I18n::Backend::ActiveRecord
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.
Installation
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.
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
Usage
You can now use I18n.t('Your String')
to lookup translations in the database.
Missing Translations → Interpolations
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.
