Ruby on Rails全局ActiveRecord ::枚举 [英] Ruby on Rails Global ActiveRecord::Enum

问题描述

我真的很喜欢Rails 4新的枚举功能，但是我想使用我的枚举

枚举状态：[：active，：inactive， ：删除]

在每个模型。我找不到任何方式如何在 config / initializes / enums.rb 中声明，并包括每个模型

我非常新的 Ruby on Rails ，需要您的帮助才能找到解决方案

解决方案

使用 ActiveSupport :: Concern 为 dry 创建的此功能创建型号代码：

 ＃app / models / concern / my_enums.rb 
 module MyEnums 
 extends ActiveSupport :: Concern 
 
包含
枚举状态：[：active，不活动，已删除] 
 end 
 end 
 
＃app / models / my_model.rb 
 class MyModel< ActiveRecord :: Base 
包括MyEnums 
 end 
 
＃app / models / other_model.rb 
 class OtherModel 
 include MyEnums 
 end

I really like Rails 4 new Enum feature, but I want to use my enum

enum status: [:active, :inactive, :deleted]

in every model. I cannot find any way how to declare for example in config/initializes/enums.rb and include every model

I'm very new in Ruby on Rails and need your help to find solution

解决方案

Use ActiveSupport::Concern this feature created for drying up model codes:

#app/models/concerns/my_enums.rb
module MyEnums
  extend ActiveSupport::Concern

  included do
    enum status: [:active, :inactive, :deleted]
  end
end

# app/models/my_model.rb
class MyModel < ActiveRecord::Base
  include MyEnums
end

# app/models/other_model.rb
class OtherModel
  include MyEnums
end
