ValueError：int() 的无效文字，基数为 10：'favicon.ico'

Question

我无法弄清楚为什么会出现此错误。我明白错误的含义，但不明白为什么“favicon.ico”出现在错误本身中。

回滚迁移，编辑 urls.py，擦除数据库，回滚代码。

这是模型，如果有帮助的话：

ValueError：int() 的无效文字，基数为 10：'favicon.ico'

Answer 1

Web 浏览器将始终请求 /favicon.ico，它是选项卡中显示的图标。例如这里这张图片左边的图标是stackoverflow的

您可能有一个匹配任何内容并需要一个整数的 URL 模式。您应该将模式更改为仅接受整数，path('<int:foo>/', view, name='your-view')并且如果您想要一个图标，您应该配置您的网络服务器以提供图标/favicon.ico，您可以使用<head>页面中的标记更改位置以提供图标<link rel="shortcut icon" href="/other-path-to-my-icon/icon.ico" />

编辑：

有问题的模式是path('<str:pk>/', web.views.case_detail, name='case_detail'),您应该将匹配更改为，'<int:pk>/'因为案例模型的 PK 是 int
