Django：如何在提交表单后重定向到具有分页的ListView？

Question

我正在使用Django bootstrap模式形式，当我从分页页面更新一些记录时，它会重定向到列表视图的第一页。我想将其重定向到所选/更新记录的分页页面。

My list view with update in the left corner and pop up modal form to update it

单击“保存”后，它将重定向到没有分页参数的记录列表，如何在成功URL中添加分页参数。请帮忙

我的views.py

def record_list(request):
    queryset_list = Record.objects.filter(recorded__lte=timezone.now()).order_by('-recorded')

    query = request.GET.get("q")

    if query:
        for term in query.split():
            queryset_list = Record.objects.filter(Q(persons__last_name__icontains=term) |
                                                  Q(persons__first_name__icontains=term) |
                                                  Q(persons__middle_name__icontains=term) |
                                                  Q(title__icontains=term)
                                                  )

    paginator = Paginator(queryset_list.order_by('-recorded'), 10)
    page_request_var = "page"
    page = request.GET.get('page', 1)

    try:
        queryset = paginator.page(page)
    except PageNotAnInteger:
        queryset = paginator.page(1)
    except EmptyPage:
        queryset = paginator.page(paginator.num_pages)

    context = {
        "record_list": queryset,
        "page_request_var": page_request_var,
        "title": "List",
    }

    return render(request, 'Bato_Cabugao/Record/record_list.html', context)

class RecordUpdateView(LoginRequiredMixin,generic.UpdateView):
    template_name = 'Bato_Cabugao/Record/record_update.html'
    model = Record
    form_class = RecordForm

models.朋友

class Record(models.Model):
    title = models.CharField(max_length=200)
    persons = models.ManyToManyField(Person)
    details = models.TextField()
    recorded = models.DateTimeField(default=timezone.now)

    def __str__(self):

Answer 1

将current page number和Record数据一起发送到UpdateView。然后在View中定义get_success_url方法，如下所示。

class RecordUpdateView(LoginRequiredMixin,generic.UpdateView):
    ...

    def get_success_url(self):
        current_page = self.request.POST.get('current_page')

        return <url_to_record_list> + '?page=' + current_page

假设您在request.GET或request.POST中拥有当前页码，则可以构造并返回所需的最终URL。
