Ruby on rails Rails教程第9章：授权重定向测试失败

我已经浏览了几乎所有Rails教程第9章关于StackOverflow的问题。似乎没有人有同样的问题。也许这只是一个打字错误或是我错过的一些愚蠢的事情，我只是需要一些新鲜的眼睛。任何帮助都将不胜感激

之前的错误基本上是说用户没有在应该登录的时候登录。
不确定5年后这是否有用。但我在一两年前意识到问题在于：我在返回整个用户记录，而我本应该返回一个字段。因此，失败的测试和由此产生的错误。
常见的因素似乎是你的
符号在
方法中；我猜这不起作用，这就是为什么这些操作将转到登录页面而不是根。i、 e.用户在执行您正在测试的操作之前没有实际登录。你能分享吗？好的。添加了sessions\u helper，其中包含
sign\u in
方法。您是否在
specs/spec\u helper.rb
或
specs/support/
中定义了
sign\u in
方法？如果是的话，你能提供代码吗？当然可以。我添加了另一个编辑，包括spec/support/utilities.rb中的内容，感谢这两个更新；我建议您在会话助手的
signed\u-in？
和
current\u-user
方法中以及使用的
sign\u-in
方法中进行一些调试。从错误中，我认为您会发现
signed\u in？
返回false，因为
当前用户
无法从cookie中找到用户，可能是因为
sign\u in
未正确生成和存储cookie。
def signed_in_user
  puts current_user
  unless signed_in?
    store_location
    redirect_to signin_url, notice: "Please sign in."
  end
end
