Magento Admin網格未加載

Question

我正在開發一個模塊。 網格塊未加載，並引發異常。

誰能幫我 ？

Answer 1

將網格文件重命名為Mygrid.php （首字母應大寫），然后在config.xml文件中將“管理路由器”部分更改為：

<admin>
    <routers>
        <adminhtml>
            <args>
                <modules>
                    <security before="Mage_Adminhtml">Somdeb_Security_Adminhtml</security>
                </modules>
            </args>
        </adminhtml>            
    </routers>
</admin>

問題是您也在adminhtml部分中使用了前端路由器聲明。 您應該為adminhtml聲明路由器。

請查看您需要進行的以下更改。 類名app/code/local/Somdeb/Security/Block/Adminhtml/Security/Grid.php

<?php
class Somdeb_Security_Block_Adminhtml_Security_Grid extends Mage_Adminhtml_Block_Widget_Grid
{
   public function __construct()
    {
        parent::__construct();

        // Set some defaults for our grid
        $this->setDefaultSort('id');
        $this->setId('somdeb_security_baz_grid');
        $this->setDefaultDir('asc');
        $this->setSaveParametersInSession(true);
    }

    protected function _getCollectionClass()
    {
        // This is the model we are using for the grid
        return 'Somdeb_Security/baz_collection';
    }

    protected function _prepareCollection()
    {
        // Get and set our collection for the grid
        $collection = Mage::getResourceModel($this->_getCollectionClass());
        $this->setCollection($collection);

        return parent::_prepareCollection();
    }

    protected function _prepareColumns()
    {
        // Add the columns that should appear in the grid
        $this->addColumn('id',
            array(
                'header'=> $this->__('ID'),
                'align' =>'right',
                'width' => '50px',
                'index' => 'id'
            )
        );

        $this->addColumn('name',
            array(
                'header'=> $this->__('Name'),
                'index' => 'name'
            )
        );

        return parent::_prepareColumns();
    }

    public function getRowUrl($row)
    {
        // This is where our row data will link to
        return $this->getUrl('*/*/edit', array('id' => $row->getId()));
    }
}

在您的控制器中，索引動作發生了變化

$this->_addContent($this->getLayout()->createBlock('somdeb_security/adminhtml_mygrid'));

至

$this->_addContent($this->getLayout()->createBlock('security/adminhtml_mygrid'));

在您的config.xm l文件中看到您的塊組名稱id security不是somdeb_security
