Django:没有反向url匹配多个参数

时间:2013-03-03 00:58:46

标签: django django-urls

我的网址需要捕获以下内容:

domain/forum-name/
domain/forum-name/topic-name

我有以下网址定义:

url(r'^$', views.index_forums, name='index_forums'),
url(r'^(?P<forum_name>[-\w]+)/(?P<topic_name>[-\w]+)/$', views.show_topic, name='show_topic'),
url(r'^(?P<forum_name>[-\w]+)/$', views.index_topics, name='index_topics'),

当我点击域名/论坛名称这样的网址时,我会在HTML中生成网址,如下所示:

{% url 'board:show_topic' forum_name|lower topic.title|lower %}

这给了我一个“反向...未找到”错误,我无法弄清楚原因。我错误地使用“url”了吗?我的正则表达式有问题吗?谢谢!

尝试:

{% url 'show_topic' forum_name|lower topic_name|lower %}

编辑:

您的网址正则表达式不接受空格:

尝试:

url(r'^(?P<forum_name>[-\w]+)/(?P<topic_name>[-\w\ ]+)/$', views.show_topic, name='show_topic'),
