ruby-on-rails - 工厂女孩中非事件记录协会的问题

Question

我刚开始在测试的时候用factory girl来替换fixtures。我正在开发一个 Twitter 客户端，我正在尝试使用工厂女孩来创建用于测试的 Twitter 对象。当我单独创建它们时就可以了。但是，如果我尝试将它们关联起来，则会出现以下错误。

Factory.define :status, :class => Twitter::Status, :default_strategy => :build do |t|
  t.text 'Test Twitter Status message'
  t.association :user, :factory => :twitter_user #this line causes the problems
end

Factory.define :twitter_user, :class => Twitter::User, :default_strategy => :stub do |u|
  u.profile_image_url "#{RAILS_ROOT}/public/images/rails.png"
end

t.association :user, :factory => :twitter_user 导致问题，因为当它存在时会抛出此异常。有没有什么办法解决这一问题？还是 factory girl 只是为 activerecord 对象设计的？谢谢

Answer 1

我很确定 factory girl 只适用于 ActiveRecord 对象，你应该能够模拟和 stub Twitter::User 对象而不是使用工厂，如果你使用 rSpec 也许(如果我的语法是右):

@twitter_user = mock(Twitter::User, :profile_image =>"#{RAILS_ROOT}/public/images/rails.png")

然后将其附加到需要它的对象上。

这可能不太正确，但这是我要开始的道路。
