Django 1.6 UpdateView - Have def dispatch() return queryset

Question

在这个基于类的视图....假设queryset = self.objects.get(user_assigned=pk)有一个值…我想让它把它还给AccountModify，这样def get_object(self, queryset=None):就可以拿走它并把它还给它。现在def get_object()没有收到它，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

Answer 1

在我看来，你应该把查询(...objects.get(user_assigned=pk))在get_object方法内。

要重定向到account_add，可以这样包装调度方法:

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