ArTranslate
Store values for multiple languages in an ActiveRecord attribute using PostgreSQL's hstore.
Installation
Add the gem to your application's Gemfile:
gem 'ar_translate'
Usage
Create a hstore column of the pluralized attribute name:
add_column :posts, :descriptions, :hstore
Add the following to your model:
class Post < ActiveRecord::Base
extend ArTranslate
translates :descriptions, languages: %w(de en es)
end
Now you have access to the following methods:
post = Post.new
post.description_de = 'Hallo wie geht es dir?'
post.description_en = 'Whats up?'
post.descriptions
# => { 'de' => 'Hallo wie geht es dir?', 'en' => 'Whats up?' }
post.description_de
# => 'Hallo wie geht es dir?'
post.description_languages
# => ['de', 'en', 'es']
post.description_attributes
# => [:description_de, :description_en, :description_es]
# The two methods above also work at class level:
Post.description_languages # => [...]
Post.description_attributes # => [...]
This makes it really easy to use forms with translated attributes:
= form_for @post do |f|
= f.text_field :name
- @post.description_attributes.each do |attr|
= f.text_field attr
Or you can add validations to your model:
class Post < ActiveRecord::Base
extend ArTranslate
translates :descriptions, languages: %w(de en es)
description_attributes.each do |attr|
validates attr, length: { in: 20..200 }
end
end
