ruby-on-rails – FactoryGirl RSpec创建工厂对象时,没有方法错误,工厂设置该对象的属

无论何时我创建一个Factory对象,我都会在工厂为该对象设置属性时出现此错误 – 在本例中为’name’.为什么？？？

businesses.rb

FactoryGirl.define do
  factory :business do

    factory :business_main do
      name "Dave's Toys"
    end
  end
end

企业表

 zip                  | character varying(255)      |

business_spec.rb

...
business  = Factory(:business_main)
...

 # Failure/Error: business  = Factory(:business_main)
