How can use form_class with extra fields

[flaudizio]

Hi,

with betterforms can possible to use form_classes with more one field (like extra from inlineformset_factory) ?

Thank's a lot.

Hi @flaudizio,

Are you talking about MultiForm?

You can use an a FormSet inside of a MultiForm. There is an example of using an inline formset inside of a MultiForm in the tests: https://github.com/fusionbox/django-betterforms/blob/master/tests/forms.py#L129-L146

Is that what you were thinking?

Hi, thank's a lot.

One else thing, when I save in view I get this error:

can't set attribute

multiform.py in is_valid:

       try:

           cleaned_data = self.clean()

       except ValidationError as e:

           self.add_crossform_error(e)

       else:

           if cleaned_data is not None:

               for key, data in cleaned_data.items():

                   self.forms[key].cleaned_data = data

...

       return forms_valid and not self.crossform_errors

   def non_field_errors(self):

       form_errors = (

           form.non_field_errors() for form in self.forms.values()

           if hasattr(form, 'non_field_errors')

My forms.py

class ContactForm(ModelForm):
class Meta:
model = Contact
fields = ['name']

class PhoneForm(ModelForm):
class Meta:
model = Phone
fields = ['number']

PhoneInlineFormSet = inlineformset_factory(Contact, Phone,
fields=('number',), extra=3)

class ContactPhoneForm(MultiModelForm):
form_classes = {
'contato': ContactForm,
'telefone': PhoneInlineFormSet,

}

def __init__(self, *args, **kwargs):
    instance = kwargs.pop('instance', None)
    if instance is not None:
        kwargs['instance'] = {
            'contact': instance,
            'phone': instance,
        }
    super(ContactPhoneForm, self).__init__(*args, **kwargs)

In my views.py

class ContactCreate(CreateView):
form_class = ContatoTelefoneForm
template_name = "forms/contato.html"
success_url = reverse_lazy('home')
success_message = "Contato cadastro com sucesso."

def form_valid(self, form):

    contato = form['contact'].save()
    telefone = form['phone'].save(commit=False)

    telefone.contato = contato
    telefone.save()

    return super(ContactCreate, self).form_valid(form)

def get_success_url(self):
    redirect_to = self.success_url
    if not is_safe_url(url=redirect_to, host=self.request.get_host()):
        redirect_to = self.success_url
    return redirect_to

Once again, very thank you.

Oh darn, I think you are running into the #41 bug. I'm going to close this bug in favor of that one. I think perhaps I have a solution for it in the #44 PR.

Hi,

can you show the example using inline ?

I just haven't this (in view):

AttributeError
'list' object has no attribute 'contato'

contato = form['contato'].save()
telefone = form['telefone'].save(commit=False)
telefone.contato = contato
telefone.save()

Thank's and sorry for work.
