Téléchargement d'une image via Admin dans Django

Question

J'essaye de télécharger une image via le panneau d'administration de Django. Je cours sur Google App Engine et j'utilise le plugin filetransfers (je ne sais pas si l'un ou l'autre est pertinent par rapport au problème que j'ai).

De mon modelys.py:

from django.db import models 

# Create your models here. 
class CarouselItem (models.Model): 
    caption = models.CharField(max_length=200,blank=True) 
    order = models.IntegerField() 
    carousel_image = models.ImageField(upload_to='uploads/carousel_image/%Y/%m/%d/') 
    def __unicode__(self): 
     return self.caption 

De admin.py:

from carousel.models import CarouselItem 
from django.contrib import admin 
from imperavi.admin import ImperaviAdmin 

class carouselAdmin(ImperaviAdmin): 
    list_display = ('caption','order') 

admin.site.register(CarouselItem, carouselAdmin) 

L'erreur que je reçois est "Aucun module appelé Image". Je n'ai pas installé PIL. Ai-je besoin de l'installer pour activer cette fonctionnalité?

Mise à jour: voici retraçage qui a provoqué l'erreur:

Answer 1

Oui, vous devez installer Pil. Mais avant que vous devez installer sur votre serveur jpeglib (sans que cette PIL ne peut pas fonctionner avec des fichiers jpeg)

Alterall, vous pouvez inclure

from django.db.models import ImageField 

dans votre models.py

Answer 2

Vous avez besoin installer PIL ou équivalent. Oreiller en cas de python 3.x. Si vous avez du mal à l'installer, dites-le, j'en ai et il est facile de corriger, il suffit d'ajouter le chemin de votre python.h. Peut-être cela est fixé maintenant ... Rien à ajouter dans models.py
