afterDelete not working when deleting from belongsTo

[emilushi]

So... I do have a model called Notes and another model called Attachments. The Attachments model belongsTo Notes and Notes hasMany Attachment.

With some modifications I was able to make it possible to add multiple Attachments at the same time from NotesController when creating a new Note. And what is expected to happen when you delete a Note is: Delete note, Delete all attachments related to that Note and as well delete all files uploaded for those attachments.

The files are never deleted.

What I ended up doing is: Removed webroot for file dir with beforeSave as below:

public function beforeSave(Event $event, Entity $entity, ArrayObject $options): void
{
    $dir = str_replace('webroot/', '', $entity->get('dir'));
    $entity->set('dir', $dir);
}

On this way the dir of the file will not contain weebroot in my case it will be: files/Attachments/attachment This as well helped me echoing the file url with: $this->Url->build($file->dir.$file->name)

And for deleting I needed to add an afterDelete as below:

public function afterDelete(Event $event, Entity $entity, ArrayObject $options): void
{
    $file = new File($entity->get('dir').$entity->get('name'));
    $file->delete();
}

Have you enabled cascading callbacks for your associations? Without that the ORM will use deleteAll() to delete the associated records and hence afterDelete callbacks won't be triggered for them.

I have enabled of course.

As well I had some issues when adding a record for Notes table with multi attachments.

This didn't work for me:

if ($this->request->is('post')) {
    $note = $this-Notes->newEntity($this->getRequest()->getData(), [
        'associated' => ['Attachments']
    ])

    $this-Notes->save($note);
}

attachments doesn't show at all when I debug the Notes entity, and of course if I debug $this-getRequest()->getData() the attachments items are there.

Instead I had to:

$note = $this->Notes->newEntity();
if ($this->request->is('post')) {

    $files = $this->getRequest()->getData('attachments') ?? [];

    $note = $this-Notes->patchEntity($note, $this->getRequest()->getData())

    if($this-Notes->save($note)) {

        array_walk($files, function ($item, $key) use (&$files, $note) {

             if (is_array($item)) {
                 $files[$key]['foreign_key'] = $note->id;
             }

             return $files;
        });

        $attachmentsTable = TableRegistry::getTableLocator()->get('Attachments');
        $attachments      = $attachmentsTable->newEntities($files);
        $attachmentsTable->saveMany($attachments);

    }

}

Only on this way I was able to make the relationship work.

Have you set the attachments property accessible in the entity?

I feel so dumb right now. I generated the code with bake and the attachments was added later 😞
