Ruby on Rails- Display Country Real Name with country-selector

Question

In my Rails application, I installed the following gems

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

When a user signs up, they select a country (ex. United Kingdom)

on the User's Show page `

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

My question is, how do I display United Kingdom as full name?

Answer 1

From 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.

Then, from country_select's 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

Answer 2

@user.country will return a country object, ie an instance of class Country. When you put this inside the erb tag, it will have "to_s" called on it as rails tries its best to make a string out of an object. If the class defines a to_s method, then this is what is returned - i'm guessing it does and this method returns the country code.

You need to call the .name method on the country to get the name:

<%= @user.country.name %>

Answer 3

I believe the problem is to do with a missing gem here.

For this to work in your User model:

def country_name
    country = ISO3166::Country[country_code]
    country.translations[I18n.locale.to_s] || country.name
  end
end

You need to have the "countries" gem installed as well as the country_select gem.
