Pumi

Pumi (ភូមិ pronounced Poom, which means Village in Khmer) is an Open Source library containing Geodata for administrative regions in Cambodia including Provinces, Districts, Communes and Villages.

Khmer Village

Demo and API

A JSON API is available to if you're not using Ruby or if you just don't want to install a local copy of the data. The API Start Page also shows a Demo of a UI for for entering any location in Cambodia.

Usage

Rails

Using Pumi with Rails gives you some javascript helpers as well as an API to filter and select Provinces (ខេត្ត), Districts (ស្រុក / ខណ្ឌ), Communes (ឃុំ / សង្កាត់) and Villages (ភូមិ) in both latin and Khmer as seen below and in the Pumi API Start Page

Pumi UI Latin Pumi UI Khmer

To use Pumi with Rails first, require "pumi/rails" in your Gemfile:

gem "pumi", require: "pumi/rails"

Next, mount the Pumi routes in config/routes

# config/routes.rb

mount Pumi::Engine => "/pumi"

Then require the pumi javascript in app/assets/javascripts/application.js

//= require jquery
//= require pumi

Note: jquery is a dependency of pumi and must be required before pumi

Finally setup your view with selects for the province, district, commune and village. See the dummy application for an example and refer to the configuration below.

Plain Ol' Ruby

Rails is not a dependency of Pumi so you can use it with Plain Ol' Ruby if you don't need the javascript and route helpers.

Add this line to your application's Gemfile:

gem "pumi"

And then execute:

$ bundle

  require 'pumi'

  # Get all provinces
  Pumi::Province.all

  # Find a province by id
  Pumi::Province.find_by_id("12")

Configuration

The following html5 data-attributes can be used to configure Pumi.

data-pumi-select-id: A unique id of the select input which is looked up by data-pumi-select-target
data-pumi-select-target: The data-pumi-select-id of the select input in which to update the options when this input is changed
data-pumi-select-collection-url: The url in which to lookup the values for this select input. If this option is not given then no ajax request will be made. Hint: You can use the Rails url helpers here e.g. pumi.districts_path(:province_id => "FILTER")
data-pumi-select-collection-url-filter-interpolation-key: The key value to interpolate for filtering via the collection url. E.g. if you set data-pumi-select-collection-url="/pumi/districts?province_id=FILTER", then a value of "FILTER" here will replace the collection URL with the value of the select input which this select input is the target of
data-pumi-select-collection-label-method: The name of the label method. E.g. data-pumi-select-collection-label-method="name_en" will display the labels in Latin or data-pumi-select-collection-label-method="name_km" will display the labels in Khmer
data-pumi-select-collection-value-method: The name of the value method. E.g. data-pumi-select-collection-value-method="id" will set the value of the select input to the Pumi of the location
data-pumi-select-disabled-target: The target of a parent selector in which to apply the class data-pumi-select-disabled-class to when the input is disabled
data-pumi-select-disabled-class: When the input is disabled this class will be applied to data-pumi-select-disabled-target
data-pumi-select-populate-on-load: Set to true to populate the select input with options on load. Default: false
data-pumi-select-has-hidden-value: Set to true if you also have a hidden field for this input with the same name. Useful for remembering the selection across page reloads. Default: false

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
