如何在Django模型中创建失效日期? [英] How to I create an expiration date in my django model?

问题描述

我如何为仅在未过期时显示的新帖子创建过期日期选项?

How would I create an expiration date option for new posts that would only show when they are unexpired?

推荐答案

在您的模型中，您需要这样的东西:

In your model you need something like this:

expiration_date = models.DateTimeField()

然后在您的视图中，您可以像这样访问数据库:

Then in your views you could access the database like this:

def UnexpiredPosts(request):
    unexpired_posts = YourPostModelName.objects.filter(expiration_date__gt = datetime.now())

    return render(request, "path_to_template", {'Posts': unexpired_posts})

模板:

<ul>
{% for i in Posts %}
<li>{{ i }}</li>
{% endfor %}
</ul>
