Django loading image from url - ImageField objected has no attribute _committed

I am using Django 3.2

I am trying to programatically create a model Foo that contains an ImageField object, when passed an image URL.

This is my code:

myproject/models.py

class ImageModel(models.Model):
    image = models.ImageField(_('image'),
                              max_length=IMAGE_FIELD_MAX_LENGTH,
                              upload_to=get_storage_path)
    # ...

class Foo(ImageModel):
    # ...

code attempting to create a Foo object from a passed in photo URL

# ...

image_content = ContentFile(requests.get(photo_url).content) # NOQA                          
image = ImageField() # empty image

data_dict = {
                'image': image,
                'date_taken': payload['date_taken'],
                'title': payload['title'],
                'caption': payload['caption'],
                'date_added': payload['date_added'],
                'is_public': False  
            }

foo = Foo.objects.create(**data_dict) # <- Barfs here
foo.image.save(str(uuid4()), image_content)
foo.save()  # <- not sure if this save is necessary ...

When the code snippet above is run, I get the following error:

ImageField object does attribute _committed

I know this question has been asked several times already - however, none of the accepted answers (from which my code is based) - actually works. I'm not sure if this is because the answers are old.

My question therefore is this - how do I fix this error, so that I can load an image from a URL and dynamically create an object that has an ImageField - using the fetched image?
