Hi guys i have a class:

class Marca extends DataObject {

   static $db = array(
'Nomemar' => 'Varchar(255)'
);

static $has_many = array(
    'Modelos' => 'Modelo'   
);

static $belongs_many_many = array(
      'Produtos' => 'Produto'       
);

static $searchable_fields = array(
'Nomemar'
);

static $summary_fields = array(
'Nomemar' => 'Nome'
);

function getCMSFields()
{
    $fields = parent::getCMSFields();
       $fields->push(new TextField('Nomemar','Nome Marca')
      );

return $fields;
}

function forTemplate() { return $this->Nomemar; }
}

and:

class Modelo extends DataObject {

static $db = array(
   'Nomemod' => 'Varchar(255)'
);

static $has_one = array(
      'Marcas' => 'Marca'
);

/*
static $belongs_many_many = array(
'Produtos' =>'Produto'
);*/

static $summary_fields = array(
'Nomemod' => 'Nome Modelo',
'Nomemar'=>'NomeMARCAS'
);

function getCMSFields()
   {
$fields = parent::getCMSFields();

$fields ->push(new TextField('Nomemod','Nome Modelo'));
   
$modulesMarcas = new HasOneDataObjectManager(
$this,
'Marcas',
'Marca',
array(
    'Nomemar' => 'Nome'
),
'getCMSFields'
);

$fields->removeFieldFromTab('Root', 'Main'); // replace the tab with MMDOM tab
$fields->push( $modulesMarcas );
   
return $fields;

   }
   
   function forTemplate() { return $this->Nomemod; }
}

and another class Product

where i have

$managermod = new ManyManyDataObjectManager(
    $this, // Controller
    'Modelos', // Source name
    'Modelo', // Source class
    array('Nomemod' => 'Nome Modelo',
          'MarcasID' => 'Nome Marcas'
    ),
    'getCMSFields' );
   
    $f->removeFieldFromTab('Root', 'Modelos'); // replace the tab with MMDOM tab
    $f->addFieldToTab('Root.Modelos', $managermod);

so i want have 'MarcasNomemar' => 'Nome Marcas' instead 'MarcasID' => 'Nome Marcas' in my backoffice

sugestions...

dont worked...

so... this code:

public function getMarcasNomemar() {
if($m = $this->Marcas()) {
return $m->Nomemar;
}
return false;
}

i have put in... class Marca?

and, this

array (
'MarcasNomemar' => 'Nome Marcas'
);

go to "ManyManyDataObjectManager" right?

oh yeah...

Awesome... thank's UncleCheese! Already worked....
