python - 如何在 Django 中按模型过滤模型

Question

我在从一组模型中过滤对象时遇到了一些麻烦。
我有3个类(class):

class Product(models.Model):
   id = models.UUIDField(default=uuid4, primary_key=True, editable=False)
   title_fa = models.CharField(max_length=80)
   title_en = models.CharField(max_length=80)
   ...

class Favorite(models.Model):
   user = models.ForeignKey(Profile, default=None, on_delete=models.CASCADE)
   product = models.ForeignKey('seller.Product', default=None, on_delete=models.CASCADE)
   ...

class Profile(models.Model):
   id = models.UUIDField(default=uuid4, primary_key=True, editable=False)
   first_name = models.CharField(max_length=80, blank=True, null=True)
   last_name = models.CharField(max_length=80, blank=True, null=True)
   shop_name = models.CharField(max_length=80, blank=True, null=True)
   ...

我试图过滤一些这样的东西:

favorite_product = Product.objects.filter(id=favorite__.id)

这是我的 View 功能:

def profile(request):
    id = request.COOKIES['id']
    order__ = Order.objects.filter(sender=id)
    profile__ = Profile.objects.get(id=id)
    favorite__ = Favorite.objects.filter(user=id)
    favorite_product = Product.objects.filter(id=favorite__.id)

    return render(request, 'shop/profile/profile.html',
                  {'order': order__, 'profile': profile__, 'favorite_product': favorite_product})

我想通过 user = id 显示他们 id 在最喜欢的模型中的产品。
模板代码:

{% for item in favorite_product %}
    <div class="profile-recent-fav">
        <a href="#"><img src="{{ item.image.url }}"></a>
        <div class="profile-recent-fav-col">
            <a href="#"></a>
            <div class="profile-recent-fav-price">{{ item.fa_name }}</div>
            <div class="profile-recent-fav-remove">
                <a href="#">
                    <i class="fa fa-trash"></i>
                </a>
            </div>
        </div>
    </div>
{% endfor %}
