为什么我得到的FactoryGirl错误的参数数量错误?

在无轨应用程序中，FactoryGirl有奇怪的行为.错误的参数数量错误...不知道为什么.

Having strange behavior from FactoryGirl in non-rails app. getting wrong number of arguments error...don't know why.

gideon@thefonso ~/Sites/testing (master)$ rspec spec
/Users/gideon/.rvm/gems/ruby-1.9.3-p194/gems/factory_girl-4.1.0/lib/factory_girl/syntax/default.rb:6:in `define': wrong number of arguments (1 for 0) (ArgumentError)
    from /Users/gideon/Sites/testing/spec/factories.rb:1:in `<top (required)>'

这是其中涉及的文件...

Here are the files involved...
