mysql - Doctrine ORM 不会在从 YaML 规范生成的数据库中创建外键

Question

我正在 Symfony 中使用 Doctrine 。我已使用 YaML 指定了我的数据库实体。我能够从 YaML 文件生成数据库 - 然而，令我恐惧的是，当我检查生成的表时 - 一些实体正在丢失外键引用等。

Doctrine 似乎默默地失败了，因为屏幕上没有发出任何错误，并且 doctrine:schema:update --force 任务运行并报告它已成功完成。

以下是此类实体的示例:

AppBundle\Entity\User:
    type: entity
    table: user
    repositoryClass: UserRepository
    id:
        id:
            type: integer
            generator: { strategy: AUTO }

    manyToOne:
        user_type:
            targetEntity: UserType
            joinColumn:
                name: user_type_id
                referencedColumnName: id
                nullable: false
                onDelete: RESTRICT
                onUpdate: CASCADE

    manyToOne:
        user_title:
            targetEntity: UserTitle
            joinColumn:
                name: user_type_id
                referencedColumnName: id
                nullable: false
                onDelete: RESTRICT
                onUpdate: CASCADE

    oneToMany:
        actions:
            targetEntity: UserAction
            mappedBy: User

    oneToMany:
        type_roles:
            targetEntity: UserTypeRole
            mappedBy: User

    uniqueConstraints:
        idxu_user_lname_eml:
            columns: [last_name, user_email]

    indexes:
        idx_user_name:
            columns: [last_name, first_name]
        idx_user_email:
            columns: user_email            


    fields:
        first_name:
            type: string
            length: 32
            nullable: false
            unique: false

        middle_name:
            type: string
            length: 32
            nullable: true
            unique: false 

        last_name:
            type: string
            length: 64
            nullable: false
            unique: false     

        email:
            type: string
            length: 32
            column: user_email
            unique: true
            options:
                fixed: true
                comment: User's email address

        address_line1:
            type: string
            length: 128
            nullable: false

        address_line2:
            type: string
            length: 128
            nullable: true

        address_line3:
            type: string
            length: 128
            nullable: true

        town_city:
            type: string
            length: 128
            nullable: true

        county_district:
            type: string
            length: 128
            nullable: true

        state_region:
            type: string
            length: 128
            nullable: true

        post_zipcode:
            type: string
            length: 12
            nullable: true

        country:
            type: string
            length: 128
            nullable: true

        login_count:
            type: integer
            nullable: false
            options:
                unsigned: true
                default: 0

        last_login:
            type: datetime
            nullable: true

这是根据上述规范生成的表格:

任何人都可以看到我做错了什么，这阻止了建立外部关系吗？

本节:

manyToOne:
    user_type:
        targetEntity: UserType
        joinColumn:
            name: user_type_id
            referencedColumnName: id
            nullable: false
            onDelete: RESTRICT
            onUpdate: CASCADE

manyToOne:
    user_title:
        targetEntity: UserTitle
        joinColumn:
            name: user_type_id
            referencedColumnName: id
            nullable: false
            onDelete: RESTRICT
            onUpdate: CASCADE

oneToMany:
    actions:
        targetEntity: UserAction
        mappedBy: User

oneToMany:
    type_roles:
        targetEntity: UserTypeRole
        mappedBy: User

应该看起来像这样:

manyToOne:
    user_type:
        targetEntity: UserType
        joinColumn:
            name: user_type_id
            referencedColumnName: id
            nullable: false
            onDelete: RESTRICT
            onUpdate: CASCADE
    user_title:
        targetEntity: UserTitle
        joinColumn:
            name: user_type_id
            referencedColumnName: id
            nullable: false
            onDelete: RESTRICT
            onUpdate: CASCADE

oneToMany:
    actions:
        targetEntity: UserAction
        mappedBy: User
    type_roles:
        targetEntity: UserTypeRole
        mappedBy: User

在 YaML 中，当使用相同名称定义多个键时，它只会覆盖该键之前的值。
