我在Django中实现了一个功能，它在一个单独的细节页面上显示订单细节
我还创建了一个自定义标签，它返回给定列表的长度范围（这工作正常）：
下面是我的模板：
{% extends 'Verification/main.html' %}
{% load custom_tags %}
{% block content %}
...
<table class="table">
{% for i in order.products|get_range %}
{{i}}
<tr>
<td>{{order.products.i.productId}}</td>
<td>
<tr>
<td>Prodcut Name</td>
<td>{{order.products_info.i.name}}</td>
</tr>
<tr>
<td>Prduct SKU</td>
<td>{{order.products_info.i.sku}}</td>
</tr>
<tr>
<td>Prodcut Image</td>
<tr>
{% for image in order.products_info.i.images %}
<td><a src="{{image}}" download><img src="{{image}}"></a></td>
{% endfor %}
</tr>
</tr>
<tr>
<td>Prodcut Name</td>
<td>{{order.products_info.i.name}}</td>
</tr>
</td>
</tr>
{% endfor %}
</table>
...我面临的问题是循环{% for i in order.products}下的数据|get_range %}没有被渲染我用数字0，1，2替换了i（因为列表的长度为3），以检查问题是否在上下文字典中，但它不是渲染数据的情况，而是当我使用i时。
下面是从veiw传递到template的上下文字典：

看起来问题出在您尝试使用索引i访问order.products列表的方式上。在模板中，不能使用变量动态访问对象的属性
