我有2类在我的models.py

class Product(models.Model):
ext...
and
class ProductImage(models.Model):
product=models.ForeignKey(Product, default=None, on_delete=models.CASCADE)
image=models.ImageField
views.py

def view_property(request, id):
    photo = get_object_or_404(ProductImage, id=id)
    product = get_object_or_404(Product, id=id)
    photos = ProductImage.objects.filter(product=product)
    context = {
        'photo':photo,
        'product':product,
        'photos': photos
    }
    return render(request,'products/view_property.html', context)

因此，为了在我的HTML页面中显示多个图像，我在www.example.com url.py中包含int：id或类似的东西url.py

from django.urls import path
from . import views

urlpatterns = [
    path( '<int:id>/' , views.view_property , name = 'view_property' ),
]

现在，当我想获取数据到我的view_property.html页面，我得到的图像过滤的ID罚款，所以它的工作原理，但问题是在我的view_property.html页面在页面上我有项目，每个项目包含的产品和图片在滑块，所以我想获取多个产品每个产品获取他的图像过滤ID view_property.html

<div class="box-container">
        {% for pro in products %}
        <div class="box">
            <div class="image-container">
                {% for img in photos %}
                <div class="mySlides"><img src="{{img.image.url}}" alt=""></div>
                {% endfor %}
            </div>
            <div class="content">
                <div class="location">
                    <p>apartments</p>
                </div>
            </div>
        </div>
        {% endfor %}
    </div>

她我得到一个产品的所有图像与每个项目相同的事情，因为我从url int：id获取一个产品的数据
我认为变化将在url.pyviews.py我希望我得到一个答案
我试着从www.example.com删除url.py

from django.urls import path
from . import views

urlpatterns = [
    path( 'view_property/' , views.view_property , name = 'view_property' ),
]

我想在view_property.html页面中添加int：id，正好在for循环中，但我不知道怎么做，但我尝试了这个例子：

<div class="box-container">
        {% for pro in products ***<int:id>***%}
        <div class="box">
            <div class="image-container">
                {% for img in photos %}
                <div class="mySlides"><img src="{{img.image.url}}" alt=""></div>
                {% endfor %}
            </div>
            <div class="content">
                <div class="location">
                    <p>apartments</p>
                </div>
            </div>
        </div>
        {% endfor %}
    </div>
