+=head1 NAME
+
+DBIx::Class::DeploymentHandler::Manual::CatalystIntro - Introduction to using DBIx::Class::DeploymentHandler with a new Catalyst Project
+
+=head1 Background
+
+This introduction will use PostgreSQL and Catalyst. Background information on using PostgreSQL with Catalyst can be found at L<Catalyst::Manual::Tutorial::10_Appendices>. This guide will assume that you have some understanding of Catalyst. Please go through the Catalyst tutorials first, if you have not yet done so.
+
+=head1 Database Setup
+
+Start by creating a user catalyst, with password catalyst
+
+ $ sudo -u postgres createuser -P catalyst
+ Enter password for new role: <catalyst>
+ Enter it again: <catalyst>
+ Shall the new role be a superuser? (y/n) n
+ Shall the new role be allowed to create databases? (y/n) n
+ Shall the new role be allowed to create more new roles? (y/n) n
+
+Then create a new database, deploymentintro
+
+ sudo -u postgres createdb -O catalyst deploymentintro
+
+=head1 Create the project
+
+ $ catalyst.pl DeploymentIntro
+ $ cd DeploymentIntro
+ $ perl Makefile.PL
+
+=head1 Create the Schema
+
+ $ script/deploymentintro_create.pl model DB DBIC::Schema DeploymentIntro::Schema \
+ create=static 'dbi:Pg:dbname=deploymentintro' 'catalyst' 'catalyst' '{ AutoCommit => 1 }'
+
+ $ mkdir lib/Schema
+ $ mkdir lib/Schema/Result
+
+Edit out the following from lib/DeploymentIntro/Model/DB.pm:
+
+ __PACKAGE__->config(
+ schema_class => 'DeploymentIntro::Schema',
+
+ connect_info => {
+ dsn => 'dbi:Pg:dbname=deploymentintro',
+ user => 'catalyst',
+ password => 'catalyst',
+ AutoCommit => q{1},
+ }
+ );
+
+Remove deploymentintro.conf and create a new file, deploymentintro_local.pl with the following:
+
+ {
+ name => "DeploymentIntro",
+
+ "Model::DB" => {
+ schema_class => 'DeploymentIntro::Schema',
+
+ connect_info => {
+ dsn => 'dbi:Pg:dbname=deploymentintro',
+ user => 'catalyst',
+ password => 'catalyst',
+ AutoCommit => q{1},
+ }
+ }
+ }
+
+Copy the following program into scripts, under the name deploymentintro_dbicdh.pl
+
+ #!/usr/bin/env perl
+ use strict;
+ use warnings;
+ use feature ":5.10";
+ use aliased 'DBIx::Class::DeploymentHandler' => 'DH';
+ use FindBin;
+ use lib "$FindBin::Bin/../lib";
+ use DeploymentIntro::Schema;
+ use Config::JFDI;
+ my $config = Config::JFDI->new( name => 'DeploymentIntro' );
+ my $config_hash = $config->get;
+ my $connect_info = $config_hash->{"Model::DB"}{"connect_info"};
+ my $schema = DeploymentIntro::Schema->connect($connect_info);
+
+ my $dh = DH->new(
+ {
+ schema => $schema,
+ script_directory => "$FindBin::Bin/../dbicdh",
+ databases => 'PostgreSQL',
+ }
+ );
+
+ sub install {
+ $dh->prepare_install;
+ $dh->install;
+ }
+
+ sub upgrade {
+ die "Please set the version in Schema.pm"
+ unless $dh->schema->schema_version;
+ die "Please update the version in Schema.pm"
+ if ( $dh->version_storage->version_rs->search({version => $dh->schema_version})->count );
+ die "We only support positive integers for versions around these parts."
+ unless $dh->schema_version =~ /^\d+$/;
+
+ $dh->prepare_deploy;
+ $dh->prepare_upgrade;
+ $dh->upgrade;
+ }
+
+ sub current_version {
+ print $dh->database_version. "\n";
+ }
+
+ sub help {
+
+ print qq/
+ usage:
+ install
+ upgrade
+ upgrade-to [version]
+ downgrade-to [version]
+ current-version
+ /;
+
+ }
+
+ help unless $ARGV[0];
+
+ given ( $ARGV[0] ) {
+ when ("install") { install(); }
+ when ("upgrade") { upgrade(); }
+ when ("current-version") { current_version(); }
+ }
+
+Copy the following files into lib/DeploymentIntro/Schema/Result
+
+Cd.pm
+
+ package DeploymentIntro::Schema::Result::Cd;
+ use base qw/DBIx::Class::Core/;
+ __PACKAGE__->load_components(qw/InflateColumn::DateTime/);
+ __PACKAGE__->table('cd');
+ __PACKAGE__->add_columns(
+ 'cdid', { data_type => 'integer' },
+ 'artist', { data_type => 'integer' },
+ 'title', { data_type => 'text' }
+ );
+ __PACKAGE__->set_primary_key('cdid');
+ __PACKAGE__->belongs_to(
+ 'artist' => 'DeploymentIntro::Schema::Result::Artist' );
+ __PACKAGE__->has_many( 'tracks' => 'DeploymentIntro::Schema::Result::Track' );
+
+ 1;
+
+
+Artist.pm
+
+ package DeploymentIntro::Schema::Result::Artist;
+ use base qw/DBIx::Class::Core/;
+ __PACKAGE__->table('artist');
+ __PACKAGE__->add_columns(
+ 'artistid', { data_type => 'integer' },
+ 'name', { data_type => 'text' }
+ );
+ __PACKAGE__->set_primary_key('artistid');
+ __PACKAGE__->has_many( 'cds' => 'DeploymentIntro::Schema::Result::Cd' );
+
+ 1;
+
+
+Track.pm
+
+ package DeploymentIntro::Schema::Result::Track;
+ use base qw/DBIx::Class::Core/;
+ __PACKAGE__->table('track');
+ __PACKAGE__->add_columns(
+ 'trackid', { data_type => 'integer' },
+ 'cd', { data_type => 'integer' },
+ 'title', { data_type => 'text' }
+ );
+ __PACKAGE__->set_primary_key('trackid');
+ __PACKAGE__->belongs_to( 'cd' => 'DeploymentIntro::Schema::Result::Cd' );
+
+ 1;
+
+
+And then edit lib/DeploymentIntro/Schema.pm and add the following above the 1 at the bottom
+
+ use vars qw($VERSION);
+ $VERSION = "1";
+
+
+Now it is just a matter of running
+
+ ./script/deploymentintro_dbicdh.pl install
