Question

在Django 2.0.5中正在做网上商店示例，尝试将购物车检出到订单页面时遇到了URL错误。它将错误带到下面

找不到页面（404）请求方法：GET 要求网址：http://127.0.0.1:8000/cart/%25%20url Django使用myshop.urls中定义的URLconf，按以下顺序尝试了以下URL模式：

admin/
orders/
cart/ [name='cart_detail']
cart/ add/<int:product_id>/ [name='cart_add']
cart/ remove/<int:product_id>/ [name='cart_remove']
[name='product_list']
<slug:category_slug>/ [name='product_list_by_category']
<int:id>/<slug:slug>/ [name='product_detail']
^media\/(?P<path>.*)$

当前路径，购物车/％网址，与任何这些都不匹配。

尝试

嗨，在detail.html中出错：

href="{% url "shop:product_list" %}"

如果使用外部双引号，则使用单引号或双引号，然后使用内部单引号，然后应无错误显示：试试吧：

href="{% url 'shop:product_list' %}"

无法从购物车页面-Django URL错误访问我的网上商店的订单页面
