IsoCountriesPlus

This gem differs from other ISO country gems in that it allows VERY flexible name lookups by cross-compiling additional country name standards, so country names like 'South Korea' and 'Russia' will work properly. It uses a file compiled by OpenGeocode.org consisting of the ISO 3166-1 country names (including foreign variants) and codes, as well as the U.S. Board on Geographic Names (BGN), United Nations Group of Experts on Geographic Names (UNGEGN), and U.K. Permanent Committee on Geographic Names (PCGN) country names.

Installation

Add this line to your application's Gemfile:

gem 'iso_countries_plus'

And then execute:

$ bundle

Or install it yourself as:

$ gem install iso_countries_plus

IsoCountry.all

IsoCountry.find_by_name("Russia")

Features

Combined countries like 'Bosnia and Herzegovina' will also be accessible individually as 'Bosnia' and 'Herzegovina'.

Grouped islands like Pitcairn, Henderson, Ducie, and Oeno Islands will also be accessible as (for example) "Pitcairn", "Ducie Island", and "Oeno Islands" (i.e the name with and without the "Island" and "Islands" suffixes).

Country names are also stored in lowercase. This is useful for allowing more flexibility for user input or when values are entered as all caps.

For example:

country = "GERMANY"
IsoCountry.find_by_name(country.downcase)
