Yii сохраняет запись из формы 3 раза

У меня есть следующие действия в моем контроллере:

public function actionEntersales()
{
$model = new Sales();
if (!isset($_POST['Sales'])) {
$model->receipt_date = date("Y-m-d", time());
}
if (isset($_POST['Sales'])) {
$model->attributes = $_POST['Sales'];
if ($model->validate()):
$model->save();
$this->redirect(array('company/comissionmanagement'));
endif;
}

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

Он должен проверить и затем сохранить данные формы, где «sales_items» должен быть сохранен один за другим в другой таблице.

Я попытался достичь этой цели, используя foreach по «функциям».

Это связанная модель:

<?php

/**
* This is the model class for table "sales".
*
* The followings are the available columns in table 'sales':
* @property integer $id
* @property integer $company_id
* @property integer $user_id
* @property integer $store_id
* @property integer $receipt_no
* @property string $receipt_date
* @property integer $carrier_id
* @property integer $activationtype_id
* @property string $mdn
* @property string $accountpin
* @property integer $rateplans_id
* @property integer $status3_id
* @property string $created
* @property string $modified
*
* The followings are the available model relations:
* @property Activationtypes $activationtype
* @property Companies $company
* @property Rateplans $rateplans
* @property Stores $store
* @property Users $user
* @property Carriers $carrier
* @property SalesItems[] $salesItems
*/
class Sales extends CActiveRecord
{
/**

*/

public $features;

public function tableName()
{
return 'sales';
}

/**

);
}

/**

public function search()
{

$criteria->compare('id', $this->id);

return new CActiveDataProvider($this, array(

}

public static function model($className = __CLASS__)
{
return parent::model($className);
}

public function beforeValidate()
{
$this->company_id = Yii::app()->user->cid;
$this->status3_id = 0;
return parent::beforeValidate();
}

public function afterSave()
{
if (count($this->features) > 0):
$sid = $this->id;
foreach ($this->features as $key => $fid):
$si = new SalesItems();
$si->sales_id = $sid;
$si->feature_id = $fid;
$si->status2_id = 0;
$si->save(false);
endforeach;
endif;
return parent::afterSave();
}
}

Когда я отправляю форму, она сохраняет запись 3 раза, включая все записи sales_items 3 раза.

Я не вижу в своем коде, почему он так себя ведет.
