DJANGO: Save two forms within one class-based view - django

Question

I have difficulties saving 2 forms within one view the only first one is saving but I cant figure out how to save the second one. Here is my code and issue :
models.py
class Office(models.Model):
name = models.CharField(max_length=100,null=True)
Address = models.ForeignKey(Address, on_delete=models.CASCADE, related_name='officeAddress',blank=True,null=True)
def __str__(self):
return self.name
class Address(models.Model):
address_line = models.CharField(max_length=60, blank=True)
address_line2 = models.CharField(max_length=60, blank=True)
country = models.ForeignKey(Country, on_delete=models.CASCADE, related_name='District')
province=ChainedForeignKey(Province,chained_field="country",chained_model_field=
"country",show_all=False,auto_choose=True,sort=True)
district=ChainedForeignKey(District,chained_field="province",
chained_model_field="province",show_all=False,auto_choose=True,sort=True)
class Meta:
verbose_name = "Address"
verbose_name_plural = "Addresses"
forms.py
class OfficeModelForm(BSModalModelForm):
class Meta:
model = Office
fields = ['name']
class AddressForm(forms.ModelForm):
class Meta:
model = Address
fields = ['address_line','address_line2','country','province','district']
views.py
class OfficeCreateView(BSModalCreateView):
form_class = OfficeModelForm
second_form_class = AddressForm
template_name = 'settings/create_office.html'
success_message = 'Success: Office was created.'
success_url = reverse_lazy('company:office-list')
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['address'] = self.second_form_class
return context
create_office.html
{% load static i18n %}
{% load widget_tweaks %}
<form method="post" action="" enctype="multipart/form-data">
{% csrf_token %}
{{ address.media.js }}
<div class="modal-body">
<div class="form-group">{% render_field form.name %}</div>
<div class="form-group">{% render_field address.address_line %}</div>
<div class="form-group">{% render_field address.address_line2 %}</div>
<div class="form-group">{% render_field address.country %}</div>
<div class="form-group">{% render_field address.province %}</div>
<div class="form-group">{% render_field address.district %}</div>
<button class="btn btn-primary ms-auto" type="submit">{% trans "Create new office" %}</button>
</div>
</form>
I think I need first to save the address then use the address.id as a foreign key for office but I don't know how to do this in CBV.
Thanks for your help...

You should change models base names. Example:
class OfficeCreateView(CreateView) instead class OfficeCreateView(BSModalCreateView)
or
class OfficeModelForm(form.ModelForm) instead class OfficeModelForm(BSModalModelForm)
