[英]Shopware 6 custom plugin, deleting extension on delete parent does not work
I have an extension created following the manual Adding complex data to existing entities .我按照手册Adding complex data to existing entities创建了一个扩展。
My product has with this extension another property like eg product_color
.我的产品具有此扩展的另一个属性,例如product_color
。 On delete the product the prop (entity table) product_color
still remains in the database.删除产品时,prop(实体表) product_color
仍保留在数据库中。
// Migration%123%ProductColor.php
...
public function update(Connection $connection): void
{
$sql = <<<SQL
CREATE TABLE `product_color` (
`id` binary(16) NOT NULL,
`product_id` binary(16) DEFAULT NULL,
`color` tinyint(1) NOT NULL DEFAULT '0',
`created_at` datetime(3) NOT NULL,
`updated_at` datetime(3) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
SQL;
$connection->executeStatement($sql);
}
...
EDIT #1编辑#1
As recommend by @Alex, i've added flags, but the extension keep in the database :正如@Alex 所推荐的,我添加了标志,但扩展名保留在数据库中:
// custom/plugins/MyPlugin/src/Extension/ProductColor/ProductColorExtension.php
class ProductColorExtension extends EntityExtension
{
public function extendFields(FieldCollection $collection): void
{
$collection
->add(
(new OneToOneAssociationField(
'productColor',
'id',
'product_id',
ProductColorExtensionDefinition::class,
true
))->addFlags(new CascadeDelete())
);
}
public function getDefinitionClass(): string
{
return ProductDefinition::class;
}
}
Questions:问题:
There is a flag CascadeDelete
which you can add to your association field:有一个标志CascadeDelete
,您可以将其添加到您的关联字段中:
->addFlags(new CascadeDelete())
This should lead to an ON DELETE CASCADE
entry in the SQL, if you create it with dal:create:schema .如果您使用dal:create:schema创建它,这应该导致 SQL 中的ON DELETE CASCADE
条目。
In addition to setting the CascadeDelete
flag in the entity definition, you need to add a foreign key constraint with your database migration and use CASCADE
for the ON DELETE
subclause.除了在实体定义中设置CascadeDelete
标志外,您还需要在数据库迁移中添加外键约束,并为ON DELETE
子句使用CASCADE
。
ALTER TABLE `product_color`
ADD CONSTRAINT `fk.product_color.product_id` FOREIGN KEY (`product_id`) REFERENCES `product` (`id`) ON DELETE CASCADE ON UPDATE CASCADE;
