Hi,

I want to acces request.vars.name_of_my_field, with
request.vars['name_of_my_field'] with boolean field but if the field
is unchecked (false) I got a KeyError like if field was not existing.

Here is an example controller:

def main():

    list_field = ['a','b','c']

    form = SQLFORM.factory(
        Field('a','boolean'),
        Field('b','boolean'),
        Field('c','boolean'))

    if form.accepts(request.vars,session, keepvalues=True):

        for field in list_field:
            print request.vars[field]

    return dict(form=form)

If I check all three field everything works fine, but if one field is
unchecked I got a key error when I try to access it.

It is like the field doesn't exist until it is checked..?? doesn't
make any sense to me...
