ruby-on-rails-3 - FactoryGirl 的未定义方法 after_create

Question

我尝试使用 after_create 回调在 FactoryGirl 中定义 has_many 关系，如/spec/factories/emails.rb 中所示:

FactoryGirl.define do
    factory :email do
        after_create do |email|
            email.attachments << FactoryGirl.build(:attachment)
        end
    end
end

附件在单独的工厂/spec/factories/attachment.rb中定义:

FactoryGirl.define do
    factory :attachment do
        # Attach the file to paperclip
        file { fixture_file_upload(Rails.root.join('spec', 'support', 'myimage.png'), 'image/png') }
    end
end

在我的规范中使用 :attachment 工作得非常好，所以我相信工厂不是问题，但是当我尝试从工厂创建 :email 时，我会抛出以下异常:

Failure/Error: email = FactoryGirl.create(:email)
    NoMethodError:
        undefined method `after_create=' for #<Email:0x007ff0943eb8e0>

我有点不知所措，似乎找不到其他人遇到同样的错误。

工厂女孩 recently changed回调的语法。我认为以下方法会起作用:

FactoryGirl.define do
  factory :email do
    after(:create) do |email|
      email.attachments << FactoryGirl.build(:attachment)
    end
  end
end
