            # qs_add.save()
            messages.add_message(request, messages.INFO, 'Employee save successfully')
            context['form'] = context['form'] = EmployeeForm()

        else:
            context['form'] = EmployeeForm(request.POST)
    else:
        context['form'] = EmployeeForm()
    
    return render(request, 'app/employee.html', context)

In your model Employee the field city is a ForeignKey for which the default form field is ModelChoiceField [Django docs]. This form field normalizes to a model instance. Assuming that you don't use some other form field you are not getting the choice text but an instance of City. Therefore you can simply write city.id or city.pk to get the id that you want, or you can simply write the follows:

city = form.cleaned_data['city'].pk

Also calling some procedure to insert values should not really be needed (unless for some reason you really want to save bandwidth), assuming you use a ModelForm you can simply write the follows to save the employee to the database:

employee = form.save()
