Question

我正在尝试创建类似于Hyrecar的租车网站。我根据Django教程“使用表单”创建了一个表单，但是我不知道如何呈现从POST表单中获得的信息。我想让我从POST获得的信息（预订名称，租金价格等）显示预订的汽车及其详细信息。汽车是booking.i中的外键字段，我想将其重定向到显示已预订汽车的页面。例如

预订名称：xyz
租赁价格：123
CAr ：carimage.jpg 4。

我想将其重定向到弹出页面。如果用户预订了汽车并发布了表格。之后，将其重定向到pop.html页面，并显示用户现在发布的预订详细信息。

Forms.py

class BookingForm(ModelForm):

 class Meta:
     model = Booking
     widgets = {
         'times_pick': forms.TimeInput(attrs={'class':'timepicker'}),

     }
     fields = ('booking_name','rental_price','book_car','customer_name','times_pick',)

urls.py

   [

   url(r'^booking/',views.BookingView.as_view(),name='car_booking'),

   url(r'^pop/$',views.PopView.as_view(),name='pop'),
 ]

views.py

  class CarDetailView(DetailView):
    context_object_name = 'car_details'
    model = models.Car
    template_name = 'buggy_app/car_detail.html'

class BookingView(FormView):
   template_name = 'buggy_app/booking.html'
   form_class = BookingForm
   models = Booking
   def form_valid(self, form):
       form.save()
        return super(BookingView, self).form_valid(form)

   success_url = reverse_lazy('index')

   def get_context_data(self, **kwargs):
       # kwargs['car'] is the car booking now!
        try:
           kwargs['car'] = Car.objects.get(id=self.request.GET.get('car', ''))
        except (Car.DoesNotExist, ValueError):
           kwargs['car'] = None

        return super(BookingView, self).get_context_data(**kwargs)

   def get_initial(self):
       initial = super(BookingView, self).get_initial()
       if 'car' in self.request.GET:
          try:
              initial['book_car'] = Car.objects.get(id=self.request.GET['car'])
           except (Car.DoesNotExist, ValueError):
            pass
       return initial

booking.html

    <form method="POST">
      {% csrf_token %}
      {% bootstrap_form form %}
      <input type="submit" class='btn btn-primary' value="Submit">

  </form>

尝试这样

def save_form(request):
   args = {}
   form = BookCarForm(request.POST)
   if form.is_valid():
       book = form.save(commit=False)
       book.book_car_mark = request.POST.get('car_mark')
       book.book_car_mmodel = request.POST.get('car_model')
       book.book_car_year = request.POST.get('car_year')
       book.book_car_mark = request.POST.get('car_mark')
       form.save()
       try:
           args['book'] = Book.objects.get(id=book.id)
       except:
           args['book'] = None
       if args['book'] is not None:
           return render(request, 'your_template.html', args)
       else:
           return HttpResponseRedirect('/your/url/to-booking-form/')

字段名称，因为模型和模板的名称是抽象的，因此它只是一种工作机制方案

如何呈现POST并使其显示在另一页上？以Django形式
