Django個性化分頁

直接上代碼吧：

    state = login_status(request.user.is_authenticated())
    log_list = AccessLog.objects.all().order_by()
    paginator = Paginator(log_list, 10)

    try:

    except EmptyPage:
        current_page = paginator.page(paginator.num_pages)
    except PageNotAnInteger:
        current_page = paginator.page(1)

    return render(request, 'radius/accesslog.html', {
            'current_page': current_page,
            'paginator': paginator,
            'state': state
    })

   try:
