Django分页：编辑后重定向到特定页面（FBV）

Question

我在 Django 中使用分页列出了 300 条客户记录。每页包含 20 条记录。假设我在第 7 页并选择了要编辑的记录。编辑记录后，成功的 url 重定向列表视图（这是第一页）。所以我想，如果我在?page=7 中编辑，当客户id 完成编辑时，它会回到?page=7。

这里是我在view.py 中的customer_list 视图：

def customer_list(request):
    posts_list = Customer.objects.all()
    query = request.GET.get('q')
    if query:
        posts_list = Customer.objects.filter(
            Q(invoice__addresses__contact_number__icontains=query) |
            Q(invoice__addresses__address__icontains=query) |
            Q(shipping_method__icontains=query) 
        ).distinct()
    page = request.GET.get('page')
    paginator = Paginator(posts_list, 20)  # 20 posts per page
    try:
        posts = paginator.page(page)
    except PageNotAnInteger:
        posts = paginator.page(1)
    except EmptyPage:
        posts = paginator.page(paginator.num_pages)

    context = {
        'posts': posts,
        'page': page
    }
    return render(request, "customers/customer_list.html", context)

这里是update_customer_list在view.py中查看：

def update_customer_list(request, id):
    """
       Here, update single customer id form customer table
       :param request:
       :param id:
       :return:
       """
    obj = get_object_or_404(Customer, pk=id)
    form = CustomerForm(request.POST or None, instance=obj)
    if form.is_valid():
        form.save()
        messages.add_message(request, messages.SUCCESS, 'Customer successfully Updated')
        return redirect('customer_list')
    return render(request, 'customers/customerUpdateForm.html', {'form': form})

这里是update_customer_listurls.py中的网址：

path('update_customer_list/<int:id>/', views.update_customer_list, name='update_customer_list'),

我正在等待某人的帮助，我们将不胜感激...

您将页面参数传递给您拥有的 url 和内部函数：

from django.shortcuts import reverse_lazy
def update_customer_list(request, id):
"""
   Here, update single customer id form customer table
   :param request:
   :param id:
   :return:
   """
page = request.GET.get("page") 
obj = get_object_or_404(Customer, pk=id)
form = CustomerForm(request.POST or None, instance=obj)
if form.is_valid():
    form.save()
    messages.add_message(request, messages.SUCCESS, 'Customer successfully Updated')
    url = reverse_lazy("customer_list") + "?page=" + page
    return redirect(url)
return render(request, 'customers/customerUpdateForm.html', {'form': form})
