ruby-on-rails - Ruby on Rails - 使用国家选择器显示国家真实姓名

Question

在我的 Rails 应用程序中，我安装了以下 gem

gem 'countries'
gem 'country_select'
gem 'simple_form'

当用户注册时，他们选择一个国家(例如英国)

在用户的展示页面`

<%= @user.country %>` => Displays GB

我的问题是，如何将英国显示为全名？

Answer 1

来自 the countries gem's github page :

This gem automatically integrates with country_select. It will change its behavior to store the alpha2 country code instead of the country name.

然后，从country_select的github page

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
