General one-to-one relationship in Django

Question

I have an image model:

class Image(models.Model):
    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField()
    content_object = generic.GenericForeignKey()
    image = models.ImageField()

I also have a model that has fields

class MyModel(models.Model):
    logo = models.ImageField()
    icon = models.ImageField()
    images = generic.GenericRelation(Image)

I want logou to iconalso use a common attitude Image. How can i do this?

In many models, I use a common model Image, so it should be a general relation. I just want to use the same model for all images, even if they are icons, profile images, or something else.

It would be best if Django had a field generic.GenericOneToOneRelation(Image)or something :-)

The only solution I can think of is

class MyModel(models.Model):
    logo = models.ForeignKey(Image)
    icon = models.ForeignKey(Image)
    images = generic.GenericRelation(Image)

logo icon images logo icon images, images, . ?
