don't worry, it's a mistake you'll probably never do again :P

[web2py] Re: how do I create, multiple forms and precess them, using 'for' statement?
I have chosen to go the custom form way.
The only issue I have is that upon hitting submit, the button submits all
the forms on the page instead of just the one owning the button. I think
this also screws up my validation and it prevents records from being
inserted to the db.
controller:
def show_form():
users_1 =
db(db.people.id.belongs(session.people.keys())).select(db.people.user_id)
users_2=[]
for user in users_1:
if user not in users_2:
users_2.append(user)
else:
pass
forms=[]
for user in users_2:
usr= db(db.auth_user.id==user.user_id).select(db.auth_user.username,
db.auth_user.id)[0]
usr1=usr.username
usr2=usr.id
key=str(usr2)
fields = [
Field('key',default=key,writable=False),
Field('username',default=usr1,writable=False),

address',type='text')
]

[web2py] Re: how do I create, multiple forms and precess them, using 'for' statement?
form.process adds little bits to the form to be able to actually process
the posted data.
in pseudo-code you need to
list_of_forms = []
for something in list_of_values:
key = something_unique
form = SQLFORM()
if form.process(formname=something_unique).accepted:
.code dealing with the posted values, such as form.vars, etc
elif form.errors:
.code dealing with form errors
list_of_forms.append(form)
..
return dict(list_of_forms=list_of_forms, )
In the view, you can then:
{{for single_form in list_of_forms:}}
{{=single_form}} #or {{single_form.custom.etc etc etc}}
{{pass}}

[web2py] Re: how do I create, multiple forms and precess them, using 'for' statement?
Thanks, I understand what you mean. I left the form.accepts out as it wasn't relevant to my question (and am still designing it) but thanks for pointing it out anyway! I'm going to struggle with the unpacking part for a while and thanks for not spoonfeeding me the code! The goal is me actually learning something ;) after a few months I'm finally at a point where I can grasp the concepts and code somewhat.

[web2py] Re: how do I create, multiple forms and precess them, using 'for' statement?
you are returning only the last form... you need to make a dict or a list out of the single form you generate in the for loop, and then in the view you can "unpack" them separately in my code, you can see on #L296 how every single form is appended to "forms", that is a list and that list is returned to the view. Also, you're leaving out form.accepts (or form.process )... you can't access form data in your controller without it -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] Re: how do I create, multiple forms and precess them, using 'for' statement?
Hi Niphlod,
I studied your example, but can't quite get it to work yet. I also tried
taking a look at your view but it's to complicated for me.
The only issue I'm having now is that the key isn't incrementing from the
view side. Can I pass the key in the view like {{=form+key}} or something?
Maybe I'm screwing up my controller.
controller:
def show_form():
users_1 =
db(db.people.id.belongs(session.people.keys())).select(db.people.user_id)
users_2=[]
for user in users_1:
if user not in users_2:
users_2.append(user)
else:
pass
for user in users_2:
usr=
db(db.auth_user.id==user.user_id).select(db.auth_user.username,db.auth_user.id)[0]
usr1=usr.username
usr2=usr.id
key=str(usr2)
fields = [
Field('username',default=usr1,writable=False)
]
form=SQLFORM.factory(*fields, table_name=key,hidden=dict(ss_id=key))
return dict(form=form, users_2=users_2,usr1=usr1,usr2=usr2,key=key)
View:
{{extend 'layout.html'}}
Form:
{{for user in users_2:}}
{{=form}}
{{pass}}
custom form:
{{=form.custom.begin}}
{{for user in users_2:}}
User: {{=form.custom.widget.user}}
{{pass}}
{{form.custom.end}}
manual form: gives the correct results
{{for user in users_2:}}
{{
usr=
db(db.auth_user.id==user.user_id).select(db.auth_user.username,db.auth_user.id)[0]
usr1=usr.username
usr2=usr.id
key=str(usr2)
}}
KEY:{{=key}}
username: {{=usr1}}
{{pass}}
I prefer to use the {{form.custom.widget[Field]}} tags.
Can you tell me what I'm doing wrong?

[web2py] Re: how do I create, multiple forms and precess them, using 'for' statement?
you just need to figure out a "key" to separate different forms, and use formname accordingly as stated in the book.

[web2py] Re: how do I create, multiple forms and precess them, using 'for' statement?
I understand that I need to use different formnames, I just don't
understand how I would syntax it do that automatically.
A single form will not suffice; I think is has to be different forms. I
need a uuid for each user and create/update several records for each user.
Basically I need to use something like:
def show_form():
for user in users:
form= SQLFORM.factory()
return dict(form=form)
But then in a way that works. I tried several ways, but am still
unsuccessful...
I read (, re-read and re-re-read) the chapter on forms in 'the book' but
there's no mention on how to achieve something like this, neither in the
examples.
I tried digging through a lot of the sample apps too but nothing.
I understand this is not the basic way forms are designed to be used but is
it that uncommon to do this?
I also tried:
for user in users:
form[user]= SQLFORM.factory()
return dict(form[user]=form[user])
this throws a global name form is not defined.
I also tried:
for user in users:
form = SQLFORM.factory()
form[user] = form
any ideas?

What does the model look like? You amy want to create a single form with
fields for each user.

you need to use different formname(s) to be able to process them separately.
