如何解决Magento 2 数据补丁问题
我正在编写一个基本模块，它将为我们销售的物品创建物料清单。该模块包含三个表：氯化器、设备和氯化器_设备。
这些表由 db_schema.xml 生成，如下所示：
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
<table name="chlorinators" resource="default" engine="innodb" comment="Chlorinators Table">
<column xsi:type="smallint" name="chlorinator_id" unsigned="true" nullable="false" comment="Chlorinator ID"/>
<column xsi:type="varchar" name="chlorinator_name" nullable="false" length="1024" comment="Chlorinator Name"/>
<column xsi:type="boolean" name="has_pump" nullable="false" comment="Chlorinator has pump"/>
<constraint xsi:type="primary" referenceId="PRIMARY">
<column name="chlorinator_id"/>
</constraint>
</table>
<table name="equipment" resource="default" engine="innodb" comment="Equipment Table">
<column xsi:type="smallint" name="equipment_id" unsigned="true" nullable="false" comment="Equipment ID"/>
<column xsi:type="varchar" name="equipment_name" nullable="false" length="1024" comment="Equipment Name"/>
<column xsi:type="varchar" name="cutsheet_url" nullable="false" default="" comment="Cutsheet URL - Complete"/>
<column xsi:type="varchar" name="cutsheet_stub" nullable="false" comment="Cutsheet URL - Stub"/>
<constraint xsi:type="primary" referenceId="PRIMARY">
<column name="equipment_id"/>
</constraint>
</table>
<table name="chlorinator_equipment" resource="default" engine="innodb" comment="Chlorinator Equipment Relation Table">
<column xsi:type="smallint" name="id" unsigned="true" nullable="false" identity="true" comment="Chlorinator Equipment ID"/>
<column xsi:type="smallint" name="equipment_id" unsigned="true" nullable="false" comment="Equipment ID"/>
<column xsi:type="smallint" name="chlorinator_id" unsigned="true" nullable="false" comment="Chlorinator ID"/>
<column xsi:type='tinyint' name='quantity' unsigned='true' nullable='false' comment='Quantity' />
<constraint xsi:type="primary" referenceId="PRIMARY">
<column name="id"/>
</constraint>
<constraint xsi:type='foreign' referenceId="FK_CHLOR_ID" table='chlorinator_equipment' column='chlorinator_id' referenceTable='chlorinators' referenceColumn='chlorinator_id' onDelete='CASCADE'/>
<constraint xsi:type='foreign' referenceId="FK_EQUIP_ID" table='chlorinator_equipment' column='equipment_id' referenceTable='equipment' referenceColumn='equipment_id' onDelete='CASCADE'/>
</table>
</schema>
现在我已经创建了表，我希望使用 Magento 的声明式架构将数据输入到表中。就这个问题而言，我只关心将数据输入到“加氯器”表中。
我为加氯器创建了一个模型 (\Jared\Submittal\Model\Chlorinator.PHP)：
<?PHP
namespace Jared\Submittal\Model;
class Chlorinator extends \Magento\Framework\Model\AbstractModel
{
protected function _construct()
{
$this->_init('Jared\Submittal\Model\ResourceModel\Chlorinator');
}
}
还有一个 ResourceModel (\Jared\Submittal\Model\ResourceModel\Chlorinator.PHP)：
<?PHP
class Chlorinator extends \Magento\Framework\Model\ResourceModel\Db\AbstractDb
{
protected function _construct()
{
$this->_init('chlorinators','chlorinator_id');
}
}
此时，我只是想通过这些模型将数据插入到创建的表中，但我没有任何运气。我正在使用数据补丁尝试插入数据，如下所示：
<?PHP
/**
* copyright © Magento,Inc. All rights reserved.
* See copYING.txt for license details.
*/
namespace Jared\Submittal\Setup\Patch\Data;
use Magento\Framework\Setup\Patch\DataPatchInterface;
/**
*/
class AddData implements \Magento\Framework\Setup\Patch\DataPatchInterface
{
/**
* @var \Magento\Framework\Setup\ModuleDataSetupInterface
*/
private $moduleDataSetup;
private $chlorinator;
/**
* @param \Magento\Framework\Setup\ModuleDataSetupInterface $moduleDataSetup
*/
public function __construct(
\Magento\Framework\Setup\ModuleDataSetupInterface $moduleDataSetup,\Jared\Submittal\Model\ResourceModel\Chlorinator $chlorinator
){
/**
* If before,we pass $setup as argument in install/upgrade function,from Now we start
* inject it with DI. If you want to use setup,you can inject it,with the same way as here
*/
$this->moduleDataSetup = $moduleDataSetup;
$this->chlorinator = $chlorinator;
}
/**
* {@inheritdoc}
*/
public function apply()
{
$chlorinatorData = [];
$chlorinatorData['chlorinator_id'] = '1';
$chlorinatorData['chlorinator_name'] = 'chlorinator 1';
$chlorinatorData['has_pump'] = '1';
$this->chlorinator->addData($chlorinatorData);
$this->chlorinator->getResource()->save($this->chlorinator);
}
/**
* {@inheritdoc}
*/
public static function getDependencies()
{
/**
* This is dependency to another patch. Dependency should be applied first
* One patch can have few dependencies
* Patches do not have versions,so if in old approach with Install/Ugrade data scripts you used
* versions,right Now you need to point from patch with higher version to patch with lower version
* But please,note,that some of your patches can be independent and can be installed in any sequence
* So use dependencies only if this important for you
*/
return [];
}
public function revert()
{
$this->moduleDataSetup->getConnection()->startSetup();
//Here should go code that will revert all operations from `apply` method
//Please note,that some operations,like removing data from column,that is in role of foreign key reference
//is dangerous,because it can trigger ON DELETE statement
$this->moduleDataSetup->getConnection()->endSetup();
}
/**
* {@inheritdoc}
*/
public function getAliases()
{
/**
* This internal Magento method,that means that some patches with time can change their names,* but changing name should not affect installation process,that's why if we will change name of the patch
* we will add alias here
*/
return [];
}
public static function getVersion()
{
return "1.0.0";
}
}
我的印象是模型继承了所有 CRUD 操作，但是当我在 AddData.PHP 中调用 create() 时，我收到调用未定义方法的错误。网上的几个模块似乎使用相同的语法和工作，这一事实加剧了我的困惑，例如这个：
https://github.com/cedcommerce/Magento2.3-GraphQl/blob/master/Setup/Patch/Data/AddData.php
我收到的错误已复制到下面，如果您在我的代码中看到导致这些问题的错误，请告诉我：

解决方法
在您链接到 apply 函数的示例中，您使用的是模型，而在您的代码中，您使用的是资源模型。因此，在您的 Jared\Submittal\Setup\Patch\Data\AddData 构造函数中，您应该将 \Jared\Submittal\Model\Chlorinator 用于 $chlorinator 而不是您当前使用的资源模型。
