[web2py] Re: Best practice for prepopulating regular form

[MichaelF]

Jim,

Thanks. I had already tried that, and it doesn't work for me. I wrote a 
little controller to test it:

@auth.requires_login()
def test_vars():
   form = FORM(
       FIELDSET('Subject: ', INPUT(_name='subject')),
       FIELDSET('Other subject: ', INPUT(_name='otherSubject')),
       FIELDSET('Recipients: ', INPUT(_name='recips', )),
       FIELDSET('Message: ', TEXTAREA(_name='message')),
       INPUT(_type='submit', _value='send', _name='sendBtn'),
       INPUT(_type='submit', _value='cancel', _name='cancelBtn')
       )

   if form.accepts(request, keepvalues=True):
      response.flash = 'oky'
   elif form.errors:
      response.flash = 'form has errors'
   else:
      form.vars.subject = 'my subject'
      form.element(_name='otherSubject')['_value'] = 'other subject'

   return dict(form=form)

I have no view, so I get the default. The form I see displayed has a blank 
for the field 'subject', and the field 'otherSubject' is filled with 'other 
subject'.

Now, that said, I could *easily* believe I'm screwing something else up. If 
that example works on your system, then there's something else I'm doing 
wrong. Thoughts?
