Magento 2 在模块中创建多数据库 table

Question

我已经创建了一个名为 MyCompany\MyModule 的模块。在这个模块中，我想创建大约 3 或 4 db table，例如：greeting_message、greeting_post、greeting_comment。然后，我在 MyCompany\MyModule 下创建了 Setup 文件夹并添加了一个文件 InstallSchema.php 这是代码：

<?php

/**
 * Copyright © 2016 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */

namespace MyCompany\MyModle\Setup;
use Magento\Framework\Setup\InstallSchemaInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;

/**
 * @codeCoverageIgnore
 */
class InstallSchema implements InstallSchemaInterface
{
    /**
     * {@inheritdoc}
     * @SuppressWarnings(PHPMD.ExcessiveMethodLength)
     */
    public function install(SchemaSetupInterface $setup, ModuleContextInterface $context)
    {
        /**
         * Create table 'greeting_message'
         */
        $table = $setup->getConnection()
            ->newTable($setup->getTable('greeting_message'))
            ->addColumn(
                'greeting_id',
                \Magento\Framework\DB\Ddl\Table::TYPE_INTEGER,
                null,
                ['identity' => true, 'unsigned' => true, 'nullable' => false, 'primary' => true],
                'Greeting ID'
            )
            ->addColumn(
                'message',
                \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
                255,
                ['nullable' => false, 'default' => ''],
                'Message'
            )->setComment("Greeting Message table");
        $setup->getConnection()->createTable($table);
    }
}

文件中好像只创建了1个table。那么，有没有一些方法可以在一个模块中创建多数据库 table？

Answer 1

对一个 table 使用复制粘贴代码，对另一个执行相同的操作。以下是所有 table 的内容，请根据您的要求更改列。

<?php

namespace MyCompany\MyModle\Setup;
use Magento\Framework\Setup\InstallSchemaInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;

/**
* @codeCoverageIgnore
*/
class InstallSchema implements InstallSchemaInterface
{
    /**
    * {@inheritdoc}
    * @SuppressWarnings(PHPMD.ExcessiveMethodLength)
    */
    public function install(
        SchemaSetupInterface $setup,
        ModuleContextInterface $context
    )
    {
        /**
         * Create table 'greeting_message'
         */
        $table = $setup->getConnection()
            ->newTable($setup->getTable('greeting_message'))
            ->addColumn(
                'greeting_id',
                \Magento\Framework\DB\Ddl\Table::TYPE_INTEGER,
                null,
                [
                    'identity' => true,
                    'unsigned' => true,
                    'nullable' => false,
                    'primary' => true
                ],
                'Greeting ID'
            )
            ->addColumn(
                'message',
                \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
                255,

                ],
                'Message'
            )
            ->setComment("Greeting Message table");

        $setup->getConnection()->createTable($table);

        /**

        $table = $setup->getConnection()
            ->newTable($setup->getTable('greeting_post'))
            ->addColumn(
                'greeting_id',
                \Magento\Framework\DB\Ddl\Table::TYPE_INTEGER,
                null,

                ],
                'Greeting ID'
            )
            ->addColumn(
                'message',
                \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
                255,
                [
                    'nullable' => false,
                    'default' => ''
                ],
                'Message'
            )->setComment("Greeting Message table");

        $setup->getConnection()->createTable($table);

        /**

        $table = $setup->getConnection()

                ],
                'Greeting ID'
            )
            ->addColumn(
                'message',
                \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,

                ],
                'Message'
            )->setComment("Greeting Message table");

        $setup->getConnection()->createTable($table);
    }
