Magento2 getting error after removing/deleting custom module

Magento2 getting error after removing custom module. In this module I have created a custom customer attribute.

ERROR: Class Test\Test\Model\Customer\Attribute\Source\TestAttribute does not exist [] []

Can someone guide me on proper way to remove this module?

Answer 1

Below File is for remove Custom Attribute

<?php
use Magento\Framework\App\Bootstrap;
require DIR . '/app/bootstrap.php';
$bootstrap = Bootstrap::create(BP, $_SERVER);
$obj = $bootstrap->getObjectManager();
$state = $obj->get('Magento\Framework\App\State');
$state->setAreaCode('adminhtml');
$serviceLocator = new \Zend\ServiceManager\ServiceManager();
$serviceLocator->setService(\Magento\Setup\Mvc\Bootstrap\InitParamListener::BOOTSTRAP_PARAM, []);
$provider = new \Magento\Setup\Model\ObjectManagerProvider($serviceLocator);
$dataSetupFactory = new \Magento\Setup\Module\DataSetupFactory($provider);
/** @var \Magento\Framework\Setup\SchemaSetupInterface | \Magento\Framework\Setup\ModuleDataSetupInterface $setup */
$setup = $dataSetupFactory->create();
$eavSetupFactory = new \Magento\Eav\Setup\EavSetupFactory($obj);
$eavSetup = $eavSetupFactory->create(['setup' => $setup]);
// For Remove Customer Attribute
$eavSetup->removeAttribute(\Magento\Customer\Model\Customer::ENTITY, 'ATTRIBUTE_CODE');
// For Remove Product Attribute
$eavSetup->removeAttribute(\Magento\Catalog\Model\Product::ENTITY, 'ATTRIBUTE_CODE');
// For Remove Category Attribute
$eavSetup->removeAttribute(\Magento\Catalog\Model\Category::ENTITY, 'ATTRIBUTE_CODE');

Just run the below Mysql query, it will show you which eav_attribute is using the deleted source class.

SELECT * FROM `eav_attribute` WHERE `source_model` LIKE '%TestAttribute%'

If it is showing an attribute, you need to remove this attribute or set the source_model as NULL.

For removing attributes follow the below answer.

Following is the way I did, might help someone

use Magento\Framework\App\ResourceConnection;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
class UninstallPaymentMethod extends Command
{
    const SETUP_MODULE = 'setup_module';
    protected $eavSetupFactory;
    private $state;
public function __construct(
    \Magento\Framework\View\Element\Template\Context $context,
    \Magento\Eav\Setup\EavSetupFactory $eavSetupFactory,
    ResourceConnection $resourceConnection,
    \Magento\Framework\App\State $state
)
{
    parent::__construct('my:first:command');
    $this->eavSetupFactory = $eavSetupFactory;
    $this->resourceConnection = $resourceConnection;
    $this->state = $state;
}


protected function configure()
   {
       $this->setName('uninstallpaymentmethod:test');
       $this->setDescription('Removing custom customer attribute entry & setup module entry');
   parent::configure();

}
   protected function execute(InputInterface $input, OutputInterface $output)
   {    $this->state->setAreaCode(\Magento\Framework\App\Area::AREA_FRONTEND);
       try {
    $connection  = $this->resourceConnection->getConnection();
    $tableName = $connection->getTableName(self::SETUP_MODULE);

    $whereConditions = [
      $connection->quoteInto('module = ?','Test_Test'),
    ];


    $connection->delete($tableName, $whereConditions);

    $eavSetup = $this->eavSetupFactory->create();

    $entityTypeId = 1; // Find these in the eav_entity_type table
    $eavSetup->removeAttribute($entityTypeId, 'test1');
    $eavSetup->removeAttribute($entityTypeId, 'test2');

    $output->writeln("Removed module attributes successfully.");

   } catch (Exception $e) {
       $output->writeln("There was some issue in removing attibute.");
   }

}
}
