Installation

Add this line to your application's Gemfile:

gem 'progne_tapera'

And then execute:

$ bundle

Or install it yourself as:

$ gem install progne_tapera

Usage

config/initializers/enum.rb

Unidom::Common::YamlHelper.load_enum config: Rails.configuration, root: Rails.root

config/enum.yml

enum:

  gender:
    male:
      code: '1'
    female:
      code: '2'
    not_specified:
      code: '9'

  china_ethnicity:
    han:
      code: HA
      numeric_code: '01'
    mongel:
      code: 'MG'
      numeric_code: '02'

config/locales/enum.zh-CN.yml

'zh-CN':
  enum:

    gender:
      male:          男
      female:        女
      not_specified: 未指定

    china_ethnicity:
      han:    汉
      mongel: 蒙古

app/types/gender.rb

class Gender < ActiveRecord::Type::Value

  include ProgneTapera::EnumConfig

  enum

end

app/types/ethnicity.rb

class Ethnicity < ActiveRecord::Type::Value

  # The Item Methods module must be defined before the ``enum :china_ethnicity`` code block, so it could be called there.
  module ItemMethods

    extend ActiveSupport::Concern

    included do |includer|

      def major?
        'HA'==code
      end
      # Ethnicity::HAN.major? returns true
      # Ethnicity::MONGEL.major? returns false

    end

  end

  include ProgneTapera::EnumConfig

  enum :china_ethnicity
  # 用 :china_ethnicity 指定的 i18n 资源。

end

app/types/ethnicity.rb

class Ethnicity < ActiveRecord::Type::Value

  include ProgneTapera::EnumConfig

  enum :china_ethnicity_alphabetic, :china_ethnicity
  # 以民族字母代码为代码，用 :china_ethnicity 指定的 i18n 资源。

end

app/types/ethnicity.rb

class Ethnicity < ActiveRecord::Type::Value

  include ProgneTapera::EnumConfig

  enum :china_ethnicity_numeric, :china_ethnicity
  # 民族数字代码，用 :china_ethnicity 指定的 i18n 资源。

end

在某处需要调用民族 (Ethnicity) 枚举型的代码中：

Ethnicity::HAN.code           # 'HA'
Ethnicity::HAN.localized_name # '汉'

在使用枚举型的模型中：（如 app/models/person.rb）

class Person < ActiveRecord::Base
  code :ethnicity, Ethnicity
  # The :ethnicity above implies the Person model has the :ethnicity_code field.
end

Include the Concerns

include ProgneTapera::EnumList
include ProgneTapera::EnumConfig
include ProgneTapera::EnumCode

Enum List concern

The Enum List concern do the following tasks for the includer automatically:

  1. Include the Enumerable module

  2. Define the .enum_name method as: enum_name(name = nil)

  3. Define the .item_defined? method as: item_defined?(item)

  4. Define the .add_item method as: add_item(item)

  5. Define the .safe_add_item method as: safe_add_item(item)

  6. Define the .enum_constants method as: enum_constants

  7. Define the .all method as: all

  8. Define the .selected method as: selected(&block)

  9. Define the .each method as: each(&block)

  10. Define the .lookup method as: lookup(code)

  11. Define the .form_options method as: form_options(&block)

  12. Define the .deserialize method as: deserialize(value)

  13. Define the .serialize method as: serialize(value)

gender = Gender.lookup '1' # Lookup the gender per code
gender.name                # male

Gender.form_options        # { '男' => '1', '女' => '2', '未指定' => '9' }
# It's useful for the HTML select options

Enum Config concern

The Enum Config concern do the following tasks for the includer automatically:

  1. Include the Enum List concern

  2. Define the .enum method as: enum(name = nil, localized_name = name, &block)

  3. Define the .overload_enum_i18n method as: overload_enum_i18n(localized_name = nil)

config/locales/enum.zh-CN.yml

'zh-CN':
  enum:

    china_ethnicity_overloaded:
      han:    汉族
      mongel: 蒙古族
# Overload the i18n resources of the Ethnicity enum code
Ethnicity.class_eval do
  overload_enum_i18n :china_ethnicity_overloaded
end

在某处需要调用民族 (Ethnicity) 枚举型的代码中：

Ethnicity::HAN.code           # 'HA'
Ethnicity::HAN.localized_name # '汉族' not '汉'

基于数据或者其他的方式扩展枚举型：

Ethnicity.enum do
  {
    miao: { code: 'MH', numeric_code: '06', localized_name: '苗' },
    yi:   { code: 'YI', numeric_code: '07', localized_name: '彝' }
  }
end

Ethnicity::MIAO.code           # 'MH'
Ethnicity::MIAO.localized_name # '苗'
Ethnicity::YI.code             # 'YI'
Ethnicity::YI.localized_name   # '彝'

Enum Code concern

The Enum Code concern do the following tasks for the includer automatically:

  1. Define the .code method as: code(field, enum)
