Ruby on rails 创建使用当前种子记录的FactoryGirl定义

我遇到了与FactoryGirl的GitHub页面（）相同的问题，唯一性验证被种子数据绊倒

我的工厂原来是这样的：

factory :country, class: MyApp::Models::Country do
  code { MyApp::Models::Country.first.code }
  name { MyApp::Models::Country.first.name }
end

不理想，弄坏了门楣，因此我使用#623中的建议进行了重构：

但是，我现在得到了以下关于linting的错误堆栈：

/Users/philostler/.rvm/gems/ruby-2.1.2/gems/activemodel-4.1.4/lib/active_model/attribute_methods.rb:435:in `method_missing': undefined method `intitalize_with=' for #<MyApp::Models::Country id: nil, code: nil, name: nil> (NoMethodError)

它现在正试图在一个空白的模型对象上调用initalize_with=，当然这个对象会掉下来

我只是希望工厂使用一个已经存在的记录，同时仍然通过皮棉

---

我这样做是错误的还是有错误（可能是因为我使用的是名称空间）？

在使用FactoryGirl并使用常量声明

类时，我经常遇到不相关的奇怪错误。使用字符串修复了我这边的情况，这当然与自动加载相关

我不知道这是否是你的解决方案，但你可以尝试（对你所有的工厂都这样做）

恐怕没有效果，但这在将来很容易知道。谢谢
