python - 如何从数据库生日字段和 date.today() 计算确切的年龄？

Question

我有两个日期:

1. 来自数据库的查询集，其中包含日期字段 (1992-11-15) 和 date.today()

这是我的观点.py

    def pop(request):
    start = randint(0, 2)
    finish = randint(2, 5)
    current_year = [date.today().year, date.today().year]
    context = {
        'alluserprofiles': zip(Profile.objects.all()[start:finish], 
    current_year),
        'maleuserprofiles': zip(Profile.objects.filter(gender='male'), current_year),
        'femaleuserprofiles': zip(Profile.objects.filter(gender='female'), current_year),
        'start': start,
        'finish': finish
    }
    return render(request, 'users/pop.html', context)

这是我的 django 模板

   {% for profile, year in alluserprofiles %}
<div class="container fixed-top" id="pop-up">
  <div class="card text-center border-light mb-3">
    <img class="card-img-top" src="{{ profile.image_prof.url }}" />
    <div class="card-body">
            <h5> {{ profile.user }} {{ year|sub:profile.birthday.year}}

如何减去它们以获得准确的年龄？我只能进行年份减法。

非常感谢

from datetime import datetime

birthday = datetime(1988, 2, 19, 12, 0, 0)
diff = datetime.now() - birthday
print diff
# 8954 days, 7:03:45.765329
