My Magento version is My config.xml is



My Model in Models/Slider.php is

class Transformer_HomeSlider_Model_Slider extends Mage_Core_Model_Abstract
    public function _construct()

and resource file Models/Resource/Slider.php is

class Transformer_HomeSlier_Model_Resource_Slider extends Mage_Core_Model_Resource_Db_Abstract
    public function _construct()

My database setup script perfectly working when module run i.e table created in database. But When I want to save data on database it says

Fatal error: Call to a member function beginTransaction() on boolean in C:\xampp\htdocs\magento\app\code\core\Mage\Core\Model\Abstract.php on line 313

I Call Model by

$slider_model = Mage::getModel('homeslider/slider');

My controller function is

public function saveAction()
        $slider_model = Mage::getModel('homeslider/slider');
        if ($data = $this->getRequest()->getPost()) {
            try {
                    ->addSuccess($this->__("Your Slider has been saved"));
            } catch (Exception $e) {

I var_dump($data) where I get form-data that is ok. Where is my problem? Thank you.

You have a typo in your resource class name:

Transformer_HomeSlier_Model_Resource_Slider should be Transformer_HomeSlider_Model_Resource_Slider
