在不使用 url 的情况下将值从 FormView form_valid() 发送到 success_url

Question

如何将这个值发送到success_url？

class AnyView(FormView):
    ...
    success_url = reverse_lazy('success')
    
    def form_valid(self, form):
        ...
        value = 'blablabla' # <<< How to pass this value?
        messages.success(self.request, f'Sua matrícula foi realizada.')
        return super(AnyView, self).form_valid(form)

success.html

{{ value }}

我不想通过url

发送

path('anyform', AnyView.as_view(), name='anyform'),

@alv2017 的评论对我有帮助。

class AnyView(FormView):
...

def get_context_data(self, **kwargs):
    context = super(AnyView, self).get_context_data()
    return context

def form_valid(self, form):
    ...
    context['value'] = 'blablabla'
    messages.success(self.request, f'Sua matrícula foi realizada.')
    return render(self.request, 'success.html', context)
