How to Translate JavaScript Strings in Rails


Rails I18n and elegant message passing to JavaScript

The process of “internationalization” usually means to abstract all strings and other locale specific bits (such as date or currency formats) out of your application. The process of “localization” means to provide translations and localized formats for these bits.

How I18n in Ruby on Rails Works

The limits of my language are the limits of my world. ‒Ludwig Wittgenstein. With over 6,909 distinct languages in the world and most of them differing in so many different ways (e.g. in pluralization rules), it is difficult to provide specific tools for internalization. However, for unrestricted barriers of languages, Rails I18n API focuses on:

  • providing support for English and similar languages out of the box
  • making it easy to customize and extend everything for other languages

As part of this solution, every static string in the Rails framework – e.g. Active Record validation messages, time and date formats – has been internationalized, so localization of a Rails application means “over-riding” these defaults.
