NAME

       DBIx::Class::DeploymentHandler::DeployMethod::SQL::Translator::ScriptHelpers

SYNOPSIS

        use DBIx::Class::DeploymentHandler::DeployMethod::SQL::Translator::ScriptHelpers
          'schema_from_schema_loader';

          schema_from_schema_loader({ naming => 'v4' }, sub {
             my ($schema, $version_set) = @_;

             ...
          });

DESCRIPTION

       This package is a set of coderef transforms for common use-cases in migrations.  The subroutines are
       simply helpers for creating coderefs that will work for "PERL SCRIPTS" in
       DBIx::Class::DeploymentHandler::DeployMethod::SQL::Translator, yet have some argument other than the
       current schema that you as a user might prefer.

EXPORTED SUBROUTINES

   dbh($coderef)
        dbh(sub {
          my ($dbh, $version_set) = @_;

          ...
        });

       For those times when you almost exclusively need access to "the bare metal".  Simply gives you the
       correct database handle and the expected version set.

   schema_from_schema_loader($sl_opts, $coderef)
        schema_from_schema_loader({ naming => 'v4' }, sub {
          my ($schema, $version_set) = @_;

          ...
        });

       Any time you write a perl migration script that uses a DBIx::Class::Schema you should probably use this.
       Otherwise you'll run into problems if you remove a column from your schema yet still populate to it in an
       older population script.

       Note that $sl_opts requires that you specify something for the "naming" option.
