How to specify relationships between tables in ZF2 using ZFcBase - php

Question

i'm new in Zend Framework. I'm working with an application that uses the following db pattern: Controler -> Service -> Mapper.
And i have an entity for each table and a hydrator file. What i need is to join tables in SQL query, but i don´t know how to access the results from the joined table, cause it only feeds the entity of the current table. Here´s my code:
Controller:
$userEntity = new \Portal\Entity\Iamuserdb();
$userEntity->setIamUserDbId($this->params('id'));
$service = $this->getServiceLocator()->get('Portal\Service\Reports');
$user = $service->getUserById($userEntity)
Service (Reports):
protected $iamuserMapper;
public function selectUsers(){
$usuarios = $this->getIamUserMapper()->fetchAllUsers();
return $usuarios;
}
protected function getIamUserMapper()
{
if ($this->iamuserMapper == null) {
$this->iamuserMapper = $this->getServiceManager()->get('Portal\Mapper\Iamuser');
}
return $this->iamuserMapper;
}
Mapper (Iamuser):
public function fetchAllUsers()
{
$select = $this->getSelect();
$select->from('IAMUser')
->join('IAMUser_IAMGroup', 'IAMUser.iamUserDbId=IAMUser_IAMGroup.IAMUser_iamUserDbId', array('IAMUser_iamUserDbId', 'iamGroups_iamGroupDbId'), 'left')
->join('IAMGroup', 'IAMGroup.iamGroupDbId=IAMUser_IAMGroup.iamGroups_iamGroupDbId', array(), 'left');
return $this->select($select);
}
Hydrator:
class Iamuser extends Hydrator
{
protected function getEntity()
{
return 'Portal\Entity\Iamuserdb';
}
protected function getMap()
{
return array(
);
}
}
In my Module.php from the module i have the factory:
'factories' => array(
'Portal\Mapper\Iamuser' => function($sm) {
$dbAdapter = new \Zend\Db\Adapter\Adapter($sm->get('Configuration')['db']);
$mapper = new Mapper\Iamuser();
$mapper->setEntityPrototype(new Entity\Iamuserdb())
->setHydrator(new Mapper\Hydrator\Iamuser())
->setDbSlaveAdapter($dbAdapter)
->setDbAdapter($dbAdapter);
return $mapper;
},
}
See in my mapper i'm joining two tables, but how to fetch these results, since they came from another table and is not feed in Entity class? Thanks in advance

I Solve my problem. All i have to do is return this statement:
return $this->select($select)->getDataSource();
So i skip the hydration results in entities and get raw PDO array, this way i can join tables.
