Hi Anthony,
Thanks for your continuous help. I tried like below, i had to specify
uploadfolder in SQLFORM.factory(), otherwise web2py raised error saying
user must specify uploadfolder. Then I thought i could override it after
form.accepted, but it didn't. The uploaded file ended up storing under the
top-level folder (auth.user.id) instead of (company_id). One thing I don't
want is to ask the user to fill in company details in 1 form, submit it,
then redirect to another form and upload the logo image. I wonder if you
actually meant what I did below. Thanks!
form=SQLFORM.factory(
Field('company_name', requires=[IS_NOT_EMPTY(),
IS_NOT_IN_DB(db, 'company.company_name')]),
Field('logo', 'upload',
uploadfolder=os.path.join(request.folder, 'uploads', str(auth.user.id)),
uploadseparate=True, autodelete=True), # 23x23mm, 300K recommended
table_name='company',
formstyle='table3cols').process()
if form.accepted:
company_id= db.company.insert(company_name=form.vars.company_name)
db.company.logo.uploadfolder=os.path.join(request.folder,
'uploads', str(company_id)) # 23x23mm, 300K recommended
db.company.chop.uploadseparate=True
db.company.logo.autodelete=True
company_row = db.company(company_id)
company_row.update_record(logo=form.vars.logo)
elif form.errors: ...
else: ...
