और

Proper way to handle multiple forms on one page in Django।

if request.POST(): 
    a_valid = formA.is_valid() 
    b_valid = formB.is_valid() 
    c_valid = formC.is_valid() 
    # we do this since 'and' short circuits and we want to check to whole page for form errors 
    if a_valid and b_valid and c_valid: 
     a = formA.save() 
     b = formB.save(commit=False) 
     c = formC.save(commit=False) 
     b.foreignkeytoA = a 
     b.save() 
     c.foreignkeytoB = b 
     c.save()

class NegotiationGroupMultifacetedView(TemplateView): 
    ### TemplateResponseMixin 
    template_name = 'offers/offer_detail.html' 

    ### ContextMixin 
    def get_context_data(self, **kwargs): 
     """ Adds extra content to our template """ 
     context = super(NegotiationGroupDetailView, self).get_context_data(**kwargs) 

     ... 

     context['negotiation_bid_form'] = NegotiationBidForm(
      prefix='NegotiationBidForm', 
      ... 
      # Multiple 'submit' button paths should be handled in form's .save()/clean() 
      data = self.request.POST if bool(set(['NegotiationBidForm-submit-counter-bid',

     return context 

    ### NegotiationGroupDetailView 
    def post(self, request, *args, **kwargs): 
     context = self.get_context_data(**kwargs) 

     if context['negotiation_bid_form'].is_valid(): 
      instance = context['negotiation_bid_form'].save() 
      messages.success(request, 'Your offer bid #{0} has been submitted.'.format(instance.pk)) 
     elif context['offer_attachment_form'].is_valid(): 
      instance = context['offer_attachment_form'].save() 
      messages.success(request, 'Your offer attachment #{0} has been submitted.'.format(instance.pk)) 
       # advise of any errors 

     else 
      messages.error('Error(s) encountered during form processing, please review below and re-submit') 

     return self.render_to_response(context)
