RailsAdmin配置中的重定向失败

标签： ruby-on-rails devise

如果用户不是管理员，我将RailsAdmin设置为重定向到主页。但是，重定向失败。这是我收到的错误消息：

ActionController::UrlGenerationError in RailsAdmin::MainController#dashboard
No route matches {:controller=>"home", :action=>"index"} missing required keys: []

rails_admin.rb中的代码如下。在配置文件的顶部：

ADMIN_EMAILS= ['my@email.com']

此处的其他代码仅限制访问管理员：

  config.authorize_with do 
    is_admin = ADMIN_EMAILS.include?(current_user.email) 
    if current_user
      redirect_to root_path unless is_admin 
    end
  end

这是完整的堆栈跟踪：

我希望你已经明白了这一点。我自己正在完成这个工作，发现我必须使用它才能使它工作：

redirect_to main_app.root_path

否则你会遇到RailsAdmin引擎中的路由。
