Module: LocalizedCountrySelect

Defined in:
lib/localized_country_select.rb

Overview

LocalizedCountrySelect

View helper for displaying select list with countries:

country_select(:user, :country)

Works just like the default Rails’ country_select plugin, but stores countries as country codes, not names, in the database.

You can easily translate country codes in your application like this:

<%= I18n.t @user.country, :scope => 'countries' %>

Uses the Rails internationalization framework (I18n) for translating the names of countries.

Use Rake task rake import:country_select 'de' for importing country names from Unicode.org’s CLDR repository (www.unicode.org/cldr/data/charts/summary/root.html)

Code adapted from Rails’ default country_select plugin (previously in core) See github.com/rails/country_select/tree/master/lib/country_select.rb
