Autoguid lets you trivially add human readable uuids to all your models, a whitelisted set of models, or all but a blacklisted set. Indices are automatically created based on a configuration option. There's also a rake task that will backfill these uuids into resources that have already been created.
To get started, include the gem file, run bundle install, then run
rake autoguid:install. Next edit the config/initializers/autoguid.rb
file to specify your configuration. Then migrate your tables with
rake autoguid:migrate:up. Next add the line include Autoguid to all the models that will implement autoguids.
Run rake autoguid:migrate:backfill as required to backfill the existing rows in the database.
rake autoguid:migrate:drop_all will drop all autoguid generated columns and
the data in them.
You can always change the config/initializers/autoguid.rb file
and rerun rake autoguid:migrate:up to add autoguid to new models. This process will delete all existing data, potentially breaking links in your application
