[web2py] Re: web2py Issues
Hello Kevin ,
Thanks a lot for your reply.
what i want to do is :
def items():
wo = db(db.WO.id == request.vars.wo_id).select()[0]
checkList_items = db(db.checklist_item.cl_id ==
request.vars.cl_id).select(orderby=checklist_item.id DESC)
form = SQLFORM(SQLDB(None).define_table('myform',
db.WO.project_title,
db.WO.project_manager
),submit_button=T(save))
form.vars.project_title = wo.project_title
form.vars.project_manager = wo.project_manager
count = 4
for item in checkList_items:
form[0].insert(count,TR(TD(item.id),TD(item.item),TD(INPUT(_type='radio',_value=NA
,
_name=item.id
,_class=answer_class,_id=answer_options+str(item.id)),_colspan=1),TD(INPUT(_type='radio',_value='YES'
,
_name=item.id
,_class=answer_class,_id=answer_options)),TD(INPUT(_type='radio',_value='NO'
,
_name=item.id
,_class=answer_class,_id=answer_options),TD(INPUT(_type='text',_id='comment',_name=comment+str(item.id))
if form.accepts(request.vars, session):
for item in checkList_items:
try:
if request.vars[str(item.id)]:
if request.vars[str(item.id)] == NO and
request.vars[comment+str(item.id)] == :
session.flash = Error
#return dict(form=request.vars)
form.vars = request.vars
#redirect(URL(r=request,f='items',vars=request.vars)) ## Here
redirected to empty from How can i fix this
return dict(form=form)
else:
db.answers.insert(field_clI_id=request.vars.fCL_id,clI_id=item.id,answer=request.vars[str(item.id)],comment=request.vars[comment+str(item.id)])
redirect(URL(r=request,f='view'))
except KeyError:
print Error KeyValue
db.answers.insert(field_clI_id=request.vars.fCL_id,clI_id=item.id,answer='None')
redirect(URL(r=request,f='view'))
return dict(form=form)

Hi Neveen,
Without a bit more context I'm having trouble determining the problem. In
principle you should be able to pass vars=request.vars to URL and have them
show up in the redirected URL. For example:
def func1():
if request.vars.value == hello:
return you submitted hello
else:
redirect(URL('func2', vars=request.vars))
def func2():
return BEAUTIFY(request.vars)
If you go to /app/controller/func1?name=Bob you will be redirected
to /app/controller/func1?name=Bob, and request.vars will include a
.name='Bob' attribute.
If you go to /app/controller/func2?name=Bobvalue=hello you'll stay at
func1 and see you submitted hello.
Try starting with that example, verifying that it works for you, and then
extending it to do what you need.
If you could describe a little more about what you are trying to do, and/or
include a bit more of the code you're working with, I might be able to
provide more help. There may be a better way to do this already built in to
web2py.
Cheers,
Kevin

Hello DenesL,
Thanks for your reply.
For Issue#2:
inside get_CIs function the request.vars.WO_cpp_id is None which
represent the selected id from first dropdown.
could you please advice me what the problem?

Hello,
Issue#1:
I want make server validation, but when return the page again i want
to be had the entered values:
e.x:
if request.vars[str(item.id)] == NO and
request.vars[comment+str(item.id)] == :
session.flash = Invalid Value
redirect(URL(r=request,f='items',vars=request.vars))
Hard to tell without the action code but assuming that you are using
form.accepts you should not redirect on form errors.
// The previous code return an empty values.
Issue#2:
Is there a problem in function ajax() with version 1.91.6 .
because when i used
ajax('get_CIs', ['WO_cpp_id'], 'WO_ci_id');
The function get_CIs has been called fine but the
request.vars.WO_cpp_id is None.
Probably the action is returning an empty selection.
Please, How i can fix the previous two issues?
Thanks in Advance
[web2py] Re: web2py Issues
This is hard to follow. Can you isolate the parts that don't work? Are you able to radically simplify the logic?
[web2py] Re: web2py Issues
Why do you need to redirect back to the same view to display the error? The normal way of doing this is basically what you currently have: if there is an error in the form in the POST, immediately redisplay the form. I think the reason this is failing is because of the formkey technique used by web2py. When you auto-generate a form (as with SQLFORM), a random form key is generated and inserted into the form. The same key is also saved in the web2py server. When the form is submitted and web2py checks it with form.accepts, it first verifies that the submitted formkey is one that was previously generated by web2py. If the key is found, it is removed from the list of pending formkeys. If the key is not found, the form is reset. The point of this is to prevent people from accidentally submitting the same form twice (imagine accidentally clicking the submit button twice when submitting a credit card purchase). But I bet you're running into a case where you redirect and send the form vars, but the formkey is no longer valid (since it has already been generated and accepted once), so the form is reset after the redirect. Long story short, regenerate the form in the same request if there is an error - don't redirect unless there's some reason for this that I'm not realizing. Cheers, Kevin
[web2py] Re: web2py Issues
One other thought - if web2py wasn't rejecting the form based on the formkey after redirect, I think you would actually be running into an infinite redirect loop here the way things are currently structured! Cheers, Kevin
