Resize image on save (django admin)

[nsash]

Hello,

I am trying to resize image on save from the admin part of django.

My Model is:

class Artwork(models.Model):
file = models.ImageField(upload_to=UPLOAD_DIR,)
title = models.CharField(max_length=100)

def __unicode__(self):
return self.title


def save(self, size=(80, 80)):
super(Artwork, self).save()
if self.file:
filename = self.file
image = Image.open(filename)

image.thumbnail(size, Image.ANTIALIAS)
image.save(filename)


the problem is that I get the error message

'ImageFieldFile' object has no attribute '_mode'.

When I change
filename = self.file
to
filename = '/path/to/some/image/in/the/filesystem/
image.jpg' (hardcoded)
the image is resized without problems.

I think the problem is that I try to open an image that is not yet
stored in the UPLOAD_DIR, but that is only an assumption.

What django version are you using? Try to change the line "filename =
self.file" to "filename = self.file.path"... The way files are treated
on django changed recently, search for the backward incompatibility
changes to know more.

Best regards!
