Reindexing issue in Magento 2

Question

I added a column in customer_grid_flat table using UpgradeSchema.php . But each time I run the command php bin/magento indexer:reindex this column gets deleted. I cannot figure out why this happen.Please help in this regard. I attached below the customer_eav_attribute and eav_attribute.

Answer 1

Can you try using InstallData instead of Upgrade schema -

<?php 

namespace Namespace\Modulename\Setup; 

use Magento\Customer\Setup\CustomerSetupFactory;
use Magento\Customer\Model\Customer;
use Magento\Eav\Model\Entity\Attribute\Set as AttributeSet;
use Magento\Eav\Model\Entity\Attribute\SetFactory as AttributeSetFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{

    /**
     * @var \Magento\Customer\Setup\CustomerSetupFactory
     */
    private $customerSetupFactory;

    /**
     * @var \Magento\Eav\Model\Entity\Attribute\SetFactor
     */
    private $attributeSetFactory;    

    /**
     * Init
     *
     * @param \Magento\Customer\Setup\CustomerSetupFactory $customerSetupFactory
     */
    public function __construct(
        CustomerSetupFactory $customerSetupFactory,
        AttributeSetFactory $attributeSetFactory
    ) {
        $this->customerSetupFactory = $customerSetupFactory;
        $this->attributeSetFactory = $attributeSetFactory;
    }    

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) {
         /** @var CustomerSetup $customerSetup */
        $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);

        $customerEntity = $customerSetup->getEavConfig()->getEntityType('customer');
        $attributeSetId = $customerEntity->getDefaultAttributeSetId();

        /** @var $attributeSet AttributeSet */
        $attributeSet = $this->attributeSetFactory->create();
        $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);

        $customerSetup->addAttribute(Customer::ENTITY, 'customer_type', [
            'type' => 'int',
            'label' => 'Customer Type',
            'input' => 'select',
            'required' => false,
            'visible' => true,
            'user_defined' => true,
            'sort_order' => 100,
            'position' => 100,
            'is_used_in_grid' => true,
            'system' => 0,
            'source' => 'Magento\Eav\Model\Entity\Attribute\Source\Boolean',
            'adminhtml_only'=>1,
            'default'=>0
        ]);

        $attribute = $customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'customer_type')
        ->addData([
            'attribute_set_id' => $attributeSetId,
            'attribute_group_id' => $attributeGroupId,
            'used_in_forms' => ['adminhtml_customer'],
        ]);

        $attribute->save();
    }
}

Then in your module in customer_columns tag in customer_listing.xml :

<column name="customer_type">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="filter" xsi:type="string">select</item>
                    <item name="editor" xsi:type="string">select</item>
                    <item name="component" xsi:type="string">Magento_Ui/js/grid/columns/select</item>
                    <item name="dataType" xsi:type="string">select</item>
                    <item name="label" xsi:type="string" translate="true">Customer Type</item>
                    <item name="sortOrder" xsi:type="number">100</item>
                </item>
            </argument>
        </column>

Then create app/etc/indexer.xml :

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Indexer/etc/indexer.xsd">
    <indexer id="customer_grid">
        <fieldset name="customer">
            <field name="customer_type" xsi:type="filterable" dataType="int"/>
        </fieldset>
    </indexer>
</config>

Answer 2

You need to use is_used_in_grid as true while creating your customer attribute like below.

$customerSetup->addAttribute(
    Customer::ENTITY,
        'customer_type',
        [
            'type' =>'varchar',
            'label' => 'Customer Type',
            'input' => 'text',
            'required' => false,
            'sort_order' => 101,
            'visiable' => true,
            'position' => 101,
            'system' =>  false,
            'unique' => true,
            'is_used_in_grid' => true,
            'is_visible_in_grid' => false,
            'is_filterable_in_grid' => false,
            'is_searchable_in_grid' => false,
        ]
    );

OR

If you have already created this attribute and need to change the value then you can follow the below steps:

Step 1:

Goto eav_attribute table and search your attribute code customer_type in the column attribute_code. You will get the attribute_id.

Step 2:

Goto customer_eav_attribute table and search the row with attribute_id which you get from step 1.

Step 3:

Now update the columns is_used_in_grid , is_visible_in_grid , is_filterable_in_grid and is_searchable_in_grid to 1.

Step 4:

Flush the cache and run reindex and check.
