#错误抓取三个方式

#单个条件抓取
try:
	uid = UserProfile.objects.get(username = request.user.username).id
except UserProfile.DoesNotExist:
	return HttpResponse("error");

#多个条件抓取
try:
	m = datatime_log.objects.get(userid = uid, id = request.POST["numberId"])
except (ValueError, datatime_log.DoesNotExist): 
    return HttpResponse("error");

#只要有错误就抓取
tyr:
    m = datatime_log.objects.get(userid = uid, id = request.POST["numberId"])
except Exception:
    return HttpResponse("error");
