Django ModelForm Foreign Key Dropdown passes __str__ but stores fkey_id

Guys I need quick help.

There are two models and I would like to store a column field from one model to another model.

models.py:

class Company(models.Model):     name = ...   def __str__(self):           return self.name    class Rate(models.Model):     company = models.ForeignKey(Company)     currency = ...     name = ...     def __str__(self):           return self.name + " " + self.currency    class Client(models.Model):     name = ...     currency = ....     company = models.ForeignKey(Company)     base_rate = models.ForeignKey(Rate)     def __str__(self):           return self.name

forms.py:

class ClientForm(forms.ModelForm):      class Meta:          model = Client          fields = (                 "name",                                 "company",                 "base_rate", )

views.py:

class ClientCreateView(FormView):      template_name = "client/new_package.html"      form_class = ClientForm      success_url = reverse_lazy("home")        def form_valid(self, form):          detail = form.save(commit=False)          base_rate_id = form.cleaned_data['base_rate']          detail.currency = Rate.objects.values_list("currency", flat=True).filter(base_rate_id=base_rate_id)          detail.save()            if detail is not None:              return redirect('display_package' , detail.id)          else:              return super(ClientCreateView, self).form_valid(form)

Basically, I want selected currency value to be saved in my client model from Rate model. Any help will be appreciated as from cleaned data I am getting str returned value instead of selected option id value (i.e. str from client model ).
