Cookie无效Rails 5.1.1

标签: ruby-on-rails cookies ruby-on-rails-5.1

打开它时,我在浏览器中显示此消息。我使用的是Rails 5.1.1,ruby 2.4.1,puma 3.9.1。

"未定义的方法`签名'为零:NilClass"指的是cookies.signed

我在Rails 5.0.3中有相同的项目并且它正在工作。我对这条线路进行了评论,但它在每一行都崩溃了#34; cookies"。我试图启动一个新的Rails项目,但问题仍然存在。这是Rails 5.1.1的问题吗?

我的sessions_helper.rb文件包含以下代码:

# frozen_string_literal: true

# Helper for Sessions
module SessionsHelper
  # Logs in the given user.
  def log_in(user)
    session[:user_id] = user.id
  end

  # Remembers a user in a persistent session.
  def remember(user)
    user.remember
    cookies.permanent.signed[:user_id] = user.id
    cookies.permanent[:remember_token] = user.remember_token
  end

  # Returns the user corresponding to the remember token cookie.
  def current_user
    if (user_id = session[:user_id])
      @current_user ||= User.find_by(id: user_id)
    elsif (user_id = cookies.signed[:user_id]) # Error in this line
      user = User.find_by(id: user_id)
      if user && user.authenticated?(cookies[:remember_token])
        log_in user
        @current_user = user
      end
    end
  end

  # Returns true if the user is logged in, false otherwise.
  def logged_in?
    !current_user.nil?
  end

  # Forgets a persistent session.
  def forget(user)
    user.forget
    cookies.delete(:user_id)
    cookies.delete(:remember_token)
  end

  # Logs out the current user.
  def log_out
    forget(current_user)
    session.delete(:user_id)
    @current_user = nil
  end
end
