KSUID for Ruby

Add this line to your application's Gemfile:

gem "ksuid", github: "mattes/ksuid-ruby"

To automatically use KSUID as primary key in migrations, create the following initializer:

# config/initializers/ksuid.rb
Rails.application.config.generators do |g|
  g.orm :active_record, primary_key_type: :ksuid
end

This fork of michaelherold/ksuid-ruby has a couple of changes:

Previously each model had to be annotated with act_as_ksuid directives (see below). This fork adds native ksuid types for Postgres and SQLite so no annotation is required.

For SQLite this works out of the box because of its dynamic typing.

For Postgres a custom data type is created.

Please note that MySQL does not support custom types, you're stuck with act_as_ksuid.

Old way:

class Event < ApplicationRecord
  include KSUID::ActiveRecord[:foobar]
end

New way:

class Event < ApplicationRecord
  act_as_ksuid :foobar
end

Previously act_as_ksuid and include KSUID::ActiveRecord[:foobar] both blindly initialized ksuid attributes with a new KSUID. Now it only initializes a KSUID for primary keys. I believe this is the expected behavior, much like Postgres' serial auto-increment - it only updates the primary key, not foreign key's for example.

If you marshal a model to JSON or YAML, to_json and to_yaml will convert KSUIDs into strings.
