Question

这是我的问题：我想创建一个“资源”的新实例，并直接创建与该资源相关的'ResourceDescriptions'实例，并将1：n关系转换为一种形式。

一些背景信息：

1）简化架构

ResourceDescriptions:
    connection: doctrine
    tableName: resource_descriptions
    columns:
    id:
      type: integer(4)
      fixed: false
      unsigned: true
      primary: true
      autoincrement: false
    description:
      type: string()
      fixed: false
      unsigned: false
      primary: false
      notnull: true
      autoincrement: false
    relations:
    Resources:
      local: id
      foreign: id
      type: one
Resources:
    connection: doctrine
    tableName: resources
    columns:
    id:
      type: integer(4)
      fixed: false
      unsigned: true
      primary: true
      autoincrement: false
    relations:
        ResourceDescriptions:
          local: id
          foreign: id
          type: many

2）ResourcesForm

if ($this->getObject()->isNew()){
    $newDescription = new ResourceDescriptions();
    $newDescription->setResources($this->getObject());
    $newDescription->setId($this->getObject()->getId());
    $newDescriptionForm = new ResourceDescriptionsForm($newDescription);
    $this->embedForm('Description', $newDescriptionForm);
}
$this->embedRelation('ResourceDescriptions');

3）ResourceDescriptionsForm

public function configure(){

    $this->useFields(array('id', 'description'));

    $this->setWidgets(array('id' => new sfWidgetFormInputHidden(array('default' => $this->getObject()->getId())), 'description' => new sfWidgetFormTextarea(),'expanded' => true,'multiple' => true),array('class' => 'checkbox'))));

    $this->setValidators(array('id' => new sfValidatorPass, 'description' => new sfValidatorString(array('max_length' => 250)), 'multiple' => true))));

}

这里的问题是我想得到一个'资源'对象的id还没有被放入数据库...有没有办法在插入之前得到它或另一种方法是能够同时（或多或少）创建描述作为资源吗？
