the problem:
on a form validation error a checked box (Bool) loses its state on
the form refresh
setup:
a form created with a tw.form.TableForm, TextField, CheckBox
a formencode.validator Bool and i used Email
the widget:
class form_w(TableForm):
fields = [
TextField ('email', is_required=True, label_text="Email",
validator=Email()),
CheckBox('want_info', label_text='Want_info',
default=True,
validator=Bool()
]
Email_form = form_w('Email_form', action="email_capture",
submit_text='submit')
the Controller:
@expose(pws.template.index)
def index(self, **kws):
tmpl_context.form=Email_form
return dict(page='index', data=kws)
@expose(pws.template.index)
def index_validate(self, **kws):
tmpl_context.form = Email_form
return dict(page='index', data=kws)
@validate(Email_form, error_handler=index_validate)
@expose(pws.template.index)
def email_capture(self, **kws):
flash("capture the data %s" %kws)
tmpl_context.form=Email_form
return dict(page='index', data=kws)
1)when the form is initialized the check box is ticked.
2)i put in the email address incorrectly, untick the box, submit it.
3) i get the email error and the check box is ticked again.
if i get the email correct the check box keeps it state correctly
the tmpl_context.form_values have the same info as the kws
to make it work correctly in the def index_validate i add
if not kws.has_key('want_info'):
kws['want_info'] = False
the formencode does know this as it has a if_missing=False which is
returned should the validation be sucessful.. it is not added to the
return result when missing because the browser didn't send back the
information.
i think this is a bug. as the validation on the box was correct it
should have poked in the missing dict key=False in the
tmpl_context.form_values as they represent the python side which
1)then are used to be sent back out on the validation_form.
2)when officially passed validation is returned with the correct False
entity
should the validation be sucessful even the kws has a
kws['want_info']=False in it. the problem is only when the form does
not validate.
