form.accept problem

[jldistefano]

Hi Massimo, Hi all.

I am new to web2py and I really like it.
can anyone tell me what is wrong with this code, there is no
validation at all, it display page2 directly without showing the
form.

def index():

form=FORM('your name:',
INPUT(_name="name"),
INPUT(_type="submit"))
if form.accepts(request.vars,formname=None):
session.name=form.vars.name
session.flash='you have been redirected'
redirect(URL(r=request,f='page2'))
elif form.error:
response.flash='there are errors in your form'
return dict(form=form)

def page2():
return dict(message='hello %s'%session.name)

In default/index.html there is only a {{=form}}

Thanks in advance.

I only see one problem:

>  elif form.error:

should be

> elif form.errors:

[mdipierro]

make sure sessions are on by commenting the line

session.forget()

[jldistefano]

Massimo,

The line session.forget() is deleted, and now the elif form.error:
block too, and things don't change.
when the code is run there is no validation and page2 is shown
directly without showing index page with the form.
What other things can I check?

Thanks for your attention.

[Massimo Di Pierro]

You must give a name to the form else web2py thinks the form has been
submitted but it is empty.

[jldistefano]

Yes thats it!! now is working.
if form.accepts(request.var,formname="myform")
.....
.....

and without the elif form.error: block

Massimo, I spend lots of hours traying to figure what was wrong, I saw
a lot of code in diferent places (cookbook, examples, vids, draft
manual here in the group) and in all I found diferent code that
suppouse to do the same.
for example why - if form.accepts(session.var,session) - do not work.
Like I said I'm very new with web2py and also may be not so smart
like others in this group.
I realy belive that you have developed a very very good piece of
software , but also belive that DOCUMENTATION is not well presented
and this is, if not the most important, a big issue if you want to be
compared with the others frameworks (Zope, Django, TG), you as a
teacher understand what I am talking about.

Sorry for my poor english.
Congratulations, and thanks for your excelent work !!
And keep going this way

Did you get the draft book form the web site? I am trying to finish
that.

[jldistefano]

If you refer Draft Book to the Draft Manual, yes I get it !!, is my
principal guide, and for example I didn' t found there the syntax "if
form.accepts(request.var,formname="myform") "

Bye

[Massimo Di Pierro]

No but form.accepts(request.var,session) is in there and that is the preferred way since it prevents double submission.

I don't think I ever suggested using formname=None. I may have on the list in response to a very specific question.

Continuing with the chat, what I found in the example said,
form.accepts(session.var,session) and this throw this ticket in my
code.

form.acceps(request.var,session) works

[Massimo Di Pierro]

> form.accepts(session.vars,session)

not

> form.accepts(session.var,session)

could this be the problem?

[jldistefano]

I don't know .
I didn't put the S in session.var

[mdipierro]

Than that's it. accepts expects a dictionary-like object as first
argument. If you pass var instead of vars, since var it is undefined,
it stores None. This propagates and causes an error.

[jldistefano]

CORRECTION !! The ticket above was produced with
form.accepts(session.vars,session) with the S on var.
Sorry.

[Massimo Di Pierro]

can you send me the ticket and possibly the code?

[Massimo Di Pierro]

please send me your code and I will look it at (privately if you want).
