Hi,
I've had the same issue before and did it that way:
Since your object is to upload a file and make a thumbnail at the same
time, then:
1. Hide thumbnail field in a form. User will add image only and web2py
do the rest. In your controller:
fields=['Name','MainPic']
form=SQLFORM(db.yourtable, fields=fields)
2. Create function to make thumbnail and save it into database. This
function will be called just after the form will be accepted. In your
controller:
def makeThumbnail(ImageID):
try: thisImage=db(db.yourtable.id==ImageID).select()[0]
except: return
im=Image.open(request.folder + 'uploads/' + thisImage.MainPic)
im.thumbnail((200,150),Image.ANTIALIAS)
thumbName='Images.ThumbPic.%s.jpg' % (uuid.uuid4())
im.save(request.folder + 'uploads/' + thumbName,'jpeg')
thisImage.update_record(Thumbnail=thumbName)
return
3. Call this function. In your controller:
fields=['Name','MainPic']
form=SQLFORM(db.yourtable, fields=fields)
if form.accepts(request.vars, session):
#form.vars.id is a id field of new record just created
makeThumbnail(form.vars.id)
4. Do not forget to import correct modules in your controller:
from PIL import Image
import uuid
This works for me,
regards,
Lukasz
