## Installing the Transformer ## Add it as a hook to your existing rake tasks in Rakefile

Rake::Task['db:schema:load'].enhance do
  Rake::Task['db:transform:load'].invoke
end

Rake::Task['db:schema:dump'].enhance do
  Rake::Task['db:transform:dump'].invoke
end

Rake::Task['db:migrate'].enhance do
  Rake::Task['db:transform'].invoke
end

## Using the Transformer ##

It’s just like migrating, moreso than you probably originally thought.

rails g data_transformation transform_name = make the transform

rake db:transform  = run the unrun transforms
