Django中带有DateTimeField的到期逻辑

本文介绍了Django中带有DateTimeField的到期逻辑的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在这样定义的服务模型中有一个DateTimeField：

I have a DateTimeField in a Service model defined like this:

pub_date = models.DateTimeField(default=timezone.now,blank=True)

我想在代码中创建一些到期逻辑，以便较早的服务超过2个月到期。我认为，只会显示那些尚未过期的服务。

I want to create some expiration logic in my code so that Services that are older than 2 months expire. In my view, only those services that aren't expired will be displayed.

例如，我想在视图中执行此操作：

For example I want to do this in a view:

views.py

class display_services:
    services = Service.objects.all()
    valid_services = []
    for service in service
        **If Service is Not Expired***
              valid_services.append(service)
    endfor
...

推荐答案

您可以按 pub_date

from datetime import datetime, timedelta

class DisplayServices(ListView):
    queryset = Service.objects.filter(pub_date__gte=datetime.now()-timedelta(days=60))

    ...
