How to create 2 Forms simultaneously in Django and configure the views

Question

What I want to do is create 2 Forms simultaneously, on just one page 'index.html'. One would just be a normal form that will send a message to contact, and the other is a record that I need to save to the database. So far I have been able to create only using a form, this way.

class IndexView(FormView):
template_name = 'index.html'
form_class = ContatoForm
success_url = reverse_lazy('index')

def get_context_data(self, **kwargs):
    context = super(IndexView, self).get_context_data(**kwargs)
    context['servicos'] = Servico.objects.order_by('?').all()
    context['funcionarios'] = Funcionario.objects.order_by('?').all()
    context['portfolios'] = Portfolio.objects.order_by('?').all()
    context['testimonials'] = Testimonial.objects.order_by('?').all()

    return context

def form_valid(self, form, *args, **kwargs):
    form.send_mail()
    messages.success(self.request, 'E-mail enviado com sucesso')
    return super(IndexView, self).form_valid(form, *args, **kwargs)

def form_invalid(self, form, *args, **kwargs):
    messages.error(self.request, 'Erro ao enviar e-mail')

    return super(IndexView, self).form_invalid(form, *args, **kwargs)

Now I needed to add another form, which is this

class RegistroModelForm(forms.ModelForm):
class Meta:
    model = Registro
    fields = ['nome', 'email', 'phone', 'area']

Alive, you can create multiples Forms, there is even inlineformset_factory among others, depends on the use case. Even here in this "class based Generic views", you can use a different one that best suits your case that Django provides, such as: View, Listview, Templateview, Createview, Deleteview, Updateview that you can import from Jango.views.Generic. Or simply use a function of yours that involves doing more code and validations than these base classes already do for you.

py views.

from django.views.generic import CreateView

class IndexView(CreateView):
    template_name = 'index.html'
    form_class = ContatoForm
    form_class_adicional = RegistroModelForm

    def get(self, request, *args, **kwargs):
        context = { 
            'form': self.form_class,
            'form_new': self.form_class_adicional(),
            'servicos': Servico.objects.order_by('?').all(),
            'funcionarios': Funcionario.objects.order_by('?').all(),
            'portfolios': Portfolio.objects.order_by('?').all(),
            'testimonials': Testimonial.objects.order_by('?').all()
        }
        return render(request, self.template_name, context)

    def post(self, request, *args, **kwargs):
        if request.method == 'POST':
            form = self.form_class(request.POST or None, request.FILES or None)
            form_new = self.form_class_adicional(request.POST or None, request.FILES or None)
            # aqui Django valida o teu form, neste caso só os dois válidos irá gravar, mas podes mudar esta lógica
            if form.is_valid() and form_new.is_valid(): 
                form.save()
                form_new.save()
                form.send_mail() # envias o email
                #messages.success(self.request, 'E-mail enviado com sucesso') # esta mensagem colocas na função send_mail
                #messages.error(self.request, 'Erro ao enviar e-mail')        # esta mensagem colocas na função send_mail
            return redirect('index')
        return redirect('index')

index.html

<form action="." enctype="multipart/form-data" method="POST">
    {% csrf_token %}
    {{ form }}
    {{ form_new }}
    <button type="submit" value="submit">Gravar</button>
</form>
