Need Help :(

mastah2 ane mau tanya niih

ane mau ngisi secara otomatis tabel header am confirmation

di controller ane penampakannya gini

public function actionCreate()

	{

		public function actionCreate()

	{

		$model=new LksaData;


		// Uncomment the following line if AJAX validation is needed

		// $this->performAjaxValidation($model);


		if(isset($_POST['LksaData']))

		{

			$model->attributes=$_POST['LksaData'];

			$model->picture = CUploadedFile::getInstance($model,'picture');

			$regency=  Regency::model()->findByAttributes(array('regency_name' => $model->regency_id));

			$model->regency_id=$regency->id;

			$model->year =date('Y-n-j');


			$path_product = Yii::app()->getBasePath().'/../images/accountPicture/';

			if($model->save()){

//				var_dump($model->lksa_code);

//				die();

				$model->picture->saveAs($path_product . $model->picture->name);

				}

//isi tabel lksa header

			$lksaDataHeader = new LksaDataHeader;

			

			$lksaDataHeader->registration_number="LKSA".$model->regency->province->province_code.".".$model->regency->regency_code.".".$model->lksa_code.".".$this->randomStringBook();

			$lksaDataHeader->lksa_data_id=$model->id;

			$lksaDataHeader->register_date =date('Y-n-j');

			$lksaDataHeader->save();

//isi tabel detail confirmation

$documentLksaDataConfirmation = new DocumentLksaDataConfirmation;

$documentLksaDataConfirmation->lksa_data_header_id=$lksaDataHeader->id;

$documentLksaDataConfirmation->save();

			

			

			$this->redirect(array('lksadataheader/view','id'=>$lksaDataHeader->id));

		}


		$this->render('create',array(

			'model'=>$model,

		));

	}

jalan dan pas di var_dump semuanya ada isinya nah pertanyaannya adalah,kok pas create yg DocumentLksaDataConfirmation g ke create,kenapa ya?apa karena controller create nya g punya relation ama DocumentLksaDataConfirmation(relationnya datalksa->header->baru documentdata) makanya begitu?

kira2 klo ane mau ambil id lksaDataHeader buat ditaro di tabel documentlksa gimana ya?
