Module: Glib::CountryList

Defined in:
app/models/glib/country_list.rb

Overview

ISO 3166 country data for country dropdowns.

Backed entirely by the countries gem, so there is no table to migrate or seed, and renames (Türkiye, Czechia) arrive with a bundle update. Store the alpha-2 code rather than the name, so a rename never invalidates existing data.

  country = ISO3166::Country[code]
  country && (country.common_name || country.iso_short_name)
end

.options ⇒ Object

common_name is what people actually call the place ("South Korea", "United Kingdom") rather than the formal ISO name ("Korea (Republic of)").
