[Deprecated] DMZ 1.5.3 (DataMapper OverZealous Edition)

[eluser]PoetaWD[/eluser]
I am having a problem with a Advanced Relationship:

There are 2 model: profile and document

Each profile can have many documents, but only one CPF and RG (those are the most important documents here in Brazil)

Model 1: The Profile

Code:

class Profile extends DataMapper {

    var $has_one = array('ptratamento',
                             'cpf' => array(
                                'class' => 'document',
                                   'other_field' => 'dcpf'
                              ),
                               'rg' => array(
                                'class' => 'document',
                                   'other_field' => 'drg'
                               )
                        );
    
    var $has_many = array('endereco', 'document');

Model 2: The Document

Code:

<?php
class Document extends DataMapper {

    var $has_one = array('tipodocumento', 'profile');    
    var $has_many = array(
        'dcpf' => array(
            'class' => 'profile',
            'other_field' => 'cpf'
        ),
        'drg' => array(
            'class' => 'profile',
            'other_field' => 'rg'
        )
    );

The Controller:

Code:

if($this->input->post('stCPF') != '')
            {
                $cpf = new Document();
                $cpf->stNumero = $this->input->post('stCPF');
                
                $obj->save($cpf, 'cpf');
                
                                
            }
            
            if($this->input->post('stRG') != '')
            {
                $rg = new Document();
                $rg->stNumero = $this->input->post('stRG');
                
                $obj->save_rg($rg);
                
                
            }

The database:

Code:

CREATE TABLE IF NOT EXISTS `documents` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `stNome` varchar(200) NOT NULL,
  `stNumero` varchar(200) NOT NULL,
  `dtEmissao` varchar(200) NOT NULL,
  `stOrgaoEmissor` varchar(200) NOT NULL,
  `stMascara` varchar(200) NOT NULL,
  `stObservacoes` varchar(200) NOT NULL,
  `isAtivo` tinyint(1) NOT NULL DEFAULT '1',
  `rg_id` bigint(20) NOT NULL,
  `cpf_id` bigint(20) NOT NULL,
  `endprincipal_id` bigint(20) NOT NULL,
  `created` datetime NOT NULL,
  `updated` datetime NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=36 ;

The problem is that those documents are not being saved....
