Submit two forms in a single submit in Django - django

Question

I have two forms in template. At the moment I have two submit buttons.
Would like to combine those to a single submit button.
Below code is now updating only one form, that's AnswerForm.
How i can update AnswerReplyForm along with that?
class AnswerView(ObjectEditView):
form_class = forms.AnswerReplyForm
answer_form = forms.AnswerForm
model = AnswerReply
def get(self, request, pk):
answer = get_object_or_404(Answer, pk = pk)
answer_reply = AnswerReply.objects.filter(answer_id = pk).order_by('-id')
self.answer_form = self.answer_form(instance=answer)
return render(request, 'helpdesk/answer.html', {
'answer': answer,
"answer_reply" : answer_reply,
'obj_type': 'answer reply',
'form': self.form_class,
"form2":self.answer_form,
"pre_reply_from" : self.predefined_reply_form
})
def post(self, request, pk, *args, **kwargs):
answer = get_object_or_404(Answer, id=pk)
answer_reply = AnswerReply.objects.filter(answer_id = pk).order_by('-id')
self.answer_form = self.answer_form(instance=answer)
obj = self.model()
obj = self.alter_obj(obj, request, args, kwargs)
form = self.form_class(request.POST, request.FILES, instance=obj)
if form.is_valid():
form.instance.answer_id = pk
obj_created = not form.instance.pk
obj = form.save()
return render(request, 'helpdesk/answer.html', {
'answer': answer,
"answer_reply" : answer_reply,
'obj_type': 'answer reply',
'form': self.form_class,
"form2":self.answer_form,
})

Answer 1

In general:
if request.method == 'POST':
form_1 = FormOne(request.POST)
form_2 = FormTwo(request.POST)
if form_1.is_valid() and form_2.is_valid():
form_1.save()
form_2.save()
return #Write your return here, something like HttpResposeRedirect or whatever you need to do after saving both form successfully
else:
form_1 = FormOne()
form_2 = FormTwo()
context = {
'form1': form_1,
'form2': form_2
}
return render(request, 'template.html', context)
In your template file
<form>
{{ form1 }}
{{ form2 }}
<input type="submit" value= "submit">
</form>
It will work.

Answer 2

It's better to define a structure for each one (View, route and template)
Then, based on desired condition, display one of the structures (redirect to one of them):
for example decision view:
def decisionView(request):
route = '/route/1'
if condition:
route = '/route/2'
return redirect(route)
i hope this could help you
