【问题描述】：

我正在尝试以 YAML 格式使用 Gedmo 的 tree 扩展，但是当我尝试更新架构时，它返回以下错误：

[Gedmo\Exception\InvalidMappingException]
Unable to find ancestor/parent child relation through ancestor field - [parent] in class -

以下代码是MyEntity.orm.yml文件：

Project\MyBundle\Entity\MyEntity:
    type: entity
    repositoryClass: Gedmo\Tree\Entity\Repository\NestedTreeRepository
    gedmo:
        tree:
            type: nested
    id:
        id:
            type: string
            nullable: false
            generator:
                strategy: UUID
    fields:
        name:
            type: string
            length: 200
        locale:
            type: string
            length: 6
        lft:
            type: integer
            gedmo:
                - treeLeft
        lvl:
            type: integer
            gedmo:
                - treeLevel
        rgt:
            type: integer
            gedmo:
                - treeRight
        root:
            type: string
            nullable: true
            gedmo:
                - treeRoot

    manyToOne:
        parent:
            targetEntity: Project\MyBundle\Model\MyEntityInterface
            inversedBy: children
            joinColumn:
                name: parent_id
                referencedColumnName: id
                onDelete: CASCADE
            gedmo:
                - treeParent
    oneToMany:
        children:
            targetEntity: Project\MyBundle\Model\MyEntityInterface
            mappedBy: parent
            orderBy:
                lft: ASC

【解决方案1】：

不能是接口，必须是实体

找到

targetEntity：项目\MyBundle\Model\MyEntityInterface

改为：

目标实体：项目\MyBundle\Entity\MyEntity
