Why is the parent form inline formset not displayed?

Question

Django

class ExchangeRate(StampedModel):
    document = models.ForeignKey(DocExchangeRate)
    # another fields

ExchangeInlineFormset = inlineformset_factory(DocExchangeRate, ExchangeRate, fk_name='document', extra=1)

class DocExchangeRateCreateView(CreateView):
    model = DocExchangeRate

    def get(self, request, *args, **kwargs):
        from django.shortcuts import render
        self.object = None
        formset = ExchangeInlineFormset()
        return render(request, 'pricing/docexchangerate_form.html', self.get_context_data(formset=formset))

<form action="" method="post">{% csrf_token %}
        {{ form }}
        {{ formset.management_form }}
        {{ formset }}
        <input type="submit" class="submit"/>
    </form>

the inline formset is rendered, and after clicking submit, the main form is rendered. How to bring them together?

Answer 1

It turns out it is necessary to explicitly transfer to the context and the main form.
I was wrong in assuming that CBV will do this as well if get is not overridden.
