我在这里谈论Django 1.7.3：
在我的urls.py中，我有这条规则：url(r'^logout/$', 'django.contrib.auth.views.logout', {'next_page': '/'}, name='logout_url'),
在我的模板中，我尝试这样做：{% url 'logout_url' %}
计算机告诉我：type object argument after ** must be a mapping, not str并突出显示网址标记。
怎么了？ :(我尝试将next_page ='/'作为参数添加到标记中，或者从url定义中删除kwargs，制作我自己的调用d.c.a.v.logout的视图，我有点迷失。
