{{=form.custom.begin}} - How set an ID to form

[arnaud]

Hi,
I'm newbie with python and Web2Py. My problem : I want customize my
register form.

This is my code

#model
auth_table = db.define_table(auth.settings.table_user_name,
Field('first_name', length=128, default=''),
Field('last_name', length=128, default=''),
Field('email', length=128, default='', unique=True),
Field('password', 'password',length=256,readable=False,
label='Password'),
Field('registration_key', length=128, default= '',writable=False,
readable=False),
Field('orgUrl','string'),
Field('orgName','string'),
Field('orgAddress1','string',widget=patternNormal),
Field('orgAddress2'),
Field('orgZipCode'),
Field('orgCity1'),
Field('orgCountry','string'),
Field('orgDescription','text'),
Field('orgActivityDomain','string'),
Field('orgLogo','upload'),
Field('acceptCgi','boolean'),
Field('acceptMailing','boolean'),
Field('locale',default='fr_FR',writable=False,readable=False)
)

#controller
def register():
return dict(form=auth.register())

#view
{{=form.custom.begin}}
{{=form.custom.widget.first_name}}
...
{{=form.custom.end}}

{{=form.custom.begin}} serialize this code : <form method="post"
enctype="multipart/form-data" action="">

I want to set an ID to this form. What's the best way for achieve my
goal ?

Thanks

What do you mean by setting an ID?

[Thadeus Burgess]

he wants a HTML CSS id on the form.

aha

form=SQLFORM(.....,_id='thisformid')

or

form['_id'] = 'thisformid'

the latter works with crud forms too. Remember that

class SQLFORM(FORM): ... is a helper.

Yes but with crud, or in his case auth.register_form()

-Thadeus

[mdipierro]

It is the same

def register():
form=auth.register_form()
form['_id'] = 'my_form_id'
return dict(form=form)

Hi Massimo,

when I test your code (platform : windows / web2py 1-754), it's return
the following error :

Traceback (most recent call last):
File "gluon/restricted.py", line 173, in restricted
File "C:/dev/web2py1754/applications/sites/controllers/user.py",
line 21, in <module>
File "gluon/globals.py", line 96, in <lambda>
File "C:/dev/web2py1754/applications/sites/controllers/user.py",
line 8, in register
AttributeError: 'Auth' object has no attribute 'register_form'

[mdipierro]

Sorry by bad

def register():
form=auth.registe()

form['_id'] = 'my_form_id'
return dict(form=form)

[mdipierro]

def register():
form=auth.register()

form['_id'] = 'my_form_id'
return dict(form=form)

[arnaud]

Thanks Massimo, but this code has no effect. No ID is set to form.
SQLform is maybe the good solution.

[mdipierro]

It does work:

$ python web2py.py -S welcome -M

>>> form=auth.register()
>>> form['_id'] = 'my_form_id'

>>> print form.xml()
<form action="" enctype="multipart/form-data" id="my_form_id"
method="post">....</form>

perhaps I misunderstood the question and you expect something
different?

[arnaud]

Massimo,

no misundestood. I expect a css ID in my form.

I have run the same test on welcome app. That's work fine.

But in my app, no ID for my form.

It's perhaps a "bug" in view with the tag {{=form.custom.begin}}.

[DenesL]

The problem is that form.custom.begin is evaluated when the form is
created.
Changing '_id' after it has been created does not recalculate
form.custom.begin, but you can do so manually:

form['_id']='my_form_id'
form.custom.begin=XML("<%s %s>") %(form.tag,form._xml()[0]))

Denes.

[mdipierro]

You are right. Perhaps it should be re-initialized inside accept? What
do you think?

[DenesL]

The id is only one case.
You would have to recreate the whole thing to be sure everything is
updated but that makes it slower.

Ideally you would do these things at form creation or by setting
defaults beforehand ala field defaults.
Doing it at form creation means allowing **attributes in any function
that creates a form.

[Thadeus Burgess]

And hence the inherent flaw in SQLFORM :)

Though I can't complain since I have not devoted time to redesigning
the system as I so very much would like to do.

[Thadeus Burgess]

and for the record SQLFORM freaking rocks. It just needs to be
redesigned with customization in mind.

-Thadeus

[DenesL]

What do you mean?
SQLFORM is a FORM so you can pass **attributes.

form=SQLFORM(db.person,_id='myid')

Sorry for the delay. Your Solution works fine for me.

Thanks a lot
