Rails:在模型之间共享枚举声明值 [英] Rails: Share enum declaration values between models

问题描述

我正在对以下属性应用 enum:透明度

I'm applying enum on the following attribute: transparency

相同的属性(带有枚举)用于两种不同的模型:Category 和 Post

The same attribute (with enum) is used in two different models: Category and Post

是否可以在模型之间共享枚举值，以避免代码重复:

Is it possible to share the enum values between models, to avoid code duplication:

enum transparency: %w(anonymous private public)

推荐答案

您可以使用 关注.

module HasTransparency
  extend ActiveSupport::Concern
  included do
    enum transparency: %w(anonymous private public)
  end
end

然后将其包含在您的模型中:

Then include it in your models:

class Category < ActiveRecord::Base
  include HasTransparency

  ....
end
