Extend ActiveRecord::Enum for add more helpful methods, from rails/rails#36503.

🚨 This Gem does not change the way you use ActiveRecord::Enum, just adds method extensions.

中文介绍与使用说明

class Book
  enum status: %i[draft published archived]
end

Now we have status_name, status_color, status_value and Book.status_options methods:

• #{attribute}_name - return I18n name for display.
• #{attribute}_color - return color for enum value from I18n file.
• #{attribute}_value - return raw value for enum, Now we don't need use Book.statuses[@book.status].
• Book.#{attribute}_options - return a array list for select tag options, <%= f.select :status, Book.status_options %>.

Write I18n:

en:
  activerecord:
    enums:
      book:
        status:
          draft: Drafting
          published: Published
          archived: Archived
        status_color:
          draft: '#999999'
          published: 'green'
          archived: 'red'

zh-CN:
  activerecord:
    enums:
      book:
        status:
          draft: '草稿'
          published: '已发布'
          archived: '归档'

use the methods:

irb> @book = Book.new(status: :draft)
irb> @book.status_value
0
irb> @book.status_name
"草稿"
irb> @book.status_color
"#999999"
# You can still use the original methods from ActiveRecord::Enum
irb> @book.status
"draft"
irb> @book.draft?
true
irb> @book.published!
irb> @book.published?
true
irb> @book.status
"published"

For _options methods for select helper:

<% form_for(@book) do |f| %>
  <%= f.text_field :name %>
  <%= f.select :status, Book.status_options %>
  <%= f.submit %>
<% end >

Add this line to your application's Gemfile:

gem 'enumize'

And then execute:

$ bundle

You can write color config in en.yml once for all locales, so follow the I18n fallback, the others locale will use color value from en:

config/application.rb

module Dummy
  class Application < Rails::Application
    # Add to tell I18n fallback translate to en
    config.i18n.available_locales = ["en", "zh-CN"]
    config.i18n.fallbacks = true
  end
end
