Doctrine Fatal Error - Unknown relation alias

Question

I am getting following error message:

Doctrine_Table_Exception: Unknown relation alias shoesTable in /home/public_html/projects/giftshoes/system/database/doctrine/Doctrine/Relation/Parser.php on line 237

I am using doctrine 1.2.2 with Codeigniter

My Code is below: (BaseShoes.php and Shoes.php is auto generated)

------------BaseShoes------------

<?php
// Connection Component Binding
Doctrine_Manager::getInstance()->bindComponent('Shoes', 'sadiqsof_giftshoes');

class Shoes extends BaseShoes

    function  __construct() {
        parent::__construct();
        $this->shoesTable = Doctrine::getTable('Shoes');
    }

    function getAllShoes()
    {
        return $this->shoesTable->getAllShoes();
    }

}

Answer 1

Not sure why you get this specific error, but, judging from Doctrine's manual, you should not define the __construct() method in your Shoes class (that extends BaseShoes, which, itself, extends Doctrine_Record)

Here's the section of Doctrine's manual that says just this : Overriding the Constructor (quoting) :

Doctrine doesn't allow you to override the Doctrine_Record::__construct() method but provides an alternative
[...]

(I didn't copy-paste everything : there is more interesting stuff there ;-) )

Answer 2

Removing the constructor without doing something with the code you've removed probably won't help.

I am new to Doctrine, but I'd had the same error recently (I think for different reasons). I wonder if the class attribute $this->shoesTable is taken to mean a foreign relation, which would explain the error message. In any case, you probably don't want to have a table method in a row class, so I would be inclined to do this:

Doctrine_Core::getTable('Shoes')->getAllShoes();

I know it's unlikely you're still awaiting this, but if you want to continue the dialogue, post your calling code.
