Django在单个页面/ url下的两个单独的表格

Question

我有两种形式，我想在网站的索引页上显示和使用。

索引页面是一个HomeView，它在上下文中包含两种形式 - ContactForm和SubscribtionForm。

我的目标是在单页上使用这两种形式。到目前为止，这是不可能的，因为每次验证失败时，它都会重定向到查看哪个负责表单验证。

的片段索引页面的html代码：

<form id="contact-form" class="contact form-horizontal" action="{% url 'contact' %}" method="post" novalidate> 

<form id="newsletter-form" class="newsletter_form" action="{% url 'subscribe' %}" method="post" novalidate> 

我怎么做在Django，当我提出将使用其他视图来验证和保存数据，但响应将被显示的索引页？我应该使用javascript/ajax调用来解决这个问题吗？或者有另一种方式？

编辑：

class SubscriberFormView(FormView): 
    form_class = SubscriberForm 
    template_name = 'home/subscriber_form.html' 

    def get_success_url(self): 
     return reverse('home') 

    def form_valid(self, form): 
     form.save() 
     return redirect(self.get_success_url()) 


class ContactFormView(FormView): 
    form_class = ContactForm 
    template_name = "home/contact_form.html" 

    def form_valid(self, form): 
     instance = form.save() 
     instance.send_confirmation() 
     instance.send_notification() 
     return redirect(self.get_success_url()) 

与前缀替代解决方案：基于

class HomeView(FormMixin, TemplateView): 
    template_name = 'index.html' 
    form_class = ContactForm 
    form_class_sub = SubscriberForm 

    def get_success_url(self): 
     return reverse('home') 

    def get_forms(self): 
     contact_kwargs = self.get_form_kwargs().copy() 
     contact_kwargs['prefix'] = 'contact' 
     sub_kwargs = self.get_form_kwargs().copy() 
     sub_kwargs['prefix'] = 'sub' 
     return { 
      'contact_form': self.form_class(**contact_kwargs), 
      'subscription_form': self.form_class_sub(**sub_kwargs), 
     } 

    def post(self, request, *args, **kwargs): 
     forms = self.get_forms() 
     if 'contact-submit' in request.POST: 
      form = forms['contact_form'] 
      form_name = 'contact_form' 
     elif 'newsletter-submit' in request.POST: 
      form = forms['subscription_form'] 
      form_name = 'subscription_form' 
     else: 
      raise Http404 

     if form.is_valid(): 
      return self.form_valid(form) 
     else: 
      return self.form_invalid(form, form_name) 

    def form_invalid(self, form, form_name): 
     return self.render_to_response(self.get_context_data()) 

    def get_context_data(self, **kwargs): 
     data = super().get_context_data(**kwargs) 
     if 'contact_form' not in data: 
      data['contact_form'] = self.get_forms()['contact_form'] 
     if 'subscription_form' not in data: 
      data['subscription_form'] = self.get_forms()['subscription_form'] 
     return data 

    def form_valid(self, form): 
     instance = form.save() 
     return super().form_valid(form) 

功能视图（指数）：

def index(request): 
    contact_form = ContactForm(request.POST or None, prefix='contact') 
    subscription_form = SubscriberForm(request.POST or None, prefix='sub') 

    if request.method == "POST": 
     if 'contact-submit' in request.POST: 
      form = contact_form 
     elif 'sub-submit' in request.POST: 
      form = subscription_form 
     else: 
      raise Http404 

     if form.is_valid(): 
      form.save() 

    return TemplateResponse(request, template="index.html", context={ 
     'contact_form': contact_form, 
     'subscription_form': subscription_form, 
    }) 

最终版本：

def index(request): 
    contact_form = ContactForm(None, prefix='contact') 
    subscription_form = SubscriberForm(None, prefix='sub') 

    if request.method == "POST": 
     if 'contact-submit' in request.POST: 
      contact_form = ContactForm(request.POST, prefix='contact') 
      if contact_form.is_valid(): 
       contact_form.save() 
     elif 'sub-submit' in request.POST: 
      subscription_form = SubscriberForm(request.POST, prefix='sub') 
      if contact_form.is_valid(): 
       contact_form.save() 
     else: 
      raise Http404 

    return TemplateResponse(request, template="index.html", context={ 
     'contact_form': contact_form, 
     'subscription_form': subscription_form, 
    })

您不应该使用不同的视图来验证数据。表单应该在已渲染的相同视图中进行验证。

为了能够在一个视图中使用多个表单，只需使用形式前缀： https://docs.djangoproject.com/en/1.8/ref/forms/api/#prefixes-for-forms
