Question

我有一个简单的Django模型和Q查找，一切都按预期工作，但我希望过滤结果显示在单独的DIV中，同时保持原始查询列表未经过滤，如附加图像中的注释。下面是我的代码，带注释的屏幕截图以及dev服务器上页面的链接。任何指示都会很棒。谢谢。

def plaque_list(request):
    today = timezone.now().date()
    queryset_list = Plaque.objects.active().order_by("first_name")
    if request.user.is_staff or request.user.is_superuser:
        queryset_list = Plaque.objects.all().order_by("first_name")

    query = request.GET.get("q")
    if query:
        queryset_list = queryset_list.filter(
            Q(first_name__contains=query) |
            Q(last_name__icontains=query)
        ).distinct()
    paginator = Paginator(queryset_list, 8)  # Show 25 contacts per page
    page_request_var = "page"
    page = request.GET.get(page_request_var)
    try:
        queryset = paginator.page(page)
    except PageNotAnInteger:
        # If page is not an integer, deliver first page.
        queryset = paginator.page(1)
    except EmptyPage:
        # If page is out of range (e.g. 9999), deliver last page of results.
        queryset = paginator.page(paginator.num_pages)

    context = {
        "object_list": queryset,
        "queryset_list": queryset_list,
        "title": "Locate a Veteran",
        "page_request_var": page_request_var,
        "today": today,
    }
    return render(request, "plaques/plaque_list.html", context)

按照devxplorer的建议，只需在您的上下文字典中添加第二个查询集，然后使用它来呈现您的特殊div。

def plaque_list(request):
    today = timezone.now().date()
    queryset_list = Plaque.objects.active().order_by("first_name")
    if request.user.is_staff or request.user.is_superuser:
        queryset_list = Plaque.objects.all().order_by("first_name")

    query = request.GET.get("q")
    filtered_results = None
    if query:
        filtered_results = queryset_list.filter(
            Q(first_name__contains=query) |
            Q(last_name__icontains=query)
        ).distinct()
    paginator = Paginator(queryset_list, 8)  # Show 25 contacts per page
    page_request_var = "page"
    page = request.GET.get(page_request_var)
    try:
        queryset = paginator.page(page)
    except PageNotAnInteger:
        # If page is not an integer, deliver first page.
        queryset = paginator.page(1)
    except EmptyPage:
        # If page is out of range (e.g. 9999), deliver last page of results.
        queryset = paginator.page(paginator.num_pages)

    context = {
        "object_list": queryset,
        "queryset_list": queryset_list,
        'filtered_results': filtered_results,
        "title": "Locate a Veteran",
        "page_request_var": page_request_var,
        "today": today,
    }
    return render(request, "plaques/plaque_list.html", context)

然后你可以在那个特殊的div中循环filtered_results。
