Saving webp image near jpg version

[Дмитрий Горобец]

I want to save webp image near jpg version.

Now I'm doing it this way:

class ProductImage(models.Model):

    product = models.ForeignKey(

        to=Product,

        related_name='images',

        on_delete=models.CASCADE,

    )

    image = models.ImageField(

        upload_to=upload_product_image,

        default='',

        blank=True,

        max_length=255,

    )

    def save(self, **kwargs):

        super().save(**kwargs)

        self.create_webp_image()

    def create_webp_image(self):

        image = Image.open(self.image.path)

        path = os.path.splitext(self.image.path)[0] + '.webp'

        image.save(path, 'WEBP')

Is there more elegant way to do it?

Thank you.

Actually, you need to use any background library ( like https://github.com/arteria/django-background-tasks/ ) for processing large-time operations such as image processing.
