New description:
My model:
{{{
class MyModel(models.Model):
picture = models.ImageField(blank=True, null=True,
upload_to='pictures')
}}}
Update a single object:
{{{
>>> picture
>>> <ContentFile: Raw content>
>>> mymodel = MyModel.objects.get(pk=instance.pk)
>>> mymodel.picture = picture
>>> mymodel.save()
>>> mymodel.picture
>>> <ImageFieldFile: pictures/fbdfe25b-b246-4f2d-9436-dca49aef88d7.png>
}}}
Good. Url result
`/media/pictures/fbdfe25b-b246-4f2d-9436-dca49aef88d7.png`.
Update a single object with the `update()` method:
{{{
>>> picture
>>> <ContentFile: Raw content>
>>> MyModel.objects.filter(pk=instance.pk).update(picture=picture)
>>> mymodel = MyModel.objects.get(pk=instance.pk)
>>> mymodel.picture
>>> <ImageFieldFile: Raw content>
}}}
Bad. Url result: `/media/Raw%20content`.
