Subdivision Select

subdivision_select is a Rails plugin that extends the functionality of the country_select gem.

When you select a country, a select box for the states or provinces (i.e. subdivisions) is automatically populated for that country.

It loads them via AJAX, but this plugin doesn't require you to write any javascript.

This plugin is called subdivision_select but it could have been called state_selct or province_select

The terminology comes from ISO 3166-2.

The data is provided by the countries gem.

<% form_for(@address) do |f| %>
  <div class="field">
    <%= f.label :country %>
    <%= f.country_select :country %>
  </div>

  <div class="field">
    <%= f.label :subdivision, "State / Province" %>
    <%= f.subdivision_select :subdivision, @address.country %>
  </div>

  <%= f.submit %>
<% end %>

You can also use subdivision_select_tag, if using FormTagHelpers.

This plugin makes no assumptions about what you call the subdivision select, so if you already named your column 'state' or 'province', you can use that instead.

Currently, this plugin assumes your country column is named country, and doesn't provide anyway to override that.

1. Add the following to your Gemfile:

gem "subdivision_select"

2. Add the following to your config/routes.rb:

 mount SubdivisionSelect::Engine, at: 'subdivisions'

(the 'subdivisions' part is necessary, since that path is hardcoded in JS)

3. Add the following to application.js (or whatever your JS digest file is called)

//= require subdivision_select

If you want to work on this gem, fork and clone the repo. We use RSpec and Capybara.

There is a 'dummy app' in spec/dummy you can use for testing.

If you add a feature, please add a feature spec for it, using Capybara.
