Django最后一页分页重定向 [英] Django last page pagination redirect
问题描述
我的问题类似于此问题.唯一的区别是我使用GCBV进行分页.我的查看文件如下:
My problem is similar to this problem. The only difference is I use GCBV for my pagination. My view file is as follows:
class ChatListView(ListView):
model = Chat
form_class = NewMessageForm
template_name = 'chat.html'
paginate_by = 5
queryset = model.objects.all() ###not needed
def post(self, request, *args, **kwargs):
form = self.form_class(request.POST)
if form.is_valid():
form.save()
return redirect('chat') <--- here
return render(request, self.template_name, {'form': form})
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['form'] = NewMessageForm() # edited: self.form_class
return context
我希望post方法重定向到分页的最后一页.在链接中,它是通过return HttpResponseRedirect('/forum/topic/%s/?page=%s' % (topic.slug, posts.num_pages))
实现的.但是对于我的GCBV,我不知道如何通过对象获取.num_pages
.请提供一些帮助.
What I want the post method to redirect to the last page of the pagination. In the link, it was achieved by return HttpResponseRedirect('/forum/topic/%s/?page=%s' % (topic.slug, posts.num_pages))
. But for my GCBV, I don't know how to get the .num_pages
via an object. A little help please.
推荐答案
您可以调用get_context_data
,这将对查询集进行分页并在上下文中包含paginator
.然后,您可以使用paginator.num_pages
访问页面数.
You could call get_context_data
, which will paginate the queryset and include paginator
in the context. You can then access the number of pages with paginator.num_pages
.
from django.urls import reverse
class ChatListView(ListView):
...
def post(self, request, *args, **kwargs):
form = self.form_class(request.POST)
if form.is_valid():
form.save()
self.object_list = self.get_queryset() # get_context_data expects self.object_list to be set
context = self.get_context_data()
paginator = context['paginator']
num_pages = paginator.num_pages
return redirect(reverse('chat') + '?page=%s' % paginator.num_pages)
