数据库FAIL - 数据库模式与当前映射文件不同步 [英] Database FAIL - The database schema is not in sync with the current mapping file

问题描述

任何人都可以解释以下教义模式验证错误消息：

Can anybody explain the following doctrine schema validation error message please:

这里是manyToMany关系中每个实体的yaml ORM定义，与5.9节一起创建的文档。

Here is the the yaml ORM definition of each entity in the manyToMany relationship, created inline with section 5.9 of the documentation.

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逆yaml配置：

And the UserRole inverse yaml configuration:

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: {  }

以下是用户表架构：

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：

The UserRole table schema:

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：

And the UserRoleLookup schema:

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;

正如你所看到的，它是一个非常简单的设置，带有一个查找表来指定用户的角色或给定用户角色中的一组用户。但是，我收到这个令人沮丧的同步错误。我没有阅读任何简明扼要的回答这个问题的在线或在线的内容，我希望有人可以澄清，如果我可以安全的离开这个配置，忽略这个错误？

As you can see, it's a pretty simplistic setup with a look-up table to dictate a user's roles or the set of users in a given user role. However, I'm receiving this frustrating synch error. I've read nothing here or online which answers this question in any concise detail, I was hoping someone could clarify if I am safe to leave this configuration and ignore this error?

推荐答案

运行 php bin / console doctrine：schema：update --dump-sql 将显示SQL中的差异，而无需转储您的数据库。

Running php bin/console doctrine:schema:update --dump-sql wil show you the differences in the SQL without having to dump your db.

您还可以运行以下命令来执行更改：

You can also run the following command to perform the changes:

php bin / console doctrine：schema：update --force --full-database

对于symfony2，它是

For symfony2 it was

php app / console doctrine：schema：update --force --full-database
