How do you convert a PIL `Image` to a Django `File`?

Question

I\'m trying to convert an UploadedFile to a PIL Image object to thumbnail it, and then convert the PIL Image object that my thumbnail

Answer 1

To complete for those who, like me, want to couple it with Django's FileSystemStorage: (What I do here is upload an image, resize it to 2 dimensions and save both files.

utils.py

def resize_and_save(file):
    size = 1024, 1024
    thumbnail_size = 300, 300
    uploaded_file_url = getURLforFile(file, size, MEDIA_ROOT)
    uploaded_thumbnail_url = getURLforFile(file, thumbnail_size, THUMBNAIL_ROOT)
    return [uploaded_file_url, uploaded_thumbnail_url]

def getURLforFile(file, size, location):
    img = Image.open(file)
    img.thumbnail(size, Image.ANTIALIAS)
    thumb_io = BytesIO()
    img.save(thumb_io, format='JPEG')
    thumb_file = InMemoryUploadedFile(thumb_io, None, file.name, 'image/jpeg', thumb_io.tell, None)
    fs = FileSystemStorage(location=location)
    filename = fs.save(file.name, thumb_file)
    return fs.url(filename)  

In views.py

if request.FILES:
        fl, thumbnail = resize_and_save(request.FILES['avatar'])
        #delete old profile picture before saving new one
        try:
            os.remove(BASE_DIR + user.userprofile.avatarURL)
        except Exception as e:
            pass         
        user.userprofile.avatarURL = fl
        user.userprofile.thumbnailURL = thumbnail
        user.userprofile.save()
