Translation

Overview​

We can convert certain keys to the language the application needs.

Installation​

rails generate 'i18n:active_record:install'

Usage​

  • Create a migration to add a column for locale for the user.
class AddLocaleToUser < ActiveRecord::Migration[7.2]
  def change
    add_column :users, :locale, :string, default: 'en'
  end
end
  • Add the following line to the config/initializers/i18n_active_record.rb file.
require 'i18n/backend/active_record'

I18n.backend = I18n::Backend::Chain.new(
  I18n::Backend::ActiveRecord.new, # DB-backed translations (editable at runtime)
  I18n.backend # fallback to the default Simple backend
)

I18n::Backend::ActiveRecord.configure do |config|
  config.cache_translations = true # defaults to false
  # config.cleanup_with_destroy = true # defaults to false
  config.scope = 'cm_admin' # defaults to nil, won't be used
end

  • We can create a translation by going to /cm_admin/translations.
  - key - The text that needs to be converted. Eg: Edit
  - value - The value that needs to be applied. Eg: ÙŠŰ­Ű±Ű±
  - locale - The language in which the text needs to be converted. Eg: ar
  • Add this method to the CM admin application controller
around_action :switch_locale

def switch_locale(&action)
  locale = params[:locale] || Current.user.locale || I18n.default_locale
  I18n.with_locale(locale, &action)
end

Important Notes​

  • Success messages are not converted yet.
