我在/blog/view/None/得到错误NoReverseMatch

Question

我要和Django一起写博客。当我试图访问一个特定的博客文章时，我得到了一个错误：NoReverseMatch at /blog/view/None/ Reverse for 'blog_like' not found. 'blog_like' is not a valid view function or pattern name.，我根本不知道是什么导致了这个问题。如能提供任何帮助，将不胜感激。

完全错误：

Answer 1

action="{% url 'blog_like' pk=blog_post.id %}"

您的urls.py文件没有名为"blog_like“的url。
