### 如何更新数据文件

复制所需文件到你的项目中:

    rails g china_regions:regions

### 如何引入china_regions到你的项目

添加以下代码到你的 Gemfile:

    gem 'china_regions'

安装:

    bundle install

#### 开始构建城市数据

复制所需文件到你的项目中:

    rails g china_regions:install

   随后你可以看到控制台发生的变化:
   * 复制 `db/migrate/xxxxxxxxxxx_create_china_regions_tables.rb` 文件到 `db/migrate` 目录中
   * 复制 `regions.en.yml` 和 `regions.zh.yml` 配置文件到 `config/locales` 目录中

创建所需的表 (provinces, cities, districts):

    rake db:migrate

将所需的模型(Models) [`Province`, `City`, `District`] 到您的应用程式中:

  你可以执行 `rails g` 查看到 `generator` 列表.

    rails g china_regions:regions

查看 app/models:

  - create  app/models/province.rb
  - create  app/models/city.rb
  - create  app/models/district.rb

下载并导入最新数据到你的项目中:

    rake china_regions:all

  * 1. 从 `Administrative-divisions-of-China` 下载最新的地区信息到 `db/regions` 目录中.
    - db/regions/pca-code.json
  * 2. 将下载后的地区信息导入数据库中

### 如何在View中使用

范例:

    = form_for @article do |f|

      = f.region_select [:province, :city, :district]

      # form_tag
      = region_select :article, :province_id
      = region_select :article, :city_id
      = region_select :article, :district_id

      OR

      = region_select :article, :province
      = region_select :article, :city
      = region_select :article, :district

      = f.submit class: 'btn'

添加前缀名:

    = form_for @article do |f|

      = f.region_select [:province, :city, :district], :prefix => "home"
      = f.region_select [:province, :city, :district], :prefix => "work"


预选则省份:

    = form_for @article do |f|

      = f.region_select [:province, :city, :district], province: "chongqing"

      OR

      = f.region_select [:province, :city, :district], province: "重庆市"

优先选择:

    = form_for @article do |f|

      = f.region_select [:province, :city, :district], priority: { province: ["重庆市"], district: %w(巴南区 北碚区 渝北区) }
