Question

我是Django的新手，我正在尝试将用户身份验证添加到一个简单的应用中。我正在使用Django 1.9，我尽可能地尝试这样做。登录和注销工作，但使用＆＃34;更改密码＆＃34;，我收到了password_change_done的NoReverseMatch错误。

来自我的urls.py

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

在/league/templates/league/index.html中，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/ league / templates / registration /中创建了这些文件。 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＆＃34;更改密码＆＃34;链接，我明白了：

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

我知道＆＃34;更改密码完成＆＃34;链接很傻，但我添加它看看会发生什么。它工作正常。当我点击它时，会按预期显示password_change_done.html。

这是我点击＆＃34;更改密码＆＃34;时的堆栈跟踪。链接：

我在stackoverflow上发现了类似的情况，包括this one.

我将urls.py更改为：

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'),

但它没有任何区别，我仍然得到NoReverseMatch错误。

我对＃34;更改密码＆＃34;错误地做了什么想法？

谢谢，麦克

password_change查看does not use current_app参数以确定重定向网址。您需要显式传递视图名称，包括命名空间：

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

current_app参数仅用于模板中的{% url %}标记，但它是deprecated，将在Django 2.0中删除。如果您需要模板上下文中的当前应用，则需要设置request.current_app。

django password_change noreversematch
