Как соединить несколько цепочек выпадающих элементов с помощью django-forms-dynamic

У меня есть форма с контрагентом, объектом и разделами, я соединил их друг с другом с помощью пакета django-forms-dynamic, но объект не соединен с разделами

Контрагент подключен к форме объекта, но секции не подключены к объекту, как это исправить?

Я предполагаю, что я ошибся с 2 функциями в forms.py: section_choices и initial_sections и они не связаны с объектами, но не знаю, как это исправить

forms.py

class WorkLogForm(DynamicFormMixin, forms.ModelForm):

    def object_choices(form):
        contractor_counter = form['contractor_counter'].value()
        object_query = ObjectList.objects.filter(contractor_guid__in=[contractor_counter])
        return object_query

    def initial_object(form):
        contractor_counter = form['contractor_counter'].value()
        object_query = ObjectList.objects.filter(contractor_guid__in=[contractor_counter])
        return object_query.first()

    def section_choices(form):
        contractor_object = form['contractor_object'].value()
        section_query = SectionList.objects.filter(object=contractor_object)
        return section_query

    def initial_sections(form):
        contractor_object = form['contractor_object'].value()
        section_query = SectionList.objects.filter(object=contractor_object)
        return section_query.first()

    contractor_counter = forms.ModelChoiceField(
        label='Контрагент',
        queryset=CounterParty.objects.none(),
        initial=CounterParty.objects.first(),
        empty_label='',
    )

    contractor_object = DynamicField(
        forms.ModelChoiceField,
        label='Объект',
        queryset=object_choices,
        initial=initial_object,
    )

    contractor_section = DynamicField(
        forms.ModelMultipleChoiceField,
        label='Раздел',
        queryset=section_choices,
        initial=initial_sections,
    )

views.py

    if request.method == 'POST':
        form = WorkLogForm(request.POST, user=request.user)

            work_log = form.save(commit=False)

    return render(request, 'contractor/create_work_log.html', {'form': form})

    form = WorkLogForm(request.GET, user=request.user)
    return HttpResponse(form['contractor_object'])

    return HttpResponse(form['contractor_section'])
