There is same problem (undefined index) for find() function Zend_Db_Table_Abstract on line 1265

Can you please provide a bit more information on how your modified class looks like? I am not able to reproduce this error.

Hi, Could you please take a look to code below?

<?php

/*

CREATE TABLE `test`.`accounts` (
`id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`name` VARCHAR( 5 ) NOT NULL
) ENGINE = MYISAM ;

INSERT INTO `test`.`accounts` (
`id` ,
`name`
)
VALUES (
'1234', 'test'
);


CREATE TABLE `test`.`bugs` (
`id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`reported_by` INT NOT NULL
) ENGINE = MYISAM ;

INSERT INTO `test`.`bugs` (
`id` ,
`reported_by`
)
VALUES (
'1', '1234'
);

*/

require_once 'Zend/Db/Table/Abstract.php';

$db_config = array(
    'adapter'         => 'PDO_MYSQL',
    'params' => array (
        'dbname' => 'test',
        'host'   => 'localhost',
        'username' => 'root',
        'password' => '',
    ),
);

$db = Zend_Db::factory($db_config['adapter'], $db_config['params']);

$db->setFetchMode(Zend_Db::FETCH_ASSOC);
Zend_Db_Table_Abstract::setDefaultAdapter($db);

class Accounts extends Zend_Db_Table_Abstract
{
    protected $_name            = 'accounts';
    protected $_dependentTables = array('Bugs');
    
    protected $_cols = array('id', 'name');
    protected $_primary = 'id';
}


class Bugs extends Zend_Db_Table_Abstract
{
    protected $_name            = 'bugs';
    protected $_referenceMap    = array(
        'Reporter' => array(
            'columns'           => 'reported_by',
            'refTableClass'     => 'Accounts',
            'refColumns'        => 'id'
        ),
    );
    protected $_cols = array('id', 'reported_by');
    protected $_primary = 'id'; 
}


$accountsTable = new Accounts();
$accountsRowset = $accountsTable->find(1234);
$user1234 = $accountsRowset->current();
$bugsReportedByUser = $user1234->findDependentRowset('Bugs');

var_dump($bugsReportedByUser->toArray());

and run it

Thanks, now I am able to reproduce this error.

Your tables are a bit different than these in the manual.

This could be a possible fix but I need to verify to not break backward compatibility and/or any unittest.

I add $_cols and $_primary to prevent "DESCRIBE table" request which called from _setupMetadata(). But you want to change this behavior. Is it possible to fix the bug without calling _setupMetadata()?

Thanks.
