Magento 2 安装数据表

Magento 2 安装数据表 

• 第1步：安装脚本
  
  •  首先，我们将为CRUD模型创建数据库表。为此，我们需要插入安装文件

    app/code/Mageplaza/HelloWorld/Setup/InstallSchema.php
    

    　　code:

    <?php
    /**
     * Created by PhpStorm.
     * User: jerryxu
     * Date: 2018/8/11
     * Time: 上午12:22
     */
    
    namespace MchelloworldSetup;
    
    class InstallSchema implements MagentoFrameworkSetupInstallSchemaInterface
    {
    
        public function install(MagentoFrameworkSetupSchemaSetupInterface $setup, MagentoFrameworkSetupModuleContextInterface $context)
        {
            $installer = $setup;
            $installer->startSetup();
            if (!$installer->tableExists('mc_helloworld_post')) {
                $table = $installer->getConnection()->newTable(
                    $installer->getTable('mc_helloworld_post')
                )
                    ->addColumn(
                        'post_id',
                        MagentoFrameworkDBDdlTable::TYPE_INTEGER,
                        null,
                        [
                            'identity' => true,
                            'nullable' => false,
                            'primary'  => true,
                            'unsigned' => true,
                        ],
                        'Post ID'
                    )
                    ->addColumn(
                        'name',
                        MagentoFrameworkDBDdlTable::TYPE_TEXT,
                        255,
                        ['nullable => false'],
                        'Post Name'
                    )
                    ->addColumn(
                        'url_key',
                        MagentoFrameworkDBDdlTable::TYPE_TEXT,
                        255,

                        '64k',
                        [],
                        'Post Post Content'
                    )
                    ->addColumn(
                        'tags',

                        'Post Tags'
                    )
                    ->addColumn(
                        'status',
                        MagentoFrameworkDBDdlTable::TYPE_INTEGER,
                        1,
                        [],
                        'Post Status'
                    )
                    ->addColumn(
                        'featured_image',
                        MagentoFrameworkDBDdlTable::TYPE_TEXT,
                        255,
                        [],
                        'Post Featured Image'
                    )
                    ->addColumn(
                        'created_at',
                        MagentoFrameworkDBDdlTable::TYPE_TIMESTAMP,

                        ['nullable' => false, 'default' => MagentoFrameworkDBDdlTable::TIMESTAMP_INIT],
                        'Created At'
                    )->addColumn(

                    MagentoFrameworkDBAdapterAdapterInterface::INDEX_TYPE_FULLTEXT
                );
            }
            $installer->endSetup();
        }
    }
    

  • 请注意，Magento将在安装模块时首次自动运行此文件。如果之前安装了模块，则需要升级模块并将表创建代码写入该文件夹中的UpgradeSchema.php，并将属性更改为setup_version大于当前安装版本的module.xmlat app/code/Mageplaza/HelloWorld/etc/module.xml。　　
    内容如下：

    <?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="Mc_Mysize" setup_version="1.1.0">
        </module>
    </config>
    

    在module.xml文件中，我们改变了属性1.1.0大于setup_version
文件： app/code/Mageplaza/HelloWorld/Setup/UpgradeSchema.php

    namespace mcHelloWorldSetup;
    
    use MagentoFrameworkSetupUpgradeSchemaInterface;
    use MagentoFrameworkSetupSchemaSetupInterface;
    use MagentoFrameworkSetupModuleContextInterface;
    
    class UpgradeSchema implements UpgradeSchemaInterface
    {
        public function upgrade( SchemaSetupInterface $setup, ModuleContextInterface $context ) {
            $installer = $setup;
    
            $installer->startSetup();
    
            if(version_compare($context->getVersion(), '1.1.0', '<')) {
                if (!$installer->tableExists('mc_helloworld_post')) {
                    $table = $installer->getConnection()->newTable(
                        $installer->getTable('mc_helloworld_post')
                    )

                            '64k',

                        ->addColumn(
                            'status',
                            MagentoFrameworkDBDdlTable::TYPE_INTEGER,
                            1,

                            255,
                            [],
                            'Post Featured Image'
                        )
                        ->addColumn(

                            null,
                            ['nullable' => false, 'default' => MagentoFrameworkDBDdlTable::TIMESTAMP_INIT],
                            'Created At'
                        )->addColumn(
                            'updated_at',
                            MagentoFrameworkDBDdlTable::TYPE_TIMESTAMP,
                            null,
                            ['nullable' => false, 'default' => MagentoFrameworkDBDdlTable::TIMESTAMP_INIT_UPDATE],
                            'Updated At')
                        ->setComment('Post Table');
                    $installer->getConnection()->createTable($table);
    
                    $installer->getConnection()->addIndex(
                        $installer->getTable('mc_helloworld_post'),
                        $setup->getIdxName(
                            $installer->getTable('mc_helloworld_post'),
                            ['name','url_key','post_content','tags','featured_image'],
                            MagentoFrameworkDBAdapterAdapterInterface::INDEX_TYPE_FULLTEXT
                        ),
                        ['name','url_key','post_content','tags','featured_image'],
                        MagentoFrameworkDBAdapterAdapterInterface::INDEX_TYPE_FULLTEXT
                    );
                }
            }
    
            $installer->endSetup();
        }
    }
    

    　　在此之后请运行此命令行：

  • php bin/magento setup:upgrade && php bin/magento setup:static-content:deploy -f

  • InstallSchema.php 用于创建数据库结构。如果要将数据安装到创建的表中，则需要使用 app/code/Mageplaza/HelloWorld/Setup/InstallData.php
    
    请查看Magento中的一些InstallData文件，了解如何使用它。
    

    - vendor/magento/module-tax/Setup/InstallData.php
    - vendor/magento/module-customer/Setup/InstallData.php
    - vendor/magento/module-catalog/Setup/InstallData.php

  • 如上所述，那些安装文件将用于第一次安装模块。如果要在升级模块时更改数据库，请尝试使用UpgradeSchema.php 和  UpgradeData.php。
• 完成创建
