Dear All,
i am trying to make a Thumb and i used this code here :
Model:
db.define_table('uploads',
Field('name','string'),
Field('mainfile','upload'),
Field('thumb','upload',writable=False,readable=False),
)
Controller:
def makeThumbnail(dbtable,ImageID,size=(150,150)):
try:
thisImage=db(dbtable.id==ImageID).select()[0]
import os, uuid
from PIL import Image
except: return
im=Image.open(request.folder + 'uploads/' + thisImage.mainfile)
im.thumbnail(size,Image.ANTIALIAS)
thumbName='uploads.thumb.%s.jpg' % (uuid.uuid4())
im.save(request.folder + 'uploads/' + thumbName,'jpeg')
thisImage.update_record(thumb=thumbName)
return
def uploadimage():
dbtable = db.uploads #uploads table name
if len(request.args):
records = db(dbtable.id==request.args[0]).select()
if len(request.args) and len(records):
form = SQLFORM(dbtable, records[0], deletable=True)
else:
form = SQLFORM(dbtable)
if form.accepts(request.vars, session):
response.flash = 'form accepted'
makeThumbnail(dbtable,form.vars.id,(175,175))
elif form.errors:
response.flash = 'form has errors'
## Quick list just to demonstrate...
list = crud.select(dbtable)
return dict(form=form,list=list)
But after i upload an image i don't get a thumb i don't know why just
the original image and the thumb Field in the database stays empty , i
don't know why so help me guys ...
Best regards,
