Hmm, I don't see how automatic retrieval ever would have worked in the past
if that's the code you use to store the thumbnails.
Anyway, instead of storing the image manually, you should let web2py handle
it:
import cStringIO
thumb = cStringIO.StringIO()
im.save(thumb, format='JPEG') # Save the PIL image to the StringIO object.
thisImage.update_record(thumbnail=dbtable.thumbnail.store(thumb, thumbName))
If you want to stick with your custom storage, then you should create a
custom_retrieve function for the "thumbnail" field to override the default
retrieve method of the field:
def retrieve_thumb(name, path):
[get the file]
return (filename, stream)
db.define_table('mytable',
...
Field('thumbnail', 'upload', custom_retrieve=retrieve_thumb))
