def communityClass(request):
    com = request.GET.get('com')
    result = campmodel.CommunityInfo.objects.filter(
        com=com).order_by("-time")[:10]
    data = []
    for i in result:
        data.append({"id": i.id, "time": str(i.time), "title": i.title,
                     "content": i.content, "picture": str(i.picture)})
    return HttpResponse(json.dumps(data))
