NAME

DBIx::Class::DeploymentHandler::CLI - Command line interface for deployment handler

VERSION

Version 0.002

SYNOPSIS

This module provides an command line interface for DBIx::Class::DeploymentHandler.

A sample script using this module looks like:

    #! /usr/bin/env perl

    use strict;
    use warnings;

    use PerlDance::Schema;
    use DBIx::Class::DeploymentHandler::CLI;

    my $schema = PerlDance::Schema->connect('perldance');

    my $dh_cli = DBIx::Class::DeploymentHandler::CLI->new(
        schema => $schema,
        databases => 'MySQL',
        args => \@ARGV,
    );

    if (my $ret = $dh_cli->run) {
       print $ret, "\n";
    }

Let's assume that you name the script dh-cli.

Now you can call the module's methods through commandline parameters:

    ./dh-cli prepare-version-storage
    ./dh-cli install-version-storage

It doesn't matter whether you use dashes ( - ) or underscores ( _ ) in the function name.

BEST PRACTICES

It is often desirable to follow what DeploymentHandler is doing, thus we recommendend to turn on debugging in your dh-cli script:

    BEGIN {
        $ENV{DBICDH_DEBUG} = 1;
    }

ATTRIBUTES

schema

DBIx::Class::Schema object. This parameter is required.

databases

Array reference with database names or single database name as a string. This parameter is required.

It is passed directly to DBIx::Class::DeploymentHandler.

sql_translator_args

Hash reference with parameters for SQL::Translator.

Defaults to:

    {
        add_drop_table => 0,
        producer_args => {
            mysql_version => 5,
        },
    }

SQL::Translator defaults to use data types for totally outdated versions of MySQL, thus we force the major version almost all running instances are using.

This prevents you from ending up with an enum MySQL data type for boolean columns in the schema instead of the boolean one supported by MySQL 5.

It is passed directly to DBIx::Class::DeploymentHandler.

args

Array reference with commandline parameters.

run

Determines method to be run.

version

Prints database and schema version.

database_version

Retrieves schema version from database.

Dies if version storage is missing from database.

Returns 0 if version storage is present, but doesn't contain any records.

schema_version

Retrieves schema version from schema.

custom_upgrade_directory

Returns custom upgrade directory if possible.

prepare_version_storage

install_version_storage

prepare_upgrade

upgrade
