python - 显示 Django Admin 的购买历史记录

Question

我试图在每个用户的仪表板上显示每个用户的购买历史记录。我在 Stripe 中制作了一些虚拟订单，这些订单正在运行，但我在页面的订单历史记录部分中显示订单时遇到困难。

我也不确定订单是否正确链接到注册用户，因为我似乎对这种方法感到困惑

有人可以帮助我或给我指出正确的方向吗？

<div class="container">
    <div class="row">
        <div class="col-sm-12 col-md-12 col-lg-12">
        	
    <table class="table table-striped">
    <h3>Your order history</h3>
    <hr>
    
  <tr>
    <th>Date</th>
    <th>Invoice ID</th> 
    <th>Description</th>
    <th>Total</th>
  </tr>
  {% for orders in orders %}
  <tr>
    <td scope="row">{{ order.quantity }}</td>
    <td>xxx</td>
    <td>xxx</td>
    <td>xxx</td>
  </tr>
  {% endfor %}

</table>
  
</div>

Answer 1

订单历史记录未显示，因为您使用了名为 orders 的循环变量，但在访问每个属性时引用了 order。将循环变量重命名为order:

{% for order in orders %}
<tr>
    <td scope="row">{{ order.quantity }}</td>
    <td>xxx</td>
    <td>xxx</td>
    <td>xxx</td>
</tr>
{% endfor %}
