Strange Issue With Afterdelete()

Yii 1.1 General Discussion
1

Hi,

I’m noob in Yii and trying to learn it. Following Building a Blog System using Yii and made some customizations. Got some strange issues with afterDelete(). In summary, there some actions which perfectly works using afterSave(), but not working with afterDelete().

  1. Made model and CRUD ‘category’ with relation to post model HAS_MANY. I want to set all posts category_id to 0 when category is deleted, so implementation in category model:



         //doesn't work 

	 protected function afterDelete()

	{

  		parent::afterDelete();

		Post::model()->updateAll(array('category_id'=>0), ('category_id='.$this->id));

	}

but…




        //works perfectly

	protected function afterSave()

	{

    	parent::afterSave();

    	//Post::model()->updateAll(array('category_id'=>0), ('category_id='.$this->id));

    	Post::model()->updateAll(array('category_id'=>0), ('category_id=4'));


    }
  1. Same issue with given blog tutorial

In Post model:





	protected function afterDelete()

	{

  		parent::afterDelete();

               //works

   		Comment::model()->deleteAll('post_id='.$this->id);

               //doesn't work

    	       Tag::model()->updateFrequency($this->tags, '');

	}

but…





             //works flawlessly

            protected function afterSave()

	   {

    	parent::afterSave();

    	//Tag::model()->updateFrequency($this->_oldTags, $this->tags);

      //deletes or decreases tag freaquency

    	Tag::model()->updateFrequency('someTag', '');

	}

Please, give me some guidence. :rolleyes:

afterDelete is not fired in some cases. Plz show the code that is used for model deletion.

Ok, here is category controller:




public function actionDelete($id)

	{

		$this->loadModel($id)->delete();

		if(!isset($_GET['ajax']))

			$this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array('admin'));

	}


public function loadModel($id)

	{

		$model=Category::model()->findByPk($id);

		if($model===null)

			throw new CHttpException(404,'The requested page does not exist.');

		return $model;

	}

and post controller:




public function actionDelete($id)

	{   //delete only via POST request

		if(Yii::app()->request->isPostRequest)

		{

			$this->loadModel($id)->delete();

		if(!isset($_GET['ajax']))

			$this->redirect(array('index'));

		}

	

		else 

			throw new CHttpException(400,'Invalid request. Please do not repeat this request again.');

		}


private $_model;

	 

	public function loadModel($id)

	{	// if model not loaded yet

		if($this->_model===null)

		{

		//and is given post id

		//somebody tries to access post in url

       	 if(isset($_GET['id']))

		 {

		 	// load model depending on role

		 	// if user is guest

		 	// give him only published or archived posts not drafts

			if(Yii::app()->user->isGuest)

                $condition='status='.Post::STATUS_PUBLISHED

                    .' OR status='.Post::STATUS_ARCHIVED;

            else

            // user is owner - give him all posts

                $condition='';

            // find posts for guest or owner

            $this->_model=Post::model()->findByPk($_GET['id'], $condition);

        }

        //not found any posts matched that condition

        if($this->_model===null)

            throw new CHttpException(404,'The requested page does not exist.');

    }

    //give them posts

    return $this->_model;

}

I am not sure if this could be a problem I tried to reproduce it I setup a new project but it works fine try the following and see if that works


protected function afterDelete()

{

     parent::afterDelete();

     Post::model()->updateAll(array('category_id'=>0), "category_id='{$this->id}'");

}
