Question

我正在研究ruby on rails教程，但在使用FactoryGirl进行测试时遇到了问题。这是我的错误信息：

这是我的个工厂.rb：

FactoryGirl.define do
  factory :user do
    user.name "abc"
    user.email "abc@example.com"
    user.password "foobar"
    user.password_confirmation "foobar"
  end
end

这是我在user_controller_spec.rb中使用的代码：

before(:each) do
  @user = FactoryGirl.create(:user)
end

我在以前的问题中尝试了这些方法，但它们没有用。任何人都可以帮我吗？谢谢！

Answer 1

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

那会有用。

您在初始版本中使用了本地变量'user'。问题是没有局部变量用户传递给或在块中定义。正如上面的一位评论者指出的那样 - 如果你想调用user.name，那么你必须传递| user |到街区。即。

FactoryGirl.define do
  factory :user do |user|
  etc.

但在FactoryGirl中没有必要这样做。你可以在上面输入它时这样做。

我建议阅读https://github.com/thoughtbot/factory_girl/wiki/Usage - 即使您只是通过教程学习Rails（就像我一样），它也非常易于访问： - ）
