查询集的 Django 分页

Question

我正在基于过滤的query 实现pagination，它在单击页码之前可以正常工作，但在单击页码后它会显示所有对象，包括未过滤的对象。 升级到最新版本的 django 后开始发生。

点击前分页。

点击第2页后的分页。

fitered objects 是4 并且给定2 items per page paginator 分页应该在Page number 2 处停止，但它显示了一个新的分页器，其中包含所有对象，即使是未过滤的对象。 下面是一些sn-ps。任何帮助将不胜感激。

Views.py

def searchPropertyListView(request):
 city = City.objects.all().annotate(
     num_property=Count("property")).order_by("-num_property")
 categories = Category.objects.all()
 purposes = Purpose.objects.all()

 featured = list(Property.objects.filter(featured=True))
 shuffle(featured)

 querySet = Property.objects.all()
 city_or_neighborhood = request.GET.get('city_or_neighborhood')
 category = request.GET.get('category')
 purpose = request.GET.get('purpose')

 if city_or_neighborhood != '' and city_or_neighborhood is not None:
     querySet = querySet.filter(Q(city__title__icontains=city_or_neighborhood)
                               | Q(neighborhood__title__icontains=city_or_neighborhood)
                               ).distinct()
 elif category != '' and category is not None:
     querySet = querySet.filter(category__title=category)

 elif purpose != '' and purpose is not None:
     querySet = querySet.filter(purpose__title=purpose)

 paginator = Paginator(querySet, 2)

 page = request.GET.get('page')

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

 context = {
     'city': city,
     'featured': featured,
     'querySet': querySet,
     'categories': categories,
     'purposes': purposes,
 }

 return render(request, 'search/search_list.html', context)
