Question

我一直在努力让我的考试通过。我认为问题出在我的signin_path上，但我无法确定问题的确切位置，任何帮助都将不胜感激！

这是失败消息（很长时间。抱歉）：

         end
       end
     end  
   end

这是session_helper.rb：

   module SessionsHelper
     require 'sessions_helper'

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

     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

我还没想出如何发布HTML，但如果看到applicait.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！

Answer 1

SessionsHelper模块中的最后一个方法current_user不需要使用参数用户。这就是为什么你看到错误“错误的参数数量（0表示1）。”
