A quick script I wrote to help pick a winner for a friend's tumblr giveaway

giveaway.rb

require 'tumblr_client'
Tumblr.configure do |config|
  config.consumer_key = "conumer_key"
  config.consumer_secret = "consumer_secret"
  config.oauth_token = "oauth_token"
  config.oauth_token_secret = "oauth_token_secret"
end
client = Tumblr::Client.new
posts = client.posts("blog", id: id, notes_info: true)
notes = posts["posts"].first["notes"]
notes = notes.uniq { |note| note["blog_name"] } # prevent multiple entries
notes = notes.delete_if do |note|
  note["blog_name"] == "authors blog" ||        # prevent author from winning
  note["type"] != "reblog"                      # allow only reblogs to win
end
winner = notes.shuffle.first
puts "#{winner["blog_name"]} - #{winner["type"]}"
