Question

我正在创建一个基于社区的网站，当我创建个人档案模型时，我将所有者作为用户的外键，但是在我看来

args['user'] = user = request.user
args['profile'] = UserCommunityProfile.objects.filter(owner = user)

我也尝试做owner_id__exact = user.id和owner_id = user.id，但还是不做

在模板中，如果我做{{ profile.count }}，我什么也没得到，为什么？这是我的模型.py

class UserCommunityProfile(models.Model):
    class Meta():
        db_table = "user_profile"
        verbose_name = "User Community Profile"
        verbose_name_plural = "Users Community Profiles"

    owner = models.ForeignKey(
        User,
        related_name="user_profile_user_key",
        verbose_name="owner of the profile",
        blank=False,
        null=False,
        on_delete = models.CASCADE,
    )
    DOB = models.DateField (
        auto_now=False,
        auto_now_add=False,
    )
    user_description = models.TextField (
        blank=False,
        null=False,
    )
    profile_picture = models.ImageField(
        upload_to='community-profile-pictures',
        default='default.png'
    )
    profile_creation = models.DateTimeField(
        auto_now_add=True
    )

    def __str__(self):
        return self.owner.username

无法在Django模板中使用item.count
