我有兩個實體,聯繫人和全局。學說實體缺少分配的ID
Example\EventBundle\Entity\EventGlobal:
type: entity
table: EventGlobal
fields:
id:
id: true
type: integer
generator:
strategy: AUTO
oneToOne:
EventKontakt:
targetEntity: Example\EventBundle\Entity\EventContact
mappedBy: EventGlobal
cascade: ["persist"]
Example\EventBundle\Entity\EventContact:
type: entity
table: EventContact
fields:
EventGlobal_id:
id: true
type: integer
oneToOne:
EventGlobal:
targetEntity: Example\EventBundle\Entity\EventGlobal
inversedBy: EventContact
joinColumns:
EventGlobal_id:
referencedColumnName: id
nullable: false
他們工作正常。現在我用Symfony構建一個表格
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add(Stuff..)
->add('EventContact', new EventContactType($this->options))
;
}
表單被正確渲染,並且具有一對一的關係。 但是,當我保存我得到一個錯誤。
,我的錯誤是:
Entity of type Example\EventBundle\Entity\EventContact is missing an assigned ID. The identifier generation strategy for this entity requires the ID field to be populated before EntityManager#persist() is called. If you want automatically generated identifiers instead you need to adjust the metadata mapping accordingly.
我怎樣才能achive我後的安全是由Symfony的/學說做了什麼?
它的工作部分,如果我只產生一個eventglobal沒有eventcontact一次,然後返回生成這兩個ID是壞了,並鏈接到最後一個條目。 – Tny 2012-04-06 23:27:15
