MIT-LICENSE Extract the former country_select helper into a plugin. Sep 18, 2008


Provides a simple helper to get an HTML select list of countries. The list of countries comes from the ISO 3166 standard. While it is a relatively neutral source of country names, it may still offend some users.

Users are strongly advised to evaluate the suitability of this list given their user base.

Latest Changes


  • Fixed incompatibility with Rails 3.2.2 (thanks to jmazzi)


  • Updated the country list to change the name of Libyan Arab Jamahiriya to Libya according to the latest ISO 3166 newsletter
  • A country in the priority list will be selected there and not in the main list (thanks to yyyc514)
  • Removed relics from the pre-gem days


Install as a gem using

gem install country-select

Or put the following in your Gemfile

gem 'country-select'


Simple use supplying model and attribute as parameters:

country_select("user", "country_name")

Supplying priority countries to be placed at the top of the list:

country_select("user", "country_name", [ "United Kingdom", "France", "Germany" ])

Supplying additiontal options:

country_select("user", "country_name", [ "United Kingdom", "France", "Germany" ], {:prompt => "Choose Country"}, {:class => "country-chooser"})

Using together with form_for or fields_for:

<%= form_for @user do |f| %>
  <%= f.country_select("country_name") %>
<% end %>
