Zend - db table not found in another module - php

Question

I have an application with three modules:default, disciplines and plans. In disciplines I have a dbtable which works fine in this module, but if I want to use the dbtable in module plans inside plans_dbtable I get
Class 'Disciplines_Model_DbTable_Disciplines' not found in C:\xampp\htdocs\proiect_mps\application\modules\plans\models\DbTable\Plans.php on line 43.
Require_once and include don't solve the problem. I have Disciplines_Boostrap and Plans_Bootstrap classes written. But it doesn't work. Any ideas?
class Plans_Model_DbTable_Plans extends Zend_Db_Table_Abstract
{
...
public function addPlan(
$year,
$name,
$code,
$domain,
$specialization,
$years)
{
// Id-ul disciplinei
$id_discipline = 0;
$discipline = new Disciplines_Model_DbTable_Disciplines();
....
}
...
}

Since you're using Zend I would not suggest your answer of having a require_once to be the best Basically if you have your configuration nice you dont need to have require_once any place. This might be of a help :
In file application.ini
;Module Configuration
resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.moduleControllerDirectoryName = "controllers"
; Enables Modules bootstrap resource plugin, so each module directory has a bootstrap.php file
resources.modules = 1
and in you BootStrap.php file
protected function _initFrontController() {
// The Zend_Front_Controller class implements the Singleton pattern
$frontController = Zend_Controller_Front::getInstance();
// look in the modules directory and automatically make modules out of all folders found
$frontController->addModuleDirectory(APPLICATION_PATH . '/modules');
// forces the front controller to forward all errors to the default error controller (may already be false by default)
$frontController->throwExceptions(false);
return $frontController;
}
And yes you will need to have Bootstrap.php for your every module
class Disciplines_Bootstrap extends Zend_Application_Module_Bootstrap
{
/**
* This file is ABSOLUTELY NECESSARY to get module autoloading to work.
* Otherwise calls to "$form = new Module_Form_MyForm()" will fail.
*/
}

I think I've resolved it myself. I had to write
require_once(APPLICATION_PATH.'/modules/disciplines/models/DbTable/Disciplines.php');
instead of
require_once '/proiect_mps/application/modules/disciplines/models/DbTable/Disciplines.php';
This also works:
require_once('/../../../disciplines/models/DbTable/Disciplines.php');
for my folder structure.
