Question

我可以发誓这是过去工作，但显然我没有测试，因为我应该有。我有一个表格，允许用户请求关于特定房地产列表的信息。有四（4）个单独的视图，其中一个显示所有，另三个简单地按属性过滤列表，即租赁，仅限于房地产等。

表单的工作方式应该像它应该在视图中列出对象.all（）和我以为我可以在我的其他视图中调用form_class，但是当我在被过滤的页面上时，表单不起作用...浏览器中没有错误消息或任何东西，电子邮件只是从来没有到达我们的收件箱。

如果你可以看看我的观点并提供一些反馈，我将非常感激，请让我知道如果你需要看到任何其他的东西。谢谢。

Class-based views（和someneat Django的shortcuts）救援：

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'
