zend doctrine couldn't find class - php

Question

Executing in method checkUnique the line $res=$select->fetchArray(); in the following class I get an error which I cannot solve.
I think it is due to the naming conventions zend autoloader
class Twit_Model_Owners extends Twit_Model_BaseOwners {
function checkUnique($username) {
$con = Doctrine_Manager::getInstance()->connection();
$select = $con->createQuery();
$select->from($this->getTable()->getTableName(), array('loginName'))
->where('loginName=?', $username);
$res=$select->fetchArray();
if (empty($res)) {
return true;
}
return false;
}
}
The exception:
Application error
Exception information:
Message: Couldn't find class Owners

I can instantiate models without problem. This is the code i use to generate models:
Doctrine::generateModelsFromDb('/var/www/twit/application/models', array('zenddb'), array(
'baseClassesDirectory' => '',
'classPrefix' => 'Twit_Model_',
'classPrefixFiles' => false
));
Furthermore, if you want, you can visit the sample page here and get the error by yourself here.

Answer 1

It seems that Doctrine does not want the name of the table, as returned by $this->getTable()->getTableName()
but the name of the object (in my case Twit_Model_Owners)
personally I cannot understand such choice (to abstract is ok but at least the name of the tables in the query builder should be mantained), but I complain.
