我试图计算 model object 但它不起作用

Question

I'm trying to count model object using Django but it's not working, it doesn't display anything, that's the HTML code, I've tried both.all.count and.count but both aren't showing anything

<div class="card">
        <div> <h3>Followers: {{profiles.follower.all.count}}</h3> </div>
        <div> <h3>Followings: {{profiles.following.count}}</h3> </div>
</div>

这就是 python 配置文件 function 代码

def profile(request, username):
    user = get_object_or_404(User, username=username)
    user_posts= post.objects.filter(user=user)
    profiles = Userprofile.objects.filter(user=user)
    context = {
        'user_posts':user_posts,
        'profiles': profiles
    }
    return render(request, "network/profile.html", context)

**我的模特**

class User(AbstractUser):
    pass

class post(models.Model):
    user = models.ForeignKey('User', on_delete=models.CASCADE, related_name='maker')
    text = models.CharField(max_length=255)
    date = models.DateTimeField(default=datetime.now())
    likes = models.ManyToManyField('User', blank=True)

class Userprofile(models.Model):
    user = models.ForeignKey('User', on_delete=models.CASCADE, related_name='profile')
    follower = models.ManyToManyField('User', blank=True, related_name='follower')
    following = models.ManyToManyField('User', blank=True, related_name='following')

在你的views.py中添加.first() ：

def profile(request, username):
    ....
    user_posts= post.objects.filter(user=user).first()
    profiles = Userprofile.objects.filter(user=user).first()
    ......
