*You are storing the image twice:*
*
*
*if trabalhador_form.process(onvalidation=attach_image_to_record).accepted:
# here after validation *
*def attach_image_to_record(form):*
...
photo=db.trabalhador.foto.store(temp,'foto.jpg') # here on validation
* ... *
form.vars.photo=photo *# here is where someting goes wrong....*
*
*
*The problem is that you altering the form on validation.*
*
*
*
*
*This this:*
*
*
**
*def attach_image_to_record(form):*
import cgi
response=requests.get(form.vars.fp_url)
img=Image.open(StringIO(response.content))
img.save('foto1231.jpg','JPEG')
photo = cgi.FieldStorage()
photo.file = open('foto1231.jpg','rb')
photo.filename = 'foto.jpg'
form.vars.photo=photo # not this on, you let process do upload
**
This is very important for me ,
