Question

我有两个表，Clientes和Servicios他们有关系，我希望doctrine只返回客户端的服务而不是我使用addAction表单时存在的所有服务，例如：

`Client: Foo

     Services:
         Bar
         Bar2
         Bar3
Client: Foo2

     Services:
         Bar2
         Bar7
Client: Foo3

     Services:
         Bar`

我不知道如何告诉Symfony2或Doctrine client Foo已分配X服务......

这是教义yml

Pge\IncidenciasBundle\Entity\Clientes:
    type: entity
    table: clientes
    id:
        id:
          type: integer
          unsigned: false
          nullable: false
          generator:
              strategy: IDENTITY
    fields:
        nombre:
            type: string
            length: 250
            fixed: false
            nullable: true
    manyToOne:
        servicio:
            targetEntity: Servicios
            cascade: {  }
            mappedBy: null
            inversedBy: cliente
            joinColumns:
                servicio_id:
                    referencedColumnName: id
            orphanRemoval: false
    oneToMany:
        incidencia:
            targetEntity: Incidencias
            cascade: {  }
            mappedBy: cliente
            inversedBy: null
            orphanRemoval: false
    lifecycleCallbacks: {  }
Pge\IncidenciasBundle\Entity\Servicios:
    type: entity
    table: servicios
    id:
        id:
          type: integer
          unsigned: false
          nullable: false
          generator:
              strategy: IDENTITY
    fields:
        nombre:
            type: string
            length: 250
            fixed: false
            nullable: true
    oneToMany:
        cliente:
            targetEntity: Clientes
            cascade: {  }
            mappedBy: servicio
            inversedBy: null
            orphanRemoval: false
        incidencia:
            targetEntity: Incidencias
            cascade: {  }
            mappedBy: servicio
            inversedBy: null
            orphanRemoval: false
    lifecycleCallbacks: {  }

Doctrine无法确定哪个列应该是您的主键。

将您的ID移到yaml文件中的一个级别：

table: servicios

id:
    id:
        type: integer
        unsigned: false
        nullable: false
        generator:
            strategy: IDENTITY
fields:

然后运行app / console doctrine：schema：create --dump-sql

看看你得到了什么。可能还有其他错误。我看起来并不真实。如有必要，从剥离的yaml文件开始，然后一次添加一个字段。我怀疑你想要无符号也是如此。
