はじめに

OneToManyの関係のテーブルにデータを追加(Insert)する。
dtb_product_commentというテーブルを作成し、dtb_productとproduct_idでOneToManyする。

Entity作成～テーブル作成

dtb_product_commentテーブル作成

dtb_product_sizeは以下のイメージ

CREATE TABLE `dtb_product_comment` (
  `id` int(10) UNSIGNED NOT NULL,
  `product_id` int(10) UNSIGNED NOT NULL,
  `comment` longtext DEFAULT NULL,
  `create_date` datetime NOT NULL COMMENT '(DC2Type:datetimetz)',
  `update_date` datetime NOT NULL COMMENT '(DC2Type:datetimetz)',
  `discriminator_type` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

mappedBy/inversedBy

dtb_productが親テーブルでOneToMany dtb_product_commentが子テーブル

親エンティティでmappedBy→子エンティティで指定する自分

app/Customize/Entity/ProductTrait.php

/**
 * @var \Customize\Entity\ProductComment
 *
 * @ORM\OneToMany(targetEntity="Customize\Entity\ProductComment", mappedBy="Product", cascade={"persist","remove"})
 */
private $ProductComments;

子エンティティでManyToOne inversedBy→親エンティティで指定する自分

app/Customize/Entity/ProductComment.php

/**
 * @var \Eccube\Entity\Product
 *
 * @ORM\ManyToOne(targetEntity="Eccube\Entity\Product", inversedBy="ProductComments")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="product_id", referencedColumnName="id")
 * })
 */
private $Product;

テーブル作成

doctrine機能を利用してテーブル作成
(自動で外部キーとかも設定してくれるので)

php bin/console cache:clear --no-warmup
php bin/console eccube:generate:proxies #dtb_product用proxyを作成していない場合
php bin/console doctrine:schema:update --dump-sql
php bin/console doctrine:schema:update --dump-sql --force

作成結果

CREATE TABLE dtb_product_comment (
 id INT UNSIGNED AUTO_INCREMENT NOT NULL, 
 product_id INT UNSIGNED NOT NULL, 
 comment LONGTEXT DEFAULT NULL, 
 create_date DATETIME NOT NULL COMMENT '(DC2Type:datetimetz)', 
 update_date DATETIME NOT NULL COMMENT '(DC2Type:datetimetz)', 
 discriminator_type VARCHAR(255) NOT NULL, 
 INDEX IDX_E9383F534584665A (product_id),

ALTER TABLE dtb_product_comment ADD CONSTRAINT FK_E9383F534584665A FOREIGN KEY (product_id) REFERENCES dtb_product (id);
