This is a django.core.files.File (or subclass) object. It is file-like
and can be treated as a file.

resized_image is a pil.Image. Again, it is file-like, but it is not a
django.core.files.File...

> _photo.file = resized_image
> _photo.save()

so this doesn't work. You will need to wrap the PIL.Image file-like
object with the django File class (remember appropriate imports):

_photo.file = File(resized_image)
_photo.save()

Sorry - can't help you there. I prefer using pip packages than writing my
own code - where possible. :-)

Re: save cropped image with PIL to database

[Andréas Kühne]

I would have a look at the easy-thumbnails plugin (
http://easy-thumbnails.readthedocs.io/en/2.1/). It uses pillow behind the
scenes and it is very easy to do the cropping and everything that you need
and you don't need to write it yourself :-)

save cropped image with PIL to database

[shahab emami]

hello

i have a question and i cant find answer with search.

i want to save cropped image in database then :
this is my model:

class Photo(models.Model):
file= models.ImageField(upload_to='%Y/%m/%d', blank=True,null=True)


i have a form then user can select image and send to view like this:


{% csrf_token %}

  



  


and in the view i have this :

from PIL import Image


def save_photo(request):

_photo, created = models.Photo.objects.get_or_create(pk=1)

if request.method == 'POST':
photo = request.FILES.get('file')

image = Image.open(photo)

cropped_image = image.crop((100, 100, 200, 200))
resized_image = cropped_image.resize((200, 200), Image.ANTIALIAS)
_photo.file = resized_image
_photo.save()


return HttpResponse("your image has been saved")





but i get this error:

'Image' object has no attribute '_committed'



i'm sure my mistake is in views.py but i dont now how to fix it. how can 
put resized_image that is an object of Image class to 
a model.
can you help me please?
