I am getting following error message when using Doctrine ORM in Codeigniter. Please help me... ------------------Doctrin Table Defination-------------

abstract class BaseShoes extends Doctrine_Record
{
    public function setTableDefinition()
    {
        $this->setTableName('shoes');
        $this->hasColumn('sku', 'integer', 11, array('primary' => true, 'autoincrement' => false));
        $this->hasColumn('name', 'string', 255);
        $this->hasColumn('keywords', 'string', 255);
        $this->hasColumn('description', 'string');
        $this->hasColumn('manufacturer', 'string', 20);

------------------------ Doctrin Tablo Kodu -------------------

class ShoesTable extends Doctrine_Table

        ->from('Shoes s')
        ->limit($total)
        ->offset($from);

        return $q->execute(array(), Doctrine::HYDRATE_ARRAY);
    }

}

----------------- Model Kodu -----------------

Sanırım bu:

  • Shoes extends BaseShoes - Evet, biz görebilirsiniz
  • BaseShoes extends Doctrine_Record

Doctrine_Record bir sürü şey yapan bir __construct() yöntemi vardır.

Eğer Eğer sınıfların birinde __construct() yöntemini yeniden tanımlamak, kendi üst sınıfında tanımlanmış oluyor __construct() yöntemini geçersiz kılar.


Here :

  • Lütfen Shoes::__construct() yöntemi
  • overrides BaseShoes::__construct()
  • kendisini yok ki, bu Doctrine_Record::__construct() ile aynıdır
  • olan bazı oldukça önemli Doktrin ile ilgili şeyler yapmak gibi görünüyor ;-)


Not tested, but calling the parent's constructor in your own constructor could help :

class Shoes extends BaseShoes
{
    function  __construct() {
        parent::__construct();
        $this->table = Doctrine::getTable('shoes');
    }
    public function getAllShoes()
    {
        $this->table->getAllShoes();
    }
}


And, as a reference, quoting the Constructors and Destructors page of the PHP manual :

Note: Parent constructors are not called implicitly if the child class defines a constructor.
In order to run a parent constructor, a call to parent::__construct() within the child constructor is required.


Still, as a sidenote, I am not sure that defining your own constructor in a Model class, with Doctrine, is such a good idea -- and I've never seen this done, actually, as far as I remember...

Ve burada bir blog-post on the Doctrine's blog , that seems to indicate I'm right (quoting, emphasis mine):

[...] someone asked about the constructor of entities in Doctrine 2 and whether or not it could be used.
I think this is something worth writing about since in Doctrine 1 this was not possible. The constructor was hi-jacked from you and used internally by Doctrine.


And here's the section of Doctrine's 1.2 manual that's relevant : Overriding the Constructor :

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