symfony - SonataDoctrineORMAdminBundle 抛出 array_combine 错误

Question

我有一个多对多关系，它发出警告:

Warning: array_combine(): Both parameters should have an equal number of elements in vendor/sonata-project/doctrine-orm-admin-bundle/Sonata/DoctrineORMAdminBundle/Model/ModelManager.php line 179

相关管理类工作正常，直到使用 Composer 将 SonataDoctrineORMAdminBundle 更新到版本 2.2.4。

我认为问题可能出在我的模型上，但不确定是什么。

bundle\Entity\EntityOne:
    type: entity
    table: entityOne

    fields:
        id:
            type: integer
            id: true
            generator:
                strategy: AUTO
        title:
            type: string
            length: '100'

    oneToMany:
        entityRel:
            targetEntity: EntityRel
            mappedBy: entityOne
            cascade: ["persist", "remove"]

    lifecycleCallbacks: {  }



bundle\Entity\EntityRel:
    type: entity
    table: entityRel
    id:
        entityOne:
            associationKey: true
        entityTwo:
            associationKey: true
    fields:
        amount:
            type: decimal
    oneToOne:
        entityOne:
            targetEntity: EntityOne
        entityTwo:
            targetEntity: EntityTwo
    lifecycleCallbacks: {  }



bundle\Entity\EntityTwo:
    type: entity
    table: entityTwo
    fields:
        id:
            type: integer
            id: true
            generator:
                strategy: AUTO
        name:
            type: string
            length: '100'

    oneToMany:
        entityRel:
            targetEntity: entityRel
            mappedBy: entityTwo
            cascade: ["persist", "remove"]

    lifecycleCallbacks: {  }

这个想法是 EntityRel 通过金额字段连接 EntityOne 和 EntityTwo。两个表之间的每个连接都必须是唯一的，从而强制键是复合的。

有什么想法吗？

您似乎错过了 EntityTwo 的表格:

bundle\Entity\EntityTwo:
type: entity
table: entityTwo
