Django模板；找不到“”的反转不是有效的视图函数或模式名称

此错误的原因是login.html中的以下行：

<p>Please, use the following form to log-in. If you don't have an account
<a href="{% url '' %}">register here</a></p>

通过使用空参数调用url模板标记，您自然会得到错误Reverse for '' not found.。解决方案是指定url名称：

<p>Please, use the following form to log-in. If you don't have an account
<a href="{% url 'register' %}">register here</a></p>

可能只是你的一个疏忽，总是发生在我身上：-）
