This repository contains the I18n ActiveRecord backend and support code that has been extracted from the I18n.
It is fully compatible with Rails 3, 4, 5 and 6.
For Bundler put the following in your Gemfile:
gem 'i18n-active_record', :require => 'i18n/active_record'
After updating your bundle, run the installer
rails g i18n:active_record:install
It creates a migration:
class CreateTranslations < ActiveRecord::Migration def self.up create_table :translations do |t| t.string :locale t.string :key t.text :value t.text :interpolations t.boolean :is_proc, :default => false t.timestamps end end def self.down drop_table :translations end end
To specify table name use:
rails g i18n:active_record:install MyTranslation
With the translation model you will be able to manage your translation, and add new translations or languages through
it.
By default the installer creates a new file in config/initializers named i18n_active_record.rb with the following content.
require 'i18n/backend/active_record' Translation = I18n::Backend::ActiveRecord::Translation if Translation.table_exists? I18n.backend = I18n::Backend::ActiveRecord.new I18n::Backend::ActiveRecord.send(:include, I18n::Backend::Memoize) I18n::Backend::Simple.send(:include, I18n::Backend::Memoize) I18n::Backend::Simple.send(:include, I18n::Backend::Pluralization) I18n.backend = I18n::Backend::Chain.new(I18n::Backend::Simple.new, I18n.backend) end
To perform a simpler installation use:
rails g i18n:active_record:install --simple
It generates:
require 'i18n/backend/active_record' I18n.backend = I18n::Backend::ActiveRecord.new
You may also configure whether the ActiveRecord backend should use destroy
or delete
when cleaning up internally.
I18n::Backend::ActiveRecord.configure do |config| config.cleanup_with_destroy = true # defaults to false end
You can now use I18n.t('Your String')
to lookup translations in the database.
The interpolations field in the Translations table is used by I18n::Backend::ActiveRecord::Missing to store the interpolations seen the first time this Translation was requested. This will help translators understand what interpolations to expect, and thus to include when providing the translations.
The interpolations field is otherwise unused since the “value” in Translation.value is actually used for interpolation during actual translations.
