Question

我正在使用ActiveAdmin自定义User模型（不包含Devise）和自定义SessionsController。我成功安装了ActiveAdmin，实施了必要的方法，但面临一个问题：在第一次访问仪表板后，用户remember_token从Cookie中删除（我在浏览器中找到它）导致注销用户并重定向到网站的主页。

在Rails日志中，对用户模型进行了以下更改：

D, [2015-03-06T18:08:38.412548 #29316] DEBUG -- :   User Load (0.2ms)  SELECT  "users".* FROM "users" WHERE "users"."remember_token" = $1  ORDER BY login ASC LIMIT 1  [["remember_token", "d983c4abdc252ffc04a71260513ace78534a4c2b"]]

配置/初始化/ active_admin.rb

ActiveAdmin.setup do |config|
  config.site_title = "Coordinate"
  config.authentication_method = :authenticate_admin_user!
  config.logout_link_path = :sign_out
  config.logout_link_method = :delete
  config.batch_actions = true
end

应用程序/控制器/ application_controller.rb

  def authenticate_admin_user!
    unless current_admin_user
      flash[:error] = "Access error!"
      redirect_to root_path 
    end 
  end 

  def current_admin_user
    return nil if signed_in? && !current_user.admin?
    current_user
  end

应用程序/助手/ sessions_helper.rb

  def sign_in(user)
    remember_token = User.new_remember_token();
    cookies.permanent[:remember_token] = remember_token;
    user.update_attribute(:remember_token, User.encrypt(remember_token));
    self.current_user=user;
  end 

  def current_user
    remember_token= User.encrypt(cookies[:remember_token]);
    @current_user ||= User.find_by(remember_token: remember_token);
  end 


  def current_user?(user)
    user==current_user;
  end 

  def signed_in?
    !current_user.nil?
  end 

  def sign_out()
    current_user.update_attribute(:remember_token, User.encrypt(User.new_remember_token));
    cookies.delete(:remember_token);
    self.current_user=nil;
  end

请帮助解决这个问题。

Answer 1

current_user是零。对？

好像你没有根据你的remember_token来自cookie初始化它。您应该使用authenticate_admin_user!方法初始化它。

Answer 2

我决定在配置文件ActiveAdmin中设置值config.logout_link_path = false

Rails + ActiveAdmin与自定义用户模型（没有设计）：
