How can I build multiple submit buttons django form?

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

<form action="" method="post">
{{ form_newsletter }}
<input type="submit" name="newsletter_sub" value="Subscribe" />
<input type="submit" name="newsletter_unsub" value="Unsubscribe" />

I have also class form:

class NewsletterForm(forms.ModelForm):
    class Meta:
        model = Newsletter
        fields = ('email',)

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 self.cleaned_data dictionary.
Could I get values of buttons otherwise?

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

# in the context of a django.forms form

def clean(self):
    if 'newsletter_sub' in
        # do subscribe
    elif 'newsletter_unsub' in
        # do unsubscribe


if 'newsletter_sub' in request.POST:
    # do subscribe
elif 'newsletter_unsub' in request.POST:
    # do unsubscribe

You can also do like this,

 <form method='POST'>
    <button type="submit" name="btnform1">Save Changes</button>
    <form method='POST'>
    <button type="submit" name="btnform2">Save Changes</button>


if request.method=='POST' and 'btnform1' in request.POST:
    do something...
if request.method=='POST' and 'btnform2' in request.POST:
    do something...

one url to the same view!
like so!

url(r'^$', views.landing.as_view(), name="landing"),

class landing(View):
        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,})
    <!-- #### form 1 #### -->
    <form action="" method="POST" >
      {% csrf_token %}
      {{ register.as_p }}
    <button type="submit" name="htmlsubmitbutton1">Login</button>
    <!--#### form 2 #### -->
    <form action="" method="POST" >
      {% csrf_token %}
      {{ login.as_p }}
    <button type="submit" name="htmlsubmitbutton2">Login</button>

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

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
       In template:
         <input type="submit" name="create_new" value="Create"/>
         <input type="submit" name="delete" value="Delete"/>
         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
                self.success_url = self.success_urls[name]

        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)
            raise ImproperlyConfigured(
                _("No URL to redirect to. Provide a success_url."))
        return url

I know this is old, but some of the answers are, to say the least, brief, and they do not address a common case where the form is not a django form.

This solution was inspired by this blog post. It relies on using a view class that is derived from django.views.generic.edit.FormMixin, e.g. CreateView, UpdateView or DeleteView. These provide the get_success_url method which exposes the button name in request


        <form method="post">
                <label> <input type="radio" name="select-type" value="A">Type A</label>
                <label> <input type="radio" name="select-type" value="B">Type B</label>
                <input type="submit" value="Use selected">
                <input type="submit" name="no-selection" value="None of the above">

from django.views.generic import UpdateView

class GetType(UpdateView):
    def get(self, request):
        return render(request, 'get_type.html', {})

    def post(self, request):
        button = self.get_success_url()

    def get_success_url(self):
        if 'no-selection' in self.request.POST:
            return 'none selected'
        return ''
