Question

Is it possible to output the SQL change scripts that \'rake db:migrate\' produces?

Answer 1

You can create a Rake task in lib/tasks/:

namespace :db do
  desc 'Make migration with output'
  task(:migrate_with_sql => :environment) do
    ActiveRecord::Base.logger = Logger.new(STDOUT)
    Rake::Task['db:migrate'].invoke
  end
end

Then call rake db:migrate_with_sql to log the migration.
