Ruby on rails 设计：注册控制器不'；不显示即时消息

我已经创建了注册控制器，该控制器覆盖Desive上的默认值。除了flash消息外，一切都很正常-当用户进行新注册时，我想在我的主页上重定向他，并向他显示一条有关正在发生的事情的flash消息，如下图所示：

class RegistrationsController < Devise::RegistrationsController
  def new
    super
  end

  def create
    resource = build_resource(params[:user])
    # add custom create logic here
    if params[:referrer_key].nil?
      puts 'A'
      puts resource.inspect
      if resource.save
        puts 'B'
        if resource.active_for_authentication?
          #flash[:notice] = "Welcome!" # doesn't work neither
          Notification.welcome(@user).deliver unless @user.invalid? # overriding original methods       
          sign_in(@user)
          redirect_to root_url, :notice => "Welcome!"
        else
          set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
          expire_session_data_after_sign_in!
          respond_with resource, :location => after_inactive_sign_up_path_for(resource)
        end
      else
        clean_up_passwords resource
        render 'application/splash'
      end

flash消息通常是有效的，但不适用于这种情况

我错过了什么

谢谢您

您必须使用不同的引号，否则div类会出错：

%div{:class => "alert alert-#{type == :notice ? 'success' : type} fadeout", "data-dismiss" => "alert"}

%div{:class => "alert alert-#{type == :notice ? 'success' : type} fadeout", "data-dismiss" => "alert"}
