在页面 bills.html 我有表单(操作 - order_page.html )。
在页面 order_page.html 我有表单,其中一个字段必须具有来自 bills.html 的表单的值。
views.py:
class OrderPage(TemplateView):
template_name = 'order_page.html'
form_class = BillAmount
def post(self, request, *args, **kwargs):
context = self.get_context_data()
form = self.form_class(request.POST)
if form.is_valid():
amount = form.cleaned_data['sum'] # this value I need in get_context_data()
return super(OrderPage, self).render_to_response(context)
def get_context_data(self, **kwargs):
amount = 2314 # here I need value from post()
ctx = super(OrderPage, self).get_context_data(**kwargs)
ctx['form'] = FinishPaymentForm(instance=payment) # another form
return ctx
我不知道,怎么做。我尝试使用 post():OrderPage.amount = N
和许多其他变体,但它们不起作用。
怎么做?
谢谢!

试试这个:
class OrderPage(TemplateView):
...
amount = None
def post(self, request, *args, **kwargs):
...
if form.is_valid():
self.amount = form.cleaned_data['sum']
...
def get_context_data(self, **kwargs):
# Here you can use self.amount
...
