回溯驱动我疯狂，似乎无法找到调试源

Question

我已经通过我的模板，确保没有跟踪这个代码可以找到的地方，现在最终要求从stackoverflow社区帮助

你可能在你的模板：

{% url dashboard_follow_user something %} 

，其中一些是空字符串 “”，而你的urls.py可能说是这样的：

(r"/something/(?P<id>\d+)$"), "myview", {}, "dashboard_follow_user") 

它只是预计int或别的东西，但不是空字符串（“”）。

此堆栈跟踪的原因在于，在渲染逐个呈现模板元素时，这是通常的堆栈。
