Rails Simple_Form：如何显示国家的长名称 [英] Rails Simple_Form: How to show long name of the country

问题描述

  = 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 => 国家
  

但是国家的名字正在以短格式保存在数据库中code> RU ， FR ， AU 等等）。

我想知道，如何在视图中显示国家的完整名称？谢谢！
解决方案实际上是一个好主意，因为I18n在数据库中保存国家代码（不是长名称）。有了代码，你可以在后面得到如下的名字：

  class User< ActiveRecord :: Base 
＃假设country_select和User属性`country_code`一起使用
＃这将尝试翻译国名，如果没有翻译，使用默认的
＃（通常是英文）可用
 def country_name 
国家= ISO3166 ::国家[country_code] 
 country.translations [I18n.locale.to_s] || country.name 
 end 
 end 
  

检查： country_select：从国家/地区获取国名

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!

解决方案

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
