You can use <code>self.data</code> in the <code>clean_email</code> method to access the POST data before validation. It should contain a key called <code>newsletter_sub</code> or <code>newsletter_unsub</code> depending on which button was pressed.

<pre><code># in the context of a django.forms form

def clean(self):
 if 'newsletter_sub' in self.data:
 # do subscribe
 elif 'newsletter_unsub' in self.data:
 # do unsubscribe
</code></pre>

entityMap|blocks|key|d8fv1|text|现在这是一个老问题了，尽管如此，我还是遇到了同样的问题，并找到了一个适合我的解决方案:我写了MultiRedirectMixin。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|6blv3|from+django.http+import+HttpResponseRedirect

It's an old question now, nevertheless I had the same issue and found a solution that works for me: I wrote MultiRedirectMixin.

<pre><code>from django.http import HttpResponseRedirect

class MultiRedirectMixin(object):
 """
 A mixin that supports submit-specific success redirection.
 Either specify one success_url, or provide dict with names of 
 submit actions given in template as keys
 Example: 
 In template:
 &lt;input type="submit" name="create_new" value="Create"/&gt;
 &lt;input type="submit" name="delete" value="Delete"/&gt;
 View:
 MyMultiSubmitView(MultiRedirectMixin, forms.FormView):
 success_urls = {"create_new": reverse_lazy('create'),
 "delete": reverse_lazy('delete')}
 """
 success_urls = {} 

 def form_valid(self, form):
 """ Form is valid: Pick the url and redirect.
 """

 for name in self.success_urls:
 if name in form.data:
 self.success_url = self.success_urls[name]
 break

 return HttpResponseRedirect(self.get_success_url())

 def get_success_url(self):
 """
 Returns the supplied success URL.
 """
 if self.success_url:
 # Forcing possible reverse_lazy evaluation
 url = force_text(self.success_url)
 else:
 raise ImproperlyConfigured(
 _("No URL to redirect to. Provide a success_url."))
 return url

one url to the same view! 
like so!

urls.py

<pre><code>url(r'^$', views.landing.as_view(), name = 'landing'),
</code></pre>

views.py

<pre><code>class landing(View):
 template_name = '/home.html'
 form_class1 = forms.pynamehere1
 form_class2 = forms.pynamehere2
 def get(self, request):
 form1 = self.form_class1(None)
 form2 = self.form_class2(None)
 return render(request, self.template_name, { 'register':form1, 'login':form2,})

 def post(self, request):
 if request.method=='POST' and 'htmlsubmitbutton1' in request.POST:
 ## do what ever you want to do for first function ####
 if request.method=='POST' and 'htmlsubmitbutton2' in request.POST:
 ## do what ever you want to do for second function ####
 ## return def post### 
 return render(request, self.template_name, {'form':form,})
</code></pre>

<pre><code>/home.html
 &lt;!-- #### form 1 #### --&gt;
 &lt;form action="" method="POST" &gt;
 {% csrf_token %}
 {{ register.as_p }}
 &lt;button type="submit" name="htmlsubmitbutton1"&gt;Login&lt;/button&gt;
 &lt;/form&gt;
 &lt;!--#### form 2 #### --&gt;
 &lt;form action="" method="POST" &gt;
 {% csrf_token %}
 {{ login.as_p }}
 &lt;button type="submit" name="htmlsubmitbutton2"&gt;Login&lt;/button&gt;
 &lt;/form&gt;
</code></pre>

I have form with one input for email and two submit buttons to subscribe and unsubscribe from newsletter:

<pre><code>&lt;form action="" method="post"&gt;
{{ form_newsletter }}
&lt;input type="submit" name="newsletter_sub" value="Subscribe" /&gt;
&lt;input type="submit" name="newsletter_unsub" value="Unsubscribe" /&gt;
&lt;/form&gt;
</code></pre>

I have also class form:

<pre><code>class NewsletterForm(forms.ModelForm):
 class Meta:
 model = Newsletter
 fields = ('email',)
</code></pre>

I must write my own clean_email method and I need to know by which button was form submited. But the value of submit buttons aren't in <code>self.cleaned_data</code> dictionary.
Could I get values of buttons otherwise?

How can I build multiple submit buttons django form?

 我有一个输入电子邮件的表单和两个订阅和取消订阅时事通讯的提交按钮： {{ form_newsletter }} 我还有一个类表： class NewsletterForm(forms.ModelForm):    class Meta:        model = Newsletter        fields ...
