Delete file on changing file

[Mte90]

In my model I have a code that delete the original file when is changed to not have multiple useless files around. The problem it is to do the same for the thumbnails generated.

@deconstructible
class PathAndRename:
    """
    A callable class that generates unique file paths for uploads.

    This class is designed to be used as the upload_to parameter in Django model fields.
    It generates a unique filename using UUID4 while preserving the original file extension,
    and places the file in the specified subdirectory.

    The @deconstructible decorator makes this class serializable for Django migrations,
    which is essential for avoiding migration generation issues.

    Note: No slash for the path!

    Args:
        sub_path (str): The subdirectory path where files should be stored

    Example:
        >>> uploader = PathAndRename("product_logos")
        >>> uploader(instance, "logo.png")
        'product_logos/abc123def456.png'
    """

    def __init__(self, sub_path):
        self.path = sub_path

    def __call__(self, instance, filename):
        ext = filename.split(".")[-1]
        filename = f"{uuid4().hex}.{ext}"
        return os.path.join(self.path, filename)

    path_and_rename = PathAndRename("product_logos")
    logo = VersatileImageField(
        upload_to=path_and_rename,
    )
