我的工厂有以下内容.rb：
factory :ffsupervisor, class: Supervisor do
first_name "ffsupervisor"
email "ffsupervisor@abc.com"
password "123456"
type "Supervisor"
association :agency, name: "FFAgency", full_fee: "2.0", partial_fee: "1.0", agency_type: "Fulfilment"
end
我可以在Rails控制台中使用FactoryGirl::create(:ffsupervisor)在我的数据库中构建和保存Supervisor实例。当我尝试在我的功能规格中做同样的事情时，我最终得到了：
NoMethodError：未定义的方法`stringify_keys'。
我在SO中就这个问题调查了很多问题。虽然没有弄清楚我错过了什么。对此有所了解会很棒。 TIA！
编辑： 这是我得到的堆栈跟踪：
1) Workflow order_item lifecycle.
Failure/Error: @supervisor= FactoryGirl::create(:ffsupervisor) # Creates both agency & supervisor.
NoMethodError:
