I’m on Django==5.2.12 and django-imagekit==6.1.0

This is my PostImage model:

```auto
class PostImage(models.Model):
    post = models.ForeignKey(Post, on_delete=models.CASCADE, null=True, related_name="images")
    image = ProcessedImageField(verbose_name=_("image"), storage=post_image_storage, upload_to=upload_to_post_image_directory, width_field="width", height_field="height", blank=False, null=True, format="JPEG", options={"quality": 100}, processors=[ResizeToFit(width=1024, upscale=False)])
    width = models.PositiveIntegerField(editable=False, null=False, blank=False)
    height = models.PositiveIntegerField(editable=False, null=False, blank=False)
    hash = models.CharField(_("hash"), max_length=64, blank=False, null=True)
    thumbnail = ProcessedImageField(verbose_name=_("thumbnail"), storage=post_image_storage, upload_to=upload_to_post_image_directory, blank=False, null=True, format="JPEG", options={"quality": 50}, processors=[ResizeToFit(width=1024, upscale=False)])
    media = GenericRelation(PostMedia)
    image_view_type = (
        ("regularimage", "regularimage"),
        ("gridimages", "gridimages"),
    viewtype = models.CharField(max_length=24, choices=image_view_type, default="")

```

While create a PostImage object, I get thrown the error.

> null value in column “width” violates not null constraint.

Since I require the width and height fields to be calculated for further processing,

I don’t want to change the fields width and height with null=True. However, just to check what happens after doing it, i did try specifying null=True. The PostImage object does get created but with no values for width and height.

Detailed trace:

```auto

 django.db.utils.IntegrityError: null value in column "width" of relation "myapi_posts_postimage" violates not-null constraint
my-api-webserver-0 | DETAIL: Failing row contains (1, posts/9957dc49-639b-490e-87f5-54cab35c0229/582a8f62-86d5-4c3d-a1..., null, null, 01d2d1ce86aa7007f1cecad2259394163b95987a850e6c2d6a48c322a2dc8df0, posts/9957dc49-639b-490e-87f5-54cab35c0229/33d944aa-ded1-49cb-a9..., regularimage, 1).

```

Haven’t been able to get a response on stack overflow yet. This is driving me nuts.

Hi @narayanan-ka, can you please share a bit more of context, in example:

- how are you saving your model?
- if you use a form, the form declaration/configuration?

I suspect that the issue is that currently nothing is setting your `width` attribute on your model, but without more elements I cannot be sure.

Also keep in mind that this configuration is dangerous: the `image` field is nullable, yet `height` and `width` are not-nullable without any default. If an image is not provided you are going to have an `IntegrityError` because the field cannot calculate those attributes without an image!

Hi. Working fine with Django 5.0.14. Here is the discussion on django-imagekit.

Good to hear that it works with a previous version of django, however to better identify the problem I need to see how are you saving your model instance.

You are just posting your model setup and the last frame of error stack: to figure out the real problem **at least** the full stack-trace is required. There are too many context info missing here.
