Django 1.6 UpdateView - 有def dispatch（）返回queryset返回

Question

在這個基礎視圖....假設queryset = self.objects.get(user_assigned=pk)有一個值...我想它將它返回到AccountModify所以def get_object(self, queryset=None):可以把它和返回它。眼下def get_object()不接受它，並返回空白queryset

class AccountCreateOrModify(object): 
    model = Employee 
    form_class = AccountForm 
    template_name = 'bot_data/account_modify.html' 
    success_url = reverse_lazy('home') 


class AccountModify(LoginRequiredMixin, 
     AccountCreateOrModify, 
     UpdateView): 

    def dispatch(self, request, 
      *args, **kwargs): 
     try: 
      pk = self.request.user.pk 
      queryset = self.model.objects.get(user_assigned=pk) 
     except Employee.DoesNotExist: 
      return redirect('account_add') 

     if request.method.lower() in self.http_method_names: 
      handler = getattr(self, request.method.lower(), self.http_method_not_allowed) 
     else: 
      handler = self.http_method_not_allowed 
     return handler(request, queryset) 

    def get_object(self, queryset=None): 
     return queryset

我看來，像你應該把查詢（...objects.get(user_assigned=pk)）的get_object方法內。

要重定向到account_add，你可以用調度方法是這樣的：

def dispatch(self, request, *args, **kwargs): 
    try: 
    return super(AccountModify, self).dispatch(request, *args, **kwargs) 
    except Employee.DoesNotExist: 
    return redirect('account_add')
