我有项目模型

class Project(models.Model):
    id = models.UUIDField(primary_key=True, unique=True, default=uuid4, editable=False)
    logo = models.ImageField(validators=[validate_image_size], blank=True, null=True, default=None)
    name = models.CharField(max_length=64)
    description = models.TextField()

    @transaction.atomic
    def save(self, *args, **kwargs):
        super().save(*args, **kwargs)

    def __str__(self):
        return self.name

我想压缩徽标字段与接收器

@receiver(post_save, sender=Project)
def compress_project_logo(sender, instance, **kwargs):
    compress_image.apply_async((instance.id,))

使用共享任务

@shared_task
def compress_image(project_id):
    from api.models import Project
    project = get_object_or_404(Project, id=project_id)
    compressed_image = Image.open(project.logo)
    compressed_image = compressed_image.convert("RGB")
    compressed_image = ImageOps.exif_transpose(compressed_image)

    image_io = BytesIO()
    compressed_image.save(image_io, "JPEG", quality=70)
    project.logo = InMemoryUploadedFile(image_io, "ImageField", project.logo.file.name, "image/jpeg", sys.getsizeof(image_io), None)
    project.save()

当我通过django管理员保存项目模型时，我把这个
