Currency to words¶ ↑

Provides a view helper for Rails that translate a currency amount to words (eg. to_words(200) => ‘dvě stě korun’).

This helper comes with two supported locales (Czech and Polish) but it is possible and easy to implement your own (see “Implementing a new locale”).

Add the gem to your Gemfile.

gem 'currency_to_words'

Install gem and create locale file in your project where you want to provide translation from currency to words. You can use locale file from I18n files below section or create your own.

In your views write for example:

currency_to_words(235.58)

Warning: Be sure that you are using correct syntax of arrays. I have had problem with “Argument error” after production server restart. Reason was that I did not have spaces in the arrays. So the correct syntax is …‘čtyřicet’, ‘padesát’… and so on.

If you need locale that is not supported yet, you can easily add one. All you need to do is translate locale file and create class in /lib. Convention is that the class has to be named [locale]Currency.

So for example EnCurrency or FrCurrency. So override or duplicate the existing class and add diffrences of your language. Thats it!

This project is heavily inspirated by bcarrere/currency-in-words and uses blocks of code from this repository.

Reason for creating my own repository was requirement to use I18n gem for “currency to words” translation and also for settings. This means, that this gem can be configured from locale file and translation is not hardcoded to source of library.

Did you created locales that is not supported here yet? Please write me e-mail if you want contribute at majak108@gmail.com.
