我一直无法通过考试。我认为问题出在我的 signin_path 上，但我无法弄清楚问题到底出在哪里，任何帮助将不胜感激！

这是失败消息（很长。对此感到抱歉）：

bundle exec rspec spec/......................FFFFFFFFFFFFFFFFFF

这是 session_helper.rb：

   module SessionsHelper

     def sign_in(user)
       cookies.permanent[:remember_token] = user.remember_token
       self.current_user = user

     def signed_in?
        !current_user.nil?
     end

     def current_user=(user)
       @current_user = user
     end

     def current_user(user)
       @current_user ||= User.find_by_remember_token(cookies[:remember_token])
      end
end

我还没有弄清楚如何让 HTML 发布，但如果查看 applicaiton.html.erb 和 _header.html.erb 会有所帮助，请告诉我，我会继续尝试。任何想法将不胜感激！谢谢！

SessionsHelper 模块中的最后一个方法 current_user 不需要使用参数 user。这就是您看到错误“参数数量错误（0 代表 1）”的原因。
