Question

我想了解在Class Base View中我将为以下内容执行逻辑：

enter image description here

基本上，我想检查用户是否有帐户，如果是这样，将它们转发到URL A，否则为URL B.但是，我不能100％确定get_success_url（）是否是最适合这种情况的地方。一个CBV或者如果Django有一些已经满足这个用例的东西。我见过其他CBV喜欢RedirectView我试过这个但是失去了范围。请记住，我需要传递用户ID。

这是我到目前为止所处的地方：

class CampaignView(BaseUpdateView):
    form_class = UserLookUpFrom
    model = Campaign


    def get_context_data(self, **kwargs):
        context = super(CampaignView, self).get_context_data(**kwargs)
        # context['form'] = AppUserLookUpFrom

        return context


    def form_valid(self, form):
        """
        If the form is valid, in this case DON'T save it!
        """
        return super(CampaignView, self).form_valid(form)


    def get_success_url(self):

        """
        Returns the supplied URL.
        """
        if self.success_url:
            url = self.success_url % self.object.__dict__
        else:
            try:
                currect_user = Campaign.object.get_user_by_email(EMAIL HERE DONT KNOW HOW TO GET THIS YET FROM FORM)
                if currect_user:
                         url = reverse('campaigns_login', args=(self.object.id,'self.userid'))
                else:
                         url = reverse('campaigns_register', args=(self.object.id)



            except AttributeError:
                raise ImproperlyConfigured(
                    "No URL to redirect to.  Either provide a url or define"
                    " a get_absolute_url method on the Model.")
        return url

Answer 1

您可以在form_valid本身执行此操作。这是一个未经测试的代码，应该有助于解释这个概念：

from django.shortcuts import redirect

def form_valid(self, form):
    email = form.cleaned_data.get("email", "")
    prev_user = Campaign.object.filter(email=email)
    if prev_user:
       return redirect('campaigns_login', self.object.id, prev_user[0].userid)
    else:
       return redirect('campaigns_register', self.object.id)

Answer 2

我认为它应该在CampaignView的帖子上：

def post(self, request, *args, **kwargs):
   form= self.form_class(request.POST)
   if form.is_valid():
      user_email= form.cleaned_data['email']
      user_of_campaign= Campaign.objects.filter(email= user_email)
      if len(user_of_campaign)>0:
         return redirect('/login', user_of_campaign[0].id)
      else: 
         return redirect('/register')
      return super(CampaignView, self).form_valid(form)
   return super(CampaignView, self).form_invalid(form)

在类基本视图中放置逻辑的位置？
