Hello, I've updated the worlddb gem that includes models for places, continent, countries, regions, cities and more. The worlddb gem also includes free open public domain plain text fixtures for all countries and territories in the world plus some regions/states/provinces and some cities/towns/hamlets. Use it like
c = City.find_by(key: 'wien'); c.country.name # => 'Austria'and so on. Cheers.
