Question
I am creating a product attribute for sorting which will be int type : where I am getting following error:
PHP Fatal error: Uncaught Error: Class 'Magento\Catalog\Model\Resource\Eav\Attribute' not found in /opt/bitnami/apps/magento/htdocs/app/code
/Vendor/Module/Setup/InstallData.php:57
Here is my Vendor/Module/Setup/InstallData.php
<?php
namespace Vendor\Module\Setup;
use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
/**
* @codeCoverageIgnore
*/
class InstallData implements InstallDataInterface
{
/**
* EAV setup factory
*
* @var EavSetupFactory
*/
private $eavSetupFactory;
/**
* Init
*
* @param EavSetupFactory $eavSetupFactory
*/
public function __construct(EavSetupFactory $eavSetupFactory)
{
$this->eavSetupFactory = $eavSetupFactory;
}
/**
* {@inheritdoc}
* @SuppressWarnings(PHPMD.ExcessiveMethodLength)
*/
public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
/** @var EavSetup $eavSetup */
$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
/**
* Add attributes to the eav/attribute
*/
$eavSetup->addAttribute(
\Magento\Catalog\Model\Product::ENTITY,
'sorting_attribute',
[
'type' => 'int',
'backend' => '',
'frontend' => '',
'label' => 'Sorting Attribute',
'input' => '',
'class' => '',
'source' => '',
'global' => \Magento\Catalog\Model\Resource\Eav\Attribute::SCOPE_GLOBAL,
'visible' => true,
'required' => false,
'user_defined' => false,
'default' => 0,
'searchable' => false,
'filterable' => false,
'comparable' => false,
'visible_on_front' => false,
'used_in_product_listing' => true,
'unique' => false,
'apply_to' => ''
]
);
}
}
Solution
Change the code in module.xml file to this.
<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
<module name="Vendor_Module" setup_version="1.0.0">
<sequence>
<module name="Magento_Catalog"/>
</sequence>
</module>
</config>
Replace your code with this code in InstallData.php.
namespace Vendor\Module\Setup;
use Magento\Catalog\Model\Product;
use Magento\Catalog\Model\Product\Type;
use Magento\Catalog\Model\Resource\Eav\Attribute;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
/**
* @codeCoverageIgnore
*/
class InstallData implements InstallDataInterface
{
/**
* EAV setup factory
*
* @var EavSetupFactory
*/
private $eavSetupFactory;
/**
* Init
*
* @param EavSetupFactory $eavSetupFactory
*/
public function __construct(EavSetupFactory $eavSetupFactory)
{
$this->eavSetupFactory = $eavSetupFactory;
/* assign object to class global variable for use in other class methods */
}
/**
* {@inheritdoc}
* @SuppressWarnings(PHPMD.ExcessiveMethodLength)
*/
public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
$setup->startSetup();
/** @var EavSetup $eavSetup */
$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
/**
* Add attributes to the eav/attribute
*/
$eavSetup->addAttribute(
\Magento\Catalog\Model\Product::ENTITY,
'sorting_attribute',
[
'type' => 'int',
'backend' => '',
'frontend' => '',
'label' => 'Sorting Attribute',
'input' => 'text',
'class' => '',
'source' => '',
'global' => 1,
'visible' => true,
'required' => false,
'user_defined' => true,
'default' => 0,
'searchable' => false,
'filterable' => false,
'comparable' => false,
'visible_on_front' => true,
'used_in_product_listing' => true,
'unique' => false,
'apply_to' => 'simple,configurable,virtual,bundle,downloadable,grouped',
'group'=> 'General'
]
);
$setup->endSetup();
}
}
OTHER TIPS
Change: \Magento\Catalog\Model\Resource\Eav\Attribute::SCOPE_GLOBAL
to \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL
.
//'global' => \Magento\Catalog\Model\Resource\Eav\Attribute::SCOPE_GLOBAL, <= Remove this line
'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
