My goal is to make an API to get data from the database, but I'm trying to encapsulate using different names for table fields.So the field Cod_Fornec will be codigo, and Des_RazSoc will be razao_social.And when I call to_xml, I only want the select fields to appear in the return.I'm using ActiveRecord as you will see in the sample code, and that's how a managed to do that.\[code\]class Fornecedor < ActiveRecord::Base set_table_name :FORNE set_primary_key :Cod_Fornec alias_attribute :codigo, :Cod_Fornec alias_attribute :razao_social, 
es_RazSoc def attributes { 'codigo' => '0', 'razao_social' => 'nil' } endend\[/code\]It's almost like I want, except for yje type="NilClass" XML attribute for every field.\[code\]<?xml version="1.0" encoding="UTF-8"?><fornecedor> <codigo type="NilClass">3</codigo> <razao-social type="NilClass">AKZO IND E COMERCIO LTDA</razao-social></fornecedor>\[/code\]Is there a way to not get this type attribute at the XML or solve this problem another way ?That's the output without using attributes or alias_attributes.\[code\]<?xml version="1.0" encoding="UTF-8"?><fornecedor> <Cod-Fornec type="integer">3</Cod-Fornec> <Cod-IBGE type="integer" nil="true"></Cod-IBGE> <Cod-RegTri type="integer">1</Cod-RegTri> <Des-Bairro></Des-Bairro> <Des-Cidade></Des-Cidade> <Des-Endere>R JOAO ALFREDO 353</Des-Endere> <Des-Estado></Des-Estado> <Des-Fantas>ORGANON</Des-Fantas> <Des-Observ nil="true"></Des-Observ> <Des-RazSoc>AKZO IND E COMERCIO LTDA</Des-RazSoc> <Flg-Bloque type="boolean">false</Flg-Bloque> <Flg-NaoRepIcm type="boolean">false</Flg-NaoRepIcm> <Nom-Contat></Nom-Contat> <Num-Cep></Num-Cep> <Num-CgcCpf>06056171900071</Num-CgcCpf> <Num-CgfRg>010.360.090.511</Num-CgfRg> <Num-Fax></Num-Fax> <Num-Fone>011 882-450</Num-Fone> <Per-AcrCus type="decimal">0.0</Per-AcrCus> <Per-Descon type="decimal" nil="true"></Per-Descon> <Per-Markup type="decimal">0.0</Per-Markup> <Qtd-DiaPrz type="integer" nil="true"></Qtd-DiaPrz> <Tip-Descon nil="true"></Tip-Descon></fornecedor>\[/code\]
