Magento 产品平面数据错误-PHP致命错误:对非对象调用成员函数reindexAll()

Magento 产品平面数据错误-PHP致命错误:对非对象调用成员函数reindexAll(),magento,indexing,Magento,Indexing,我在MySQL中遇到行限制问题,因为Magento安装中的属性太多,所以我编写了一个扩展,扩展了“Mage\u Catalog\u Model\u Resource\u Product\u Flat\u Indexer”类,使用以下代码将字符限制重写为64 protected function _MySQLCharLimit() { if (!$this->_isFlatTableExists($store)) { $sql = "CREATE TABLE {$t

我在MySQL中遇到行限制问题,因为Magento安装中的属性太多,所以我编写了一个扩展,扩展了“Mage\u Catalog\u Model\u Resource\u Product\u Flat\u Indexer”类,使用以下代码将字符限制重写为64

protected function _MySQLCharLimit()
{
    if (!$this->_isFlatTableExists($store)) {

        $sql = "CREATE TABLE {$tableNameQuote} (n";

        foreach ( $columns as $field => $fieldProp ) {
            if ( $fieldProp['type'] == "varchar(255)" )
            $fieldProp['type'] = "varchar(64)";
                $sql .= sprintf( "  %s,n",
                $this->_sqlColunmDefinition( $field, $fieldProp ) );
        }
        foreach ($addIndexes as $indexName => $indexProp) {
            $sql .= sprintf(' ADD %s,',
            $this->_sqlIndexDefinition( $indexName, $indexProp ) );
        }
        $sql = rtrim($sql, ",");
        $sql = str_replace( "varchar(255)","varchar(64)",$sql );
        $this->_getWriteAdapter()->query( $sql );
    }
}
我从这里得到的

在尝试重新编制索引后,我注意到它将我发送到一个空白页,当我单击“返回”时,“产品平面数据”索引在处理过程中被卡住

我通过SSH从“shell”文件夹运行indexer.php,它报告了以下错误:

PHP致命错误:在第296行Mage/Catalog/Model/Product/Flat/Indexer.PHP中的非对象上调用成员函数reindexAll()

有没有人知道哪里出了问题,或者我如何纠正?谢谢

编辑:完整代码

GDModules\u MySQLCharLimit\u Catalog\u Model\u Resource\u Product\u Flat\u Indexer

config.xml中的重写配置错误。Magento无法实例化它需要的资源模型。啊,好吧,我应该怎么做?使用这个GDModules\u MySQLCharLimit\u Catalog\u model\u resource\u Product\u Flat\u Indexer作为初学者,我想看看是否可以直接实例化资源模型类$foo=新GDModules\u MySQLCharLimit\u Catalog\u Model\u Resource\u Product\u Flat\u Indexer;变量转储(获取类($foo));最常见的情况是,该类位于错误的目录和/或类名中有输入错误。我不确定是否是这样,因为即使我禁用并删除扩展名,它仍然存在错误。
