Recursive function to clean an array or hash from keys you don't want to have in there. Useful for scrubbing privacy sensitive information for example. Supports 'safe' mode and 'scrub' mode, respectively meaning to only include the provided fields, or remove the provided fields. Co-authored w/ @Yannickdonners
module DeepScrub
# From a hash or array, scrub or only include specified fields, and
# recursively go through any sub-arrays or sub-hashes.
def deep_scrub(hash_or_array, fields, mode: :safe)
unless [:safe, :scrub].include?(mode)
raise ArgumentError, "mode must be one of :safe or :scrub"
end
if hash_or_array.is_a?(Array)

Storing UUIDs as binary values through Rails 5 and ActiveRecord. The activeuuid gem hasn't been updated for quite some time and with the Rails attributes API this has become relatively easy.
# config/initializers/types.rb
require 'types/uuid'
ActiveModel::Type.register(:uuid, Types::UUID)
