Question

我使用链接表在两个实体之间存在多对多的关系。我的问题是，在删除时，似乎是另一个不应删除的实体正在尝试删除，而不是链接表中的行。

我有以下表格：

    CREATE TABLE `hotel_property` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`location_id` int(11) DEFAULT NULL,
`tier_id` int(11) DEFAULT NULL,
`title` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`description` longtext COLLATE utf8_unicode_ci,
PRIMARY KEY (`id`)
)

CREATE TABLE `hotel_amenity` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`value_str` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
`is_active` tinyint(1) NOT NULL,
PRIMARY KEY (`id`),
)

和链接表：

CREATE TABLE `hotel_property_amenity` (
`property_id` int(11) NOT NULL,
`amenity_id` int(11) NOT NULL,
PRIMARY KEY (`property_id`,`amenity_id`),
KEY `IDX_197E8A3E549213EC` (`property_id`),
KEY `IDX_197E8A3E9F9F1305` (`amenity_id`),
CONSTRAINT `FK_197E8A3E9F9F1305` FOREIGN KEY (`amenity_id`) REFERENCES `hotel_amenity` (`id`),
CONSTRAINT `FK_197E8A3E549213EC` FOREIGN KEY (`property_id`) REFERENCES `hotel_property` (`id`)
)

所以，我试图删除一个属性，该属性也应该删除hotel_property_amenity但我的日志显示正在删除hotel_amenity（或者它正在尝试但是它显然会引发约束违规）

日志：

500 An exception occurred while executing 'DELETE FROM hotel_amenity WHERE id = ?' with params [67]

。

Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`test`.`hotel_property_amenity`, CONSTRAINT `FK_197E8A3E9F9F1305` FOREIGN KEY (`amenity_id`) REFERENCES `hotel_amenity` (`id`))

Doctrine Property Entity（我认为我可能错了）：

/**
 * @var ArrayCollection
 *
 * @ORM\ManyToMany(
 *        targetEntity="Test\Hotel\Entity\Amenity",
 *        indexBy="type",
 *        orphanRemoval=true,
 *        fetch="EXTRA_LAZY",
 *        cascade={"persist", "refresh", "remove"})
 * @ORM\JoinTable(name="hotel_property_amenity",
 *      joinColumns={@ORM\JoinColumn(name="property_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="amenity_id", referencedColumnName="id")})
 *
 * @ORM\OrderBy({"featured" = "DESC", "sortPosition" = "ASC"})
 */
protected $amenities;

有没有人知道我哪里出错了？

问题最终是级联=＆＃34;删除＆＃34;。删除后，桥接表中的行将被处理，关联的实体将保持不变。

Doctrine - ManyToMany关系没有正确删除
