Rails Simple_Form: How to show long name of the country

问题

I use simple_form gem to select country:

= simple_form_for @shop, :url => { :action => "create" }, :html => {:id => 'new_shop' } do |f|
  = f.simple_fields_for :address, :html => {:multipart => true} do |o|
    = o.input :country, :label => "Country"

But the name of the country is being saved in short format in the database (like RU, FR, AU, and so on).

I wonder, how can I show the full, long name of the country in the views? Thanks!

回答1:

Actually is a good idea saving the country code in the database (not the long name) because I18n. Having the code you can get later the name as follows:

class User < ActiveRecord::Base
  # Assuming country_select is used with User attribute `country_code`
  # This will attempt to translate the country name and use the default
  # (usually English) name if no translation is available
  def country_name
    country = ISO3166::Country[country_code]
    country.translations[I18n.locale.to_s] || country.name
  end
end
