Python Can'；我不能保存表格

我有一个问题，提交按钮表单未保存后无法保存表单。我只能在管理仪表板上完成

class EventPage(CreateView):
    template_name = 'event.html'
    form_class = RegisterToEvent
    second_form_class = UploadDocument

    def form_valid(self, form, **kwargs):
        form.instance.event = Event.objects.get(id = self.kwargs['event_id'])
        form.save()
        return super(EventPage, self).form_valid(form)

    def form_invalid(self, **kwargs):
        return self.render_to_response(self.get_context_data(**kwargs))

    def get_context_data(self, **kwargs):
        context = super(EventPage, self).get_context_data(**kwargs)
        event = Event.objects.get(id = self.kwargs['event_id'])
        participants = Participant.objects.filter(event_id = event.id)
        context['participants'] = participants
        context['event'] = event
        if 'RegisterToEvent' not in context:
            context['RegisterToEvent'] = self.form_class
        if 'UploadDocument' not in context:
            context['UploadDocument'] = self.second_form_class
        return context

    def get_object(self):
        return get_object_or_404(Event, pk=self.kwargs['event_id'])

    def post(self, request, *args, **kwargs):
        self.object = self.get_object()
        if 'register_form' in request.POST:
            form_class = self.get_form_class()
            form_name = 'RegisterToEvent'
        else:
            form_class = self.second_form_class
            form_name = 'UploadDocument'
        form = self.get_form(form_class)
        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_invalid(**{form_name: form})

我有两种表格：RegisterToEvent和UploadDocuments。问题是当我试图将注册表保存到事件窗体时。我没有得到任何错误，只有

url.py

urlpatterns = [
    url(r'^$', 'event.views.home', name='home'),
    url(r'^about/', 'meetingsSystem.views.about', name='about'),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^accounts/', include('registration.backends.default.urls')),
    url(r'^create-event/', 'event.views.create_event', name='create_event'),
    url(r'^event-(?P<event_id>[0-9]+)/$', EventPage.as_view()),
]

if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root = settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

urlpatterns=[
url（r'^$'，'event.views.home'，name='home'），
url（r“^about/”、“meetingsSystem.views.about”、name='about'），
url（r“^admin/”，包括（admin.site.url）），
url（r“^accounts/”，包括（'registration.backends.default.url'），
url（r“^create event/”，“event.views.create_event”，name='create_event'），
url（r'^event-（？P[0-9]+）/$，EventPage.as_view（）），
]
如果设置为.DEBUG：
urlpatterns+=静态（settings.static\u URL，document\u root=settings.static\u root）
urlpatterns+=静态（settings.MEDIA\u URL，document\u root=settings.MEDIA\u root）

你能再做一点调查吗？你的URL.py正确吗？它到达EventPage类中的post（）函数了吗？我编辑了这个问题。我想URL是正确的。你确定你的表单。你的表单返回真的吗？是的，我尝试了表单的打印测试。你如何执行post请求？也许您正在使用ajax执行表单提交？
