sorun burada geçerli:

    thumbnail2 = models.ImageField(upload_to="images/", blank=True, null=True) 

def save(self, *args, **kwargs): 
    """Save image dimensions.""" 
    super(Image, self).save(*args, **kwargs) 
    im = PImage.open(pjoin(MEDIA_ROOT, self.image.name)) 
    self.width, self.height = im.size 

    # large thumbnail 
    fn, ext = os.path.splitext(self.image.name) 
    im.thumbnail((128,128), PImage.ANTIALIAS) 
    thumb_fn = fn + "-thumb2" + ext 
    tf2 = NamedTemporaryFile() 
    im.save(tf2.name, "JPEG") 
    self.thumbnail2.save(thumb_fn, File(open(tf2.name)), save=False) 
    tf2.close() 

    # small thumbnail 
    im.thumbnail((40,40), PImage.ANTIALIAS) 
    thumb_fn = fn + "-thumb" + ext 
    tf = NamedTemporaryFile() 
    im.save(tf.name, "JPEG") 
    self.thumbnail.save(thumb_fn, File(open(tf.name)), save=False) 
    tf.close() 

    super(Image, self).save(*args, ** kwargs) 

Nasıl bu hatayı düzeltebilirim?

Answer 1

Django, MEDIA_ROOT klasörüne erişmek için ihtiyaç duyduğu izinlere sahip değil gibi görünüyor.

Ayarlarınızdaki MEDIA_ROOT ayarlarına bir göz atın. Sonra klasördeki izinleri kontrol edin (bir bash kabuğundan ls -lsa /path/to/media_root gibi). Django çalıştıran kullanıcının klasöre yazma izni olduğundan emin olun. Ayrıca, asermax'ın işaret ettiği gibi, MEDIA_ROOT'unuz içinde bir resim dizini oluşturduğunuzdan emin olun.

Belki de this issue var serving other directories

GÜNCELLEME serving static files özellikle bölüm belgelerine bakın. http://wiki.apache.org/httpd/13PermissionDenied Buna bir göz atın im.save(tf2, "JPEG")

Answer 2

seti SELinux'un permisions ile im.save(tf2.name, "JPEG") yerine deneyin, bu
