在Jinja2中检查日期时间对象是否与今天一致

Question

I would like to test whether a python datetime object agrees with today within the browser, using jinja2

Something like

{% if current_user.last_seen_datetime.date() == TODAY %}

how would I get TODAY?

Answer 1

I found the simples solution is to add a function to the User class

def show_paper_suggestions(self):
    if self.last_seen_datetime is None:
        return 1
    else:
        return (datetime.datetime.utcnow() - self.last_seen_datetime).days
