Question

我本来可以发誓这是在过去工作，但显然我没有像我应该的那样进行测试。我有一个表单，允许用户请求有关特定房地产列表的信息。有四（4）个单独的视图，一个用于显示所有，另外三个只是按属性过滤列表，即租赁，仅限房地产等。

表单的工作原理应该在视图中列出objects.all（），我想我可以在其他视图中调用form_class，但是当我在一个被过滤的页面上时，表单不起作用...在浏览器或其他任何内容中没有错误消息，电子邮件永远不会到达我们的收件箱。

如果您可以查看我的观点并提供一些反馈，我将非常感激，如果您需要查看其他任何信息，请告诉我。谢谢。

Class-based views（和some neat Django shortcuts）拯救：

from django.core.mail import send_mail
from django.views import generic
from django.template import render_to_string


class ContactFormView(generic.FormView):
    form_class = ContactForm
    template_name = 'listing/listing_list.html'
    success_url = 'listings'
    location_type = None

    def get_context_data(self, **kwargs):
        context = super(ContactFormView, self).get_context_data(**kwargs)
        context['listings'] = (Listing.objects
                               .filter(location_type=self.location_type)
                               .order_by('listing_order'))
        return context

    def form_valid(self, form):
        message = render_to_string('contact_template.txt', form.cleaned_data)
        send_mail('Form Submission from Listings Page', message,
                  form.cleaned_data['contact_email'])
        return super(ContactFormView, self).form_valid(form)


class FullService(ContactFormView):
    location_type='FULL_SERVICE'


class QuickServe(ContactFormView):
    location_type='QUICK_SERVE'
