如何在python(Django)中基于日期时间范围过滤对象 [英] How to filter an object based on a datetime range in python (Django)

问题描述

我正在尝试创建一个包含所有最新帖子的页面.

I am trying to create a page with all the most recent posts.

class Post(models.Model):
     title = models.CharField(max_length=40)
     postTime = models.DateTimeField(auto_now_add=True)

我找到了这个例子:

 start_date = datetime.date(2005, 1, 1)
 end_date = datetime.date(2005, 3, 31)
 Post.objects.filter(postTime__range=(start_date, end_date))

我知道我想使用__range函数.但是如何做到这一点，这样我就可以获取从今天到两周前的所有帖子

I know I'm suppose to use the __range function. But how can I make it so that I can get all the posts from a range of today all the way to two weeks ago

类似这样的东西:

start_date = datetime.date(date from two weeks ago)
end_date = datetime.date(currentdate)
Post.objects.filter(postTime__range(start_date, end_date))

推荐答案

start_date = end_date - datetime.timedelta(days=14)
