我需要访问当前控制器或从观察者方法中刷新通知.

class SomeObserver < ActiveRecord::Observer
    observe :some_model
    cattr_accessor :current_controller

    def after_create(record)
        ...
        current_controller.flash[:notice] = "Some message!"
    end
end

class ApplicationController < ActionController::Base
    before_filter do
        SomeObserver.current_controller = self
    end
    ...
end
