how to create new avatar names

script.rb

# open AvatarUploader and re-define the filename method dynamically- because ewe can't deploy this code, 
# it doesn't work for new records as the processing happens async and can't gauarentee that model.id exists, so we
# should run it only after the record is created.

AvatarUploader.class_eval do
  def filename
    token = OpenSSL::HMAC.hexdigest('SHA256', ENV['AWS_SECRET'], model.id.to_s)
    "#{token}.#{file.extension}"
  end
end

# backfill
Account.find_each do |account|
  account.image.recreate_versions! # a carrierwave method
  account.save!
end


# then we can schedule that as a daily task to backfill the new accounts that are created everyday. Can also use a new
# column :obfuscated and set to true when done.

@ed

Maybe store the obfuscated file name in the column instead of the boolean and return that if present?

I'd go with this, except that it would cause data redundancy, because the name will be stored in image field as well. A boolean is cleaner in this case I think.
