任何人都可以解释以下原则架构验证错误消息:
下面是 manyToMany 关系中每个实体的 yaml ORM 定义,根据文档的第 5.9 节创建。
Rep\Bundle\ProjectBundle\Entity\User:
type: entity
table: User
fields:
id:
id: true
type: integer
unsigned: true
nullable: false
generator:
strategy: AUTO
username:
type: string
length: 25
fixed: false
nullable: false
salt:
type: string
length: 32
fixed: false
nullable: false
password:
type: string
length: 40
fixed: false
nullable: false
email:
type: string
length: 60
fixed: false
nullable: false
manyToMany:
roles:
targetEntity: UserRole
inversedBy: users
joinTable:
name: UserRoleLookup
joinColumns:
user_id:
referencedColumnName: id
inverseJoinColumns:
user_role_id:
referencedColumnName: id
lifecycleCallbacks: { }
和 UserRole 反向 yaml 配置:
Rep\Bundle\ProjectBundle\Entity\UserRole:
type: entity
table: UserRole
fields:
id:
id: true
type: integer
unsigned: true
nullable: false
generator:
strategy: AUTO
name:
type: string
length: 50
fixed: false
nullable: false
manyToMany:
users:
targetEntity: User
mappedBy: roles
lifecycleCallbacks: { }
这是用户表架构:
CREATE TABLE `User` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(25) COLLATE utf8_unicode_ci NOT NULL,
`salt` varchar(32) COLLATE utf8_unicode_ci NOT NULL,
`password` varchar(40) COLLATE utf8_unicode_ci NOT NULL,
`email` varchar(60) COLLATE utf8_unicode_ci NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
UserRole 表架构:
CREATE TABLE `UserRole` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
和 UserRoleLookup 架构:
CREATE TABLE `UserRoleLookup` (
`user_id` int(11) unsigned NOT NULL,
`user_role_id` int(11) unsigned NOT NULL,
PRIMARY KEY (`user_id`,`user_role_id`),
KEY `user_role_id` (`user_role_id`),
CONSTRAINT `userrolelookup_ibfk_2` FOREIGN KEY (`user_role_id`) REFERENCES `userrole` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
CONSTRAINT `userrolelookup_ibfk_1` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
如您所见,这是一个非常简单的设置,带有一个查找表来指示用户的角色或给定用户角色中的用户集。但是,我收到了这个令人沮丧的同步错误。我在这里或网上没有读到任何简明扼要地回答这个问题的内容,我希望有人能澄清我是否可以安全地离开这个配置并忽略这个错误?
