I have an Image model:
class Image(models.Model):
photo = ImageWithThumbsField(
upload_to=image_upload_location,
sizes=((thumb_widths,thumb_heights),))
The ImageWithThumbsField is something I got from
http://code.google.com/p/django-thumbs/
It seems to work fine when I have a ModelForm created from the Image
model, but at the moment I'm trying to create a Image object, and save
it - so I do this:
new_image = ImageWithThumbsField(images_to_save[image],
upload_to=ListingModels.image_upload_location,
sizes=((ListingModels.thumb_widths,
ListingModels.thumb_heights),))
image_object= Image(photo=new_image)
image_object.save()
The ImageWithThumbsField class extends django.db.models.ImageField,
and sets another class 'ImageWithThumbsFieldFile' as the attr_class.
I'm guessing that the attr_class is used when the Model is saved -as
the ImageWithThumbsFieldFile __init__ method is called when the model
is being saved:
class ImageWithThumbsFieldFile(ImageFieldFile):
"""
See ImageWithThumbsField for usage example
"""
def __init__(self, *args, **kwargs):
super(ImageWithThumbsFieldFile, self).__init__(*args,
**kwargs)
self.sizes = self.field.sizes
if self.sizes:
def get_size(self, size):
if not self:
return ''
else:
split = self.url.rsplit('.',1)
thumb_url = '%s.%sx%s.%s' % (split[0],w,h,split
[1])
return thumb_url
for size in self.sizes:
(w,h) = size
setattr(self, 'url_%sx%s' % (w,h), get_size(self,
size))
The Line that causes the failure is in ImageWithThumbsFieldFile, and
is the split = self.url.rsplit('.',1) line.

I'm really struggling with this error, if anyone has any ideas, I'll
be glad to hear them :)
