ruby-on-rails - 设计如何在登录后重定向到不同的页面(基于某些参数)？

Question

在我的应用程序中，我有两个来自两个 Controller 的不同登录表单，它们都将通过 Devise::SessionsController 登录，问题是在成功登录(或失败)后，我需要重定向到特定于 Controller 的不同页面。我怎样才能做到这一点。我目前在我的 Devise::SessionsController 中有这个

class SessionsController < Devise::SessionsController
    def create
        resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#failure")
        return sign_in_and_redirect(resource_name, resource)
      end

      def sign_in_and_redirect(resource_or_scope, resource=nil)
        scope = Devise::Mapping.find_scope!(resource_or_scope)
        resource ||= resource_or_scope
        sign_in(scope, resource) unless warden.user(scope) == resource
        redirect_to dashboard_path
      end

      def failure      
        redirect_to index_path
      end
end

在应用程序 Controller 中

  before_filter :store_location
  def store_location
    unless params[:controller] == "devise/sessions"
      url = #calculate the url here based on a params[:token] which you passed in
      session[:user_return_to] = url
    end
  end

  def stored_location_for(resource_or_scope)
    session[:user_return_to] || super
  end

  def after_sign_in_path_for(resource)
    stored_location_for(resource) || root_path
  end
