Question

我在magento后端模块中创建了一个网格，但是出现了错误：

我的网格文件：

public function __construct() {
    parent::__construct();

    $this->setId('logger_grid');
    $this->setUseAjax(FALSE);
    $this->setDefaultSort('log_id');
    $this->setDefaultDir(Varien_Data_Collection::SORT_ORDER_ASC);
    $this->setSaveParametersInSession(TRUE);
}

public function _prepareCollection() {
    $collection = Mage::getModel('logger/logger')->getCollection();
    $this->setCollection($collection);
    return parent::_prepareCollection();
}

public function _prepareColumns() {
    $this->addColumn('log_id', array(
        'header' => Mage::helper('logger')->__('ID'),
        'sortable' => TRUE,
        'index' => 'log_id',
        'editable' => FALSE,
    ));

    $this->addColumn('procedure', array(
        'header' => Mage::helper('logger')->__('Procedure'),
        'sortable' => TRUE,
        'index' => 'procedure',
    ));

    $this->addColumn('type', array(
        'header' => Mage::helper('logger')->__('Type'),
        'sortable' => TRUE,
        'index' => 'type',
        'editable' => FALSE,
    ));

    $this->addColumn('description', array(
        'header' => Mage::helper('logger')->__('Description'),
        'sortable' => TRUE,
        'index' => 'description',
        'editable' => FALSE,
    ));

    $this->addColumn('time', array(
        'header' => Mage::helper('logger')->__('Time'),
        'sortable' => TRUE,
        'index' => 'time',
        'editable' => FALSE,
        'type' => 'datetime',
    ));

    return parent::_prepareColumns();
}

public function getRowUrl($row) {
    return $this->getUrl('*/*/edit', array('id' => $row->getId()));
}

当addColumn（'procedure'，...）被注释掉时，根本没有错误。我不知道问题是什么...我不知道为什么在查询中片段像：'procedure LIKE '%1%')'。 'Procedure'字段是varchar。表结构：

create table `{$installer->getTable('logger/logger')}`(
`log_id` int not null auto_increment, 
`procedure` varchar(254) null,
`type` varchar(254) null, 
`description` text null,
 `time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
primary key(`log_id`));

Answer 1

尝试这样做：

$collection = Mage::getModel('logger/logger');
$this->setCollection($collection);
return parent::_prepareCollection();

magento的核心是getCollection auto，或者：

   $collection = Mage::getModel('logger/logger')->getCollection()
        ->addAttributeToSelect('procedure');

Answer 2

关于你的收藏，试试http://www.magentocommerce.com/wiki/1_-_installation_and_configuration/using_collections_in_magento，如果您需要更多帮助发布sql语句：运用 $收藏 - ＆GT; getSelect（） - ＆GT; __的toString（）;

Answer 3

解决方案非常简单。我需要添加的是->load()所以_prepareCollection（）函数变为：

public function _prepareCollection() {
        $collection = Mage::getModel('logger/logger')->getCollection()->load();
        $this->setCollection($collection);
        return parent::_prepareCollection();
    }

感谢您的回复：）

编辑：

错误更复杂，因为我使用保留字作为列名（'procedure'）。
