推荐答案

截至django 1.5 {％url url_name ％} 将该参数视为上下文变量，而 {％url'url_name'％} 将为您提供名为url_name的URL。在以前的版本中，后一种语法是错误的，不行。

As of django 1.5 {% url url_name %} would treat the argument as a context variable, whereas {% url 'url_name' %} would give you the url named 'url_name'. In prior versions, the latter syntax is wrong, and won't work.
