NAME
DBIx::Class::DeploymentHandler::CLI - Command line interface for deployment handler
VERSION
Version 0.3.0
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-storageIt 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;
}Configuration
We are showing examples for YAML configuration files, but you can also use any other format supported by Config::Any.
Values
- schema_class
- connection
- databases
Files
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}SQL::Translator defaults to use data types for totally outdated versions of MySQL, thus we force the major version almost all running instances are using.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.
config
Configuration object DBIx::Class::DeploymentHandler::CLI::ConfigReader. Created automatically.
config_files
Candidates for configuration files to be used instead of the default ones.
Type: array reference.
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.

Retrieves schema version from schema.
custom_upgrade_directory
Returns custom upgrade directory if possible.
run_custom
Runs a custom upgrade script.

Installs a custom upgrade script.
