问个django的问题……
我按着这个教程一直做下去的，

结果运行时就出错了……

google了一晚都没结果。就看到google论坛上有一个貌似和我看同一个教程的也出

现这种错误……不过没有解决办法……


我的配置
URL：
urlpatterns = patterns('blog.apps.homepage.views',
  url(r'^about/$', 'about', name="homepage_about"),
)


模板里：

<a href="{% url homepage_about %}">about</a>


views.py

def about(request):
  return render_to_response('homepage/about.html')


project

谁能告诉我怎么改才可以正常运行？
谢谢！

[解决办法]
Reverse for 'homepage_about' with arguments '()' and keyword arguments '{}' not found

你好像没有传参数过去啊？打点log看看。
[解决办法]
模板里改成这样

Python code

<a href="{% url 'homepage_about' %}">about</a>
[解决办法]
观看<a href="{% url 'homepage_about' %}">about</a>
