def listing(request):

        if request.method == 'GET':
            search =  request.GET.get('search')       
            propertys = Paginator(Property.objects.filter(property_name__icontains =search).order_by('-listed_on'), 2)
            page = request.GET.get('page')
            propertys = propertys.get_page(page)
            nums = "p" * propertys.paginator.num_pages
            return render(request,"listing.html",{"propertys":propertys, "nums": nums, 'search':search})
        else:
            p = Paginator(Property.objects.order_by('-listed_on'), 2)
            page = request.GET.get('page')
            propertys = p.get_page(page)
            nums = "p" * propertys.paginator.num_pages
            return render(request,"listing.html", {"propertys":propertys, "nums": nums})

CodePudding user response：

You can't search by None in that way, but you can simply check first if search has a value other than None before you actually try it:

Replace

propertys = Paginator(Property.objects.filter(property_name__icontains =search).order_by('-listed_on'), 2)

with

if search:
    propertys = Paginator(Property.objects.filter(property_name__icontains =search).order_by('-listed_on'), 2)
