my $q = CGI->new;

# create mapper object
my $mapper = CGI::DataObjectMapper->new(

    class_prefix => 'YourApp',
    classes => [ qw( Person Data::Book ) ],
    ignore => [ 'rm' ]
    decode => 'utf8',
);

my $data = $mapper->data; # get mapped object

my $person_name = $data->person->name;
my $person_age = $data->person->age;
my $person_country_name = $data->person->country_name;

my $book_name = $data->data_book->title;
my $book_author = $data->data_book->author;


package YourApp::Person;
use Simo;

sub name{ ac }
sub age{ ac }
sub country_name{ ac }


package YourApp::Data::Book;
use Simo;

sub title{ ac }
sub author{ ac }

# Folloing is post data
# This data is mapping YourApp::Person and YourApp::Data::Book

<form method="post" action="xxxx.cgi" >

DESCRIPTION

This module is data-object mapper for CGI form data.

and decode data if you want.

ACCESSORS

input

is input data. This must be hash ref.

Usually get hash data to use CGI::Vars method

my $q = CGI->new;
$q->Vars;

ignore

is ignored attribute. This must be array ref.

class_prefix

is class prefix.

I want you to specify this value, because Some class names may be conficted.

default_class

is default class when class name cannot get form input attribute name.

<input type="text" name="title" > # class is omited

my $mapper = CGI::DataObjectMapper->new( 
    input => $q->Vars,
    default_class => 'Data::Book',
    classes => [ qw( Person Data::Book ) ],
);

title is attribute of Data::Book

You can get title value this way.

my $title = $data->data_book->title;

classes

is mapped class names. this must be array ref. [ qw( Person Data::Book ) ] etc.

data

is converted data.

You can get object.

$data = $mapper->data;

my $person_name = $data->person->name;
my $person_age = $data->person->age;
my $person_country_name = $data->person->country_name;

my $book_name = $data->data_book->title;
my $book_author = $data->data_book->author;

decode

is charset when data is decoded. 'utf8' etc.

if this is not specify, decode is not done.

Method

build_data

is build data from input information.

This is automatically called when data method is called.

If you set new input data, Please call this method

$mapper->input( { a => 1, b => 2 } );
$mapper->build_data;
my $data = $mapper->data; # data is updated
