DBIx::Class::DeploymentHandler::HandlesVersionStorage - Interface for version storage methods

Typically VersionStorages will be implemented with a simple DBIx::Class::Result. Take a look at the two existing implementations for examples of what you might want to do in your own storage.

  • DBIx::Class::DeploymentHandler::VersionStorage::Standard
  • DBIx::Class::DeploymentHandler::VersionStorage::Deprecated

 $dh->add_database_version({
   version     => '1.02',
   ddl         => $ddl, # can be undef
   upgrade_sql => $sql, # can be undef
 });

Store a new version into the version storage

 my $db_version = $version_storage->database_version

Returns the most recently installed version in the database.

 $dh->delete_database_version({ version => '1.02' })

Deletes given database version from the version storage

 warn q(I can't version this database!)
   unless $dh->version_storage_is_installed

return true if the version storage is installed.
