如何从模型中调用辅助方法? [英] How to call helper method from model?

问题描述

我在MongoID gem的Rails应用程序中将MongoDB用作数据库.我想从带有n aafter_create回调方法的模型中调用辅助方法.怎么可能?
我的模型代码是:

I use MongoDB as database in my Rails application with MongoID gem. I want to call helper method from model with n aafter_create callback method. How is it possible?
My model code is:

class Department
  include ApplicationHelper
  after_create :create_news
  private
  def create_news
    @user = ApplicationHelper.get_current_users
  end
end

我的助手代码是:

And my helper code is:

module ApplicationHelper
  def get_current_users
    current_user
  end
end

当我创建新部门时，会发生以下错误.

When I create new department then following error occur.

undefined method `get_current_users' for ApplicationHelper:Module

如何清除错误?
预先感谢.

推荐答案

我也使用蒙古包，并一直使用它.但是，对于蒙古人来说不应该是唯一的.

I also use mongoid and use this all the time. Shouldn't be unique to mongoid though.

ApplicationController.helpers.my_helper_method
