GET', isArray: true},
  'remove': {method: 'DELETE'},
  'delete': {method: 'DELETE'}
  }

尝试过了，但仍然得到相同的“Book.query不是函数”错误谢谢你的回答！！主要的问题是，我有另一家工厂在建，在我的资产管道中紧跟着这家工厂，所以rails使用了它并超越了这家工厂****摇摇头****
