First attempt with Wep2py, going through the book, on chapter 7 and stuck
getting both the linkto object to display and have the image filename
stored in the database. I can one or the other but not both. Seems they are
mutally exclusive, although my 2 AI helpers say no. Couldn't find any
conversations here about this. Any help would be greatly appreciated. How
can I get both to work?
Seems that if person.image.filename is allowed to be displayed in the view,
then linking to the image (pressing the button) does not store the filename
in the DB. Is this as designed?
def forms():
record = db.person(request.args(0))
url = URL('download')
link = URL('list_records', args='db')
form = SQLFORM(db.person, record, deletable=True, upload=url,
*linkto*=link, labels = {'dog.owner':"This person's
dogs"},
*fields*=['name', 'gender', 'married', 'profile',
'image'])
if request.vars.image != None:
form.vars.image_filename = request.vars.image.filename
if form.process().accepted:
response.flash = 'form accepted'
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
In general, I'm mystified with what and how things get passed back and
forth between the controllers and the views. Probably due to my lack of
webdev experience, ack. I'd be glad of any other learning resources.
