Question

我希望获得给定两个年龄段之间的所有个人资料。示例“从年龄：20岁到30岁” 在我的模型而不是年龄，我保存了用户的出生日期。我需要将出生日期转换为年龄，并希望获得给定年龄之间的配置文件。如果问题不正确，请帮我纠正问题。

models.py

class profiles(models.Model):
    user = models.OneToOneField(User)
    full_name = models.CharField(max_length=200)
    birthday =  models.DateField(null=True)

    def age(self):
        return int((datetime.date.today() - self.birthday).days / 365.25  )
    age = property(age)

views.py

def search_results(request):
            from_age = form.cleaned_data['from_age']
            to_age = form.cleaned_data['to_age']
            query_set = profiles.objects.filter(gender=gender)
            if from_age < to_age:
                query_set = query_set.filter(
                    age__gte=from_age,
                    age__lte=to_age  
                )

Answer 1

您无法对属性进行过滤。

你应该反过来做：将年龄转换为日期，然后对其进行过滤。

Answer 2

尝试range查询：

import datetime

def search_results(request):
    from_age = form.cleaned_data['from_age']
    to_age = form.cleaned_data['to_age']

    now = datetime.date.today()
    from_date = datetime.date(now.year-int(to_age), now.month, now.day)
    to_date = datetime.date(now.year-int(from_age), now.month, now.day)

    query_set = profiles.objects.filter(gender=gender,
                                        birthday__range=(from_date, to_date))
