Question

我有一些问题：

# models.py
class someinfo(models.Model):
    data1 = models.BigIntegerField(verbose_name='data1')
    data2 = models.BigIntegerField(verbose_name='data2')
    data_pubdate = models.DateTimeField(default=timezone.now, verbose_name='data_pubdate')
    people = models.ForeignKey(Drive, on_delete=models.CASCADE, verbose_name='people')

数据表有：

# row data
data1    data2        data_pubdate                people
7777129  23232        2017-05-18 05:04:08.377     9   
158160   4573279      2017-05-18 05:04:08.737     8
158200   5709307      2017-05-18 05:04:08.787     6
10073    11612        2017-05-18 05:04:19.727     6
2458     5245466      2017-05-18 05:04:19.727     4
2458     5245466      2017-05-18 05:04:19.724     4
14879    9727         2017-05-18 05:04:19.897     7
...etc

我想在每个人中选择来自new data_pubdate的data1和data2，如下表所示：

# select data
data1    data2        data_pubdate                people
7777129  23232        2017-05-18 05:04:08.377     9   
158160   4573279      2017-05-18 05:04:08.737     8
10073    11612        2017-05-18 05:04:19.727     6
2458     5245466      2017-05-18 05:04:19.727     4   
14879    9727         2017-05-18 05:04:19.897     7

所以......我该怎么办？

P.S。 django版本为“1.10”，数据库为“MSSQL server 2012”
