PluginMigrator

Run all plugin-migrations without installing them as real migrations in every app.

Add to your plugin's Gemfile and bundle:

gem "plugin_migrator"

Rename the "db/migrate" to "db/plugin_migrate".

Run the following rake-task to run all missing plugin-migrations:

bundle exec rake plugin_migrator:migrate

Do rollbacks like so:

bundle exec rake plugin_migrator:rollback
