Specific categories in ZF1 - zend-framework

Question

I have this model:
class Application_Model_Categories extends Zend_Db_Table_Abstract
{
protected $_name = 'categories';
protected $_referenceMap = array(
'Stores' => array (
'columns' => 'store_id',
'refTableClass' => 'Application_Model_Races',
'refColumns' => 'id')
);
}
Then in my controller:
$race = new Application_Model_Races();
$find = $this->race->find(1);
$current = $find->current();
$categories = $current->findDependentRowset('Application_Model_Categories');
this is returning all the categories. i need to apply a filter to return only the categories with parentId = 0
I´m new to ZF1 so if you also see that im getting the data incorrectly in the controller please let me know. thank you

Simply,
$race = new Application_Model_Races();
$find = $this->race->find(1);
$current = $find->current();
$select = $race->getAdapter()->select()->where('parentId = 0');
$categories = $current->findDependentRowset(
'Application_Model_Categories',
null,
$select
);
By providing a Zend_Db_Select object as third argument to findDependentRowset table row method call, you can add as much conditions as you want (even adding limit, setting order, ...).
Edit
Well, you should create a custom Row Class, name it Application_Model_Race for example, or Application_Model_RaceRow.
class Application_Model_RaceRow extends Zens_Db_Table_Row_Abstract
{
public function getParentCategories()
{
$select = $this->getTable()->select()->where('parentId = 0');
return $this->findDependentRowset(
'Application_Model_Categories',
null,
$select
);
}
}
Add a _rowClass to your Application_Model_Races class.
class Application_Model_Races extends Zend_Db_Table_Abstract
{
protected $_rowClass = 'Application_Model_RaceRow';
/** Your old code **/
}
Hope it helps
