Question

以下是我的访问日志模型。如何仅显示每个用户的最新日志条目？

class AccessLog(models.Model):
    user = models.ForeignKey(User)
    datetime = models.DateTimeField(auto_now_add=True)
    summary = models.TextField()

    def __unicode__(self):
        return '%s %s %s' % (self.user.username, self.datetime, self.summary)

以下是一个示例日志：

Answer 1

这些方面的内容如何

class User(models.Model):
    ...
    @property
    def lastest_log(self):

        return AccessLog.objects.filter(user=self).latest('datetime')

然后循环

users = User.objects.all()

for user in users:
    print user.latest_log

获取访问日志的最简单方法是每个用户只显示一个条目
