class User(object):
username=models.CharField()
xxx
pub_date = models.DateTimeField(auto_now_add=True)
class Notes(models.Modle):
author = models.ForeignKey(User)
title = models.CharField()
pub_date = models.DateTimeField(auto_now_add = True)
body = models.TextField()
两个模型，
怎么调用 最新写过日记的用户．
比如 用户 a, b,c 分别各写了几篇日记，怎么调用用户 a,b,c，以他们写日记的时间排序．

如果调用最新 10 篇用户文章 notes = Notes.objects.all().order_by(-‘ pub_date ’)[:10]
