如何过滤django-oscar产品以仅显示特定类别的产品？

from oscar.apps.catalogue.models import Product, ProductCategory

def filter_products_by_category(request, category_slug):
    # 获取特定类别的产品
    category = ProductCategory.objects.get(slug=category_slug)
    products = Product.objects.filter(categories=category)

    # 返回过滤后的产品列表
    return render(request, 'products.html', {'products': products})

{% for product in products %}
    <div>
        <h3>{{ product.title }}</h3>
        <p>{{ product.description }}</p>
    </div>
{% endfor %}
