Read Trello cards using Ruby (based on my "Videogames" board)

trello.rb

require 'trello'
require 'json'
require 'base64'
require 'open-uri'

Trello.configure do |config|
  config.developer_public_key = 'KEY'
  config.member_token = 'TOKEN'
end

board = Trello::Board.find('BOARD_ID')
videogames = []

board.lists.each do |list|
  list.cards.each do |card|
    result = {}
    result['title'] = card.name
    result['description'] = card.desc
    result['list'] = list.name
    result['image'] = Base64.encode64(URI.open(card.cover_image.url).read())
    result['tags'] = []
    
    # Labels.
    card.labels.each do |label|
      result['tags'].push(label.name)
    end
    
    # Custom Fields.
    card.custom_field_items.each do |custom_field_item|
      result[custom_field_item.custom_field.name] = custom_field_item.option_value
    end
    
    # URL.
    card.attachments.each do |attachment|
      if attachment.mime_type.empty?
        result['url'] = attachment.url
      end
    end
    
    puts result['title']
    videogames.push(result)
  end
end
