为此,在/brands/adminhtml_brand/new/我的自定义模块的管理面板中,当我想向数据库添加新条目时,我应该会看到一个页面。我正在关注本教程。我layout.xml的设置正确。

BrandController.php
class Desbest_Brands_Adminhtml_BrandController extends Mage_Adminhtml_Controller_Action
    public function editAction()
        {
            $id = $this->getRequest()->getParam('id', null);
            $model = Mage::getModel('brands/example');
            if ($id) {
                $model->load((int) $id);
                if ($model->getId()) {
                    $data = Mage::getSingleton('adminhtml/session')->getFormData(true);
                    if ($data) {
                        $model->setData($data)->setId($id);
                    }
                } else {
                    Mage::getSingleton('adminhtml/session')->addError(Mage::helper('brands')->__('Example does not exist'));
                    $this->_redirect('*/*/');
                }
            }
            Mage::register('example_data', $model);
            $this->loadLayout();
            $this->getLayout()->getBlock('head')->setCanLoadExtJs(true);
            $this->renderLayout();
      }
 }
