NAME
    DBIx::Class::DeploymentHandler - Extensible DBIx::Class deployment

VERSION
    version 0.001000_05

SYNOPSIS
     use aliased 'DBIx::Class::DeploymentHandler' => 'DH';
     my $s = My::Schema->connect(...);

     my $dh = DH->new({
       schema => $s,
       databases => 'SQLite',
       sqltargs => { add_drop_table => 0 },
     });

     $dh->prepare_install;

     $dh->install;

    or for upgrades:

     use aliased 'DBIx::Class::DeploymentHandler' => 'DH';
     my $s = My::Schema->connect(...);

     my $dh = DH->new({
       schema => $s,
       databases => 'SQLite',
       sqltargs => { add_drop_table => 0 },
     });

     $dh->prepare_upgrade(1, 2);

     $dh->upgrade;

DESCRIPTION
    "DBIx::Class::DeploymentHandler" is, as it's name suggests, a tool for
    deploying and upgrading databases with DBIx::Class. It is designed to be
    much more flexible than DBIx::Class::Schema::Versioned, hence the use of
    Moose and lots of roles.

    "DBIx::Class::DeploymentHandler" itself is just a recommended set of
    roles that we think will not only work well for everyone, but will also
    yeild the best overall mileage. Each role it uses has it's own nuances
    and documentation, so I won't describe all of them here, but here are a
    few of the major benefits over how DBIx::Class::Schema::Versioned worked
    (and DBIx::Class::DeploymentHandler::Deprecated tries to maintain
    compatibility with):

    *   Downgrades in addition to upgrades.

    *   Multiple sql files files per upgrade/downgrade/install.

    *   Perl scripts allowed for upgrade/downgrade/install.

    *   Just one set of files needed for upgrade, unlike before where one
        might need to generate "factorial(scalar @versions)", which is just
        silly.

    *   And much, much more!

    That's really just a taste of some of the differences. Check out each
    role for all the details.

METHODS
  prepare_version_storage_install
     $dh->prepare_version_storage_install

    Creates the needed ".sql" file to install the version storage and not
    the rest of the tables

  prepare_install
     $dh->prepare_install

    First prepare all the tables to be installed and the prepare just the
    version storage

  install_version_storage
     $dh->install_version_storage

    Install the version storage and not the rest of the tables

WHERE IS ALL THE DOC?!
    "DBIx::Class::DeploymentHandler" extends
    DBIx::Class::DeploymentHandler::Dad, so that's probably the first place
    to look when you are trying to figure out how everything works.

    Next would be to look at all the roles that fill in the blanks that
    DBIx::Class::DeploymentHandler::Dad expects to be filled. They would be
    DBIx::Class::DeploymentHandler::WithSqltDeployMethod,
    DBIx::Class::DeploymentHandler::WithMonotonicVersions,
    DBIx::Class::DeploymentHandler::WithStandardVersionStorage, and
    DBIx::Class::DeploymentHandler::WithReasonableDefaults.

THIS SUCKS
    You started your project and weren't using
    "DBIx::Class::DeploymentHandler"? Lucky for you I had you in mind when I
    wrote this doc.

    First off, you'll want to just install the "version_storage":

     my $s = My::Schema->connect(...);
     my $dh = DBIx::Class::DeploymentHandler({ schema => $s });

     $dh->prepare_version_storage_install;
     $dh->install_version_storage;

    Then set your database version:

     $dh->add_database_version({ version => $s->version });

    Now you should be able to use "DBIx::Class::DeploymentHandler" like
    normal!

DONATIONS
    If you'd like to thank me for the work I've done on this module, don't
    give me a donation. I spend a lot of free time creating free software,
    but I do it because I love it.

    Instead, consider donating to someone who might actually need it.
    Obviously you should do research when donating to a charity, so don't
    just take my word on this. I like Children's Survival Fund:
    <http://www.childrenssurvivalfund.org>, but there are a host of other
    charities that can do much more good than I will with your money.
