【问题描述】：

我正在尝试使用此 guide 创建自定义类别属性，但它对我不起作用，这是我用于安装数据.php：

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

use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;

class InstallData implements InstallDataInterface
{
  private $eavSetupFactory;

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

  public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
  {
    $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
    $eavSetup->addAttribute(\Magento\Catalog\Model\Category::ENTITY, 'disposizione', [
        'type'     => 'int',
        'label'    => 'Disposizione',
        'input'    => 'boolean',
        'source'   => 'Magento\Eav\Model\Entity\Attribute\Source\Boolean',
        'visible'  => true,
        'default'  => '0',
        'required' => false,
        'global'   => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
        'group'    => 'Display Settings',
    ]);
  }
}

category_form.xml

<?xml version="1.0"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
<fieldset name="display_settings">
    <field name="disposizione">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="dataType" xsi:type="string">boolean</item>
                <item name="formElement" xsi:type="string">checkbox</item>
                <item name="label" xsi:type="string" translate="true">Nome Produttore</item>
                <item name="prefer" xsi:type="string">toggle</item>
                <item name="valueMap" xsi:type="array">
                    <item name="true" xsi:type="string">1</item>
                    <item name="false" xsi:type="string">0</item>
                </item>
                <item name="default" xsi:type="number">0</item>
            </item>
        </argument>
    </field>
</fieldset>
</form>

模块.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
  <module name="Ng_AddAttribute" setup_version="1.0.0" />
</config>

registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
  \Magento\Framework\Component\ComponentRegistrar::MODULE,
  'Ng_AddAttribute',
  __DIR__
);

之后，我使用bin/magento setup:upgrade 升级架构并清除缓存，但没有任何反应，也没有错误。这只是一个尝试，我需要创建两个属性一个文本和一个选择。有人可以帮我吗

【问题讨论】：

您是否在eav_attribute 表中签入attribute_id = disposizione 存在的一行？如果否，则意味着您的安装脚本将不会运行。在此处添加整个模块代码以分析问题所在。
eav_attribute 表中没有新行。这是module.xml的代码<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <module name="Ng_AddAttribute" setup_version="1.0.0" /> </config>
嘿，我的意思是 Ng_AddAttribute 的所有模块文件
我已经编辑了原帖

【解决方案1】：

您的 InstallData.php 文件中缺少命名空间。用下面的代码替换文件内容或添加命名空间。

<?php
namespace Ng\AddAttribute\Setup;

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

use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;

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

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->addAttribute(\Magento\Catalog\Model\Category::ENTITY, 'disposizione', [
            'type'     => 'int',
            'label'    => 'Disposizione',
            'input'    => 'boolean',
            'source'   => 'Magento\Eav\Model\Entity\Attribute\Source\Boolean',
            'visible'  => true,
            'default'  => '0',
            'required' => false,
            'global'   => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
            'group'    => 'Display Settings',
        ]);
    }
}

要让它再次运行，您需要使用如下查询从 setup_module 表中删除该模块的行：

DELETE FROM `setup_module` WHERE `module` LIKE ('%Ng_AddAttribute%');

之后运行 setup:upgrade 命令。

运行：php -dmemory_limit=6G bin/magento setup:upgrade

这将解决您的问题，希望对您有所帮助
