getting the foreign key in Yii

Question

I have the database like

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

 ======= Member ========
 id
 group_id
 firstname
 secondname
 membersince

Now in my Group Controller file I have used the action update to update the models

public function actionUpdate($id)
  {
    $model=$this->loadModel($id);
    $member = Member::model()->findByPk($_GET['id']);

    if(isset($_POST['Group']))
    {
      $model->attributes=$_POST['Group'];
      if($model->save())
      {
        $member->attributes = $_POST['Member'];
        $member->group_id = $model->id;
        if($member->save())
        {
          $this->redirect(array('view','id'=>$model->id));
        }
      }
      $this->redirect(array('view','id'=>$model->id));
    }

    $this->render('create',array(
      'model'=>$model,
      'member'=>$member,
    ));
  }

Now as I have two model Group and Member , and in group controller file I am saving member attributes. So my problem is when I am using this line $member = Member::model()->findByPk($_GET['id']); for getting the group_id from table member where I can get the complete fields for the group. So can some one tell me how o get the group_id from that table.I searched the documntationbut not got any field like findByFk. So pls guide me.

Answer 1

The relation between is Group and Member is ONE to MANY, so more than one member could exist for a single group id, and your action behavior doesn't look completely correct.

Anyway, the code you are looking for should be the following:

$member = Member::model()->findByAttributes(array('group_id', $_GET['id']));

It is documented here: http://www.yiiframework.com/doc/api/1.1/CActiveRecord#findByAttributes-detail

Answer 2

您可以使用findByAttributes()

$member = Member::model()->findByAttributes(array('group_id'=>$_GET['id']));
