RefactorMelee : Arg this is terrible code, halp!

gistfile1.rb

# The idea here is that if any of the three tokens are not already
# set, then they should be generated. In order to generate one, it
# must be unique.
def generate_tokens!
  [ :code, :access_token, :refresh_token ].each do |attr|
    next if send(attr)

    token = loop do
      t = SecureRandom.hex(16)
      break t unless self.class.exists?(attr => t)
    end

    send "#{attr}=", token
  end
end

Very similar to code that I wrote (I think you looked at this with me).

def generate_unique_link
  loop do
    self.link = SecureRandom.urlsafe_base64
    break unless self.class.exists?(link: link)
  end
end
