我正在编写ruby on rails教程，但是在使用FactoryGirl进行测试时遇到了一些问题。下面是我的错误信息:

这是我的工厂。rb:
FactoryGirl.define do
factory :user do
user.name "abc"
user.email "abc@example.com"
user.password "foobar"
user.password_confirmation "foobar"
end
end
下面是我在user_controller_spec.rb中使用的代码:
before(:each) do
@user = FactoryGirl.create(:user)
end
我已经尝试了前面问的问题中的方法，但他们没有工作。有人能帮我一下吗?谢谢!
您的工厂文件应该是:
FactoryGirl.define do
factory :user do
name "abc"
email "abc@example.com"
password "foobar"
password_confirmation "foobar"
end
end
,将工作。
你在初始版本中使用了一个局部变量'user'。问题是没有本地变量user传递给，或者在块中定义。正如上面的一位评论者指出的那样——如果你想调用user.name，那么你必须将|user|传递给block。例如
FactoryGirl.define do
factory :user do |user|
etc.
但是在FactoryGirl中这是不必要的。你可以像我上面输入的那样做。
我建议阅读https://github.com/thoughtbot/factory_girl/wiki/Usage -即使你只是通过教程学习Rails(就像我一样)，它也非常容易访问:-)
