现在，当我填写表单并发送查询时，它没有显示任何错误，但再次显示输入字段值的表单，除了phone_code（它显示默认值）。没有显示错误，但表单未经过验证。我尝试了使用TemplateView和FormView的不同方法。但没有成功。需要任何帮助。
答案 0 :(得分：0)
您尚未将POSTed数据传递到任何地方的表单。
这是您不应该重写get和post方法的原因之一。各种基于类的视图的关键在于它们几乎为您完成所有这些操作。您应该继承CreateView，以便在表单有效时保存表单，并且您添加的额外逻辑应该在get_context_data中 - 如您所见，这可以避免必须包含相同的代码两次。 / p>
class VehicleStockDetailView(CreateView):
template_name = "site/product/vehicle-detail.html"
template_name_done = "site/contact/contact-us-done.html"
template_name_done_email = "site/contact/emails/contact-us-done.html"
form_class = VehicleInquiryForm
model = VehicleStock
def get_context_data(self, *args, **kwargs):
context = super(VehicleStockDetailView, self).get_context_data(*args, **kwargs)
context['vehicle'] = get_object_or_404(VehicleStock, slug=self.kwargs['slug'])
context['similar_vehicles'] = VehicleStock.objects.get_public_available().filter(model__id=vehicle.model.id).exclude(slug=slug)[:6]
context['page_title'] = vehicle.model
return context
def form_valid(self, form, *args, **kwargs):
obj = form.save()
return render(self.request, self.template_name_done, {'full_name': self.request.POST['full_name'], 'email': self.request.POST['email']})
另请注意，您确实不应该在成功时直接呈现模板;你应该总是重定向。同样，表单视图会为您解决此问题。
