Como criar atributo de categoria programaticamente no Magento2

Estou trabalhando na extensão personalizada do magento 2 e preciso criar atributo de categoria programaticamente,

Liste-me as etapas exatas, porque não tenho certeza se o código deve ser colocado no InstallData.php ou onde?

No Magento 2.1 e na versão superior, você também pode consultar o blog para criar atributos programaticamente em detalhes por Criar atributo de categoria personalizada no Magento 2

Você tem que logo abaixo do código dentro

For Magento Version 2.1.*

app / code / {Packagename} / {Modulename} /Setup/InstallData.php

<?php
namespace {Packagename}\{Modulename}\Setup;

use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Catalog\Setup\CategorySetupFactory; 

class InstallData implements InstallDataInterface
{
    /**
    * Category setup factory
    *
    * @var CategorySetupFactory
    */
    private $categorySetupFactory;
    /**
    * Init
    *
    * @param CategorySetupFactory $categorySetupFactory
    */
    public function __construct(CategorySetupFactory $categorySetupFactory)
    {
         $this->categorySetupFactory = $categorySetupFactory;
    }

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
         $installer = $setup;
         $installer->startSetup();
         $categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);
         $entityTypeId = $categorySetup->getEntityTypeId(\Magento\Catalog\Model\Category::ENTITY);
         $attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId);

         $categorySetup->addAttribute(
         \Magento\Catalog\Model\Category::ENTITY, 'custom_attribute', [
            'type' => 'varchar',
            'label' => 'Custom Attribute Description',
            'input' => 'textarea',
            'required' => false,
            'sort_order' => 100,
            'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
            'group' => 'General Information',
            'is_used_in_grid' => true,
            'is_visible_in_grid' => false,
            'is_filterable_in_grid' => true,
         ]
         );
         $installer->endSetup();
    }
}

app / code / {Packagename} / {Modulename} /view/adminhtml/ui_component/category_form.xml

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                </item>
        </argument>
    </field>  
  </fieldset>
</form>

Esta é a versão mais antiga do Magento,

Para Magento versão 2.0. *

Defina o atributo da categoria como abaixo,

app/code/Vendor/Categoryattr/Setup/InstallData.php Arquivo,

<?php
/**
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */

namespace Vendor\CategoryAttribute\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;


class InstallData implements InstallDataInterface
{
    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\Category::ENTITY,
            'custom_attribute',
                      [
                        'type' => 'varchar',
                        'label' => 'Custom Attribute Description',
                        'input' => 'textarea',
                        'required' => false,
                        'sort_order' => 100,
                        'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
                        'group' => 'General Information',
                        'is_used_in_grid' => true,
                        'is_visible_in_grid' => false,
                        'is_filterable_in_grid' => true,
            ]
        );


    }
}

remova a var/generationpasta e execute o comando,

php bin / magento setup: atualize para trabalhar dentro da categoria.

A partir do magento 2.1, você também precisará criar componentes de interface do usuário antes que o campo apareça no administrador.

Crio:

app / code / Vendor / Categoryattr / view / adminhtml / ui_component / category_form.xml

        </field>
    </fieldset>
</form>

Usando o código abaixo, você pode adicionar o atributo de categoria:

No seu módulo, crie a pasta Setup, dentro dele, crie o arquivo InstallData.php

<?php
/**
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace Ibnab\CustomAttribute\Setup;
use Magento\Framework\Module\Setup\Migration;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Catalog\Setup\CategorySetupFactory;

/**
 * @codeCoverageIgnore
 */
class InstallData implements InstallDataInterface
{
    /**
     * Category setup factory
     *
     * @var CategorySetupFactory
     */
    private $categorySetupFactory;

    /**
     * Init
     *
     * @param CategorySetupFactory $categorySetupFactory
     */
    public function __construct(CategorySetupFactory $categorySetupFactory)
    {
        $this->categorySetupFactory = $categorySetupFactory;
    }
    /**
     * {@inheritdoc}
     * @SuppressWarnings(PHPMD.ExcessiveMethodLength)
     */
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $installer = $setup;
         $installer->startSetup();

        $categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);
        $entityTypeId = $categorySetup->getEntityTypeId(\Magento\Catalog\Model\Category::ENTITY);
        $attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId);
         $categorySetup->removeAttribute(
        \Magento\Catalog\Model\Category::ENTITY, 'my_attribute',
    );
        $categorySetup->addAttribute(
        \Magento\Catalog\Model\Category::ENTITY, 'my_attribute', [
             'type' => 'int',
             'label' => 'My Atrribute ',
             'input' => 'select',
             'source' => 'Magento\Eav\Model\Entity\Attribute\Source\Boolean',
             'required' => false,
             'sort_order' => 100,
             'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
             'group' => 'General Information',
        ]
    );
    $idg =  $categorySetup->getAttributeGroupId($entityTypeId, $attributeSetId, 'General Information');
    $categorySetup->addAttributeToGroup(
        $entityTypeId,
        $attributeSetId,
        $idg,
        'my_attribute',
        46
    );
$installer->endSetup();
    }
}

Boas referências acima. Este funcionou bem para mim para criar um atributo para uma categoria. Eu testei isso na v2.0.6.

Ele deve ser colocado em app / code / Vendor / Extension / Setup / InstallData.php

<?php

namespace Vendor\Extension\Setup;

use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface;

class InstallData implements InstallDataInterface
{
    /**
     * EAV setup factory
     *
     * @var EavSetupFactory
     */
    private $eavSetupFactory;

    /**
     * Init
     *
     * @param EavSetupFactory $eavSetupFactory
     */
    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    /**
     * {@inheritdoc}
     */
    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\Category::ENTITY,
            'custom_attribute',
            [
                'group' => 'General Information',
                'type' => 'varchar',
                'label' => 'Custom Attribute',
                'input' => 'text',
                'required' => false,
                'sort_order' => 100,
                'global' => ScopedAttributeInterface::SCOPE_GLOBAL,
                'user_defined' => true,
                'is_used_in_grid' => true,
                'is_visible_in_grid' => false,
                'is_filterable_in_grid' => true,
            ]
        );

        $setup->endSetup();
    }
}

No meu blog, escrevi um exemplo completo de como fazê-lo http://blog.mdnsolutions.com/magento2-create-custom-category-attribute/

<?php

use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $setup->startSetup();
        //Category Attribute Create Script
        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Category::ENTITY,
            'myattributecode' => [
                 'type' => 'varchar',
                 'label' => 'Attribute Title',
                 'input' => 'textarea',
                 'required' => false,
                 'sort_order' => 100,
                 'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
                 'group' => 'General Information',
                 'wysiwyg_enabled' => true,
                 'is_used_in_grid' => true,
                 'is_visible_in_grid' => false,
                 'is_filterable_in_grid' => true,
            ]
        );
        $setup->endSetup();
    }
}
