symfony2：无法以一对一关系合并形式插入

Question

客户实体与信用实体具有一对一关系。 当我尝试插入时，出现以下错误：

*

Jobeet \\ JobBundle \\ Entity \\ Credit类型的实体缺少为字段“ id”分配的ID。 该实体的标识符生成策略要求在调用EntityManager＃persist（）之前填充ID字段。 如果要自动生成的标识符，则需要相应地调整元数据映射。

我想念什么？

Customer.orm.yml

type: entity
    table: customer
    id:
        id:
            type: integer
            generator: { strategy: AUTO }
    fields:
        name:
            type: string
            length: 255
            nullable: true
        address:
            type: string
            length: 255

    oneToOne:
        credit:
            targetEntity: Credit
            mappedBy: customer
            cascade: [persist]

信用额度

type: entity
table: credit

        inversedBy: credit
        joinColumn:
            name: customer_id
            referencedColumnName: id

CustomerType.php

class CustomerType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('address')
            ->add('credit', new CreditType())
        ;
    }
}

尝试将Credit.orm.yml更改为

type: entity
    table: credit
    id:
        id:
            type: integer
            unique: true
            column: other_non_conflict_column_name
...
