Django inlineformset_factory不会删除记录

Question

这是我的代码：

PartFormSet = inlineformset_factory(ReservationPaper, ReservationPaperPart,
                                    ReservationPaperPartEditForm, extra=0)
if request.method == "POST":
    try:
        part_formset = PartFormSet(data=request.POST, instance=rp)
    except:
        return HttpResponseRedirect(request.path_info)
    rp_form = ReservationPaperForm(instance=rp, data=request.POST)

    if part_formset.is_valid() and rp_form.is_valid():
        rp_form.save()
        for part_form in part_formset.forms:
            part_form.save()
        return HttpResponseRedirect(reverse("internal:documents:display_reservation_paper",
                                        args=[rp.id]))
else:
    rp_form = ReservationPaperForm(instance=rp)
    part_formset = PartFormSet(instance=rp)

它为每个part_formset实例呈现删除复选框，但是，当我提交表单时，只会编辑条目，而不会删除。

保存表单集时，您没有做任何特别的事情，因此您只需调用part_formset.save()而不是单独遍历表单。
