对于超过5小时的对象，Django会查询datetime

问题描述

我正在为超过5小时的小部件编写一个Django查询，我有点迷失了。小部件模型有一个 DateTimeField ，填充了小部件的创建时间。

I'm trying to write a Django query for widgets that are more than 5 hours old and I'm a bit lost. The widget model has a DateTimeField that is populated with the creation time of the widget.

推荐答案

如果 Widget 是您的模型的名称，并且具有名为的DateTimeField属性创建，则查询将是：

If Widget is the name of your model, and it has a DateTimeField attribute named created, the query would be:

from datetime import datetime, timedelta

time_threshold = datetime.now() - timedelta(hours=5)
results = Widget.objects.filter(created__lt=time_threshold)

请注意， created__lt 表示已创建小于。

Note that created__lt means "created is less than".
