Question

我已经尝试了几天使用get_absolute_url，每当我点击管理页面中的网站视图按钮或点击我的添加表单页面上的提交时，我都会收到此错误：

NoReverseMatch at /admin/r/14/3/ (or NoReverseMatch at /blogs/add/)

Reverse for 'blog_detail' with arguments '()' and keyword arguments '{'pk': 3}' not found. 0 pattern(s) tried: []

如果我去mysite / blog / 3，我确实得到了博客详细信息页面，因为我已经设置好了。所以我知道这个页面有效，但似乎没有尝试找到它，因为它表示尝试了零模式。

我正在查看的文档是：

https://docs.djangoproject.com/en/1.7/topics/class-based-views/generic-editing/ https://docs.djangoproject.com/en/1.7/ref/models/instances/#get-absolute-url

我的代码（我认为至少相关。如果需要更多信息，请告诉我们）
