*I have a dinamic form wizard step as following:*
class AltaForm6(forms.Form):
CHOICES = ((1, 1,), (2, 2,))
username = ChoiceFieldInvalid(required=True, label="Usuario",
widget=forms.RadioSelect, choices=CHOICES)
username2 = forms.CharField(required=False, label="Otro")
def clean_username2(self):
username = self.cleaned_data.get('username')
username2 = self.cleaned_data.get('username2')
if username == "Otro" and len(username2) == 0:
raise forms.ValidationError("Debe especificar un nombre de usuario")
return username2
def clean_username(self):
username = self.cleaned_data.get('username')
return username
*Then i dynamically change the choices values:*
class AltaWizard(SessionWizardView):
template_name = 'agroshare/wizard.html'
def get_form(self, step=None, data=None, files=None):
form = super(AltaWizard, self).get_form(step, data, files)
if step == '5':
import logging
logger = logging.getLogger(__name__)
cleaned_data = self.get_cleaned_data_for_step('2') or {}
logger.error(cleaned_data)
nombre = cleaned_data.get('nombre')
apellido = cleaned_data.get('apellido')
first = possibleUid(nombre, apellido, '1')
second = possibleUid(nombre, apellido, '2')
if ' ' in nombre:
third = possibleUid(nombre, apellido, '3')
form.fields['username'].choices = ((first, first,), (second,
second,), (third, third,), ("Otro", "Otro",))
if ' ' in apellido:
fourth = possibleUid(nombre, apellido, '4')
form.fields['username'].choices = ((first, first,), (second,
second,), (fourth, fourth,), ("Otro", "Otro",))
else:
form.fields['username'].choices = ((first, first,), (second,
second,), ("Otro", "Otro",))
if step == '5':
form.user = self.request.user
return form
def render(self, form=None, **kwargs):
form = form or self.get_form()
context = self.get_context_data(form=form, **kwargs)
if self.steps.current == '5':
form2 = self.get_form('5')
cleaned_data = self.get_cleaned_data_for_step('5') or {}
username = cleaned_data.get('username')
form2.fields['username'].choices = [username]
return self.render_to_response(context)
*The problem is, when i go back to this step trough the wizard, it does not
modify the "choices" values, it shows "CHOICES = ((1, 1,), (2, 2,))"*
* *
*How can i achieve that when i go back to this step, the form can actually
show the values i want?*
