Django個(gè)性化分頁(yè)

直接上代碼吧：

# views.py
def accesslog(request):
    state = login_status(request.user.is_authenticated())
    log_list = AccessLog.objects.all().order_by()
    paginator = Paginator(log_list, 10)
    current_page_num = request.GET.get('page', 1)
    try:
        current_page = paginator.page(current_page_num)
    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
    })
    
# templatetags/mytag.py

from django import template
register = template.Library()

@register.filter(name='substra')
def substra(value, arg):
   try:
      return int(value) - int(arg)
   except:
      return ''
