Class::DBI::Loader - Dynamic definition of Class::DBI sub classes. SYNOPSIS
use Class::DBI::Loader; my $loader = Class::DBI::Loader->new( dsn => "dbi:mysql:dbname", user => "root", password => "", options => { RaiseError => 1, AutoCommit => 0 }, namespace => "Data", additional_classes => qw/Class::DBI::AbstractSearch/, # or arrayref additional_base_classes => qw/My::Stuff/, # or arrayref left_base_classes => qw/Class::DBI::Sweet/, # or arrayref constraint => '^foo.*', relationships => 1, options => { AutoCommit => 1 }, inflect => { child => 'children' }, require => 1 ); my $class = $loader->find_class('film'); # $class => Data::Film my $obj = $class->retrieve(1); use with mod_perl in your startup.pl # load all tables use Class::DBI::Loader; my $loader = Class::DBI::Loader->new( dsn => "dbi:mysql:dbname", user => "root", password => "", namespace => "Data", ); in your web application. use strict; # you can use Data::Film directly my $film = Data::Film->retrieve($id); DESCRIPTION
Class::DBI::Loader automate the definition of Class::DBI sub-classes. scan table schemas and setup columns, primary key. class names are defined by table names and namespace option. +-----------+-----------+-----------+ | table | namespace | class | +-----------+-----------+-----------+ | foo | Data | Data::Foo | | foo_bar | | FooBar | +-----------+-----------+-----------+ Class::DBI::Loader supports MySQL, Postgres and SQLite. See Class::DBI::Loader::Generic. METHODS
new %args additional_base_classes List of additional base classes your table classes will use. left_base_classes List of additional base classes, that need to be leftmost, for example Class::DBI::Sweet (former Catalyst::Model::CDBI::Sweet). additional_classes List of additional classes which your table classes will use. constraint Only load tables matching regex. exclude Exclude tables matching regex. debug Enable debug messages. dsn DBI Data Source Name. namespace Namespace under which your table classes will be initialized. password Password. options Optional hashref to specify DBI connect options relationships Try to automatically detect/setup has_a and has_many relationships. inflect An hashref, which contains exceptions to Lingua::EN::Inflect::PL(). Useful for foreign language column names. user Username. require Attempt to require the dynamically defined module, so that extensions defined in files. By default errors from imported modules are suppressed. When you want to debug, use require_warn. require_warn Warn of import errors when requiring modules. AUTHOR
