Показать измененный внешний ключ в выпадающем списке формы django

Question

Models.py

class Receiver_client(models.Model):
    name = models.CharField(max_length=255, default=0)
    city = models.CharField(max_length=255, default=0)
    address = models.CharField(max_length=255, default=0)
    partner = models.ForeignKey(Client, on_delete=models.CASCADE, related_name='client')

    def __str__ (self):
        return self.name

class OutwardDocket(models.Model):
    transaction_date = models.DateField(default=datetime.now)
    dispatch_date = models.DateField(default=datetime.now)
    sending_location = models.ForeignKey(Receiver_client, on_delete=models.CASCADE, related_name='receiver_location')

Views.py

@method_decorator([login_required, employee_required], name='dispatch')
class OutwardDocketFormView(CreateView):
    model = OutwardDocket
    form_class = OutwardDocketForm
    template_name = 'packsapp/employee/OutwardDocketForm.html'

    def form_valid (self, form):
        product = form.save(commit=False)
        product.save()
        messages.success(self.request, 'The OutwardDocket was created with success!')
        return redirect('employee:outward_table')

Forms.py

class OutwardDocketForm(forms.ModelForm):
    class Meta:
        model = OutwardDocket
        fields = "__all__"

        def __init__(self, *args, **kwargs):
            super().__init__(*args, **kwargs)
            self.fields['sending_location'].queryset = Receiver_client.objects.all()

Я могу показать список Reciever_client в моемФорма OutwardDocket, но как я могу изменить ее таким образом, чтобы она отображала имя, а также город клиента получателя?

Я не хочу изменять str в получателемодель клиента в том виде, в каком она используется в нескольких местах.
