The NGP VAN Ruby Gem

Build Status Test Coverage Code Climate Inline docs Gem Version

An unofficial Ruby wrapper for the NGP VAN RESTful API.

Quick start

Install via Rubygems:

gem install ngp_van

Or add this line to your application's Gemfile:

gem 'ngp_van'

Security

ngp_van is cryptographically signed. To be sure the gem you install hasn’t been tampered with, add the public key as a trusted certificate:

gem cert --add <(curl -Ls https://raw.github.com/christopherstyles/ngp_van/master/certs/christopherstyles.pem)

Then install with:

gem install ngp_van -P MediumSecurity

or if using bundler:

bundle install --trust-policy MediumSecurity

The MediumSecurity trust profile will verify signed gems, but allow the installation of unsigned dependencies.

This is necessary because not all of ngp_vans dependencies are signed, so we cannot use HighSecurity.

Configuration

NGP VAN can be configured using a block:

NgpVan.configure do |config|
  config.application_name = 'MyCampaignApp'

  # See http://developers.everyaction.com/van-api#van-authentication
  config.api_key = 'de286a1a-f2e7-421a-91b8-f8cc8201558f|1'

  # Defaults to "https://api.securevan.com/v4/"
  config.api_endpoint = 'https://intlapi.securevan.com/v4'

  # Defaults to "NGP VAN Ruby Gem #{NgpVan::VERSION}"
  config.user_agent = 'CustomUserAgent'
end

Options can also be set on the configuration object:

% NgpVan.configuration.api_key = 'de286a1a-f2e7-421a-91b8-f8cc8201558f|1'
# => "de286a1a-f2e7-421a-91b8-f8cc8201558f|1"

In a multi-threaded environment you may want to use multiple configurations simultaneously. In that case, pass an appropriately setup configuration class to the client object.

configuration = NgpVan::Configuration.new
configuration.api_key = 'de286a1a-f2e7-421a-91b8-f8cc8201558f|1'
client = NgpVan::Client.new(configuration)
client.district_fields

Making requests

API Methods can be called as module methods or as instance methods on the client.

NgpVan.district_fields
# => [
#      {"districtFieldId"=>1, "name"=>"State", "parentFieldId"=>nil...},
#      {"districtFieldId"=>4, "name"=>"County", "parentFieldId"=>1...}
#    ]

or

client = NpgVan.client
client.district_fields
# => [
#      {"districtFieldId"=>1, "name"=>"State", "parentFieldId"=>nil...},
#      {"districtFieldId"=>4, "name"=>"County", "parentFieldId"=>1...}
#    ]

Development

After checking out the repo, run rake spec to run the tests.

A console task has also been provided to automatically load the NGP VAN environment. Run bin/console for an interactive prompt that will allow you to experiment.

% bin/console
[1] pry(main)> NgpVan::VERSION
# => "x.x.x"
[2] pry(main)> NgpVan.configuration.application_name = 'MyCampaignApplication'
# => "MyCampaignApplication"
[3] pry(main)> NgpVan.configuration.api_key = 'de286a1a-f2e7-421a-91b8-f8cc8201558f|1'
# => "de286a1a-f2e7-421a-91b8-f8cc8201558f|1"
[4] pry(main)> NgpVan.district_fields
# => [
#      {"districtFieldId"=>1, "name"=>"State", "parentFieldId"=>nil...,
#      {"districtFieldId"=>2, "name"=>"County", "parentFieldId"=>1...
#    ]
