锚定标签不'；t将项目提交给购物车python django

我的

制服

模型显示了一个项目仪表板。我正在尝试将项目发送到购物车以签出项目。我在加载我的内部服务器时没有问题，也没有调试问题。但是，当查看我的管理订单项目模型时，没有向其推送任何内容：

最初，我尝试了一次添加一个项目的按钮，它工作了，但没有添加任何其他项目，现在链接作为一个整体无法工作。我的

视图.py

中是否缺少某些内容？

如果需要，您可以轻松使用

urlpatterns

列表中

path

元素的

name

属性在项目中导航，而无需更改url本身。要使用此功能，可以使用以下语法进行指定：

{{url''arg1=arg.data}

其中是

urlpatterns

的

path

元素的

name

属性，如我上面所说；arg1不需要作为参数传递，arg.data是要传递的数据

HTML

<div class="col-lg-10">
    <a href="{{ url 'add_to_cart' slug=item.slug }}" class="btn btn-primary">Add to Cart</a>
</div>

如果它不起作用，请告诉我。

请从项目的

url.py

文件中添加

urlpatterns

，在该文件中可以找到url将项目添加到购物车。@PythonNewbie我做了更新。我正在处理这个项目的slug，没有任何东西被推过，也没有错误
