I'm writing a basic module that will create a Bill of Materials for items we sell in Magento 2.4.2 CE. The module has three tables: chlorinators, equipment, and chlorinator_equipment.
These tables are generated by db_schema.xml seen below:
<?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>Now that I have created the table, I'm looking to input data into the table using Magento's declarative schema. For the purposes of this question, I am only concerned with entering data into the 'chlorinators' table.
I have created a model for the chlorinators (\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');
}
}And a 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');
}
}At this point, I'm just trying to insert data into the created table via these models, but I'm not having any luck. I'm using a data patch to try to insert the data, which is below:
<?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";
}
}
I was under the impression that models inherited all the CRUD operations, but when I call create() in AddData.php, I get errors for calling an undefined method. My confusion is exacerbated by the fact that several modules online seem to use identical syntax and work, such as this one:
https://github.com/cedcommerce/Magento2.3-GraphQl/blob/master/Setup/Patch/Data/AddData.php
The error I'm getting has been copied below, please let me know if you see an error in my code that's causing these issues:
