Problem override from module

[MrGumby]

I added some columns into database for storing additional data and I want to reach that data through adminController, I write Class and Controller override in /modules/my_module/override but when I try to run the controller, it throws exception:

Identifier or table format not valid for class Manufacturer
at line 189 in file classes/ObjectModel.php

As seen, I override Manufacturer class and AdminManufacturerController.

 

I added column 'ean_gpc' into 'ps_manufacturer' table. I store first 7 digits from ean there - this sequence should identifiy manufacturer - I want to be able to edit that sequence when edit manufacturer in back office. Therefore I create

 

class override

<?php
// my_module/override/classes/Manufacturer.php

class Manufacturer extends ManufacturerCore
{
	/** @var string EAN-GPC */
	public $ean_gpc;

	public function __construct($id = null, $id_lang = null)
	{
		self::$definition['fields']['ean_gpc'] = array('type' => self::TYPE_STRING, 'validate' => 'isUnsignedInt', 'size' => 7);
		parent::__construct($id, $id_lang);
	}
}

controller override

<?php
// my_module/override/controllers/admin/AdminManufacturersController.php

class AdminManufacturersController extends AdminManufacturersControllerCore
{
	
	public function renderForm()
	{
		// ...not changed

		$this->fields_form = array(
			'tinymce' => true,
			'legend' => array(
				'title' => $this->l('Manufacturers'),
				'icon' => 'icon-certificate'
			),
			'input' => array(
				// ...added one input nearly at the end of inputs:

				array(
					'type' => 'text',
					'label' => 'EAN-GPC',
					'name' => 'ean_gpc',
					'col' => 2,
					'hint' => $this->l('First 7 digits of EAN13 that identifies manufacturer')
				),

				// ... not changed
				)
			)
		);

		// ... not changed
	}
}

When i write this changes directly int PS core files (just for test), it works, but when I try to override from module, then it fails at following test in ObjectModel:

if (!Validate::isTableOrIdentifier($this->def['primary']) || !Validate::isTableOrIdentifier($this->def['table']))
 			throw new PrestaShopException('Identifier or table format not valid for class '.get_class($this));

Any suggestions?

If anyone is courious,

My brain betrayed me again. He and my eyes. I wrote wrong name of controllers folder inside module/override, and it gets me two days to find it! I should not bought this high DPI display.

 

Anyway, now it is working.

 

Sorry for wasting database.
