Jak mogę zbudować wiele przycisków wyślij formularz django?
Mam formularz z jednym wejściem na e-mail i dwoma przyciskami submit, aby zapisać się i wypisać się z newslettera:
<form action="" method="post">
{{ form_newsletter }}
<input type="submit" name="newsletter_sub" value="Subscribe" />
<input type="submit" name="newsletter_unsub" value="Unsubscribe" />
</form>
Mam też formę klasową:
class NewsletterForm(forms.ModelForm):
class Meta:
model = Newsletter
fields = ('email',)
Muszę napisać własną metodę clean_email i muszę wiedzieć, za pomocą którego przycisku został przesłany formularz. Ale wartość przycisków submit nie znajduje się w słowniku self.cleaned_data
.
Czy Mogę uzyskać wartości przycisków w przeciwnym razie?

Możesz użyć self.data
w metodzie clean_email
, aby uzyskać dostęp do danych POST przed walidacją. Powinien on zawierać Klawisz o nazwie newsletter_sub
lub newsletter_unsub
w zależności od tego, który przycisk został naciśnięty.
# 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

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

Możesz też zrobić tak,
<form method='POST'>
{{form1.as_p}}
<button type="submit" name="btnform1">Save Changes</button>
</form>
<form method='POST'>
{{form2.as_p}}
<button type="submit" name="btnform2">Save Changes</button>
</form>
kod
if request.method=='POST' and 'btnform1' in request.POST:
do something...
if request.method=='POST' and 'btnform2' in request.POST:
do something...
To już stare pytanie, jednak miałem ten sam problem i znalazłem rozwiązanie, które działa dla mnie: napisałem 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
Example:
In template:
<input type="submit" name="create_new" value="Create"/>
<input type="submit" name="delete" value="Delete"/>
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

Jeden adres url do tego samego widoku! właśnie tak!
###urls.py###
url(r'^$', views.landing.as_view(), name = 'landing'),
####views.py####
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,})
####/home.html####
#### form 1 ####
<form action="" method="POST" >
{% csrf_token %}
{{ register.as_p }}
<button type="submit" name="htmlsubmitbutton1">Login</button>
</form>
#### form 2 ####
<form action="" method="POST" >
{% csrf_token %}
{{ login.as_p }}
<button type="submit" name="htmlsubmitbutton2">Login</button>
</form>
