django password_change noreversematch

Question

我是新来的Django，我试图添加用户身份验证到一个简单的应用程序。我正在使用Django 1.9，我正在尽可能简单地做到这一点。登录和注销工作，但使用“更改密码”，我得到一个NoReverseMatch的password_change_done错误。

从我的urls.py

app_name = 'league' 
urlpatterns = [ 
    url(r'^$', views.index, name='index'), 
    url('^', include('django.contrib.auth.urls')), 
] 

在/league/templates/league/index.html，我有：

<a href="{% url 'league:login' %}">Login</a> 
<a href="{% url 'league:logout' %}">Logout</a> 
<a href="{% url 'league:password_change' %}">Change Password</a> 
<a href="{% url 'league:password_change_done' %}">Change Password Done</a> 

我在创建这些文件/联盟/模板/注册/ 。 password_change_form.html和password_change_done.html目前什么都不做，它们只包含一个显示的字符串。

• 的login.html
• logged_out.html
• password_change_form.html
• password_change_done.html

当我点击 “更改密码” 链接，我得到：

NoReverseMatch at /league/password_change/ 
Reverse for 'password_change_done' with arguments'()' and keyword arguments '{}' not found. 

我知道“更改密码已完成”链接是sil但是我添加了它来查看会发生什么。它工作正常。当我点击它时，按预期显示password_change_done.html。

下面是当我点击“更改密码”链接的堆栈跟踪：

我发现计算器类似案件，其中包括this one.

我改变了我的urls.py这样：

url(r'^password_change/$', 
    auth_views.password_change, 
    {'current_app': 'league'}, 
    name='password_change'), 
url(r'^password_change_done/$', 
    auth_views.password_change_done, 
    {'current_app': 'league'}, 
    name='password_change_done'), 

但它没有区别，我仍然得到NoReverseMatch错误。

任何想法我做错了“更改密码”？

谢谢， 迈克

的password_change视图does not use的current_app参数来确定重定向URL。你需要明确传递视图名称，包括命名空间：

url(r'^password_change/$', 
    auth_views.password_change, 
    {'post_change_redirect': 'league:password_change_done'}, 
    name='password_change'), 

的current_app参数只在模板中的{% url %}标签使用，但它是deprecated，并会在Django 2.0中删除。如果您需要模板上下文中的当前应用程序，则需要设置request.current_app。
