SequelData::Migrate

Run data migrations along side schema migrations for Sequel. Inspired by https://github.com/ilyakatz/data-migrate.

Data migrations are stored in db/data. They act like schema migrations, except they should be reserved for data migrations. For instance, if you realize you need to titleize all your titles, this is the place to do it.

The code is ported from Sequel migration extension.

Install the gem and add to the application's Gemfile by executing:

$ bundle add sequel-data-migrate

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install sequel-data-migrate

Configure your database:

SequelData::Migrate.configure do |config|
  config.db_configuration.host = ENV.fetch('DATABASE_URL')
  config.migration_path = 'db/data_migration' # default value is db/data
end

Add the rake task to Rakelib file in your project:

require 'sequel_data/migrate/rake_task'
task 'data:migrate' => :environment
task 'data:rollback' => :environment

Now you can migrate using rake data:migrate and rollback using rake data:rollback.

To create new migration file, you can use data:create_migration rake task:

bundle exec rake data:create_migration\[<file_name>\]

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
