Php 外键未存储在Yii中

我有一个像这样的adatabase

====Group=====
id
name

====Member====
id
group_id
firstname
lastname
membersince


Now as group_id is foreign key then when I will save Group tabale then the group_id should be save with that number.
In relations I have made relations for Group is



     public function relations()
  {
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
      'member' => array(self::HAS_MANY, 'Member', 'groupid'),
    );
  }

 public function relations()
  {
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
      'group' => array(self::BELONGS_TO,'Group','groupid'),
    );
      }

在成员模型中，我的关系就是这样

====Group=====
id
name

====Member====
id
group_id
firstname
lastname
membersince


Now as group_id is foreign key then when I will save Group tabale then the group_id should be save with that number.
In relations I have made relations for Group is



     public function relations()
  {
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
      'member' => array(self::HAS_MANY, 'Member', 'groupid'),
    );
  }

 public function relations()
  {
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
      'group' => array(self::BELONGS_TO,'Group','groupid'),
    );
      }

现在，我将以单一形式保存这两个模型（示例如下），这两个模型已成功保存，但未存储外键。因此，有人能告诉我哪里出了问题吗

我需要查看您的控制器I已更新控制器的代码..因此请帮助我我看不到您正在保存2条记录的位置。。。此外，如果能看到表单，那就太好了。你还需要一些帮助吗？如果是，您是否正在尝试为成员模型设置组id，并且出现问题？我最近才这么做，所以可以发布一些示例代码…我遇到了完全相同的问题，您找到了解决方案吗？我使用的是
$form->activeDropDownList（$model，'position\u type\u id'，CHtml:：listData（PositionType:：model（）->findAll（），'id'，'name'）
生成我的下拉列表，尽管它正确填充，但它不会保存传递回控制器的值。我可以打印出POST变量中的值，并且它的名称正确。
