def THUMB(image, nx=120, ny=120,
basefolder=os.path.join(request.folder, 'uploads')):

import Image
img = Image.open(os.path.join(basefolder, image))
img.thumbnail((nx,ny), Image.ANTIALIAS)
root, ext = os.path.splitext(image)
thumb ='%s_thumb%s' % (root, ext)
img.save(os.path.join(basefolder, thumb))
return thumb
dbh.define_table(
'table_name',
Field('image', 'upload', uploadfolder=uploadfolder,
autodelete=True),
Field('thumbnail', 'upload', uploadfolder=uploadfolder,
autodelete=True,
compute = lambda r: THUMB(r['image'],
basefolder=uploadfolder)),
)
This is almost copy-paste from one of my apps. Works like a charm.
Note the reference to the slice.
