Enumlingo

Enumlingo is a simple gem that helps you translate enum values in your Rails app.

Usage

extend Enumlingo in your model and call enumlingo with the enums you want to translate.

class Product < ApplicationRecord
  extend Enumlingo

  enum status: %i[active inactive]
  enum kind: %i[book food medical other]


  enumlingo :status, :kind
end

define the translations in your locale file

en:
  activerecord:
    attributes:
      product:
        statuses:
          active: "Active"
          inactive: "Inactive"
        kinds:
          book: "Book"
          food: "Food"
          medical: "Medical"
          other: "Other"

"zh-CN":
  activerecord:
    attributes:
      product:
      statuses:
        active: "激活"
        inactive: "未激活"
      kinds:
        book: "书籍"
        food: "食品"
        medical: "医疗"
        other: "其他"

Value translation

product = Product.new(status: :active, kind: :book)
product.status_lingo # => "Active"
product.kind_lingo # => "Book"

I18n.locale = "zh-CN"
product.status_lingo # => "激活"
product.kind_lingo # => "书籍"

Options translation

# Translate options with key
Product.statuses_lingo # => [["Active", "active"], ["Inactive", "inactive"]]
Product.kinds_lingo # => [["Book", "book"], ["Food", "food"], ["Medical", "medical"], ["Other", "other"]]

# Translate options with value
Product.statuses_lingo_values # => [["Active", 0], ["Inactive", 1]]
Product.kinds_lingo_values # => [["Book", 0], ["Food", 1], ["Medical", 2], ["Other", 3]]

Product.status_lingo(:active) # => "Active"

Form translation

<%= form_for @product do |f| %>
  <%= f.select :status, Product.statuses_lingo %>
  <%= f.select :kind, Product.kinds_lingo %>

  ...
<% end %>
