Deleting Files through a has many association

[ghost]

I setup a hasmany association between products and images. I defined a AttachmentBehavior in the image model. When adding a product the images are uploaded and saved fine. When I delete the record the image record and main image is only removed but not the 2 additional transforms I defined. I can't figure out why only 1 of the 3 images are only removed.

public $actsAs = array(
        'Uploader.Attachment' => array(
                'image' => array(
                    'dbColumn' => 'image_orig',
                    'nameCallback' => 'transformName',
                    'uploadDir' => 'img/product_images/',
                    'finalPath' => 'img/product_images/',
                    'overwrite' => true,                    
                    'transforms' => array(
                                    'max' => array(
                                        'dbColumn' => 'image_max',
                                        'nameCallback' => 'formatName',
                                        'uploadDir' => 'img/product_images/max/',
                                        'finalPath' => 'img/product_images/max/',
                                        'class' => 'resize',
                                        'width' => 800,
                                        'height' => 600,
                                        'aspect' => false
                                    ),
                                    'thumb' => array(
                                        'dbColumn' => 'image_thumb',
                                        'nameCallback' => 'formatName',
                                        'uploadDir' => 'img/product_images/thumb/',
                                        'finalPath' => 'img/product_images/thumb/',
                                        'class' => 'resize',
                                        'width' => 100,
                                        'height' => 100,
                                        'aspect' => false
                        )           )
                )

            )
        );

Are the child records deleted but not the images? Or are the child records still there also?

[ghost]

This is my image table. only the first image gets deleted when deleting the product record associated.

[ghost]

What did you mean by child records, My form in products has one image input. When submitting it is creating 1 record in images any the behavior saves 3 version of the image. When deleting the product record the record in images deletes and the first image but not the 2 additional transforms.

[milesj]

Yeah that's what I meant.

That all looks good. What versions are you using?

[ghost]

cakephp 2.4.3, uploader ver 4.5.0, php 5.5.3. I did email some model/controller clips yesterday for you to look at.

[ghost]

What direction should I research?

[milesj]

Won't have time to look at this until after the holidays, but you can debug a bit. Basically just see if the beforeDelete() is being called for images.

https://github.com/milesj/uploader/blob/master/Model/Behavior/AttachmentBehavior.php#L259

If it's not, it may be a limitation of Cake. If it is being called, make sure that all the fields with files are deleted here.

https://github.com/milesj/uploader/blob/master/Model/Behavior/AttachmentBehavior.php#L443

Did a little debug in attachmentBehavior.php line 470

pr($columns[$column]) ;pr($value);

data returned was good, so we are still holding the data to be deleted.

Array
(
    [image_orig] => image
    [image_max] => image
    [image_thumb] => image
)
image
img/product_images/04f6b3ea183eb9d70981161c4424a6cf525afd9f.png
image
img/product_images/max/04f6b3ea183eb9d70981161c4424a6cf525afd9f.png
image
img/product_images/thumb/04f6b3ea183eb9d70981161c4424a6cf525afd9f.png

the next line is

 if ($this->_deleteFile($model, $columns[$column], $value)) {
$save[$column] = '';

[ghost]

After further testing as long as you don't separate the images into folders all 3 images get deleted correctly. can we add this function?

[milesj]

Figured it out.

You also need to be using absolute URLs for uploadDir.

I went ahead and set the following.

define('UPLOAD_DIR', WWW_ROOT . '/img/product_images/max/');

Then in the model for the transforms

'transforms' => array(
                    'imageMax' => array(
                        'class' => 'resize',
                        'nameCallback' => 'formatName',
                        'append' => '-max',
                        'prepend' => '',
                        'uploadDir' => UPLOAD_DIR,
//                        'finalPath' => 'product_images/',
                        'dbColumn' => 'image_max',
                        'defaultPath' => '',
                        'overwrite' => true,
                        'self' => false,
                        'width' => PRODUCT_MAX_WIDTH,
                        'height' => PRODUCT_MAX_HEIGHT,
                        'aspect' => false

All 3 upload fine. When deleting the record this or still remains.

[milesj]

Have you updated versions? I tested it last night with your exact configuration and it worked.

[ghost]

Will test again, didn't see you updated to 4.5.1
