Re: Dynaically fields to a formwizard form

[Peter Bengtsson]

You can add and modify fields on a form in the form's __init__
function.

class MyForm(forms.Form):
country = forms.ChoiceField()
def __init__(self, *args, **kwargs):
 super(MyForm, self).__init__(*args, **kwargs)
self.fields['country'].choices = \
  [(c.iso_code, c.name) for c in get_all_choices()]

Perhaps you'll need to do it in the view.
You can create the form instance both before you bind it with
something like request.POST or if you do it later.
E.g.
def my_view(request):
form = MyForm()
form.fields['country'].choices = get_my_country_choices
(request.user)
if request.method == "POST":
# bind the form
form.is_bound = True
form.data = request.POST
if form.is_valid():
return render(request, 'my_template.html', locals())

cool!

Dynaically fields to a formwizard form

[dingue fever]

Hi,

Is it possible to dynamically add fields to a formwizard form. I have
been able to add the fields I want but if the form fails validation
the new dynamic fields disappear when the form re-renders. Is it
possible to override this so that I can validate and return the new
fields if the validation fails?

Thanks
