未初始化的常量ActiveRecord（NameError）-黄瓜和奶酪示例

Question

我是红宝石的新手，并沿用Cheezy在他的《黄瓜和奶酪》一书中的榜样。

我的gemfile看起来像这样：

source 'https://rubygems.org'

gem 'cucumber'
gem 'rspec'
gem 'page-object'
gem 'pry-debugger'
gem 'faker'
gem 'data_magic'
gem 'debugger', '1.6.6'
gem 'require_all'
gem 'activerecord', '3.2.1'
gem 'factory_girl'
gem 'database_cleaner'
gem 'sqlite3'

---

我有一个名为database.rb的文件（在支持下生活），其中包含：

require 'active_record'
require 'database_cleaner'
require 'factory_girl'
require 'sqlite3'

ActiveRecord::Base.establish_connection(
    :adapter => 'sqlite3',
    :database => '../puppies/db/development.sqlite3')

---

我的env.rb文件包含：

require 'rspec-expectations'
require 'page-object'
require 'page-object/page_factory'
require 'watir-webdriver'
require 'data_magic'
require 'require_all'

require_all File.dirname(__FILE__) + '/pages'

PageObject::PageFactory.routes= {
    :default => [[HomePage, :view_details_for_puppy],
    [DetailsPage, :add_to_cart],
    [ShoppingCartPage, :complete_adoption],
    [CheckoutPage, :checkout]]}

World(PageObject::PageFactory)

---

我的课程页面：

User.rb

class User < ActiveRecord::Base
end

Order.rb

class Order < ActiveRecord::Base
  has_many :adoption
end

User.rb

class User < ActiveRecord::Base
  has_many :adoption
end

Adoption.rb

class Adoption < ActiveRecord::Base
  belongs_to :order
  belongs_to :puppy
end

---

尝试运行第一个CRUD方案时出现此错误：

test_puppies_one djLaX805$ bundle exec cucumber -t @crud1

有什么想法吗？ 我完全按照他的方式去看他的书。

我在几分钟前遇到了这个问题，并通过使用rails gcumber：install命令解决了这个问题。
