FactoryGirl.define do
  factory :organization do

    name 'example'

    factory :organization_with_links do

      transient do
        links_count 5
      end

      after(:create) do |organization,evaluator|
        create_list(:link,evaluator.links_count,organization: organization)
      end
    end
  end
end

不幸的是我得到了

NoMethodError: undefined method `links_count' for  FactoryGirl::SyntaxRunner:0x007fcefb1ff780>

根据officall工厂女孩指导我正在做的一切正常：https://github.com/thoughtbot/factory_girl/blob/master/GETTING_STARTED.md#associations

任何建议如何使瞬态变量工作？
