This project gets the public available vehicle information from the Dutch RDW. It makes the following attributes available:

• brand
• first_color (alias: color)
• second_color
• number_of_cylinders
• cylinder_capacity
• number_of_seats
• fuel_efficiency_main_road
• fuel_efficiency_city
• fuel_efficiency_combined
• energy_label
• bpm (alias: BPM)
• co2_combined
• fuel_type
• stock_price

A configuration is optional, here is an example configuration with explanation in the comments:

RDW.configure do |config|
  # Leave this out of the configuration to not use the cache.
  # This must be a cache object (with read, write and fetch methods).
  config.cache = Rails.cache
  
  # If you are using the cache you can set a custom prefix for cache keys.
  # Default value: rdw_
  config.cache_prefix = 'rdw_data_'
  
  # If set to true, Dutch values will be translated to english.
  # This applies to colors, fuel types and unregistered values
  # For example:
  #   - 'ROOD' will be translated to 'red'
  #   - 'Benzine' will be translated to 'gasoline'
  #   - 'Niet geregistreerd' will be translated to 'unregistered'
  #
  # Default value: false
  config.translate_values = true
end

Add the configuration in the config/initializers folder, name the file rdw.rb (any name will work).

require "RDW"
@vehicle = RDW::CarInfo.new("9KJT45")
@vehicle.brand #=> FERRARI
@vehicle.energy_label #=> G
@vehicle.first_color #=> ROOD
@vehicle.bpm #=> 82168
@vehicle.number_of_cylinders #=> 12
