Overview

SchemaMigrator is a wrapper around ActiveRecord::Migrator that executes all migrations inside a PostgreSQL schema.

Unfortunately this can only execute migrations using the global connection (the connection returned by ActiveRecord::Base.connection).

Examples:

migrator = MultitenancyTools::SchemaMigrator.new('my_schema', 'path/to/migrations')
migrator.migrate
