通过ApplicationRecord Rails扩展模块5

Question

I am trying to extend a module in the application_record.rb file in Rails 5.0. 我试图在Rails 5.0中的application_record.rb文件中扩展一个模块。

The module is located in the /lib folder: 该模块位于/ lib文件夹中：

class ApplicationRecord < ActiveRecord::Base
  self.abstract_class = true
  extend UpdateLive
  extend UpdatePre
end

When trying to use a method in one of the Models I get the following error: 当尝试在其中一个模型中使用方法时，我收到以下错误：

NameError: uninitialized constant ApplicationRecord::UpdateLive

I can't seem to figure out what I am doing wrong, or if I forgot a step? 我似乎无法弄清楚我做错了什么，或者我忘记了一步？

You need to require update_live in your ApplicationRecord 您需要在ApplicationRecord中要求update_live

require 'update_live'

or put lib folder in the autoload path. 或者将lib文件夹放在自动加载路径中。 In application.rb : 在application.rb ：

config.autoload_paths << Rails.root.join('lib')
