我正在研究 Ruby on Rails 教程，但在使用 FactoryGirl 进行测试时遇到问题。 这是我的错误信息:

这是我的工厂.rb:
FactoryGirl.define do
factory :user do
user.name "abc"
user.email "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d2b3b0b192b7aab3bfa2beb7fcb1bdbf" rel="noreferrer noopener nofollow">[email protected]</a>"
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
我已经尝试过之前提出的问题中的方法，但没有成功。有人可以帮助我吗？谢谢!
最佳答案
你的工厂文件应该是:
FactoryGirl.define do
factory :user do
name "abc"
email "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="90f1f2f3d0f5e8f1fde0fcf5bef3fffd" rel="noreferrer noopener nofollow">[email protected]</a>"
password "foobar"
password_confirmation "foobar"
end
end
这样就可以了。
您在初始版本中使用了局部变量“user”。问题是没有局部变量用户传递到 block 中或在 block 中定义。正如上面的评论者之一指出的那样 - 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.
但这在 FactoryGirl 中是不必要的。您可以按照我上面输入的方式进行操作。
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)，它也非常容易上手:-)
关于ruby-on-rails - Rails 3，FactoryGirl : wrong number of arguments (1 for 0) (ArgumentError)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15580212/
