Thank you. I have just writed this code.
It works but I want to avoit to save 2 times with "super(book,
self).save()" ( see below ):
from django.db import models
from PIL import Image
import glob, os
thumb_size = 90, 90
class book(models.Model):
title = models.CharField(max_length=200)
photo = models.ImageField(upload_to='photo_book')
thumb = models.ImageField(upload_to='thumb_book', blank=True,
null=True)
def save(self):
super(book, self).save()
file_path = self.photo.url
if (file_path):
im = Image.open(file_path)
im.thumbnail(thumb_size, Image.ANTIALIAS)
root, immagin = os.path.split(file_path)
immagin, ext = os.path.splitext(immagin)
im.save("thumb_book/" + immagin + ".thumbnail.jpg",
"JPEG")
self.thumb = "thumb_book/" + immagin + ".thumbnail.jpg"
super(book, self).save()
