Question

我从Symfony2和Doctrine开始。既然我有第一个行动，包括通过运行doctrine进行数据库交互，我想为两个实体创建一个manyToOne关联。我从一开始就开始使用YAML中的Doctrine配置文件定义模型。

E.g。（已包括manyToOne协会）

Carsetup\MainBundle\Entity\VehicleWheelCombination:
    type: entity
    table: vehicle_wheel_combination
    indexes:
        vehicle_wheel_combinations_rim:
            columns:
                - rim_id
        vehicle_wheel_combinations_spacer:
            columns:
                - spacer_id
        vehicle_wheel_combinations_tyre:
            columns:
                - tyre_id
        vehicle_wheel_combinations_vehicles:
            columns:
                - vehicle_id
    id:
        id:
            type: integer
            nullable: false
            unsigned: false
            comment: ''
            id: true
            generator:
                strategy: IDENTITY
    fields:
        streetLegal:
            type: boolean
            nullable: false
            comment: ''
            column: street_legal
    manyToOne:
        rim:
            targetEntity: Rim
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
                rim_id:
                    referencedColumnName: id
            orphanRemoval: false
        spacer:
            targetEntity: Spacer
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
                spacer_id:
                    referencedColumnName: id
            orphanRemoval: false
        tyre:
            targetEntity: Tyre
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
                tyre_id:
                    referencedColumnName: id
            orphanRemoval: false
        vehicle:
            targetEntity: Vehicle
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
                vehicle_id:
                    referencedColumnName: id
            orphanRemoval: false
    manyToOne:
        rating:
            targetEntity: Rating
            cascade: {  }
            mappedBy: null
            inversedBy: null
            orphanRemoval: false
    lifecycleCallbacks: {  }

基于这些配置，我生成了实体。当我现在重新生成实体时，没有创建关联的getter或setter。使用的命令：

php app/console doctrine:generate:entities Carsetup/MainBundle/Entity/VehicleWheelCombination

是的，我可以直接在实体中创建关联，但我无法理解的是：配置文件的实际原因是什么？为什么我不首先创建实体？或者我做错了什么？

谢谢！

我得到了它的工作。我不想保留其他可能遇到类似问题的orm.yml文件。这是我关注实体的工作原则配置文件：

Carsetup\MainBundle\Entity\VehicleWheelCombination:
    type: entity
    table: vehicle_wheel_combination
    indexes:
        vehicle_wheel_combinations_rim:
            columns:
                - rim_id
        vehicle_wheel_combinations_spacer:
            columns:
                - spacer_id
        vehicle_wheel_combinations_tyre:
            columns:
                - tyre_id
        vehicle_wheel_combinations_vehicles:
            columns:
                - vehicle_id
    id:
        id:
            type: integer
            nullable: false
            unsigned: false
            comment: ''
            id: true
            generator:
                strategy: IDENTITY
    fields:
        streetLegal:
            type: boolean
            nullable: false
            comment: ''
            column: street_legal
    manyToOne:
        rim:
            targetEntity: Rim
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
                rim_id:
                    referencedColumnName: id
            orphanRemoval: false
        spacer:
            targetEntity: Spacer
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
                spacer_id:
                    referencedColumnName: id
            orphanRemoval: false
        tyre:
            targetEntity: Tyre
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
                tyre_id:
                    referencedColumnName: id
            orphanRemoval: false
        vehicle:
            targetEntity: Vehicle
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
                vehicle_id:
                    referencedColumnName: id
            orphanRemoval: false
    oneToMany:
        rating:
            targetEntity: Rating
            cascade: {  }
            mappedBy: vehicleWheelCombination
            inversedBy: null
            orphanRemoval: false
    lifecycleCallbacks: {  }

symfony2中doctrine的.orm.yml文件的实际意义是什么？
