I have played with doing this several different ways, but to no avail. Currently I have a function:
def qrret(): rows = db().select(db.geo_item.f_name,db.geo_item.f_qrcode, orderby=db. geo_item.f_name) rows2 = db().select(db.geo_collection.f_name, db.geo_collection.f_qrcode , orderby=db.geo_collection.f_name) items=[] colls=[] for row in rows: items += [ OPTION(row.f_name, _value=row.f_qrcode) ] for row in rows2: colls += [ OPTION(row.f_name, _value=row.f_qrcode) ] fields = [DIV(H4("Items"), SELECT(items, _name=items, _multiple=True,_size =10), _class="span6"), DIV(H4("Collections"), SELECT(colls, _name=colls, _multiple=True,_size =10), _class="span6"), BR(), DIV(INPUT(_type='submit'), _style="margin-top: 20px", _class= "span12")] form=FORM(fields, onvalidation=qrparse) return dict(form=form) This function returns the form as I need it in the view. The onvalidation function 'qrparse' is: def qrparse(form): codes = form.vars.items codes += form.vars.colls images = qrmake(codes) return images Which in turn calls: def qrmake(codes): images = [] background = Image.new('RGBA', (1275,1650), (255, 255, 255, 255)) margin = 150 bg_w,bg_h=background.size offset_left = margin offset_down = margin rowend = bg_w - margin pageend = bg_h - margin for i in xrange(len(codes)): code = codes[i] try: img = Image.open(request.folder + 'uploads/' + code) except: continue img.thumbnail((300, 300), Image.ANTIALIAS) img_w,img_h=img.size pasted = False while pasted == False: if offset_left + img_w > rowend: offset_down += img_h offset_left = margin elif offset_down + img_h > pageend: images += background images += qrmake(codes[i:]) return images else: background.paste(img,(offset_left,offset_down)) pasted = True images += background return images What I need to happen though is to display the images that I generated in the validation. I have played with doing this several different ways, but nothing has worked so far. Am I approaching this the wrong way or is there something I am missing? -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
